"Actually, I don't know if I can find it, if I can find it, then I still have hope of recovery, if I can't find it, I estimate that I have a lifespan of several decades at most, in fact, this is not a condition, because I don't know if there is one in this star field." The old man did not answer Ye Kai's question directly, but looked up and said to himself.

Ye Kai didn't interject, he knew that the old man must be reminiscing about something.

The old man looked at the roof and was silent for a while before turning his head and saying to Ye Kai: "I want you to help me find three kinds of medicinal materials, if I can find all three kinds of medicinal materials, I can resume my cultivation, but you just need to help me pay attention to it in the future, I won't force you, because these kinds of medicine may not exist in this world."

The first type of blue-whiskered grass is blue and transparent, and you can see the flow of stem sap from the outside, and the flowers on it are like dragon's whiskers, as long as you can obtain the stem sap inside this grass, it is said that this sip can live the skin of the dead and restore the injured to their original beginnings.

The second is called the dragon raising its head, it is rumored that the first dragon in the fairy world dragon clan was the first to cultivate into an immortal, just because he inadvertently looked up and saw a red fruit when he was cultivating, and after eating it, he was immediately reborn and flew directly into an immortal, and later this fruit was called a dragon raising his head, but this kind of red fruit is also hard to find, this fruit can quickly restore personal cultivation, and if a healthy person eats it, he can immediately improve his cultivation.

The third kind is called Yin Yang Grass, it is said that this grass was formed at the beginning of the chaotic world, the leaves and stems are black and white, this grass can dissolve all the internal injuries on the human body, it can be said to be a healing medicine. ”

After the old man finished speaking, he glanced at Ye Kai, and then continued: "These are what I have seen from the classics, but in the past ten thousand years, Xiaoxia and his brother have almost traveled to most areas of the Immortal Realm, and they have not found it, so I hope you can help me pay attention to it in the future, and if I can't find it, I don't force it, that is what I am destined to be." ”

After hearing this, Ye Kai probably had a number, these medicinal materials are very rare, the old man hoped that if he could meet him when he was wandering in this immortal realm in the future, he would help find him, in fact, it was also an excuse for this old man to put it on the condition at all, so he said gratefully: "Old man, as long as I, Ye Kai, can be in this immortal realm for a day, I will definitely look for these three medicinal materials for you, you can rest assured." ”

The old man smiled and said, "It's enough for me to have your words, okay, don't talk about it, you stay with me for a few days first, and I'll teach you the hidden method first!"

"Old sir, I have been locked by those immortal guards, I am afraid that they will find this place and it will affect you. Only then did Ye Kai remember that he had already been locked by the Immortal Dao in front of him, and he might have already found it here.

"Don't worry, I've set up a formation in this valley, and anyone won't be able to find this place without my permission, unless you inadvertently break in from the ground like you, we won't live here for more than 10,000 years, otherwise my gangster would have come to the door a long time ago." The old man said with a smile, he was in a good mood at the moment because of Ye Kai's arrival.

"I see, the little one is arranged by the old gentleman. Ye Kai is relieved, otherwise he would really have to live in hiding outside in Tibet.

"Boy, since you have come to the fairy world, I will give you a suggestion, if you want to improve yourself quickly, then you should go to participate in the expeditionary force of the fairy world, only in that environment, can you train yourself. The old man then said to Ye Kai.

"Immortal Expeditionary Force!" Ye Kai was stunned, although he knew that it was composed of immortals who went to fight with the Demon Realm, but he really didn't think about joining the Expeditionary Force, because he had just arrived, and his cultivation was also low.

"Yes, because only in the endless killing can people grow, in some cultivation stars at the junction of the immortal realm and the demon realm, there are life-and-death battles every day, and the two sides really seize control of those cultivation stars, but you can rest assured, those above the level of Tianzun will not participate in that kind of battle.

Only when the army is against the army, the opponent's Great Demon God and the Heavenly Venerable of the Immortal Realm will come out to fight, as for the Emperor of Heaven and above, they will not participate, the two sides have an agreement, otherwise the Emperor of Heaven will already destroy those cultivation stars as soon as he makes a move, and he will really take something.

Therefore, now many major sects in the Immortal Realm will send their elite disciples to that kind of place to exercise, and the same is true in the Demon Realm, so that kind of place is the most suitable for cultivators to grow. ”

When Ye Kai heard this, he was immediately moved, this is really good, he can't escape for his life, he still has that confidence, and immediately asked: "Then how do I go to participate in this expeditionary force?"

"It's very simple, there is an expeditionary force immortal registration office in every city, you just need to find this place to sign up!" The old man was obviously familiar with this.

"Okay, I'll learn that hidden method here first, and then I'll go and sign up, and I'll be annoyed by those who guard the Immortal Dao!" Ye Kai immediately agreed.

The old man looked at Ye Kai with an approving gaze, this son is indeed not simple, it is not easy to be able to come here from a low-level cultivation star after cultivating for more than ten years, and now when he hears about participating in the expeditionary force, he is actually fearless, it is conceivable that as long as he does not fall in advance in the future, the future is limitless, and it is very likely to be able to help him leave this immortal world and go to a higher existence.

