Those who reincarnate must die.

Diana flipped through the data compiled by the chief engineer, her brain working at lightning speed.

As a reincarnator at the level of a sect leader, Diana's water attribute naturally far surpasses that of ordinary people. She doesn't need a calculator at all; she can summarize and find the hidden patterns in rows of data simply by mental calculation.

As the night deepened, Diana's calculations reached their final stage. She compiled the final data, marked it on the Holy Giant's blueprints, and searched for any errors.

"Um?"

The female dragon knight quickly discovered the problem: while the entire holy giant appeared to be fully illuminated when the energy circulated, data showed that several key nodes were clearly under insufficient pressure, making it difficult to drive the overall operation. Perhaps strengthening these nodes would solve the problem!

This is the only direction we can go!

Diana marked the key locations on the blueprints and wrote down her proposed enhancement plans next to them. She then ordered people to prepare the necessary materials overnight.

Once everything was ready, it was already dawn. Diana stretched, picked up the blueprints, and returned to the underground testing ground.

To her surprise, the chief engineer and workers were already on standby at the test site.

It concerns the life and death of humankind, and no one complains, nor does anyone dare to slack off.

Diana nodded, somewhat touched, and then ordered the prepared breakdown diagrams to be delivered to various posts.

"You've all worked so hard these past years. We've toiled every day in fear and confusion just to survive, all so that one day the Holy Giants can be resurrected, those otherworldly monsters can be driven back to their lair, and the gates to the other world can be sealed forever!"

"Once, this was an unattainable goal, and even I wavered more than once. But now, the greatest difficulty has been overcome. What we need to do is keep experimenting until we awaken this ancient weapon of war!"

"Believe me, we can save this world! Let our names be sung by future generations!"

"Save the world! Save the world!"

Although yesterday's test failed, the workers remained enthusiastic. After receiving the blueprints and materials, they immediately got to work and, after a morning of debugging, were finally ready!

"Alright, still using Plan 4C. All departments, to your positions. Ready, go!"

With the chief engineer's order, the equipment in the entire test site started operating organically. Accompanied by the turning of gears and the roar of steam, mechanical arms worked in an orderly manner on the remains of the Holy Giant, and powerful energy was injected into various key nodes on the Holy Giant's body!

"The entire left arm is lit up!"

"Right leg is fully lit up!"

"Left leg lit up 85%!"

"Right arm lit up 77%, 78%, 79%..."

"Both legs are fully activated! The magic is beginning to extend towards the hips!"

"The torso is starting to light up! Current progress: 23%!"

…………

As reports came from various posts, the magical runes all over the huge holy giant's body began to shine, and they looked noticeably brighter than before!

Diana gripped the railing, looking down excitedly, her hands involuntarily squeezing the thick iron pipe until it deformed.

"We must succeed!"

The magical runes carried the electricity all the way to the holy giant's forehead, until even his massive horns shone brightly!

Everyone held their breath, watching expectantly as the enormous skeleton appeared!

After a silence of more than ten seconds, just as Diana was beginning to lose hope and preparing to face the giant's renewed gloom, suddenly!

A dazzling light shone from the blood pool, and the resulting high temperature evaporated the red liquid. The entire blood pool began to bubble and fizz, and the entire test site became like a sauna doused with water in a charcoal oven, with the temperature rising significantly!

The direction of that light... was towards the chest of the Holy Giant!

It is the core of the mountain range!

The core of the mountain range has been activated!

Once the energy problem is solved, the rest will fall into place!

As energy was poured in, the organic core installed in the abdomen of the Holy Giant immediately began to operate wildly. The boiling blood around it began to churn abnormally, all rushing towards the giant's body. Under the action of the organic core, it condensed into thick flesh and blood, which clung to the skeleton.

As the giant's body rapidly remodeled, the liquid level dropped at a visible rate. Simultaneously, wisps of black liquid began to swirl around the mountain's core and organic core, accelerating their circulation!

It's the black waters of the Styx!

This extremely cold liquid, retrieved from the underworld, primarily serves to cool and dissipate heat from the giant's body. With the protection of the black water, the rapidly rising temperature will begin to decrease!

As the body continued to recover, the orange gem on the holy giant's forehead began to emit a soft light.

It is the eye of the soul!

Diana leaned forward excitedly. The activation of the Mind's Eye meant the giant's soul was beginning to awaken!

Under Diana's gaze, the newly formed muscles on the Holy Giant's cervical spine began to contract, slowly pulling and straightening the enormous head.

Then, the head slightly lifted, the thick and huge eyelids opened, and four golden eyeballs slowly formed in the originally empty four eye sockets.

The moment Diana was looked at by those four enormous eyes, she felt as if she had been electrocuted. She staggered back two steps, nearly collapsing on the platform.

"This is terrifying! Just a glance from someone half-asleep has such power, enough to make even a hero like me lose my composure. If it were to fully recover, what an incredibly powerful being it would be!"

Diana, stunned, broke into a look of ecstatic joy: "With such a powerful weapon, we can definitely save our world!"

However, Diana's joy did not last long. The resurrected holy giant suddenly began to writhe restlessly, seemingly dissatisfied with his current situation. He raised his massive arm and swung it, smashing a platform on his right into a bloody pulp, killing the workers on it instantly!

"The Holy Giant is out of control!" the chief engineer shouted. "Don't panic, quickly control it, inject sedatives!"

With the sounds of gears and steam, workers manipulated mechanical arms to grab at the giant, attempting to control its movements. However, even without full recovery, the Holy Giant's strength far surpassed that of mere machinery. With a shudder, it shattered all seven or eight mechanical arms that were pressing against it. Turning back, it saw the giant needle that had just been prepared, grabbed it, and hurled it towards the chief engineer!

The chief engineer was so frightened that he collapsed to the ground. As the enormous needle came crashing down, he could only close his eyes and wait to die.

At the critical moment, Diana rushed forward, caught the syringe, turned around, leaped, and plunged the needle into the giant's body, then injected the sedative...
