Deep in the Mengzhong Desert, Helian Eagle and Yunzhu guard the oasis and ancient secrets left by their ancestors.
The "Iron Blood Alliance" of a large guild broke in, and the leader massacred Baicheng to seize the treasure but failed, so he kidnapped Yunzhu.
The Helian Eagle activated the "quicksand labyrinth" that had been dusted for thousands of years and swallowed dozens of intruders in an instant.
Tu Baicheng used gunpowder to blast open the "water eye" of the oasis, and the water source of the oasis was on the verge of drying up.
The elders of the survivors sacrificed their lives to restart the ancient mechanism, the oasis returned to life, and the truth about the secret treasure was revealed before his death:
"The so-called skill book is actually an ancient ecological code that maintains the balance of the desert..."
During the decisive battle, Tu Baicheng fell into the quicksand, but grabbed Yunzhu's ankle at the last moment.
The yellow sand is rolling, and Helian Ying's arrow has been aimed at Tu Baicheng's eyebrows.
