In 2030, an anomaly transpired, and aliens invaded the earth! At this age where the world was about to be destroyed, the top talents of mankind gathered from all over the world to develop a holographic game called Miracle. All humans on Earth would enter this game and battle against foreign invaders through holographic simulation. After Mike entered this game, he unexpectedly discovered that he could actually see all kinds of hidden information.

[Beginner-tier Exotic Beast, Level: 1, Status: Weak…]

[Boss-tier Exotic Beast, Level: 10, Status: Berserk...]

[Overlord-tier Exotic Beast, Level: 15, Status: Idle. Will drop a piece of SSS-grade weapon when killed... ]

[Old wooden crate with hidden SSS-grade equipment...]

From then on, Mike used the system to quickly level up in Miracle. Gradually, when he looked back, he had become the world’s greatest existence!

At the beginning, he said: “Little concubine from Jiangning County, what an insult to status, I won’t marry!”

After seeing it, he tsk-tsk: “It’s so weak, it’s too weak, I don’t want it!”

When she came to the door alone with a marriage certificate, he stood leaning against the door and smiled subduedly, “Come and let me marry you? But I don’t want to marry young!”

Knowing that she came to divorce the engagement, his complexion was completely dark, and he wanted to kill someone gloomyly, “Who gave you the courage to withdraw the young master’s engagement?”

…

Su Rong felt that Princess Duanhua might be blind. This person is so pampered, how could it be worth her to die and live for him?

If I had known, when she saw him for the first time, she threw the divorce letter in his face.
