As long as it is in a dangerously corroded area outside the woods, flying in the sky will attract heavier raindrops.

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

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

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

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 below the mountain range.

As soon as the people arrived, Yan Wushuang spoke: "There is a spiritual jade vein down here, it should be quite large, but it is too difficult to go in and mine, and the corrosiveness inside is even greater." ”

"Let's go take a look." Ning Xi said.

"Good!"

When they entered the caves, they found that each cave led to the same depth.

Walking down the path in the depths, although there were no raindrops in the cave, the walls produced a black liquid with strong corrosion, dripping little by little.

Luo Yinhuang said: "Our embalming suit will last in this cave for two hours at most, otherwise it will be corroded." ”

"Almost, we'll scout 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 to the inside, but the entrance of the cave is only as thick as a human waist, and it is impossible to enter it.

"This entrance is too small, let's see if we can make it bigger." After Di Tianyan finished speaking, he took out his weapon and attacked towards the cave.

However, there was no reaction, and Yan Wushuang and Jun Jiuli also joined the attack.

The current cultivation strength of the three of them is already a heaven-level eighth-grade, but under the joint attack, they can't shake the edge of the cave in the slightest.

Seeing this, Luo Yinhuang also condensed his Xuan power to make a sword, and the sword qi could cut off the edge of the cave, but it couldn't cut much every time.

Although it was much stronger than the joint attack of Yan Wushuang and the three of them, it was impossible to expand the cave to accommodate people walking into it for a short time.

Ning Xi released his spiritual sense and found that there were many rough stones of different sizes piled up or embedded in the cave from about 500 meters from the small cave.

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

Ning Xi paused and looked at Luo Yinhuang and said, "Is there a way to get a few rough stones first, as long as the spirit jade is opened, I can refine some specially anti-corrosive digging war beasts to mine." ”

It would be a waste to dig only a few pieces of such a vein of spiritual jade.

Moreover, it can withstand such a corrosive environment, and the spirit jade may have other uses.

Luo Yinhuang thought for a while and said, "My Tianling Silk can do it, but I'm afraid it will be corroded and failed halfway." ”

Ning Xi smiled and said, "I can coat your Heavenly Spirit Silk with a layer of anti-corrosion material protection, and it will be absolutely no problem to last for half an hour." ”

Luo Yinhuang took out the Tianling Silk and handed it to Ning Xi Rouse, "Try it." ”

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

Luo Yinhuang stretched out the umbrella and held it for Ningxi.

Only then did Ning Xi take off the embalming suit, let the dragon turtle spit out some materials, and quickly used the spiritual fire to refine the heavenly spirit silk.

From time to time, water droplets would drift and fall, flying towards Ningxi, but they were all quickly slapped away by Luo Yinhuang with the palm of his hand wearing an embalming suit.
