In the past three years, Lin Xuan has suffered from damaged meridians, and every time he recovers, it takes a long time to recuperate, and as an ordinary person without a spiritual root, it is difficult to keep up with the footsteps of his peers if he works hard, where is there still time to delay.

Lin Xuan carefully controlled the speed of spiritual power flow, but fortunately, after continuous attempts, he was already very clear about the endurance of his meridians.

An hour later, the cycle was completed, and the spiritual power returned to the dantian from the meridians.

After checking it with internal vision, a wisp of gloom flashed in Lin Xuan's eyes, he had worked so hard, but his cultivation had not changed, it stands to reason that if he did a big week, his spiritual power should increase more or less.

It seemed that he had no choice but to refine his heart, Lin Xuan gritted his teeth.

Refining Heart Road, is a special place in the Drifting Cloud Valley, three thousand years ago, by the patriarch of this sect accidentally discovered, after investigation, it is determined to be the relics left by the ancient monks.

It was a very wonderful place, as long as you entered it, you would be wrapped in illusions, one moment in the sword mountain and the sea of fire, and the other time into the eighteen layers of hell, although the illusion will not cause real harm, but it will make people miserable, but the benefits are also obvious.

Although the path of refining the mind is terrifying, the aura inside is very sufficient, and practicing there can have twice the result with half the effort.

Moreover, for the disciples of this sect, the path of heart refining is free and open, but unfortunately, except for the masters above the foundation building period, the low-level disciples in the spirit stage do not dare to try it at all, with their cultivation, the Dao heart is unstable, and they can't withstand the invasion of illusions at all.

But now Lin Xuan had no other way to go, either stuck in a bottleneck, or go to the heart refining road to seek a breakthrough, he chose the latter.

Pushing open the heavy stone door, Lin Xuan walked out of the practice room, at this time the sky was already completely dark, and the stars blinked weakly, but Lin Xuan did not plan to rest, like refining the heart and leaving.

In the mountain behind the Drifting Cloud Valley, a slanting passage on the stone wall is bottomless, this is the Heart Refining Road, standing at the entrance, Lin Xuan took a deep breath and walked in.

In the first hundred meters, there was no illusion, and the concentration of heaven and earth aura was exactly the same as outside, but Lin Xuan didn't dare to be careless at all, although it was the first time to come, but on weekdays, he had heard of the terrible way of refining the heart.

After taking a few more steps, the situation suddenly changed, and the aura of the surrounding heaven and earth became thicker, and this place was indeed suitable for cultivation.

Lin Xuan's expression became solemn, and he looked around carefully before carefully sitting down on his knees.

Rumble!

Flames suddenly erupted from the surface, and the temperature around them suddenly increased......

The terrifying scene appeared, Lin Xuan raised his eyebrows slightly, did not panic, turned a blind eye, and still absorbed the surrounding aura wholeheartedly, everything that happened in the heart refining path was all an illusion, and he didn't need to pay attention to it.

However, although he knew that it was fake, it felt like it was real, and soon the flames raised the temperature around him to an unbearable level, and large drops of sweat dripped from Lin Xuan's face.

Hearsay is really completely different from personal experience, in the past, Lin Xuan just listened to those masters of the foundation building period talk about the heart refining road, but he didn't expect it to be even more terrifying than the legend.

Soon the flames burned to his body, and with the cultivation of the first layer of his agility period, he couldn't release the shield, so he could only grit his teeth and endure it.

While enduring the pain of burning his body in the flames, he also had to concentrate and absorb the aura of heaven and earth, the tribulation was unimaginable to ordinary people, but Lin Xuan relied on a tenacious perseverance to survive.

The flames licked the skin, Lin Xuan's teeth rattled, and the pain was so painful that the back had become numb, but the aura here was indeed sufficient, and the absorption speed was several times that of the outside.

Although it was an illusion, it felt like a real purgatory, honing Lin Xuan's perseverance.

Absorbing the aura into the body is only the first step, and then it is necessary to refine them one by one according to the secret method taught by the master, which will have a lot of loss, usually absorbing hundreds of milliliters of spiritual energy, and at the end of the day, it can only refine the spiritual power the size of a hair.

Then the obtained spiritual power will be operated in the eight veins of the Qi Sutra, and the most dense will be stored in the dantian.

Even if it is a person with a strong mind, it is impossible to complete the whole process in the flames, Lin Xuan persisted for five minutes, his endurance had reached the limit, he stood up, and ran out of the fire as fast as he could, and when he left the area with sufficient spiritual energy, the Agni Illusion also disappeared.

"Sure enough, it's the same as the legend. Lin Xuan checked his whole body, and there was not the slightest scar, but the pain of being burned by the fire just now still made him remember it vividly.

Although it is uncomfortable, it is also worth it, because the spiritual power here is not only highly concentrated, but also very pure, and cultivating here can have the effect of getting twice the result with half the effort, and the hope of breaking through the bottleneck has greatly increased.

After resting for a while, Lin Xuan stepped forward again, and the flames resurfaced, enduring the pain of being burned, and continued to absorb the spiritual energy.

When his stamina reached the limit, he ran out of the palace to rest for a while, and after recovering his strength, he re-entered the Flame Illusion Realm.

In this way, the cycle began again and again, Lin Xuan relied on his perseverance to practice hard in the path of heart refining.

......

A few days passed, and his spiritual power finally had some growth, although the harvest was still very small compared to what he had paid, but compared to practicing outside, it was much faster.

At this rate, as long as you persist, you should be able to enter the second layer of the agility period.

Silently calculating the progress of his cultivation, Lin Xuan stood up, he had been on the Heart Refining Road for four days, he should go out to take a look, first, he has been sleepless for the past few days, cultivating in the flames, his body has reached the limit, and second, today is the time for the chair to teach the exercises.

According to the rules of Piaoyun Valley, every four days, a master of the foundation building period will be preached like a disciple of the spirit period, and with the guidance of the master, there will be many detours in cultivation, and Lin Xuan will naturally not miss such an opportunity.

Following the passage, Lin Xuan came outside, and unlike when he came, he happened to meet a cultivator in the foundation building period.

"Uncle Shi!"

"...... you" The man glanced at Lin Xuan, his face full of surprise: "You went to the Heart Refining Road?"

"Yes, Uncle Shi. ”

After the two broke up, the monk in the foundation building period was still in a daze, although the illusion would not cause real harm, but the feeling was exactly the same as the real one, a disciple in the early stage of agility could actually endure it, and the perseverance of this son was really amazing.

In addition to spiritual roots, cultivation also requires mental toughness, this disciple named Lin Xuan is really different!
