Late at night, the infirmary was silent, save for the flickering lights on the tables.

"Why are you still so weak!" a familiar voice echoed in the sea of knowledge of Cangjian.

"Senior!" Cang Jian opened his eyes and shouted, but there were only him and Bai Xiaodong in the entire ward, and Ke Shaojing had already gone back to the dormitory, and there was no one else.

"I have no entity now, and I now dwell in your sea of consciousness. Don't shout loudly and silently in your heart, you can talk to me. The old man said.

"Senior, may I ask who you are?" Cang Jian shook his spirit and asked.

"It doesn't matter who I am, I'll tell you in the future, why didn't you cultivate the Eight Sects Quenching Pulp Sutra?" the old man's tone was a little angry.

"Uh...... I checked the requirements of the Eight Sects Quenching Meridian, and it requires a fifth-level pill [Tianshu Pulse Pill] to open the first realm, Yi Pulse. But I'm shy out of pocket right now, and I don't have that much money. "The Eight Sects Quenching Pulp Sutra is a Xuan-level advanced body training method, which has broken through the limit of the mainland's body training, and its cultivation conditions are also extremely harsh, even if the average person has not had a strong economic strength as support, there is no way to cultivate at all.

"It's a shame that you are still the young master of the Ice Spirit Clan, how did you end up like this, you can't afford a fifth-level pill. The old man fell into deep thought, and then said, "Well, I am helping you to devote all your soul power to the sea of knowledge." ”

Knowing the sea, is the storage location of people's knowledge and memory, the size of the sea of knowledge is determined by the strength of the soul power, Cang Jian is not the first time to come to his own sea of knowledge, every time he wants to fuse or read the memory of the Yuan Shen of Rahu, he needs to put the soul power into the sea of knowledge.

Now there are three things in his sea of knowledge, one is the ancient book of heaven, and he entered the sea of knowledge of Cangjian with Rahu's primordial spirit, and the other is Rahu's primordial god, Cangjian has not yet reached the realm of spirits, and has not been able to completely devour the primordial god that fuses Rahu, and the third is the mysterious old man.

He is a transparent old soul.

"I helped you devour his Yuan Shen, and you yourself have fused a third, what about your Chaos True Yuan Duel? The old man continued to ask, as if it was his elders checking the results of his cultivation.

"Why did you just replace the spiritual power and not condense the power of the Nine Suns?" the old man squinted his eyes and observed himself, and those small eyes seemed to see through himself.

"The power of the nine suns?" Cang Jian heard this term for the first time.

"My God, what kind of thing are you cultivating, the most powerful part of the Chaos True Yuan Decision, one is that it can cause the vibration of spiritual power, and the second is the power of Jiuyang. The old man said.

"What is the power of the Nine Suns? I haven't seen it in the memories of Rahu's predecessors. ”

"That's you, Chaos True Yuan, have never cultivated to home, after the Chaos True Yuan Decision is officially introduced, you can store the True Yuan in your dantian, and when you reach a certain level, you can form the Yang of True Yuan in your dantian. You can form up to nine, so you'll last up to ten times as long as your enemies in battle!"

"The power of Jiuyang is storage, you are storing your true essence all the time, when you fight, your spiritual power storage is several times that of the enemy, and the strength of your spiritual power is stronger than that of the enemy, so that you can be invincible. Even if you can't beat it, you can wear the enemy to death!"

"Uh...... The younger generation is ashamed of himself. Hearing this, Cang Jian had a new understanding of the Chaos True Yuan Decision, he originally thought that he had already touched the threshold, who knew that he had only cultivated some skins.

"Hey...... I really don't know what to say, but I'm in a hurry, I shouldn't have let you get in touch with the way of runes so early, which delayed your spiritual cultivation time a lot. Thinking of this, the old man frowned. "I've regained some soul power from my sleep in the past few days, but I can help you open the first page of this heavenly book. ”

"But after this time, I may have to sleep for another year or two, unless you get some soul-nourishing elixir. The old man said.

"Senior, why did you give me such an opportunity?" Although Cang Jian didn't know what the first page of this heavenly book was, he could be sure that it would definitely help him improve his cultivation. It was because of this ancient book of heaven that Rahu was besieged and killed by the enemy, and he was definitely not a mortal thing. Now the old man wants to help him open the first page, at the cost of him falling into a deep sleep, thinking of this, Cang Jian feels very uncomfortable.

"Hehe, you are really too weak, if you follow this rate, I don't know how long it will take for you to cultivate to the Spirit Sect, helping you is also helping myself. Cang Jian didn't understand too much, what the old man's last words meant, did he want Cang Jian to help him resurrect? This old man's state is a bit like the Yuan Shen, but he still has his own consciousness, not like Rahu, who has been dead for a long time, and the Yuan Shen has lost his consciousness.

"The first page of the Ancient Book of Heaven, called 'Time' which has its own space, you can enter it to cultivate, the time flow inside is different from the outside world, you have cultivated in it for ten days, and it is only one day outside, the next time we meet, the little guy will meet the sea of knowledge, I hope you have broken through to the spirit master. As he spoke, the originally transparent, old and weak soul suddenly became thicker, and one after another soul power impacted the ancient Heavenly Book, and the Heavenly Book, which had been silent in the sea of sword knowledge, finally turned its brilliant page.
