Yang Tian looked at the fist sized colored animal core in his hand and was surprised to find that its surface was actually covered with a very thin transparent film, which was scraped off with his fingernail, and the energy was emitted from the gap of the film.

Yang Tian finally understood why he couldn\'t feel the animal nucleus under the bone layer. Only monsters like little green dragon and little green turtle can smell the smell of animal nuclei.

Beiya didn\'t have this ability, so it was doomed to be futile. It dug three big pits up to five meters deep, and didn\'t find a beast core until it reached the rock under the bone layer.

The little green dragon and the little green turtle, like in a competition, get into the bone pile and take out a beast core every few minutes.

After working for half an hour, Beiya angrily threw his tools away. He finally understood that the animal core under the bone layer could not be dug casually by luck.

"Pa!"

The shovel thrown from the North cliff was inserted into the bone layer not far away and made a crisp sound. Suddenly, a powerful wave of energy came from the shovel.

The three turned around at the same time and looked there. Under the bone layer, the energy fluctuation was becoming stronger and stronger.

"Hahaha..."

After Beiya was stunned, he suddenly laughed and ran towards the shovel.

Obviously, most of the shovel he threw at random came into contact with an animal core, and a natural film on the surface of the animal core was wiped off.

But it was too early for Beiya to be happy. Before he arrived, he heard a "crash". The little green turtle suddenly came out from under the bone layer and almost hit Beiya.

The little green turtle, which came out from under the bone layer, had a blue crystal the size of a football in his mouth.

"This is mine, this is mine..."

Seeing this, Beiya came forward to hold the blue crystal in Xiaoqing turtle\'s mouth and shouted sadly.

The little green turtle shook his head and bumped the guy aside.

Immediately, the little green turtle raised his head and swallowed the blue crystal into his stomach. Then, he took a big breath of Hui echan and sucked Hui echan into its belly space.

After finishing all this at a very fast speed, the little green turtle retracted his limbs and head into the thick green turtle shell.

A moment later, the energy fluctuated from strong to weak, emanating from the body of the little green turtle.

"This is what I found now. You robbed my beast core..."

Beiya finally found a valuable animal core and was robbed by Xiaoqing turtle. He was very angry. At this time, he jumped to Xiaoqing turtle\'s back and stamped Xiaoqing turtle\'s back with his feet to let Xiaoqing turtle return the animal core to himself.

"Don\'t move!" Yang Tian said in a voice: "that blue crystal should not be a simple animal core."

Beiya jumped down from the back of a small green turtle and sighed helplessly.

Yang Tian smiled and threw the colored animal core found by a small green dragon to Beiya. "Here you are. Make it up to you."

Beiya took over the animal core, hehe smiled and said, "just now, I was joking. This place is too depressed."

Yang Tian nodded and looked around. Just now, he searched with his spiritual strength, but he didn\'t find the entrance.

It seems that this is a place with no access.

However, the strange program noticed that there was a slight fluctuation of Rune energy in the cave, which was collecting and calculating.

Although he didn\'t find the entrance and exit, Yang Tian was always vigilant to prevent black deer from breaking into here suddenly.

The black deer has been chasing, which has long been confirmed by the strange program. Yang Tian can clearly feel the fluctuation of Rune energy when the black deer broke into the array.

Obviously, the little green turtle has entered a state of cultivation, and more and more strong energy fluctuations are emitted from his body.

More than ten minutes later, the little green turtle\'s shell lit up, emitting a faint cyan halo.

Beiya kept taking out the fist sized animal core given to him by Yang Tian and putting it into the storage ring. He was very excited. He was poor and afraid.

Since I left Yuandao, I have never got such a high-level animal core. The owner of this animal core is at least an expert at the same level as Wulu. If the energy of this beast core is absorbed, the realm will be greatly improved

Seeing the excited look of Beiya, Yang Tian smiled and said, "now you have time, teach me the common language in the Xinghai!"

Beiya nodded and collected the beast in his hand.

Simple language learning is very simple for Yang Tian. He just needs to remember grammar and pronunciation.

Beiya started teaching from the common language. Yang Tian said it again and basically remembered it. Even if you can\'t remember, there is a strange program to help. It records all the process of Professor Beiya and analyzes and calculates the language

Xiaoqinglong was not idle. He kept walking under the bone layer. After a few hours, he stopped.

The animal nucleus under the bone layer is basically gone.

Before, the little green turtle turned out five, plus blue crystals, a total of six animal nuclei. The number of animal nuclei obtained by Xiaoqinglong is 73.

These animal nuclei vary in size. They are as small as thumb fingers and as big as Yang Tian\'s fist.

The blue crystal that little green turtle got was probably the most valuable, so he stopped looking and immediately began to attract crystal energy.

In a few hours, Yang Tian basically learned the common language of the world. When Yang Tian tried to communicate with Beiya in the newly learned language, Xiaoqing turtle changed again.

It was a turtle shell with a cyan halo. The halo suddenly converged, and its head, tail and limbs slowly stretched out. Then he opened his mouth and released Hui echan.

Hui echan was sitting cross legged, her eyes closed, and her body exuded the same cyan halo as the previous turtle shell, which seemed very holy.

After looking at Hui echan, Yang Tian suddenly found that Hui echan\'s temperament has become more mature, as if he had grown up five or six years old all at once.

"Boom ~"

Suddenly, a loud noise shook the whole cave.

Then, a figure fell from the sky and fell on the bone layer in front of Yang Tian.

The black deer finally appeared in front of Yang Tian.

At this time, Hui echan also opened her eyes.

In the moment of opening her eyes, Hui echan sent out powerful energy fluctuations, which surprised the sudden black deer and unconsciously stepped back.

The intensity of this energy fluctuation surprised Yang Tian, because Hui echan\'s energy actually caught up with him.

This entry speed is really... Crazy.

The opponent in Wu Lu\'s eyes was mainly Yang Tian. Although he didn\'t understand why Hui echan suddenly became strong, he quickly turned his eyes to Yang Tian and said faintly, "you can\'t run away. I\'ll take you away from Moyi cave and send you to the altar!"

Yang Tian shook his head, smiled and said in a strange language: "you can\'t go back. Don\'t you know that Moyi cave is a place where there is no return?"
