"This thing ......"

As soon as the two words came out, Huang Shisan had already laughed. Yu Shan frowned, and Su Ren glared at Huang Shisan, but it didn't work. Su Ren was a little embarrassed, and said to Shan: "The king doesn't need to **** me with these novel things, I have already thought of a way, although it is said that it cannot feed all the victims, at least the consumption on the road will be much less, that is to say, Shan Yu will have more food to help his people." ”

"Seriously!" Yu Shan couldn't care about any colorful stones anymore, his face was full of joy, tears were about to flow out, and he dragged Su Ren into the tent.

Su Ren sat down, took a sip of tea first, and said under the urging of Yu Dan: "The way I think is actually nothing, just changing the carriage, originally a horse can pull five hundred catties, but now it can pull two thousand catties, so there is less transportation costs." ”

"Brother Su, please talk about it in detail!" Yu Shan excitedly moved towards Su Ren.

Su Ren took a branch and said while drawing on the ground: "I have seen that the carriages we originally used were all two-wheeled, and when the livestock pulled the cart, they also had to carry the weight of some of the goods, and it was very difficult to pull the heavy objects, so I thought about adding two more wheels, so that the livestock only needed to pull forward, and it would save effort, and naturally it would pull more." ”

Yu Shan looked at the sketch drawn by Su Ren: "In other words, this kind of carriage can be built very large, as long as the horse can pull it." ”

Throwing the branches, Su Ren nodded with a smile: "Theoretically, this is the case, but you also have to consider the bearing capacity of the vehicle, if it is too big, the goods will be loaded too much, and you will crush yourself, how to pull things." ”

Yu Dan's face turned red with excitement, his two eyes kept staring at the painting drawn by Su Ren, and he got up after a long time: "Okay, Brother Su's method is good, I'll go and sue Father Khan now!" ”

Su Ren hurriedly grabbed Yu Dan: "The king is slow, there is something to say next!" If this thing can solve the problem, why don't we make more use of it? I will declare to Shan Yu that I am responsible for the transportation, so the price of grain can only be a horse for a month's grain, and then I will subcontract the transportation to the king, hehehe, the king understands? ”

"What do you mean by Brother Su......?"

Su Ren smiled: "The price of grain I gave to the king is a horse for two and a half months of grain, which saves one and a half months, the king accounts for one month, and I have half a month's profit, what does the king think?" ”

Yu Shan began to settle accounts in his mind, and after a long time, a smile suddenly appeared on his face: "That is to say, I will transport two months' rations for one person from you, only give you one horse, and then send half of the grain here to exchange for a horse from my father Khan?" ”

Su Ren nodded slightly. It seems that this is a benefit for both parties, but in fact, Su Ren wants to minimize the risk. It is a full two thousand miles from Mayi to Wolf Juxu Mountain, who knows what will happen on the road, and it will be much safer to Yuci. As long as he keeps sending grain to Yuci and getting horses from Yu Dan, as for whether Yu Dan can deliver grain or whether he can get horses from Shan Yu, it is not his concern.

Yu Shan was very happy, the whole person came alive, and he said flattering words to Su Ren, and he couldn't wait to give credit to Shan Yu now. Seeing Yu Dan flying on the horse like a child, Su Ren grabbed it and said with a smile: "Be careful, tell me one more thing, that colorful stone is not worth two horses, not even a horse ear, because he was made by me." ”
