Just as Lu Chen was thinking about whether to take Chu Zihang and the others for another lap, he suddenly turned his head vigilantly, and a figure was walking towards them about a few hundred meters away.

　　The visitor is slim and slender, with long legs that are even more eye-catching. Wearing a white tights and a long single ponytail, he doesn't look like a scientific researcher in any way.

　　 At this time, the woman waved at several people with a happy smile on her face.

　　 Perceiving Lu Chen's movements, Fingel and Chu Zihang also turned their heads and looked at the woman.

　　 Finger pushed Chuzi Channel: "Junior Brother, I've been freezing for a long time and have hallucinations. Why would I see a long-legged supermodel on the snow?"

　　 "Brother, you read that right, there is indeed a woman."

　　 Chu Zihang replied lightly.

　　 Several people stood up, Lu Chen stared at the woman, analyzing her strength from the other's steps.

　　 Then Lu Chen shook his hand slightly behind him, meaning there was no danger.

　　 Jiu De Mai ran all the way, smiled and greeted a few people, embarrassed that she wanted to go into the ice cave, but as a ninja, she must be cheeky.

　　 "Are you Junior Brother Lu, Junior Brother Chu, and Senior Brother Fingel?"

　　 When the few people were still a little confused, Jiu De Mai enthusiastically shook hands with Lu Chen and the others one by one.

"You are?"

　　 Lu Chen asked in doubt.

　　 "Kassel College Level 04, Jiu De Ya Ji, the Executive Department sent me to assist the commissioners, and also brought snake venom serum."

　　 As he said, Jiu De Mai also took out an executive department commissioner's card, and a small box containing snake venom serum.

This was the extra "materials" that the boss asked to bring before she came. She was still wondering at the time. She didn't expect that the group of black snakes would actually show up. She herself was useless, and Chu Zihang couldn't use it now, but It is indeed a good reason.

　　 Lu Chen received the executive department commissioner's card from the other party. He opened it and took a closer look at the watermark on the anti-counterfeiting office. There was nothing wrong with it.

　　 "Thank you senpai for coming to support, but are you alone?"

　　 Lu Chen first expressed his gratitude. There are two things in the college that are difficult to forge, one is the student card, and the other is the certificate of the commissioner of the executive department.

　　 Besides, they lost contact for a few days, and it made sense that the Executive Department sent people to support the investigation.

　　 "We dispatched two teams, but because of the snow storm, they were separated and my supplies were lost. I have been hiking in the ice field these days, but no one else was found."

　　 Jiude Mai sighed, looking worried for her companion.

　　 As for the documents, of course there is no problem. The highest level of forgery is "produced by the original factory." With their ability, it is not a problem to obtain a few documents from the Executive Department. She still has a student card!

　　 "I hope everyone else is okay."

Lu Chen expressed his condolences, but he estimated that after crossing that snowstorm, most of the other executive department commissioners were queued outside. Only the "lucky" senior sister of Jiu De was also involved in Nibelungen's. In the cracks.

　　 "Wine De Aki?"

　　Finger looked at the woman in front of him, with a trace of suspicion in his eyes, and Jiude Mai's mind suddenly became nervous.

　　 The only flaw in her disguise, where it may be seen, is on Fingel, because this guy is level 01!

　　 In theory, she should have been with the other party in the college, and she doesn't know if her sister has ever met this guy.

　　 "Brother, do you remember me?"

　　 Jiu De Mai showed a happy look, but his heart was tense.

Fingel examined Jiude Mai from top to bottom, and wondered: "Didn't you just graduate last year? I seemed to have met you at the graduation ceremony, but how do I feel...you seem to have grown taller? "

　　Finger wondered that the younger sister in front of him looked familiar, but how did he remember that the other party’s legs weren’t so long before, and why did they stretch after graduation?

　　 "Brother, in your mind, am I a little woman with short legs?"

　　 Jiu De Mai tried to endure the nausea and made a grotesque look.

　　 She and Jiu De Aki are oviparous sisters, their looks are indeed very similar. If you only look at the upper body and add makeup, it is difficult for unfamiliar people to tell, but she never expected that her long legs would betray her.

　　 "Haha, I didn't mean that."

　　 Fingel waved his hand, and said that maybe he was thinking too much. After all, he did have this person in his impression, and his appearance was not different.

　　 "Sister Jiu De, you seem to have just graduated. Since the Executive Department has sent you here, you should have special skills?"

