"Is everyone okay?"

Grandpa Gu stepped forward and looked at them one by one before he felt relieved.

"Don't worry, we killed them all. We also met the Du family's caravan. My father still knows the head of his family, but this time it's his son who comes."

"Oh, it's the Du family who are extremely wealthy."

"Grandpa, you see we got a lot of things this time, and the food was given to nearby residents."

"Is there any leakage of whereabouts?"

"No, we all threw it into people's homes with our faces covered."

Li Yu proudly showed off to his grandfather.

Mr. Li nodded appreciatively, "Well done. In today's troubled times, if we can help, we can help. We are worthy of the support of the people."

"yes."

"Let's hit the road."

"Grandpa, we need to change our route to the largest town and get rid of these things as soon as possible."

Li Rui came to his grandfather to discuss.

"Then go to Shanhe City. Didn't you meet the Du family? Just give it to him."

"Would he notice that the Du boy is very shrewd and may have seen something."

Li Yu added.

"How can a businessman do business if he is not smart? Didn't you save him? Just let him return the favor. It will be convenient for you if he is relaxed."

"Okay, let's do some small business by the way."

Li Yu sat next to his grandfather and winked at him.

"You want to sell him the machine diagram?"

"Grandpa, this is what I think. The Du family is so rich that the country needs a backer. His father is dead, and the connections he had in the past may not be useful now. We need a lot of money to revive the family. Dad, grandfather, I think this is an opportunity."

"People may not need you, the Li family."

"Then add my Gu family, what Yu'er said makes sense. We need a lot of money to train soldiers and horses. Without soldiers and horses, how can we have power, and how can we negotiate terms with the clansmen."

Grandpa Gu is very supportive of Li Yu's idea, and he earned the opportunity by himself.

Mr. Li pondered for a moment, "In that case, you go ahead and do it. If it doesn't work, it doesn't matter. There are other ways. Don't give him important things."

"Don't worry, I know it. I'll sell him the machine diagram first, so I can make a friend and test my strength."

Li Yu showed a confident and flamboyant smile.

"Aren't you afraid that he will take the things away and do it himself, and dump you?"

Gu Lei deliberately tested her.

"Don't look down on people. He can make things with just a picture. I have learned all these years in vain. If he is really such a capable person, even if I fail, I have nothing to say."

"With such a capable person, he won't need you, let alone talk to you."

"The mechanism is not an ordinary thing. Because of her hobby, my father found her a direct descendant of the Mo family, and it took a lot of effort to let him teach a few children the skills of keeping secrets.

Only Yu'er has learned all the housekeeping skills."

Mr. Li just told the reason.

"I don't believe that the Du family can have such a talent. Then my father would need to rescue him. He almost got killed by gangsters."

Li Rui also shook his head.

It is difficult to learn the skills of the Mo family. They are looking for the last direct descendant of the Mo family. They saved his little grandson and they are willing to teach him the skills of being the best. His grandson doesn't know anything and they don't want his children to learn.

Save your life.

Li Yu had to study hard for several years in his past and present lives to achieve such a skill.

"So that's it. If we talk about it, what are you going to give?"

"How about a carriage and a crossbow?"

"Yes, the money for the drawings and the manufacturing should be separated. The drawings are the money for the drawings, and the work to build the car is a different price, it is not the same thing."

Gu Lei immediately added.

Li Yu's eyes lit up, she patted him on the shoulder and smiled like a flower, "Okay, your dog-headed military advisor must have thought carefully and share half of the money with you."

"You are my aunt, and you have such strong hands. You gave me the word "dog head", how unpleasant it sounds."

Gu Lei rubbed his shoulders with gritted teeth and glared at her.

"Then you two go and negotiate the price, and I'll just send you the drawings and do the work."

Li Yu raised her chin towards her brother, and acted as a hands-off shopkeeper as a matter of course.

"Okay, we listen to you, who makes you the eldest girl in our family."

Li Rui shook his head helplessly, his eyes full of doting, and he worked hard for his sister without any complaints.

"I'm looking for a treasure. Such a rich young master must be hung up."

Li Yu pulled out his box. There was no jewelry in it, but only folded drawings.

Gu Lei and others also stretched their heads to look curiously.

"This painting is quite detailed. Can't you really find someone to do it yourself?"

"It can't be done. Don't look at the dimensions, but in fact you can't find a carpenter to do it."

Grandpa Gu pointed to several parts of the mechanism and said, "The size of this place, the folding position of the mortise and tenon joints, do you know how to do it?"

"Oh, this is really fun for a layman to watch."

Gu Lei immediately understood that critical points require size and experience, which cannot be written down.

"What is this? It looks like a car to me."

"The crossbow is a large crossbow. It can hold a lot of arrows. It is made of fine iron and has a long range. It can penetrate shields."

Li Yu explained.

"That's awesome, have you made it?"

"Of course, I sent them away early. These are the blueprints that were successfully tested. They were all sent away in advance with the tribe."

Li Yu naturally had to make arrangements in advance when he came back from rebirth. Under the operation of his grandfather and father, he started building heavy weapons for the ballista a few years in advance. After the test was successful, it was directly transported and left the capital.

"The hills you bought near Wang's house earlier were probably just for these things."

"Yes, I have been doing experiments in Zhuangzi over in Tongzhou. After success, I sent them away directly. These can be dismantled."

Mr. Li said with a smile.

"It can also be disassembled."

Gu Lei was quite surprised.

"If you can assemble it, you can dismantle it. Otherwise, how would you transport it if it is so big? It would be troublesome for people to find it."

Ever since the late emperor took back the military power of the Gu and Li families in his later years, the Li family began to make various preparations, including the manufacture of these heavy weapons.

It was Mr. Li's surprise that Li Yu could become so proficient in mechanism manufacturing. It gave him a little more confidence to preserve the clan. Having an expert in mechanism manufacturing would give him even more wings and he would be sure of a comeback.

With Li Yu's rebirth and advance arrangements, the Li family's losses were relatively small.

"Yu'er, you can't give the ballista to the Du family."

"How can I give him this? Just give him a small toy and let him protect himself. In addition to the ballista, I have other things, but the mechanism costs money."

Li Yu smashed his mouth.

"It doesn't matter, just go ahead and fix it, I'll take care of the money."

When Gu Lei saw these drawings, hope ignited in his heart. He might really have a chance to return to the capital and avenge his father and relatives.

Grandpa Gu saw the fighting spirit rekindled in his grandson's eyes, and was very pleased. He didn't want his grandson to fall into pain and be unable to extricate himself because of the deaths of his sons.

"Lei'er, Brother Rui, you two are responsible for holding the Du family in check. The Du family has money, but lacks the protection of connections. Du Tianlin is dead, and the Du family may not be stable now, otherwise he would not come to escort the goods in person."

"General family heads would not do such dangerous things. If the head of the family dies and there is no leader, the whole family will be in crisis. It is not a wise choice."

Grandpa Gu held the teacup and analyzed it.

"We've gone to Shanhe City and let's take a closer look at the situation."

"Give him this arm crossbow as a gift, as a bonus."

Li Yu took off his arm crossbow.

"How can you give your things to other stinky men? Use mine."

Gu Lei refused without hesitation. How could Yu'er's things be used by other men.
