Wang Heng'er had already seen this trick of spitting green fire from their mouths, what should he do? He could only raise the Inner Yin Skill to the highest level and use the fire dragon to fight against it. At that moment, there was a fire dragon illusion in Heng'er's lower dantian, and in an emergency, the fire dragon unconsciously flew out of his lower dantian and hung in the air, just like when he passed the chain bridge when he arrived at Yaowang Peak, the fire dragon broke away from his body, but the fire dragon gently and skillfully blocked the green fire.

When the head of the crocodile elephant saw that the green fire could not hurt Heng'er, he led the green fire towards the platypus, and the platypus screamed in horror when he saw the green fire.

"No! If the green fire burns at the platypus, the platypus will be burned to death, and their hard-won fighting spirit will be lost, and the next thing will be defeated. ”

Wang Heng'er wanted to use his mind to lead the fire dragon to the platypus and help them disperse or block the green flames. At this moment, a feeling that he had never felt before surged in his body, and many powerful Yuan forces turned into many warm currents, flowing from his limbs to all directions of his body, and finally converged along the meridians to his lower dantian, which was like lighting a fire in an instant, burning brightly. Wang Heng'er was stunned: "What's going on? Could it be that this is the phenomenon of thousand-year-old ginseng being refined in the body?"

He intended to lead the fire dragon to the platypus's idea, but accidentally ignited the fire in his lower dantian, and then the fire burning in the lower dantian came out, and quickly fused with the fire dragon, under the golden light in the sky, the fire dragon quickly transformed into a blue cloud, at this time, Heng'er's body rushed out of the powerful Yuan force wave, this Yuan force wave shrouded around the blue cloud, only to see the blue cloud expand rapidly to all sides, gradually changing a wide blue disk, and there are obvious water-color ripples on it, as if a lake suspended in the air, this lake quickly shrouded the green fire of the crocodile elephant beast firmly under it。

Heng'er was amazed to see this scene, and he knew very well that this was what people called the essence of the Yin realm.

"Jing Yin Realm!" he couldn't help but exclaim.

With the help of the thousand-year-old ginseng, at this tense and critical moment, his inner yin gong successfully broke through the dantian weight of the inner yin gong and ascended straight to the essence yin realm of the realm realm, which is a qualitative breakthrough, and its speed is really incredible.

People are often under the most nervous conditions, they can give full play to their greatest potential, and this greatest potential is combined with the energy emitted by the thousand-year-old ginseng to produce the greatest yuan force, and complete the breakthrough and upgrading of the inner yin gong. This also verifies what the Bian Medicine King said that the thousand-year-old ginseng can help the internal yin gong upgrade, but Heng'er never expected the upgrade to come so timely and so quickly.

Heng'er was overjoyed to see that his inner yin skill had been upgraded, he swung the Taiyu sword out, pointing directly at the lake suspended in the air, the sword peak emitted a golden light, flashing into the air lake, he swung the sword downward, the lake suspended in the air, the rain of light pouring down, slammed out the green flame, and the platypus was saved.

When the leader of the crocodile elephant saw this trick, he could not win, and thought that the platypus had the help of the gods and men, so he had to retreat on all fronts.

Wang Heng'er wanted to take advantage of this to kill again, but he saw that the platypus did not have this desire and intention, so he had to give up such thoughts, and the security was appropriate, so he gradually accepted the inner yin gong, and at this time, he saw that the hanging lake gradually shrank, and finally turned into a point, flashed into Heng'er's body, and then put the Taiyu sword into the Qiankun bag.

When the platypus saw that Wang Heng'er led them to work together to kill the crocodile elephant beast and avoid an extinction disaster, they were very grateful to him and took the initiative to favor him. They were shouting, singing, and dancing around Heng'er, and some were playing with their heads on top of him. After this battle and the observation during this time, Heng'er at this time is not as afraid of this behemoth as when he first came to see the platypus king, he understands the kindness of the platypus very well, and also rejoices with them to celebrate the victory, it seems that this platypus is a good beast with human nature.

At this moment, the platypus king was lying on the ground, not having any fun with them. Heng'er thought that this platypus king must have an injury on his foot to cause this. Heng'er approached the platypus king, he wanted to see the injury of its foot, in fact, the platypus king's foot injury was not very serious, the piece of flesh on its foot that it was bitten off by the mountain turtle looked like a big piece for humans, it was only a small piece for it, and the wound had formed a flame, for this huge platypus, this was just a small injury, it should be fine.

Heng'er thought that the platypus king might be hungry, so he came to the crocodile elephant beasts that were killed, he took out the Taiyu sword from the Qiankun bag, cut off a piece of meat from the crocodile elephant beast, and threw it to the platypus beast king, signaling him to eat it, but he didn't expect the platypus beast king to be frightened by his action, he got up from the ground, and made a "whoosh" sound, Heng'er didn't understand: "What's going on? He cut the flesh of the crocodile into small pieces and scattered them among the platypus, and the duckbills looked at it one by one, but none of them thought of it as food. At this moment, he saw the platypus king eating some aquatic plants by the lake. Only then did Wang Heng'er realize that although the platypus was huge, they were still a herbivore, gentle and timid by nature.

At this time, Heng'er consumed a lot after fighting with the crocodile elephant beast, and he was so hungry that he couldn't care about the raw and cooked meat of the crocodile elephant beast, so he ate it in a big gulp. All the platypuses saw him and walked away.

Heng'er now knows some of the platypus's nature, and he walks up to the platypus king and wants to communicate with it, but he doesn't know the beast's language, so he can only interact with them with his body to express his meaning and guess their intentions.

The platypus has a certain spirituality, when he walked to the platypus king, the platypus king nodded to him, and motioned to let him eat the aquatic plants, Heng'er smiled at it, picked up a handful of aquatic plants, washed them in the lake water, and put them in his mouth to chew, this aquatic plants taste really good, there is a faint sweet taste, Heng'er is thinking, if you can't get out of this other world for a while, you can only feed on this aquatic plants.

Heng'er thought of the previous platypus king, who had just come here from the mountain on the left alone, and he wanted to know the reason, so he made a gesture with his hand to see how the platypus king reacted. He did it several times in a row, and at the same time said and screamed, the platypus king seemed to understand some of Heng'er's meaning, it didn't show any body movements, Heng'er felt very strange, but Heng'er seemed to see it crying, he didn't believe his eyes, could it be that the platypus encountered something sad, and also had the same meaning as humans?

Heng'er was indeed right, only to see a large drop of eye water flowing out of the platypus beast king's eyes. It seems that this platypus king has indeed encountered something sad on the side of the mountain on the left.

After a long time, the platypus beast king stopped crying, somehow, after looking at Wang Heng'er for a while, it lowered its head and kept screaming, what does this mean, Heng'er made all kinds of guesses, but none of them. He lowered his head and cried out, not to tell him to climb up, and so he climbed on its head, and it raised its head high, and no longer crowed, and strode forward, and the other platypus, all in a cheerful manner, followed it.
