In March, in the north of Xianyang City and in the south of Jiuzhi Mountain, a towering building complex that is not inferior to Xianyang Palace rises from the ground.

Mo Yunyu grew his mouth and was amazed by this for a long time.

"It's gone." Wei Yi beside Ziying reminded.

"Huh?"

Mo Yunyu hurriedly lowered his head, and saw the sugar gourd rolling all over the ground, and his hands were also sticky, so he raised his hands in pain and licked them violently.

"It's a pity, it's a pity..."Mo Yunyu's face was full of regret, "The King of Qin can summon craftsmen to build a palace in a short time, why don't you send Qin Min to plant a large number of red claws, and save this thing from being so valuable." ”

"The King of Qin sent Your Excellency to use a powerful Qin Blade, if you have any gains, you can get this thing on the Qin land." Wei Yi said lightly.

"Alas, deal." Mo Yunyu had a fixed expression, "King Qin is really calculating, Chu Yue is already in a mess, and King Qin can build another palace if he has leisure." Come to think of it, the old guy is still mediating in it. Relying on the remoteness of the ancestral land, you can really wait for work. ”

"Less nonsense, this place was built for you." Ziying spoke.

"Down?!"

Mo Yunyu couldn't believe it, and seeing that Ziying was not joking, he rubbed his hands and pushed the door of the palace in.

To the left and right are the houses, and there is no main hall in front of them, just a few red cloth-wrapped objects in the open space.

Mo Yunyu stepped forward and carefully uncovered the red cloth, which was several cannons. "This thing is the strange weapon of King Qin attacking Zhai and blocking Wei? Hearing doesn't work wonders, it's just waste. Mo Yunyu groped.

Ziying nodded slightly, "This thing can break the city with one blow, but after a blow, it will take a long time before it can be used again, and it really doesn't seem to be as good as a catapult." When blocking Wei, the widow was not in Qindi, and the soldiers used this thing inappropriately, but it was like a waste. Therefore, the widow hopes that Your Excellency will transform this thing, and he will attack the city and pull out the village in the future. ”

Bell Bell –

Mo Yunyu leaned on the cannon and clapped his hands several times, "It's not that he doesn't help King Qin, but Mr. Lingyan only secretly teaches the art of sword making, although the sword can be sharpened like clay, but it has nothing to do with this thing." ”

"Your Excellency has not tried, how do you know that you can't?" Wei Yi frowned.

Ziying knew that Mo Yunyu's words were reasonable, and the tenacity of iron was not the same as heat resistance. For this place, Mo Yunyu is no different from ordinary craftsmen.

Mo Yunyu bit his lip tightly, his face seemed to be embarrassed, "King Qin doesn't know, although he also likes to lose, the Mo family's technique, but the thing in his heart is the wooden kite of the public loser." I have been thinking about the method of the wooden kite for a long time, but I haven't gotten it. Old... There is only one place that can help the King of Qin. ”

"The art of the wooden kite?" Wei Yi couldn't laugh and looked at Ziying, "If the King of Qin doesn't use the art of sword refining to strengthen the army, he can also fight the princes." Mo Chu could not travel to other countries, and he was by no means the enemy of the Qin people. ”

Ziying shook his head slightly, "The advantage of this kind of blade is too small, even if it wins, the Qin people are also damaged, and the enemy army is also unwilling." The widow wants to dominate the world with a sword, so that there is no opponent among the princes. The world originally belonged to Qin, and it should be taken easily, rather than being torn and taken by beasts. ”

"That's how it should be." Wei Yi comprehended the heart of the child, but now he was powerless to help, and he couldn't help but sigh.

"It seems that I have lived up to the high hopes of King Qin." Mo Yunyu looked around the house and saw that this place was built for craftsmen, and he also understood the urgency of the child to strengthen the blade.

"Not necessarily." Ziying was not discouraged, and said with a smile, "The technique of the male loser wooden kite seems unreasonable, but there is a way. If Mo Shaoxia is in trouble, he can ask the widow, and the widow can help. ”

"King Qin can help?!"

