Chen Wangping frowned and looked around. "Could it be that the black oil here leads to the sea? Where did this octopus come from?"

Xiao Fang came over and asked in surprise, "Octopus? Is it an octopus? I've heard merchants in the south talk about it before, but this is the first time I've seen it here."

Chen Wangping frowned, "Has this thing appeared here before?"

Xiao Fang shook his head. "No, the dangers of exploring the Black Oil Ruins before were mainly poison gas, black oil explosions, and the defensive counterattacks inside the buildings. These things have never appeared before. However, after seeing this thing, I recalled that when I entered the Black Oil Ruins before, I vaguely saw some unusual movements of the black oil. At that time, I thought it was the black oil flowing, but now I think it might be this thing moving within the black oil."

Chen Wangping turned his head and looked at the building in front of him.

Faced with the sneak attack of these octopuses, the fishing club and the Black Knights suffered heavy losses in just a few minutes. Judging from the red dots, one-third of their members were reduced.

These octopuses didn't seem to want to fight either. After grabbing some people and eating them, they retreated back into the black oil and disappeared.

Chen Wangping compared the situation and found that the square was safer.

The terrain here is flat, and there is the least amount of black oil residue. In contrast, in many places in those buildings, there are large clumps of black oil remaining, which is not conducive to escape and counterattack.

He turned around and warned, "This thing has definitely been living in the black oil for a long time. The square is still safer right now. Let's observe the situation here first."

Xiao Fang looked ahead anxiously and said, "But, we haven't gained much by staying here. Since these octopuses are afraid of blunt objects like sticks, why don't we gather in a group and continue exploring the ruins?"

Chen Wangping smiled and shook his head, walked to the corner of the square farthest from the entrance, took out ten oil pumps, sixty batteries and one hundred large iron barrels and placed them on the square.

The people in the Volcano Tribe were still a little confused. Some of them had been to the Black Oil Ruins before, and they didn't understand what their benefactor was doing.

There's nothing in that corner except black, smelly oil. Why go there?

Chen Wangping connected a set of wires and pointed at the battery. "No results? Come over here, a few people, help me connect the wires. Just use the same color wires. This time, if we can extract this black oil, that's our biggest gain."

Xiao Fang was very obedient. Although he didn't understand anything, he still asked Xiao Tieniu to help and they quickly connected the wires to the oil pump.

Chen Wangping glanced at the radar. No octopuses were approaching within thirty meters. It seemed their appearances were regular. He lowered the pump's inlet pipe into the oil, connected the outlet to a large iron bucket, and started pumping.

I saw the head of the oil pump slowly swinging up and down, as if kowtowing, and then it began to pump out the oil with a cool sound.

[Oil extraction in progress, current rate 5 hours]

Looking at the prompt in front of him, Chen Wangping smiled in surprise.

The extraction rate of the oil pump is calculated according to the oil reserves at the current location. If 0.05% is extracted per hour, it means there are at least 10,000 units of oil here!

These ten oil pumps can pump out fifty units of oil in the first hour!

Even if more is extracted and the rate is reduced, at least several thousand units of oil can be accumulated in the half month that the Black Oil Ruins are open!

Delicious.

Industrial blood, the more of this stuff the better.

After a while, the pumping unit had pumped out the first stream of oil.

After being filtered inside the oil pump, the oil flowing out is much purer than that outside. Although it is still very viscous, this viscosity looks bright black, and you can tell at a glance that it is of high quality.

The people of the Volcano Tribe looked at the dirty black oil outside, then turned to look at the fine oil in the large iron barrel, and discussed in surprise:

"Benefactor, this machine is also a relic machine, right? It can actually process black oil!"

"Your Excellency is truly amazing! Can this extracted black oil be used for cooking?"

"It's possible. If you were frying with lard, you wouldn't be able to fry it so quickly."

Xiao Fang couldn't listen any longer and turned around and said, "What are you cooking? You can tell at a glance that this thing is like sulfur. It must be a good material for making things. Don't be idle. Hurry and stand next to this treasure to protect it. If you see an octopus, report it immediately."

Chen Wangping waved his hand and said, "This thing is called an oil pump. You're right, this black oil is actually a very good raw material, but it's more complicated to process, much more troublesome than sulfur. For now, just collect it."

Xiao Fang nodded and looked at the black oil in front of him vigilantly, guarding against the octopus that might pop out at any time.

Chen Wangping glanced at the buildings inside the square and was a little worried about Tang Xihe. Since there were octopuses here, Tang Xihe would definitely encounter octopuses when he went to seize the refreshing potion.

Now that the spies in the team have been cleared out, he simply handed the oil pump to Xiao Fang to guard and went to check on the stimulating potion first.

Having made up his mind, he took out two armor-piercing submachine guns and ten magazines full of armor-piercing bullets and handed them to Xiao Fang. After thinking for a while, he added twenty pepper grenades and a signal flare that Tang Xihe had given him before, and instructed: "You don't need to explore other places. Just stay here and guard the oil pump. The bullets in this gun have strong armor-piercing ability. The grenade contains spicy smoke. Wait for me to come back. If you encounter a strong enemy, send out a signal flare."

Xiao Fang took the submachine gun, touched the handle happily, and shouted, "I guarantee to complete the mission, Brother Chen, you can go explore without worry."

Xiao Tieniu also patted his chest and said, "Benefactor, we are here, don't worry, no one knows the use of black oil, no one will steal it."

Chen Wangping nodded, raised his hand and spread out forty mugwort plants, saying, "Each person will receive two detoxifying plants. If you feel unwell, take one. If I'm not back by noon tomorrow, be on your guard. There will be strong winds in the Black Oil Ruins, so be prepared."

After explaining everything clearly, lightning energy surged throughout his body, and he transformed into a flash of lightning, quickly rushing towards Tang Xihe's position.

Xiao Fang excitedly distributed the mugwort and put it away like a treasure. Looking at the working oil pump, an idea came to him. He took out some black cloth and threw it to Xiao Tieniu, saying, "Tieneu, take a few people to pull the cloth to cover these. If any stray people come in from behind, they won't be able to see it."

"Okay, that heavy box next to it is really interesting. It can actually power such a big thing."

"Are you stupid? That's called a battery. I've fished it out before. It can power a lamp without burning oil. It would be great if we had this thing in our tribe."

"What are you afraid of? Just work hard and everything will be fine. Follow your benefactor and you will have everything."

"That's right."
