The coordinates at which the previous space patrollers found the alter were in the hands of the Immortal squadrons.
They bought it from the government exclusively so that no one else would be able to learn of it.
Oscar, on the other hand, was a sacred demon who worked for the government and also a high ranking personnel in the intelligence department, so most of the important information given to the government, military, and his superiors passed through his hands, and as a result, the coordinates of that alter were known to him and he had even made it known to Yao Wang and the Mo twins.
"Team 345 sent the coordinates of the alter to earth, but our staff mishandled it and lost it."
Because of this, we have to search for it afresh. Don't forget, we're up against a demon that has killed our comrades in the past, so don't let your guard down even for a second, because this old man is the only one allowed to die and not you."
