The elevator descended for a full three or four minutes before finally stopping. Li Chenzhou knew he was right; this underground base was definitely very deep underground!

As the doors opened, Qing Cang pulled Li Chenzhou out of the elevator. They walked for another two minutes or so, turning several corners before entering a room. Only then did Qing Cang remove his blindfold.

"I'm sorry, Brother Li, but the location of the base is crucial. It's a matter of life and death for over a hundred thousand people, so we have to be careful. Please forgive us!"

As soon as he removed the blindfold, Qing Cang quickly apologized.

"It's okay! I understand! After all, there are Devourers outside. It's always best to be cautious!"

Li Chenzhou said with a smile, "Besides, from the perspective of a potential ally, the more careful you are, the more trustworthy you are!"

"Thank you!"

Qing Cang nodded to Li Chenzhou and then said, "We've already reported to the higher-ups. After they've studied the situation, they'll come to meet you. In the meantime, you can rest here. Food and water will be sent over soon! Goodbye!"

With that, Qing Cang smiled and nodded at Li Chenzhou before turning to leave.

"Wait!"

Li Chenzhou immediately stopped him. Qing Cang turned back, looking at him with a calm expression.

"You... you're going out, right?"

Li Chenzhou asked, looking at Qing Cang.

"Yes! My sister was captured by the cage fighters! I can't let her be captured alone!"

Qing Cang nodded.

"If your sister is captured, will she be devoured immediately?"

Li Chenzhou asked.

"It's uncertain. The Devourers take the people they capture back to their lairs, because they're all waiting there. But they also devour people on the spot sometimes, so no one knows which they'll choose!"

Qing Cang shook his head.

"So, the only way you can see your sister right now is to get captured by the Devourers' cage fighters, right?"

Li Chenzhou asked again.

"Yes! Although we know the location of the Devourers' outpost here, being captured is the fastest way. And right now, we can't let the Devourers know that we've already located their outpost!"

Qing Cang replied.

"The Devourers have an outpost here?"

Li Chenzhou was overjoyed to hear this!

"Yes!"

Qing Cang replied.

"Then I suggest you wait a bit. Maybe... if we cooperate, we can give the Devourers a surprise!"

Li Chenzhou thought for a moment and said, "But I need to understand your situation first, including your strength and the Devourers' strength. Only then can I make a decision!"

"You?"

Qing Cang was taken aback. In fact, he didn't think Li Chenzhou's arrival was particularly good news. After all, Li Chenzhou's planet hadn't been invaded by the Devourers yet, which meant that the highest-level ability users there were only at level five, definitely no higher.

What help could a world where a level five ability user was considered a top fighter possibly provide them? Even Qing Cang himself was already a level seven ability user!

Before, when he decided to bring Li Chenzhou back, Qing Cang was thinking about whether to transfer some of their children to Li Chenzhou's world to hide temporarily.

But then, Li Chenzhou's words had shocked them, so Qing Cang chose to report the matter and let the higher-ups deal with Li Chenzhou!

But now, Li Chenzhou was actually saying that his cooperation with them could give the Devourers a surprise. What surprise could a mere level three kid bring?

Seeing Qing Cang's expression, Li Chenzhou smiled and reached into his backpack, taking out a bottle of evolution serum!

This action was naturally a cover. Before, in his own world, Li Chenzhou was sure that there was no one stronger than him, and he also had Gray Bear and the others, so he wasn't very careful about hiding his secrets.

But here, he had to be more careful. So, he pretended to take out the evolution serum from his backpack so that even if Qing Cang and the others wanted to steal it out of greed, they would only find some food and water in his backpack.

"This is called evolution serum. It was developed on our side!"

Li Chenzhou handed the evolution serum to Qing Cang and said, "Its function is similar to that of mutated crystal cores, but it has no level restrictions. Unlike crystal cores, it doesn't require a corresponding level. Moreover, using it to increase your level gives you a higher chance of acquiring skills and talents!"

"Evolution serum?"

Qing Cang took the evolution serum and examined it carefully, even sniffing it. Unfortunately, the evolution serum was sealed very well, and he couldn't smell anything.

While Qing Cang was holding the evolution serum, Li Chenzhou was carefully observing him. In fact, taking out this serum could be said to be a very risky move.

After all, this kind of serum that didn't restrict levels and could be used to continuously improve oneself was too heaven-defying, and it was bound to arouse greed!

However, because the Devourers were in this world and even had an outpost, Li Chenzhou had to rely on the power of this world if he wanted to strike at the Devourers!

Because he was currently limited by the level suppression of his own world and didn't want to raise his own level, Qing Cang and the others were a good choice.

Moreover, although he hadn't yet gained a deep understanding of the people in this world, Li Chenzhou felt that these guys who were willing to let the Devourers capture wave after wave of strong people in order to avenge themselves, and even didn't suppress their own levels to avoid the Devourers' attacks, shouldn't be so short-sighted!

In any case, he would only take out one bottle of evolution serum. Qing Cang and the others wouldn't fall out with him over this one bottle. In order to get more evolution serum, they had to cooperate with him.

That way, Li Chenzhou could first use this world to strike at the Devourers. Regardless of whether he won or lost, at least he could obtain more information about the Devourers and prepare for the future war!

"How do you use this thing? Just inject it into your body?"

After looking at it for a while and not seeing anything, Qing Cang raised the evolution serum and asked Li Chenzhou.

"Yes! Just inject it into your body!"

Li Chenzhou nodded. "However, although it has no level restrictions, the success rate is inversely proportional to your level. What level ability user are you now?"

"Level seven!"

Qing Cang didn't hide his level.

"Okay! Then your failure rate for using the evolution serum will be seventy percent!"

Li Chenzhou said, "In other words, if you use the evolution serum, you have about a one-third chance of entering the level eight ability user realm, and if you succeed, you'll definitely gain a skill, and there's a good chance you'll gain a talent as well!"

"One-third? That's crazy enough!"

Looking at the serum in his hand, Qing Cang murmured. Then, he looked at Li Chenzhou and directly removed the syringe's protective cover, stuck the needle into his arm, and injected the serum into his body...
