......

"Brother Xu Rui is back." Lin Xuechen said happily to everyone, and ran in front of Xu Rui at a trot all the way.

"Brother Xu Rui, you're back, how are you, are you hurt?" Lin Xuechen asked anxiously.

"Ah, I'm fine." Xu Rui scratched his head and continued: "They are so weak, how can they hurt me." ”

"No matter what, Xiao Rui is fine, Xiao Rui hasn't been back for a long time, everyone misses Xiao Rui." Hu Hongmei hugged Duoduo and said.

"Well, teacher, I'm fine, are you hungry, I have something to eat here."

Nalan Yi has been surrounding outside for several hours, Lin Xuechen and they have not eaten, and now they are indeed very hungry, Xu Rui took out the food, everyone has not seen each other for a long time, and this meal is extraordinarily fragrant.

"Brother Xu Rui, a few of us are soldiers." At this time, Liu Kaikang said: "Although this happened, but now that those people are dead, we have to go back." ”

"yes, I see." Xu Rui continued: "I am very grateful to you for being able to stand up when they are in danger, but I don't think it's a good time to go back, Nalan Yi's mount was not killed by me, but became smaller and hid, if I guessed correctly, he should be able to feel that I have gone far, so I am about to come out, I have some energy crystals here, since you have helped me, I naturally want to repay you, today I promise, all of you can complete an evolution!" ”

Xu Rui is very grateful to Liu Kaikang for being able to stand up and help Lin Xuechen when Lin Xuechen was in crisis, and now in this world, more strength is more hope for survival, so Xu Rui chose to repay in this way.

"Haha, with the words Brother Xu Rui, I will thank Brother Xu Rui first." Liu Kaikang continued: "I won't tell you, since this Nalan Yi came to the H City base, let alone my brothers, even me, I haven't taken all the energy crystals that are issued every month, he Nalan Yi was a fourth-level evolutionary when he came, and now we are still fourth-level evolutionaries." ”

After Xu Rui's energy crystals were promoted to the fifth level for Da Hei and Mi Yirou, a lot of fourth-level energy crystals were consumed, and even a dozen fifth-level energy crystals were consumed, and for Liu Kaikang, a dozen or so people, the fifth evolution was definitely not enough, and even the more than 300 fourth-level energy crystals in Xu Rui's hands were only enough for three or four people to complete the fifth evolution.

However, Xu Rui opened the space ring of the two Nalan brothers and sisters and Shan Qisheng only to find that these three people were poor and only had energy crystals left, and there were more than twenty fifth-level energy crystals alone, and as for the fourth-level energy crystals, there were as many as two thousand, and as for the lower-level Xu Rui, he didn't bother to count.

With so many energy crystals, Xu Rui can help Liu Kaikang complete the fifth evolution of more than a dozen people, so that Liu Kaikang and them will be safer after they go back, although Xu Rui is worried that Liu Kaikang will be treated unfairly after they go back, but Xu Rui respects the decisions they made, which can only help them enhance their strength and make them better protect themselves.

"That's without further ado." Xu Rui waved his hand and joked, "Start now, I'll protect you the Fa." ”

"Hahaha, then we're welcome." Liu Kaikang continued: "When the fifth evolution is completed, it is not too late for us to go back, then please Xu Rui brothers." ”

More than a dozen people have completed the fifth evolution one after another, and a dozen people have spent a total of more than a thousand fourth-level energy crystals, but the talent of these soldiers is also very good, and they have all completed the fifth evolution.

In the end, Xu Rui won Bai Mingyue's opinion, and Bai Mingyue finally said that he still wanted to follow Liu Kaikang back to the army.

Xu Rui felt very pity, after all, Bai Mingyue had a good relationship with Lin Xuechen, if Bai Mingyue didn't leave, Lin Xuechen would have a companion.

"Be careful on the road, this is not far from the base of H City, with your physical fitness, you can get there in half an hour."

"Okay, thank you Brother Xu Rui, then I'll go." Liu Kaikang completed the fifth evolution, and the whole person was a little more energetic.

"Well, let's go." Xu Rui said.

At this time, the sun was about to set, watching Liu Kaikang and Bai Mingyue and their party gradually walk away, Xu Rui had an inexplicable emotion in his heart, but Xu Rui knew that everyone had their own choice, and Xu Rui respected this choice.

"Wang Wei." Turning around, Xu Rui said to Wang Wei: "Hurry up, I have something to show you." ”

"Oh, something." Wang Wei looked at Xu Rui expectantly, because Wang Wei knew that most of the things that Xu Rui couldn't understand were good things.

Xu Rui hulahula, throwing out all the unknown items from foreigners and Kawaguchi Yuya.

"Huh!?" Wang Wei was very surprised and said, "What is this armor?" How can I rely on you to have so many evolutionary species!? Hey, hey, you're not going to loot that foreign research base, are you? ”

"How is that possible?" Xu Rui waved his hand and said: "I have inexplicably met a lot of foreigners who want to kill me, and I don't know why, although they are quite weak, but there are a lot of energy crystals on their bodies, which can make me make a windfall." ”

"Hey, hey, do you know how precious these evolutionary species are?" Wang Wei asked.

Xu Rui said casually: "How precious? ”

"The National Research Institute has recharacterized evolutionary biology, and you know that there are ten evolutions, and six levels, which are D-class, C-level, B-level, A-class, S-level and transcendental."

"Huh." Xu Rui interjected and said, "Isn't it double S level and triple S level." ”

"No, that's just a preliminary definition." Wang Wei continued: "Since the strength span of evolved creatures beyond the S-level is relatively large, and it is impossible to carry out precise classification with the current strength level of human beings, some time ago, the scientific research institute classified all the creatures beyond the S-level as transcendental. ”

"What does this thing have to do with this?" Xu Rui pointed to the evolutionary species and said without thinking.

"Don't worry, you listen to me." Wang Wei waved his hand and said, "And these creatures are divided into ordinary evolution beasts and spirit beasts. ”

"Spirit beasts? What kind of thing is this, it's so casual, how can it be like writing a novel? Xu Rui glanced at him and said.

"Spirit beasts, to put it bluntly, are evolutionary creatures with the ability to evolve without physical evolution." Wang Wei continued: "For example, Da Hei, Da Hei does not have a black flame, Da Hei belongs to the spirit beast. ”

"So, you still haven't said that this has anything to do with this evolutionary species." Xu Rui said frantically: "Say it quickly." ”

"This evolutionary species is only unique to S-class evolutionary creatures and transcendental-level evolutionary creatures." Wang Wei said solemnly: "S-level and transcendent-level spirit beasts don't have energy crystals, only this evolutionary species!" ”
