Gu Lan quickly arrived in front of the iron ring stone wall.
The stone wall was covered with palm-sized iron rings, each only as thick as an index finger, and the parts used for wall connection could sway up and down.
Grabbing the first one, Gu Lan determined the load-bearing capacity of the iron ring. These rings could naturally be used for climbing, but stepping on them would cause them to bend.
So, this wall required precise control of foot force and arm strength, further testing the soldiers' balance abilities.
She looked up and saw that there were five more such short walls ahead, evidently a test of endurance.
Chen Da had already taken the lead and climbed up.
His tall and robust build made climbing this wall particularly strenuous, and as soon as he was on, he missed his footing and fell.
Luckily, Chen Da was experienced in this, and when he fell, he adjusted his position and landed on his backside without injury.
