Although they had doubts, no one dared to make a sound, all staring at Li Chenzhou, watching his next move.

Li Chenzhou held the two colorless and transparent ninth-level mutated crystal cores in his hand, as pure as crystal balls, and examined them closely.

He didn't expect that the legendary overlord-level crystal cores were actually colorless and transparent.

Almost all survivors knew about the color of crystal cores and often discussed it enthusiastically. However, in his previous life, there weren't such powerful ability users. Neither zombies, mutated beasts, nor humans had ever reached such a high level.

So, in his previous life, Li Chenzhou had been curious. Since that level of ability user hadn't been born yet, why had the colors of the crystal cores been rumored? He had completely dismissed those rumors as fabrications and never believed them.

According to the stories from his previous life, the lowest first-level crystal core was gray, followed by second-level green, third-level blue, fourth-level purple, fifth-level orange, sixth-level gold, seventh-level pink, and eighth-level red.

Finally, there were the two in his hand, the legendary colorless and transparent crystal cores that only overlord-level zombies or mutated beasts could produce.

Seeing that the color of the ninth-level crystal cores was indeed colorless and transparent, as rumored in his previous life, a wave of doubt washed over Li Chenzhou. At least, zombies or mutated beasts of levels seven, eight, and nine hadn't emerged in his previous life. So, where did these legends about the crystal cores, which turned out to be quite accurate, come from?

However, with so many eyes on him, Li Chenzhou couldn't afford to ponder these questions at this moment. Otherwise, those people might go crazy because time was running out.

Actually, the doomsday lightning ball in Li Chenzhou's hand was a fake. Although the store did have such high-powered lightning balls that relied on compressed energy and instantaneous release, ranging from small ones to doomsday-level ones, Li Chenzhou didn't want to exchange for one of those.

Because lightning balls were offensive weapons used on war fortresses. If he dropped one, especially a doomsday-level one, its power would indeed be as the voice had said, capable of wiping out an underground base comparable to a city.

But lightning balls were indiscriminate attacks. Even if he used one, Li Chenzhou himself would definitely be done for. Moreover, once activated, there was no way to reverse it.

Therefore, Li Chenzhou had exchanged for a simulated doomsday lightning ball. This thing not only looked exactly like a real lightning ball but could also simulate the energy levels of a lightning ball. At least in terms of feel, there was no difference between it and a real lightning ball.

However, a fake was a fake. The simulated lightning ball could only simulate. It was completely impossible to make it explode!

Originally, Li Chenzhou had seen in the description of the simulated lightning ball that it could perfectly simulate the energy fluctuations of a real lightning ball, so he thought of exchanging for one.

After all, there were high-level ability users here, and sensing energy fluctuations wouldn't be a problem for them. Then, he could use this to escape. And since it was just for bluffing, Li Chenzhou had simply prepared to get the most powerful doomsday-level one.

But when he wanted to exchange for it, he realized that the highest level that the simulated lightning ball could simulate was the destruction level. It couldn't simulate the power of the doomsday level, so he had to settle for a destruction-level one.

However, when saying the name of the lightning ball, Li Chenzhou borrowed the words "doomsday" because he felt that the name was quite cool.

At this time, after Li Chenzhou saw the ninth-level—that is, the overlord-level—crystal cores clearly, he pretended to confirm the energy within them and then put the two crystal cores back into the bag.

This action made everyone's hearts jump to their throats. There wasn't much time left, and he was still dawdling. Why take them out, look at them, and put them back? Were these crystal cores not up to par?

But then, everyone saw Li Chenzhou carefully placing the simulated lightning ball in his right hand gently into the bag. Then, he closed his eyes, circulated the energy in his body, deliberately acting like he was struggling, and slowly began to exchange the mutated crystal cores in the bag into the Mo Shi Sha Lu Zhe (Killing Shop).

In fact, the Killing Shop could instantly take away all the mutated crystal cores in the bag, but that would seem a bit fake. So, Li Chenzhou slowly controlled the speed, making the mutated crystal cores in the bag disappear little by little.

As the mutated crystal cores disappeared from the bag, Li Chenzhou deliberately controlled the energy fluctuations of the lightning ball to gradually decrease, which finally made the surrounding people breathe a sigh of relief.

Although the time had already passed the ten minutes that Li Chenzhou had mentioned, no one questioned it. They could even find the answer in their own hearts.

What he meant by ten minutes was that it had to start within ten minutes. As for the duration after that, because the energy was being suppressed all the time, the doomsday lightning ball would naturally no longer explode.

Among everyone, only Liu Xia Hui's heart was bleeding. He stared intently at the bag that was piling lower and lower.

After the crisis to his life was removed, Liu Xia Hui began to feel sorry for his property. These mutated crystal cores were all taken out in his name because the situation was urgent at the time, and it was impossible for him to go through any other procedures.

So, if there wasn't a good reason, he would have to repay all five hundred crystal cores.

Although he had been in the position of outer elder for so many years and had accumulated considerable wealth, taking out five hundred ninth-level mutated crystal cores at once was enough to make his heart ache.

If so many crystal cores were used to cultivate powerhouses, they could at least create six, seven, or even more ninth-level ability users.

Li Chenzhou didn't care about what others thought. He continued to exchange crystal cores at a constant rate. After about five minutes, he finally breathed a sigh of relief and took his hand out of the completely empty bag.

At this time, the energy fluctuations previously emitted by the lightning ball had long stopped. However, because the simulation was still ongoing, everyone around could still feel the terrifying energy contained within the ball.

Even though the lightning ball didn't have the extremely unstable energy fluctuations it had before, everyone felt that the energy contained in the ball seemed even more terrifying. No one knew what kind of power it took to suppress the energy to this extent.

"Okay, finally done!"

Li Chenzhou looked at Captain Jin and smiled:

"Although the energy of this doomsday lightning ball is even more terrifying, I guarantee that as long as I don't activate it, it will remain stable! There is no danger at all. Otherwise, would I be carrying such a thing around with me if I didn't want to live?"

Hearing Li Chenzhou's words, Captain Jin finally let out a long sigh of relief, then looked at Liu Xia Hui on the side, giving him a warning look.

Although Li Chenzhou seemed to be telling everyone that the lightning ball was not dangerous, the meaning in his words was actually very clear: it would be stable as long as "he didn't activate it." So...
