"Do you still remember the faintly heard explosion sound when I was approaching the bottom of the mountain?" Cheng Bo looked at Biyuetan deeply with both eyes, and said: "I guess that the explosion sound came from here, and, Look at the gravel on the ground, the traces are all new, and the minced meat that I don’t know where it came from. It seems to be very new, and I don’t know what the meat is. What happened here, is it related to Hua? Shu and they are related?"

"How could it have something to do with them? The explosion always has a bomb. Do you think they might have a bomb?" Song Zihao didn't believe it, saying that Hua Shu and Dong Chang were Lianjiazi. He believed that the explosion was related to them. But he didn't believe it.

After thinking about it carefully, Cheng Bo also felt reasonable. Although Hua Shu's backpack hadn't been seen in detail, he probably knew what she had brought, and it was indeed impossible to carry dangerous things like bombs.

Song Zihao has a restless nature, Cheng Bo is still in a daze by the pool, he has already come to the other side, paying attention to the destroyed vegetation.

At this point, he found the problem. Not all of these plants were destroyed by the bombing. He saw signs of burning and signs of freezing. Those branches of branches also showed signs of external force breaking. Signs.

"Cheng Bo, look at these plants and trees, it's strange." He called Cheng Bo quickly and judged that there was no problem with these traces, but if he thinks more deeply, he has self-knowledge, let's let his mind come in!

Cheng Bo walked to him quickly, took a closer look at his gesture, and immediately found the problem, but Cheng Bo, who had always been smart, was blind this time.

"What's going on? I can understand that the fire is caused by the explosion. The broken trees can also be said to be caused by the huge energy generated by the explosion, but how did the obvious signs of freezing come from?"

Cheng Bo was also puzzled at this moment, and there seemed to be something strange in the chaotic scene of Biyuetan.

"Cheng Bo, are you really sure, are Hua Shu and the others here?" Song Zihao glanced around and frowned.

"I was just guessing. I thought I could find them here, but I didn't expect that this place became the scene, and I didn't see them. I don't know if my guess is right or not." Cheng Bo was also helpless. How did he know that this place would become such a weird look?

In the past two days, he noticed that Hua Shu seemed to have a strange concern for Biyuetan. After the earth movement happened last night, not only Hua Shu, but also Dong Chang also paid attention to Biyuetan. The two of them were still mysterious. He didn't know what he was talking about, and he secretly had doubts in his heart. Therefore, when Hua Shu and Dong Chang both disappeared, the first thing he thought of was Biyuetan, which is why he brought Song Zihao back here to find them.

Song Zihao sighed helplessly, "What should we do now, if we haven't found them, shall we just go back like this?"

"Wait a minute, look around again, look for any clues." Cheng Bo was not reconciled, he always felt that his guess was not wrong.

"Okay, then!" Song Zihao shrugged indifferently. He didn't know where to look anyway, so he listened to Chengbo's arrangement.

The two were looking for clues about Hua Shu and Dong Chang around Biyuetan. At the bottom of Biyuetan, Hua Shu had already penetrated the formation on the stone wall, flipped his fingers, and entered the formation pattern with mysterious magic techniques.

The formation pattern on the stone wall lit up with a ray of light, but this ray of light quickly annihilated after a short while, and the entire formation also disappeared.

The originally ordinary stone wall revealed its true colors at the moment when the formation disappeared, and a stone gate and Youshen's invisible passage appeared in front of the two of them.

"Are we going in?" Dong Chang looked at the dark passage and hesitated, "It looks dark, what if there is any danger in it?"

"It's all here, I'm a bit unwilling to see if I don't go in." Of course, Hua Shu is also afraid of danger, but nowadays, she wants to go in and see what's in it.

"If you don't want to go, just wait for me here, I'll go in and see, if there is no danger, I will come out and call you."

She could see that Dong Chang was a little restless now. It was probably the first time he had fought a monster face to face with a monster, which had a big impact on her.

"No, let's go together." Dong Chang objected immediately. Although she felt the darkness was a bit scary, she wanted Xiaoshu to venture in by herself, but she was waiting outside. She couldn't do it.

"But you..."

"No problem, I can. It's just a bit dark. I'm not afraid at all." At this time, if you admit that you are afraid, Xiao Shu will definitely let herself stay here and wait for her.

Seeing her persistence, Hua Shu didn't say any more, "Well, let's go in."

The cave was big enough for three people to walk side by side. Dong Chang took a deep breath, boldly entered the dark cave with Hua Shu, and walked side by side with Hua Shu without hesitation, carefully guarding the surroundings and making sure He decided to fight side by side with Hua Shu and advance and retreat together.

She still had fear in her heart, but Xiaoshu was right. It took time and energy to solve the formation. It would be a shame not to go in and take a look. Maybe there is really any treasure in it? It's just that girls are naturally timid and afraid of the dark, and when they see the dark cave in front of them, they can't help being afraid.

Moreover, through the two formations encountered, this cave was obviously left by the immortal cultivator. Maybe there were some dangerous organs or monsters in it. Therefore, besides being afraid, she was more worried. .

There is a transparent barrier at the entrance of the cave, which cuts off the water outside, but people can pass normally. However, the cave that originally looked dark, after entering the cave, after a short period of darkness, it presents another scene. .

There are four square passages, and the walls are portrayed with landscapes and buildings. Looking along the way, Hua Shu found that the murals described in these murals are actually the daily life of a sect in the name of making formations.

The two quickly reached the end of the passage. There was a door in front of them, and the top of the door was engraved with the words "Ten Thousand Arrays".

"Ten Thousand Formation Sect, it turned out to be a sect specializing in formations!" Dong Chang looked at the words on the top of the gate, and said with some disappointment: "Although the formations are powerful, it should be compared with the battle-oriented sect. Is it weak? I think maybe even the three aspects of pill, talisman, and weapon are better than formations."

"The formation is still very powerful, especially the higher the formation, the stronger the lethality, but compared with the combat power of the disciple, it is indeed not as good as the fighting sect, and the fuzhuan and the magic weapon are both auxiliary to the battle. The important method is indeed stronger."
