The people who were mining were still a little strange, but when they heard the mayor speak, they put down their work, ran out of the entrances of the cave, and ran behind Chen Wangping.

In just three minutes, Xiao Fang counted the number of people and reported to Chen Wangping: "Brother Ping, all of them have been withdrawn, but what happened?"

Chen Wangping handed him a towel and said, "Is it hot?"

Xiao Fang wiped his sweat and suddenly realized it. He immediately called his own people from the volcanic tribes to come over. While using his superpowers, he lay on the ground to feel it.

I saw strands of sulfur mist escape from them, and then spread to the ground along the gaps on the ground, constantly conveying information.

Chen Wangping was not idle either. He took out the mineral detector and avoided the crowd to observe carefully.

From the light and shadow of the mineral detector, the ore veins below did not change much, and no signs of a volcanic eruption were seen.

Strange, what's going on with this temperature?

After a while, Xiao Fang stood up strangely, discussed with the people next to him, and said to Chen Wangping: "Brother Ping, based on our experience, the volcano below should have recovered."

Chen Wangping asked: "It's revived? Will it explode?"

Xiao Fang shook his head and said, "This is not a good thing. If you recover, it is actually the slurry under the volcano has started to flow again. However, whether it will erupt ore is necessary. However, as the current situation is, this is beneficial or not for us. Since the volcano flows again, it is possible to rush some strange ores to the upper layer of the mine cave and mine them all the way, and you may harvest good things."

Chen Wangping frowned, "Is it very dangerous? I don't know much about volcanic eruptions."

Xiao Fang explained: "The danger is not great, because there is a process for volcanic eruption. I will not blow it up just by saying it. Next, I will arrange for experienced tribe members to take turns to guard here. Once I encounter it, I will immediately call for people to evacuate, which is still time."

Hearing this, Chen Wangping breathed a sigh of relief. Fortunately, it was just a recovery, not an eruption.

Otherwise, let alone Fangshan Town, even Leilong City would be greatly affected.

He looked back at the miners, thinking that since they had called out, he might as well have a half-day vacation and let them rest.

After sending away the miner, Chen Wangping arranged for Xiao Fang to go back and throw the sulfur mine onto the production line.

Just as he was about to go back, Tang Xihe pulled his clothes and whispered: "Brother Ping, the fire element here is a bit special. I want to practice here."

Chen Wangping looked at the scent of sulfur all around him, took out the fossil of mugwort and handed it to her and said, "You can practice. Take this with you. Let's go in and take a look. I'll dig some sulfur mines too."

The two entered the sulfur mine, and the temperature here was higher than that outside.

Considering that the fire element escaped from the ground, the two rushed directly to the bottom of the mine, which was a depth of 800 meters from the ground.

When I got here, the air I breathed was extremely hot, which was a bit unbearable.

Fortunately, along the way, Tang Xihe was gathering the nearby fire elements and constantly lowering the temperature.

After arriving at the position, Tang Xihe closed her eyes and devoted herself to the cultivation.

Chen Wangping first took out the power mining machine, connected the circuit, and then chose the sulfur mine next to it to create it.

But at this time, a line of prompts appeared on the power mining machine:

[The current temperature is too high, the durability loss is doubled. Please lower the temperature or use special mining equipment]

“Special mining equipment?”

This is the first time Chen Wangping has seen this term, but it is easy to think that it should refer to equipment that can operate in special environments. For example, if the temperature here is too high, mining machines made of ice iron ore will definitely be more suitable. If you go to the thunder pool to mine, you must use thunder iron to make equipment.

The plan is easy to come up with, but it is just this resource, it is too difficult to get it all together.

It's better to go on it yourself.

Usually the mines above are enough for ordinary power mining machines to mine.

Chen Wangping took out the mine pickaxe and digged it at the sulfur mine next to him.

"Bangbangbangbangbang"

The pickaxe waving, and the sulfur ore fell.

He picked it up and checked the properties and found that the sulfur ore here is of higher quality, and any digging can reach the level of [sulfur ore☆☆].

"The worse the mining environment, the more good things must be."

Chen Wangping put away the ore and dig it hard.

Mining time always passes quickly.

Five hours later, his storage compartment was filled with a full set of sulfur ore, and even hollowed out the surroundings.

Just as I was about to rest for a while, a light suddenly flashed in the afterglow.

Chen Wangping turned his head and saw a fiery red light coming from the root of a mine that he had dug before.

He walked over and aimed at the light and continued to dig.

"Bangbangbangbangbang"

After three strokes, the remaining mineral points shattered in response to the sound, revealing their true faces of light.

It turned out to be fifteen red copper ores, with circles of strange patterns that looked like annual rings.

【Central of Earth Modified Copper】

【Purpose: Create acceleration equipment】

[Special effect - Earth-center annual ring: Earth-centered copper has gone through time, which can greatly improve the production efficiency of the equipment and has the chance to enter the Earth-centered acceleration state]

[Special Effect - Earth-Central Acceleration State: After entering the Earth-Central Acceleration State, the efficiency of the instrument will be greatly improved while sacrificing durability]

【Note: This is a treasure from the center of the earth】

"Earth-center annual rings? Metal ores also have annual rings?"

Looking at the properties of this thing, Chen Wangping immediately thought of how to make the best use of it.

Make it into a circuit board and an integrated circuit board, and then into a speed plug-in.

In this way, plug-ins can be used flexibly, improving the efficiency of creating various devices.

Just do it.

At this time, Tang Xihe also opened her eyes, her face turned red, obviously absorbing a lot of fire elements, "Brother Ping, you go back first, I will continue to practice, don't worry."

Chen Wangping took the space device full of food and handed it over, nodded, left the mine and returned to the base.

He first arranged the molten copper in the center of the earth according to the previous idea, and then walked to the secondary mechanical crystal manufacturing platform to check the situation.

The number is already one hundred.

He skillfully called out the technology tree and aimed at the production technology to be upgraded.

But after seeing this, he realized that production technology is already intermediate, and the next level requires 500 secondary mechanical crystals.

I glanced at the technology tree and saw that the collection technology had not been upgraded yet, so I might as well upgrade the collection technology first.

One hundred secondary mechanical crystals were invested, and the technology tree shone with a flash, and brand new drawings emerged.

【Congratulations on successfully upgrading the intermediate collection technology】
Chapter completed!
