This weapon, named Shenying Essence Cannon, as the name suggests, can gather the essence of heaven and earth, then condense it into an essence cannonball and fire it out.

According to the description on the incomplete jade tablet, if this cannon is fired with full power, it can blast a thousand-zhang land into ruins, and evaporating a small mountain or lake is entirely within its capabilities.

However, once this shot is fired, the Shenying Essence Cannon will quickly weaken.

It needs a full quarter of an hour to rest and recharge before it can fully recover its combat strength.

But even with such a long recovery time, to be honest, it is much stronger than many people.

At the same time, perhaps considering that if the battle situation was too intense, a single shot every quarter of an hour would indeed be insufficient.

Therefore, the person who designed the Shenying Essence Cannon also thoughtfully installed an energy absorption device inside the Sky Steel Kirin.

This allows the person sitting inside the giant machine to recharge the essence cannon above their head by consuming their own magical power.

This way, there are no restrictions; as long as there is enough magical power, one can fire as many shots as desired, making the opponent scream.

Besides this eagle-head essence cannon, the twenty-four Qilin-head blades embedded around its body are also a type of weapon.

Furthermore, they are so hard and sharp that they can easily cleave open the body of an initial-stage Grandmaster.

According to the records on the jade tablet, these small blades can be remotely controlled by the person sitting inside the machine through the internal mechanisms, much like controlling a drone, and the control range completely overlaps with the person's mental perception range.

In summary, this Sky Steel Kirin can also be considered a rare Grandmaster-grade secret treasure.

However, what Li Hai truly cared about was the domineering and handsome appearance and aura of this giant machine at first glance.

It felt quite showy.

So he decided that this Qilin machine would be his future mode of transportation.

As for the people to carry the machine, he would use Dao Ge Four, his four demon-subduing powerhouses.

It's just that the current strength level of Dao Ge Four is too far from Li Hai's, so it felt a bit low-class.

If the people carrying the machine were replaced with four Grandmasters, it would be more befitting of Li Hai's status.

Perhaps Li Hai's regretful thought somehow worked, because he subsequently discovered a large group of higher-Rank demon-subduing powerhouses in a new building he unlocked, the North Forest Garden.

This North Forest Garden, like the Eastern Forest Garden that Li Hai had previously unlocked, was a vast wasteland, uninhabited and treeless.

Similarly, in the depths of this wasteland, there were over a hundred remains of demon-subduing powerhouses.

And the aura emanating from these powerhouse remains was significantly stronger than those in the Eastern Forest Garden,

almost at the Grandmaster-Rank.

But regrettably, Li Hai walked around and around in these piles of remains several times, but failed to successfully activate any of the high-Rank demon-subduing powerhouses.

Clearly, these ancient powerhouses were too thoroughly damaged and were now completely “dead”.

However, just as Li Hai felt regret about this, Dao Ge Four, who had arrived at this place at his thought, brought him good news.

The news was that although these high-Rank demon-subduing powerhouses were all “dead” and inactive, the many high-Rank components within their remains still possessed extremely high value.

They could be used to replace many of the low-Rank components on Dao Ge Four, thereby allowing them to complete a version upgrade and significantly improve their strength.

However, this kind of component replacement and upgrade, which involved the entire internal and external structure of the body, simply could not be completed by Dao Ge and his few low-Rank powerhouses.

A complete Powerhouse Workshop would be required to complete such a “major surgery” for version upgrade.

But where could Li Hai find such a workshop for them? So, the matter of Dao Ge Four's version upgrade could only be temporarily put aside.

After this matter concluded, Li Hai unlocked another new building in Guiyou Cave Heaven, and this building was none other than — the Cultivation Technique Library.

For the Cultivation Technique Library he had longed for, he conducted a thorough search, as if scraping the earth three feet deep.

After a thorough search, Li Hai found two Perfect Grandmaster-Rank Cultivation Techniques, ten lower-level Grandmaster-Rank Cultivation Techniques, twenty-six Thousand Army Grade Cultivation Techniques, and fifty-five Steel Grade Cultivation Techniques.

Li Hai was extremely satisfied with this harvest, and then he stayed in this Cultivation Technique Library, learning all ninety-three martial Dao Cultivation Techniques, each with its unique characteristics and Rank, and pushing them all to the Peak level, making his skill bar and attribute bar grow longer, and also deepening his martial Dao foundation by three points.

Perhaps his luck had truly arrived.

In the time that followed, the new building Li Hai unlocked after exhausting all his remaining soul remains was surprisingly a Powerhouse Workshop.

And after bringing Dao Ge Four into this workshop, Li Hai discovered that although it had been ravaged by the long years and was now dilapidated,

its various machinery and tools had miraculously been preserved and were very complete.

So, in his surprise and joy, Li Hai immediately ordered Dao Ge Four to quickly return to the North Forest Garden, dismantle all the high-Rank components from the powerhouse remains, and transport them to this workshop.

Then, after several more hours, a large pile of high-Rank components dismantled from the powerhouse remains in the North Forest Garden were all transported to the workshop by Dao Ge Four.

Thus, the version upgrade for Dao Ge Four officially began.

First to be dismantled and replaced was the essence energy furnace that supported all their energy consumption.

Next, it was the spirit source concentrator that ensured the short-term burst power of the demon-subduing powerhouses.

Then, it was the replacement and upgrade of the energy conduction network, the Spirit Silk Silver Veins, which permeated and covered all parts of Dao Ge Four's bodies, both inside and out.

After that, it was the version upgrade of the two major components that supported the demon-subduing powerhouses' basic intelligence and reaction capabilities: the Spiritual Insight Intelligence Core and the Spiritual Insight Sensor Array.

Then, it was the major upgrade of the demon-subduing powerhouses' internal skeleton, the Golden Adamantite Bones, the Spiritual Pivot Joints connecting each bone, and the complete set of Crystal Cluster Armor covering the powerhouse's body surface.

Finally, after upgrading these basic components, it was the assembly and installation of Dao Ge Four's other high-Rank external components.

These so-called external components were: the Sky-Riding Feather, which could provide high-speed aerial flight; the Spirit Guard Talisman, which could form an energy shield outside the body to enhance defensive capabilities; the Evil-Slaying Fierce Blade, which could be augmented with exorcism spells for hyper-oscillation, capable of cutting both physical entities and ghosts; and the pure black face-covering cloak-like Anti-Law Spirit Engine, which could be worn to absorb and immunize against spell attacks below the Fourth Rank, while also partially exempting from the effects of some Fourth Rank spells.

And after completing all these modifications, Li Hai conducted a few tests and discovered that Dao Ge Four's defense, reaction, attack, strength, agility—everything—had all risen to the pseudo-Grandmaster level.
