Cultivation is just so scientific!

Chapter 1391: Chapter 742: Forbidden Spirit

The gravity field of the Spirit Treasure ’Ten Thousand Sword Peak’ was released, and Li Yuanba felt a lightness on his body. Within this gravity field, Li Yuanba was the master and could control the pressure of the gravity field.

The gravity field of the steps overlapped with the gravity field of the ’Ten Thousand Sword Peak’. The Spirit Treasure-level ’Ten Thousand Sword Peak’, with its quality advantage, integrated into the gravity field of the steps and took over the control authority.

Of course, this control authority could only act within the range of Li Yuanba’s body and couldn’t achieve complete control.

But it was enough for him to make his body unaffected by gravity.

Step by step upwards, he couldn’t help but curse in his heart. How could a Nascent Soul Middle Stage Practitioner pass through here? Forget Nascent Soul Middle Stage Practitioners, even a Great Cultivator couldn’t withstand the increasingly strong gravity.

Fortunately, he had many means to deal with the trouble at hand.

Finally, he stepped onto the last stair. On the previous stair, he felt a warning from the Artifact Spirit of ’Ten Thousand Sword Peak.’ The gravity field controlled by the Spirit Treasure ’Ten Thousand Sword Peak’ was too strong, beyond the current tolerance of ’Ten Thousand Sword Peak.’

The strongest state of a Spirit Treasure requires the support of a cultivator, not a cultivator like the current Li Yuanba, but one at the Mahayana Realm.

Without the support of a cultivator, the power exerted by the Spirit Treasure ’Ten Thousand Sword Peak’ is also limited.

Fortunately, after stepping on the last stair, Li Yuanba learned from the Artifact Spirit that this stair had returned to normal gravity.

He saw a palace in front, the core of the entire Grotto Heaven.

He did not immediately explore the palace but looked down at the steps under his feet.

After he walked all the steps, a rule light flickered on a gravity gold brick connecting the steps, and the disappeared steps behind him reappeared.

He squatted down and focused on this gravity gold brick.

’Shenmutong’ activated, combined with his divine sense and the distant IBMz15, he began to examine this gravity gold brick repeatedly.

He had a feeling that this gravity gold brick was the reason for the steps’ increased gravity.

Sure enough, from this gravity gold brick, he vaguely sensed the Rule Power, and he was also sure that this was no ordinary gravity gold brick.

Although this gravity gold brick looked almost identical to other gold bricks, the others had no Rule Power and would not emit light before the steps appeared.

With a wave of his hand, the Spirit Treasure Xingyi Sword appeared. He mobilized his ’Po Xujianyi’ and began cutting the connecting parts around this gravity gold brick.

Though the adhesive materials used for the original construction were extremely sturdy, the builder Langcai Great Power probably never imagined that a Sword Cultivator would use ’Po Xujianyi’ to slice through.

Even using the Spirit Treasure Xingyi Sword, fortified with ’Po Xujianyi,’ it still took considerable time to extract this gravity gold brick. If one were to destroy it in this manner, it might take more than a hundred years.

In fact, the main reason he could cut out this gravity gold brick was the decline in energy within the Grotto Heaven; otherwise, the natural energy protection here would have made any disturbance impossible.

Li Yuanba looked at the gravity gold brick in his hand and attempted to insert a Master Recognition Technique spell. Once the Master Recognition Technique fused with the gravity gold brick, a connection formed between him and it.

This gravity gold brick was neither a magic artifact nor a Spirit Treasure but rather a unique formation core.

It was unknown how Langcai Great Power managed to refine the gravity gold brick into a formation core with gravity rules, which could activate the gravity rules within the gravity gold brick when paired with the appropriate formation.

Additionally, the material of this gravity gold brick had been assimilated by the Grotto Heaven. Though it appeared the same as other gold bricks, upon mastering it, he perceived its true material beneath the disguise of the grotto.

This material, which he had never seen before, felt somewhat like the core of a Grotto Heaven, naturally possessing Rule Power of gravity.

The gravity gold brick had little effect in the hands of other cultivators, having been forged into form by Langcai Great Power. Unless one surpassed Langcai Great Power in cultivation, it would be difficult to reforge the gravity gold brick.

To harness the gold brick’s capability, one needed the corresponding formation.

However, since the formation involved Rule Power of gravity, even an Array Master could not combine the formation with Rule Power.

But Li Yuanba was different. While walking on the steps, he was connected to IBMz15, recording all the various data from the steps.

By integrating the formation capabilities of his essence, Li Shiming, and the analysis and calculation capabilities of IBMz15, combined with the data collected on the steps, the possibility of redeveloping a formation was great.

Nevertheless, this did not concern the current Li Yuanba. He put away the gravity gold brick and turned his gaze toward the palace ahead.

He approached the palace very cautiously, as the dangers encountered earlier had greatly exceeded his expectations.

He indeed had many means, but if he encountered something he couldn’t handle, it could be a matter of life and death.

The palace emitted an ancient aura as he arrived at its entrance.

The wooden doors were inlaid with golden round nails, and most peculiarly, the wood used for the doors emanated a metal aura. This wood was actually of a metallic nature.

The Cultivation World had many amazing materials; he had seen bi-metallic wood, but pure metallic wood was something he was witnessing for the first time.

Its quality had reached fourth-grade top level, and if he could take down this door, it could be used to forge dozens of fourth-grade top flying swords.
