The strongest engineering student in ancient times

In the afternoon, in Zhao Sanhu's yard.

Zhao Sanhu looked at Tie Xinmu who was dragged by Qi Yibai in shock.

He didn't quite believe what he saw, the iron heart tree was really cut down, how much effort would it take, and he couldn't guess what kind of knife could cut the iron heart tree down.

Aunt Zhao also watched in amazement.

Qi Yibai took out the grass juice he prepared this morning and said:

"Uncle Zhao, when you want to plan wood, just spray some of this potion on your blade, and it will easily move the iron heart wood. Spray some more when you can't plan. Ask me for it."

When Aunt Zhao saw the exquisite perfume bottle Qi Yibai took out, she had a strong love in her eyes. She had never seen such a beautiful thing, and she didn't know what it was made of, and where she could buy it. After all, as a woman, There is a natural love for exquisite small objects.

Uncle Zhao just thought it was strange that he had never seen the perfume bottle before, so he sprayed some on the saw as Qi Yibai said.

Aunt Zhao was even more surprised when she smelled the fragrance. She couldn't help sighing:

"It smells like powder, is this made from powder and rouge in water?"

Qi Yibai choked for a moment, seeing Aunt Zhao's eyes full of liking, he said:

"Aunt Zhao is really smart. If Aunt Zhao likes this taste, I will make another bottle for you next time."

Aunt Zhao really couldn't refuse such a good smell, so she gave Qi Yibai the wild boar bacon that Wei Qing had given to her earlier.

When they were talking, Uncle Zhao couldn't wait to try to saw hard on the iron heart wood, and the saw fell into a third easily.

Uncle Zhao cried out in surprise, shaking his mouth excitedly and saying incoherently:

"Saw it, I saw the iron heart wood, I saw it, can it really be sawed?!"

Uncle Zhao couldn't be more surprised, he wouldn't be the first carpenter who can plan the iron heart wood, right? !

Thinking of this, Uncle Zhao immediately became motivated, took Qi Yibai's re-drawn parts diagram, and started to make parts excitedly.

After Qi Yibai finally left with the bacon, he was not in a hurry to find Wei Qing, but returned home and flipped through the bicycle theory book in the system backpack.

In fact, it is not difficult after reading it. The introduction in the book is very detailed. There is also a model diagram of the bicycle on it. The introduction and calculation of each required part are included. Only the gearing needs to be calculated accurately, otherwise it will be against the chain. Not on, otherwise it is easy to cause off-chain.

Qi Yibai spent another fifteen system coins to buy a tool for drawing drawings and a large stack of A2A3A4 paper. According to the model of the chain, he quickly calculated it using the formula.

After that is drawing, he didn't want to be beautiful, the most important thing is to design light, simple and practical without too much burden.

For the sake of practicality, he designed a basket on the front of the car. After thinking about it for a long time, he added an auxiliary seat. After all, it can sometimes be used to carry some heavy objects.

After he spent an afternoon and a night designing it, and after confirming that there were no mistakes, he couldn't wait to put it in the forging room, only to realize that he had given the iron heart wood to Zhao Sanhu.

He had no choice but to plan to cut some iron heart wood early tomorrow.

The bicycle wheel is made of wood. When he designed it, he bought a corresponding type of shock absorber ring from the system, which can reduce the bumpy feeling. The seat cushion is going to be covered with cotton after it is made.

In fact, the parts he designed can be bought in the system mall, but unfortunately it costs too much system currency, so it is more cost-effective to prepare the materials yourself.

The next day, Qi Yibai went up the mountain early in the morning with a hatchet.

He found several iron heart trees surrounded by one person near the place where he cut them last time, and cut them down. Many of them were intended to be used to make bows and crossbows, while some iron heart trees only had thick legs, so they were not cut.

Qi Yibai discovered a very interesting phenomenon, as long as there is iron heart wood, the grass that softens the iron heart wood will grow.

Seeing that it is autumn now, I don't know when the grass will wither, so I simply cut off all the grass that can be cut and put it in my backpack for storage.

When Qi Yibai cut them all and planned to put them in the backpack, he heard movement behind him.

Qi Yibai was so frightened that he turned his head immediately, only to see Wei Qing holding a bow and arrow estimated to be 1.5 meters long in his hand, and two rabbits and a pheasant hanging from his waist.

Seeing him, Qi Yibai heaved a sigh of relief, thinking of that kind of grass, he immediately said:

"I didn't expect to meet you so coincidentally. I went to look for you yesterday, but you were not here. I just wanted to discuss this grass with you."

Wei Qing glanced at the weeds that had been cut down under his feet, expressionless, and asked:

"what's up?"

Qi Yibai immediately said what he was thinking.

As long as they process this grass into potion and sell it, the price is not up to them, and they can even grow it by themselves.

Wei Qing shook his head without hesitation when he heard it:

"Can't sell."

Qi Yibai couldn't be more surprised:

"why?"

Wei Qing shook his head and said:

"I don't know, but my intuition tells me that it will be dangerous if it is sold."

And it's at stake with his life.

Qi Yibai thought, by the way, this is not in his original world, he is a villager with no power, if someone is jealous, maybe he will be arrested and tortured to extract a confession.

Qi Yibai secretly rejoiced that he had told Wei Qing, otherwise his life would be over if he was not careful.

Because Wei Qing was here, Qi Yibai couldn't put the grass in his backpack, so he had to untie his belt, take off his shirt and prepare to wrap it up and take it away.

"what are you doing!"

He had just taken off his clothes when he heard Wei Qing's louder than usual scolding.

Qi Yibai looked at Wei Qing suspiciously, Wei Qing stared closely at his thin upper body, suddenly turned around as if shocked and said:

"Put on your clothes! If you want me to marry you, I'll ask a matchmaker to come to your house and say goodbye. You don't need to do this!"

Qi Yibai was stunned, what did he do?marry him?say kiss?

Qi Yibai's face suddenly changed, how could he forget that now he is a twin, equivalent to a woman.

And he undressed in front of Wei Qing, just like a woman undressed in front of him.

Qi Yibai almost petrified as if struck by lightning, quickly put on his shirt and explained:

"Don't get me wrong, I really mean something! I forgot to bring the bamboo basket, and I want to wrap all the grass back with my clothes!"

Conscience of heaven and earth, he absolutely did not intend to seduce Wei Qing or anything!

Wei Qing didn't turn his head all the time, but just said "hmm" with no emotion:

"I will pack my clothes for you."

Wei Qing took off his clothes, revealing his strong and thin muscles, Qi Yibai stared at him instantly.

Look at the smooth lines of the back, look at the wide back and narrow waist, there is no ugly fat at all, if this figure is posted on his Moments, see if those ugly people who are desperate to show their figures have no shame photo.

Although Wei Qing didn't turn his head back, he could feel a pair of scorching eyes staring at him closely from behind. Although there was no special expression on his face, the beating of his chest was slightly accelerated uncontrollably, as if he couldn't stand it so... that What's the matter, Wei Qing had no choice but to ask:

"Ok?"

Embarrassed, Qi Yibai hurriedly picked up his clothes to express his thanks, wrapped the grass in threes and twos, and arrived:

"Let's go, it's ready."

Along the way, an inexplicable embarrassment lingered around the two of them. As a result, they didn't say a word until they returned to the foot of the mountain.

At the final parting, Qi Yibai only said one sentence:

"I'll return the clothes to you tomorrow."

Just leave quickly.

Wei Qing looked at Qi Yibai's figure who couldn't wait to leave, and couldn't understand what Qi Yibai meant, should he ask someone to propose marriage?
