Around him, those collecting spiritual sources kept making moves, storing away the flying spiritual sources.

Even though the siege outside was deafening, Su Yang and the other guards still firmly held the mountain.

Previously, Su Yang was puzzled as to why they did not go out to help those guarding the city.

But soon, Su Yang learned the reason.

As more and more spiritual sources appeared, the city finally erupted into a great battle.

Groups of people began to attack those defending the city within the walls.

However, Bright City had been prepared in advance, so they had defenders inside, combining forces to resist the attackers.

Seeing this situation, Su Yang couldn't help but recall what Lin Ye mentioned earlier.

Each main city would plant its own people in other main cities. The purpose was that on the Spiritual Birth Day, if their own main city lacked spiritual sources, they could cooperate to steal from other cities' spiritual sources.

Those attacking within the city were undoubtedly people planted by those main cities in Bright City.

Two city lords made their move, restraining the Bright City Lord. Their subordinates were besieging outside, while internally, were those they had planted long ago to attack within.

Watching the chaos outside, Su Yang was also shocked.

These were mighty Saint Emperors, fighting to this extent for some spiritual sources. In this short period, Su Yang saw several Saint Emperors fall. These Saint Emperors were like beasts fighting desperately for food; they had no choice but to risk everything for spiritual sources!

As the battle grew more intense, it gradually spread to the Spirit Birthplace. Some people planted in the city started to attack the Spirit Birthplace.

At this moment, the guards of the Spirit Birthplace finally became useful. Their task was to guard the Spirit Birthplace and not let any outsiders approach.

Su Yang and his team were stationed further inside, still relatively unscathed, as the battle hadn't yet reached them. But outside, the battle had reached a fever pitch, with both sides fighting desperately just to seize these spiritual sources.

The battle lasted for three days and three nights, and it's unknown how many casualties there were. The scope of the fight was almost reaching Su Yang's area.

At this point, the number of spiritual sources appearing also began to decrease, and their quality started to deteriorate.

Undoubtedly, this was nearing the end.

The guards of Bright City were indeed strong, somehow preventing people from the two cities from approaching the Spirit Birthplace, which was truly not easy.

At this moment, Su Yang noticed movement from the group of the Nine Palace Chief God.

They had been standing at the canyon's edge, waiting all along. With the spiritual sources appearing less and less, they actually moved further toward the canyon, as if observing something.

Su Yang couldn't help but wonder, since they didn't want the spiritual sources, what were they waiting for?

Su Yang kept a close watch on these people. After about half a day, the leading Nine Palace Chief God had a sharp glint in his eyes. He waved to the people beside him and suddenly jumped straight into the canyon.

Su Yang almost cried out, wasn't it said that there's no return from below the canyon? What exactly were these Guardian Gods up to? What did they mean by jumping down?

Some guards nearby were also full of surprise, unable to understand the intentions of these Guardian Gods. However, remembering the Bright City Lord's previous instructions, no one said anything. If these Guardian Gods wanted to die, so be it!

After pondering for a moment, Su Yang suddenly gritted his teeth and sent a message to the three Crystal Skulls: "You three wait here, I'll go down and take a look!"

He finished speaking and, without waiting for their reply, followed by jumping down as well!

Immediately, the surrounding guards were stunned.

It's one thing for the Guardian Gods to jump down, as their life or death didn't concern them. But now a guard from their side also jumped, what was going on? Didn't this guard know that jumping from this place meant no return?

The three Crystal Skulls were also bewildered. When coming here, Su Yang repeatedly reminded them not to fall into this canyon. Now things had reversed; they hadn't gone down, but Su Yang did. What did this mean?

Of course, with the ongoing chaos, there were few who actually noticed this situation. Moreover, as the battle outside gradually approached, everyone's attention shifted to the external battlefield, ignoring this side's situation.

Su Yang jumped into this canyon mainly because of the Nine Palace Chief God's group. Even though Feiyu had previously mentioned the situation inside the canyon, warning him of no return, with the Nine Palace Chief God's group jumping, Su Yang had no reason not to jump in too.

These Guardian Gods surely valued their lives. If they dared to jump in, it meant they were aware of the situation inside and knew it wasn't dangerous. Why would Su Yang hesitate?

Furthermore, this matter involved Su Yang's mother, and he wouldn't give up any possibility. The Nine Palace Chief God's group acted mysteriously, and Su Yang was determined to follow them in to see clearly what they intended.

This canyon, viewed from the outside, seemed endless. Moreover, the deeper it went, the darker it became, making it impossible to discern the situation inside.

At the Saint Emperor's level, even the darkest place would seem as bright as day. Yet, the darkness within this canyon was so profound that even a Saint Emperor couldn't see through it, which was truly strange.

Falling all the way down, Su Yang estimated his current position.

The area of the trunk was once the location of the World Tree's main trunk. The World Tree was gone, leaving this hollowed space. Hence, inside the trunk, it was essentially an empty space without terrain, with few hills present.

Of course, there were exceptions, with a few small hills here and there. Su Yang gradually understood that these small hills were actually part of the little branches off the main trunk, merely slight protrusions within the main trunk.

In other words, the bottom of this canyon was actually the trunk's edge. And crossing the trunk's edge meant entering the realm of chaos?

Chaos was extremely dangerous; contact would lead to assimilation into a chaotic state. So, Su Yang had to calculate his altitude and position carefully to avoid contact with chaos, which would spell disaster.

After descending for a few minutes, Su Yang calculated that he was not far from the trunk's edge. At this moment, he couldn't see the outside situation at all, indicating it was the right time for action.
