Teng Cangkong nodded: "This is the principle of leverage, which is easy to understand." ”

"How leverage works?"

"Before, that guy Wu took a stick and gestured it in front of me, what a lever, but in my opinion, it was just a crowbar that even the shepherd knew to use, and I also scoffed at it. Lao Wu also laughed at people like me for not being able to innovate, and they only knew everything but didn't know why, but now it seems that he is really right.

Crowbars are everywhere and can be used by anyone, but who has ever thought about the truth behind them? ”

"Then what is the reason between you and me?"

"This is ......" Teng Cangkong just opened his mouth, as if the words were on his lips, but when he was about to find that he didn't come out, this is like many people who think they know, but when they really want to tell the truth, they find that they don't know anything at all.

"What's wrong, Mr. Teng?"

"I ...... I forgot to ask. I forgot to ask Wu Zheng what the hell is going on, he only has a crowbar to save effort, this is the truth that everyone knows, but no one uses this thing to make stone cannons! And Your Highness, you see, the stone cannon painted on this picture is clearly to drop heavy objects to the ground to throw light objects, which is also contrary to his labor-saving theory! ”

Mazan was stunned for a moment, and subconsciously looked at Wu Zheng's camp tent, outside the camp Qiao was alone with a stick carrying the bonfire, and turned back to Teng Cangkong and said, "Now go and ask him if he is still in time?" ”

"Now? Not good! ”

Ma Zan smiled, how cheap the smile is, and after laughing, he said with a straight face: "It's already very good that we can get the pattern of the stone-throwing cart from Wu Zheng's hands, and it's a bit too much to know the principle." But I still have a little bit to figure out, since this thing is called a rock-throwing car, it has to be a stone, otherwise what is it thrown? ”

Mazan looked at Teng Cangkong in puzzlement, because Mazan also knew that there were no stones on this grassland, and could a stone-throwing car without stones still be called a stone-throwing car?

Lao Teng also wondered! That's right! Although Wu Zheng has built a new type of stone-throwing car, there are no stones on this grassland, how should he use this stone-throwing car?

Lao Teng was silent for a moment and said, "I think we can ask about this." ”

Second, Wu Zheng finally decided to pull out the camp and go to Xiangri Ridge, Wu Zheng set off, that is, Ye Dongcheng's really walked to Xiangri Ridge according to Wu Zheng's plan.

Along the way, Mazan wanted to get close to Wu Zheng and ask him about the cannonballs of the catapult, but he never had the opportunity, because Yin Cao, the beautiful woman in his eyes was always tired of Wu Zheng's side, and even sometimes shared a horse with him, when did the woman in the Central Plains become so open, so many people around and so many pairs of eyes watched! Not afraid of immorality?

Think about it! As long as he blushes when he sees Yin Cao, he can't find a chance to ask Wu Zheng for advice!

"Hey! Do you think the latter one is interesting? Yin Cao leaned on Wu Zheng's arms and said with a teasing smile.

"Which one?" Wu Zheng said curiously.

"It's the piece of waste that lies down and is carried away!"

"You're Mazan? People are the prince of Tuyuhun, how dare you be a waste? ”

"What's wrong with the prince, it's a waste that refuses to even walk."

Wu Zheng said with a smile: "You have wronged the dead family, he was beaten like this by Ye Dongcheng." To be more precise, he was bombarded by my 98k, how many people can there be in the world where my 98k escaped with his life, and you are still a waste, and he is not angry when he hears it. ”

"In that case, let's not go to Xiangri Ridge to see the excitement!"

"Don't worry, that guy only has one bullet left in his hand right now."

"A single bullet can kill you! Listen to me, let's camp here, and let the people under us do the killing of Ye Dongcheng, why should we as masters take such a risk, it's not worth it. ”

"I want to too! But if I don't see him die with my own eyes, I'm still not at ease! Well, go ride your own horse! That guy has already turned around nine times in front of us, and must be looking for something for me. ”

Yin Cao reluctantly jumped on his war horse, Qiao saw that Yin Cao was no longer tired of Wu Zheng, so he hurriedly hugged Luan Yin and came over, the three women didn't know what to do, where the chatter was a bit like going to war, more like the sister of the big lord of the high gate going out on an autumn outing.

"Looking for me?" When Mazan passed in front of Wu Zheng's eyes again, Wu Zheng said.

Mazan hurriedly nodded, propped himself up from the stretcher, and said, "I still can't figure out one thing about that Brother Wu, and I ask Brother Wu to give me advice." ”

"I can't see that you guys can still be so literate, do you want to ask how this stone-throwing cart has cannonballs?"

Ma Zan smiled, then nodded and said, "I really can't hide anything from Brother Wu!" ”

Wu Zheng pointed to the ground and said with a smile: "There are no stones, but you see that there is a lot of soil here!" If we can't fight the stone cannon, we can't shoot the earth cannon? ”

"Earth cannons? Can you smash people to death with such loose soil? Brother Wu, you're kidding! ”

Wu Zheng smiled: "No kidding, let me ask you if you can smash people to death in the wine jar?" ”

Mazan nodded, and Wu Zheng said again: "What are the nine jars made of?" ”

"Uh...... I see! The reason is very simple, Mazan is not stupid, and he can understand it naturally, so he smiled: "Wu Zheng, how did your head grow?" How is it that there is nothing in this world that can make it difficult for you? ”

"You can't be interested in my head, are you?"

"Don't be stupid, I don't have that guts, but when I think that you are going to leave after killing Ye Dongcheng, I really still have something to do."

"That's it! Why don't I take you with me when I leave? ”

Ma Zan was stunned for a moment and asked, "Brother Wu, this kind of joke can't be messed around." ”

Wu Zheng smiled slightly: "Are we friends?" ”

Mazan thought for a moment and said seriously: "I don't have many friends, but you are definitely one." ”

"Then an old friend is going to travel far away, and it is always appropriate to give a ride as a friend!"

"That's natural, but it takes a farewell to send you a thousand miles in the end, and I won't agree to send it home."

"Don't worry, it's not like I can't find my way home, Tongyang Pass! How about sending it to Tongyang Pass? ”

Ma Zan nodded, and seemed to have no intention of chatting with Wu Zheng again, so he waved his hand and asked someone to carry him to the back of the team.

Xiangri Ridge is not far away, even if Wu Zheng marches like this, he will arrive at the two.

There are many mountains and forests like Lao Teng, and they are all dense pine forests, which are rare in this land in the northwest. Ye Dongcheng was forced to walk towards the Riling Mountains, and naturally he would not take people to the pine forests with high mountains and dense forests, so the valley under the mountain where the grass and yellow warblers flew was undoubtedly his best choice.

In view of Songchuan's previous experience, Ye Dongcheng first asked Qianqi to open the way when he came over, and then he still felt a little uneasy, so he simply set a fire and burned everything that could be burned in the valley first, and then he took the six thousand light horsemen with his heart on the road...... 166 Reading Network
