No System. The year 2300.
The gods of every country in the world have revived, and after awakening, they take control of their respective nations. The world's existing balance of power changes in an instant. Countries with gods begin waging war, while those without them are destroyed. Gradually, people discover that China has no gods.
Countries everywhere come to harass China, which vows to resist to the death. Everyone who feels a deep bond with their country heads to the front lines of their own accord: veterans, people from every province.
All of China stands united. The battle begins, and Chinese soldiers would rather die than retreat a single step. They endure dozens of casualties just to take down one believer, and still refuse to back down.
They grit their teeth and bear the pain, all for the sake of defeating the invaders. China has thousands of years of history behind it. We have never relied on gods; we have always relied on ourselves. If anyone invades us, we will fight back with all our might.
Just as China is on the verge of defeat, a voice rings out.
“Who dares bully the descendants of Great Qin? Great Qin's elite soldiers, charge!”
It's very good, but the author may not be familiar with the battle scenes.
Very well written, good luck to the author
