The better the cultivation technique, the more types of qi it can absorb at the same time.

Given the total amount of air remains constant, the more types of gases a device can absorb from the air, the higher the absorption efficiency and the more gases it can absorb during the same period.

The Chaos Art that Dong Tianyu practiced was like a high-powered vacuum cleaner that indiscriminately absorbed any and all forms of energy, and naturally, the cultivation efficiency was extremely high.

The reason his cultivation speed was initially gentle was not due to a problem with the cultivation technique; it was because Dong Tianyu wasn’t dedicating enough effort to his practice.

Unlike other cultivation systems, the path of cultivation has no limit on daily cultivation time. As long as the cultivator is willing, and the body can endure it, it is very common to have immersive cultivation sessions that last a month or even several years.

Normally, those at the Foundation Building Stage are still unable to abstain from grains, and only when one reaches the Golden Core Stage can they live off of the wind and dew—this is why it is often said: "Once the golden core is swallowed, my fate is my own, not heaven’s."

After reaching the Golden Core Stage, one is no longer constrained by the need for food, so even if trapped somewhere, they would not die of hunger.

When the need for food and water is lost, cultivators can live comfortably in the majority of environments for extended periods.

The energy in the air within the Cave was always many times higher than the outside world, after all, the Cave was hidden within chaos, constantly absorbing energy from its surroundings to improve itself.

The Way of the Golden Core, the Way of the Golden Core.

After being stuck at the peak of the Foundation Building Stage for a while, Dong Tianyu suddenly condensed his Golden Core during a dual cultivation session.

Dong Tianyu never expected that his first condensation of the Golden Core would occur under such circumstances.

As soon as the Golden Core formed, it immediately absorbed all the energy within his body and then, in an extremely brief moment, that energy burst forth from the Golden Core once more.

If the energy within his body was akin to an ocean before the Golden Core absorbed it, then the amount of energy it released was like a small stream, a gentle trickle.

Though there was much less energy in quantity, the quality underwent a transformation as vast as the difference between heaven and earth.

While Dong Tianyu was experiencing the changes from his breakthrough to the Golden Core Stage, Jasmine Anderson, who was dual cultivating with him, found his sudden cessation rather hard to deal with.

But looking at Dong Tianyu sitting motionless, Jasmine Anderson suddenly smiled. If the enemy didn’t move, then it was her turn. After all, in a battle between two, someone had to make the first move.

Because Dong Tianyu’s mind was immersed in the Golden Core, he didn’t stop Jasmine Anderson’s actions, but continued to experience the changes within himself.

By the time Dong Tianyu gained a preliminary understanding of the changes in the Golden Core Stage, Jasmine Anderson had long since left his side, leaving him alone on the bed.

Seeing his brother somewhat furious, Dong Tianyu used his Divine Sense to check the position of the other Canaries and, with a slight pull of his hand, he brought one Canary from her own room to his side.

Despite Dong Tianyu’s display of strength in the Golden Core Stage, such actions could only be displayed within the Cave, as Dong Tianyu was the master of the Cave.

To perform such an act in the outside world, unless Dong Tianyu achieved immortality, it would be difficult to replicate the action he just did.

Perhaps it was the excitement from just breaking through to the Golden Core Stage, but Dong Tianyu’s little brother was unusually spirited, calming down only after knocking out all opponents consecutively.

The Cleansing Spell that previously required a verbal incantation could now be successfully cast with just a thought.

As for the Art of Controlling Objects, which originally needed a spell to be cast on an object beforehand in order to control it, Dong Tianyu could now control any object within the range of his Divine Sense that didn’t contain spiritual rhymes with just his thoughts.

His Divine Sense now had not only its original abilities of detection and X-ray vision as auxiliary powers, but it also gained a special effect similar to telekinesis.

Mental intervention in reality.

