After a meal, Ye Yifan felt that he benefited a lot.

After dinner, the two came to Tang Boyuan's study and continued to talk.

"Brother Tang, I got an exoskeleton suit when I went out this time. It should be from an alien civilization. I will ask someone to help me see if I can find a way to control it." Ye Yifan was no longer polite and said directly, and immediately said: "This is the main reason why I came to find Brother Tang, you. What about Brother Tang? If you have any worries, you might as well tell me. One person has a short plan and two are the best. Although I am not a professional, maybe the bystanders will be clear!"

"Of course there is no problem with this exoskeleton war suit. I will take it to the factory tomorrow for analysis. Maybe we can find some clues from the manufacturing process of that exoskeleton war suit!" Tang Boyuan agreed neatly: "As for my business, it is actually very simple, the company's competition is getting bigger and bigger, and good technicians are becoming more and more popular. I haven't recruited many good technicians this year. Isn't this worrying!"

"Good technician, I have a candidate, but he is my classmate. He has just been promoted to the first-level middle school class this year, so there must be some time shortage. Moreover, although he is a junior technician, he is very talented. The key is that he is very interested in machinery and will definitely become a great person after training!" Ye Yifan said with a smile. When Tang Boyuan mentioned this, the first figure flashed in his mind was that little guy Zhao Hu, followed by Frederick Alessandro, who had just been killed by himself. The latter's profession is a mechanic.

"Okay, tell him to come to my company to report when he is free, and I will arrange someone to guide him." Tang Boyuan said solemnly when he heard Ye Yifan's words.

However, although the two of them are very optimistic about Zhao Hu's future, they do not think that he will be of any help to the current giant aircraft carrier of China Sky Aviation Group, including Ye Yifan.

As the chairman of Huaguo Tianhang Group, Tang Boyuan would not be so interested in a small junior technician, but it would be completely different if the other party was introduced by Ye Yifan himself. Even if he didn't do that talented junior technician, he would just do Ye Yifan a favor and he would not have any opinions.

...

After returning to the quiet room of the school, Ye Yifan quickly began to practice. To be honest, it is best to join a team when entering the wasteland, otherwise he would have almost no time to rest and practice like Ye Yifan. Even if he had some insights, he would not have any time to sit down and practice quietly. He could only wait until he returned to the city to slowly digest the previous gains.

This time, the practice lasted nearly half of the night and was not over until the early morning of the next day.

"Huh! It's so good!" After releasing from the cultivation, Ye Yifan felt refreshed and wanted to roar a few times to vent his excitement.

Fortunately, at the critical moment, Ye Yifan resisted the impulse. He knew very well what consequences would be caused by yelling in the quiet room. It would be light to be scolded by students or teachers in other quiet rooms, and it might even be listed as an unpopular student by the school quiet room manager. He would not be able to apply for the quiet room again in the next period of time! This is not a joke, there have been precedents in the past.

"By the way, this is a new week. The soldiers and heroes in the castle should be refreshed. Hurry up and take a look and buy the farmers before talking about it." After recovering from the excitement, Ye Yifan immediately thought of this.

Immediately afterwards, Ye Yifan quickly made a purchase. He first bought all the newly emerging farmers in the castle and sent them to Tang Boyuan's command. With the support of the invincible ability of the benevolent, he worked hard to "pay taxes" for the castle, so that every farmer could serve as two, and he could provide the castle with 2 units of crystal energy income every day.

After doing all this, Ye Yifan began to consider which soldiers to buy.

At present, Ye Yifan's castle's crystal energy reserves have reached more than 10,000 units after recruiting the fourth hero yesterday. Recruiting all the newly emerging soldiers in the castle requires 20,765 units of crystal energy. If the farmers, archers and infantry are upgraded, a total of 23,010 units of crystal energy are required. The crystal energy reserves in the castle are naturally far from enough. At least it will take nearly three days to wait.

Therefore, when buying soldiers, you still need to plan and you cannot buy them all at once.

Of course, because farmers have the ability to pay taxes, Ye Yifan will take the lead in buying it every Monday, which is undoubtedly.

"The ratio of crystal energy to vitality required to purchase a level 7 soldier angel is the highest, reaching 15.6, which is too expensive. Finally, I bought it again. The lowest ratio is the third-level soldier infantry, only 5.3, followed by the second-level soldier archer, followed by the fourth-level soldier 8.3, Well, the fifth-level soldier priest behind the level 11.1, and the sixth-level soldier knight is 14.4. It seems that except for the third-level soldier infantry, the other soldiers basically have higher levels, the higher the ratio of crystal energy to vitality required to purchase." Ye Yifan quickly calculated this result.

"By the way, upgrading a soldier can also improve this 'cost-performance ratio'. It is the most cost-effective to upgrade a first-class soldier and peasant to a militia. The ratio of crystal energy required to purchase is only 4.2. At the same time, upgrading a third-class soldier and infantry to a guard is also quite good. The ratio is only 5. It is the same cost-performance ratio as the farmers, and it is quite good!"

"Since that's the case, then buy infantry first. As for upgrading infantry, we'll talk about it when needed. Anyway, after upgrading, the vitality will be instantly filled, which is equivalent to a lot of extra vitality. At critical moments, it may be able to save lives!" Ye Yifan felt that he had some signs of transforming into a "prodigal businessman" at this time, and was very careful in calculating. However, he had no choice but to have a "prodigal son" like Teacher Li, and he could only make complete preparations. Otherwise, Teacher Li would fall into a dangerous situation again, making the surplus vitality of the soldiers under his command not enough!
