“The world underwent a mutation that year. The game world appeared in reality and various disasters started to ravage the world.

To resist all of this, everyone had to plan for their job choice, manically level up, and strive to become stronger.

There were mages, warriors, knights, and summoners—over 100 different kinds of jobs. This was a job that a person would be stuck with his entire life. Thus, everyone chose cautiously. Out of this dazzling array of jobs, Moses picked Knight—which had the most average ability value—to be his job.

At the same time, he also awakened the Hundredfold Increase System.

“”Ding! Detected that the host learned Shielding. The skill has become Absolute Defense after the hundredfold increase!””

“”Ding! Detected that the host learned Defensive Domain. The skill has become No Damage Domain after the hundredfold increase!””

At the same time, Moses also discovered that his job could evolve infinitely!

“”Ding! Detected that the host’s Knight job has met the conditions for a hundredfold increase. The job has become Great Knight… Paladin… Impregnable Fortress!”

See you for the first time.
In front of the teaching building, fourteen-year-old Xu Can was sitting in front of the steps crying uncontrollably, when a voice suddenly came from overhead and asked, “What’s the matter with you?”
She was so frightened that she raised her eyes, and was amazed again.
With tears in his eyes, he sniffed and held it for a few seconds, not wanting to tell the truth, “Teacher, I… I didn’t do well in the exam.”
Tong Mingyue sat next to her and chatted with her.
The next day, Tong Mingyue passed by the school’s display board.
I saw that Xu Can, who spent a long time in teaching her classmates who didn’t do well in the exam, ranked first in the overall ranking list, and almost got a perfect score in every subject.
“…”

After working hard all his life, he was still unable to cope with the drag of his background. Before Xu Can was forced to jump off the building, he regretted that he could not see Tong Mingyue again.
When I opened my eyes again, the computer was lit up with a blank document.
Back to sophomore year.
Failed subjects, no money, there are still two professional exams in sight…
In this life, Xu Can walks without heart and heart, with eyes full of eyes, only Tong Mingyue.
