Yueyun hesitated for a moment, but decided to speak.

"The stakes are very high, and only a handful of people know about it, and even many old monsters in their infancy are only half-understood. Listen carefully to what I am going to say, and decide not to pass it on. ”

Seeing Yueyun's serious appearance, Han Tu's heart sank, this was the first time he had seen the former so serious. What's the secret in this?

For a while, Han Tu asked with some regret. When he knew this secret, he was trapped with Yueyun. At least in this Sword Immortal Domain, he needs to act with the other party.

However, after thinking about it, Han Tu still decided to listen to it first.

"I want to hear about it. ”

Yueyun nodded, and then spoke.

"The Sword Immortal Domain has existed for countless years, and the number of times it has been opened is incalculable. The magic weapons in it have been explored by the predecessors, and all that is left are some immortal grasses that continue to grow over time, and sword beasts that the Sword Immortal Domain defends itself. ”

Speaking of this, Yue Yun paused and said with a heavy face.

"In addition, the Sword Immortal Domain actually has a crucial secret, and that is the inheritance!"

Han Tu has also heard similar words like "inheritance?" Most of the time, it will be used when the master needs to recruit disciples to take over his mantle.

Could it be that the owner of this Sword Immortal Domain can't find a successor? If this is true, it is indeed a shocking secret.

However, Han Tu did not ask about the conditions of inheritance, but asked about his previous concerns.

"In that case, then why do you insist on finding the evergreen grass?"

"Because the evergreen grass is the first step to start the inheritance. ”

Yue Yun suddenly took out an ancient book sewn from cowhide from the spirit sac, and some paintings were drawn on it with some special materials. Although the lines are simple, they are vivid and accurately express their meaning.

In the center of the picture is a white-veined and extremely complex magic circle, surrounded by ten long-lived grasses. The evergreen grass in these paintings is no different from what Han Tu had seen in the sky city before, except that there seems to be a single circle of gold around the former.

Immediately afterwards, Yueyun turned a page of the ancient book and revealed a new picture.

When these Immortal Grasses were placed on the magic circle, with a gust of wind, long swords corresponding to their number suddenly appeared around them and landed on the back of the Immortal Grass.

And in the next painting, these swords change their bodies. This change was different from the sword beast that Han Tu had encountered earlier. If what he encountered before was transformed by sword qi. The sword beast in the painting in front of me is the sword itself that has evolved through some kind of rules.

When the page was turned again, these sword beasts also completed their own changes, revealing their respective appearances. And Han Tu also became extremely shocked at this time.

Some of the sword beasts in this painting remain animalistic, while others still take on the form of humans. Moreover, two of them were also familiar to Han Tu, who were the two people who had fought at the gate of the cave before.

In addition, these sword beasts are also painted with special symbols on the top of their heads, which are several blue paths, a little blue water droplet, a golden pill, and a pattern that resembles a baby.

Previously, Han Tu did not understand the meaning of these symbols. But the more he looked at it, the more he felt that something was wrong. But soon, he suddenly brightened up, revealing a look of understanding the scroll. But soon, his expression changed back to astonishment.

"Isn't it ......"

Han Tu muttered.

Could it be that on this scroll, the mysterious pattern on the top of the sword beast's head refers to the failure of cultivation? the blue Dao is similar to the air flow, referring to the Qi refining period, the blue water droplets are the spiritual energy compressed into a liquid state, referring to the foundation building period, and the golden pill is the golden pill stage that most immortal cultivators are extremely eager for.

And that baby, I'm afraid, is that infancy......

Seeing that Han Tu had understood, Yue Yun flipped it again, revealing a new picture.

A white blank space appeared above the sword beasts, and there were some special words written on them. However, these questions are not suitable for the use of these people, so Han Tu does not know any of them.

On this page, the sword beast's expression also changes, and it turns in a different direction. At first glance, it looks as if these sword beasts are talking to each other.

Talk to each other?

Han Tu's head buzzed. Doesn't this mean that these sword beasts in the painting are already self-conscious? the unconscious sword beasts before have already made them anxious. This is a few sword beasts with consciousness, and then there is really no place to die.

"Miss Yueyun, could it be that these immortal grasses are the key to starting the inheritance?"

Yueyun nodded.

"That's right, among the many long-lived grasses, there are also some golden root long-lived grasses. And these long-lived grasses are the first part to start the inheritance. ”

Hearing what the other party said, Han Tu finally understood why the other party was so obsessed with the Immortal Grass.

"But the strange symbols in that painting really represent cultivation, except for the four Qi refining periods and the three foundation building periods. There are also two knotting periods, and one yuan infant stage. It seems that the two just now are in the Dan period. And the Dan period is so strong, let alone the Yuan Infant Period. That's an existence that even the real Yuanying Immortals don't want to face. Even if you find it, you won't be able to attract the sword beast!"

Yueyun said very seriously.

"When you try to pull up the evergreen grass, or when you have this thought in your heart, a sword beast will come. These golden root grasses are naturally immune to most spells, and their branches and leaves are as tough as magic weapons. What they summoned was a fixed cultivation sword beast. Therefore, if the cultivation is not correct, it will not be able to trigger the necessary conditions for summoning sword beasts. ”

Hearing this, Han Tu frowned slightly.

"In that case, why do you want to try it when you know it's dangerous?

At this moment, Yue Yun suddenly picked up a green gem and pressed it on her arm. Immediately afterward, she burst out with an irresistible momentum from Han Tu, just like ...... It's like a meta-infancy!

Han Tu's cold sweat came down, he knew from a very early age that some magic weapons could conceal his cultivation. Could it be that the moon rhyme in front of you turned out to be an old monster in the infancy stage?

In this way, under the other party's young appearance, is it actually a thousand-year-old, or even 10,000-year-old monster?

Seeing Han Tu's expression, Yue Yun immediately understood what he was thinking, and said unhappily: "You are an old monster, your whole family is an old monster!"

Forehead...... Hehe, Han Tu sneered.

Since the other party will still joke like this, it means that she is not in the infancy stage.

Yue Yun shook the gem on her arm and explained.

"Actually, the reason why I can change my breath is mainly because of this. ”
