Holding the booklet tightly, Sun Yan's mind couldn't calm down for a long time, the purpose of this planetary air battlefield can be said to have been fully achieved. The final whereabouts of Uncle Sun Lie's blood have also been discovered, and if these relics are brought back, Uncle Ancestor will be able to return to his hometown.

It's just that the ninth level of [Forging Yuan Jue] is actually a deadly martial art, and if this news spreads, it will definitely set off stormy waves.

Thinking of this, Sun Yan couldn't help but sigh, for tens of thousands of years, how many peerless Tianjiao have reached the realm of eight forgings, and they all dream of impacting the nine forgings, laying an incomparably majestic foundation, and impacting the peerless martial sect in the future, and even the realm of supreme immortal martial arts.

But now, once such a fact is known, what kind of impact will it have on people? At least Sun Yan himself cannot be at peace in his heart.

Continuing to flip through the booklet, Sun Yan wanted to see what else his uncle had recorded. If there are any unfulfilled wishes in the starry sky battlefield, Sun Yan intends to fulfill these unfulfilled wishes.

"What's going on!"

Sun Yan suddenly showed a look of shock, the content behind this pamphlet was Sun Liexue's inference about the cause of his immortality, and in the last few years of his old age, almost all the reasons for his immortality were deduced.

The real reason is because of this stone page, Sun Liexue said in the booklet, it is precisely because he has comprehended some martial arts principles on the stone page that his strength can enter the realm so quickly.

In Sun Liexue's later years, he learned some big secrets of Fengyun City, and finally deduced that he cultivated the ninth level of the [Forging Yuan Jue] and died without exploding, precisely because of the stone pages, or rather, because he had cultivated some martial arts on the [Heavenly Dragon Secret Classic].

"[Celestial Dragon Secret Archive]...... Is this stone page one of them......"

The texture of this stone page is very strange, and it is as cold as jade to the touch, and I don't know what kind of stone it is made of. It was only one page, and its weight was close to 100 catties, so you can imagine how heavy it would be if it was the entire [Heavenly Dragon Secret Codex].

Regarding the legend of the [Secret Book of the Heavenly Dragon], the golden giant ape has also been mentioned, this is the treasure of the town of the Celestial Dragon clan, with many other names, and it is also the strongest classic of the Celestial Dragon clan.

In the past, the last emperor of the Tianlong clan relied on the [Tianlong Secret Codex] to cultivate the realm of immortal martial arts, fought against the heroes on Tianlong Mountain, and killed thousands of peerless martial sects.

And the martial arts foundation of the original Dragon Lord was also from the [Heavenly Dragon Secret Codex], so Sun Liexue realized in his later years that it was precisely because he cultivated a page of martial arts in the [Heavenly Dragon Secret Codex] that when he cultivated the ninth level of the [Forging Yuan Jue], he did not explode and die, but only the Yuan Power was exhausted.

“...... , Tracing back to the source, the martial arts created by the Lord of the Absolute Dragon later are from the same source as the [Heavenly Dragon Secret Classic], and the [Forging Yuan Jue] must be the same. It's a pity that I am not the true descendant of the Lord of the Absolute Dragon, and I forcibly cultivated the ninth level of the Forging Yuan, and ended up with the end of the Yuan power......"

In the second half of the booklet, Sun Liexue finally understood in his later years that if he wanted to cultivate the ninth level of the [Forging Yuan Jue], he must first comprehend the technique of sealing the dragon.

On the other hand, the martial art of [Forging Yuan Jue] is actually for cultivators of the Dragon Sealing Technique. Even, the entire starry sky battlefield was also prepared for the cultivators of the Dragon Sealing Technique.

“...... , if you can comprehend the true dragon sealing technique, the cultivation of [Forging Yuan Jue] may be able to achieve it in a very short time. It's a pity that the skill of immortal martial arts is hard to find, even if you can really find it, can you really comprehend it......"

In the booklet, when Sun Liexue wrote these words, he was full of self-deprecation and sighing. The realm of immortal martial arts is the realm of many warriors' dreams, but how difficult it is, let you have peerless talent, martial wisdom and godliness, throughout the ages, there are a few people who have climbed to this realm.

At least, in the known history of the Humanoid Alliance, there has never been an official record of the immortal martial powerhouse, and the supreme powerhouses such as the Lord of the Absolute Dragon, the Dark Thunder Emperor, and the Sword Monarch are only in the ethereal rumors.

At the end of the booklet, in addition to the summary of Sun Liexue's life's martial arts, there is also a record of the ninth cultivation key of the [Forging Yuan Jue]. In addition, Sun Liexue also made many improvements to the Ninth Layer, hoping to be able to cultivate to restore his strength.

It's a pity that these improvements turned out to be useless in the end, after all, it was the martial arts of the Supreme Immortal Martial Arts, and how could other martial artists change it at will.

Closing this booklet, Sun Yan held the stone page in his other hand, and his chest was agitated, for other martial artists, it might be hopeless to impact the ninth level of [Forging Yuan Jue].

However, for Sun Yan, this should be the best gift left by Sun Liexue.

Sun Liexue spent all his time in his later years to prove that the ninth level of the [Forging Yuan Jue] is only suitable for the cultivation of martial artists who comprehend the skill of sealing the dragon, and he also left this stone page.

At the end of the booklet, there is also a summary of Sun Liexue's martial arts in his later years, leaving behind a combat skill - [Qianyang Earthquake World Fist]!

"[Qianyang Earthquake World Fist]!" Sun Yan was deeply shocked.

