The Chaotian Immortal Venerable used his spiritual pupil to see Duanmu Xiaotian's move, and the Yin Void Immortal Thunder rune was unleashed, turning into the lightning of the Yin Void Immortal Thunder and slashing out. Duanmu Xiaotian continued to draw talismans in the air, and at the same time walked out of the area surrounded by Yuan Magnet.

The Yin Void Immortal Thunder Rune he cast floated in front of him, and then he cast five Five Elements Thunder Rune Seals to bless the past, thus forming a powerful Thunder Gang Cover. Above the canopy, the power of the Yin Void Immortal Thunder and the power of the Five Elements Thunder wanted to merge, so the power of protection became even stronger.

After Duanmu Xiaotian left the land of Yuan Magnetism, he resisted for a while with the power of six thunder runes outside. Chaotian Immortal Venerable carefully watched the Yin Void Immortal Thunder Rune, and decided that this was the real Yin Void Immortal Thunder Rune, and couldn't help but be shocked, and said: "The Yin Void Immortal Thunder Rune, after hundreds of thousands of years, finally reappeared. Since Yu Bai, including the immortal realm, there is no Lei Xiu who can master the Yin Void Immortal Thunder Rune, and today he was actually mastered by this kid. ”

"Ancestor, doesn't there be such a rune inheritance in the immortal world? Doesn't it mean that the Thunder Fairy has mastered the power of the thunder of Yin and Yang, and she can use the Chaos Immortal Thunder. ”

"It's different. The Mixed Heaven Immortal Venerable immediately responded, "The rune is the path of the Great Dao Pattern, and it is the most primitive power that is exerted. There are a total of nine heavenly and earth thunders, and the first one is a chaotic immortal thunder that was born when the chaos of each space world was not opened, thus awakening the chaotic world. The second is that the chaotic space opens the heavens and the earth, thus turning the chaotic space into the world of heaven and earth, followed by the five elements of yin and yang thunder. There are many creatures who can master the power of these thunderbolts in the immortal world. But the Nine Thunder Runes, then they have to be comprehended from the original thunder. The Five Elements Thunder is good to say, it can find the original thunder meaning, and the other four will only appear when the Great Heaven and Earth World is first opened, especially the last two are even more impossible to find. The Nine Thunder Runes were originally realized by the power of the Immortal Realm when the mortal world was opened up in the early primeval period. Later, the inheritance of the Nine Thunder Runes fell into Yu Bai's hands, and the Xuantian Rune Sword contained the will of the Nine Thunder Runes, which was the original meaning of thunder. It is estimated that this kid just induced the will of the Yin Void Immortal Thunder rune in the Xuantian Rune Sword when he was comprehending the Yin Void Immortal Thunder, and this allowed him to master it. ”

"I see, Brother Duanmu has mastered the Yin Void Immortal Thunder Rune, and it is estimated that he can help us leave the Yin Sky Thunder Ze. ”

"It's hard to say...... Although the Yin Void Immortal Thunder Rune is powerful, there is no high or low immortal-level power, and it is only the power of the Dao intent of the caster, and now this kid's Dao Intent of the Yin Void Immortal Thunder is not strong enough. At the center of the cloudy day Thunder Ze, I can feel a sense of crisis, I'm afraid it's not so easy! Fortunately, the Heavenly Thunder Sect didn't trigger those arrangements, which is a good thing for us. ”

As soon as the Chaotian Immortal Venerable finished speaking, Duanmu Xiaotian over there retreated to the place surrounded by Yuan Magnet. This time the resistance time is much longer, that is to say, Duanmu Xiaotian can also resist in the central area for a quarter of an hour with his own strength, after the power of the rune is consumed, Duanmu Xiaotian can't draw the Yin Void Immortal Thunder rune in the air in a short period of time, so he can't resist it and retreats back.

Duanmu Xiaotian wanted to try his hand again, but at this time, the Chaotian Immortal Venerable shouted for him to return. Duanmu Xiaotian knew that the Chaotian Immortal Venerable would definitely have to guide him, so he returned directly to the area guarded by the formation without saying a word.

"Boy, yes, this is the mastery of the Yin Void Immortal Thunder Rune. I just resisted hard outside for a quarter of an hour, and it seems that the power of thunder is much stronger. ”

"Hehe......" Duanmu Xiaotian smirked a few times, looking more proud, "It really feels good to master the Yin Void Immortal Thunder Rune." However, the juniors have just mastered it now, and they are not yet proficient, so I don't know what advice the Xianzun seniors have when they call the juniors to return. ”

"Thunder stuff, who can advise you. The Mixed Sky Immortal Venerable glanced at him and didn't care about anything, "I called you back because your two humane intentions and strength have improved a lot, so you should not be in a hurry to continue to improve, you should move forward and try the depth of the center point of the cloudy Thunder Ze." If you kid want to continue to improve in the trial, it is the same after the center point. Besides, it's not that easy to get through. ”

Chaotian Immortal Venerable was worried that Duanmu Xiaotian would misunderstand what he meant, so he explained it very clearly.

"Immortal Venerable Senior is right. Duanmu Xiaotian nodded and looked at Chitian, "Brother Chi, then you and I will repair it and go on the road, and see where we can travel this time." ”

Chitian had already discussed it with the Mixed Heaven Immortal Venerable, so naturally he had no opinion. After Duanmu Xiaotian finished speaking, after repairing for a long time, the two of them went on the road, and the formation of the Yuan Magnetic Land was still not taken away.

Once again, it was at its previous limit, about eight hundred miles from the center. The last time they were here, Duanmu Xiaotian and Chitian felt a lot of pressure, and they couldn't stay long. Now that my strength has improved and come back again, I obviously feel different.

Duanmu Xiaotian drew talismans in the sky, drawing Yin Void Immortal Thunder Runes, and the other five Five Elements Thunder Runes directly used runes to bless their own Thunder Dao Intent. After all these years of trials, Chitian's physical body has become much stronger, and the power to control feng shui is also much stronger.

In this way, the increase in strength allows them to move on. The speed in the early stage was not slow, it was very cold and I walked a hundred miles, and the pressure I felt in the back became stronger and stronger. And on the cloudy sky, Lei Ze seemed to have sensed it, and the power of the Yin Void Immortal Thunder converged.

It was so difficult that the two of them marched forward for two hundred miles, and the distance of two hundred miles took them a month, very slowly.

It is still five hundred miles away from the center point, and although it is constantly replenished with elixirs to maintain its own strength, it can't hold on anymore, and the power ahead is too strong.

Just when Duanmu Xiaotian and Chitian wanted to move forward and try the limit of what they could walk, they had just crossed dozens of zhang when suddenly there was a roar from the front. The power of the thunder caused by the concussion became even more violent, and Duanmu Xiaotian and Chitian Zhen were pushed back, and the means were exhausted, and under the power of the three quasi-immortal levels, they retreated several miles before they stabilized their bodies, and Duanmu Xiaotian and Chitian were injured by the power of the violent thunder.

"What is that? Could it be that there are still living beings in the center of the cloudy sky?" Chitian asked, not knowing who he was asking, but his eyes were always on the front anyway.

Duanmu Xiaotian seemed to know, and muttered: "Thunder Spirit, the spirit creature born from the thunder, how can this Thunder Spirit be so powerful." ”

"That's right...... It was Thunder Ling. In ancient times, Lei Ze gave birth to thunder spirits on cloudy days, but they were taken away by the trialists before they could grow up. Cloudy Sky Razor has been occupied by the Heavenly Thunder Sect for so many years, haven't they found out?"
