Invincible Instant Upgrade System

"Huh? Where is this? Why am I here?" The young man rubbed his eyes, opened his eyes in confusion, and looked around, full of doubts in his heart. He shook his head vigorously, trying to wake himself up, but suddenly he felt a severe headache, as if it was going to explode. The memory in his mind became blurry, and he couldn't remember what happened before. He only remembered that he was busy in the company, leaving early and returning late every day. The long hours of work made him exhausted. That night, he was so tired that he decided to order a cup of coffee to refresh himself. However, when he stood up, he accidentally knocked his coffee over the power strip, and then his vision went dark and he lost consciousness. "Am I already dead?" The young man couldn't help but feel fear. "Is this hell or heaven? I'm still young, and I still have a lot of time and wealth waiting for me to enjoy!" He tried hard to recall more details, but the pain was unbearable as if his head had been hit by a heavy object. Doing nothing would bring about bone-chilling pain, making him moan uncontrollably.
