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

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

"Brother Tang, I went out this time and got an exoskeleton suit, it should be an alien civilization, you can ask someone to help you tomorrow to see if you can find a way to control it." Ye Yifan was no longer polite, and directly said what he said, and then said: "This is the main reason why I came to find Brother Tang, what about you, Brother Tang?

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

"Okay technician, I have a candidate, but he is my classmate, he has just been promoted to the middle class this year, and there must be a lack of time, and although he is a junior technician, he is very talented, the key is that he is very interested in machinery, and he will definitely be able to become a great tool after training!" Ye Yifan said with a smile, when Tang Boyuan mentioned this matter, the first figure that flashed in his mind was Zhao Hu's little guy, and then Frederick Alessandro, who had just been killed by himself, the latter's profession was a mechanic.

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

However, although the two are very optimistic about Zhao Hu's future, they don't think that he will be of any help to the current giant aircraft carrier of Huaguo Tianhang Group, including Ye Yifan.

As the chairman of Huaguo Tianhang Group, Tang Boyuan would not be so interested in a small junior technician, but the other party was personally introduced by Ye Yifan, it was completely different, even if it was not for the extremely talented junior technician, he would only do Ye Yifan a favor, he would not have the slightest opinion.

......

After returning to the school's quiet room, Ye Yifan quickly began to cultivate. To be honest, it is best to join a team when entering the wasteland, otherwise you will be like Ye Yifan, who has almost no time to rest and cultivate, and even if he has some understanding, he does not have any time to sit down and cultivate quietly, and he can only wait until he returns to the city to slowly digest the previous gains.

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

"Whew! it's so cool!" After breaking away from cultivation, Ye Yifan only felt refreshed, and he couldn't wait to yell a few times to vent the excitement in his heart.

But fortunately, at the critical moment, Ye Yifan resisted that impulse, he knew very well what the consequences of yelling in the ashram would be, and it would be light to be scolded by other students or teachers in the ashram at that time, and he might even be listed as an unnecessary student by the school ashram administrator, and he would not be able to apply to the ashram for a period of time in the future! This is not a joke, there have been precedents in the past.

"By the way, it's already a new week, the soldiers and heroes in the castle should be refreshed, hurry up and take a look, buy the peasants and talk about it. After recovering a little from the excitement, Ye Yifan immediately thought of this.

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

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

At present, Ye Yifan's crystal energy reserves in the castle have reached more than 10,000 units after recruiting the fourth hero yesterday, and recruiting all the new soldiers in the castle requires 20,765 units of crystal energy, and if the farmers, archers and infantry among them are upgraded by the way, a total of 23,010 units of crystal energy are needed, and the crystal energy reserves in the castle are naturally far from enough, at least it will take nearly three days to do it.

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

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

"The ratio of crystal energy to vitality required to buy a seventh-level soldier angel is the highest, reaching 15.6, which is too expensive, and then buy it last, the lowest ratio is the third-level soldier infantry, only 5.3, followed by the second-level soldier archer's 7.1, followed by the fourth-level soldier griffin's 8.3, well, the fifth-level soldier priest behind has reached 11.1, and the sixth-level soldier knight is 14.4, it seems that except for the third-level soldier infantry, the rest of the soldiers are basically the higher the level, the higher the ratio of crystal energy to life force required to buy. Ye Yifan quickly calculated this result.

"By the way, upgrading soldiers can also improve this 'surname-to-price ratio', upgrading first-level soldiers and peasants to militias is the most cost-effective, the ratio of crystal energy to vitality required for purchase is only 4.2, and at the same time, upgrading third-level soldier infantry to escort is also quite good, the ratio is only 5, and the farmer's surname price ratio is the same, which is not bad!"

"In this case, let's buy infantry first, as for upgrading infantry, let's wait until the time is needed, anyway, after upgrading, the vitality will be instantly replenished, which is equivalent to a lot of surplus vitality, and it may be able to save your life at a critical moment!" Ye Yifan felt that he had some signs of transformation into a "annihilation merchant" at this time, and he was calculating and calculating. However, he has no choice, he can only be fully prepared for a "loser" like Mr. Li, otherwise maybe Mr. Li will fall into a dangerous situation again at any time, so that the surplus vitality of the soldiers under his command is not enough!

"By the way, and the heroes, since the time in the castle is already a new week, it's time for the tavern to refresh. Suddenly, Ye Yifan thought of the hero in the tavern, and he immediately became excited, Ye Yifan had killed many dead soldiers of the Yamaguchi family in the wilderness, including Yamaguchi Jiyou, a strong man who was both an onmyoji and a Gu master, and the alien mechanic Frederick Alessandro, so Ye Yifan was very much looking forward to the heroes that were refreshed this time.
