I Am the Cannon God

The plot has fallen apart. The protagonist's cheat ability is too overpowered, and the author can't balance it, so he has to force it down. As a result, the protagonist's behavior and thoughts feel contradictory to the readers.

I suddenly discovered a way to exploit a bug. Don't road repair shops just put broken guns in for repairs, making them look brand new and giving them a full load of ammunition? Take them out, remove the ammunition and barrels, put them back in, and repeat this process. For a thousand guns, take out the firing pins, put them in, repair them, and when you take them out, you'll have a thousand full loads of ammunition!

800-1000 Dollars is a bit exaggerated. During World War II, the US military uniform and carrying equipment, excluding weapons and gear, cost around $80, which is about 190-200 dollars.

The book is titled "God of Artillery," yet you've never fired a cannon; all you know is how to use a small mountain gun! And why are you following the Kuomintang when you have nothing to lack?

You've never played Red Alert. With such a powerful cheat, you're still getting chased like a dog by some lowly player. Heavy artillery is positioned on the mountain, and defenses are set up around it; anyone who comes near is doomed.

Even if the War of Resistance against Japan hadn't lasted eight years without you, it would still have taken eight years even after you time-traveled. So you time-traveled for nothing!

Writing about the Battle of Nanjing is fine, and I like the premise. But since you're not letting the protagonist drastically alter history, their role is limited; they can't defend Nanjing or evacuate the civilians. So, quickly let the protagonist accumulate merit and rise through the ranks, then change the map.

Preparing to enter the palace—this speed is what the old eunuch of the Imperial Household Department wrote.

Basically, it's like conjuring weapons out of thin air. Anyone with a brain would be suspicious of such a conjuring. Weapons have serial numbers, which can be easily checked in the original weapon records. It's not just weapons produced a long time ago, like those manufactured before or during World War I, because war weapons often change hands multiple times. For other weapons, you can even trace which unit used them.

It's well-written; the only downside is that there are too few updates.
