The power of the Azure Heart was too strong. Both Fang Zhentian and Feng Zhe could only slowly refine and penetrate the little bit of flame aura within their defensive shields. As for the outside situation, neither of them had the strength to investigate.

So, when Mo Wuji joined them and began to refine the Azure Heart, Fang Zhentian and Feng Zhe were completely unaware.

As soon as Mo Wuji started refining, he knew he had made the right choice. His Immortal Mortal Technique refined the Azure Heart like boiling a frog in warm water, without any abruptness. The Immortal Mortal Technique guided the Azure Heart to slowly circulate along the meridians, and each cycle took away a trace of the azure flame aura, which, after being refined, became Mo Wuji's own.

Initially, Mo Wuji could still feel the torment of ice and heat intertwining. Later, he could no longer feel any torment. The speed at which the Immortal Mortal Technique drove the azure aura also became faster and faster, which meant that his refining speed was also getting faster and faster.

As time passed, a large mass of azure flame aura had gathered in his body, all of which was the Azure Heart flame aura that he had completely refined. And the azure aura outside was still being constantly swallowed by the Immortal Mortal Technique, slowly grinding away its wildness and integrating it into his body.

The Immortal Mortal Technique was originally the most ordinary cultivation technique, or rather, it was originally cultivated from the most basic level. Unlike other cultivation techniques, this technique was too ordinary. When refining the azure flames on the periphery of the Azure Heart, it would not cause any stimulation to the azure flames.

At the same time, Fang Zhentian and Feng Zhe's refining was much more high-profile. From the surface level, their cultivation techniques were far stronger than the most ordinary Immortal Mortal Technique. The refining process was not as quiet as the Immortal Mortal Technique. As the amount of azure flames they refined increased, the temperature around them also became stronger and stronger.

If Mo Wuji hadn't joined them, the two of them might have been able to persevere for several days. It was not impossible for one of them to truly refine the Azure Heart in the end.

But Mo Wuji had joined them, and his refining speed alone was stronger than the combined refining speed of Fang Zhentian and Feng Zhe. The speed at which the azure flames on the periphery of the Azure Heart were refined increased exponentially.

Another hour passed, and the emerald light shield cast down by the jade flute above Fang Zhentian's head began to dim slowly. At the same time, the gaps in Feng Zhe's protective sword array also became larger and larger.

"Pfft!" When a larger gap was finally torn in Fang Zhentian's green light shield, Fang Zhentian could no longer hold on and spat out a mouthful of blood essence.

Without even looking at Feng Zhe, his body turned into a black streak and instantly rushed out.

Almost at the same time as Fang Zhentian rushed out, a ball of azure flames swept over, taking away all of Feng Zhe's clothes and hair. Feng Zhe didn't even bother with the sword array and similarly transformed into a shadow, fleeing from the azure flames.

Both of them were True God realm experts, and their retreat speed was extremely fast.

Fang Zhentian saw Feng Zhe, and Feng Zhe also saw Fang Zhentian. The two of them had already collided once when they came to seize the Azure Heart. Fortunately, their methods were basically the same, which was to guide the Azure Heart to several miles away and then slowly refine it.

Now that they had both failed, they seemed to have agreed, each going in a different direction, and quickly rushed out of the Lost Heaven Ruins.

This kind of thing could only be understood implicitly, not explicitly. For both of them, refining the Azure Heart was not impossible. As long as they found a stronger defensive shield, perhaps one day they could truly refine the Azure Heart.

With Feng Zhe and Fang Zhentian leaving, Mo Wuji's pressure suddenly increased. The temperature of the surrounding azure flames was also getting higher and higher, and half of the hill where he was located had been melted away by the azure flames.

Mo Wuji didn't know that Fang Zhentian and Feng Zhe had failed and retreated. After the surrounding temperature rose, he subconsciously began to reverse his self-created technique, and ice-coldness seeped out from his meridians. As the ice-coldness became stronger and stronger, a thin layer of mist formed on his body surface.

However, as soon as these mists appeared, they would be burned away by the azure flames.

As Mo Wuji refined more and more azure flames, the light azure aura surrounding his body became much deeper. At this moment, Mo Wuji's skin began to be burned away, and an aura of death enveloped Mo Wuji.

Even though Mo Wuji didn't open his eyes, he knew that if he didn't take action, he might be burned to death here.

Feeling the large amount of azure flame aura in his body that he had already refined, Mo Wuji was very unwilling. Once he retreated, these refined azure auras would directly escape and disappear.

Cultivation was originally a life-and-death struggle. When he came to refine the Azure Heart, he had almost died once. Now that he had already started refining, he would definitely regret it in the future if he retreated. Mo Wuji had a premonition that once he retreated, this Azure Heart would no longer be his.

Even if Fang Zhentian and Feng Zhe failed to refine the Azure Heart this time, they would find a better way and then continue to refine the Azure Heart.

Thinking of this, Mo Wuji gritted his teeth and tried again to increase the number of meridians reversing the technique he created.

Sure enough, when nearly thirty meridians were reversing their circulation, the ice-coldness seeping out from the meridians was even more terrifying.

The torment of tearing apart once again tore at Mo Wuji's body. Mo Wuji trembled all over, but he still frantically refined the Azure Heart flame aura.

After only half an incense stick of time, Mo Wuji felt an extreme heat sweep over the top of his head. Immediately, he knew that his hair and scalp had been completely swept away by the azure flames, and the temperature of the surrounding azure flames increased once again.

Mo Wuji sighed inwardly. It wasn't that he wasn't working hard, but that he really couldn't hold on any longer. The ice-coldness seeping out from his meridians and the temperature of the azure flames outside were not as simple as one minus one equals zero. The most important thing was that his physical body couldn't hold on. If he persisted, he would definitely collapse.

The weakest link now was not anything else, but his physical strength.

Mo Wuji wanted to stand up and retreat, but immediately realized that it was completely beyond his control at this moment. He couldn't leave at all. His strength was less than one ten-thousandth of what it was originally. How could he break through this terrifying flame?

Another piece of azure flame pounced over. Mo Wuji gritted his teeth and directly guided a trace of flame to start reversing its circulation in the same way as his reversed technique.

A trace of flame penetrated into Mo Wuji's meridians and instantly fused with the ice-coldness in the meridians. A lazy feeling came over him, and Mo Wuji was ecstatic.

Initially, he reversed his self-created technique to generate ice-coldness to offset the temperature of the azure flames outside, and then he took the opportunity to circulate the Immortal Mortal Technique to refine the azure flames on the periphery of the Azure Heart.

Now he was directly taking this azure flame with the spiritual energy to reverse its circulation, and he didn't expect that this would not only make the refining speed faster, but he would also no longer suffer from that terrifying cold and heat torment.

At this moment, he was only circulating about thirty meridians in reverse, and it already had this effect. Once all one hundred and two meridians were reversed, how heaven-defying would it be?

Suppressing the ecstasy in his heart, Mo Wuji began to slowly increase the number of reversed meridians. Each time he increased the number of meridians circulating in reverse, he would bring a trace of azure flame in to refine.
