Otherwise, it's estimated that it would take ten years to earn.

But without pressure, how can there be motivation?

Bai Ye quietly looked at the man in front of him, finding a hint of pleasure in controlling everything from his distracted expression.

Including Lin Feng in the plan, the success rate of the Salvation Army's raid this time would greatly increase.

After all, what they lack is the heavy firepower that the opponent's firearms superpower can provide.

Lin Feng, coming back to his senses, took a deep breath:

"Thank you, Leader Bai, for clarifying. If there's a future need for Pure Life Source Material, I'll definitely seek you out."

"Of course, if the Salvation Army under Leader Bai also needs firepower support, just come to me directly. As long as I'm available, I'll definitely lend a hand."

Lin Feng's response was very skillful, perfectly aligning with Bai Ye's intentions.

The silver-haired, fair-skinned beauty nodded in satisfaction, slipped the stainless steel thermos back into the gear belt at her waist, and continued:

"With Captain Lin ensuring safety in this relic mission, it's bound to go smoothly and be a resounding success."

"Please, Captain Lin, be ready to join the sweep task of the negative first floor in a few hours. After completion, I'll prepay with a piece of Life Source Material from a Level 18 Rock-Horned Horse."

"Once we clear the negative second floor, there will be a piece of Level 19 Source Material waiting for you to retrieve and absorb."

"Each upgrade in Evolution Level will directly restore the consumed state and internal superpower."

"This ensures the speed of the sweep task."

"The Scorching Sun Restricted Area behind us will reach the Taishan Ruins in less than eight days; we don't have much time. We must hurry, so please excuse us, Captain Lin."

Seeing how considerate the other party was, Lin Feng wouldn't mind these matters; after all, at most, upgrading Branded Equipment would cost him some Life Value, which could be recovered with half a piece of Evolutionary Meat.

As for the Mutants on the upper three floors of the sweep task, under the sunshine of Scorching Sun, Lin Feng barely needed to expend anything, just walking and finishing them off as he went.

From Bai Ye's perspective, doing so seemed a bit exploitative, because although continuous evolution could restore physical and superpower states, the fatigue of sustained combat could only be replenished through long-term sleep.

But there was no choice; time was indeed pressing.

The collection of machine tools from the military factory was just one part of the Salvation Army's entire operation, and the progress had already been significantly delayed by unexpected turmoil. Now they could only expedite the sweep task.

Fortunately, the man in front of him showed no sign of displeasure and gladly accepted his arrangements.

Bai Ye breathed a temporary sigh of relief internally and then arranged for Lisa to escort Lin Feng back to the camp for a good rest.

As he left, Lin Feng noticed some heavy equipment being removed by the Salvation Army members:

Many iron boxes and devices like flamethrowers.

And not just one set, but over a dozen sets.

He then recalled seeing Lisa and others gathered around a bonfire on the negative third floor earlier, leading Lin Feng to ask:

"Did the Salvation Army use flamethrowers to drive away those Mutants and enter the underground ruins?"

"Do you really have so much fuel? Is it gasoline?"

It's known that a regular flamethrower can sustain combat for at most an hour; sometimes, when the consumption is fast, the fuel reserve in the tank can be exhausted in less than half an hour.

As the most effective means for driving away and eliminating Mutants, Lin Feng had also considered using fire directly, but the cost of fuel deterred him.

Now, biofuel, including gasoline, diesel, and other common fuels produced from the once-industrial lifeblood oil of the Old Earth Era, has become very precious resources.

Only a few global migration routes pass through former oil-producing regions, extracting a small amount of oil in two to three years for reprocessing into fuel, barely enough to meet the consumption of the top elite of the apex elite of major forces.

Places like Oasis Town rarely see fuel,

How could the Wandering Force be so extravagant?!

Compared to traditional fuel engines, the 24-hour sun exposure in the wasteland makes solar-powered electric vehicles more suitable.

So, the vast majority of transportation means adopt electric drive modes, which although require many conditions and have many problems, they never lack an energy source.

Traditional fuels, compared to being used as fuel, are actually more suitable as weapons.

The power of a gasoline bomb is no less than that of ordinary explosives, and it performs exceptionally well for attacking settlements or Desert Beast Groups.

If the Salvation Army really had a large amount of fuel, why waste it inside the ruins?

After Lin Feng asked out of curiosity, Bai Ye's mouth slightly curved up, and he slowly began:

"If we found an oil well, why would we come to the Taishan Ruins? With oil, everything can be bought."

"It's not traditional fuel inside. The Salvation Army couldn't have so many resources; what's stored inside is actually hydrogen, to be precise, liquid hydrogen compressed by me."

"This stuff only requires the electrolysis of freshwater, but is only suitable for normal combustion, difficult to transport or use for other purposes."

After mentioning a few words, Bai Ye changed the topic:

"It's getting late; Captain Lin should go back and rest well, and be ready to participate at eight o'clock tonight."

Seeing that Bai Ye was reluctant to explain further, only mentioning this before giving a dismissal order, Lin Feng didn't insist.

With Lisa leading the way, they left the cave.

On the way back, Lin Feng asked about her experiences with the Salvation Army these past few days.

Previously, under the aura of the two big figures, Lisa had been too scared to speak, only burying her head in eating mastiff horse meat. Now, leaving the cave, she opened up and garrulously talked about her experiences from these days:
