The Northern Courtyard had built a separate room for the older students.

There were rows upon rows of rooms arranged according to the order of A, B, C, and D.

A room with the number A number was naturally the best.

Moreover, there was a suite in the room, and it was not just one room. It would not be a problem for Lin Tian and the other two to stay there.

Lin Tian didn't say much and directly went to his room. He sat cross-legged and began cultivating.

He had been stuck at the seventh level of the Qi Hai realm for quite some time now.

After passing the Green Province's exam grounds and the arena battle, Lin Tian experienced one battle after another.

He had long since reached the critical point, but Lin Tian intentionally suppressed his own cultivation speed, so he had never broken through.

But now, the situation had changed. It was time to break through to a higher realm.

He took out everything in his storage ring. In his storage ring, besides spirit stones, there were also spirit stones, the spirit stones he had sold those Rank Three demon beasts in the Clear Pavilion, as well as the spirit stones that Hua Ruyi had given him before she left. Right now, there were over ten thousand high grade spirit stones and several dozen low grade spirit crystals in Lin Tian's hand.

These would become the most important things he could rely on to break through.

He silently circulated his whirlpool of Dantian and started to devour the spiritual power within the spiritual stone.

In just a few moments, the Spirit Stones were quickly reduced to dust at a speed visible to the naked eye. The Spiritual Energy was like a small stream as it was swallowed by Lin Tian into his body, turning into pure Essence Qi that he stored in his Dantian.

At the same time, his whirlpool of Dantian was also undergoing a slight change.

The cultivation realms of the Heavenly Dragon Continent's mountains were divided into four major realms: Qi Cultivation, Qi Sea, Jindan, and Xinghe.

Qi Cultivation was the process of sensing and absorbing the Spiritual Qi of Heaven and Earth, transforming it into the Yuan Qi that a warrior needed. Once the Yuan Qi was comprehended, one would be able to reach the Mortal Realm.

When his dantian stored enough Essence, it would be able to form a Qi Sea in his dantian, which was also known as the Essence Sea.

If the Essence Sea was not exhausted, it could provide endless amounts of Essence support to Martial Cultivators.

When the primeval sea reaches a certain degree, it can form the aurous core.

At this moment, the elemental energy within a cultivator's body would be converted into a substantial amount of energy — elemental energy.

Elemental energy was much more powerful than elemental energy, and it was also much more powerful.

Therefore, after reaching the Aurous Core stage, the strength and lifespan of a martial cultivator would greatly increase.

It could be said that after reaching the Aurous Core Stage, martial arts cultivators could be considered as having the ability to settle down on the path of martial arts. They could also be considered as experts.

To form the golden core, one needed to be at least at the Qi Hai realm!

The Qi Sea was huge enough to condense the Yuan Qi. It would be more convenient to condense the aurous core. Moreover, an expert who broke through to the Aurous Core stage would also be much stronger.

In other words, the more solid the foundation, the easier the road ahead would be.

What Lin Tian needed to do now was to continuously fill his own aura sea.

The spirit stones quickly disappeared and turned into pure Yuan Power that was stored in Lin Tian's body. It slowly accumulated in the Dan Tian whirlpool, causing the Qi Sea in the Dan Tian whirlpool to continuously expand and expand.

However, the process was extremely slow because Lin Tian's dantian wasn't a human's dantian, but a dragon's dantian.

The dragon race's body was incomparably large, and the dragon race cultivated their 'essence, energy, divine, and body' together. This was also why Lin Tian had never practiced the body forging technique alone, but the strength of his body was no weaker than a martial cultivator who had started to temper his own body since he was young. As he continuously cultivated, his soul, vitality, and body constantly grew stronger.

Because of this, the amount of Spiritual Energy he needed to break through far exceeded that of ordinary people.

Not long after, Lin Tian had already absorbed over a thousand high grade spirit stones. The Qi Sea in his dantian was also rapidly expanding, but during this process, he had no intentions of breaking through.

After an unknown amount of time, when the spirit stones in front of Lin Tian had turned into a thick pile of dust, Lin Tian finally stopped his cultivation. The spiritual energy around his body turned into many long dragons and crazily rushed into Lin Tian's body.

After a while, it went through the whirlpool's dantian and became Essence Qi. It stored it in Lin Tian's body again.

Not only that, the strands of spiritual energy even rushed into Lin Tian's Divine Palace and were absorbed by the Divine Palace's soul.

Inside the Divine Manor, Lin Tian's tiny soul was becoming more and more corporeal. The Ancient Dragon Rune on his forehead was also currently flashing with a strange light.

It was unknown how much time had passed after this change.

Lin Tian suddenly spat out a mouthful of white mist. His body seemed to be emitting a faint draconic roar.

"Moo!"

At this time, Lin Tian also opened his eyes. Within his eyes, a strange light suddenly flashed. His strength had increased greatly and his body suddenly shook. The filth on his body was also forced out of his body by Lin Tian, emitting an extremely fishy smell.

Lin Tian smiled slightly and said: "Eighth level of the Qi Hai realm … …"

He sat down cross-legged again and began to absorb the spirit stones in front of him. Just now, when he broke through to the first level, he had used almost three thousand high-grade spirit stones, but this was still not enough for Lin Tian. He had already reached the eighth level of the Qi Hai realm, and it was still far from enough.

It was also at this moment that the whirlpool in Lin Tian's dantian was also quietly changing.

The Qi Sea that was originally large to a certain extent, like a vast ocean, actually started to quietly condense again.

Lin Tian naturally knew what it was.

This was the sign that he was about to form the golden core.

The ninth level of the Qi Hai realm was about to condense the golden core … However, the golden core in his body was only an embryo, not a real golden core.

Once a true Jindan was formed, that meant that the person had become a Jindan Stage expert.

Lin Tian continued to devour the spirit stones in front of him. However, currently with the strange change in Lin Tian's body, the speed at which he devoured spirit stones had increased by a dozen times.

Spirit stones quickly turned into dust one by one, and the Spiritual Energy rushed into Lin Tian's body in an unending stream.

After a long time, the Qi Sea in the swirl's dantian completely compressed into the appearance of a golden core.

However, the current Jindan was too dim and its power was not too strong.

He could only rely on his spirit stones to continuously supply Spirit Stones to condense the aurous core.
