Looking at Yu Guangdao's emotional performance, Han Qin, who was still sluggish just now, didn't collapse, almost didn't squirt, and hurriedly covered his mouth and lowered his head.

And Qi Heng on the side also swallowed dryly, his eyes warned Han Qin beside him, and hurriedly said: "Mr. Yu is serious, how can Qi Heng be virtuous." ”

As he spoke, in order to avoid embarrassment, he hurriedly picked up a glass of wine and said, "Come, Mr. Yu, let's have a drink together." ”

After a glass of wine, Yu Guangdao was even more excited.

As he spoke, he began to undress.

This scene frightened Qi Heng and the others.

After all, everyone has seen how demonic this person is, and they are in a hurry to stop it.

But Yu Guangdao ignored everyone's obstruction, and directly took off his coat and threw it away.

Just when Qi Heng felt that the wine was 'full of demonic spirit' tonight, Yu Guangdao on the opposite side took off a close-fitting underwear and handed it to him.

"My lord, please accept it!"

"Mr. Yu, this.... Not really, right? Qi Heng said confusedly.

In the past, I only heard of ancient men and women sending love tokens to each other, and I really haven't seen this kind of taking off underwear and giving it away.

Feeling the strange gaze of Qi Heng and others, Yu Guangdao seemed to suddenly want to understand something, patted his head, and said, "Look at me, don't blame me, my lord, I'm reckless." ”

Saying that, Yu Guangdao turned his underwear inside and out on a cold day.

I saw that the reverse side of the underwear turned out to be an unknown piece of leather, which was completely different from the white fabric outside.

At the same time, there are some dense patterns painted on the skin.

Qi Heng, who saw this scene, frowned and took a look.

There was a gleam in his eyes.

Yu Guangdao, who was on the other side, looked at Qi Heng's gaze and said, "My lord, my Yu inheritance has been more than a hundred years now, and I was a craftsman in the palace during the Song Dynasty, specializing in the development of bow and crossbow chariots for the army. ”

"It's a pity that after the Song Dynasty was destroyed by Hu Yuan, my grandfather and grandfather's generation were not taken seriously, but this income was not lost, in order to develop new bow and crossbow weapons, I don't know how much money was spent in the past hundred years, and finally in the hands of my grandfather and father, a more powerful ballista was successfully developed!"

"When my father died, he suddenly fell seriously ill, and before he died, he gave me this picture as a family heirloom, and he could only give it when he met the master."

"This ballista, the crossbow arrow can shoot up to 1300 meters, but after more than 1000 meters, the power will be much worse, my father once said that it is best to be within 800 meters, the most powerful."

"But distance is not the advantage of ballistas, the ballista designed by my father can shoot twenty crossbow arrows at a time!"

"And according to my father's experiment, I can complete the second round of shooting in just ten breaths."

While listening to Yu Guangdao's explanation, Qi Heng looked at the diagram in his hand.

Although these patterns are very simple, Qi Heng can still see a rough idea.

The ballista in the mouth of this afterglow road is equipped with arrow boxes on both sides according to the way of Zhuge repeater, and once it is fired, it can automatically scroll down when the pry mechanism is turned to achieve the effect of reloading.

However, unlike the Zhuge Repeater, which had to redraw the bow after firing an arrow, it used a precise curved arc to achieve the effect of winding twenty crossbow arrows at the same time.

And you only need to turn the wheel on one side to complete it.

In other words, before the crossbow arrows in the quiver are exhausted, each shot only needs to be wound with ten breaths to turn the wooden wheel.

Even Qi Heng, who is a modern person, has never seen such a miraculous workmanship!

It is worthy of being a killing weapon developed by a famous craftsman of the previous dynasty for several generations!

Qi Heng really didn't understand why such a miraculous killing weapon did not appear in the history of later generations.

This thing, on today's battlefield, is simply a strategic-level deterrent!

I want to make a dozen of them on the battlefield, and I also interspersed them with tactics and covered them with direct firepower.

Of course, there are limitations.

The range is the disadvantage of this big killing weapon, and the bed crossbow is a weapon that has been around for a long time in ancient times, and the maximum range should be around 1500 meters.

In comparison, the ballista is slightly weaker at 800 to 1000 meters.

However, the bed crossbow is only a single shot, and the power between the two is not the same.

In addition, the ballista will be very large in terms of pattern.

Without improvement, it is almost impossible to use it in the field.

However, if the city is defended, the power of this ballista will be fully displayed.

According to the range of a normal manpower bow and arrow, 300 meters is basically the limit.

However, it has a maximum power range of 800 meters, and once the number develops.......

Thinking of this, even Qi Heng, who had seen modern weapons, couldn't help but be amazed.

However, Qi Heng didn't get excited too early, he hurriedly asked Yu Guangdao, "Is there a real thing that has been created now?" ”

Hearing this, Yu Guangdao said helplessly: "My father is just an ordinary craftsman, and such a large object really doesn't dare to be exposed to outsiders at will, so it was dismantled after the test. ”

"Today...... There are no physical objects yet. ”

When Qi Heng heard this, although he was a little disappointed, he was not in a hurry: "Then you may create this thing?" ”

Yu Guangdao said embarrassedly: "I only like to read since I was a child, and I didn't learn these things from my father, and the craftsmanship of the family is lost when it comes to me....."

Qi Heng nodded, not too disappointed, after all, this design is in his own hands, even if it is not so easy to remake it, but it is not too much of a problem to take a moment to think about it.

It's just that if there are things, it can save a lot of trouble.

After all, not all things can be memorized.

Just as Qi Heng was about to say something, Yu Guangdao suddenly said: "However, my lord, the parts of my father after dismantling are still buried in a cave outside the city, if you go to find it, it should still be there." ”

"Really?!"

Yu Guangdao nodded.

Qi Heng suddenly burst out laughing.

"Good!"

"Come on, go find Shen Wansan for me!"

As a soldier outside the house left, Qi Heng immediately said, "Mr. Yu, my uncle and his ancestors are really gods and ghosts, and they can design such a killing weapon!" In this picture, Qi Heng is like an army! ”

Speaking of excitement, Qi Heng was even more crazy than Yu Guangdao just now.

Although Han Qin on the side was also from the army, he didn't realize the horror of this thing at all.

That Zheng Guangzu stood there and listened stupidly.

Only Qi Heng was ecstatic in the field, making the two people on the side unpredictable.

Even this Zheng Guangzu quietly took two steps away from Qi Heng and Yu Guangdao, as if he was afraid of being infected by this "demonic energy".

With Shen Wansan's arrival, Qi Heng looked at him with a solemn expression and said, "Find a few craftsmen in the city, remember, you must know the root and absolutely trust the people." ”

As he spoke, he handed over the underwear in his hand to Shen Wansande, and continued to instruct: "Remember, no one can see this picture except you, and all the craftsmen who have seen this picture, I don't care whether you are detaining their family members or sending troops to monitor them, you must not leak the slightest rumor." ”
