Sky Moon gazed over and his heart sank immediately.
He turned toward Lu Li and looked at him helplessly, and began to doubt whether the city wall could stand the attack of these new cannonballs. After all, since Glory Capital only had a dozen or so chariots left, their apparent self-confidence probably came from the advantage of these new weapons.

The overwhelming advantage would be with the defenders. They had reinforced their sentry towers and limited their chariot numbers. On top of that, the attackers were using a 40+40 formation, which, in addition to the extra shield the wall gave the defenders, made it very hard to capture the Stronghold, unless they used some special method.
Apart from Sorrowless' last resort trumping the strength of Ruling Sword's members, those cannonballs were also terrifying.
