X-Dragon Era

At this moment, Xin Yun's Four Great Sword Souls had crossed the golden bridge of the Tai Chi Diagram and arrived instantly within Fanghu Immortal Mountain. As it stands, with only one layer of the Tai Chi Diagram unsealed, it's still unable to transport very large objects. Fortunately, the Zhu Xian Four Souls are only the size of soda bottles, so it wasn't a problem.

This Tai Chi Diagram, relying on the principle of Yin-Yang transformation, can open a space channel. Back in the day, the Purple Dawn Palace, before Hong Jun started his lecture, used the Tai Chi Diagram to conjure the golden bridge, allowing listeners to go up and hear it. If it weren't for the protection of the golden bridge, with no saints present at that time, who could have reached the Purple Dawn Palace amidst the chaos?

The principle of this Tai Chi Diagram is essentially spatial folding. If you draw a dot at each end of a sheet of paper, the distance between them is 10 centimeters. To get from one dot to the other, you have to cross ten centimeters. However, if you fold the paper, bringing both dots to the same position, then you simply need to break through the paper, and the two dots become one. This is the principle of spatial folding.

It may sound difficult to understand. How could space fold like paper? However... just because it's difficult to understand doesn't mean it doesn't exist, and being incomprehensible doesn't mean it's impossible. If you were to understand it, then how could the Earth be round? If one's position is at the bottom of the Earth, wouldn't that mean they're head down? How could they not feel uncomfortable!

Furthermore, does the universe have an edge? If it has no edge, how could that be imagined? Even the vast ocean has an edge, so how could the universe be boundless? And if it does have an edge, what is on the edge of the universe? If it's a wall, what lies beyond it?

Many things are like this, impossible to understand just by thinking about them, just like the ancient people who couldn't fathom why the earth was so vast that it had no end, that one could walk a lifetime without reaching its edge.

Inside Fanghu Immortal Mountain, Xin Yun took a deep breath of the rich spiritual energy, to be honest, this place is really perfect for cultivation, with spiritual energy so dense it's reached its limit, any denser and it would form a Spiritual Mist.

The Four Great Sword Souls are existences between avatars and clones, having consciousness and judgment, capable of acting autonomously, possessing spirit and soul, and not much different from living beings, but they exist integrally with Xin Yun.

To put it more clearly, a clone is akin to a smart robot, while an avatar is a separation of one's own consciousness, part of the original being, just temporarily scattered in two places.

If Xin Yun doesn't transfer his consciousness over, these Four Great Sword Souls are like clones, similar to computers—once programmed, they will naturally act according to that program, cultivating and fighting. But once Xin Yun transfers his consciousness over, the Four Great Sword Souls then possess wisdom, able to think and act. In this state, they're akin to avatars.

Nonetheless, an avatar is based on a clone. All thoughts, judgments, and analyses must conform to the clone's protocols. For instance, if Xin Yun's command is to cultivate, then all thinking and analysis must revolve around cultivation and cannot be defied—even the thought of rebellion is impossible.

Now, Xin Yun projected his Divine Sense onto the Four Great Sword Souls. In such times, the Four Great Sword Souls were Xin Yun, and Xin Yun's original body became somewhat akin to an avatar.

With these Four Great Sword Souls, including Xin Yun's original body, as long as one survives, Xin Yun would not perish, and he could swiftly restore any destroyed part.

It's complex when explained, but to put it simply, these Four Great Sword Souls are Xin Yun, and Xin Yun is simultaneously the Four Great Sword Souls. They are one entity, inseparable, sharing both glory and loss. Betrayal is an impossibility—how could one betray oneself?

Having projected his Divine Sense onto the Sword Souls, Xin Yun looked around and then activated the Tai Chi Diagram. The next moment... pieces of jade used for array formation started to fall from the golden bridge one after another.

The Four Great Sword Souls busied themselves together and soon... a medium-sized Eight Directions Energy Gathering Array that covered a range of hundreds of meters was set up. As the array took shape, the spiritual energy within Fanghu Immortal Mountain surged instantly, whistling towards the Eight Directions Energy Gathering Array.

Under Xin Yun's gaze, colorful spiritual energy howled into the array, and in a short while, colorful Spiritual Mist began to condense within. Reaching a hand in, one could distinctly feel the moist spiritual energy, indicating just how dense the spiritual energy in the array was.

With a thought, the Four Great Sword Souls flashed into the Eight Directions Energy Gathering Array, each taking a seat in accordance with the four directions, a Treasure Sword laid horizontally on each of their knees, eyes closed, motionless, entering the state of cultivation.

Although, as of now, the Four Great Sword Souls were only unranked One Star in strength, their advantage lay in the fact that they didn't need to be busy with anything else. Day in and day out, they just practiced Qi and swordplay. Focused and dedicated, their progress was naturally rapid. Furthermore, armed with the knowledge and insights from Xin Yun himself, it was only a matter of time before they would catch up with him.

After arranging the Four Great Sword Souls, Xin Yun withdrew his Divine Sense and returned to his own body with a pleased smile. This unique existence between avatars and clones was truly formidable.

If it were an avatar, one could only have a part of one's own strength, the strength influenced by the original being and never surpassing it. Yet it possessed certain capabilities, with the peak being Laozi's One Qi Transforms into Three Pures, the pinnacle of avatars. However... that avatar is nothing but Primordial Master level strength and could never attain Laozi's level of a saint.