In fact, if he knew that because he couldn't cultivate on the earth, people put all their energy into studying and studying, so their minds were only more flexible than those in the fairy world, because the fairy world put all their minds on cultivation and neglected to learn and explore new knowledge, just like an athlete, he knew that if he didn't study, he would definitely lag behind the learner in many aspects in the future.

In the next few days, Ye Kai studied the cultivation book in his hand while learning the method of concealment from the old man, but he didn't have a clue at all.

A week later, Ye Kai had completely learned to master the method of concealment, which made the old man greatly appreciated, because according to his thoughts, it would take at least three months for Ye Kai to fully master it.

Three days later, Ye Kai was ready to leave, before leaving, Ye Kai took out a few Yirong Dan and gave it to the old man, and at the same time roughly explained the usefulness of this Yirong Dan, so that the old man was even more impressed, Ye Kai actually knew how to refine the pill, and this elixir cooperated with his concealment exercises, even if he stood in front of those people who guarded the immortal road, it was difficult to be detected, it was really wonderful, he specially asked Ye Kai for a few more, so that he could go out for a walk in the future, and he didn't have to hide in this valley all the time.

The old man also deliberately took out a storage bag and gave it to Ye Kai, although it was not the legendary storage ring or anything, but these storage bags were much larger than the inner space used by ordinary immortals outside, a full of hundreds of square meters, Ye Kai was not worried about having no place to put things in the future, and this bag was put into his arms after being stored, and outsiders didn't know it at all.

After Ye Kai thanked the old man, he was going to sign up for the expeditionary force, he got along with each other for the past few days, the old man made him very moved, a person who is not related to the old man helped him so much, he secretly swore that he must help the old man find the three medicinal materials, when he left, the old man taught Ye Kai how to arrange the hidden formation, and at the same time convenient for Ye Kai to find here next time he comes.

After saying goodbye, Ye Kai walked out of the valley through the formation, and when he went out, he looked back, the valley didn't exist at all, all he could see was a mountain forest, and the valley had been completely hidden by the formation, which was really magical.

When he came out, Ye Kai had already concealed his breath, and at the same time he was disguised as an old man, so that he didn't have to be afraid of the detection of those who guarded the Immortal Dao.

Crescent City is a medium-sized city more than a hundred miles away from this valley, this belongs to the Torimu Kingdom, and the Immortal Court has a recruitment office here, as long as you sign up here, you can participate in the expeditionary force to the Immortal Demon Battlefield.

When Ye Kai came to the conscription office, there were only a few people here who were in charge of signing up, and there were no immortals to sign up at all, at this moment he was worried about not being able to find the number of people to participate in the expeditionary force, and when he saw Ye Kai coming in, he immediately greeted him politely.

"I'm here to sign up for the expeditionary force, is there still a quota!" The old man dressed as Ye Kai stepped forward and asked directly.

"Yes, there are just three days before we have an expeditionary force to set off, just come to my side to sign up!" One of the middle-aged men hurriedly said, he was still afraid that Ye Kai would suddenly regret it, and took out something like a jade plaque as he spoke.

"You just need to make a mudra here, this is a kind of echo jade, which means that you voluntarily participate in the expeditionary force, life and death are fateful, the items captured on the battlefield belong to the individual, if you have killed the enemy, you can go to any registration office after returning to receive the reward according to your personal merit. The middle-aged man spoke quickly, and in a moment he had already handed the Shadow Jade to Ye Kai.

Ye Kai didn't hesitate, he directly pressed his handprint, and the man breathed a sigh of relief after watching Ye Kai press his handprint, handed Ye Kai a jade plate and said: "You put this brand away, it represents your identity, every time you kill someone on the battlefield in the future, this brand will automatically record your merits, if you accidentally fall, then the brand will automatically feed back your information to the expeditionary force headquarters." ”

Ye Kai took it and threw it directly into the storage bag without looking at it, and then asked, "Then where to gather and set off this time!"

"All you have to do is go to Babel City, find the recruiting office over there, show your token, and someone will naturally receive you. The middle-aged man explained carefully, for him, Ye Kai's joining, his pressure was reduced a little.

After Ye Kai roughly figured out the direction of Tongtian City, he left directly.

Just after he left, the person who had been watching and didn't speak on the side immediately communicated, "Hey! This person dares to participate in the expeditionary force with such a little cultivation, it is simply to send him to death, it is probably for the cultivation resources." One of the young men shook his head.

"I think it's very possible, it took him to cultivate to the peak of the Spirit Immortal at such an old age, and it is estimated that he was forced to make such a choice, who doesn't know the danger of the Immortal Demon Battlefield. Another middle-aged man took over and spoke.

"Ah Si, don't say it, be careful of being heard, if no one comes to sign up, our task this year will not be completed, whether it is life or death, it is their own choice, and we did not force them. The man who originally received Ye Kai said to the middle-aged man who was standing and chatting over there.
