Seven Lù said, "The specifics still need rigorous Data Analysis before we can reach a correct conclusion."
"However, judging roughly from the reactions of these Zerg Nest Builders, they should be similar to Oxygen-Tolerant Bacteria."
"In other words, they do not depend on oxygen, but they can survive in an oxygen-rich environment and will not be killed by a certain amount of oxygen."
"However, if the oxygen concentration is too high, it can still suppress or kill them."
"...This time, Master pumped nearly one hundred percent oxygen into the next room. That definitely exceeded the range of oxygen they could withstand."
"The oxygen content in the Beichen Galaxy is only twenty-two percent. Even if they do not breathe oxygen, they can still survive without any side effects."
"So they can survive normally on Habitable Planets in the East Tianyuan God Country, the Ximanielli Federation, and the Southern Cross Star Kingdom."
"But once the oxygen content in a certain space approaches one hundred percent, they cannot endure it and will certainly die."
"However, this method only works in enclosed environments."
There was a hint of regret in Seven Lù's childlike voice as it said, "Because in open areas, no matter how much oxygen production is increased, such an oxygen concentration cannot be achieved."
Xia Chujian understood. She said regretfully, "That's true... Still, this is a way to guard against Zerg Nest Builders lurking in hiding."
Seven Lù said, "First seal off a room, then fill it with oxygen until it reaches one hundred percent?"
Xia Chujian said, "The cost of that should not be too high, right?"
Seven Lù said, "If Master goes to Southern Cross Star, you can try it there."
Xia Chujian sighed. "If even I have gone to Southern Cross Star, that means humanity's war against the Zerg
