MTL - The Public Enemy of Tower Defense - Chapter 21 who is the traitor

One morning, after being bound to the system, MC started his routine of always being captured/ attacked by the ML.

The Master of the Tai Yi Sect, Patriarch Xu Yi shattered the void, causing the entire sect to travel through to the interstellar era.

On the deserted planet, the disciples discover a new world:

The eldest senior brother, who specialized in forging, fell in love with mech building. The second senior brother found that alchemy could also be manufactured on an assembly line; The third senior brother fell in love with live broadcasting and was addicted to the Internet; The old Master Xu Yi cracked his whip and urged the disciples, ‘This world is so rich in spiritual energy, how dare you not cultivate properly?’

In the Immortal Cultivation Realm, Junior Sister Sa Sa, who had no spiritual root and powerful spiritual sea, was finally no longer distressed by her inability to cultivate: ‘Mech’s are really powerful!’
Double standard — Xu Yi: … Study it. Isn’t it just mechs, Sa Sa should have one too.

A little bumpkin from a deserted star came to the Federation’s First Academy.

Sa Sa, ‘Wow, the internet is awesome! Mech’s are awesome! Technology is awesome!’
‘You don’t need to cultivate to become strong in the interstellar world, I really love love love it.’

Students from prominent and powerful backgrounds scoffed, ‘Where did the bumpkin come from? Is there something wrong with the admissions system?’
They had no idea that the anchor who exploded onto the internet had a great relationship with the little bumpkin.

Sa Sa: ‘Third Senior Brother is secretly on the internet again!’

The elixir that the little bumpkin usually took and hard to find, the spirit sea boosting pills with no side effects, was actually worth a thousand bucks?

Sa Sa, ‘Second Senior Brother makes the most delicious sweet pills!’

The mech that the little bumpkin casually pulled out was actually the upgraded version of the mech that everyone was fighting over?!

Sa Sa, ‘Eldest Senior Brother will definitely save the best for me!’

The whole planet was abuzz: ‘What kind of divine institution was Tai Yi? How do I get in? Waiting online for a reply!’

He was persuaded into playing the VRMMO 「Trailblazer」 or TB for short by his cheerful childhood friend Miyu.

But Wataru faced Miyu, who was full of motivation and said this.

「Then, I’ll be the rearguard. Shinto priest? I’ll take this one」

「What!? You are not going to fight next to me!? And you call yourself a man!?」

For some time she would become one of the top players and start getting called Hero.

So Wataru had to deal with being an extra.

But, during a certain PvP event, a strange nickname was attached to Wataru.

That, he was actually the 「Hero’s true self」.

His friend and his wife betrayed him. The only thing left to him was his massive debt and his precious daughter. He was without hope as he lived at the bottom. However, a last chance had come to Sungyoon. He was a ‘man without a heartbeat’, and he will explore the Moon’s Labyrinth. He’ll explore the parts of the dungeon yet to be seen!
