"There is one more thing to tell my mother, Dad and Grandpa are poisoned and they are still in a coma. I want to take you to see them." Qin Fei said.

Although he already knew his life and was not a member of the Qin family at all, he still felt that he was the Qin family, and did not have that family relationship with the royal family, except for Zhu Li, of course.

"Poisoned?"

The mother stood up suddenly, her face was full of concern, and her eyes were worried.

"Mother, do you actually still like my father?" Qin Fei smiled brightly.

"Little Guitou, although my mother was pregnant with you because of destiny, your father is very good to me. It's normal for us to love each other. What's ridiculous?" Mother asked slightly strangely.

Qin Fei smiled comfortably: "Then rest assured, I will take you to see them right away and detoxify by the way!"

...

After talking to Zhu Li, Qin Fei and his mother left the imperial capital.

Those who left together were the iron wand, the owl, and the sky spear!

The sky spear came because of his mission. His only purpose of existence was to protect Qin Fei. He used to be secretly, but now he is upright.

As for the other disciples of the Iron Fort, they were kept by Zhu Li. The use of Xuan Ling Spear and Xuan Ling Cannon was not so easy to use, and someone who knew how to refining was needed.

So those people stayed and picked out those who were suitable for refining.

The refining technique finally began to flourish after six hundred years.

No words all the way, across the hills, across the long river, across the sky, a few people soon came to the iron fort.

The iron castle no longer needs to be hidden now. Zhu Li has issued the imperial decree, and the iron castle will officially appear in the eyes of the world.

"Brother Han!"

Seeing Qin Han sleeping, his mother threw herself on her body, feeling very sad.

Qin Fei walked over, supported his mother, and said, "Mother, don't be sad. Dad will wake up soon."

He put the refined Universe Pill into his father's mouth, and then fed one to his grandfather and Qin Yun.

"Let's go out and wait, the medicine may last for a day." Qin Fei said.

The mother shook her head and said, "I'm here waiting for your father to wake up. You can go out first!"

Qin Fei nodded, then turned and left with Iron Rod.

Sitting in the hall, Qin Fei looked around at everyone, and the people in charge in the iron castle had arrived.

"How many guns have we made now?" Qin Fei said.

"Master, there are five thousand Xuanling Guns, one thousand Xuanling Cannons, of which six hundred Xuanling Guns and three hundred Xuanling Cannons were given to the emperor, and the rest are still in the warehouse!" Tie Chang said.

"Well, take them out and send them to Beixuancheng to arrange them. The barbarians look at the Central Plains. I feel that we must have a battle with them. But Beixuancheng is located at the junction. We have to bear the brunt. Preparation!" Qin Fei said.

"In addition, let the brothers in the fort work harder and try to make as many guns as possible, as well as the Xuanyi. I have also improved them and refined them together!" Qin Fei took out a stack of blueprints. Both are Xuanyi's improved methods.

Tie Chang was overjoyed, holding Xuanyi's drawing and smiling from ear to ear.

There are endless black stones in the iron castle, so there is no need to worry about materials.

Mo Xiao suddenly said: "Master, I have an idea. I found that when using the mysterious spirit gun, the user's own safety cannot be guaranteed. Once the enemy gets close, it loses its effect. I want to design With the equipment that protects the life of the user, even if the enemy is close, there is no alternative, and the lethality will be stronger."

Qin Fei's eyes lit up, "Yes, armor!"

"Armor is not good either, the armor of the profound weapon can only resist a part of the lethality at most, and the enemy will still lose the effect of the profound spirit spear if it is close to the body. My idea is to make a big cage." Mo Xiao said.

"Big cage? Damn! Who wants to stay in the cage?" Qin Fei frowned.

"That's true, I have to think about it again."

Mo Xiao reacted, his method was really not good.

Qin Fei was awakened by him, and said, "Although the cage you mentioned is not good, do you think the carriage is good? We designed something like a carriage that allows people to hide in the carriage and use the mysterious spirit gun. Let's refining it all with black stone. In this way, ordinary people can't break the defense of the carriage. In this way, the people inside are equivalent to an extra layer of protection and can safely kill the enemy!"

