Lu Yuan's words enraged everyone.

"What the hell are you talking about? Maybe it's our problem? I've seen shameless people, but I've never seen anyone as shameless as you."

"Hmph, if you can't figure it out, just say so. Why do you have to pretend? You can't fix it and you blame us? Do we owe you something?"

"Exactly, exactly. All talk and no action, no real skills whatsoever, yet they dare to pretend to be experts here. They should just be dragged out and shot."

"Sigh, we shouldn't have helped this guy get all this stuff out in the first place. The captain was so naive."

The group chattered amongst themselves, and the captain's face flushed red and then turned pale.

Finally, he clapped his hands and said, "Alright, stop talking. I vouch for him. You all do these things the way he says. If he really can't do it, I'll deal with him myself. Go and get ready."

He also knew that these things were very expensive and required very careful handling.

Therefore, he did not intend to let Lu Yuan handle it alone, but instead entrusted it to these people.

That way, he can reduce his responsibility a little bit, while the group of lab technicians in white coats below all looked bitter.

"What? They're really making us scapegoats. We're not taking the blame for this."

"So, if we break it, it's our fault; if we fix it, it's his fault. What does that mean?"

"Alright, shut up. The military is the boss of the region now. If you don't listen to them, none of you will get away with it."

"Sigh, let's get ready to go. I want to see what kind of tricks this little guy can pull."

Following Lu Yuan's instructions, the group of lab technicians began to combine these items one by one.

Finally, after several hours of hard work, the group managed to gather the things that Lu Yuan needed.

After Lu Yuan had them do one more thing, they extracted less than five milliliters of black liquid.

After seeing the black liquid, everyone felt a pang of heartache.

Such a large pile of materials, totaling nearly one hundred kilograms, was refined into nearly five milliliters of black liquid.

What if this doesn't work?

The captain's face twitched; these things were a complete waste to him.

This cost so much money; if I can't fix it, I might get fired.

He's now in the same boat as Lu Yuan, and he truly regrets believing the other's lies.

"If this stuff doesn't work, I'll just drink it myself, okay? Don't worry, I guarantee there will be a reaction after it's dripped in!"

So, Lu Yuan took the bottle that looked like eye drops and went to the big tree.

He instructed everyone to cut a slit in the tree trunk.

Then Lu Yuan dripped the black liquid onto it.

Moments later, the giant tree began to turn black at a speed visible to the naked eye.

The rate at which it turned black even exceeded the rate at which the human eye could perceive it.

The speed was like lightning; the entire root, which was over a hundred meters long, turned into a black, withered branch in an instant, and then the whole root seemed to be carbonized.

Everyone was stunned.

They never expected that such a huge tree would be destroyed by Lu Yuan so easily.

Everyone was speechless for a moment, and the experimenter below, after using all his strength to cut off a piece of root from above, discovered that it was actually a piece of charcoal.

They were shocked, everyone was shocked.

When the lab technicians placed the charcoal on the table, everyone immediately began to examine it.

After a series of tests, the results finally came out.

"That's right, it's charcoal. I didn't expect that just a few drops of liquid could destroy this thing. Should we start mass production in the future?"

"Are you kidding me? This is all we have in our warehouse. Don't even think about mass production!"

"Wow, even though we've used up the only one we had, at least it's useful now. We can produce these things using his method from now on!"

"Great! We've finally found a way to destroy those giant trees!"

The crowd cheered.

Lu Yuan breathed a sigh of relief.

He is now the center of attention, and no one questions his ideas anymore.

Captain Liu's face was flushed with excitement, like a child's. He hugged the people next to him, then came to Lu Yuan, unsure how to express his excitement.

He looked at Lu Yuan's quiet demeanor and extended his hand.

"Thank you, thank you for saving my position!"

Lu Yuan shrugged and gently shook hands with the other person: "Then can I go home now?"

"Of course, heroes should go home. Don't worry, we won't interfere in your affairs anymore!"

"Alright, you guys should get those things out of there as soon as possible to prevent the water source from being polluted. The water source is very important to us!"

Lieutenant Liu nodded emphatically: "I will definitely take care of this. Don't worry, I'll arrange for someone to get these things out right now!"

So, Lu Yuan exchanged pleasantries with the other party for a while. As he watched the people from the First Division pull out pieces of black charcoal from below, he felt as if he wanted to take one back to study.

So he made his demands, and Captain Liu agreed to Lu Yuan's conditions without hesitation.

Lu Yuan stood there, looking back and forth at the piece he wanted to take, when suddenly he noticed something amiss on a tree trunk.

Lu Yuan pointed to a grayish-white substance on the ground that looked like dried plastic sheeting and asked, "Where did you find this?"

The soldiers who had just dived down to retrieve the charcoal heard Lu Yuan's question, put down the charcoal, and replied, "It's underwater! There's a lot of tree bark in that area! Isn't this just tree bark?"

Lu Yuan frowned slightly.

He rubbed the thing with his hand, and at that moment it didn't feel like tree bark, but rather like a layer of keratin that had shed from the human body, just like animal keratin.

So he found many more of these things nearby, and then he held them up to the other person and said, "Take more of those things up from below as soon as possible, I want to see them!"

The other party was slightly taken aback, but still agreed.

When they brought their things up, Lu Yuan found the softest piece.

He examined it and determined that it definitely didn't come from a tree.

So he hurriedly took the hides with him, forgetting to even say goodbye to Captain Liu.

When he returned home, his family members were overjoyed to see him.
