At the end of a Dynasty filled with Demons and rampant Martial Artists, Lin Xuankong has unfortunately transmigrated to this era, becoming a poor and sickly old man. However, with the help of the system Life Plate, his Talent and Comprehension grow stronger the longer he lives.And his much younger wife is a martial master...“That iron ball used to be Zhang Wu's knife. I squeezed it a couple of times, and it ended up like this! ” said his wife.“I hope you can teach me some Cultivation Techniques. As for the reward...” said Lin eagerly.

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.

- Description from novelbuddy

Arthur was a weak and cowardly boy who lacked the power to protect anyone—a truth brutally demonstrated when his parents were massacred while defending him during a Gate outbreak. As the sole survivor, Arthur spent weeks believing his life was over. When intense chest pains began, he assumed he'd been infected with corruption by the void creature that killed his parents and was merely waiting for death.What Arthur didn't expect was that these sensations actually signaled his Realm Core forming. In two months' time, he would be forcefully transported to the next realm and awaken new powers, becoming one of the world-renowned “Chosen” who protect humanity from Gate outbreaks. Now Arthur must rise through the heights of power, climbing each of the seven realms in hopes of saving his world... or does he?