　　 The questions that Chu Zihang asked were always serious. As for the story of this senior sister and Senior Brother Fingel, he... can't say that he is not interested, but they are in a serious situation right now.

　　 "Just call me Aki...Does the leg length count?"

Jiude Mai didn’t laugh when seeing a few people, and the cold wind in the far north seemed to be getting colder, so he said with a straight face: “I have also had experience facing suspected Dragon King’s targets, and I’ve been studying Nibe when I was in school. Longgen's various characteristics have also published papers, so the executive department sent me to help the juniors find their goals."

　　 Lu Chen picked up the bronze statue and shook it, "We found this at the extreme point. It is assumed that Nibelungen is nearby, but we can't find the entrance."

　　 "It's useless for you, brother, to search like this. You have also had experience in Nibelungen before. You should know that the medium is very important."

　　 Jiu De Mai looked at the bronze statue and said.

　　 Chu Zihang thought slightly, squatting down to push the snow away, "The medium that enters the Nibelungen is usually a medium such as mirrors and water. There is no shortage of mirrors and water here."

He thinks that the medium is everywhere, and he and Senior Brother Fingel also have the mark of the Dragon King. Moreover, they are already in the cracks of the Nibelungen. In theory, they have been "invited", but why can't they get in? ?

　　 "Junior Brother, what you said is not entirely correct. Just because there are media everywhere here, there are no special abnormalities. We also need other media."

　　 Jiu De Mai and Chu Zihang discussed.

　　 Lu Chen and Fingel took a step back consciously, saying that this kind of discussion has nothing to do with the scumbag. You say yours, we only need the result.

　　 "Water, ice, mirror surface, but also need special points..." Chu Zihang silently analyzed, suddenly his eyes lighted, and said: "Sister, you mean, you still need light!"

　　 Jiu De Mai snapped her fingers, "Bingo! You deserve to be Junior Brother Chu."

　　 Lu Chen couldn't help hearing this, pointed to the sun in the sky, and asked in confusion, "This is a vast expanse of white, the light is so good, we don't lack light."

　　 Chu Zihang explained: "Brother Lu, Sister Yaji is talking about a special light...Aurora."

　　 This time even Fingel was a little fascinated, "Junior brother, I am a scumbag, but I also have common sense. Now the spring equinox is over, and the extreme day is near the extreme day, there is no night at all, where is the aurora?"

Jude Mai looked at Fingel, smiled, and explained: "Aurora is a large-scale discharge process around the earth. The charged particles from the sun reach the vicinity of the earth, and the earth’s magnetic field forces some of them to concentrate along the magnetic field lines. When the north and south poles enter the upper atmosphere of the polar regions, they collide with and excite atoms and molecules in the atmosphere to produce light and form aurora. So on this level, aurora always exists, but there are strong and weak. In the daytime, the sunlight is too strong for us to see."

　　 Lu Chen nodded repeatedly. In fact, he didn't understand the profound language in the middle, but he didn't want to be despised like Brother Fingel.

　　 "But there is another problem. Physically speaking, there are aurora, but Brother Fingel is also right. It has been daytime and we can't see aurora."

　　 Chu Zihang frowned slightly, and they seemed to have gone to a dead end again.

　　 "There will be aurora, just wait until a special time."

Jiu De Mai pointed to the sky, "Norma of the Executive Department calculated that at 23:49 tonight, there will be a total solar eclipse that can only be observed in the North Pole. This is a century-long cycle operation. During this operation, all parts of the world will see a total solar eclipse at different times. According to Norma's calculation and analysis, by July 22 this year, you will see a total solar eclipse in many areas of your hometown."

Several people in Lu Chen were a little surprised when they heard this. Even Lu Chen didn't ask why the time of appearance is different in each region, because even he now knows the difference in latitude and longitude, and the angle of the moon's occlusion is not the same at all, it's just in the big cycle. Within a year, there will be several places around the world where you can see a total solar eclipse.

　　 "So, we can enter Nibelungen tonight?"

　　 Finger raised his spirits at this time, even he was fed up with circling the endless snowy field.

　　 "This is theoretically possible, but we have to make preparations first. According to the experts of the executive department, it is possible that when the projection of the aurora falls in the mirror, the door of Nibelungen will open."

　　 Jiu De Mai said, and raised his hands, "Say yes, Sister Sister, I am just an assistant. After I help you find Nibelungen, even if my task is completed, don't take me in with me."

