The pen and ink are used. ”

"Chu Aiqing, please!"

Chu Ze walked over and picked up the pen, drew a few strokes, and a simple drawing of a small cart appeared on the paper.

"Chu Aiqing, what is this?" His Majesty Li Er looked down and asked.

Chu Ze put down the brush and stone, and after the ink was dry, he smoothed the paper, moved his arm and said, "This thing is called a trolley!" As long as one person can carry the goods that a horse can carry! ”

"Can one man top a horse?!" His Majesty Li Er was shocked, if someone else said this to him, he would definitely think that this person was farting, but it was Chu Ze who said, it would definitely not be untargeted!

His Majesty Li Er was surprised and delighted in his heart, and grabbed Chu Ze and said, "Where is this thing now?" ”

"Your Majesty, don't worry, this is a sketch of the wheelbarrow, there must be a lot of skilled craftsmen in the palace, it won't take too much time, I believe Your Majesty will be able to see the real thing."

His Majesty Li Er hurriedly instructed the attendants beside him: "Quickly go and gather the best craftsmen in the palace to wait outside the palace!" Prepare to listen to Chu Aiqing's orders! ”

After a while, there was already a circle of craftsmen outside the Taiji Palace, Chu Ze didn't deal with craftsmen once or twice, in fact, in Chu Ze's heart, he felt that these craftsmen were the most respected, after all, the laborers were the most glorious!

Chu Ze followed His Majesty Li Er and everyone to the outside of the Taiji Hall, and Chu Ze first recalled the basic structure of the trolley in his mind. In later generations, this thing was really not less touched, and when it came to flood fighting, bags of sandbags were all pushed by this trolley.

It's nothing more than a wheel and a frame! There is no need to think about the iron frame, there is no steel pipe here, and there is no high-end goods such as electric welding. But luckily there's wood, and it's a lot of good wood! Tell the carpenter to find the tough and strong wood, and throw him the drawings of the frame, and tell him that he will see the finished product in an hour.

Chu Ze then led the blacksmith to make the only bearing in the trolley that was a little difficult, but it was not too troublesome, and the existing conditions could be made with a little effort.

Use good iron to cast into a solid small iron ball, and then quickly polish it to the general size, two round kits one throw into the ice cubes, the other with carbon fire until red, take advantage of the thermal expansion and cold contraction of the gap is large enough, the iron balls are stuffed into one by one, and then wait for them to return to normal temperature, the iron balls have been firmly embedded in the small slide inside, no matter how they turn, they will not fall out again.
