After Du Wu and the Divine Beast Yemen had a direct conversation at the soul level, she called this communication soul docking.

Using Yuanying to directly enter the other party's brain, you can not only perceive the other party's thoughts, but also pass on your own thoughts to the other party, saving the trouble of intermediate language.

However, this approach has certain limitations. First of all, one party must have cultivated the condensation of the Yuan Infant like Du Wu, and the other party needs to fully cooperate and unconditionally obey and trust the dominant party.

Otherwise, it will cause great damage to the souls of both parties. Therefore, it is not casual to use. It's good to use it for eagle training now.

After Du Wu cut off the soul docking with the divine beast Yemen, Yuan Ying left Yemen's brain. She came to the side of the black feather eagle and stroked the feathers of the black dot with her hand, signaling the black dot to relax.

Because Wu Dian knew that it was Du Wu who saved its life and could give it delicious jerky, he trusted Du Wu very much, and under Du Wu's touch, his whole body relaxed, and a pair of eagle eyes closed comfortably.

Du Wu took the opportunity to use Yuan Ying to enter the head of the black dot, and the yuan baby gently wrapped the brain of the black dot.

At this time, Du Wu found that the brain of the black dot was very small, only as big as a walnut, and it contained very little information, so it was very easy for Du Wu to find its language center.

Du Wu manipulated Yuan Ying to perceive the information in the Wudian Language Center, and found that it was extremely simple, and when translated into human words, there were only a dozen sentences in total.

It turned out that eagles were sending food and danger messages to each other. For example, where there is food, where there is danger, in what direction, far and near, etc., as well as a few words indicating the water source and habitat, Du Wu took two cups of tea to write them all down.

Then she began to try to talk to Wudian, and after a day, she was able to communicate with Wudian in Eagle language simply.

Eagle language is extremely simple, just a combination of the number of chirps, the length and the level of the voice, and it becomes these dozen sentences.

The number of times the black dot chirps is only one, two and three, and with the length and level of the volume, it can express some simple meanings.

They do not have the same complex language as human beings, and other complex feelings cannot be expressed through language, perhaps this is why human beings are the first of all things in the world.

Du Wu tried to teach Wudian to deliver letters, which was relatively simple. She asked Wudian to remember the appearance of Ruyi and the others, in fact, Wudian had already recognized the appearance of the five people clearly, and it naturally had its own methods.

Du Wu asked Ruyi and the others to go to the southeast, northwest, and northwest directions, and walked one or two miles away. Then tell the location of the black point, and the black point can accurately hand over a small item given to it by Du Wu to the person in that direction.

It is believed that if it is trained and the distance it can send messages is slowly extended, the black dots can be used as their messengers in the future.

In addition, one of the biggest functions of Wudian is reconnaissance. Du Wu took out the map of the treasure of the martial god to Wudian to see, one of the maps had two small characters, written in the Northern Desert, Du Wu took this map to Wudian, and did not expect Wudian to know this place.

According to its eagle language, it is probably that this place is far to the north, and it used to fly there.

Du Wu couldn't help but be overjoyed, the Flying Dragon Continent also happened to be in the north, so directly to the north, the two things could be combined together.

So she let Dots lead the way, heading towards the place on the map. Wu nodded and flew up in the air, heading towards the north, it didn't fly high, and it kept hovering in the air about a hundred zhang, so that Du Wu and the others could keep up with its speed.

Sometimes he would fly back and ask Du Wu for some dried meat to eat. In the next few days, Du Wu taught the Eagle Language to Ruyi and the other four people, and everyone learned the language of Wudian, and there was no need for Du Wu to always dispatch Yuanying.
