My System Is Three Thousand Years Early

Thanks to Cheng Guang's advance warning, Duke Zhen Guo, Cheng Shiyuan, had long since made preparations. The vast majority of the soldiers in the Northern Expedition Army were arranged to patrol and guard near North City, without being dispatched deep into the Border Area battlefield.

Therefore, it was possible to call back all the soldiers of the Northern Expedition Army to the city at the first sign of trouble, preserving all of their combat strength.

The million-strong Northern Expedition Army was gathered within North City, a sight that was bustling, majestic, and awe-inspiring.

There was not a single person in North City who could not or would not fight.

Should hostilities break out, even an ordinary cook, responsible for making meals, would cast aside their apron, hang up their chef's hat, don armor, take up arms, and ascend the city walls to fight side by side with the Demon Beasts that might attack at any moment.

Cheng Guang took steps one by one within Duke Zhen's Mansion, heading towards the direction of the storeroom.

With the Devil Transformation Armor, a Different Treasure he now possessed, as long as the armor absorbed and recorded a Ninth Grade demon core, he would be able to exhibit strength not inferior to the Eighth Rank.

Ordinary warriors of the Eighth-Rank King Realm were no match for him, only those strong individuals in the Ninth-order Martial Emperor Realm could possibly defeat him.

The location of the storeroom was in the inner courtyard of Duke Zhen's Mansion.

Upon reaching the inner courtyard and arriving at the storeroom, he found it unguarded due to the imminent outbreak of war.

Cheng Guang walked up to the storeroom door and pushed it open to enter.

The sight within the storeroom came into view.

Square wooden racks filled the entire storeroom, and on these shelves, a chaotic and disordered array of resources, which were incredibly precious in the eyes of ordinary people—Spiritual Medicines—were laid out.

An ordinary person entering this storeroom might instantly become lost, overwhelmed by the bounty before them.

Faced with these Spiritual Medicines, which would be extremely valuable in the outside world, Cheng Guang felt little impact.

Perhaps it was because he had grown accustomed to seeing such sights.

Cheng Guang walked among the wooden racks, searching each level in an attempt to find the demon cores.

Demon cores were relatively easy to find; by following the presence of Devil Qi, one could locate them in a short while.

Cheng Guang quickly found a wooden box of demon cores on the lower section of a tall rack.

Various colored demon cores were piled casually inside the wooden box.

The multicolored demon cores, still emitting different colored glows due to the Devil Qi, caught the eye.

Cheng Guang scanned them briefly and realized their auras were not very strong—most of them were Fifth or Sixth Grade.

Even if the Devil Transformation Armor were to record these demon cores, the enhancement in Cheng Guang's martial strength would be minimal, at best described as better than nothing.

After searching the storeroom a while longer, Cheng Guang swiftly found a Ninth Grade demon core on the top level of a rack.

This Ninth Grade demon core seemed to have been acquired some time ago and hadn't been used in a long time, resulting in the demonic power on its surface becoming exceptionally weak.

It still took Cheng Guang quite an effort to find this Ninth Grade demon core.

Afterward, he continued his search but to no avail.

Duke Zhen Guo, Cheng Shiyuan's claim that there were many Ninth Grade demon cores seemed not to be entirely true.

Members of the Devil Clan with the strength of the Ninth Grade were only slightly less formidable than the Devil Emperor. In North City, they'd be on the same level as an existence like Qin Beifeng. Although obtaining their demon cores was easier than acquiring a Devil Emperor's core, it was still not an easy task.

Having even one Ninth Grade demon core was not bad at all.

Cheng Guang wasn't choosy. After all, the Devil Transformation Armor could only record one demon core. If he later obtained a more powerful demon core, it wouldn't be too late to replace it then.

For now, he could make do with this Ninth Grade demon core.

Cheng Guang held the Ninth Grade demon core in his hand and examined it closely for a moment.

The demon core was white and red, with a ring of flame-like patterns around it, giving off a quite devilish appearance.

It was unclear which breed of Devil Clan power this had come from.

Cheng Guang pondered in his heart, and with a slight thought, he summoned the Devil Transformation Armor and pressed the Ninth Grade demon core into the groove in the palm of the armor.

When the Ninth Grade demon core was pressed into the groove in the palm of the Devil Transformation Armor, strands of light in the same color as the demon core streamed out from it.

It was like a pebble being thrown into a calm lake, creating ripples that spread out in concentric circles.

The Devil Transformation Armor on Cheng Guang's body was quickly dyed the color of the Ninth Grade demon core.

The whole armor took on an interspersed white and red coloration.

At the same time, Cheng Guang noticed his body gradually growing larger, akin to a mountain in motion, conveying an overwhelming sense of oppression.

His muscles writhed under the Devil Transformation Armor, which, under the influence of the demon core, was transforming into skin as hard as armor.

His limbs became thicker, and his fingers resembled beast claws, sharp and formidable.

Above all, the most astonishing change was on Cheng Guang's head.

The helmet, under the effect of the demon core, took on the lifelike shape of a beast's head, resembling an aged land turtle, with eyes gleaming fiercely and a mouth full of sharp fangs.

When Cheng Guang had completely transformed, he resembled a Desolate Armored Devil Beast that had stepped out of ancient times, surveying the surrounding world with a chilling gaze.

This was the Devil Transformation Armor after merging with a demon core—it was no longer just a simple piece of armor, but rather it made Cheng Guang a true Devil Beast, becoming part of his body.

Cheng Guang lifted his hand slightly, marveling at the changes in his own body, astonished by the magic of the Devil Transformation Armor.

At the same time.

Cheng Guang also discovered that as he took on the full appearance of a Devil Beast, fragments of memories from the life of this beast unbiddenly surfaced in his mind, and the techniques once used by this beast were now approximately within his grasp.
