Before heading to Mount Laojun, Zhou Wen went to Venus.
Although the Venusian dimensional zone in reality had been destroyed and half of Venus was gone, the Venusian dimensional zone in-game still existed. Everything in the dungeon was intact.
In reality, Zhou Wen could use Li Mobai's Ghost God Eyes to lock onto the Calamity gunner's location.
However, after using the Ghost God Eyes once, they became inoperative and turned into two jade eyeballs that showed zero reaction. Zhou Wen got Li Xuan to take them back and return them to Li Mobai.
He still didn't understand why the Li family would help them up to this day.
Although his relationship with Li Xuan was indeed good, Li Mobai's various actions couldn't be explained by this relationship.
Ignoring the fact that the Ghost God Eyes were useless, even if they could still be used, Zhou Wen couldn't take them into the game. Therefore, he still couldn't kill the Calamity gunner in-game.
