How to play this round?

Changsha ship confronted foreign ships for 47 hours. Changsha ship defeated the enemy without fighting and blocked the foreign ships without any effort. How domineering it is.

At that time, the main gun and secondary gun were ready for the first level of battle.

If Changsha ship and foreign ships go to war, the main gun will attack and the secondary gun will intercept, sinking the foreign ships one by one.

This is a strong performance of the country.
