Wei Wuji couldn't help but feel a sense of pride for Fang Cai's control of ice and fire, and at the same time he was a little helpless.

With ice cubes condensed and then melted into snow water for bathing, he estimated that he might be the first to do so!

Anyway, there was no one else in the grotto except him, Wei Wuji simply stood naked in front of the deep pit in the center of the grotto, he quietly looked at the churning magma under his feet, felt the bursts of heat emanating from it, he felt that he could take the second step.

This is also what he had thought about before he came here after he left to cold them.

The first step was to use wild fruits to improve his strength, and now he has completed it, and the effect is surprisingly good, completely exceeding his expectations.

And the second step, as early as the first time he came to the underground grotto, and saw the magma in the deep pit, he already wanted to do it.

The sword light flashed, and the sword embryo made of colorful meteorite iron and cold ice iron essence gold had appeared in his hand.

The sword embryo had not been kept in the divine consciousness space by him for a long time, and the whole sword still looked pitted and very ugly.

As soon as he let go of his hand, the blade had slipped into the lava in the pit beneath his feet.

Wei Wuji sat cross-legged on the edge of the pit, using his divine sense and the natal ice qi contained in the sword embryo as a guide, combined with the terrifying fire in the underground magma, constantly refining the sword embryo.

He originally wanted to temper it with his natal fire, but thinking of the terrifying temperature of the Immortal Cangyan, he felt that it was better not to try, if he didn't control it, if the colorful sword embryo was melted by the Immortal Cangyan, it would really be worth the loss.

And the churning magma underground, and the temperature of the fire in it, in his judgment, should be just right!

In the underground magma, the colorful sword embryo did not sink too deep into the magma, under the traction and control of Wei Wuji's divine sense, it was like a colorful swimming fish, constantly swimming and shuttling in the magma, looking a little cheerful.

With a snort, with the cold air that continued to seep out of the natal ice qi in the colorful sword embryo, it constantly collided with the heat in the magma, and on the sword embryo, a piece of stone skin like rust peeled off, revealing the sword body that was as smooth as a mirror inside!

Wei Wuji couldn't help but secretly rejoice, he continued to control the output of the natal ice qi in the sword embryo, and the collision with the magma became more and more intense.

The speed at which the stone skin peeled off was accelerating little by little, and as the pitted stone skin on the sword embryo peeled off more and more, revealing more of the sword body, Wei Wuji felt that the connection between himself and the colorful sword embryo became closer, and the feeling of water and milk blending became stronger and stronger!

With the continuous vibration of the sword body, a trace of cold air came out from the sword body, and the magma around it sneered, and the white smoke continued to rise from the magma, and the entire pit seemed a little foggy.

"Hey, it's still too simple!"

Wei Wuji let out a long sigh, although the heat in the magma was strong, there was still a limit, and the firepower was not concentrated enough.

After the colorful sword embryo was tempered to a sword body that was close to two feet, he clearly felt that unless he immersed the sword embryo in the magma for a long time, it would be difficult for the magma here to have the slightest effect on his sword embryo.

The second step seems to be a failure, Wei Wuji smiled bitterly and shook his head, it seems that there are really gains and losses!

The first step was more successful than he could have imagined, and the second step was only a little more than half a step before it was declared a failure.

"How daring!"

Suddenly, Wei Wuji shouted, only to see that in the underground magma, a fiery red monster fish about several zhang long suddenly burst out of the magma, it folded in the air, and directly grabbed the colorful sword embryo in one bite, and then quickly sank towards the depths of the magma.

Wei Wuji's face couldn't help but change drastically, he urged his divine consciousness again and again, but no matter how he urged it, that divine consciousness and his natal ice qi seemed to be blocked by an invisible force, he could only barely sense it, but could not make the slightest other action.

With a "bang", Wei Wuji turned into a purple flame and instantly threw himself into the underground magma.

Thanks to his indestructible cangyan, otherwise he really wouldn't dare to enter this underground magma, although the underground magma is hot, but compared with the immortal cangyan of the Shenhuang clan, which is proud of all races, it is still much worse, and it can't do him any harm.

