After resting at the base for one night, Hou Yong came to pick up Yang Heng the next day.

Yang Heng didn't rush to give Qian Xiaoyi to use the evolution crystal, since the self-awakened can be quickly upgraded, there is no need to use these things for him.

It's better to wait until you figure it out, otherwise Yang Heng is afraid of any accidents.

……

Along the way, Yang Heng saw that many construction sites were under construction, and a large number of materials were sent everywhere.

"What's being built over there?" Yang Heng asked curiously.

"Exchanges." Hou Yong opened his mouth and said, "In the future, it will be used to trade crystal nuclei."

"Is that it?" Yang Heng took out an evolution crystal.

"Yes, the base needs to cultivate a large number of evolutionaries, and the crystal nucleus in the head of this zombie can be strengthened by ordinary people, but it is difficult for ordinary people to hunt evolved zombies.

And the evolutionary has a little crystal nucleus and directly strengthens himself, how can there be any left,

So the number of crystal nuclei in the base is very small.

If this continues, it will fall into a vicious circle, so the commander hopes that high-level awakened and evolved people can hunt zombies in large numbers, and the low-level crystal nuclei obtained can be used for trading, in exchange for weapons, or the help of the base.

In this way, on the one hand, it can replenish the low-level crystal nuclei of the base, and on the other hand, the evolutionary can get better weapons and hunt more powerful zombies to evolve, killing two birds with one stone. Hou Yong explained excitedly.

Yang Heng thought for a moment and asked, "How do you all use crystal nuclei to strengthen?"

"Eat it directly, although it is a little painful, but there is no way." Hou Yong smiled bitterly: "Those researchers have a way to extract the energy inside, so that people can evolve without pain, but the speed is too slow, and it will take a few days."

"They are also researching now, and if they want to break through the current technological shackles, they just don't know when they have to wait, and now, everyone still has to endure this pain."

"Is it painful to be strengthened every time?" Yang Heng pretended to ask casually.

"Yes, although it doesn't hurt as much as the first time, it's better to live than to die."

Yang Heng was silent after hearing this, he seemed to be so painful only the first time, and he was already much better the second time, but as for the back, he basically didn't feel it anymore.

Is it because of your own constitution?

Or is there a problem with the first evolution crystal you used?

Oh, it should be called a crystal nucleus now.

Hou Yong is still E-level, why did he break through so quickly?

Yang Heng didn't believe that the resources of the base would be so small that he wouldn't even give him an E-grade crystal nucleus.

Could it be that he is really an Awakened One?

And then the reason why I took the crystal nucleus again?

Looking at the crystal nucleus in his hand, Yang Heng fell into deep thought.

"What do you think?" Hou Yong spoke up.

"It's nothing," Yang Heng said, and by the way, he took out some crystal nuclei from his pocket and handed them to Hou Yong: "Give these to you, I don't need them either."

These crystal nuclei were all taken out by Yang Heng last night, and they are all E-level, which should help Hou Yong break through to D-level.

Just take a look at how many of them he can break through, so that he can confirm whether the number of crystal nuclei used by everyone to break through is the same, so that he can confirm whether he is because of good qualifications or other reasons.

"Where did you get so many crystal nuclei?" Hou Yong was surprised, Yang Heng had to have ten in his hand.

That's more? I don't want to scare you to death if I take it out of my pocket.

"Is it much?" Yang Heng didn't think so.

"That's not much?" Hou Yong took the crystal nucleus,

"I told you just now that there are very few crystal nuclei in the base, and everyone needs to evolve, and the supply exceeds demand."

"I just need this, so I won't shirk it, and I won't say much about thank you, if you need anything in the future, just ask."

"As long as you don't violate the rules of the base, I will definitely help if I can!"

"Okay." Yang Heng should arrive.

"By the way, there will be not only exchanges in the base in the future, I heard that there will also be a leaderboard." Hou Yong said after carefully putting away the crystal nucleus.

"Leaderboard?"

"Well, the strength ranking of the Awakened and Evolvers is jointly made by various countries, and it is comprehensively evaluated through personal merits, achievements, ranks, etc."

"Is it any use?" Yang Heng asked.

"It's said that it's for everyone to compete healthily, and it can also be exchanged for resources."

Yang Heng felt that this was not bad, if he wanted to explore other planes in the future, he would definitely need a lot of helpers, and this ranking could at least help him contact the people he needed.

Otherwise, it would be difficult to explore so many planes or ruins on your own.

……

Hou Yong took Yang Heng to the front of a building, and entered the elevator after passing the security check.

Hou Yong pressed the elevator and explained: "This is an underground base, and the headquarters, the scientific research department and some important resources are below, in order to prevent attacks, it is safer."

Yang Heng nodded, followed behind Hou Yong, and walked out of the elevator.

"You go in, the commander is waiting for you inside." Bring Yang Heng to Hou Hou Yong and guard outside the door.

Yang Heng went in alone.

The office is not big, only a sofa, a desk, and behind it is a middle-aged man sitting on a chair and bowing his head to write, and behind him is a whole row of bookcases.

"You sit down for a while, and wait until I'm done with this thing" The middle-aged man didn't raise his head too much, and said, "There is tea on the table, pour it yourself."

The biggest official Yang Heng has ever seen in his life is the city leader who used to inspect the orphanage, and he is nothing compared to the power of this person.

Yi Yang Heng's current level at the peak of the D-rank actually felt some pressure.

Worthy of the person in charge of a base.

Yang Heng could clearly feel that the commander himself was just an ordinary person.

There is no one among ordinary people who can stress themselves.

Sitting on the sofa, Yang Heng poured a cup of tea and drank it to himself.

……

"You are Yang Heng, I often hear Fang Ling mention you, and I have long wanted to meet you." The middle-aged man finished his work, got up and said.

"Hello Commander Fang, I'm Yang Heng." Yang Heng got up and returned.

"Sit down, see you this time, nothing else, on the one hand, I'm more curious, you're the first person to break through to the D-level without relying on any base resources, I'd love to meet,"

"In addition, I want to invite you to officially join our Base Seven."

"The bases of various countries are preparing to update the rankings online, Xiaohou should have told you, right?"

Yang Heng nodded.

Seeing this, Commander Fang continued: "I hope that you and the other D-level can strive to occupy a better ranking, which will be beneficial to our country in the future."

"As for the reason, there are some things you want to know, which are secrets of various countries,"

"When you get the ranking and get the resources for the country, I'll tell you, it's a reward for you, how about it?"

"Okay, do I need to go through any formalities?" Yang Heng felt that this was very fair.

"No, the formalities have been completed, just let Xiaohou take you to sign it in a while." Commander Fang said.

"Okay, then I'll go first."

"Go ahead, if there is anything unclear, just ask Xiaohou, and he will tell you."

"Thank you."

Yang Heng closed the door, and the commander inside the door returned to his desk to continue working......
