At the moment when Lin Yan finished speaking, Meng Yao retorted: "But I still don't feel safe, how did you say that Teacher Wu knew this code? I guess someone else must have told Teacher Wu this code." Even if it's the dance teacher's own thoughts. Then how can you be sure that the dance teacher only told us.

Suppose he told someone else, and he told that person happened to be our enemy. If he kidnapped us and me, we'd still be in a bit of a danger, and if we carved a code, he would find out and we would run away. Then he will be more vigilant, and won't that be self-defeating?

Lin Yan nodded in agreement. But Wu Shan retorted: "Then what should I do? I can't be kidnapped anymore, I don't want to escape yet, just sit and wait for death." ”

Meng Yao smiled and said, "How is it possible? As long as we create a code by ourselves, won't the enemy find out?"

Wu Shan didn't speak, but Lin Yan asked curiously, "How to change it?"

Meng Yao replied: "We just need to modify it on the basis of the original, and the dance teacher said this, 'If there is danger in the future, if there are a few enemies, we will carve a few points.'" That way, you won't find out so easily. But remember that you must be subtle, otherwise this code will be useless. The enemy will still find out. Carving a dot only reduces the chance of the code being discovered by the enemy. It cannot be completely waived. ’”

Wu Shan nodded, but he was thinking in his heart: Why is Meng Yao so good?

When Lin Yan was about to ask, Meng Yao said again: "For example, change what the original dance teacher said, 'There are several enemies, and we are on wood or stone.'" Carved right, if there is an enemy, we will carve 1 stroke. If we have two enemies, we will draw 2 strokes, if there are three enemies, we will draw 3 strokes, and so on if there are 10 enemies, we will draw 10 strokes. ”

Listening to Meng Yao's words, Lin Yan and Wu Shan nodded thoughtfully. This Lin Yan asked again, "Then what?" After listening to Lin Yan's words.

Meng Yao continued: "After that, we will take what the original dance teacher said, 'If the enemy's soul ring is three rings, we will carve three marks on one point.'" Tick a little smaller. In this way, we will know the soul power of the enemy. Also, this code can't be known to too many people, only to those you can trust. Otherwise, the enemy will know. This code doesn't make sense,' said the dance teacher. ”

Wu Shan nodded again, and then said in a slightly impatient tone: "We all know this, so we don't need you to remind us." ”

Meng Yao glanced at Wu Shan. Again, he said, "We can openly use what the dance teacher said: 'If the enemy's soul ring is three rings, you can carve three marks on top of one point.'" Tick a little smaller. We know the enemy's soul power. Also, this code can't be known to too many people, only to those you can trust.

However, after we have engraved the code of the dance teacher, we should engrave such a code in a more hidden place: if the enemy is the five rings, we will hit five points. In this way, if the enemy finds out, they will think that we are talking to us with the dance teacher. There are a few enemies who carve a few dots on that code, so that we can mislead the enemy into thinking that we don't know their true number. So that the enemy relaxes his vigilance. ”
