The Nine Yang Immortal Jade Emperor Sutra contains the power of the Nine Yangs, which is the Immortal Sutra created by Jiang Yuhuang's ancestor, and cultivating to the extreme is the Dao of Yang, which is incomparably powerful.

Especially in the Nine Yang Nine Revolutions, after the mana in the body is compressed nine times, it will reach an extremely terrifying realm.

Jiang Sinan planned to see if he could cultivate the Nine Yang Immortal Jade Emperor Sutra before going to the Outer Heaven Battlefield, and if he could compress the mana, it would be regarded as adding some combat power.

After all, the battlefield outside the sky is full of crises, and there are hundreds of tribes outside the territory, not to mention the kings and emperors, I am afraid that even the supreme strong have a lot, Jiang Sinan's current combat power plus some hole cards, there is no problem in dealing with the emperor, but it is not the opponent of the supreme powerhouse.

Jiang Sinan has now opened up the space of 129,600 acupuncture points around his body, his mana is incomparable, and he has the foundation to cultivate the Pure Yang Jade Emperor Sutra, with his current understanding, it is not difficult to cultivate the Nine Yang Immortal Jade Emperor Sutra.

However, this method of Jiuyang and Nine Turns is too perverted, with his current realm, he has been in retreat for more than three months, and he is only worthy of completing the cultivation of the first turn, but he is stuck on the bottleneck of breaking through the second turn.

"It seems that if you want to break through the second turn, it can't be achieved in a short time!"

Jiang Sinan woke up from his cultivation, and now his breath was all in his body, like an ordinary person, but there was a glint in his eyes, and it became more and more profound and mysterious.

Huang Tianyi has also been out of the customs, since Huang Tianyi Phoenix Nirvana broke into the Imperial Road Realm, even Jiang Sinan is a little unable to see through the realm of Huang Tianyi, the whole person has become ethereal and hazy, more and more unfathomable, like a fairy in the Moon Palace, left behind and independent.

This time he went to the Outer Heaven Battlefield for trial, and Jiang Sinan was going to take Huang'er, Li Jinlong, Shenwa and Master Rabbit together.

Li Jinlong has cultivated the Divine Rune Sutra, although it is only the cultivation of the top king, but there should be no problem in dealing with the average beginner emperor, and the two wonders of the god baby and the rabbit master do not have to worry, as long as they do not encounter the supreme powerhouse, it is not necessarily who suffers.

Although there are many strong people in the Outer Heaven Battlefield, the supreme powerhouses are not cabbages, they can be seen everywhere, so take them with them, Jiang Sinan doesn't have too much to worry about.

"Sinan, you're finally out of the customs!"

As soon as Jiang Sinan came out of the customs, he saw Jiang Yuqing, Jiang Yan'er and Jiang Tie waiting in the Lingxin Pavilion.

The three of them originally had anxious looks on their faces, but when they saw Jiang Sinan and Huang Tianyi, they immediately showed a relaxed smile.

"Is something wrong?"

Jiang Sinan asked with some confusion, it seems that Jiang Yuqing and the three of them seem to have been waiting for themselves for a long time.

"Sinan, there is a change in the battlefield outside the sky!"

Jiang Yuqing said with a somewhat solemn expression: "Just a few days ago, the foreign races didn't know why, and they went crazy and attacked my Sun Holy City, and the eight clans of the Heavenly Emperor Mountain have already sent the elite people of each clan to the Sun Holy City to defend, we originally planned to go to the Sun Holy City here, but fortunately, Sinan you are out of the customs, this time we can go together!"

"Alien aliens storming the Sun Holy City, do you know what the reason is?"

Jiang Sinan's eyes were shocked, he didn't expect the current situation to become so critical.

These days, Jiang Sinan finally understood that the Sun Holy City was not the city of the Jiang clan, but a defensive holy city in the Outer Heaven Battlefield, which was jointly guarded by the eight clans of the Heavenly Emperor Mountain.

