And now, the Mystic Mechanism World is no longer a game, but some of the players' restrictions still exist, like the initial underpants that players can never shed.

However, Liang Yi found out through the information he obtained that this restriction has been lifted in the Abyss!

That is to say, the players who are currently in the Abyss are truly one hundred percent free!

So, right now, Bai Xiaomo, Ju Xiaobei, and the others are really touring the Abyss during their spare time from missions.

Even though the atmosphere in the Abyss is completely different and horrendously vile compared to the Mystic Mechanism World, the adaptability of players is among the world's best, allowing them to find their own fun without revealing their identities.

"But what is this Heavenly Vein Spirit Core? Why have I never heard of it before..."

Zhou Wudao and Zhou Zuixi pondered for a long time but still couldn't find any information about the Heavenly Vein Spirit Core in their minds.

"Spirit Vein" is indeed mentioned in the scriptures of Xuanzhou's Immortal Dynasty, referring to an area where Spiritual Power is extremely condensed to the utmost degree, merging with some rare ores to form a solid spiritual entity.

The spiritual coins used in the Cultivation World are produced by extracting from the Spirit Veins, which is why they contain extremely pure Spiritual Power and have a wide range of uses.

"Heavenly Vein Spirit Core... does it have something to do with the Heavenly Dao?"

Ke Mengzhan had not heard of this either, but his intuition told him that it must be related to the Heavenly Dao.

"Not exactly. It's not just about the Heavenly Dao, it's about an entire world."

The one who spoke up was Zhou Yuzhi; he was not only explaining to Ke Mengzhan but also to everyone else.

"You know about energy nodes, right?"

Zhou Yuzhi casually drew several lines with Sword Qi in the void, and these lines intersected at one point.

"I know, many times region divisions are based on the flow of Spiritual Power, and many major cities are mostly built on energy nodes."

Zhou Wudao spoke in time.

These things were not unfamiliar to him – after all, he was the crown prince of Xuanzhou's Immortal Dynasty and was quite knowledgeable about such matters.

On the Mystical Mechanism Continent, Spiritual Power exists everywhere, but it is not evenly distributed. Some places are extremely abundant in Spiritual Power and are known as Cave Heaven Blessed Lands, while others are Spiritually barren, disfavored by Cultivators.

The most abundant and richest place in an area of Spiritual Power is called an energy node.

Xuanzhou's Immortal Dynasty and most Super Forces divide their territories based on the flow of Spiritual Power, and key cities are also established on energy nodes, which are beneficial to both commoners and Cultivators.

"Yes, that's right! And by comparison, the Heavenly Vein Spirit Core is the energy node of the Abyss's massive world."

Zhou Yuzhi nodded approvingly, glanced at Zhou Wudao with respect, and then pointed his finger at the intersecting point of the lines in the void.

"And as long as it is destroyed, the Spiritual Power of the Abyss will instantly become chaotic. The whole world will gradually move towards the depletion of Spiritual Power! Geniuses and treasures will no longer be born, Cave Heaven Blessed Lands will become mediocre, possessing supreme Cultivation Techniques but unable to cultivate, and Cultivators will gradually come to an end!"

Zhou Yuzhi's words were as cold and hard as his sword. As he spoke, everyone envisioned apocalyptic scenes, shivering involuntarily, and felt a bone-deep chill.

Everyone was shocked by the thought, but it was undeniable that if they indeed could do it, the tide of battle would reverse once more! The scales of victory would turn to their side!

"So our mission is... to destroy the Heavenly Vein Spirit Core of the Abyss?"

Ke Mengzhan asked hesitantly.

He was not a man of indecision, and although he seemed a bit frivolous usually, he had always been resolute when dealing with the Abyss – it's either kill or be killed!

Yet at this moment, Ke Mengzhan's heart faltered for the first time. Differing from the past when eliminating thousands with a single strike, if they really succeeded this time, they would be destroying a world!

How many lives are in a world? Ke Mengzhan dared not think and could not comprehend...

"This is war!"

Zhou Yuzhi looked deeply at Ke Mengzhan.

This disciple of his not only had superior strength and character but also the resolve to face the Abyss.

Had the war proceeded normally, Ke Mengzhan might never have encountered this choice, with the older generation shouldering the consequences and sins.

But now it was different; this special choice could only be left to them to make – it was a transformation!

Liang Yi and Su Youyi also came to this realization, their expressions filled with hesitation and indecision.