Lu Chen nodded, "Senior Sister is right. This time Brother Chu and I will go in for this mission. Senior Brother Fingel and Senior Sister are on standby outside. We will solve the goal as soon as possible, and the outside domain should be relieved by then. "

　　 He didn't even want to bring Chu Zihang, but Brother Chu was very stubborn, and now he has gained new strength, he didn't want him to go in and fight alone.

And Senior Brother Fingel... forget it, he admitted that Senior Brother Fingel is not a real waste dog, and the bronze throne is also a good speech spirit, but the Nibelungen who entered the Dragon King does not have the power of half the next generation. Just give it for nothing.

　　 Chu Zihang glanced at Senior Sister Yaji, still feeling that this incident was weird. He didn't doubt the identity of the other party. After all, the other party was not malicious, and he couldn't think of anyone to help them except the academy.

He just thought it was a coincidence. If the opening condition of the Nibelungen on this permafrost is the need for aurora, perhaps a special aurora, that is, the aurora under a total solar eclipse... Too harsh, and they can happen to happen.

　　 This feeling is like a pair of destiny pushing hands invisibly, pushing them to the Nibelungen of the Dragon King. This feeling is not good.

　　 "Right, brothers and sisters."

　　 Jiu De Mai's expression suddenly became a little embarrassed. She has never been so embarrassed since she became a teacher, "...you guys, do you have anything to eat? Senior sister, I haven't eaten for almost two days."

　　 After coming to the conclusion that Nibelungen might appear tonight, the few people are in a good mood at this time, so they started cooking.

　　 Jiu De Mai and Lu Chen got together and they were elegantly eating the canned food specially provided by the college. I have to say that the taste is not bad.

　　 She saw that the people in Lu Chen didn't doubt herself that much, and she couldn't help feeling that the old lady was really a capable acting school. Originally, they discussed letting Sanwu Niu come with her on this mission.

　　 But the boss rejected it, saying that Sanwu Niu should not be allowed to come to this land.

　　 Now think about how wise the boss is. If you bring Sanwu Niu with you, you can't hide it. The girl has a cold face and can freeze to death.

　　 Besides, Sanwu Niu will go to school next year, so I can’t jump inside first.

　　 After eating, Lu Chen got up and started "cleaning" the ice sheet.

　　 Because of the perennial snow and wind on this land boundary, there is thick snow on the ground, covering the ice surface.

　　 In case the aurora needs to be reflected in the mirror to achieve perfect conditions, they don't want to fall short.

　　 "Tsk tsk, I think even if Junior Brother Lu doesn't come to the academy, just relying on this physical strength to work is definitely a good way to make a fortune."

　　 Finger looked at Lu Chen, who was sweeping the floor with Hei Xuan whistling, and screamed again.

　　 "...With Brother Lu's character, sooner or later he will come to the academy."

Chu Zihang understands what kind of person Lu brother is. After the other party can't open the martial arts hall in his hometown, he will definitely rush to the world~lightnovelpub.net~ to start his own adventure, and sooner or later he will encounter extraordinary powers. With Brother Lu's combat power, he would definitely be paid attention to by the Academy.

　　Blood grief always separates people from normal society, and gathers people who should be together... to report to the group for warmth.

　　 When Lu Chen finished the work, it was already three o'clock in the afternoon. If it was in the Lionsheart Club’s office at this time, maybe Milana and Susie had already made tea for them, and after drinking the tea, they would continue to correct the documents.

　　 It's a pity that this is the Arctic Icefield, and they don't have such an elegant thing as tea.

　　 Among the supplies distributed by the executive department, only energy drinks, a bottle of it after heating, can hold up the calories for half a day...Of course, not for Lu Chen and the current Chu Zihang.

　　The waiting time is long. Considering that there may be a big battle after entering Nibelungen, several people are not busy sitting and chatting.

　　 There was only one tent. Based on the principle of ladies first, Jiu De Mai was allowed to rest for four hours first, and then the three of Lu Chen gritted their teeth and squeezed to sleep.

　　 At eleven o'clock in the evening, several people packed up and carried the necessary supplies with them.

　　 Lu Chen also put on the combat uniform under his coat, and carried Piaoxue and Izumi Mamoru on his waist, with a huge Hei Xuan behind him.

　　 At eleven forty-nine, as "Aki-senpai" said, it was dark.
