Back in the cave, after Sima Yuan and Wu Xin took a breath, they fell into a crazy 'cultivation'.

It doesn't stop until you're exhausted.

Greedily gasped for breath, and after a moment of warmth, he began to double cultivate.

Double cultivation is not a joy of fish and water, but a mutual complement with their own exercises.

Of course, Wu Xin naturally benefited the most.

After all, who asked Sima Yuan to keep Danzhu awake.

However, he is not without gains, after all, Wu Xin, who has maintained a 'virgin body' for 10,000 years, has brought Sima Yuan unparalleled benefits.

At least the other party didn't treat him badly, and almost half of the life essence and origin essence were transferred into Sima Yuan's body.

His cultivation was already on the verge of the early stage of Da Luo, and even in the Hengyuan Sect, he had already touched the threshold of the middle stage, but he had never broken through.

The reason why Sima Yuan was willing to contribute to the Flying Spirit Gate this time was that in addition to wanting to find a quiet place to break through, he wanted to use the huge pure immortal qi of the Heavenly Firmament Realm.

With this position of worship, you can steal its immortal spirit in the open.

Of course, before the retreat, Sima Yuan also got angry with the head Zhang Yin, bluntly saying that this time it was possible to break through the middle stage, and if there was an emergency, please bear with him.

Zhang Yin thought it was a big deal, waved his hand, and said arrogantly: "Don't worry, Shanmen will deal with all the situations." ”

Sima Yuanxin put it back in his stomach, and thus fell into the longest retreat since the monastic path.

It was a full retreat for 300 years.

This retreat was not a spotless meditation and double cultivation, Sima Yuan had also gone out to breathe qi, and even visited Elder Yan.

The two had an in-depth exchange on revenge, well, nothing else.

After all, he Sima Yuan is not a good worm, and he will not forcibly accept the other party.

Besides, after all, she is a married woman, no matter how lustful he Sima Yuan is, he will not refuse to come.

So it's really just a simple exchange.

However, Wu Xin didn't believe it, and even went there in person several times after that, but in the end he still didn't find anything, so he went back to retreat suspiciously.

During this three-hundred-year retreat, Sima Yuan did a lot of things.

The first thing to do is to improve your attacking skills.

Now the attack technique in his hand is only the Xuanyuan Sword, which is too single, and it also damages the Xuanyuan Sword too much.

After all, there are many opponents, and there is only one helper, and Sima Yuan is also very helpless.

In the cave, with a bang, Sima Yuan sacrificed the Xuanyuan Sword.

The sword aura was overflowing, and the light was shining.

After a gentle tremble, a color of joy seems to reach the heart.

Sima Yuan smiled: "It's been hard for you all these years."

Xuanyuan Jian trembled with joy, as if in response.

After many years of companionship, we have long been in touch with each other.

Moreover, the sword body of the Xuanyuan Sword and the sword spirit are integrated and will not be separated.

It's like embarking on the road of 'merging'.

The sharpness of the sword depends on its toughness and resistance ability in the mortal realm, but after entering the fairy realm, it is different.

In this way, when the monk is envoy to the 'flying sword', he will go from 'art' to 'Tao' and step to a new level.

Since Sima Yuan obtained the 'Ask Immortal Sword' back then, the Ask Immortal Sword Spirit in it was limited by Sima Yuan's 'spell' and could not exert its greatest power.

After that, Sima Yuanxiu rose step by step, until he became an immortal, and the flying sword also became a 'fairy sword'.

The things that have been refined have also changed from spiritual objects to immortal things, and now with Sima Yuan to the point where he is today, he has become a 'Taoist soldier'.

Dao soldiers, Dao Divine Soldiers.

And he is also a Taoist soldier of 'the sword falls and the road does not fall, and the spirit of the road does not die'.

Xuanyuan Sword is such a Dao soldier.

This is also the reason why it has been on the battlefield for a long time, and it has always existed after a long period of destruction.

Even the more opponents Sima Yuan encountered, the stronger the Dao soldiers became.

However, now in Sima Yuan's opinion, the Xuanyuan Sword has been tempered to the extreme, and if there is no additional opportunity, I am afraid that he will not be able to be promoted to the rank.

If the Dao soldiers want to be promoted, ordinary immortals naturally can't, unless there are supreme immortals in the Daluo Realm, it is difficult to succeed.

Sima Yuan remembered the 'Chopping Sendai', and since it was destroyed, he had always regretted it.

There is also a golden hoop stick that was also placed in the fairy domain by Sima Yuan to assist his son Sima Yan and daughter Sima Yue to guard the Quartet.

With that divine weapon in hand, even if the new demon emperor of the demon clan attacks, there is no need to worry, it is enough to resist.

Sima Yuan secretly breathed a sigh of relief, these were naturally already arranged.

He glanced at the Xuanyuan Sword, and after a moment of deep thought, he decided to try a new way.

He said softly to himself: "Old man, you and I have been together, and we have long been inseparable from each other, and today I will pass on my great way to you and help you become enlightened." ”

Xuanyuan Sword trembled slightly, and a look of joy came out.

As soon as Sima Yuan's words fell, the Xuanyuan sword suddenly passed through his chest.

The sword qi is full, cleansing the internal organs.

The Danzhu in the sea of knowledge trembled slightly, as if he had disdain.

But Xuanyuan Sword is like a little fan brother, always pestering Danzhu around.

Sima Yuan's eyes were solemn, and he snorted lightly, as if there was endless mystery.

The entire heaven and earth had the Great Dao Xuanyin appearing, surrounding Sima Yuan's side.

Sima Yuan's mind seemed to have the past, love and hatred, power and profit, and life and death.

These scenes are not only Sima Yuan's avenue, but also Sima Yuan's past.

They carry everything in Sima Yuan's past, and they are full of 'sentient ways'.

His eyes were dark and he muttered to himself.

The murmur wafted out, and the lotus flowers around Sima Yuan were flying, and the shadows of the Dao were staggering.

The lotus of the avenue bloomed, and the flowers of eternal life bloomed one after another.

His gaze was clear, and through the many barriers, he went straight to the deepest part of his heart.

There, there was a thin, lonely, frightened little figure.

He is the young Sima Yuan.

It all starts here.

The avenue naturally arises from here.
