Hearing that the Tianyuan Demon Lord mentioned the treasure that shielded the power of the Heavenly Pluto Star as soon as he opened his mouth, although Yin Gengyu felt a little depressed and even helpless in his heart, this time, he was extremely refreshed, and directly agreed to hand over the secret method of refining the treasure that shielded the power of the Heavenly Pluto Star Heaven and Earth, but the premise was that the Tianyuan Demon Lord must arrange for him to meet with the Red Sky Demon Lord in a short period of time.

Yin Gengyu did this because he knew that the Tianyuan Demon Lord was too cunning, and he was worried that after the Tianyuan Demon Lord obtained the secret method of refining treasures, he would not teach this secret method to the Red Sky Demon Lord, but would enjoy it for himself, and then try to refine the treasure with strong shielding ability, so that after his strength became really strong in the future, he would return to the Heavenly Pluto.

In this way, his hope of using the hand of the demon to get rid of Long Fei in a short period of time, and then continue to carry out the plan, will be frustrated.

Therefore, while agreeing to teach the Tianyuan Demon Lord the secret method of refining the treasure that shields the power of the Heavenly Pluto Star, Yin Gengyu asked the Tianyuan Demon Lord to arrange for him to meet with the Red Sky Demon Lord.

"Do you mean that after you meet the Red Sky Demon Lord, you will teach us the secret method of refining treasures?" The Tianyuan Demon Lord was extremely depressed in his heart, but there was no change in the expression on his face, making it difficult for Yin Rongyu to guess his psychology through his facial expressions.

"Yes. Yin Gengyu nodded.

"If that's the case, then you should wait for two days. The Demon Lord of Tianyuan had no choice but to agree.

Two days were spent in a long wait.

After Yin Gengyu cast a secret technique, he opened a direct channel to the Demon Domain.

The passage opened up by Yin Gengyu this time has a limited capacity, and it can only accommodate the weaker clones of demons such as the Tianyuan Demon Lord and the Red Sky Demon Lord to enter the Heavenly Pluto Star along the passage.

Yin Gengyu did this because he was worried that after letting the stronger guy of the Red Heaven Demon Lord come over, when the two of them communicated face-to-face, they would find out all his secrets, which would be unfavorable to him.

Only the weaker clones are allowed to come over, so when he communicates with the Red Sky Demon Lord and the Tianyuan Demon Lord, he can be unrestrained and don't have to worry about the opponent causing him trouble.

The passage opened, and the Heavenly Wall Demon Lord and the Red Heaven Demon Lord immediately followed the leading passage opened up by Yin Gengyu and entered a spatial area where the power of heaven and earth was completely shielded by the power of heaven and earth circled by Yin Gengyu's spell.

Seeing the Red Sky Demon Lord, the corners of Yin Gengyu's eyes twitched violently for a while, and he didn't know how to do it in his heart, and there was a very strong smell of danger, but he quickly walked out of the frightened state, and then put on a casual look, and said to the two: "Both of them are powerful people in the Demon Domain, and they are both smart people, I won't say more nonsense." ”

After saying this, Yin Gengyu didn't wait for the two of them to reply, and directly cast a secret technique, condensing the treasure refining secret method that shielded the power of Heaven and Earth into two knowledge runes, which were respectively taught to the Tianyuan Demon Lord and the Red Sky Demon Lord.

After obtaining the secret method of refining treasures, an excited smile immediately appeared on the face of the Red Sky Demon Lord, and then he said directly to Yin Gengyu: "You are really a genius treasure refining master, even such a strange treasure refining technique, you can think of it, if we let us explore it slowly, there are not three or five hundred years, I am afraid that we may not be able to think of refining treasures with this method to shield the power of heaven and earth on this planet." ”

"Now that the secret method of refining treasures is in hand, the next step is for you to find a way to refine the treasures yourself, as for what kind of treasures you will choose to refine for your own use, it is not within my consideration. I just hope that you will refine the treasure as soon as possible, in ten days at most, and then lead your Demon Domain masters to come to the Heavenly Pluto Star for revenge and deal with Long Fei. Yin Gengyu said.

"One more day if he lives, I will feel aggrieved in my heart. After I return, I will do my best to refine a treasure that can cover the power of the Pluto Heaven and Earth in the shortest possible time. Moreover, I will also go to the Fivefold Heavenly Demon Domain, go to a friend of mine, borrow a few masters with the same strength as this seat, and come with me to deal with Long Fei's hateful guy. At the mention of the name "Long Fei", the Red Sky Demon Lord gritted his teeth with hatred, and he couldn't wait to immediately arrest Long Fei, skin him, and eat his flesh before he was willing to be willing.

......

During the period when Yin Gengyu was trading with the Tianyuan Demon Lord and the Red Sky Demon Lord, Long Fei was not idle at all, he relied on the speed of his body to travel back and forth to the various continents of the Eastern Cultivation Holy Land, and directly sent Yin Rongyu to wreak havoc on the continents, attack and plunder the servants of all forces, and kill and wipe them out.

At this point, Yin Gengyu spent countless efforts to cultivate loyal servants on extraterritorial planets, except for a few people captured by Long Fei, almost all of them were wiped out.

And most of the disciples and disciples in the original Tianlong Fort force were killed, and only a very few people saw that the situation was not good, so they chose to flee as soon as possible and went into hiding, which was a lucky way to pick up a life.

It can be said that Tianlong Castle has no other living mouth except for Yin Gengyu, and Tianlong Castle has completely passed and become history.

In fact, in Yin Gengyu's heart, it didn't matter whether Tianlong Fort existed or not, because the purpose of his formation of Tianlong Fort was just to serve the plan he was secretly implementing.

Even if Celestial Dragon Fort still existed at the moment, it wouldn't help much for what he wanted to do.

Therefore, he didn't care about the life or death of the people of Tianlong Castle at all.

It's just that when he heard that Tianlong Castle had been destroyed, and that all his servants had been killed, and none of them were spared, he couldn't help but feel very annoyed in his heart.

Now, Yin Gengyu regrets it very much in his heart, thinking that when Long Fei was weak, he should have directly taken action to kill Long Fei, so his plan today may be able to be implemented smoothly.

"Whoosh!"

A figure swept through the void and instantly reached the sky above the Flying Dragon Castle.

This figure is none other than the lost dog Yin Gangyu.

He got the news that Long Fei was not in the Northland Continent at the moment, so he chose to come to Flying Dragon Castle, intending to take direct action to destroy Flying Dragon Castle, avenge his slaves and Tianlong Fort people, and take a bad breath for himself.

Yin Gengyu's appearance, he was meditating and practicing in the control center of the Guardian Sect Great Array, and his strength was compared to Long Fei today, he was a ghost spirit that was not strong or weak, and he immediately noticed it, and a contemptuous sneer immediately appeared on his face.

Just when Yin Gengyu cautiously approached the core station of the Flying Dragon Castle, intending to make a thunderous attack and kill the important people of the Flying Dragon Castle, the phantom spirit immediately controlled the Protector Array, and with the power of the formation, condensed a crystal sword, rushed out from the underground space, and stabbed directly at Yin Gang Yu.

"The Guardian Formation of the Flying Dragon Castle is so powerful!" Seeing the crystal sword slashing towards him, Yin Gengyu immediately caught a hint of danger, and his face immediately became extremely difficult to look at.

In addition to his state of mind, Yin Gengyu immediately took the Xuan-level sword in his hand, and danced in the air, splitting out more than ten sword rays one after another, forming a killing array, facing the crystal sword that flew towards him.