This combat skill is even more sophisticated than the martial arts of the "Divine Skill List", and it is infinitely close to the martial arts mastery, which was finally deduced by Sun Liexue in his later years.

It is mentioned in the booklet that the creation of [Qianyang Earthquake World Fist] is that together with Wu Yanqiao and Bai Shura, the three of them each created the prototype of a peerless martial arts.

Wu Yanqiao created the [Floating Light Earthquake Heaven Technique], and Bai Shura was the [Demon Puppet Control Yuan Gong], and the three of them created these three martial arts at that time in the hope of going out from the starry sky battlefield in the future to revitalize the martial arts civilization of the Earth Alliance.

It's a pity that Sun Liexue stayed on the starry battlefield forever and never returned to his hometown for the rest of his life.

"[Qianyang Earthquake Fist], [Floating Light Earthquake Technique], [Demon Golem Control Yuan Gong] ......"

Sun Yan was extremely emotional in his heart, thousands of years ago, the Great Martial Sect Wuyanqiao Martial Arts Dacheng abandoned the [Floating Light Earthquake Heaven Technique] that became famous, and its intention has always been different.

Because in the past, the terrifying [Floating Light Earthquake Heavenly Technique] shocked even the super-first-class civilization race. Later, countless people felt that if Wu Yanqiao could perfect this combat technique, the emperor style and martial arts, maybe there would be one more martial arts master.

Perhaps, Wu Yanqiao abandoned it at the beginning, I am afraid that he knew that his friend could not turn back, so he finally sealed this skill.

And Bai Shura's [Demon Puppet Control Yuan Gong] was obtained by Wei Wuxing and General Wei, but the world didn't know what martial arts Wei Wuxing was good at.

Time flies, the ancestors who created the three kinds of martial arts, have they ever thought of today's situation?

Stroking the relics of Sun Lie's blood, Sun Yan was stunned, thinking of the demeanor of his uncle, Wu Yanqiao and others, he couldn't help but be a little fascinated. It wasn't until his shoulders moved slightly and the puppy Lele turned over in his sleep that Sun Yan came back to his senses.

Holding this booklet, Sun Yan decided to start cultivating the ninth level of [Forging Yuan Jue], and only by cultivating this martial art could he fulfill his uncle's wish.

Placing the stone page in front of him, Sun Yan calmed his mind and began to follow the Yuan Force recorded in the booklet, and began to impact the ninth realm of [Forging Yuan Jue]. At the same time, he was calm, fixing on the stone page, which was the way to comprehend its contents.

Rumble!

The stone pages of the book shone brightly, and pictures appeared in Sun Yan's mind, the Yuan Force in his body was running like a turbine, constantly compressing and strengthening under the full speed of the Seven Yuan Force Pools.

A misty mist of Yuan Force rose from his body, enveloping Sun Yan in it, and the transformation speed of the Dragon Yuan in his body was getting faster and faster, and he was about to reach a critical point.

Behind him, the dragon-shaped light and shadow appeared, as if pulled by some kind of suction, sinking little by little, submerging into Sun Yan's body, and a strange fusion with his body.

Bang......

The light and mist in the sky poured out, enveloping the ninth floor of the entire Wind Tower, Sun Yan only felt a roar in his mind, and the whole person fell into an unconscious state of concentration, and the Yuan Force in his body instinctively operated, becoming more and more condensed, and flowing out of a golden texture......

Next to him, the little puppy Lele lay on the ground, the little guy was really tired, looked up at the owner, felt that there was no danger, so he fell asleep and never wanted to move again.

......

Seven days later, Teng Wanxi, Duan Rutian and others came to the eighth floor of the Wind Tower, waiting for Sun Yan to appear.

In the past seven days, Teng Wanxi and others have come almost every day, and they stay for a whole day, and for them, such a wait is worth it.

If Sun Yan could climb to the ninth floor of the Wind Tower and bring back the cultivation tips of the ninth level of the [Forging Yuan Jue], it would change the history of martial arts of all races. On the contrary, if Sun Yan did not succeed and did not even come back, then Teng Wanxi and the others would have to consider leaving the starry sky battlefield.

After all, this black-haired boy was the most outstanding of the martial artists of Fengyun City for a long time, and he comprehended the technique of sealing the dragon. If even Sun Yan doesn't succeed, others can no longer have illusions.

This kind of waiting is a torturous process, but Teng Wanxi and others waited for the answer they wanted.

In the early morning of the seventh day, they saw the familiar figure of the black-haired boy at the entrance of the deep staircase.

Sun Yan returns from the ninth layer!

This news was enough to shake the entire Fengyun City, and Teng Wanxi and the others were even more ecstatic, could it be that Sun Yan also brought back the ninth cultivation key of the [Forging Yuan Jue]?

However, the black-haired boy just smiled and handed the pamphlet left by his uncle to Teng Wanxi and the others, gathering the crowd to watch.

After a while, everyone fell into silence, tens of thousands of years of longing, wanting to hit the ninth level of the [Forging Yuan Jue], the truth turned out to be so!

However, such a truth is cruel, but for Teng Wanxi and others, it is not unacceptable. A long time ago, the various super-first-class civilization races had discovered that the existence of the starry sky battlefield was likely to be the heir of the Dragon Lord.

After a long time, after recovering from the shocked feelings, Teng Wanxi made a decision, about the secret of the ninth level of the [Forging Yuan Jue], only everyone present knew about it, and it was not allowed to be leaked. In particular, the three major imperial forces must not be known, so that the attention of the imperial clan can be distracted.
