Time Traveler Chat Group: What do you mean, I opened it?

Having transmigrated to the world of Ling Cage, Chen Sheng finally managed to build a career with his cheat-like abilities. However, the apocalyptic world was sparsely populated, and the life growth limit was locked. Just as he was racking his brains, unsure of how to choose and accelerate his own civilization's progress, a chat group for transmigrators suddenly appeared before him. A transmigrator from the mythological world: "Big shots, help! I just transmigrated and the gods have already discovered me!" A transmigrator from the Warhammer world: "Requesting support! We just successfully rebelled, and the Imperial Guard has already arrived." A transmigrator from the mortal world: "The Crimson Forbidden Land is about to open, brothers, can you give me some points to accumulate…?"… Upon seeing this, Chen Sheng's eyes lit up, and he immediately opened his arms to all the worlds. "Everyone, do you need cross-world diplomacy and political asylum?" "Weapon support is also possible! Artificial ancient gods, interstellar orbital cannons await in the starry sky!" "What?" "You're asking about the cost?" "The cost isn't high; just open the door to your world!"
