He looked at the blueprint in front of him, revealing a satisfied smile.
The blueprint showed the upgraded Mechanical City, entirely cast from solid alloys, with a significantly enlarged area compared to before.
The newly designed Mechanical City is large enough to accommodate millions, or even hundreds of millions of people, and it can continue to expand.
It's not just the size that has increased.
From the blueprint, you can see that Su Yu designed many heavy war machines, placed throughout the city, leaving no blind spots.
Just by looking at the ferocious designs, you can tell these weapons are extremely terrifying.
Any enemy daring to invade would immediately be bombarded by these horrifying weapons.
Even a seven-star or eight-star enemy might not withstand it.
Because Su Yu took the heavy weaponry from the Assault Tank and magnified them ten times as the city's defensive firepower.
