A Valentine's Day Gift: A Mach Loop for the School Beauty?

On Valentine's Day, Su Yun, who has unexpectedly transmigrated, finds himself a delinquent student who never studies!

And yet the school's top beauty in the research program is head over heels for this delinquent!

It all happened so suddenly that he didn't have a gift ready.

Huh?

A handcrafting System?

Su Yun: "Wanwan, happy Valentine's Day. Here's the gift I made for you."

Lin Wanwan: "I'll admit, at first I didn't expect Su Yun to give me anything. Then, right in front of me, he made... made a..."

The military: "We heard there's someone here who has mastered the Mach 8 ring technology?"

The principal and department head: "Huh? You haven't?"

After acquiring the handcrafting System, Su Yun keeps going further down the road of making crazy stuff.

He thought the Mach 8 ring was the limit of what he could do.

But then...

An AK-47? Sure, I'll make one!

A bomber drone? Now that's cool!

A submarine? Damn, that's awesome!

A nuclear missile...

In the end...

"Su Yun, stop making stuff! You're scaring me!"

"No! Let him make it. Su Yun, the defense of our country is in your hands!"
