章節 129: The Foundation of the Profound Empire

[Imperial scientist]

[Mission description: The Phantom Goddess was once the princess of the Profound Empire. She has entrusted you to kill the once strongest scientist of the Empire, Shelt. His physical body is dead, but his soul is still alive.]

[Mission Nature: only hidden]

[Mission difficulty: 5 billion]

[Mission details: Clear the secret land, the Empire's first research institute, and kill Shelt.]

[Mission reward: ???]

[Hint: there are countless dangerous traps in the empire's first research institute. Please, proceed with caution!]

Li Cheng was done reading the mission information. Even he could not help but be a little surprised. The difficulty of this mission was actually five billion!

One had to know that even returning to the Eight Gods Mountain, which was home to the green-skinned monster, was only eight billion in difficulty. This made Li Cheng wonder, 'What kind of terrifying existence is in this research institute?'
