Seeing Lin Feng and the other two approaching, she turned and said:

"Just bringing two members? I've only left four people behind to provide protection, but the problem shouldn't be too big. Our people have already gone down in advance."

"After a few hours of light exposure, only the dark corners remain on the underground first level. Hundreds of Tier One mutants are hiding in the wasteland, and all of them need to be cleared out."

"To prevent them from attacking the transport team later."

"Your task is to cooperate with these four members to complete the cleanup of the underground first level. Currently, it's just some dark corners, and an area of two square kilometers needs special examination."

"Can it be completed in six hours?"

Two square kilometers, which translates to two million square meters, is quite a heavy task.

Lin Feng estimated that they needed to clean up 330,000 square meters of construction per hour, equivalent to 500 acres of land.

They needed to clear a large compartment every minute.

If they were quick, seven people should be able to complete it.

"No problem, but these four members don't need to stay by my side, just the two of them will suffice."

Lin Feng thought for a moment and replied.

Bai Ye nodded, asking four team members carrying flamethrowers to cooperate with Lin Feng and join the cleanup operation:

"Alright, this way the speed can be much faster, and the cleanup can be more thorough."

"Since everything's ready, let's start right away. Starting half an hour early will give us some extra free time."

After saying that, Bai Ye stepped onto the stairs and entered the ruins.

Lin Feng and his group followed, seeing the originally dim underground first level now as bright as early morning, bathed in sunlight.

And the beam of light above directly penetrated the darkness, shooting towards the entrance of the underground second level five kilometers away.

A second reflecting light-gathering mirror was being set up at the entrance to ensure sunlight could enter the underground second level.

Entering the dust-filled underground first level, Bai Ye soon bid farewell to the group.

She needed to command the battle on the underground second level.

The cleanup task was left to Lin Feng and his two companions, along with her four subordinates.

Apart from the captain, who had late Tier One strength, the other three were all around mid-Tier One, the same as Chen Shanshan and Shen Yue.

But this also showed the strength of the Salvation Army, at least comparable to any of the Five Major Villages of Oasis Town, and possibly even stronger than the strongest, the Nongzhuang Village's Li Family.

Being able to target the Li Family's Rock-Horned Horse breeding industry certainly required some expertise.

In the subsequent cleanup operation, Lin Feng only used a rapid fire cannon of ordinary power with 100 points of damage, which was more than enough to clean up Tier One mutants.

Mainly because they weren't wearing armor; even with polluted evolutionary cells augmenting their flesh and blood, they couldn't withstand the power of cannon fire.

During their escape, if they were injured and incapacitated, they'd be burned to death by the Salvation Army members wielding flamethrowers.

For the Salvation Army, using hydrogen and oxygen collected through ionization technology, as long as there was water, meant a continuous supply of cheap fuel.

Plus, with its own oxidizing agent, the energy value was astonishingly high, making it very suitable for use in the airtight underground ruins.

In this way, with Lin Feng's cooperation, a hundred shells were fired, successfully clearing out almost all the remaining mutants from the underground first level in four and a half hours.

At midnight, two hours earlier than the scheduled completion time, Lin Feng and his two companions returned to the surface cave.

The deputy leader of the Salvation Army, Ma Li, brought Lin Feng to a heavily guarded truck.

Taking a long test tube filled with a milky fluid from a cooler inside the truck.

Lin Feng accepted the evolution agent, feeling the abundant life source material inside flowing slowly, breathing heavily:

"Level 18 Rock-Horned Horse Life Source Material, Red Quality"

"Contains abundant life source material, double that of a Level 17 Evolution Agent. Consumption allows evolution to Level 18."

Ma Li was very satisfied with the completion of Lin Feng and his group's task, and then said:

"Take it and use it quickly. You're two hours ahead of the scheduled time, so you have three hours of rest because the second level hasn't been completely cleared yet."

"Captain Bai is leading people to clear it and encountered a Tier Three Distortion King on the underground second level. They injured it in a struggle in cooperation with sunlight, and it eventually escaped to the underground third level."

"This will help with the upcoming kill."

"Remember to return in three hours; maybe we can take care of it on the underground third level."

Lin Feng nodded, holding the Leader Level Rock-Horned Horse Essence Evolution Agent in his hand, returning to the camp.

Initiate self-evolution to Level 18!
