The immortal energy condensed in those threads slowly entered Fei's body through the suction of his Silver Spiritual Roots. This energy passed through his meridian and entered his dantian. He was already at the peak of the Houtian Realm. Till now, everything that happened in his body was based on Su Ling.

His golden core, fire law, spiritual sense, blood condensation, muscles, and skin refinement, and bone forging, everything was done based on Su Ling's body. Fortunately, her cultivation was already top-level, so he didn't get into any kind of problem.

As for Xiantian Realm, he needs to condense true energy liquid from true energy. This is just like his spiritual liquid, except in higher form. Normally with his dantian condition, he might take years to fill it with true energy liquid with the help of normal energy.

But with immortal energy, he can condense true energy liquid faster. The immortal energy entered his dantian and his Ancient Heavenly God Force Art started working. It suppressed these energies, and condensed immortal energy into immortal energy liquid.

Fei knew what he was doing, so he didn't hesitate to create drops of immortal energy liquid. When ten drops of immortal energy liquid were formed, Fei used his Martial Spirits at their full power. His dantian was completely compatible with Ancient Heavenly God Force Art, constantly using immortal energy liquid to form essence in his body.

Actually, this essence is the reason which increases his cultivation, but true energy liquid is also necessary, so it was letting these immortal energy liquid drops convert into true energy liquid drops. Of course, from a certain perspective, immortal energy liquid will be better than true energy liquid so why convert it, because he can't use immortal energy in his martial arts.

But his cultivation was increasing based on essence refined from the immortal energy liquid. Because it will take a long time to refine true energy liquid, at least longer than immortal energy liquid. When the first drop was converted into the true energy liquid, there were large numbers of true energy liquid drops flowing out of his Martial Spirit.

When he used his spiritual sense to count it, he found there were a thousand drops. He was startled because he thought at least ten thousand true energy liquid drops would be created. But suddenly he remembered, a large part of these liquids' energy has been transformed into essence.

It took three hours just to convert a single drop of immortal energy liquid. At the same time, his cultivation was also rapidly increasing. He was getting closer, and closer to the Xiantian Realm. After fifteen hours, five drops of immortal energy liquid was converted into true energy liquid.

At this moment, his body erupts true energy from his body. At this moment, his whole body including the core part such as cells was washed with the flood of true energy. At this moment, he finally entered the Xiantian Realm.

But he didn't stop there because he has no reason to do so. His body was already very strong, his foundation was formed based on Dao Body. Yep, currently, his body foundation was based on Dao Body.

It was his luck to absorb Su Ling's dao energy to cultivate his Dao Body. His Dao Body is completely different than other bodies because Dao Body is supposed to be the most versatile body.

Yep, not just defense or offense or foundation or whole body, everything was improved. This was the best aspect of Dao Body. So he wasn't worried about his cultivation. He rapidly improved his cultivation with the help of immortal energy.

Within the next five days, he filled his dantian with true energy liquid also reached the third stage of the Xiantian Realm. But at this moment, not even a single thread of immortal energy was consumed.

Now, for the next stage, he began to condense the true energy core with the help of true energy liquid. The bigger the core, the more energy will it store. So for the next fifteen days, Fei continued to form the biggest true energy core inside his dantian.

Finally, after ten days, he condensed a true energy core in nine miles of diameter with the help of a single thread of immortal energy. After this, his cultivation also reached the sixth stage of the Xiantian Realm.

Fifteen days have already passed, Fei was continuously cultivating with determination in his eyes. At least, he wanted to reach the peak of Xiantian Realm before going out of the next trial. He also sensed his Ancient Heavenly God Force Art, wanting to breakthrough.

But he also understands the horror of energy consumption to form a soul. Previously, it took a large amount of Buddha energy to form his first soul. Now according to the Ancient Heavenly God Force Art, it would take double the amount of energy to condense his second soul.

But he doesn't want to breakthrough now; at least his goal is to cultivate to the peak of the Xiantian Realm before entering the second stage of Ancient Heavenly God Force Art. He knows the immortal energy is the only way to cultivate faster with his current dantian condition, otherwise, he might take a year to cultivate through one or two stages.

Till now, everyone time he has consumed normal energy or spiritual rank energy, he has barely crossed two or three realms. Even when the energy is very dense, so he doesn't want to waste this opportunity. Of course, he can still get energy after passing the second test; he still believes upgrading now is the best choice.

The final stage was the True Energy Domain Condensation Stage. Here, he needs to form a domain of his true energy. Currently, his true energy can be converted to any of nine elements from fire, water, wind, metal, earth, light, darkness, thunder, and ice.

So he can form a domain of any elements he wants. Currently, he was stuck on which to use. Of course, for him, the five elements domain is the best choice, especially with his Martial Spirit. But the other four elements are also much overpowered.

When he was in dilemma, his Eternal Will opened its eyes. It was still tried, but whenever Fei is in confusion, it will help. Just like the previous times. The Eternal Will moved his lips and recites few chants, then the next moment his Ancient Heavenly God Force Art starting running on its own.

This movement made Fei startled, and as he observed he found his Will wanting to make Ancient Heavenly God Force Art breakthrough. This caused Fei to sink into deep thought; finally, he decided to believe in his Will.

He ran Ancient Heavenly God Force Art at rapid speed, and immortal energy gathered at his sea of consciousness. All of his meridians were activated, and they were transferring immortal energy inside his sea of consciousness, where a certain figure was begin created. This figure was none other than his second soul.

His second soul was getting formed from the immortal energy which was completely different from his first soul formed with the help of Buddha Energy. Surely, this soul was completely different from his Buddha soul.

Because when it was getting formed, it was sucking endless vitality from the vitality seed. Fei was speechless over this action but he didn't stop it. Slowly, his second soul took two days to complete. This soul was the same as Fei, no different even skin tone, hair color, breath, everything was the same.

At this moment, he found an extra memory in his brain but just when he was going to read it, a strange thing occurred in his body. His Five Elements Inextinguishable Body Art as well as Five Elements Devouring Physique was activated.

Not only was that but his spiritual root constantly spreading all nine elements energy into his body. This made his dantian empty very soon, but once again it was filled with the spiritual liquid at the bottom of his dantian.

During his previous cultivation, he formed lots of spiritual liquid in his dantian. These can be a backup for him; he also filled his second mini dantian with true energy liquid. But that process didn't stop, and his body was constantly merging Five Elements Devouring Physique with nine elements, and strange energy from his meridians.

In his sea of consciousness, contents of Five Element Inextinguishable Body Art were disappearing. At this same time, he screamed in pain due to a massive change in his body. His blood veins get broken into pieces due to a large amount of energy, the same for his meridians.

"Ahhhhhhhh"

His physique was also destroyed, while Fei's consciousness passed out. Although he passed out, his body was constantly changing; those destroyed veins and meridian were getting repaired with Wood Body Repair, and extra vitality.

Su Ling also saw his body bursting, as the pool of blood spill near him. This wasn't truly something Fei could handle. Even Su Ling was about to pass out when she saw his outer body explode. Fortunately, his body was repairing itself every soon.

At this moment, his body was constantly devouring those threads of immortal energy. And finally, when it turned silent, only one thread of immortal energy was left. At the same time, his body was repaired completely though he was still unconscious.

After his body was repaired, everything turned silent all those meridians were running quietly. A major change occurred in his body, and after a day when Fei woke up, the first thing he saw was his stats and new change. At first, he didn't get much happy because his body was burning in pain but soon happiness flashes in his eyes when he saw a major change in his body.
