MTL - Card - Chapter 90 by millimeters

Rimu Dynasty, Kingdom of chaos. Demons were rampant, and it was difficult for people to live.

Gu Qing’an had not yet had the opportunity to appreciate his beauty upon transmigrating in this world, as he had to face the demon who targeted and devoured humans.

Fortunately, she had a system.

“I, Gu Qingan, have never been weaker than others. System, add it to me.”

……

Many years later, Gu Qing’an, standing on the frozen void, looked at the newly discovered strange world under her feet without any expression.

“Compared to human beings, alien existence is a demon,” she thought to herself.

“Then, are all creatures in this entire world considered demons?”

PS. Cover not mine, I just found it on google.

In a dilapidated temple, a young man receives an outdoor webcast system, and thus, his webcast journey begins. He easily finds lingzhi worth thousands of dollars, keeps a falcon as his pet, and displays skills that leave his audience in awe. When he turns his head around, he discovers that the whole world is watching him.

When he joins a show, everyone asks, “Is this webcaster cultivating to be a deity?”

Someone exclaims, “This isn’t an adventure, this is a vacation!”

A reporter asks him, “Your fans claim that you know martial arts. Is that true?”

He answers, “Not true.”

Yet, in the next moment, when a little red bird flies past him, he takes a leap from a tall platform before jumping down…

He had never invested in shares or bought a lottery ticket, and neither did he have any experience in the general business industry. Lu Li found that the only thing he could do was play games.

Luckily he had experienced rebirth, and was one step ahead of everyone else. Luckily, games had been developing extremely quickly, and there were many people who had become rich through playing games.

In his ‘past life’, he had spent countless nights awake, in grief and anguish. However, although all of this had been washed away, so what…? This life, he was determined to make a fierce counterattack against fate and stand at the very top!
