This was the essence of the Great Blood Coagulation Art: Blood Refinement.

The Blood Solidification Realm believed that the blood essence of human cultivators was hidden within the bodies of martial arts cultivators and was distributed throughout the body.

Therefore, if one wanted to use the blood essence from a martial cultivator to cultivate, they would need to completely condense the blood essence around their body. In the end, they would need to condense it into a drop, or even several drops of blood essence.

After that, he refined this blood essence into Qi. This Qi was the ultimate essence of the Great Art of Blood Solidification, and could provide endless power to cultivators. This power was a hundred times more pure than the purest Qi in this world.

However, this method was only the most primitive method of using the Blood Solidification Realm. After all, the Blood Devil Sect treated all human martial arts as fish and slaughtered human martial artists. However, Lin Tian naturally wouldn't follow the Great Blood Solidification Realm to kill human martial artists.

After all, it was impossible for him to kill all of the innocent and kill all of the humans.

That was why he had used the Ancient Dragon Symbol to help him rededuce the Great Blood Coagulation Technique.

However, right now, Lin Tian had thoroughly understood the essence of the Great Blood Clotting Technique.

As the saying goes: never leave the sect. Lin Tian passed the deduction of the Immemorial Dragon Talisman and quickly grasped the cultivation method and trick of the Blood Solidification Realm.

The most important part of this cultivation technique was naturally the cultivation method. The cultivation method was quite simple, and after Lin Tian comprehended it, he experimented this cultivation technique on the greater demon in front of him.

This great demon was a third level third grade demonic beast. Its strength was comparable to a third level Jindan Stage human cultivator.

As a result, his Qi and blood were extremely vigorous, which was the perfect time for Lin Tian to test the power of the Great Blood Coagulation Art.

After that abnormally pure Qi was devoured by Lin Tian, Lin Tian felt that the incomparably pure energy contained within the Qi was almost comparable to the effects of several thousand spirit stones.

This made Lin Tian happy. To Lin Tian, what he lacked the most at the current stage was naturally resources. Spirit stones were always the key, and this time, it was Hua Ruyi who gave him a lot of spirit stones.

Especially since Lin Tian had currently cultivated the body of a dragon, his strength required an endless amount of resources.

It had to be known that when a dragon grew up, they would often have endless resources. However, because the dragon race was incomparably large, they had countless treasures and resources. Thus, they did not need to worry about the consumption of resources.

But Lin Tian was completely poor. From the beginning until now, Lin Tian needed to rely on himself for everything.

He needed to solve the problem of resources for himself. Of course, this was also the biggest problem for Lin Tian.

Previously, Lin Tian still didn't know how to solve the biggest problem with the resources, but now, with the Great Blood Clotting Technique, he didn't need to worry about anything.

With the Great Art of Blood Solidification, Lin Tian could utilize all the resources available to him. Demonic beasts, Berserkers, these resources could be said to be limitless.

As long as he could hunt for the existence of the Demonic Barbarian, Lin Tian's strength would naturally rapidly increase.

The Great Blood Coagulation Technique, this was basically giving away carbon in the snow.

Just as Lin Tian was celebrating about getting the Great Blood Solidification Technique, not too far away he saw Gu Qingyuan and the king with cold glints on their faces.

Especially Gu Qingyuan, who was currently staring fixedly at Lin Tian.

"This kid really cultivates that Blood Demon Sect's cultivation technique?" Gu Qingyuan was a bit worried. The two of them had guessed it earlier. Since Lin Tian obtained the cultivation technique from the bone flute, he naturally wouldn't let it go and would definitely cultivate.

Sure enough, the first thing this kid did when he came to Sky City was to practice that devil art …

Gu Qingyuan was at a loss for words, but he didn't go up to stop him. If this kid really cultivated to the point of massacring humans to cultivate his cultivation technique, Gu Qingyuan would not hesitate and directly kill Lin Tian as if he was a beast of the Blood Demon Sect!

This was Gu Qingyuan's bottom line. Similarly, this kind of method was also how he taught his disciples.

Back then, Xiao Yunhai had been bewitched by the previous generation's Holy Maiden, and had even committed a heinous crime. However, Xiao Yunhai had never fallen into the demonic path, and this was also the most important reason why Gu Qingyuan had not acted.

If the Xiao Yunhai back then had fallen into the demonic way, Gu Qingyuan would not hesitate to kill him.

As long as they didn't cross Gu Qingyuan's bottom line, Gu Qingyuan would still be very protective of him. Even if Xiao Yunhai committed a grave mistake, Gu Qingyuan wouldn't pursue the matter.

Currently, Gu Qingyuan naturally had the same attitude towards Lin Tian.

Of course, it was also because they had followed Lin Tian all the way here and saw that Lin Tian only used the greater demon to conduct experiments and did not kill humans. If they saw Lin Tian kill humans, the two of them would not hesitate to capture him …

Lin Tian naturally didn't know what Gu Qing Yuan and the king would think. He already knew in his heart that it was impossible for Lin Tian to kill innocent humans. This was different from his heart of martial arts.

This greater demon was also trying to test out the might of this Great Blood Coagulation Art.

Now that he had finished experimenting, Lin Tian's heart was filled with excitement. If this Great Blood Coagulation Technique could also be used on the Demonic Barbarian, then he would have earned it. In front of Sky City, the beast tide had just ended and the beasts on the ground were all ownerless.

Thinking of this, Lin Tian immediately no longer hesitated and began to madly move.

At this moment, the night was gradually getting darker. After a day of great battle, the students of the North, South, East, West, and North Academies were all extremely exhausted. At this moment, they had already gone to rest.

The demon beast horde continued for a few days, and Sky City's guards were also extremely tense during these few days. At this moment, the danger to the demon beast horde had been resolved, so Sky City's security was at its most relaxed.

Moreover, after the monster tide ended, they didn't have time to bring all the dead demon beasts back to the city. At this moment, all of the demon beasts were lying on the outside, giving Lin Tian a chance.

Those Monstrous Beasts were all treasures. Naturally, they were all taken away by the Sky City, and at the end, they were exchanged for resources. Some of them were left behind by themselves, and a large portion were given to the Azure Province Academy.

The students of the Azure Province were divided according to the number of students they hunted. In the end, these resources were still used to the fullest extent and returned to the students of the various academies.

Thus, these demon beasts were actually the public property. At this time, Lin Tian had already taken advantage of the public property.

With no time to think, Lin Tian immediately began to move quickly.

The main force of this beast tide was still a Rank 1 Demonic Beast. It was equivalent to the strength of a human cultivator, Qi Disciple stage, and Qi Hai stage.

Lin Tian didn't plan on using this type of demon beast. On one hand, its level was too low and it wasn't as useful as those greater demons to Lin Tian.

Also, there were too many of these monsters. Even if Lin Tian did not sleep at night, he would still not be able to completely refine them. After all, using the Blood Solidification Realm required soul force and time.

Thus, Lin Tian focused on selecting high level demon beasts, which were also Greater Demons at the third stage.

Previously, there were more than a hundred Rank 3 Demonic Beasts that were protecting the monster king. Lin Tian could only take care of them in one night. That was already not bad.

With a target, Lin Tian moved abnormally quickly.

One by one, the greater demons' corpses were quickly taken by Lin Tian into the stone tablet space that he obtained earlier.

Not long after, Lin Tian finished collecting everything. Then in the darkness, Lin Tian's figure disappeared in front of the north gate of the Sky City.
