After fighting Rein for some time, Alcusus immediately retreated when he was unable to gain any momentum even after fighting for so long. His second skill was very powerful and it could find gaps and flaws in others techniques. But against Rein, it was not very useful as he revealed almost no gap. Whatever flaws Alcusus was able to observe were intentionally left behind by Rein to lure him.
So Alcusus thought that the more he fought this human, the more danger he would be in. So after becoming sure that he had no chance of winning in a short time, he immediately pulled back. Currently demons and humans were in a stalemate but time was on the demons side. So Alcusus showed no need to take unnecessary risks.
The damage to the demons side in the last battle was greater than the humans so this battle could be considered a victory on their side. But none of the humans were happy about it. That was because the result of that battle was actually insignificant in the grand scheme.
If they could not enter the spatial rift and get rid of the demons at their source, any kind of previous victory no matter how big or small would become useless.
But taking advantage of the fact that the spatial rift was like a home to them, the demons were able to successfully get rid of the humans every time they tried to open a passage.
So to solve this problem, Rein then suggested another plan. It was a risky plan but in this stage, some risks were inevitable. So all the humans agreed to the plan almost immediately.
What Rein was planning was very simple. Just as the demons were stopping the humans from entering the spatial rift, now the humans were also going to block all the exits of the rift.
After researching so many nodes, some human experts of the spatial laws had managed to find a way to detect the spatial nodes even without knowing the coordinates, so basically humans had managed to at least find most of the nodes. Even though the insides of the spatial node had an ideal environment for cultivation, other than that there was nothing.
The human side had expected something like this to happen so they immediately counter attacked in full force. During this mayhem, Rein was actually able to kill one of the demon gods which made the demon's situation even more dire.
...
After this same thing happened for a week, Alcusus tried the deplomatic approach for the first time. Without the supply of the world's energy, all the demons were on the verge of getting their cultivation level dropping. Even he himself was somewhat affected by it.
The higher the cultivation, the more world's energy that person would need. So having the highest cultivation among the demons, Alcusus' condition should have been a lot worse. The only reason that was not the case was because the spatial area where he was training and had gotten his second skill was capable of producing a little bit of the world's energy.
That amount was not enough to sustain his full needs but at least it was a stopgap measures.
Currently the humans had no need to acknowledge any request from the demons and Alcusus knew that. So he was trying to threaten that if the demons were pushed to the limit, then instead of slowly losing their cultivation, they would prefer to self destruct their cultivation base to kill as many humans as possible before dying.
This was not something impossible. Demons had always been chaotic and doing something like this was very much possible. So after having an internal meeting, humans agreed for a discussion. But obviously with their superior position, they were not going to accept this request so easily.
So the humans demanded that they would only accept this proposal if the meeting was held inside the spatial rift and humans were allowed to enter it.
This was a risky decision as the people who would enter the spatial rift would be in huge danger if the negotiations broke down and the demons tried to attack them. But this was definitely the best opportunity for them to enter this spatial rift so there were many humans who were willing to sacrifice themselves for the greater good.
