Chen Feng was puzzled again: "Lao Tzu killed all the masters in the world, so that he can be carefree, isn't it good?"

The Spirit of the Book smiled, "It's too easy for you to think about it. First of all, it is true that no one in the world can defeat Lao Tzu, but this is a one-on-one situation. No matter how powerful Lao Tzu is, can he still deal with thousands of troops? Secondly, he pretended to die a thousand years ago in order to concentrate on exploring the true immortality, so how can he have time to kill irrelevant people?"

In the end, the spirit of the treasure book said to Chen Feng again: "As for you, since you first came out of the rivers and lakes, what you have shown is also the mastery of today's martial arts factions. If I directly teach you the kung fu of the Five Thunder Transformation Pole Hands, the Interception Dao Fingers, and the Nine Xuanhua Dao Hands, Lao Tzu will definitely pay attention to you. But by now, he should know that I'm in your consciousness. It's just that he mistakenly thought that he had killed you, and he knew that he couldn't do anything to me, so he left me alone. I tell you everything now because you are the only one who can defeat Lao Tzu, and I believe in you!"

"Thank you for your trust, but there's one thing I can't figure out. Since Lao Tzu already knows the method of immortality, why should he study it?"

"You were beaten stupid by Lao Tzu, didn't you? He continued to study precisely because there is no real method of immortality in this world......

The spirit of the treasure book patiently explained, it turned out that the blood of the dragon turtle only has the effect of prolonging life, which can keep you alive for thousands of years. But there's no guarantee of your status. In other words, you have lived for a long time, but your martial arts will gradually lose and you will slowly become an ordinary person.

Lao Tzu did maintain his martial arts, which was the result of years of study. He has developed an elixir that can maintain your strength after eating it, and it will also allow you to continue your cultivation.

It's just that when he reaches the realm of Lao Tzu, his martial arts can't improve much.

Speaking of that elixir, its main ingredient is an extraterrestrial element. To put it bluntly, it is necessary to use extraterrestrial meteorites and then refine medicines.

However, meteorites outside the sky do not fall every day, so Lao Tzu has been paying attention to the celestial phenomena every day and night for a long time. Whenever a meteorite fell from the sky, he rushed to the scene to collect it as soon as possible.

The elixir made by refining the extraterrestrial elements has a shelf life. As long as a few years pass, the elixir will be ineffective, so no matter how much elixir you hide, it will be useless.

Lao Tzu has to take a pill every year, in case there is no extraterrestrial meteorite landing for several years, his skills will be greatly affected, so that any person who understands martial arts may be able to kill him, and the importance of this extraterrestrial meteorite to him is self-evident.

"The Seven Divine Swords and the Seven Divine Weapons are all forged from the material in the meteorites outside the sky, no wonder Lao Tzu wants to get them, it turns out that they are just to extract the elements to make pills!" Chen Feng suddenly realized.

But the martial arts treasure book said: "You are wrong, if he is just to get the meteorite outside the sky, why don't he snatch it at the first time, but let the Tibetan Sword Villa and the Famous Weapon Villa get it?"

"Yes, why is that?" Chen Feng asked curiously.

"Because he has been researching for many years, he finally has some eyebrows!"

It is impossible for Lao Tzu to put all his hopes on the meteorite outside the sky, just like the white-robed Yin Emperor that Chen Feng saw in the reincarnation gate underground palace, which is the person of Lao Tzu's experiment. For thousands of years, he has been doing research, so he hasn't harmed martial arts much.

Coincidentally, it was in this era that Chen Feng traveled to, and Lao Tzu happened to discover something. It's just that the spirit of the treasure book has a relatively limited understanding, it can know the affairs of the world, but it cannot see the thoughts of a person.

Lao Tzu knew the ability of the spirit of the treasure book, so he only hid the secret of his research in the bottom of his heart, and the spirit of the treasure book naturally could not be detected.

Judging from all kinds of clues, the spirit of the treasure book speculated: "When the extraterrestrial meteorite forging the Seven Divine Swords and Seven Divine Weapons came, Lao Tzu did not go to snatch it, but was neutralizing the blood of the phoenix and the blood of the dragon turtle. ”

"Wait, you said that the blood of the phoenix is also in Lao Tzu's hands?" Chen Feng was shocked, and he was also a little desperate.

The Spirit of the Book said embarrassedly, "I'm sorry, I forgot to talk about it. The blood of the phoenix is indeed in Lao Tzu's hands, and now he is the only one who has the blood of the phoenix in his hands. The reason why the white-robed Yin Emperor in the reincarnation gate underground palace was able to survive with a single head was actually the effect of the blood of the phoenix. When I was with him, I collected almost all the treasures in the world. But because the blood of the phoenix and the blood of the dragon turtle conflicted with each other, there was only one choice, and Lao Tzu finally chose the blood of the dragon turtle......"

For a long time, Lao Tzu was trying to find a way to neutralize these two divine bloods, and add other precious things to transform and improve.

And when the recent extraterrestrial meteorite arrived, Lao Tzu was at a critical moment in his research.

"In that part of the blood of the dragon turtle and the blood of the phoenix, he added the blood of many rare beasts and some precious medicinal materials, and finally he should have completed the research, otherwise he would not have come to look for extraterrestrial meteorites. I think the extraterrestrial element should be the final synthetic, but the amount of extraterrestrial elements he needs is huge, so he has to collect all the seven divine swords and seven artifacts. He didn't dare to try it casually until the collection was completed, because it was very likely that these extraterrestrial elements would be wasted. ”

"Most of your speculations are true, I didn't expect your brain to be quite powerful!" Chen Feng quipped.

"I'm sorry, I don't have a head, just a wisp of consciousness like you now. ”

At this moment, the voice of the white-haired old man came in: "Little Brother Chen, how are you recovering now?"

Chen Feng's conversation with the Spirit of the Treasure Book could only be terminated, and the things he wanted to know were basically known, and there was no need to continue talking. The only thing to think about now is how to get the blood of the phoenix!

"Senior, I have absorbed all the medicinal power, as long as my body continues to freeze, I will be fine for a short time. It's just ......"

The last sentence Chen Feng really can't say, how powerful is Lao Tzu? Do you want everyone to fight with Lao Tzu for their own sake?

"Little Brother Chen, tell me the whereabouts of the blood of the phoenix. You have done too much for the Martial Arts Alliance and for this country, and now it is time for us to do something for you. No matter what the danger is, we are willing to go!"

"The blood of the phoenix is in the hands of Lao Tzu. Chen Feng finally said it, but added later, "Lao Tzu is too strong, and the martial arts alliance has no chance of winning." ”

The white-haired old man said, "Little Brother Chen, I know that you are thinking about everyone, but don't underestimate us. That's right, Lao Tzu's martial arts are indeed powerful, but there are so many masters in our martial arts alliance, and they are not vegetarians!" ......
