Now, the only question is how much damage this stone has caused to the mountain, and whether it has changed compared to what they have excavated, this is what Lu Jia really cares about, if the strength of the smash is similar to that of not smashing, then these two trebuchets will be a bit of a chicken rib, and in the end they may have to rely on manpower to solve this matter.

"General, you and I will take a closer look!"

Seeing the rolling dust coming out after the stone smashed into the mountain, Lu Jia couldn't stand anymore, he greeted Han Xin, and then walked towards the mountain by himself, although Han Xin was also very curious, but he was thinking in his heart before like some of the soldiers under his command, that is, if he could take these two trebuchets to attack the Peacock Dynasty, if that is the case, this stone will go down, and the pressure on the army of the Peacock Dynasty will definitely be quite large.

When Lu Jia walked to the place where the stone had been hit to check, his originally tight face finally showed a smile that he hadn't seen for a long time.

"General, with this thing, this mountain is broken, it must be just around the corner!"

After staying here for more than a month, Lu Jia didn't know how many times he had studied what was going on in this mountain, and now that he was able to say such a thing, Han Xin naturally believed it.

Of course, this is thanks to Zhang Kai, who is far away in Xianyang City, Lu Jia knows that this exploration, the craftsmen sent by Zhang Kai have played a very huge role, plus these two trebuchets, in the end, if you talk about credit, Zhang Kai is afraid that he will be a little bigger than himself.

Han Xin followed, only to see that the stone they had chosen to hit the mountain had been smashed by the mountain, but the originally solid mountain had also been hit and a lot of things were scattered and dropped by the impact, just at this moment, the effect was basically the same as the effect they had been digging for several days, which meant that these two instruments had been throwing stones for one day, which was equivalent to the credit of these people digging for more than ten days.

Seeing this situation, Han Xin also breathed a sigh of relief, what he was most afraid of was that this thing was not easy to use, and then his 20,000 elite soldiers who originally planned to give the people of the Peacock Dynasty would have to dig mountains in this gang of Lu Jia, in Han Xin's opinion, it was really a bit overkill to let the most elite cavalry of Great Qin dig mountains here, instead of killing the enemy.

Now in this way, Han Xin's 20,000 people are obviously liberated, and he can take these 20,000 people to train some tactical things in such a bad situation.

He has his own plans, and when he arrives in the territory of the Mauryan Dynasty, if there is any opportunity, he will definitely act alone with the 20,000 army, so the 20,000 cavalry must have a very strong survivability.

Han Xin just wanted Xiang Yu to know that although he only had 20,000 horses, in terms of ability, he was definitely no worse than his 80,000 Hun cavalry.

He has been holding his breath in his heart since he first led the horse for Xiang Yu, although now Daqin and Xiang Yu have signed an alliance, but Han Xin doesn't care about that, he just wants to prove his ability in front of Xiang Yu, maybe now it is a matter of right and wrong, even if he proves that he is the first good general of Daqin, Xiang Yu will not feel anything, but this matter is very important in Han Xin's heart.

After saying hello to Lu Jia, Han Xin took care of himself to find a place to train his troops, with these two treasures, Lu Jia naturally would not let Han Xin help him dig the mountain in vain, and he also knew that these 20,000 people were going to march towards the Peacock Dynasty with the Huns, which was fueled by the prestige of Great Qin, so at that time, he couldn't be tired before the war.

At such a happy moment, Lu Jia naturally did not forget Yinggao, he wrote a letter at that time, informing Yinggao that these two instruments really played a great role in what they were doing now, and told Yinggao According to his previous prediction, with these two equipment, it should be possible to open up the mountain within the specified time.

In fact, Yinggao really didn't wait for their news in Xianyang City as Lu Jia imagined, what kind of power that weapon had, Yinggao had already seen it, so he wasn't worried about it, and now he was thinking about another thing.

By using only three days to build that kind of stone throwing car, Yinggao later thought about it and found that there were many irregularities in it, only three days, why did Zhang Kai design and manufacture such fine parts?

Although Yinggao did not say anything about the design of the opening of the scarf, but in the stone thrower, the principles of various levers and some other mechanical principles that were more advanced in later generations were applied by the opening very skillfully, if this could really be built in three days, the opening would be a more famous physicist than Newton.

And with this question, Yinggao also asked Cao Shen to help him understand Zhang Kai's background a little again, and this understanding, Ying Gao had it in his heart, so on a sunny morning, Ying Gao came to Zhang Kai's mansion after eating.

Zhang Kai's mansion, Yinggao is also a serious first time, and now, Zhang Kai, who has been living in Xianyang City for several years, has already married a wife and had children in Xianyang City, and his small life is quite happy, and there are also a few servants in the courtyard who are busy working, of course, even so, in Zhang Kai's official position, he is also very simple.

This period of time is a rare leisure time for Zhang Kai, and when there is no court, he is mostly in the mansion to accompany his three- or four-year-old tiger-headed son.

When Yinggao arrived, Zhang Kaizheng was holding a bunch of small objects made by himself, teasing his son and laughing, he looked up suddenly, but saw Yinggao smiling and smiling into the courtyard of his house, at that time he couldn't care about anything else, and knelt directly on the ground and saluted Yinggao.

The son obviously didn't know what his father was doing, but he probably thought it was funny, so he threw down the gadgets in his hand and knelt on the ground like his father......

