Lu Heng then lectured them on his understanding of zombies, giving a general overview of their late-stage development.
"High-level zombies will consciously raise a wave of lower-level ones to upgrade them. Once they reach the required level, they..."
Lu Heng suddenly stopped speaking. He realized that he was still struggling to find high-level zombies to obtain their crystals.
But he had completely forgotten that he had Lin Xue with him. A high-level zombie of over level ten could completely control the zombies below it, causing them to upgrade each other and provide him with the high-level crystals he desired.
"What's wrong, Brother Lu?" Li Qiang asked, seeing Lu Heng stop midway through his speech and stare blankly.
"Uh, nothing. Later, I'll take Qin Ye to Wuming City to have someone teach him how to fly a plane. Once he's roughly learned, he can fly it back.
During this time, I'll help you reinforce the outer walls here. They'll be enough to withstand high-level zombies. You still need to hurry and obtain more crystals."
"That's no problem. When are you leaving?" Li Qiang looked at Qin Ye, then turned to Lu Heng and asked.
"Tomorrow. Today, I'll help you upgrade the core personnel."
"Do you have high-level crystals? But it's not right for us to use your high-level crystals for free." Li Qiang mentally calculated his assets and felt that he had nothing to exchange for so many high-level crystals.
"No need. My trip out this time is to help establish strongholds everywhere, to enhance the defensive capabilities of nearby towns against zombies and reduce casualties among human survivors."
"This is truly great benevolence," Qin Ye couldn't help but exclaim.
"If I have the ability, I'll do more. I don't want to face these zombies every day either," Lu Heng chuckled.
"You guys count the numbers, find a private room, and I'll upgrade everyone. I'll go reinforce the outer walls for you now.
Qin Ye, you come with me to check the location of the city walls."
Reinforcing the city walls still required finding someone familiar with the area. If they accidentally enclosed a place with zombies and the people didn't know, it would be harmful.
"Okay, I'll accompany Brother Lu on this trip."
"Do we need to prepare anything?" Li Qiang also got up, ready to arrange for his trusted subordinates to gather.
"No, Qin Ye and I will go together."
There were many metal objects in the town. Lu Heng could control his metal ability to attract nearby metal materials and reinforce the earthen walls with a layer of metal plates.
Afterward, they began to split up.
Lu Heng asked Qin Ye to take him to the Roc. "You get on the Roc's back too."
"This strange bird is called a Roc? Is it also an animal from a fantasy world?"
It had to be said that Qin Ye read a lot of novels. He could associate the Roc, which he had never seen before, with being an animal from a fantasy world.
"Something like that. It's not exactly a fantasy world, just a world with more strange creatures and items than our ancient world."
"Do they have abilities like ours? Like, through cultivation, the ability to fly swords?"
"No, this Roc is their world's flying mount."
Lu Heng didn't want to hide anything from people with strong acceptance abilities, especially since Qin Ye's personality suited him quite well.
Climbing the ladder that hung down from the Roc's back, Qin Ye quickly scrambled onto it.
"Brother Qin, what does it feel like to ride that strange bird?" a young man watching from the side asked.
"The view is great, but it's a bit scary, hahaha." Qin Ye stood on the Roc's back, looking down.
"Brother Qin, are you going to fly later? Come back and tell us how it feels."
"Okay."
"Sit tight," Lu Heng, who had already jumped onto the Roc's back, said to Qin Ye, who was still standing and looking around.
Mimicking Lu Heng's actions, Qin Ye also sat in the rattan chair. He still didn't feel safe and used his ability to create many plants to tie himself and the chair together, preventing himself from falling off later.
Lu Heng glanced sideways at his actions, made no objection, and tapped the Roc's back. "Let's go, but don't be too fast."
For someone riding such an open-air flying vehicle for the first time, it was bound to be uncomfortable. Moreover, they weren't in a hurry, so there was no need to fly too fast.
"Wow! We're flying."
"Brother Qin, don't forget to tell us later..."
A group of young people below were cheering, shouting a few times.
"You guys keep it down, are you crazy? What if you attract zombies?"
A middle-aged man reprimanded the excited shouts of the young people. Although their levels were not low now, no one wanted to attract zombies from outside unprepared.
In mid-air, Qin Ye, who was instantly lifted into the sky, nervously gripped the vines of the rattan chair and looked down nervously.
Amidst the nervousness, there was a hint of excitement. After a while, he realized that the airflow around him was similar to that on the ground, with no excessive discomfort.
"Brother Lu, this Roc is almost like flying a plane."
"That's because I controlled the surrounding air and wind. I'll stop now, and you can feel it again."
As Lu Heng's words fell, the sensory experience around them instantly changed.
Wind like knives blew coldly past his face, and the air he breathed seemed to become thinner. Qin Ye couldn't help but shiver all over, and the plant leaves covering him enlarged, trying to preserve his body heat.
"Your plant control is quite good."
"Hiss, it's too cold. Can you restore it?"
Lu Heng smiled, and the surrounding air instantly became comfortable.
"Alright, keep an eye on the town's boundaries below. I'll help you modify them."
After a moment of recovery, Qin Ye looked at the town boundaries below and quickly pointed out their positions to Lu Heng.
Below, buildings stood in rows, and the town's layout was quite clear. Roads crisscrossed but were not chaotic.
Listening to the positions Qin Ye indicated, Lu Heng altered the layout of the boundaries in mid-air, then erected high city walls at the boundaries.
"Brother Lu, can I ask what level you are? And you know so many abilities."
Qin Ye could see clearly that at this moment, Lu Heng could not only control earth and stone but also metal.
The city walls below were built high and wide, with an additional layer of metal plates on the outside. The entire city wall looked high-end, grand, and indestructible.
"I know most of them. As long as it's an ability you've seen, I pretty much know it." Lu Heng once again flaunted his "wealth," though this "wealth" was the most useful ability after the apocalypse.
As for his level, he didn't say. With such diverse abilities, it was estimated that there wouldn't be another person like him on the entire planet.