Mo Yunyu suddenly came to his senses, took out a folded silk cloth from his arms and put it on the barrel, pulled the cuffs of Ziying regardless of the etiquette, and pulled it aside.

Ziying raised his eyes and saw that on the silk cloth was a wooden kite structure drawn by Mo Yunyu's brush, and each piece of wood was A, B, C, D, Zi Chouyin, one, two, three, four... Numbered is marked. It is also written that when the wind is strong and the wind is small, how to replace the wood chips when the wings of the wooden kite are out...

"King Qin, please see, I made this thing in Xia and slid down the tower, and it was not far away. He once slid down on Mount Tai and almost broke his leg and died, but it was not far away, and he could not return to the home of Qi from Chu to Qi as he lost in the past. Does King Qin know the reason?! ”

Mo Yunyu's eyes were blazing, looking directly at Ziying, eager to get an answer from this monarch who had seen the heavens.

The moment the child looked at the picture, he had a headache. In addition to the force analysis on the picture, it is simply the most difficult topic for him at a certain reading stage.

"This..."

"King Qin can't either?" The light in Mo Yunyu's eyes gradually faded.

"No... There is a law for the outnumbered. Ziying endured the feeling of discomfort, "Bring the pen!" ”

Mo Yunyu didn't bring pen and ink with him, so he put the picture on the ground in a hurry, ran away quickly, and found a branch from nowhere to stuff it into Ziying's hand.

"King Qin, please advise!"

A king and a hero squatted on the ground, staring at the ground with four eyes, sketching and drawing. Wei Yi was also curious, and the three of them made it easy for the silk cloth to form a ball.

"The things that are on high shall fall, for they are... Gravity. "Ziying is a serious way.

"Heavy... Force? Mo Yunyu heard this for the first time in his life.

"Exactly." Ziying nodded again and again, "If the wooden kite wants to fly high and not fall, it must have another force to fight against gravity." ”

"King Qin's intention is to pull up top of the wooden kite?" Mo Yunyu guessed.

"That's not the case!" Ziying hurriedly cried out, "It should be fought by external forces, not internal forces!" ”

In Ziying's eyes, Mo Yunyu is himself after a thousand years...

"Internal forces, external forces..."

Wei Yi has lived for more than 100 years, and for the first time he feels that he is only a shallow learner. The "friction" and "power" in the mouth of the child and the baby... Hearing this, he unconsciously had a headache, and got up and stayed away from it, not wanting to listen again.

Mo Yunyu didn't understand at first, but gradually the light in his eyes returned, and he was thirsty for knowledge.

"King Qin's meaning is that the chariot does not move without horses, and the birds do not fly without wings. If you have the strength to do it, you can do it like you lost it back then?! Mo Yunyu clenched his fists and was excited.

"That's right." Ziying wiped fine sweat and was full of relief.

Wei Yu thought that the words of the two were over, and then he heard the "formula" and "theorem"... If it weren't for Ziying being the king, he wouldn't want to stay here for a moment.

"King Qin thinks he should overcome it with a joint force?" Mo Yunyu asked again.

Ziying held the branch and continued to sketch and draw, drawing the engine of the future generations with his memory, "Mo Shaoxia can boil water in wood, and after the water is boiled, he will drive this thing with his strength." This thing then drives the foreign object... In short, the wooden kite can be obtained, and Mo Shaoxia might as well try a horseless car first. ”

"With the help of King Qin, this matter will be done!" Mo Yunyu arched his hand, already grateful.

Ziying explained a few rounds in his ear, and the two finally got up.

Seeing this, Wei Yu waved his hand behind him, and the Qin disciples, who had been waiting for a long time, guarded around the new palace according to the prior explanation.

"From today on, this place will be handed over to Mo Shaoxia. If there is a need, although it can make the soldiers go to Xianyang, the widow will respond to his needs. Ziying smiled with relief.

"Thank you Qin... Your Majesty! ”

Mo Yunyu has no heart to be a king in his chest, and he seems to have a more valuable goal to go to.

Without waiting for the two children to leave, he ordered the Qin disciple to chop wood and boil water.