"You really have a good way to teach your son, I just passed by your mansion today, so I came to take a look, don't be so restrained, get up quickly."

Zhang Kai has always been upright, listening to Yinggao say this, and then looking up, sure enough, Yinggao was only followed by two guards in civilian clothes, obviously just wandering on the street, so he got up, and then hugged his son, who was still smiling and kneeling in his arms, who didn't know what was going on, and beckoned his wife to take the child away.

"I don't know what happened when you went up to the open mansion? The house is simple, and I really don't know how to entertain the king. ”

What Zhang Kai said was true, there was nothing in the emperor's Xianyang Palace, and now that he was in the mansion of an ordinary official in the court, of course he wouldn't play.

"Since I'm here, naturally I can't just leave, you and I can sit in your study for a while."

Hearing Yinggao say this, Zhang Kai didn't think of anything else, but led the way directly in front and led Yinggao into his study.

Entering the open study, Yinggao found that his study, which was really a real study, was full of bamboo slips and some drawings rolled into a roll, and Yinggao had a vision, and at a glance these things knew that it had been some years, in this era, these things can be called old objects.

Yinggao's habit has always been straight to the point, and the reason why he didn't say anything useful when he was in the courtyard was just because he was afraid that the partition wall in the mansion of such a trusted official would have ears.

So Ying Gao picked up a roll of bamboo slips casually, and asked casually: "I'm afraid that the books in your room are priceless, is the stone-throwing cart you designed in three days last also from these scrolls?" ”

After Ying Gao finished asking this sentence, he raised his eyebrows and looked at Zhang Kai, obviously there was something else in this sentence.

Although Zhang Kai is upright, he is also a veteran who has been exercising in Daqin's court for several years, although he does not participate in any arguments on weekdays, and is dedicated to managing his own one-third of an acre, but he has always mastered the direction of the wind in the court very accurately, and he is by no means a person who can't see the height of his eyebrows.

"What do you mean, Your Majesty?"

"What do I mean, my Daqin can have a talent like you, it is really Daqin's luck, it is my luck! Above my Great Qin Dynasty, there has always been a situation of a hundred schools of thought, but there are some schools of thought that have not had decent talents because of the wars in recent years, including the Mo family, I don't know if you think so? ”

When he asked this sentence, Yinggao's eyes were a little sharp, which made him know what was going on when he opened his eyes, and a layer of fine beads of sweat appeared on his dark cheeks, and then he quickly knelt on the ground, as if after a period of ideological struggle, he finally said a sentence.

"Before opening up, he did hide something from the king, and asked the king to surrender!"

Zhang Kai is indeed a person who does not hide anything, and when he saw Yinggao, he seemed to have discovered something, and he confessed his sin at that time. He knows that there is such a rule in Qin Law, you lie to your parents, that is your freedom, although Qin Law does not advocate it, but if you do that, he can't do it.

But if you lie to the emperor, or deliberately conceal something from Zhang Kai, then this sin is great, and if you say that you are dead, you will die, of course, whether it is a deception or not, it is based on the emperor's words, so this article is still very dialectical.

"If you say it now, it won't be a concealment, so why should I condemn you? Let's start with whether the two pieces of equipment sent to the Wasteland were something you came up with on your own in those three days! ”

Yinggao's words are obviously equivalent to giving Zhang Kai a chance, Zhang Kai can naturally hear it, and according to his original thoughts, his true origin is actually not worth hiding, but he didn't tell him at the first time when he took refuge in Yinggao, so he always felt that it was not interesting to tell him later, so it has been delayed until now, of course, there are other reasons for this.

"This thing...... It's true that Zhang Kai came up with it, but Zhang Kai had seen the design of this thing in a classic book before, and that day he saw that the king was eager, so he went back to the mansion to rummage, and after finding it, he felt that it was indeed a feasible thing, so he made it..."

"These are all trivial matters, let me ask you, after you arrived in my Great Qin Dynasty, you only made objects, but never participated in the discussion of court politics and war, is it related to the fact that you are a member of the Mohist school?"

"Huh? Your Majesty, you have already learned about this? ”

"Hmph, if not, how long do you want to hide it, just at the stone-throwing cart you made, I can see some clues, do you really have been wasting time in Xianyang City in the early years? Compared with the stone-throwing trucks used in various countries, the stone-throwing car has a lot more processes, especially the lever has been widely used in it. ”

"This..."For a while, Zhang Kai really had nothing to justify, he was not a person who could speak well, and now he was pierced by Yinggao The secret in his heart was pierced, and he didn't know what to say in his mouth.

"If other schools had mastered the technology of this stone thrower, I am afraid that it would have been applied to the previous wars of various countries, but only the Mo family, what you advocate is both love and non-attack, in your eyes, I am afraid that it has only reached half of it, so for me, you should be very entangled."

After Yinggao said this, he opened his mouth wide, because what Yinggao said almost accurately hit what he thought.

"Your Majesty, Zhang Kai is indeed as you said, he is a descendant of the Mo school, he is not guilty, he is guilty, the Mo family has a lot of research on some organs, so it was hunted down by many countries in the late Warring States period, what they did, is it not these objects in Zhang Kai's study? Some of the elders of the Zhang Kai clan were slaughtered because of this incident, and Zhang Kai had to do it as a last resort when he fell into the grass in Chen County, and these classics were hidden in a hidden place by me at that time, and it was not until later that he followed the king to Xianyang City, and he dared to send someone to take them out. ”
