Although Leon wanted to see that until they collapse of exhaustion, Leon felt something weird. Everyone's mana was calm until now, but Leon felt two presences getting agitated... much to his surprise, each side had one of those presences.

"I guess I wasn't totally wrong..."

Leon used Transfer and appeared behind a Japanese soldier that was concentrating his mana in his right hand. Leon grabbed him by the neck and sucked his mana using Mana Absorption. Several soldiers panicked when they one of them losing control over his body when Leon appeared, but he ignored them and used Transfer to grab one of Gisela's soldiers by the neck and did the same thing. Yuki and Gisela only stopped fighting when Leon appeared in the middle of the arena and started to hit the soldiers like hammers against the arena. In the end, Leon only stopped when the place was totally destroyed, and he was striking the soldiers against the ground.

"Phew... that was refreshing." Leon left the half-dead soldiers on the floor and then stretched his body only to find everyone, even Yuki and Gisela, pointing their weapons at him. "Calm down guys, let's not do anything hasty."

Why did you do that?" Ren asked.

"Those guys were planning to attack Yuki or Gisela, maybe both," Leon answered. "They are powerful fighters, after all. Their deaths also would cause instability in both groups. Do any of you guys remember when they joined your armies? "

Gisela looked at Lennart, and he just shook his head, the same thing happened to Yuki and Ren. However, some soldiers stepped forward and mentioned that they joined their sides, just after the battle when the terrorist camps had been destroyed.

"What were their positions in your cities?" Leon asked. "Where they close to any of you?"

"... That soldier was one of my advisors," Yuki said. "Are you sure he was preparing to kill me?"

"I felt a massive amount of mana being concentrated in his right hand," Leon answered. "What about the other guy?"

"... He was just an ordinary soldier that protected our walls," Gisela answered. "However, he talked to me many times about returning to Earth, and he was also the number one person who wanted to reconquest our lands back using brute strength."

"There you have it, it is evident that they worked for the terrorists," Leon said. "They were quite the patient bastards... a bunch of assholes that had the patience to wait for three hundred years to kill the human leaders... crap."

"I guess you guys can understand that until now, someone has been working behind the scenes to put the humans in a bad spot," Leon said. "I know that you won't be able to forget your grudges soon, but it isn't time for that. In forty years, powerful beings will come to Earth and kill every single human to get stronger. Don't waste your time fighting against each other; save your strength to fight against them."

Leon didn't wait to see Yuki and Gisela's reactions; he just left and headed toward the hippogryphs' world. If they still decided to fight after hearing that, then humans were doomed, and Leon could only give up.

"Shit... I hope that is the last time those bastards will cause me so much trouble."

If Hector convinced the other survivors to return to Earth, Leon would have a hard time finding the possible spy infiltrated. Besides, his presence had already been revealed by every single person there. So, at any moment, something might happen.

A few hours later, Leon arrived at the entrance of the hippogryph's dungeon. He arrived in time to see hundreds of people leaving the place. Since it was dark, Leon didn't notice, but it looked like Hector, and other soldiers cleaned the area of monsters, and now the general population of his city was finally returning to Earth.

"Shit, I won't be able to use Appraisal in every single person like this... now that I think about it since those guys infiltrated Gisela and Yuki's camp, it will be impossible to identify them because they probably don't have those spells to make other humans explode."

Fortunately, Leon found the new camp pretty close to the dungeon. It was a bit reckless, but given that the soldiers fought against that kind of creatures for hundreds of years, they would handle. Their problem was the lack of fighting spirit, not real power.

Leon knew that trying to find a possible infiltrated agent would be close to impossible, but he had no other choice but to try, at least for a while. Maybe there was a chance that a spy didn't infiltrate Hector's camp, but Leon couldn't just hope for that and do nothing... until the last person crossed back the portal to Earth he used Appraisal in every single human...unfortunately, he found no one strangely powerful.
