The purple flame ignited, and the air above the flame dome seemed to become transparent, indicating the terrifying temperature of the flame. The flames wrapped the greenstone in it, and for a while the purple and green intertwined, so it was not dazzling, but the purple was too unstable, as if it was blowing with the wind, flickering bright and dark.

Li Hetu's forehead was sweating, and the internal force around his body was surging a lot, and he couldn't support it for a while. I have been practicing for many years, and my internal strength accumulation is not weak, even if I am at the top of the ranks among the mortal martial arts, I can't support the kung fu of this purple flame with a stick of incense, it is really because the internal force required to maintain this purple flame is too amazing, and it is simply to the point of appalling.

I felt that my whole body was paralyzed, and I couldn't exert my strength, and the true power in my body was actually consumed by the purple flame. The air in the room was extremely hot, as if if a breath of air from here was about to burn all the internal organs, which was extremely uncomfortable. Li Hetu barely stood up and looked into the furnace, but this look made Li Hetu overjoyed.

Under the scorching of this purple flame, the surface layer of the greenstone finally liquefied slightly, and the changes were so small that they could not even be observed with the naked eye. But what kind of person is Li Hetu, when the sword-casting master who sits on the second and first place today, except for a few old things that have long retired in the Wanjian Villa, it is not impossible to say that he is the number one sword-casting master at that time. After all, Li Hetu is the only person in Wanjian Villa who has honed his fire resistance technique to the realm of "condensing flames into purple" in the past hundred years.

Li Hetu found the slight changes between the surface layers of this greenstone, and no matter how weak the degree of liquefaction was, it also proved that this greenstone can be condensed. Even the purple flame smelting this greenstone is so difficult, which just proves that its material is extraordinary. Of course, there are also many factors that Li Hetu's "Purple Flame" realm is not yet stable.

Although Condensing Flame into Purple is only the highest realm that can be cultivated in just over 200 words, it is the same realm, and there is a world of difference between the first glimpse of the path and the consummation of Dacheng. Legend has it that this purple flame realm is cultivated to perfection, which can make the flame purple all over, inextinguishing or dispersing, and burning all things. It's not just the flame top with a purple light.

Li Hetu wanted to take advantage of the fact that the liquefaction of the surface layer of the greenstone had not yet condensed, so he hurriedly took it out and refined it. After all, with his current attainments in fire resistance, he is still far from condensing the true purple flame, and wanting to refine this greenstone as a whole is like a fool's dream. Only by taking advantage of the faint liquefaction gap to temper it, and accumulating over time, can this sword forge have a chance to shine.

It's a pity that although this policy is there, it is extremely difficult to practice, Li Hetu only felt that there was no pain in the meridians around his body, and there was even more pain in the abdominal femur dantian. Cultivators, except when they are fighting with life and death with others, will exhaust all the internal strength of their bodies without reservation. In addition, no one would want to experience the pain of this dantian as if it were broken. After the internal strength is exhausted, not to mention the hammer, it is extremely difficult to stand up, and if the enemy comes again, it is no different from the baby in swaddling clothes, and there is no room for resistance and parry.

However, Li Hetu's strength of will and determination of his mind are far beyond the reach of ordinary people, and if it were not for this, it would be impossible to cultivate this awkward and tedious fire resistance technique to such a realm. In his short life of several decades, he has encountered changes in human feelings, and the world is hot and cold, which is really inhumane. The circumstances of life have long tempered their minds as hard as a rock and are invincible.

Stunned, he got up, lifted the hammer, and struck on the greenstone that had not yet condensed, and the residual force of the shock was like a steel cone, piercing the depths of the spinal cord. It's a pity that after a few taps, the faintly liquefied surface condensed again.

Li Hetu was not discouraged, he sat on the spot, crossed his legs, closed his eyes, and sat up in this furnace room, carrying the heart trick of fire resistance, and feeling the re-accumulated true power operating around his body for several weeks, and the soreness of his whole body could be regarded as a slight attenuation.

I don't know how long it took, Li Hetu opened his eyes, it was dusk outside the house, and it was time to eat, and it took two hours for him to meditate, although most of his internal strength was restored, but this afternoon's kung fu, really busy with sword casting, was only the kung fu of a pillar and a half incense, a stick of incense liquefied the greenstone, and a half pillar of incense was calcined and cooled. If we compare this sword-forging thing to a project, the entry of this project is really worrying.

Li Hetu stood up, but the sequelae of the exhaustion of internal strength were still there, and his mind was dizzy again, and he slowed down, walked out of the door, and walked to the place where Li Canglan practiced in the back mountain forest.

"Five hundred and twelve, five hundred and thirteen" heard his son's voice from a distance, Li Hetu couldn't help but smile slightly, and then approached. I saw a small figure appear at the end of the forest, sweat has soaked the child's entire back, just to do the action of lifting, but every movement is still sonorous and powerful, no lazy meaning, sweat down the child's pink cheeks, with a slight shortness of breath, look at this posture, I am afraid that I have not rested all afternoon.

Li Canglan was still engrossed in practicing, not noticing his father's arrival at all. Li Hetu didn't mean to alarm the child at all, but just quietly looked at Canglan's note, his eyes were full of love and relief.

Although the child's movements are a little immature, whether it is the pace or even every detail, he follows the points he has instructed during the day, and he has only spoken once. What is talent, this is the most outstanding talent of kendo. What is even more commendable is this self-discipline and perseverance, even if the natural divine power, with his strict standards, he will split 10,000 horizontally and 10,000 vertically, and there will only be one tired word left.

Li Canglan was naturally very tired, he only felt that his two arms were like straw, and his two legs were like sifting chaff, if he didn't try his best to hold back, he was afraid that he would have to shake twice from time to time. But he wanted to lower the standard of his movements, perfunctory, and hastily make a way to pass the times, but he was absolutely unwilling, and Li Canglan couldn't say a reason, he just felt that learning swords should be like this.

The father and son, one dancing and one watching, Gu was exhausted, but no one made an extra sound, and the afterglow of the setting sun sprinkled on the hillside, slowly elongating the figures of the two. The birds in the forest suddenly fluttered and flew in unison, flying towards the crimson sunset.

But it was Liu Lingyu who came up the mountain wrapped in an apron, the footsteps were near, Li Canglan suddenly looked back, but not far behind him was his father, who had been here for an unknown amount of time, and the two looked at each other and smiled. Liu Lingyu looked at the father and son who were standing in place stupidly, and couldn't help but laugh from the bottom of her heart.

"It's good to eat, and when it's time to eat, I'm still running around, two of them are not serious. ”

The setting sun surrounded the three figures and slowly walked down the mountain.

How good it would be if life stayed forever in this long silhouette.
