The Dinosaur Army were born warriors; after gathering on the Heavenly River side, they didn't take any rest and charged forward with invincible momentum.
Due to the sudden attack, the alliance was unprepared and unable to offer effective resistance.
Thus, after just a few exchanges, the alliance army had already suffered a disastrous defeat, with significant casualties.
Seeing the Heavenly River defense line on the verge of collapse, peak warriors like Chu Tian, Bai Huaxiang, Xie Chen, and Wan Jianyi stepped in to assist, finally stabilizing the formation.
Not until the night fully descended, with blood staining the Heavenly River and corpses blocking the flow, did both sides sound the retreat and return to their camps.
The first day's battle saw victories and losses on both sides.
However, in terms of casualties, the alliance suffered more severely.
