Unleashing Chaos Through Upgrades

Zhang Binn didn't understand what was happening. A group of young men was beating him. One of them, the most arrogant, stood on his chest, pressing so hard that he was about to lose consciousness.
"Ding dong: Unrivaled Berserk System activation successful!"
When he received several notifications, a strange and warm energy coursed through his body, bringing him back to consciousness.
After receiving some strange fragments of memory, he understood that he had transmigrated to the Vast Dragon Empire. He now occupied the place of a young cultivator who, due to some misunderstanding, was about to be killed.
However, to his fortune, he had awakened one of the most powerful systems.
Weapons, cultivation techniques, martial arts, and even effortlessly leveling up his cultivation were all possible with the Unrivaled Berserk System.
It all relied on experience points, and to gain experience points, he needed to control people's emotions.
"Killing intent detected +60!"
"Fear detected +40!"
He also earned points by killing his enemies.
But in addition to all the benefits, the system also demanded completing missions in exchange. If Zhang Binn failed to do so, the punishment would be severe.
"Ding dong! The system has issued a primary mission. In three months, become an Inner Sect disciple of the Heavenly Rotating Jade Sect. If you fail, your brother will shrink by five centimeters!"
