Although Huanghualing is located in Susong County, due to the special nature of the arsenal, the defenders stationed here are one of the companies of the Tiger and Leopard Battalion, with about 150 people, all of which are elites among the elites.

They may not necessarily know Yu Wan, but they must all know the devil instructor Jiang Ning. Although after many days, his hideous face still lingers in the minds of the soldiers.

With Jiang Ning's clearance, they also came to the arsenal without any obstacles.

The manager of the arsenal was Zhou Xiong. Under his introduction, everyone quickly gained a three-dimensional understanding of the place.

The Huanghualing Arsenal is guarded by a high stone wall, covering an area of ​​dozens of acres and is divided into three areas. The front area is used to store materials, the middle area is used to produce various parts, and the back area is used to assemble and store weapons and equipment.

The latest batch of muskets are placed here. Compared with old muskets, the appearance is not only more beautiful and simple, but also has a new level of accuracy.

Although there are only more than a hundred people in the factory, the security work is not leaked. In addition to the Minggang, there are more than a dozen secret wards, all equipped with the latest muskets. Suspicious people are approaching and shooting immediately!

Under the leadership of Manager Zhou, they soon arrived at the most core and mysterious underground research room of Huanghualing Arsenal, which is the secret place where Dai Zi conducts weapons research.

This underground research room is designed very tightly. After the entrance is placed in the kitchen window, the secret mechanism behind the stove must be activated to open the door. Except for Dai Zi himself and Zhou Guanshi, no one knows the existence of this place.

"Yes, this secret room is bigger than Brother Wan's room!"

Walking on the bluestone steps and looking at the stone chamber of hundreds of square meters, Xu Hu couldn't help but raise his thumb and exclaim.

"This place is indeed hidden enough, it is a bit cold and harsh and the air is very depressed and turbid. By the way, add a few more lamps in the future. Magistrate Fan can still afford this lamp."

Fortunately, Yu Wan's vision group did not fall down after stepping on the air. Everyone fumbled carefully for a while before they arrived on the floor.

Manager Zhou smiled bitterly and said, "It's not that we don't want to add lights, but that Master Dai refused to let him light them. He said that he was afraid that too many lights would easily detonate the gunpowder in the basement. Even his laboratory only had a small lantern hanging.

Speaking of which, Master Dai suffered a lot. Except for bedtime, he spent almost all of his time in the basement. He worked hard every day until the middle of the night before coming up. Sometimes he was so busy that he didn't even care about eating. Because of this, he developed the first batch of new muskets in just one month!"

After hearing what Manager Zhou said, Yu Wan couldn't help but be respectful to Dai Zi. This was really a workaholic who devoted himself to science. He didn't even give him a serious position, and just worked hard all the time.

"Where is Dai Zi's secret room?"

Manager Zhou pointed to the dark passage in front and said, "Just behind the stone wall on the left side of this passage!"

"Okay, go in and see him."

Everyone accelerated their pace and kept approaching the secret room. At this moment, a huge roar came, and the entire basement shook suddenly. Everyone stood unsteadily and fell on the wet floor!

"The earth...is an earthquake?"

Xu Hu rubbed his eyes with lingering fear, looked at the stone wall with panic in his expression, and his voice was filled with unspeakable fear.

"No, something happened to Dai Zi!"

Yu Wan came to his senses first, struggled and rushed to the development room without looking back.

The secret room was messy and dark. The pungent smoke of gunpowder made Yu Wan's eyes moist. After searching for a long time, he saw Master Dai lying on the ground.

"Brother Dai!"

Yu Wan dragged Dai Zi out and shouted to the people who were stunned on the ground, "Come and help!"

Jiang Ning pinched Dai Zi's man, Xu Hu slapped his limbs, and Manager Zhou also used his sleeves to help him clean the black stains on his face.

"call!"

Dai Zi suddenly opened his eyes and murmured to himself, "I didn't touch the fuse at all, why did this bomb explode when it was thrown?"

After a moment, he stood up and grabbed Manager Zhou's hand with his eyes and said, "I understand! Although he did not touch the fuse of the bomb, when the gunpowder density is too high, violent collisions can also detonate the bomb!"

Although blood was still emitting from the corners of his eyes, he was still so happy that he danced. Manager Zhou's hand was almost cut off by him.

"Dai...Master Dai, Master Yu is here to see you!"

Prefect Yu? Dai Zi was stunned for a moment, then moved his eyes to Yu Wan. He blinked his eyes and stared for a while before crying happily and said, "Prince Yu, why are you here!"

Yu Wan smiled and patted the dust on his shoulder, "Come and see you."

“It’s coming just right.”

Dai Zi pulled Yu Wan and walked towards the corner of the stone chamber. "In addition to those spears, I have also developed dozens of bombs! The bombs are a weapon buried in the ground. Once they touch the lead, they will automatically explode and can kill people invisibly!"

Hearing Dai Zi say this, Xu Hu also came over, "Yes, Old Dai, you have developed such amazing things. Why is your brain so easy to use? It seems that no one can offend you in the future!"

Dai Zi smiled and said, "Actually, this thing came out more than a hundred years ago. I just improved it, Master Yu, please give me a name!"

Fire up the cannon? Yu Wan was stunned for a moment. Through the faint light, he could vaguely see dozens of spherical objects the size of two fists in the basket. After listening to Dai Zi's narration, Yu Wan was happy and said: Isn't this a landmine? Haha, is mine war going to rise so soon?

Yu Wan moaned deeply for a moment before saying, "Since it's buried in the ground, it's called a landmine!"

"Mine...good name!"

Everyone said in a compliment.

Xu Hu touched the hot sweat on his chest and said impatiently, "This ghost place is too hot, hurry up and go out and have some breathing. By the way, try the mines that I have worn, don't just be powerful!"

"Okay, Huanghualing produces wild boars. Dai will invite you to have an explosive roasted suckling pig!"
