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!”
