Jaku-chara Tomozaki-kun - Volume 2 Chapter 3 part1-2

Ajax was an orphan who survives a massacre along with his friends but unfortunately gets separated from them.

Fortunately, after a turn of events, he successfully gains a system which helps him increase his cultivation, but doesn't know what it is called.

But he knows one thing for sure, this system is very powerful and helpful in taking his revenge.

“Whoever you are, I am gonna find you”, Ajax mumbled himself with a disgruntled expression.

In a world where Summoning of an elemental spirit is done through a dream when they are 15 years old, Ajax with the help of a system and his summoned spirits sets out on a journey to seek revenge against the mastermind behind the massacre.

A master assassin transmigrates into an interstellar era.

By some ill fortune, Hikaru died in a traffic accident. He was in heaven standing in line, waiting to be judged, when he took an unexpected request to transfer his soul to a person in another world. He received an ability called Soul Board which he could use to allocate points to Skills to make himself more powerful.

But there was a catch…

「I want you to take revenge on someone for me within an hour. If you don’t, I’ll destroy your soul.」

To pull off the task assigned to him, he poured all his available points to the Stealth skill tree.

This is a story of a boy who specialized in Stealth. With his skill trees as weapons, he would demonstrate his unrivaled strength in another world.

Su Shi was once a platinum-level host with the highest survival rate. One day, his misdeeds of constantly shifting his blame onto others was found out and reported. Convicted of violating the rules, he was bound to an Automatic Blame Shouldering System and exiled to lower-level worlds.

Now, not only does he have to take the blame from others and shoulder it himself, he must also carry that blame and rush to his death in order to earn enough points to quickly unbind from the system.

Su Shi only wants to get rid of the system by shouldering the blame until death. However, he finds that trying to hold onto the blame is even harder than passing it on, and rushing to his death is even harder than running for his life.

As Su Shi lies dying in the protagonist’s arms with red-rimmed eyes and a weak and helpless countenance, an uninvited third guest suddenly rushes out to explain the misunderstanding for him.

Su Shi: “I beg you, just let me shoulder this blame, otherwise, it will all be a waste of effort…”
