章 650: The 21st Checkpoint

After 6 p.m., Lin Huang had finally broken through the 20th checkpoint and arrived at the 21st checkpoint. He had primarily managed to break through each checkpoint within ten minutes for first to the ninth checkpoints. However, he and the Mighty Ape took more than 15 minutes to get through each checkpoint since the 10th one; some even took more than 20 minutes to break through, especially the 20th checkpoint that they had just passed. For that particular one, they needed half an hour to break through it.