For Dong Tianyu, who had reached the Golden Core Stage, this was no longer a difficult task. It was only after Dong Tianyu broke through to the Golden Core Stage that he truly understood how vast the gap was between it and the Foundation Building Stage.

Now, Dong Tianyu’s Divine Sense could cover an area several times larger than before, and the quality of the Spirit Power within his body had a fundamental difference in quality compared to the Foundation Building Stage, akin to the difference between iron and wood.

After trying out all the spells he knew, Dong Tianyu finally calmed his emotions, and then he began to re-enter the Hall of Longevity. He used the System to cultivate in an idle mode, guiding his first cultivation session in the Golden Core Stage with caution through the System’s idle training method.

Under the guidance of the System, Dong Tianyu completed a perfect cultivation session. Not only did he restore the upper limit of energy in his body that had been reduced due to refinement, but he also further increased the physical strength of Dong Tianyu’s body.

Having perfectly concluded his first cultivation session in the Golden Core Stage, Dong Tianyu left the Hall of Longevity.

This period of seclusive cultivation had caused Dong Tianyu to be somewhat out of touch with the outside world.

Although his parents had been well settled, and he had entrusted Robinson William to take care of them, Dong Tianyu still missed them after such a long time.

It truly confirmed the old saying, "In cultivation, there are no years." Dong Tianyu had not expected that he would spend such a long time in immersive cultivation.

Now that his Cultivation Level had reached the Golden Core Stage, there wasn’t much else to say; he had to first arrange the training of the Sword Control Technique.

After all, among the many who longed for cultivation in China, who wasn’t first attracted by the stylish Sword Flight?

After spending some Survival Points, Dong Tianyu obtained the Sword Control Technique - Thousand Sword Scripture from the Library Tower.

The name was domineering, and the effect was even more so. Dong Tianyu didn’t know if other versions of the Thousand Sword Scripture require the control of ten thousand physical swords, but the version he drew allowed him to transform the Spirit Power between heaven and earth into sword shadows when he cast it.

Putting aside other aspects, this ability to convert energy into a physical entity would have been considered a BUG-level power before the calamity.

It was like using a special instrument to convert carbon dioxide in the air into starch – an incredible feat at any time.

Of course, having just acquired the Thousand Sword Scripture, Dong Tianyu couldn’t achieve the feat of a thousand swords firing simultaneously. After initially mastering it, he only reached the level of Sword Flight. To materialize the ethereal sword shadows, he needed much more practice.

Dong Tianyu didn’t leave the Cave until he had mastered Sword Flight.

After leaving the Cave, Dong Tianyu immediately soared into the sky on his sword.

Although he had already mastered Sword Flight in the Cave, flying with his sword outside felt completely different from flying within it.

As Dong Tianyu circled above the sky, looking down upon the earth, a surge of boldness rushed to his brain, and he couldn’t help but let out a loud long howl in the sky.

And it was this howl that attracted several ancient creatures with the ability to fly.

Seeing these ancient creatures approaching, Dong Tianyu did not take action; instead, with just a thought, the wings on the backs of these flying ancient creatures were as if attacked, instantly folding in half.

After their wings broke, unlike in animations where there would be a delayed reaction before falling, these creatures quickly plummeted downwards. From this height, the chance of survival would definitely not exceed one percent.

This was not the result of Dong Tianyu using any special spells; it was simply the effect of his enhanced Divine Sense paired with the Art of Controlling Objects, as long as there was no innate power cultivated within the body and no materials with spiritual resonance on them.

With Dong Tianyu’s Divine Sense combined with the Art of Controlling Objects, it was easy to produce effects similar to telekinesis seen in movies and TV shows.

And this effect would only become stronger as Dong Tianyu’s Cultivation Level increased.

After dealing with the flying ancient creatures attracted by his howl, Dong Tianyu silently extended his Divine Sense in all directions.

Having reached the Golden Core Stage, Dong Tianyu’s range of Divine Sense had also increased several fold.