The Sun Holy City was built by Jiang Yuhuang Ancestor more than 10,000 years ago, and it has become an immortal holy city in front of the hundreds of extraterritorial races, and no alien race can enter the primordial world through the Sun Holy City.

Every Holy Land Immortal Gate has its own cities guarded on the Outer Heaven Battlefield, and these city defense lines block the offensive pace of the Hundred Extraterritorial Clans, and at the same time, the Holy Land disciples can also go out to the Outer Heaven Battlefield to kill foreign races and sharpen their cultivation through these Holy Cities.

Jiang Yuqing shook his head and said: "No one knows the reason, maybe only the hundred tribes outside the territory know, we go to the Outer Heaven Battlefield to experience this time, I am afraid that it will be unprecedented danger, Sinan, you must also be mentally prepared!"

"I've long wanted to see the Outer Heaven Battlefield, Brother Yuqing, I'm ready to go to the Sun Holy City this time!"

Jiang Sinan smiled slightly.

"Okay, then, let's go now!"

Jiang Yuqing, Jiang Yan'er, and Jiang Tie all glanced at each other, and then everyone came to the inner city of Yujing City, where there was a teleportation array that led directly to the Outer Heaven Battlefield.

"Dad, I heard that foreign races are all treasures, what dragon liver and phoenix marrow, bird's nest bear's paw, Dad, let's hurry to the outer heaven battlefield and kill a few more aliens to try it!"

The goddess did not realize any danger, but cheered and was full of anticipation.

"That's right, that's right! It is said that foreign races will have some precious medicine kings, and even holy medicines, Master Rabbit, I am tired of eating them, just to change the taste!"

Master Rabbit grinned, and there was a touch of humanized expectation on the rabbit's face.

"You two better be careful! The Outer Heaven Battlefield is very dangerous, if you are noticed by the Supreme Strong, you can't run away!"

Jiang Sinan glanced at the two of them angrily, but his eyes were also full of smiles.

Everyone didn't seem to be aware of the impending danger, but their expressions were very relaxed, and they entered the teleportation array together, and after a bright light flickered, several of them disappeared into the void.

In the Yujing City, on top of a misty mountain peak, Jiang Taizhen looked at the figure of Jiang Sinan leaving in the distance, and said with a somewhat anxious expression: "Patriarch, why did you agree to Jiang Sinan to go to the Outer Heaven Battlefield?

Jiang Taiyi stood with his hands in his hands, surrounded by clouds and mist, looking like Yue Zhi Yuanlin, and his bearing was extraordinary.

Hearing this, he smiled slightly and said, "It's too true, your heart is upset!"

Jiang Taizhen said angrily: "Patriarch, how can my heart not be messed up, this is a peerless genius comparable to Jiang Yuhuang Ancestor, if it really dies in the hands of a foreign race, my Jiang clan can't bear it at all......"

"Taizhen, you have to know that my Jiang clan boy stands up to the sky, and he fights for a piece of heaven and earth with his own hands, although Jiang Sinan's talent is not weaker than Jiang Yuhuang Ancestor, but if he wants to achieve the achievements of Jiang Yuhuang Ancestor, I am afraid that it is extremely difficult, he must go to the battlefield outside the sky, to experience those tests of life and death, and only between life and death can there be breakthroughs and enlightenment!"

Jiang Taiyi sighed and said: "Although this time the foreign hundred races are in danger, it is also an opportunity for them, and I believe that Sinan, he will definitely be able to walk out of his own way! Besides, if it really doesn't work, Taichong is also in the Sun Holy City, with him to take care of it, Jiang Sinan will not have any problems!"

Hearing Jiang Taiyi say this, Jiang Taizhen also smiled bitterly, he didn't expect Jiang Taiyi to really use foreign races as Jiang Sinan's whetstone, but what he was most worried about in his heart was that the whetstone was fine, and if the knife was broken, it would be troublesome!
