Bing gives some more tips to Caitian, and Caitian can understand them immediately. He says that the old things like mechanical armor are obsolete, and that the more they are used, the worse their future will become. Caitian tells him that the enemy has set up traps all over the place, and he and Bing manage to avoid them. The two of them are calm, but the chaos of the situation reminds them of their old days. The enemy is well-prepared with traps, and the trap technique of the southern military is a joke, says Caitian. He tells the young man that if he can pass through the white spot in the forest in 8 seconds, the bronze eyes of the enemy will not be able to see him. This means that he can attack freely, even if he is in a blind spot. He also tells Caitian that he has not received any training on the short-distance sprint technique, which is the most important part of the battlefield.
