Chapter 43 Development of the Diamond Lockdown Form

"Um……?"

"What did Danzo do to my cellular chakra?"

Inside the glass chamber of Laboratory Two, Li Yao felt the portion of his chakra that had been separated from him by Danzo being devoured.

A vast chakra, brimming with powerful life force, was devouring his chakra. His chakra was unable to resist and was quickly consumed.

Li Yao's consciousness, which was fused with chakra, quickly dissipated once the chakra was gone.

That chakra-devouring power was too strong!

If the Eight Trigrams Seal absorbing his chakra was merely like digging with a spoon on a shovel, then that massive chakra was like a giant excavator frantically digging.

That powerful devouring force was something that Li Yao's chakra couldn't resist at all.

"What should we do?"

Li Yao pondered.

If that chakra were to appear on him, he would be drained of his chakra and die. Even if he didn't die, without chakra, he would never be able to escape from here.

"Just a little bit more, just a little bit more."

Inside Li Yao's chakra points, he was fusing the chakra attributes of the points with those of the Eight Trigrams Sealing Technique, while simultaneously constructing and transforming the chain chakra form.

Six months ago, Li Yao, who had been trying every possible way to convert his chakra into strength, finally came up with a solution.

His most powerful ability right now is sealing chakra.

Both acupoint chakra and Bagua sealing technique chakra possess powerful sealing abilities to imprison and bind chakra.

He wants to make this sealing ability simpler and more powerful.

Generally speaking, sealing techniques require first using abilities to immobilize the enemy before the sealing formula can be released on them.

The process of releasing the sealing spell pattern cannot be interrupted. If the target moves violently, the sealing spell pattern will deviate, causing the sealing spell to fail or become unstable.

Therefore, sealing techniques are generally not used as a regular tactical choice when facing enemies.

However, one ninja clan has overcome the drawback of needing to immobilize the enemy before releasing sealing techniques.

That is the Uzumaki clan. Their sealing techniques have been developed to the point where they can be used as conventional weapons.

The most famous of them all is the Kong Lockdown.

By condensing the sealing chakra into a solid-like chakra chain through chakra shape transformation, the sealing technique can change between reality and illusion, and can ignore the limitations of whether the enemy is fixed or not. As long as it is inserted into the enemy's body or bound to the enemy, the enemy's chakra can be sealed.

The Vajra Sealing Technique is a sealing chain formed by the Vajra Sealing Technique's chakra through extreme chakra transformation.

It possesses a powerful sealing effect that would even immobilize a fully-formed Nine-Tails sealed inside Kushina's body.

Unlike the Eight Trigrams Seal that Minato later used, which couldn't completely suppress the Nine-Tails with sealing chakra, he could only focus on increasing the strength of the seal gate, leaving the Nine-Tails a small private room.

This shows that the Vajra Lockdown is already a very powerful technique, at least very suitable for the situation Li Yao is currently facing.

Therefore, Li Yao wanted to condense the chakra from the sealing techniques he had learned into the Vajra Chains.

Moreover, he is much more ambitious.

He wanted to combine the high binding properties of acupoint chakra with the restrictive properties of Bagua sealing technique chakra to create a new sealing technique chakra with powerful restrictive and binding properties on chakra.

Then, using this new sealing technique, chakra is condensed into the form of the Adamantine Sealing Technique.

Li Yao believed that this new sealing technique, the Vajra Lock formed by chakra condensation, would be able to instantly imprison the enemy's chakra flow.

After that, Li Yao continued to fuse the chakra attributes of acupoints and the chakra attributes of the Eight Trigrams Sealing, as well as develop the form of the Vajra Sealing Chakra.

Whether it's the fusion of the chakra attributes of acupoints and the chakra attributes of the Eight Trigrams Sealing Technique, or the development of the Adamantine Sealing Technique chakra form, it's not much different from developing a new ninjutsu for Li Yao.

Fortunately, his chakra perception ability is truly abnormal.

He took similar and related parts from the nature changes of acupoint chakra and Bagua sealing technique chakra, and conducted disassembly and fusion experiments, constantly experimenting and comparing them.

Six months later, Li Yao is just one step away from fusing the new sealing technique chakra, which is greater than the sum of its parts.

At the same time, the Chakra form of the Adamantine Sealing Technique is only a little short of being developed to its most stable state.

