Save a Failed Idol's Life - Chapter 270:

Jinhyuk, a gaming Nutuber, was the only person who saw the ending of the game [Tower of Trials].

However, when the game’s popularity declined, it became difficult for him to continue making a living as a gaming Nutuber.

Since he already saw the ending of the game, he was about to quit playing. But that day, [Tower of Trials] became reality, and Jinhyuk, who knew about every single thing in the game, took over everything faster than anyone possibly could! “I’ll show you what a true pro is like.”

To corrupt the system!minute later....[System integration... 85%...][System integration... 99%...][Integration complete!] It ran one last time...“Did I succeed?”And so the journey started.

Lin Jiufeng transmigrates to become the Yuhua God Dynasty’s Crown Prince but is dethroned, banished to the Cold Palace, and imprisoned there because he had released the holy maiden of their rival country.

Lin Jiufeng isn’t dejected. He has brought a sign-in system with him when he transmigrated and he would receive rewards when he signs in at different places.

Before the Cold Palace’s gates, he signs in and receives the Ultimate Heaven Slashing Sword Skill!

In the Great Council Hall, he signs in and receives the Heaven Patching Technique!

In the Empress Dowager’s palace, he signs in and receives the God of War Totem!

…

Liu Jiufeng imagines that he can quietly sign in like this until he becomes invincible. Yet who would have imagined that the Heavenly Concubine whom he secretly released would rise in rebellion and seize power after she returns to her country?

After she succeeds, her first priority is to attack the Yuhua God Dynasty to rescue Lin Jiufeng.

When Liu Jiufeng hears of this news, he’s puzzled. «Do I need you to rescue me?»

Yin BiYue has made the worst purchase ever. After transmigrating countless times into the bodies of canon fodder villains, he buys a ‘Fiend Halo’ from the Rebirth Company, supposedly the best aid for an up and coming final BOSS!

He’s ecstatic to finally get a villainous role where he won’t die after just a few lines, if any at all, and is raring to become the best opponent a protagonist will have… However, why was everyone looking at him with pitying eyes? Why was the protagonist rushing over to help him get out of his crimes? Most importantly, why was his ‘Fiend Halo’ just making things worse?!

Meanwhile, the intern salesperson at the Rebirth Company discovers that he might have accidentally sold a prototype White Lotus Halo to a certain villain…
