Until he became the lowest-ranked master, his lonely and luckless life never changed.Suddenly one day, a descendant injected him with a nanomachine, and the machine started ‘speaking’ to him.[I am the seventh generation Nanomachine manufactured by Sky Cooperation, and I am operating as a central nerve connected to your brain.]“What? What are you talking about?”This was beyond the boy’s knowledge, he turned pale.The Nanomachine linked to his cerebrum realized the User was not understanding a single word it said.“Who are you, and why are you doing this to me?”[“I am the seventh generation Nanomachine.]“Nano Machine?”[Yes, Nanomachine.]The boy’s face hardened.Mashin was the deity the Mashin Religion worshipped, along with the Sacred Fire.The religions’ Master communicated with Mashin.“Um, are you really Mashin?”The boy knelt down and asked with a trembling voice.

Our straight (?) bottom woke up ten years into the future and found himself on the bed of his childhood friend… At the start, the bottom was shocked to his very bones, but he soon quickly accepted this premise and found the whole situation to be rather amusing.

Su Yun crossed over and became a small anchor, suffering from lack of talent, he broadcasted live broadcasts of “hard training all kinds of unique skills” every day, wanting to make a living.

Such as: flying cards to cut flies; wooden swords to play table tennis; flying needles to shoot bulletproof glass;

On the first day of dawdling, Su Yun learned how to fly cards, and everyone thought he was here to make a joke.

On the fifth day, Su Yunfei split the cucumber, and everyone thought he had stopped here.

On the 30th day, Su Yun’s card cut through the stake ten meters away and killed the fly… After everyone was astonished, they all agreed that this was a special effect!

…

Until this day, Su Yun accidentally ran into a robber when he went out. He used cards to kill people, and the whole Internet was buzzing!

After a period of time, when Su Yun was accidentally exposed and received a summons from the police station to file a record, more of his skills were exposed one by one:

The light work of crossing the river with one reed!

The swordsmanship of splitting stones with one sword!

A flying needle comparable to bullet penetration…

Police: “Are you sure this is just an anchor? File it as an S-level file immediately!”
