The so-called Yin Evil Steel is merely a hundred-refined steel that has absorbed a great deal of Yin Qi and Evil Qi. As for the hundred-refined steel, it can be made from fine iron.

Chu Xuan's storage bag had long been prepared with plenty of fine iron for the routine maintenance of magic tools. He only needed to find a place rich in Yin Evil, bury the hundred-refined steel there, and let it absorb the Yin Evil Qi. If he set up an array to gather Yin Evil Qi, the formation of Yin Evil Steel would be even faster.

Yu country had long been controlled by the righteous five sects, and these places rich in Yin Evil Qi were likely under the watchful eyes of the righteous cultivators. Should he dare to approach, he would certainly be subject to repeated questioning by them, and possibly even face life-threatening risks. But on this planet, Chu Xuan only needed to find a place with many zombies, kill them in batches, and let the Yin Evil Qi condense.

"To gather Yin Evil Qi, without tens of thousands of zombies, it would hardly be possible. I need to look around nearby," Chu Xuan nodded slightly.

He released Long, Hu, and Bao to search the southern part of East Lake City, while he himself rode the Heavenly Star Flying Sword northward. However, although there were many zombies in East Lake City, they rarely gathered together, wandering aimlessly instead. Gathering these creatures would certainly be a great effort. After searching for several days without discovering a large gathering of zombies, Chu Xuan furrowed his brows.

That day, Chu Xuan prepared a lavish lunch for himself. Just as he was about to start eating, Bao suddenly returned, barking several times in succession.

"Hmm?" Chu Xuan listened carefully and quickly understood what Bao was saying. "There are quite a few tough-to-chew zombies appearing in the south of East Lake City?"

"And there's a human squad fighting them? Interesting." Chu Xuan raised an eyebrow.

Tough-to-chew zombies likely referred to higher-level zombies. After all, for Long, Hu, Bao, and the others, the zombies here were just food. The higher the level of the zombie, the tastier they found them. A large appearance of high-level zombies could be a sign of something. A lightbulb went off in Chu Xuan's mind.

In various zombie-themed works he had seen before, they often mentioned something called a zombie tide. The causes of zombie tides were bizarre and varied. It might be due to a single zombie hearing something, or chasing a living person, thereby leading a group of zombies to move together.

Zombies along the way, hearing the noise, would also join the group. Thus, like a rolling snowball, this would lead to the group growing larger and larger, eventually forming a terrifying zombie tide. Everywhere it passed, all living things would be obliterated.

This wave-like swarm of zombies was particularly terrifying for human survivors. It was almost no different from a natural disaster. Of course, a zombie tide might also be led by high-level zombies. Some unique high-level zombies naturally had the ability to command lower-level zombies. This could also cause the snowball effect, expanding the number of zombies in the group to an incredibly terrifying degree.

A large appearance of high-level zombies was likely the precursor to a zombie tide. With this thought, Chu Xuan immediately became excited.

Stolen from its rightful place, this narrative is not meant to be on Amazon; report any sightings.

Zombie Tide! What does this mean? Tens of thousands of zombies! No, perhaps even more! Isn't this the perfect opportunity to create a land rich in Yin Evil Qi?

Chu Xuan quickly finished his lunch like a whirlwind and immediately rode the Heavenly Star Flying Sword towards the south of East Lake City.

After flying out of East Lake City's territory, he indeed saw a vast horde of zombies heading toward the City on the ground. Even a cursory scan showed that the number of zombies exceeded fifty thousand!

"Good!"

Chu Xuan was invigorated. He didn't pause; he immediately returned to the Haotai Hotel to start preparing the formation. He needed to have the formation ready before the horde arrived. He couldn't miss this great opportunity!

...

Black Blade Security Company.

A van carrying several exhausted individuals returned to their base.

Wang Gangjian, Wang Yong, and Tang Jinchuan jumped down.

Song Dayi came quickly and asked in a low voice, "How did it go?"

Wang Yong held up a hand, lowering his voice, "Five, exactly five first-level zombies."

Song Dayi gasped.

"Brother, we should retreat. The appearance of five first-level zombies at once is definitely a sign of a zombie tide!" Wang Yong looked at Wang Gangjian, unable to resist saying.

Tang Jinchuan nodded repeatedly, "I agree."

Wang Gangjian sighed deeply, "What use is my being a second-level Superhuman, if in the end, I still have to abandon the place where I grew up and leave my hometown?"

Wang Yong sighed, "Brother, your promotion to second-level Superhuman is great, but there's nothing we can do about a zombie tide. Under a zombie tide, how can there be any survivors? Even if you were a third-level Superhuman, you wouldn't survive."

Tang Jinchuan nodded, "I agree."

Wang Gangjian waved his hand, "Give the orders, let everyone pack up and prepare to evacuate East Lake City. Tang and I will carve out a route, Xiao Yong, you go south to scout and see if there really is a zombie tide. Dayi, pick a few brothers who can fix cars, look around nearby, and see if there are any more vehicles that can carry people. Our vehicles definitely won't be enough to take everyone."

Wang Yong, Tang Jinchuan, and Song Dayi all nodded seriously and immediately got to work.

Under the management of Wang Gangjian and his team, the several hundred people of Black Blade Security Company were well-disciplined.

In two days, personnel and supplies were ready.

However, the vehicles they found capable of running were still very limited.

Even if each vehicle was packed to the brim, they could only fit about a hundred people.

At this moment, Wang Gangjian and his three companions gathered in the hall, with a map of East Lake City spread out in front of them.

Wang Gangjian spoke solemnly, "Everyone, the zombie tide is indeed coming, and we probably have about four days. But we still lack vehicles, not enough to take everyone away. The only solution now is to look for trucks, buses, and other large vehicles."

Wang Gangjian stretched out his finger and circled several spots on the map.

"These places, which include the bus company and large factories, may have undamaged trucks and vans. Our top priority is to secure these vehicles!"

He looked at the three men, "Pick a location each."

None of the three complained and each went to a different site. They did not, because they were Superhumans, hold themselves above others or regard the lives of ordinary people as mere dust.

There was a time when they too were at the bottom of society. Having been rained on themselves, they now sought to provide shelter for others.

East Lake City Bus Company.

Tang Jinchuan, along with three strong men, drove to this location.

The van stopped.

Tang Jinchuan squeezed out of the van door with some difficulty before getting down.

One of the men behind him chuckled, "Bro Tang, you're so fat, it might affect our escape. If there are high-level zombies here, you definitely won't run as fast as us."

The other two men joined in the teasing.

Tang Jinchuan scoffed, patted his belly, and immediately a wave rippled through.

"What do you know, this fat on my body is what's going to save my life! You'll see when we really face danger!"
