"At that time, I used the power of the 'source'." Xingyu said a little mysteriously.

"Source?" He Li asked, "What the hell is that?" ”

"Source......" Starrain paused, as if in deep thought, before saying, "It's a mysterious substance, something found in the ruins of Mount Olympus in Greece, and it seems to have been used as an ability at the time. ”

"At that time, it was found in the remains of an altar, and there were nine sources in total." Xingyu scratched his head, as if he was trying very hard to recall, and said, "Some of the people who found the source at that time were injured by the source to varying degrees, such as electric shocks, freezing, burns, and the like. ”

"After research, it was found that the nine sources contained nine different energies, namely wind, fire, ice, thunder, earth, wood, water, metal, and light." Xingyu continued, "And the energy in the source has been guided to have a high affinity for the human body, and it can be fused with the genome, so that the human has the ability to have the corresponding attributes. ”

"Then the source is applied to genetic research." Starshower continued, "Finally the Evolutionary Virus's anomalous sequence aspect has been studied. ”

"And you use the source?" He Li was a little puzzled, since there were only nine sources, it should also be a very precious thing, how could it be used by Xingyu?

"It was ......an accident," Starrain said, showing no fluctuations, "I got the ice ability from the Evolutionary Virus that I received very early on. And at one point, I followed my grandfather to the headquarters for a research conference, and on that occasion, I met the source at the headquarters and resonated with the source of the ice attribute. ”

"And then?" Seeing that Xingyu paused, He Li asked.

"I absorbed the source." Xingyu raised his head, as if recalling something, "At that time, the entire organization was shocked, and almost wanted to take me for research. ”

"Later?" He Li's eyes widened, she could imagine the situation of Xingyu at that time, it could be said that it was a piece of meat that fell in the wolf's den.

"Later." Xingyu just brought it casually, "For some reasons, I still wasn't used as a guinea pig to do the experiment, but I still had some conflicts with the 'gods', and then later, the experiment accidentally came to the end of the world." ”

He Li nodded slightly, she could also hear that Xingyu didn't want to talk about that matter, but she didn't ask again.

"Yuanma......" Xingyu said, "I will only know its magic until it is fused." ”

"The source contains a lot of power, and it is also driving my evolution very quickly, and it also gives me some other abilities." Xingyu said, "For example, it can stabilize my genetic mutation and prevent excessive disgusting mutations, and for example, I can sense the fluctuations of other people's abilities and understand the strength of others." There is also the same thing as when dealing with octopus zombies, channeling the energy of the source to instantly make yourself very powerful, but it is also more dangerous and has a great burden on the body. ”

"Not next time." He Li frowned and said, "If you can use the source for energy explosion, don't use it." ”

"Is my sister caring about me?" Xingyu suddenly showed a smile that was so bright that it was almost impossible to look at it directly.

"Count...... Sort of! He Li twisted his head to the side.

Suddenly there was a feeling of embarrassment, and there was no reason......

"Hehe, the source is still quite practical!" Xingyu said, and suddenly He Li seemed to feel that he couldn't keep up with his thinking again, "Sister, how about we find a chance to sneak over and steal that fire attribute source next time?" ”

"We'll talk about it then." He Li stuffed a piece of apple in his hand into Xingyu's mouth, "It's time to sleep, you can tidy up Xiaoyu here." ”

After speaking, He Li walked towards the bathroom.

"Hmm...... Not? Xingyu touched his head a little unknowingly, as if he hadn't done anything wrong, right? I don't know...... Forget it, let's get some rest first!

Xingyu also quickly tidied up and went to rest by himself.

……

The next few days were a rare few days of calm and tranquility, no one came to look for trouble, no tasks were issued in the base, and Su Ming did not come to ask for help or anything.

It's as if I've been idle all of a sudden.

He Li also likes this kind of leisurely and slow-paced life, looking around safely every day, walking the kitten with Xingyu, or having a friendly match with Beihuan Chen Mo Xingyu or something, anyway, it is quite relaxed and happy.

The tense apocalyptic atmosphere seemed to disappear all at once.

But this kind of good phenomenon is not likely to last long.

After a week of leisure, it ended.

The Survivor Base issued a notice about the official launch of an attack on the city.

The announcement said that according to the voting results, the survivor base decided to start the plan to seize the city, officially launched an attack on the city, the specific process is similar to the attack on the surrounding area, first rely on the elite squad composed of evolutionaries and elite sergeants to infiltrate the attack, after pulling out the mutant zombies that pose the greatest threat to the army, and then use the army carpet to infiltrate the city, clean up the ordinary zombies, and finally after all are completed, you can occupy the city.

It's a simple and effective approach.

"Are we still the ones who are unlucky for the time being?" After seeing the announcement, Xingyu was also smiling bitterly, "Who doesn't know that the biggest threat in the city is not the largest number of ordinary zombies, but those tricky mutant zombies!" We still have to lead the team to clean up these things. ”

"What's the solution, you can't let those armies deal with it, right? Without the heavy firepower in the base, those armies would probably have a hard time dealing with the fortified zombies. Bei Huan said on the side.

"That's right......" Xingyu pouted, "just complain!" ”

Immediately, Xingyu turned back to He Li and said, "Sister, you should be careful at that time, I don't know if there are more difficult things to deal with in the city, such as the giant mutant crocodile last time, I think it will be difficult for me to deal with even if I use the source, I don't know if it is still on Longxing's side now." ”

"Hmm." When it came to the giant mutant crocodile that was too powerful, He Li was also solemn.

Perhaps, the survivor base can be worn to death by relying on overwhelming firepower, but if you enter the city and rely on the evolutionary, I am afraid it will be difficult to deal with it.

……

That night, He Li and the others received four more invitations.

It was a gathering held by the commander-in-chief of the base, inviting all evolutionaries to participate, and it seemed to be very important.

All right...... I'm late again...... Procrastination is getting used to it...... Sorry sorry......