The Adamantine Sealing Chakra Form may appear to be just a chain formed by a "U" ring enclosing another ring, but it actually contains more complex form changes.

Just like the Rasengan, which may appear to be just a ball of chakra that is compressed and spinning at high speed, the overall rotation and compression is regular, and it is all compressing and rotating inward.

If the rotation is irregular, the chakra will be unstable and it will be impossible to form the Rasengan.

This can be seen from the second stage of Rasengan practice.

If a stable and continuous output of chakra cannot be achieved to form a stable state of rotation and compression, the water-filled balloon will break due to even the slightest fluctuation.

The same goes for the Vajra Lock. If it were simply to condense the form of chains, it would be easy; Li Yao could do it effortlessly.

However, such chakra chains are very fragile and break easily, making them completely incapable of binding a chakra monster like the Nine-Tails.

After all, in addition to its enormous chakra, the Nine-Tails also possesses the terrifying physical power to instantly carve a trench five or six meters deep in solid rock.

If the Vajra Seal isn't strong enough, it simply can't bind such a Nine-Tails.

Therefore, simply forming the form of the Vajra Lock is not enough; the most crucial step is to construct an internal structure that makes the Vajra Lock exceptionally robust.

At this stage, Li Yao didn't have the real Vajra Seal Chakra to perceive and observe; he could only rely on his own imagination to develop it.

What is the most durable material?

Many people would think of steel and diamonds.

But if we're talking about which chain is the strongest, least likely to break, and most capable of withstanding tension, then...

The image that instantly flashed through Li Yao's mind was of various modern steel cable bridges spanning the mountains and rivers of modern Guizhou.

Those steel cable structures that can support thousands or tens of thousands of tons of weight are definitely the best examples of chain strength.

Li Yao's "King Kong Lockdown" was developed and researched by imitating the structure of steel cables.

The most basic element of a fully stretched steel cable is the steel wire, and the strength of the steel wire itself determines the minimum strength of the steel cable.

Multiple high-strength steel wires are spirally wound together using special tools to form a steel cable.

Then, multiple steel cables of this strength are spirally wound together to form a thicker steel cable.

The combination of two spiral windings greatly enhances the toughness and tensile strength of the steel cable.

If necessary, thicker steel cables can be continuously layered and spirally wound to form an even larger steel cable, thereby increasing the strength of the steel cable.

However, this kind of superposition is not a fundamental improvement, but only an improvement in quantity.

The most crucial element is the steel wire itself.

For Li Yao, the key is not just the chakra threads themselves, but how to increase their strength.

After a long period of calculation and research, Li Yao discovered that he could use acupoint chakra to strongly bind normal chakra, thus binding, compressing and aggregating ten thousand high-speed flowing normal chakra threads together to form a basic chakra thread that resembles a steel cable.

Then, using this chakra thread as the base unit, ten thousand such chakra threads are spirally wound together to form a thicker chakra cable. The cable is then wrapped with a new sealing chakra that combines the high binding properties of acupoint chakra and the high imprisonment properties of Bagua sealing chakra, further enhancing its toughness and strength.

Finally, the new sealing technique's chakra cables were used to connect and form a U-shaped loop of chains.

Then, using this loop, one link after another, they form the final new sealing technique, the Chakra Steel Cable Chain, a new Vajra Lock developed and researched by Li Yao.

The most difficult part is also the very beginning.

The chakra of the acupoints is used to bind ten thousand high-speed flowing lines of normal chakra, compressing them as much as possible into a stable chakra thread.

It's very difficult to take this step.

Li Yao needed to control the flow of 10,000 chakra lines at a speed even faster than the Rasengan, while simultaneously using high-intensity output of acupoint chakra to compress the 10,000 high-speed flowing chakra lines towards the center with high binding power.

Ultimately, the ten thousand high-speed flowing chakra lines are bound, compressed, and aggregated by the chakra in the acupoints to form a stable chakra thread, which is considered a success.

The difficulty lies not in chakra control.

The problem lies in the mental strain; maintaining such precise chakra control is extremely taxing on the mind.

Given Li Yao's current special state of chakra-soul fusion and his control over chakra, he can only achieve a near-stable state. With his current mental state, he cannot break through to the final step in the short term.

However... will Danzo give Li Yao time?
