I Am Emperor Shenhao

Since the protagonist can shrink ten thousand times, there's no reason why he can't recover. If the protagonist can change size at will in another world, then why not build an army with so many things? Just like Gulliver, smash all the walls and fortresses on the opposite side, crushing all the enemy troops.

The author has greatly strengthened the description of Chen Ze. After entering the palace, you can't always wear the uniform when you change clothes. When you go to bed and go to court for review, you can also describe the layout of the dragon chair in the study hall ~ not only the extravagant description method of eating grapes when you first enter the palace, but also the carving of dragons and paintings of phoenixes.

Get some firecrackers to blow them up, many modern things can be used

Make a protective suit, then make it bigger, step on it a few times, roll around, tens of thousands of people can't bear it.
