Leng Feng didn't know that the two of them thought of him as a hermit master, and the three of them just used their feet to go all the way to the ordnance prison.

The master craftsman of the ordnance supervisor knew Leng Feng, and heard that Leng Feng brought two people over to see the Eight Bull Crossbows, and they came out without putting on their shoes.

The prototype of the new eight-ox crossbow was made by Guogong, although Huangfu Ming made improvements to it or something, but, in the final analysis, it was Guogong who made the greatest contribution. Now that Guogong is here, maybe he has some new ideas!

Seeing that Wu Tian, the master of the ordnance supervisor, didn't have his shoes on, he ran out to greet him, Leng Feng said helplessly: "I'm not a rare guest, what do you mean by welcoming you like this!" ”

Wu Tian said embarrassedly: "Why aren't you a rare guest, you haven't been here once, even if you sent the drawings, or your subordinates came to send them, we prepared a banquet in vain." ”

"Okay, it's useless to talk about it, hurry up and get me an eight-bull crossbow, I want to experiment."

"Hey! Let's go find it! ”

Wu Tian smiled and took his men to the warehouse to push the eight-ox crossbow, and the ordnance supervisor usually stored an eight-ox crossbow, as a model, it was a trebuchet or something, and there were also.

Gong Yi, who had been silent, spoke: "Guogong, I don't know, can I take a look at other equipment?" ”

"This...."Leng Feng looked at Wu Tian.

Wu Tian said embarrassedly: "Although I don't know who this person is, but Guogong, there are too many secrets of the ordnance supervisor, you have to think about the villain." ”

The public lost and was speechless for a while, and the dignified public lost family, would they still covet your broken secret?

Leng Feng smiled: "Don't worry, it'll be fine, you can take us into the warehouse." ”

Seeing Leng Feng as a guarantor, Wu Tiancai nodded and led the three of them to the treasury of the ordnance supervisor.

The perimeter of the warehouse is tightly guarded, and the doors are all solid iron plate doors, and when opened, the contents are revealed.

The eight-bull crossbow is the most conspicuous, and then there is a trebuchet, a siege ladder or something, and the sight of the public is the first to fall on the siege ladder.

The most famous deed left in history by the Gongyi family is the cloud ladder, which is a siege weapon, and now when I see the siege ladder, I really can't help but show the superiority of my family.

"This broken ladder is used to siege the city? How many people would have to die! ”

Wu Tian didn't know the identity of Gong Yipo, and when he heard him say this, he couldn't help but say angrily: "I respect you as a friend of the Duke of Guo, but if you question our weapons supervisor, I will be polite!" Broken ladders? Do you know how many enemy cities Datang has captured with this broken ladder? You...."

Leng Feng stretched out his hand to stop him from continuing, and asked Gong Yipo instead: "Then what do you think the siege ladder is easy to use?" ”

Gong Yipo walked to the siege ladder and pouted: "This thing can also be called a siege ladder?" Wrapped in iron sheets, it looks sturdy, but when someone pokes it, it falls down. And this place, isn't this damn just folding! When it came time to siege the city, it had to be folded into a long ladder in advance before it could be used.

Comparatively speaking, my ladder not only has a support and poke-proof footing, but also can be lifted vertically, and when it comes to fighting, the bottom shelf, it will climb up and extend, this.... Right! ”

Gong Yipo shut up after saying a few words, it was a matter of their family's secrets, and it was really hard to say much.

Wu Tian felt that what this person said was very reasonable, and wanted to refute it, but he didn't know what to say, so he could only look at Leng Feng.

Leng Feng shrugged: "Don't look at me, he has the most say in the ladder, okay, find me the key to the eight-bull crossbow pulley, I want to open the pulley, by the way, find me an open space, I have to shoot an arrow!" ”

Wu Tian nodded and sent someone to get the key.

In order to avoid being stolen by the enemy, the pulley block is not only equipped with a self-destruct device, but also locked on the outside, which is extremely protected.

Gong Yipo walked to the side of the eight-bull crossbow and tried to pull the string.

His size can only be said to be slightly stronger, even the strings of the rhubarb crossbow, and he can't even pull it. However, something strange happened, and with his movements, the crossbow strings of the Eight Bull Crossbow actually moved obviously!

It's really obvious!

"I didn't lie to you!"

Leng Feng said proudly: "After the pulley group, it doesn't take much effort to wind the Eight Bull Crossbow, in fact, as long as you try your best, you can shoot an arrow." ”

Letting go of his hand, Gong Chuan Po looked at the pulley: "Is this what makes winding convenient?" Interesting! Although it is really not very difficult to pull the crossbow, but the power still needs to be seen! ”

Leng Feng nodded, beckoning Wu Tian and his subordinates to push the Eight Bull Crossbow out.

For experiments, just find a wall. The armory supervisor had an earthen wall, which was used to experiment with something, and after several people pushed the eight-bull crossbow almost outside the accurate range of the bow and arrow, they controlled the eight-bull crossbow to shoot an arrow.

Airplanes!

With the buzzing of the eight-bull crossbow, the crossbow arrows shot out like lightning.

Sou!

The bolts pierced through the walls of earth, even reaching deep into the ground.

This is the power of the eight-ox crossbow, which is usually a reinforced city wall, which can be nailed to it for soldiers to climb.

Gong Yipo looked at the earthen wall, there was nothing wrong, and then looked at the crossbow arrows inserted in the ground, and said speechlessly: "The power has really not been reduced!" What kind of pulley are you, what the hell is it? ”

Leng Feng took the key handed over by Wu Tian and threw it to Gong Yipo: "You won't see it yourself!" By the way, it has a self-destruct device, you wait...."

There was nothing to say, because Gong Chuan had already taken the key and opened the pulley, and the self-destruct device set up by Huang Fuming did not play a role in front of him at all.

This is the self-confidence of the Gongyi family, although the rhubarb crossbow is looked down upon, but when it comes to collusion or something, no one in the world dares to argue with their Gongyi family, after all, there is a word called "Banmen get an axe"!

Looking at the structure inside, Gong Yi Po was a little obsessed for a while, they were all wheels, but after being combined, they could exert such an effect, which was similar to the knowledge of their family's gear combination to increase their strength, but there seemed to be a little difference.

"Fan Shen, help me pull the crossbow string."

Fan Shen agreed, and pulled the crossbow string.

Looking at the operation of the pulley, Gong Chuan let out a long sigh of relief.

This is a new knowledge, and this knowledge can be combined with his own home learning and applied to many places.

Thinking of this, Gong Yipo looked at Leng Feng in embarrassment.

I swept my own treasure, but people didn't mean to hide it at all, and opened the shell of the pulley block to let me see, this is everyone's anger!

"Well, Guogong, I didn't mean to spy on the pulley...."

Leng Feng shook his head: "It's not enough to watch, with your family learning, you must have similar knowledge." I guess you've already seen through the knowledge of pulleys by now, how about it? ”
