Lingquan is a spring with a very high concentration of spiritual energy in heaven and earth.

If it is on the surface of the earth, the aura of heaven and earth in the spiritual spring is easily emitted between heaven and earth.

As a result, the vast majority of spiritual springs are located underground, and once exposed to the surface, the spiritual energy will slowly emit and eventually turn into ordinary spring water.

During the period when the underground spiritual spring had just been exposed to the earth, because of the emitted aura of heaven and earth, the quality and concentration of the aura of heaven and earth nearby were extremely high, which was very suitable for the cultivation of martial artists, and the cultivation speed was much faster than the cultivation of refining pills, which was an unavoidable opportunity.

Returning to the Yuan Realm martial arts, the stronger the true qi accumulated in the body, the more hope there is to break through the True Dan Realm, looking at the underground spiritual spring that suddenly appeared, everyone present was very happy and excited.

If they could cultivate near this spiritual spring, they could greatly speed up their breakthrough through the True Dan Realm.

Even Sun Buju, who was already in his fifties, was full of excitement, he was old, even if he absorbed the pill to cultivate every day, he no longer had the strength to break through the True Dan Realm.

But......

The quality of the heaven and earth aura in the underground spiritual spring is much higher than the quality of the heaven and earth aura contained in the pill suitable for his cultivation, if he absorbs this heaven and earth aura to cultivate, maybe he will be able to bloom in the old tree, and before entering the old age stage, there is a possibility of breaking through the true pill realm.

Although the Guiyuan Realm has lived for more than 100 years, it is actually still the longevity of a normal person, even if it is an ordinary person who does not cultivate, some well-maintained people can live past a hundred years old.

But the True Dan Realm is different, the True Dan Realm has a longevity of more than two hundred years, and if you can live past two hundred years old, your longevity has doubled.

Life is short, just a hundred years old, how can you see the beauty of this world?

The ascension of Shou Yuan is the driving force behind the cultivation of martial artists, and it is also the reason why all Guiyuan Realm martial artists want to break through the True Dan Realm when they sharpen their heads.

As soon as the underground spiritual spring was born, Sun Buju no longer had the idea of killing Yun Fan alone, he didn't want to waste the heaven and earth spiritual energy in the spiritual spring when he was fighting with Yun Fan.

Sun Buju shouted: "All up, slaughter this kid, let's hurry up and cultivate next to the spiritual spring." ”

Yue Rulong, Xuan Zhankun...... The other five people were all looking forward to Sun Buju's sentence, and they all looked excited, and their momentum exploded to the extreme, and they each showed their best martial arts and attacked Yunfan.

The corners of Yun Fan's mouth were filled with a disdainful smile, and as soon as the underground spiritual spring came out, he knew that this battle should be over.

The aura emitted by this underground spiritual spring was enough for him to quickly break through to the peak of the Returning Yuan Realm.

Xuanyue's big mudra, you can cultivate slowly, and the opportunity to encounter the underground spiritual spring is difficult to have again, Yunfan didn't want to waste time, and pressed the X-301 mecha bracelet on the wrist of his right hand with his left hand.

Click-

Before everyone could get close to the attack, X-301 was already equipped, and Yunfan turned into an iron giant.

Bell Bell Bell –

The attack of the six men slammed into X-301 with a crisp sound.

X-301 has no sparks on his body, and his body is not moving.

X-301 tonnage 16, weighing 32,000 catties, Yun Fan controls X-301 to that station, it is not a power-type attack, even if it is standing still, it is not something that a Guiyuan Realm martial artist can shake.

"You're the Iron Man?"

"Are you the ironclad man who snatched the jasper spirit fruit in the Luoshui Mountain Range?"

Xiao Shuihan and Jiang Lengyue exclaimed at the same time, in the Luoshui Mountain Range, both of them had seen the power of the iron armor with their own eyes.

However, now Yunfan is equipped with X-301, which is one level higher than the X-201 equipped at that time, although it doesn't seem to have changed much, but its strength has increased more than ten times.

Even if it is X-201, it has a crushing advantage in the face of the martial artists of the Guiyuan Realm, and Xiao Shuihan and Jiang Lengyue still have lingering fears about the strength of the ironclad people.

"It's your honor and your misfortune to see my hole cards!"

Yun Fan's voice came from X-301, his voice was indifferent and full of murderous intent: "This mecha is my protector, who once killed a Zhendan powerhouse, and against you, it is to kill chickens with a knife!"

Sun Buju had never seen the power of the mecha, and shouted: "What are you afraid of, it's just a pair of battle armor, but it's just a strong defense, let's go all out and take his life with the least amount of time." ”

X-301 turned his head, and Yun Fan's gaze locked on Sun Buju: "You are the first!"

As soon as the words fell, X-301 rushed forward, leaped over the crater, and appeared in front of Sun Buju in the blink of an eye.

This speed is beyond the reaction ability of the Wu Qian of the Guiyuan Realm.

X-301 stretched out his right hand and slapped it from the sky!

Sun Buju suddenly showed a look of horror, he wanted to resist, but before the sword in his hand could be put on the shelf, he was slapped on the head by an iron palm.

Bang –

The top of Sun Buju's head was slammed, blood splattered, and his entire head was slapped into his chest.

Hiss –

Yue Rulong, Xiao Shuihan, Xuan Zhankun, Jiang Lengyue, and Zhao Yunxiao all gasped, their expressions instantly turned into horror, and the hair on their bodies exploded.

