When the cannonball touched the Main Temple's Defensive Formation, a strange event occurred.
The cannonball suddenly split; the outer layer consisted of the immensely powerful Purple Cloud Thunder, which instantly unleashed formidable power, trying to blast open the solid barrier. The inner layer, however, contained Armor-Piercing Gold Essence specifically designed to break protective Gang Qi, like sharp daggers directly penetrating the enemy's vital points.
It can be said that these eighteen cannons represent the highest level of fusion between firearms and Dao Skill in the current era.
They embody the wisdom and hard work of countless craftsmen and cultivators, a perfect integration of the Great Yu Dynasty's technology and cultivation power.
