I'm creating a crisis in Jinjuli

Suddenly, Alan's face changed drastically as if he realized something, and he shouted loudly: "No! Captain Erwin, we must leave here quickly, this place is about to..." However, before Alan finished his words, the ground began to shake violently, and then a dull bang was heard, and the entire ground began to collapse.

"Get out of here quickly," Jean said quickly.

…………

After running for a while, everyone finally arrived at a relatively safe place. They stopped panting and stared nervously at the forest not far away. There, a mysterious black cave was constantly emitting billowing black smoke.

The black smoke was like a giant python, twisting and circling in the air, as if showing them its power and majesty. It continued to rise from the cave, dyeing the surrounding air dark, making people feel an indescribable fear.

The uneasiness in everyone's heart became stronger and stronger. They stared at the black smoke, as if they could sense some kind of evil existence from it. The black smoke seemed to have life, spreading in the forest, devouring all vitality and light.

Someone whispered, "What on earth is this thing? Why is it here?"

At this time, Erwin looked at Allen and Jean, "Jean, I'll leave this place to you." Allen said and ran away.

"Hey, wait Alan, I don't know the whole process?" Jean shouted, but Alan had already run far away.

Then, in front of everyone, Jean told everyone what happened after he rescued Alan.

"In other words, Eren can now maintain the void form?" Levi asked.

"Levi, is it time to talk about the void form now? Look at that..." Everyone looked at the black hole that was constantly emitting black smoke and swallowing the surroundings.

"It's true that if we don't solve that thing, we'll all be doomed." Erwin said.

"About this..." Lance spoke at this time.

"In fact, after some research I just did, I found that with the mass of that black hole, it is completely possible to break through the barrier of the special field created by Chronom." Lance said.

"What?" everyone said in surprise, and then Lance said a lot of words (I'm too lazy to make them up). Although I didn't understand them, the meaning was that this black hole could be used to break Chronom's time barrier.

"That being said, that thing..." Hanji looked at the expanding black hole. "It doesn't look like it can move to the primeval forest by itself, does it?" Hanji said. "And we are not sure where Chronom is now."

"I have an idea?" Max suddenly grabbed Jean's body and spoke.

"What method?" Hanji asked curiously.

"We in the Kingdom of Light have a forbidden technique that was originally used to seal things, but if we control it a little bit and don't seal it, we can use that technique to move the black hole there." Max said.

"I can find out about that area," Allen came over, "As long as I transform into a void form, I can sense the abnormal space around me, and then I can force him to appear."

"There won't be any problem with this one, right?" Levi asked.

"Actually, there is one more," Max said again, "The move I mentioned requires at least four Ultra Warriors to perform, and the whole process cannot be interrupted, even if Reiner is included. But if Eren senses it at that time, he may need to take the initiative to attack. But after all, we are indeed an Ultra Warrior." Max said.

"How about I help you?" Everyone looked in the direction of the voice and found that the person coming was Kirisaki.
