The two people that came out of the cave were wearing olive-green uniforms, and they each carried a submachine gun. They seemed to be the Underground Ark's guards.
They looked around to make sure nobody else was around before carrying the heavy sack deeper into the valley.
Before long, they found a relatively soft spot and took out two shovels from the rucksack.
Jiang Baimian signaled to her team members and quietly led them down from their high ground to a spot not far from the two Underground Ark guards. She then suppressed her voice and said to Shang Jianyao, "Go."
Shang Jianyao did not decline the responsibility. He rushed out of his hiding spot with the Berserker assault rifle and shouted at the two Underground Ark guards, who were digging a hole. "You've been surrounded!"
