After leaving the black oil ruins, Chen Wangping escorted Tang Xihe back to Huoniu City.

After returning to the outer city office, Tang Xihe put the medical equipment aside, lay on the bed, raised his eyebrows at Chen Wangping, and just as he was about to speak, his stomach began to growl.

Chen Wangping couldn't help laughing. He took out the grill and octopus tentacles, spread garlic sauce on them and started grilling.

Tang Xihe chuckled and asked curiously, "Why is this charcoal still white? This is the first time I've seen this kind of charcoal."

Seeing that the white charcoal was quite hot, Chen Wangping took out two more fish and grilled them. He said with a smile, "This is charcoal made from oak, also known as white charcoal. It has a strong firepower. You should take a rest. I'll call you when it's ready."

"Um!"

Tang Xihe nodded happily and lay on the bed to recover from his injuries.

When she was controlling such a huge fire before, her divine pool had some tiny cracks on it, which needed to be nourished with her spiritual power to be repaired.

Chen Wangping prepared the food, placed the medical equipment in the living room, and checked it carefully.

This medical machine looks rectangular, clean and without any residual black oil. It is obviously well protected, with two long tubes on the side.

Fortunately, this thing has a system light, so you can directly view the properties:

【Hemodialysis machine】

【Purpose: Remove toxins from the body】

[How to use: Just lie down after powering on, the machine will automatically calculate the relevant parameters and clear them]

[Note: This is the only intact hemodialysis machine among the hundreds of hemodialysis machines in the Black Oil Ruins]

"Hemodialysis machine? Does this mean that the soldiers in the Black Oil Ruins needed to frequently remove toxins? What was the source of the toxins?

Chen Wangping frowned. According to Tang Xihe, what were those monsters covered with tentacles that she saw?

Forget it, let’s not think about it for now. Judging from the properties of the hemodialysis machine, there should be no problem using it for Tang Huoniu.

Right now, everyone in the Spiritual Temple is hiding. I don’t know what they are researching. We have to restore Tang Huoniu’s combat effectiveness as soon as possible.

After discussing with Tang Xihe, Chen Wangping took out his communicator and called Tang Huoniu to tell him about the hemodialysis machine.

Less than a minute later, Tang Huoniu rushed over, yelling, "Hemodialysis machine? There's a hemodialysis machine in these black oil ruins?"

Chen Wangping asked doubtfully, "Uncle, do you know about hemodialysis machines?"

Tang Huoniu also saw the hemodialysis machine and couldn't help but smile as he explained, "Of course, I had inquired about it long before I was poisoned and learned about hemodialysis machines. Some major forces in the central region have one or two of these machines, but they rarely appear. I didn't expect to find one in the Black Oil Ruins. You must have put in a lot of effort to get it."

At this point, Tang Huoniu's eyes reddened. "I'm already so old, and I still need you two youngsters to help me find a way to detoxify. It's really embarrassing."

Chen Wangping waved his hand, "No, uncle, this thing has nothing to do with me, I just helped escort it back."

Hearing this, Tang Xihe stood up and insisted, "No way! If you hadn't told me there would be a strong wind, I definitely wouldn't have been able to defeat those monsters. You've made a great contribution!" After helping Chen Wangping finish his words, she asked, "Uncle, do you know how to use this thing?"

Tang Huoniu nodded, "I've learned about it. All we need to do is connect the arm. Okay, I can handle the rest myself. You guys take a rest first. With this thing, it won't take long for me to recover my strength. Then it will be time to kill those ghosts in the Spirit Hall!"

Upon hearing this tone, Chen Wangping quickly interrupted, "Okay, okay, uncle, stop talking so much and go back to detoxify."

Tang Huoniu's figure flashed and he returned to the inner city with the hemodialysis machine.

Seeing Chen Wangping interrupt, Tang Xihe asked curiously, "Brother Ping, why did you interrupt your uncle? Is what he said wrong?"

Chen Wangping had a headache. How should he explain to her the meaning of planting the flag?

The more I listened to Tang Huoniu's words just now, the more I felt like he was setting a goal.

Forget it, I won’t explain it anymore.

Chen Wangping picked up a roasted garlic octopus tentacle and handed it over, saying, "Because the octopus is roasted, come and try it."

With the delicious food in front of her, Tang Xihe didn't think too much. She took a bite of the octopus tentacles with relish, feeling the aroma of the garlic sauce, the chewiness and freshness of the octopus tentacles. She suddenly felt like she was alive again.

"It's delicious! This seasoning is delicious too. If the small octopus is so delicious, then the big one must be even better!"

Chen Wangping laughed and said, "That won't work. You can't eat the big octopuses. They've all been marinated in black oil. Only the small ones are edible."

The two chatted and ate, and soon finished two octopuses and two fish.

After eating and drinking, Chen Wangping noticed that Tang Xihe's face was still a little pale, and asked worriedly, "Why do you look so bad? Were you injured in the medical department?"

Tang Xihe explained how his divine pool had been damaged, and specifically warned, "If you see lightning in the wild, don't try to control it. The divine pool has boundaries, and if you manipulate elements beyond your control, problems will arise. I heard that a level five senior once tried to control the volcanic flames at the crater, but his divine pool was broken and he died on the spot."

Chen Wangping understood and nodded to take note of it.

Knowing the problem makes it easier to solve it.

He flipped his hand and took out the iron ball, then took out half a jar of the god-summoning potion and poured it in.

Tang Xihe looked a little puzzled, "Brother Ping, is this iron ball some special treasure?"

Chen Wangping smiled and said, "It's not an iron ball, but when it's paired with the bullets I visualized, it becomes a treasure." He then took out a few expired thunder and electron bullets, vibrated them, and fanned the mist from the iron ball into Tang Xihe's mouth and nose. He then warned, "Absorb it quickly, and stop when you've had enough."

Tang Xihe took a breath and immediately felt that his cracked divine pool was nourished. His originally heavy mental strength became lighter and his injuries improved immediately.

Brother Ping is so awesome!

Is there such a use for the imagined lightning bomb?

She nodded as she took out the six jars of spirit-summoning potion she had obtained last time and placed them on the table. "Use mine first. Your own spirit pool hasn't even been filled yet."

Chen Wangping was not polite either. He moved his hands quickly, continuously creating mist for Tang Xihe to repair her injuries.

An hour later, Tang Xihe finished drinking three jars of the spirit-summoning potion. His complexion finally looked better, but he was so tired that he felt sleepy.

Chen Wangping put away the iron ball and said, "Have a good rest. We'll talk about it tomorrow."

"good!."

Seeing that Tang Xihe was fine, Chen Wangping packed up his things and turned to rush to the base.

Let’s go home and see the oil refineries and chemical plants!

I don’t know what the current technology tree can produce with oil.
