Lu Ning frowned immediately and asked, "What happened?"

"Multiple cracks have appeared on the Earth's barrier at the same time. I've never encountered this situation before. Although the evil gods are still unable to enter the Earth, those cults have probably been doing a lot of things in secret."

Lu Ning's heart sank when he heard this.

Having experienced the previous phantom of the Hand of the Underworld and the subsequent cracks in the disordered time insects, he knew how dangerous it was for the barrier to crack.

The simultaneous appearance of several cracks would inevitably lead to a significant increase in the density of fog on Earth.

He said calmly, "Then let's go back and close the crack first."

Lu Ning had originally planned to continue tempering his spiritual power here, but now it seems he will have to go back.

Yan Bing, Ya En, and the other two nodded.

Osiris said, "That's what we thought too, so we're waiting for you here."

Lu Ning nodded: "Let's go now..."

He paused for a moment, then looked at Yan Bing and asked, "Yan Bing, do you have a high-risk soul weapon?"

Yan Bing shook her head: "No, what's wrong?"

Lu Ning said, "Then wait a moment. Give me the soul weapon you're currently using, and I'll help you upgrade it to the extremely dangerous level."

Everyone was taken aback upon hearing this.

Then they realized something, and Yann exclaimed in surprise, "You can now materialize extremely dangerous level Horcruxes?!"

Lu Ning nodded: "Yes, do you need it?"

The three of them, Yan and his companion, exchanged glances and shook their heads.

"Forget about us. Our strength is not enough to support a soul weapon of this level. If we force it, we will probably be killed by the side effects. It is better to use a high-risk soul weapon."

Yaen's words were exactly what Lu Ning had thought before.

Aisalind, who had been silent until now, suddenly said, "However, you can help me materialize some extremely dangerous, single-use hazardous materials that are suitable for our use."

Yann and Osiris's eyes lit up as well.

"That's a good idea!"

Dangerous goods are, after all, disposable. Although the side effects are equally significant, at least they are not fatal.

Lu Ning nodded: "I'll materialize some extremely dangerous, single-use hazardous materials with relatively low side effects."

"That would be perfect!"

Lu Ning looked at Yan Bing, who immediately took off the blue bracelet from her wrist and handed it to Lu Ning.

Lu Ning suddenly remembered An Lan's previous introduction of Yan Bing.

This seems to be the soul artifact that Yan Bing used before, called the Ice Demon Bracelet.

After receiving Yan Bing's bracelet, Lu Ning and his group immediately left Yan Bing's room and headed back towards the Tower of Return to the Ruins.

Although the situation on Earth is probably very urgent right now, sharpening your axe won't delay your work.

With a large quantity of one-time-use, extremely dangerous items, and Yan Bing acquiring an extremely dangerous soul weapon, their combat strength would be significantly enhanced, which would obviously be beneficial in closing the rift.

Moreover, it doesn't take too long to materialize these things.

Lu Ning entered the Tower of Return to the Ruins, while Yan Bing and the other three waited outside.

After entering the Tower of Return to Nothingness, Lu Ning did not delay and immediately began to materialize.

To expedite the process, Lu Ning's mental power was only used to leverage the power of the Tower of Ruins; the vast majority of the energy used was replaced by the energy within the Pale Crystal.

This also made Lu Ning's mental energy consumption much slower, and made it quicker and more convenient to materialize items.

Lu Ning first upgraded the Ice Demon Bracelet to the extremely dangerous level, which cost him about eight thousand Pale Crystals.

After that, Lu Ning began to materialize one after another extremely dangerous, single-use items.

Lu Ning was considering that not only could the three of them, including Ya En, use these items, but also a large number of Saints in the Mist Bureau could use them.

Therefore, Lu Ning not only manifested dangerous items corresponding to the abilities of the three Ya En, but also some dangerous items with other abilities.

Lu Ning's requirements were simple: fewer side effects, or even less potent effects, would be acceptable.

After all, if the side effects are fewer, it might be possible to use it more often.

As long as the quantity of disposable hazardous materials is sufficient, it's fine.

Since it is a single-use, extremely dangerous item, it does not require a large amount of Pale Crystals. One item can be manifested with only about one hundred Pale Crystals.

If Lu Ning were to materialize all the pale crystals into extremely dangerous, one-time-use hazardous materials, he could even materialize tens of thousands of them!

Of course, Lu Ning would never do that.

He only spent around 100,000 pale crystals to materialize a thousand one-time-use, extremely dangerous items.

The sheer number of extremely dangerous materials gathered together created a mental pollution so intense it could even manifest as a fog.

However, such mental pollution had no effect on Lu Ning.

After collecting all the single-use, extremely dangerous items, he planned to leave.

Just as he turned around, he paused, suddenly remembered something, and once again used the 500,000 Pale Crystal to materialize the transparent spiritual liquid he had previously materialized.

This transparent spiritual liquid only requires a single piece of pale crystal to materialize into one bottle, and Lu Ning materialized a total of 500,000 bottles.

His idea was simple.

That is, since the barriers on Earth can now develop multiple cracks at the same time, and it has only been less than a year since the last crack appeared.

This indicates that the barrier is becoming increasingly fragile.

Lu Ning felt that even if the crack was closed this time, it would probably reappear before long.

He planned to temper his spiritual power on Earth after closing the rift this time, and not go to the Ruins of Return.

Even if cracks appear again, he can help immediately.
