Step by step, approaching the black lake, the windless lake surface is terrible and quiet without any turbulence.

Yang Yu grabbed a stone casually and threw it towards the center of the lake. The waves caused by the waves spread across the lake. It seemed that there would never be any strange things coming out from under the lake.

But, it may also be just a manifestation.

The corrupt individuals that Kaka counted were only involved in sealing the infected and alienated goblins. When the disaster occurred, the devoured goblins could not be counted. There were more than 50,000 goblins living in the goblins' country. It was too difficult to check one by one and confirm the whereabouts of unknown goblins.

This also means that Yang Yu and the others do not know how many enemies there are on this land and how many cores they need to deal with, but they know that there are definitely more than four that are as simple as four.

He took out the scroll given by Kaka and Yang Yu opened it to Bai Jin for research.

The scroll given by Kaka is similar to the magic scroll. The energy contained in it is extremely huge. As long as magic is injected, the magic array can be activated and sealed. Its only disadvantage is that the magic array is too complex and requires a certain amount of activation time.

According to Bai Jin's estimate, it will take at least three or four minutes to start the time.

The scroll needs to be placed in the center of darkness to play its best.

The question is, where exactly is the center of darkness?

Yang Yu couldn't make a judgment, nor could he make a judgment. Even if he went back to ask Kaka now, he didn't know if he would get an ambiguous answer.

"Oias, you have read so many books these days. Where do you think the center of the darkness is? Is it a huge black bubble hanging in the air, or a lake where tiny bubbles appear quietly in the center, or some other place?

”

Yang Yu's sudden question surprised Eias. A flame suddenly ignited in her heart. After reading so many books and learning knowledge, she finally had the opportunity to come in handy. Today she would let Yang Yushi stay away for three days as if she was impressed.

Taking a deep breath, taking another deep breath, Oias sorted out his thoughts in his heart and answered firmly:

"I think it should be the black bubbles that are the center of the darkness."

"Why do you feel this way?" Yang Yu asked.

After some brewing, Oias said seriously:

"The black shadow was knocked down and turned into black gas again, and it merged into the bubbles. Even the bubbles that kept floating out of the lake merged into the huge bubbles.

Everything revolves around that black bubble.

The constant emergence of small black bubbles on the lake surface seems suspicious, but if you think about it carefully, you will find that it is not the center, but the source.

What we need to do is to find the dark center. If we do not seal the center, but seal the source, what should we do if the black gas flows outward? I don’t think such a huge black gas will completely disappear in a short time. On the contrary, I think these black gas may run wild because of the loss of the source."

"Well. What you said makes sense. You haven't read the books you have done these days in vain. You have some of your own opinions. As for whether it is right, it has to be said differently."

Hearing Yang Yu's lukewarm words, Oias bulged her cheeks with some dissatisfaction. She finally sorted out her thoughts and said a point that would convince her, but she didn't expect that Yang Yu had no reaction at all, as if she hadn't listened carefully.

"What do you think?" Ias asked angrily.

"Basically, it's similar to what you think. One thing needs to be added. This has definitely happened more than once in the past. No corresponding protection has been established here, which means that the source may not only appear at the bottom of the lake, but also at some other places.

I don’t know whether intentionally or unintentionally, these darknesses have a certain sense of self-protection, but they don’t seem to be conscious at all, and tend to be more instinctive.

Perhaps, the huge black bubbles hang in the air just to prevent anyone from getting close to the core instinct.”

"So how to explain the rupture of the black bubble?" said Oias. "If you want to protect the center, why do you choose to self-destruct?"

"Who knows, maybe, it's just that the priority of self-destruction spreading darkness is greater than the protection center, just like a migratory salmon that will give their lives to produce seeds."

Yang Yu shrugged and finally asked what he was most concerned about.

"Ias, now tell me, just by your intuition, where do you think the center of darkness is?"

"Intuition... I still think it's that huge black bubble. I can sense that the black bubble contains trembling darkness, just as if I want to swallow the whole world."

Oias said what she thought. If Yang Yu and Bai Jin were not beside her, she would have turned around and ran away long ago. But somehow, looking at Yang Yu and Bai Jin who were completely different from her, she would have inexplicably felt a sense of courage in her heart, as if she was with her family.

Yang Yu pointed to the black bubble, "Okay, then make sure, put this scroll in the center of the dark bubble."

After determining the destination, what should I think about now is how to put this scroll firmly into the black bubble.

If they were magicians sent by the Library of Everything, they could easily fly up the sky with flying magic and send this scroll to the center of the black bubble.

There was no one between Yang Yu and the others who could fly, and there was no guarantee that after getting close to the black bubble, no other corrupted person came out of the bubble and caught them off guard.

You have to ensure your safety while ensuring your approach...

Thinking of this, Yang Yu looked at the calm lake and looked at some of the materials in the system. It seemed that it was no problem to make a small boat.

"We make a small boat and try to get close to the black bubbles. If something pops up from the black bubbles, we can also react in time on the boat. Even if the boat capsizes, we can swim back, as long as any corrupters in this lake..."

As soon as Yang Yu finished speaking, a huge black shadow spread his bloody mouth and rushed towards Yang Yu.

He pushed Bai Jin and Oasi backwards and picked up the shield, used the shield to block it to meet the bloody mouth. With a "click", the bloody mouth instantly bit Yang Yu's shield, and his sharp teeth made a red mark on Yang Yu's arm.

Is the shield block invalid? Is the attack of the shield block missing?

The surprise for a moment did not stop Yang Yu's movements. He inserted his sword into the black crocodile's mouth, used the gap between the black crocodile's teeth as a fulcrum, pried open the crocodile's mouth, pulled out the bleeding right hand, and rolled backwards.
