The soil is only contaminated during the death period and is easily purified.

It is easy to purify Ning Caichen and can also be converted into spiritual energy for use.

The purified one suddenly released and immediately became contaminated.

"Have you ever investigated the reasons why it is impossible to plant here?" Ning Caichen said seriously.

"After investigating, it was mainly because there was a light curtain underground, and the dead air spread out from the light curtain." Meng Xi said seriously.

"Why don't seal the pearl light curtain so that it won't cause large-scale pollution." Ning Caichen asked in surprise.

"These death energy has the function of corroding. Every year, the array plate must be built and arranged again. The strongest metal will also be corroded, so a large amount of expenses are required every year. Moreover, if the magic array is close to the eyes, it will not last for a few days. Therefore, relying on a large-scale package, keeping the array plate away from the eyes." Meng Xi said endlessly.

"And every year, a large number of people need to collect and purify suddenly?" Ning Caichen asked in surprise.

"Yes, whoever can purify this place will belong to whom, and there will be a bonus of 100 million amethyst coins." Meng Xi looked at Ning Caichen with beautiful starry eyes, hoping that he could solve the problem here.

"Where to see the light curtain?" Ning Caichen said in contemplation for a while.

"Walk over, otherwise my car will be corroded and I will not be able to drive the light curtain anywhere." Meng Xi said with a wry smile.

Ning Caichen walked for a day before he saw the mysterious light curtain.

It is a lake full of water, with a light curtain inside the bottom of the water.

The aura of death is filled with black at any time.

Because the light curtain is too strong, it will penetrate the water surface, and you can see the door of the light curtain deep in the water on the shore.

The aura of death continued to spread out from the light curtain, first passing through the lake and then spreading out.

A huge magic circle covered 100 million acres of land, and the entire sky was black.

I can’t see the sunrise and sunset, but I am surrounded by dark clouds. The dark clouds are the aura of death. Every year, many cultivators come here to clear the dark clouds.

This is a faint layer, which means that it has just been maintained for a while.

"The Lord of Sunset City has spent a lot of manpower and material resources to expose the death energy here, and the spirit gathering array here is higher than the spirit gathering array in the city." Meng Xi said.

Ning Caichen's spiritual consciousness spread out, touched the light curtain, and sensed an aura of extremely dangerous and fear. This aura was very familiar.

"Is the light curtain the world leading to the light?"

Ning Caichen was shocked in his heart!

Because the aura of death that permeates the light curtain is actually the aura of sound.

No matter how stupid you are, you will judge that the light curtain is the door to the world of voice.

Everyone is afraid of sound. After all, you can’t see terrifying things that can kill people, so it would be strange if you are not afraid.

Ning Caichen thought of extracting some water into the inner universe.

After experiments, neither high-level alchemy materials nor porcelain peeling can resist the corrosion of death.

The main thing is to cover the light curtain so that the air of death can be blocked. The air of death can be wrapped and not emitted, and it can be purified regularly.

The problem is that no metal or object resists the invasion of death.

Mengya is asleep, but the smart computer can still be used.

There are also a gathering of billions of wise men in the inner universe to discuss solutions to these death auras.
