As long as it is in a dangerous corrosion area outside the woods, flying in the sky will attract more rain.

Ning Xi spent more than an hour walking to the place where Yan Wushuang discovered the spiritual ore vein.

This is a relatively large dark mountain range, and the entire mountain range is uneven, giving people an indescribable sense of depression.

There are more than a dozen caves below the mountain range, and Yan Wushuang stood at the door of one of the caves.

At this time, Luo Yinhuang and the three also came one after another.

As soon as he approached the cave, the special ability in Ning Xi's body also jumped a few times, and he immediately sensed the fluctuation of the original stone spirit jade from the bottom of the mountain.

As soon as the people arrived, Yan Wushuang said: "There is a vein of Lingyu below here, which should be quite large, but it is too difficult to go in and mine, and the corrosiveness inside is even greater."

"Go and have a look first." Ning Xi said.

"it is good!"

Several people walked into the cave and found that each cave led to the same depth.

Going down the road in the depths, although there are no raindrops in the cave, the wall has produced a black liquid with strong corrosion, which drips little by little.

Luo Yinhuang said: "Our anti-corrosion clothing can last up to two hours in this cave, otherwise it will be corroded."

"Almost, let's investigate for an hour and a half and then leave." Ning Xi nodded.

After walking for more than half an hour, several people finally came to the end.

There is also a small cave at the end that leads directly into it, but the entrance of the cave is only as thick as a human waist, and it is impossible to walk in.

"This entrance is too small, try to make it bigger." After Di Qingyan finished speaking, he took out his weapon and attacked the cave.

But there was no response, Yan Wushuang and Jun Jiuli also joined the attack.

The current strength of the three of them is already at the eighth rank of heaven, but they cannot shake the edge of the cave even under a joint attack.

Seeing this, Luo Yinhuang also condensed his profound energy to use his sword, and the sword energy could cut off the edge of the cave, but it couldn't cut much each time.

Although it is much stronger than the joint attack of Yan Wushuang and the three of them, it is impossible to expand the cave to accommodate people in a short period of time.

Ning Xi released his spiritual consciousness, and found that from about 500 meters into the small cave, there were many rough stones of different sizes stacked or embedded in the cave.

"It's hard to get in, and the anti-corrosion suit can't last that long."

Ningxi paused and looked at Luo Yinhuang and said, "Is there any way to get a few rough stones first? As long as I get Lingyu out, I can refine some anti-corrosion pit-digging beasts and mine them."

It is too wasteful to dig only a few pieces of such a spiritual jade vein.

Moreover, it can withstand such a corrosive environment, and the Lingyu that is opened may have other uses.

Luo Yinhuang thought for a while and said, "My Tianlingsi can do it, but I'm afraid it will corrode and fail in the middle."

Ning Xi smiled and said, "I can coat your Tianling silk with a layer of anti-corrosion material to protect it. It's absolutely fine to last for half an hour."

Luo Yinhuang took out the Tianling silk and handed it to Ning Xi softly: "Try it."

Ning Xi took Tianlingsi, then took out an anti-corrosion umbrella that had been refined before and handed it to Luo Yinhuang, "Help me fight it, I'll refine it."

Luo Yinhuang opened the umbrella and held it for Ning Xi.

Only then did Ning Xi take off the anti-corrosion suit, let the dragon turtle spit out some materials, and quickly use the spirit fire to refine the heavenly spirit silk.

From time to time, water droplets would fall off and fly towards Ningxi, but they were quickly slapped away by Luo Yinhuang with the palm of his anti-corrosion suit.
