Relying on the crystal core to cultivate immortality, invincible in the world in the end times

At this time, Wang Li stood in front of a dozen people led by Lufa, and saw the advanced equipment that he had never seen in TV dramas, and his eyes were full of disbelief.

"Wang Li, everything here is confidential. If what you said was not too outrageous, I would never let you in."

"Why is it outrageous? Lufa, I am not lying. Our president really has the strength to fight against a level 7 superpower... Even he himself is level 6."

"Alas..." As if knowing that Wang Li would answer like this, Lufa couldn't help but sigh deeply.

He first glanced at the former, and then he directed everyone to take out the materials they were researching.

When stacks of heavy materials were placed in front of Wang Li, Wang Li's heart became more and more confused.

"What are these?"

"These are all the experiments we did after the monsters outside... That is, the alien species you mentioned came."

Lufa casually took out a copy from it, and on the side, Wei Zile took out bottles of special containers from a closed metal safe.

From Wang Li's perspective, various crystal-like substances of different sizes, colors, and shapes were placed intact in these transparent containers, like a sky full of stars.

"Heterogeneous nuclei?" A hint of surprise appeared in Wang Li's eyes. He had never thought that someone would choose to do experiments instead of absorbing the heterogeneous nuclei after getting them.

"Yes, these are heterogeneous nuclei, produced by different types of heterogeneous species, including levels one to five... As for level six and higher, we haven't seen them yet."

Lu Fa explained, and then changed the subject.

"I don't have higher-level heterogeneous nuclei here, not just because we haven't seen level six heterogeneous species, but more importantly, we won't be the opponent of such existence."

At this point, Lu Fa's face became obviously darker, as if he was disappointed with his incompetence.

"Then what does this have to do with what you said before, that no one can become a level six mutant at this time?"

Wang Li couldn't help asking. This matter made him full of doubts.

He was sure that Qi Lin's ability level must be at level six. The latter could even kill the War King who had raised his strength to the extreme with one blow, which further proved that Qi Lin's true combat power could be comparable to that of level seven.

"Well... Actually, after our research, we found an important problem."

Lu Fa's face was serious, and there was a certain complex meaning in his eyes.

"If a level five ability user wants to break through, he must use a level six alien core, otherwise... no matter how many level five alien cores there are, it is impossible to break through that layer of shackles."

"What?!!"

Wang Li's body froze, and his face showed an extremely surprised look, with a mouth so big that a pigeon egg could be stuffed in.

"Incredible, right?" Lu Fa spread his hands, his expression did not change much, as if he had guessed Wang Li's reaction.

"I didn't lie to you. This is the result of our experiment. I am now a level 5 peak mutant, and I am almost able to break through.

But I found that no matter how many level 5 mutant cores I took, the extra energy would dissipate in a strange way, and it was the invisible 'membrane' that shackled me that I couldn't break through."

Lufa's face was full of regret, and his fingers were clenched tightly, looking very unwilling.

After a long time, he finally recovered, and there was a hint of decadence in his eyes.

"Haha, Brother Wang Li, to be honest, according to my speculation, if a level 5 superpower wants to break through, it requires not only enough energy, but also a special thing.

That thing is not available in the level 5 superpower core... Not only that, even if a level 3 superpower wants to break through, it must take the level 4 superpower core.

Brother Wang Li, when you broke through the level 3, didn't you feel the 'membrane' that blocked you?"

"I..." Wang Li was dumbfounded. He really didn't pay much attention to this matter.

Thinking carefully, whether he or Li Zhuang and others, they did feel the bottleneck at that level.

But that was because they felt it when they were about to break through the foundation-building realm. Even the breakthrough in the superpower level happened naturally later.

"Uh..." Wang Li didn't know how to explain it, but now he had to admit that Lu Fa had some truth in what he said.

When he broke through, he relied more on the foundation-building pill provided by Qi Lin.

The energy contained in the elixir broke his own bottleneck, and when he broke through the fourth level, it seemed much easier than when he broke through the third level.

"It seems that you alsoI remember now. How about it? Does this matter break your cognition? "

Seeing Wang Li's expression, Lu Fa nodded slowly, assuming that the former had accepted his theory.

Otherwise, he should have started to refute it now.

But Lu Fa's words made Wang Li's expression suddenly become strange.

To be honest, he felt that Lu Fa's analysis should not have any big problems, because Qi Lin's breakthrough at the beginning was also based on the power of the elixir.

The elixir called Ju Ding Dan pushed the latter to the realm of Jin Dan, so the so-called sixth-level alien core was not used.

But this matter... he can't say it!

"Brother Wang Li, since you already know this, then I want to ask you, your president's breakthrough... is it not based on the sixth-level alien core, but simply on the energy accumulation of low-level alien cores? "

Lufa narrowed his eyes and looked straight at Wang Li, as if he wanted to see through him from the inside out.

"I..."

This was the third time Wang Li was speechless. Feeling Lufa's 'burning' gaze, Wang Li didn't know how to explain for a moment.

After a long time, Wang Li finally sighed deeply, and an extremely helpless expression appeared on his face.

"Let's do this, brother Lufa, I... uh..." Wang Li paused.

He also cast his eyes on Lufa... and the scientific researcher behind him who had put on a white coat at some point, holding a white paper in his hand, and seemed to be treating himself as an experimental subject. The corners of his mouth twitched slightly.

"Go down first, I'll talk to brother Wang Li alone. "Feeling Wang Li's gaze, Lu Fa spoke immediately.

Behind him, the researchers looked at each other, seemingly unwilling, but under the shock of Lu Fa's eyes, they slowly retreated.

After everyone left, Wang Li took a deep breath again, and his eyes became firm.

"Brother Lu Fa, there are some things... I don't know how to explain to you, otherwise, you leave with me, and I will take you to meet our president?"