"Master is great, carriage is a good way!" Mo Xiao's eyes lit up.

"Or did you remind me, how are you familiar with refining tools?" Qin Fei smiled.

"Hey, I was also a refiner back then, but I changed my career later!" Mo Xiao smiled.

"That way, you can stay in the iron fort and study with the iron rods." Qin Fei nodded.

"Then your safety?" Demon Xiao said.

"There is a sky spear, don't worry!" Qin Fei pointed to the sky spear that stood upright on the side. This guy was so cool that he never took the initiative to speak, standing aside like a pillar.

Mo Xiao glanced at the sky spear, and said nothing.

With the sky spear, no one would hurt Qin Fei unless he met another master of the level of a prince.

In Beixuancheng, a newly opened moat has been penetrated. The river is as wide as twenty feet, and the depth is not bottomless. There is a suspension bridge in front of the city gate. When war arises, the suspension bridge can be retracted to block the enemy's attack with a wide river surface. .

The widened and heightened city wall stands majestically on the bank of the river. The reinforced part is all piled up with cyan boulders. From a distance, it looks like a fierce cyan behemoth, entrenched on the ground, guarding its home.

The passage on the city wall is ten feet wide, enough for tens of thousands of people to walk freely on it without being crowded.

Every five meters, a tall and thick tower rises up. The inside of the building is a forbidden area. According to the rules, people are not allowed to enter at ordinary times. Entry is only allowed during war. No one knows what is inside, but judging from the strict guards, there must be very important things inside.

The walls of Beixuan City are very different from the walls of other cities. Every five meters of wall stacks, there will be a two-meter-high stone wall.

The walls of other cities are generally not built with such high wall stacks, after all, it is not convenient to resist the siege enemy.

Such a weird building, even Wang Wen, the master architect in the palace, was very confused. He felt that it had no effect at all, but it seemed nondescript.

But this is what the king of the town meant, he didn't dare to say anything, he could only do so.

Early in the morning, the suspension bridge outside the city gate was filled with the most important powerful figures in the city.

Everyone was standing at the gate of the city, looking around, as if waiting for someone to arrive.

The civilians entering and leaving the city gate were surprised when they saw these big shots. Who is coming? It's so exciting.

The most noticeable among them are the two people standing in the front, a man and a woman. The man has dark skin, a strong body, and his muscles are bulging like graves, full of explosive power.

The woman has a delicate face and a graceful figure, wearing a white leather armor, a long bow behind her, a huge quiver hanging from her waist, and a weird long bow in her hands.

The most striking thing is a pair of slender and straight legs.

Behind the man and the woman, there are neatly arranged nearly five hundred young people standing upright, all of whom are no more than twenty years old.

Pedestrians were surprised to see them and whispered.

"Xiao Jing, they are talking about us again! Hehe!" Bai Yi glanced in the distance and said to Bai Jing with a smile.

Bai Jing glared at him and said, "Brother, leave them alone, I have to set an example for everyone!"

She pointed to the straight young people behind her.

Bai Yi's face immediately turned straight, and stood upright without squinting.

People are talking about who is coming?

At this time, a cloud of dust rose up on the official road in the distance, with the sound of horseshoes and the sound of wheels.

Everyone looked serious.

coming!

Soon, two horse-drawn carriages appeared, and beside the carriage, a person was running along.

Bai Yi yelled: "What the hell? That man actually runs faster than a horse!"

Everyone's eyes were looked at by the person running by the carriage, and he was shrouded in black robes. Only two eyeballs exuding a deep chill from time to time, apart from that, nothing was clear.

The carriage stopped outside the moat and Wang Wen took the lead to greet him. Bai Yi looked back at the hundreds of young people and said loudly, "Stand well, accept inspection!"

Wow!

The neat stepping sound resounded through the hollow of the city wall, and everyone's expressions became serious.

At this time, the carriage door curtain opened, revealing a chiseled face.
