It is said that when Zhang Daoling Heavenly Master debuted, the world was in chaos, and the demons and monsters were rampant.

As for the "Book of Nine Ding Dan", this is the treasure that Taoist alchemists dream of, and it is said that the reason why Zhang Daoling Heavenly Master was able to refine the Dragon and Tiger Pill was because of this alchemy treasure.

Chu Wushi followed his master's cultivation, and he was already familiar with ancient books and ancient characters, and at this moment, no matter how he came here, he picked up the "Sword Seal Runic Record" and read it.

This sword seal rune tells the experience and experience of Taishang Laojun in inventing the rune, and it also tells the way of the method when portraying the rune.

It turns out that the depiction of the rune needs to be kept in the visualization, the purpose is to depict the natural power of heaven and earth, not only can be depicted on the yellow paper, everything in the heaven and earth can be depicted, as long as the mana allows, it is depicted in the air can also kill the enemy, but also can be integrated into the sword intent, can also be used as a pen, with the law as ink, with nature as paper, and the rune can be depicted at will for attack.

It can be said that to learn this sword seal rune, Chu Wushi does not always have to carry a brush rune paper all the time, and he can depict it at any time, and integrate the rune into the sword technique and body method.

Chu Wushi couldn't help but be fascinated, and whenever there was something unclear, he used a pen to depict a talisman in the air to confirm it.

I don't know how long it took for Chu Wushi to put down the "Sword Seal Rune Record". Chu Wushi has memorized all the content of this book, and in the future, he only needs to practice and confirm it with his experience.

Chu Wushi picked up the "Jiuding Dan Book" again and read it, this book was very difficult for Chu Wushi, not only was it obscure, but it was also unclear in many places.

This is not to blame Chu Wushi, although Chu Wushi has read a few books on Taoist alchemy, but he has not studied it at all, after all, the earth has entered the era of the end of the law, not to mention the elixir, even the old medicine of the year can not be found, can this condition still be called alchemy? It is a pharmaceutical, no different from a pharmaceutical factory.

Besides, if you want to refine the pill, you must understand the medicinal properties of various elixirs, Chu Wushi looked at it, just the lowest-level elixir mentioned in the "Jiuding Dan Book", the elixir needs more than a dozen kinds of medicinal materials, and Chu Wushi doesn't even recognize half of these medicinal materials, not to mention the dragon and tiger pills and higher-grade pills in the back, the elixir that will cost thousands of years at every turn, the inner pill bone marrow of the spirit beast and holy beast, where to find this thing? Unless you leave this world and go to the heavenly realm or the Pangu Continent.

Chu Wushi didn't care, just memorized it, in the words of the master, memorized, memorized it first, and when he understood it, he would naturally understand.

Chu Wushi was fascinated, and he didn't realize that there was an extra person at the door of the room.

When Chu Wushi was completely familiar with the "Jiuding Danshu", he found that there was an old Taoist at the door. I saw the old Taoist fairy wind and bones, fluttering clothes, floating dust in his hand, carrying a sword, white hair and childish face, and his appearance was almost the same as Zhang Daoling Heavenly Master in the stone carving just now.

"Little friend, the poor Dao is auspicious!" Old Dao nodded at Chu Wushi.

Chu Wushi saw that Lao Dao took the initiative to salute him, and hurriedly returned the salute: "Seniors are good! ”

"It's okay, it's okay, Xiaoyou and I have a fate, and it's God's will to be here. The old man is smiling, making people feel like a spring breeze.

"Senior, I don't know how to get here, seeing these two books, the kid is really hard to turn a blind eye, and I hope that my predecessors will forgive me!" Chu Wushi pointed to the two ancient books on the table, peeking at other people's secret books is a big taboo for cultivators, Chu Wushi doesn't know how to explain to Lao Dao.

"It doesn't matter, since you see it, it's your own chance. Lao Dao flicked his hand, and the two bamboo slips on the table were scattered with the wind.

"Thank you seniors, dare to ask the seniors?" Chu Wushi Lao Dao flicked his hand, and the bamboo slips disappeared, I don't know how deep the old Dao Dao method is.

"It's been too long, I've forgotten the name for a long time, how about Xiaoyou take a look at this sword?" Lao Dao took off the sword behind his back, put it on the table, and stretched out his hand to signal Chu Wushi to take a look.

Chu Wushi looked at the sword, and was shocked again, the hilt of this sword was almost exactly the same as his own sword, but the end of the hilt was inlaid with a ruby, Chu Wushi took it in his hand, and pulled it out, only to see that it was exactly the same as his own sword body, and the sword body was engraved with the word "Killing Spirit".

Chu Wushi stretched out his hand and pulled out another one, this sword was engraved with "Killing Evil", but the hilt was inlaid with a blue gem, and the length of the sword body was a little shorter than the sword body engraved with the word "Killing Spirit".

"Senior, isn't this the real three-five male and female slashing spirit sword?" Chu Wushi was a little regretful, it seemed that his own one was really a fake.

"Yes, this is the three or five male and female slashing spirit sword, the slashing spirit sword restrains the spiritual power of the world, and the evil sword restrains the evil in the world, the combination of the two swords is infinitely powerful. Lao Dao stood up and waved his hand, and the Evil Sword disappeared, leaving only the Spirit Slaying Sword, but the ruby on the hilt of the Spirit Slaying Sword was missing.

"Could it be that the predecessor is Zhang Daoling and Zhang Tianshi?" Chu Wushi was shocked, these two swords were Zhang Tianshi's personal swords, no wonder Lao Dao was so similar to the figure of Lao Dao in the carved picture he saw.

"Yes and no! I'm just a wisp of obsession, and now the end of the world, I haven't met you until now, and it's also the will of God. "The old man bowed.

"Zhang Tianshi is above, please bow to the younger disciples!" Chu Wushi didn't expect that it was really Zhang Tianshi, according to the teacher's inheritance, Chu Wushi was also a disciple of the Heavenly Master's Dao, although he didn't know which generation of disciples he was.

"Little friend, don't be polite, hurry up, I'm just an obsession, I don't know much, you can ask any questions you want!"

"Senior, why did the Human Realm enter the Age of the End of the Law, and where did the gods of the Heavenly Realm go?" Chu Wushi wanted to know very much at this moment was why the gods of the Heavenly Realm had disappeared.

"I don't know the specific reason, I'm just an obsession, I just know that the heavenly realm has been extinguished!"

"Do the predecessors know where the gods of the Heavenly Realm have gone? Could it be that they have all died out with the Heavenly Realm?" Chu Wushi really couldn't believe how powerful the gods of the Heavenly Realm were, not to mention the Three Qings and Six Emperors, they were the gods and Buddhas of the Heavens, how prosperous and boundless their mana was, how could they let the Heavenly Realm be extinguished.

"I don't know very well, the death of the Heavenly Realm is so sudden, most of the gods have fallen, and a few powerful gods and Buddhas, some may have gone to other worlds, and some may have been wandering outside the Three Realms. Lao Dao was extremely sad at the moment, lonely, his eyes were cloudy, full of powerlessness and loss.
