Those who reincarnate must die.

"What else do we need?"

The reincarnators are very concerned about the side quests.

"These two things are even harder to obtain than the Eye of the Mind..." Diana sighed and said, "They are the Styx Blackwater and the Organic Core."

"What is that?" Ye Peng asked, completely bewildered. "It sounds really powerful!"

"The organic core can be found in the alien mother nest in the abyss, while the Styx Black Water, as the name suggests, needs to be retrieved from the Styx River in the underworld."

"To other worlds?" Yue Xinyi asked in surprise. "Isn't that a bit too much to ask?"

"Rather than difficulties, it was the appearance of the otherworld that provided a turning point for the resurgence of the Holy Giants," Diana explained. "In fact, the Holy Giants are heroes from ancient legends. According to mythology, the ancient world was invaded by monsters from another world. At the critical moment, an enormous giant descended from the sky, helping humanity repel the monsters and finally sealing the gate to the other world with his own life, thus saving the world from disaster forever."

"For many years, we believed that the Holy Giant and otherworldly monsters were just legends, until more than a hundred years ago, when the Sanctuary discovered a huge humanoid skeleton. After research, the skeleton was found to belong to a powerful creature unknown to humankind, which closely matched the legendary Holy Giant. The Sanctuary regarded this skeleton as a sacred object, carefully preserving it, and even attempted to use life magic to bring it back to life. However, the Holy Giant was too powerful and had been dead for too long, and the research on resurrection made no progress."

"Later, I entered the altar, and my magical skills improved by leaps and bounds. With this, I entered the Holy Temple's research institute and came into contact with the project of regenerating the Holy Giant. Using the knowledge from the altar, I proposed a completely new idea: to use mechanical assistance to reshape the giant's body."

"After several discussions at the research institute, everyone agreed that my plan has the highest theoretical feasibility at present, but there are still a few difficulties."

"First, the Titan's body cannot be entirely driven by machinery; it still requires at least 20% organic flesh. Second, the Titan's soul cannot be reborn and needs to be controlled, but ordinary people's mental strength cannot support the Titan's powerful body; a powerful mental strength amplification device is necessary. Third, driving the Holy Titan's enormous body requires a massive amount of energy. Fourth, such a massive energy output generates enormous heat, requiring a powerful cooling system."

"To solve these problems, we searched the world and tried every possible method, but to no avail. The Holy Church even abandoned the revival plan at one point. Until then, the gate to another world opened..."

At this point, Diana sighed, seemingly unable to bear recalling that painful experience.

"Initially, while suffering invasion, humanity fiercely resisted with its massive military force, even launching a counterattack into another world. There, we witnessed a world completely different from our own and encountered unprecedented power. It was there that we found hope for the revival of the Holy Giants!"

"Legend has it that the Holy Giants defeated the monsters from another world and saved the world. For the sake of humanity's survival, we must also resurrect the Holy Giants! To this end, humanity launched a desperate counterattack, and at the cost of blood and fire, successfully brought back two treasures from the other world!"

"Is that Eye of the Mind one of them?" Yue Xinyi asked. "Is that the mental amplifier used to control the giants?"

Diana nodded: "That's a treasure from the Savage World. Compared to other worlds, the Savage World doesn't have many mainstream intelligent races. Although the monsters there are very powerful, most of them act on instinct and are not organized. Their invasions of humans are the gentlest. Our Griffin family sent an expedition there many years ago and found the Eye of the Mind, which we have kept until now."

"And what about the other one?" Lu Ren asked hastily, engrossed in the story.

"Another treasure comes from Hell," Diana said. "In contrast to the wilderness, Hell, although it has all kinds of demons, most of them are intelligent and ruled by a demon king. The entire Hell can be seen as a huge army, and its attacks on the human world are the most ferocious. However, the vast majority of this army consists of lower-middle-level demons below level three, and their strength is not great. Therefore, in the early stages of the interdimensional invasion, it was basically a war between humans and demons, with both sides fighting back and forth. We even launched a counterattack into Hell at one point."

"It was around that time that we obtained something from Hell that constantly emitted heat, which the demons called the Core of the Mountain. This thing was just the right energy source to power the Holy Giants."

"The core of the mountain?" Mentioning this, Zhang Lang, who had slaughtered his way through hell, raised an eyebrow: "Is it a huge, semi-molten rock?"

"You've seen it too?" Diana sighed. "It was because we stole this thing that we angered the Demon King, and all sorts of high-ranking demons joined the battle, causing us to begin our retreat. In addition, more and more monsters from other worlds appeared, ultimately leading to the complete fall of the human world..."

Zhang Lang nodded: "I've seen more than one. They exist in every level of hell, usually under the largest volcano... Only the top level doesn't have one. So you guys stole it."

"What? You've seen every single one of them?"

Diana's eyes widened. As a reincarnator, she understood the mission of the Twelve Altars and knew they had escaped from Hell... However, judging from Zhang Lang's tone, the word "escaped" seemed somewhat inaccurate...

"That's not important." Zhang Lang waved his hand. "The remaining two are the Styx Blackwater and the Organic Core?"

"Yes," Diana nodded. "The Styx River's black water is the coldest thing in the world, capable of freezing even the soul, making it the perfect coolant. And the organic core, when activated by magic, can to some extent reshape the body of a holy giant. However, both of these are in another world, and we haven't had a chance to get our hands on them yet."

"To find it, you have to go to another world..." Zhang Lang stroked his chin and asked rhetorically, "What use is a resurrected Holy Giant, besides being used as a weapon?"

"Um..." Diana thought that being able to use it as a weapon was already its greatest function... However, intimidated by Zhang Lang's strength, she honestly answered, "The Holy Giants are still the only known method to completely seal the other world!"

"Since the invasion of the otherworldly monsters, the interdimensional gate has been in an unstable state, opening and closing intermittently. It is precisely because of this that humanity has had a respite, allowing us to hold on until now. We have searched everywhere for methods, and the only recorded way to permanently close the interdimensional gate is through the Holy Giant!"

"I see..." Zhang Lang nodded. "Okay, I'll go get those two things for you!"