Sun Buju has cultivated the pinnacle of the Guiyuan Realm of top-grade martial arts, and in terms of strength, he is better than the five of them, and he is the first outer sect elder of the Great Luo Sect!

But after Yun Fan wore this set of armor, he didn't even have the slightest resistance, and was slapped to death?

These five people are all elites and geniuses in the sect, and they have had a smooth life, have never encountered any major setbacks, and have never experienced life and death dangers.

At this moment, the five people looked at X-301 with a frightened expression, their hearts trembling, and their legs almost paralyzed.

However, the desire to survive made them still retain some strength, and quickly turned around and ran.

X-301 stepped forward and punched out, hitting Zhao Yunxiao in the back, and the terrifying power penetrated Zhao Yunxiao's chest, blasting the clothes on his chest.

Zhao Yunxiao vomited blood in his mouth, was blown away more than ten feet away, and died with one punch.

X-301 took another step forward, slapped down with one palm, and slapped Xuan Zhankun's head, Xuan Zhankun was the same as Sun Buju, his skull was shattered, and his head was slapped into the chest with terrifying power, and he was killed by the same blow.

Immediately afterwards, it was Xiao Shuihan, Jiang Lengyue, and Yue Rulong!

Yun Fan controlled the X-301, killing one step at a time, only five steps, Zhao Yunxiao, Xuan Zhankun, Xiao Shuihan, Jiang Lengyue, and Yue Rulong were all killed with one blow, and all of them died.

With X-301 in hand, even in the face of an army in the Returning Yuan Realm, Yun Fan can sweep and kill a few people, as easy as a hand, like a leisurely stroll.

Yun Fan manipulated X-301 to dig a big hole, and the corpses of the six people were all gone, and the space rings of the six people naturally fell into Yun Fan's hands.

Then, Yun Fan washed the X-301 with spring water and put the X-301 away.

The spiritual spring has just been born from the ground, the spring water is connected with the air on the surface, and a large amount of heaven and earth spiritual energy is emitted into the air.

Yun Fan sat on the ground in this spiritual energy mist area, cultivating the 'Returning to the Yuan Chapter' of the Great Luo Treasure Book, frantically absorbing the surrounding heaven and earth spiritual energy, and seizing the time to cultivate.

The surrounding aura frantically poured into Yun Fan's body, and it was visible to the naked eye that the aura mist next to Yun Fan formed pillars of spiritual energy, quickly drilling into Yun Fan's body from all the tricks of Yun Fan.

Most of the heaven and earth aura emitted by the underground spiritual spring was absorbed into Yun Fan's body, refined into true qi, and quickly strengthened his cultivation.

Every minute, every second, Yun Fan could feel the growth of the true qi in his body, and with this kind of cultivation speed, it would not take him ten days and a half months to be able to ascend to the peak of the Guiyuan Realm.

If it is to cultivate the spiritual energy between the heaven and earth of the Qianyuan Continent, Yun Fan will cultivate to the peak of the Guiyuan Realm, not to mention it will take several years, and cultivate next to the underground spiritual spring, and the speed will increase by more than a hundred times.

Yun Fan frantically absorbed the rich aura of heaven and earth around him, and his mood was extremely comfortable, this underground spiritual spring saved him several years of hard work.

If he is lucky enough to obtain the treasure medicine that breaks through the True Dan Realm in the Medicine Mystery Realm, after Yun Fan leaves the Medicine Mystery Realm, as long as he obtains a technique to break through the True Dan Realm, he will be able to start breaking through the True Dan Realm.

The True Dan Realm is equivalent to the three-flower gathering of the ancient martial arts of the earth!

If Yun Fan breaks through the True Dan Realm and returns to the earth, the Yun family will immediately be promoted to a second-class family, and Yun Fan will also have the strength to compete with the second-class family.

There are too many heaven and earth spiritual qi emitted by the underground spiritual spring, and Yun Fan can't absorb it completely, and there are still a lot of them spreading into the distance, slowly dissipating between heaven and earth.

Many of the nearby martial artists sensed the aura fluctuations and rushed here back and forth.

The first to arrive were the three elite disciples of the Tianyang Sect in Xuanluo Prefecture.

"It's an underground spiritual spring!"

"Wow...... That rebellious disciple of the Da Luo Sect, he actually enjoyed the underground spiritual spring alone?"

"Kill him, this underground spiritual spring belongs to us!"

As soon as the three of them arrived, they shot one after another and killed Yun Fan.

Yun Fan's eyes widened, and the essence of light burst out, full of killing intent.

Without using X-301, Yun Fan only cast the Xuanyue Great Mudra and killed the three of them.

Dig a pit and bury the three of them, and Yun Fan continued to cultivate.

Soon, someone sensed that the aura fluctuations were coming here!

......

The disciples of Xuanluo Prefecture and Xiyuan Prefecture, who entered the Medicine Mystery Realm, all appeared in the nearby area within a radius of 100 miles, and all of them were attracted by the spiritual energy fluctuations emitted by the underground spiritual spring.

The first thing the disciples of the sect who came to the underground spiritual spring was to kill Yun Fan, but as a result, they all died at Yun Fan's hands.

The disciples of Xuanluo Prefecture and Xiyuan Prefecture were all wiped out in the Mysterious Realm of Medicine!

After killing for a whole day, finally no one came to fight, and Yun Fan continued to cultivate.

Yun Fan absorbs a large amount of heaven and earth aura every day, and cultivates for thousands of miles a day, thirteen days later, Yun Fan's true qi has been qualitatively improved, and his cultivation has also made qualitative progress, reaching the peak of the Guiyuan Realm.
