Monk Wu Nian's strength is about the same as Su Yang's now.

And nowadays, in the Human World, compared to Su Yang, the strength of Beigong War God Qi Zhishan and the others is considerably weaker.

So, if Yang Wudi really comes to the Human World, perhaps even if Su Yang and the others join forces, they can barely contend with Yang Wudi!

Of course, this is based on the assumption that the combat power of the three Crystal Skulls is somewhat stronger than that of Beigong War God and the others.

To be honest, Su Yang really isn't sure how strong the combat power of these three Crystal Skulls actually is.

The aura of these three entities suggests that their strength is not weak. In fact, in that city filled with Yin energy, their aura is even stronger than Su Yang's.

However, after coming out, the aura of these three entities began to weaken, probably because they left the Yin energy. After all, these three were born from the Yin energy, and their strength can only reach its peak in that city full of Yin energy.

So now, Su Yang isn't sure what level the combat power of these three entities is at. He can only assume they are slightly stronger than Beigong War God and the others but still far from the realm of Gui Xin.

Now that the situation is clear, Su Yang instructs everyone to tidy up and begins heading toward the Feather Spirit Palace Main Hall.

Judging by the time, the big battle should be wrapping up, and it's time for Su Yang to step in.

As for the people from the Buddha Domain, the Demon Realm, and the Ghost Realm, Su Yang temporarily ignores them. Without Su Yang leading the way, it's not easy for these people to reach the main hall after entering the Feather Spirit Palace.

Before long, they reached the rear.

Walking through the area separating the front and back courtyards, the three Crystal Skulls following Su Yang shivered involuntarily.

Su Yang looked at the three entities in astonishment. Can a skeleton frame shiver?

Seeing Su Yang's astonishment, the Second City Lord transmitted a message: "I… I feel like someone is watching us..."

"What on earth?" Su Yang replied in surprise, also transmitting his message back. He had previously instructed the three entities not to speak carelessly outside to avoid exposing their identities. So, even though they were surrounded by members of the Human Clan, they still communicated through telepathy.

Although Su Yang completely trusted Beigong War God Qi Zhishan and others, there was still Second Young Master Zhang accompanying them.

Su Yang admired the Martial Champion, but that admiration was limited to his command at Jieyue Tower. It didn't mean Su Yang admired everything about the Martial Champion.

For instance, the Martial Champion was extremely protective, and many members of the Zhang Family were arrogant and domineering. Moreover, the Martial Champion had invested considerable effort into ensuring that his descendants could continue the Zhang Family's glory after his departure.

Furthermore, the Dean had previously mentioned that the Martial Champion's concerns were focused on the Nine Realms. The survival of the Human World, to him, was not particularly significant.

Considering these aspects, Su Yang remained cautious of the Martial Champion. Who knows if the Martial Champion might sacrifice the Human World to protect the Nine Realms?

For those who guard the Nine Realms, if they had to choose between the Nine Realms and the Human World, they would undoubtedly choose the Nine Realms, not the Human World!

"I don't know either." the Second City Lord replied. "It just feels like someone is watching us."

Su Yang looked around blankly, but he didn't feel anything.

"From which direction?" Su Yang asked, wondering if they were nearing the main hall and if something from inside was watching them.

"I can't tell, it seems like it's coming from all directions," the Second City Lord responded.

"All directions?" Su Yang was stunned. Was the Second City Lord mistaken, or had the situation changed? Wasn't it said to be coming from the main hall?

Su Yang looked toward the Great City Lord, whose eyes were serious and whose expression was much more grave than the Second City Lord's.

"Many directions, seems like more than one person is watching us," the Great City Lord paused, then looked in a particular direction: "There's one over this way, feels like it's the closest to us."

Looking up toward the direction the Great City Lord indicated, Su Yang was puzzled because he had passed through here earlier, and there was no one. Who could the Great City Lord say was watching from there?

Judging by where Su Yang had passed earlier, only those from the Four Realms could be nearby at this time.

However, even if they were as strong as Wei Qing or Ye Xingjun, they were only about as strong as Su Yang.

If they were the ones watching the Great City Lord and others, Su Yang should be able to feel it. Besides, if they were indeed watching, their focus would be on Su Yang, who had tricked them earlier, not the three Crystal Skulls.

So, Su Yang could confidently conclude that the ones watching the three Crystal Skulls were definitely not from the Four Realms but were actually people originally from the Feather Spirit Palace.

Why would people from the Feather Spirit Palace watch the three Crystal Skulls? Could it be that these three Crystal Skulls have some relationship with the Feather Spirit Palace?

Or perhaps there's indeed some connection between the World Melting Furnace and the Feather Spirit Palace?

Moreover, the Great City Lord mentioned that there's more than one person watching them, suggesting there are several watchers.

This revelation further astonished Su Yang. Could there really still be so many people inside the Feather Spirit Palace?

The Feather Spirit Palace has been in the Human World for thousands of years. Discovering a living person inside would be enough to shock the Nine Realms.

Yet, given the current situation, there isn't just one person, but potentially many alive inside, which is even more astonishing.

Of course, the masked person from earlier doesn't count. Since that masked person couldn't enter the Feather Spirit Palace, they obviously couldn't be from inside it.

Suppressing the shock in his heart, Su Yang led everyone in the direction the Great City Lord indicated.

Having come this far, Su Yang certainly wanted to explore the situation inside the Feather Spirit Palace. After all, this was their objective in coming here in the first place.

Not long after, a small palace appeared ahead, and above it was a damaged Tai Chi Diagram.

This small palace was the place Su Yang had been to before. At that time, Wei Qing had sent three people into this small palace to take the Tai Chi Diagram. And Ye Xingjun had also sent three people, presumably to seize the Tai Chi Diagram.

When Su Yang slipped away earlier, he specifically avoided this place to prevent running into Wei Qing's subordinates and causing trouble. So he didn't know whether Wei Qing's subordinates had taken the Tai Chi Diagram or not.

Looking now, the Tai Chi Diagram was still there, and Su Yang breathed a sigh of relief. This Magic Artifact mustn't be taken by Wei Qing's people at all costs.
