In fact, before the bloody shadow appeared in the corridor, Chu Yunsheng had already noticed it. The abnormal energy fluctuation in the surrounding did not escape his detection at all.
It was indeed very strong. Its energy fluctuation was not weaker than anyone in the corridor.
But it was also very weak, as weak as a fragile vase. However, its weakness was hidden behind the dimensional barrier, existing in the fourth dimension. That was why it was strong in the three-dimensional world.
If Chu Yunsheng didn't count the black shadow that he had encountered on the island, this was the first monster that Chu Yunsheng encountered that was able to keep its life in the fourth dimension. As long as the fourth dimension was not destroyed, its zero-dimensional space would not collapse.
And in terms of this monster, it was no stranger to Chu Yunsheng. In fact, he knew this type of monster a long time ago.
