This was Bai Chen's first time revealing his ultimate goal to someone after transmigrating into this world, but he didn't feel worried because he didn't even tell Zhu Ge that the goal was part of the mission Bai Lang had given him.
He remembered the rules that Bai Lang had given him, and he knew that he would be fine as long as he didn't reveal the truth that he wasn't the real Bai Chen in this world, and he just transmigrated to this world and used Bai Chen's body to complete the mission.
He had just learned the truth that the real Bai Chen of this world had died because that man had committed suicide for reasons that remained unknown to him, but he knew that he could not reveal the truth in front of Zhu Ge.