The only trouble is the fire poison in the magma, but fortunately, the ice and fire disc in his body carries infinite immortal power and immortal power, and a little fire poison can't have much impact on him.

After Wei Wuji's incarnation of Immortal Cangyan sank into the magma, the fiery red strange fish had disappeared without a trace, but fortunately, the sense between him and his own divine consciousness was already there, and the purple light flashed, and the immortal Cangyan moved, and he had quickly chased in the direction where the fiery red strange fish had fled.

No matter what, the colorful sword embryo must not be lost, it is one of his natal weapons, and there is not only a wisp of his natal ice qi in it, but also a piece of his divine sense.

Although with his current realm cultivation, as long as his ontological divine consciousness was not damaged too much, even if he lost that divine consciousness and natal ice qi, it would not have much impact on him.

But the colorful meteorite is rare, and it was given to him by the Venerable Purple Thunder and Xiaohuan, and Sun Tong worked hard to create it with great vitality injury, which must not be lost, otherwise how can he be worthy of them?

As Wei Wuji continued to go deeper, the heat in the underground magma began to become more and more intense, but fortunately, the Immortal Cangyan was indeed strong enough, and he hadn't felt too much pressure yet.

On the contrary, the fire energy in the magma was absorbed a lot by the Immortal Cangyan around him, and the Immortal Cangyan seemed to have become a little richer, which made him feel a little more depressed.

Following the faint sense of his divine sense, Wei Wuji swam swiftly forward, he already knew what the strange fish that had taken away his natal sword embryo was.

The syrup fish, a kind of strange fish that lives in the underground magma, does not like to be in groups, and only likes to act alone, but the largest syrup fish that I have heard of before is only three feet in size, which is like the previous one, it is more than a few feet long, and I don't know how long it has survived in this underground magma, and it has grown to such a point.

With that hurried glance just now, he had roughly judged that the strength of that syrup fish should be comparable to that of a mid-level powerhouse of the Terran fetal breath.

The magma was still hot, and Wei Wuji didn't know how far he had chased it, he just felt that if it was above the ground, he would have chased it for at least dozens of miles.

The syrup fish was still far away from him, and Wei Wuji couldn't help but feel a trace of anxiety on his face, although after entering the fetal breath realm, he could hold out for a long time without relying on air, but once the time was too long and the distance was too far, if he regained the natal sword embryo, but couldn't find his way back, it would be really a big trouble, and he couldn't live in the magma like that syrup fish!

Just when Wei Wuji was not only starting to get agitated, but also a little angry, he finally sensed that the speed of the syrup fish in front of him had slowed down, and its direction was no longer downward, but began to go up.

Wei Wuji couldn't help but secretly breathe a sigh of relief, and with a flash of purple light, his forward speed suddenly increased by a few points.

Coming up, Wei Wou-Ki felt that he was getting closer and closer to the natal sword embryo.

Ahead, a crack several zhang wide appeared in front of Wei Wuji's eyes, and as soon as the immortal flame moved, he had already passed through the crack.

With a "whew", Wei Wuji came out of the crack, and his gaze swept away, and he couldn't help but be stunned, he didn't think that behind the crack was actually a grotto.

Wei Wouji levitated, looking at the magma surging under his feet, and the stalactite pillars hanging down from the top of the grotto, until he was down-to-earth, he let out a long breath, it still felt good on the ground.

The grotto is not large, only ten zhang square, and a deep passage extends to the front.

Traveling along that passage, what Wei Wuji couldn't understand was that he didn't say that the syrup fish had always lived in magma, and how did it get to the surface?

Wei Wuji shook his head and pressed this doubt down, no matter what, he would be able to see it in a while anyway, and when the time came, everything would be understood.

In the divine sense, the natal sword embryo was in front of him, and Wei Wuji strode forward along the passage.

Although that syrup fish has a mid-level cultivation of fetal breath, but now that he has cultivated to a great advancement, he doesn't care about it, when he transforms into a mid-level, he has been able to kill the beginner-level demon generals among the hundred clans, not to mention that now he has also broken through the fetal breath realm, he believes that even in the face of high-level demon generals, he can be completely fearless.
