We arrived at the center of the Azure Sky Galaxy.

"This city of Tianfang is something else!"

Seeing the magnificent city standing tall in the void in the distance, Mo Tianyun's eyes were truly opened this time.

In particular, the massive building in the city center is so large that even from the distant universe, one cannot see its entirety!

"This building must be at least 60 million kilometers long!" Mo Tianyun estimated.

Xi Yue laughed and said, "This isn't that big, is it? Compared to my house, this building isn't even a speck of dust!"

"Huh?" Mo Tianyun was instantly dumbfounded.

The building in front of us is at least 60 million kilometers tall, yet it's not even a speck of dust compared to Xi Yue's home? Just how big was Xi Yue's previous home?

It's outrageous just to think about!

"Let's go. Once we find the residence of Lord Canglan, we'll sneak in and use our mental energy to sense it. That should lead us to his treasure vault."

Xi Yue suggested.

"Does this count as stealing?" Mo Tianyun said with a self-deprecating smile.

Xi Yue shook her head: "What's this? Since you've already killed that Canglan Domain Lord, his things naturally belong to you! In the near future, the entire Canglan Star Cluster will have to be renamed!"

"Haha, that's true. Soon, the Azure Sky Cluster will be mine!"

Mo Tianyun looked around and smiled faintly.

The Lord of Canglan was the most powerful star domain-level life form in the Canglan Star Cluster, but he killed them all. It can be said that he is now the most powerful person in this star cluster!

Of course, Xi Yue is an exception.

Therefore, the Canglan Galaxy Cluster was naturally his for the taking, and taking over the entire Canglan Galaxy Cluster would be as easy as taking candy from a baby!

The top of the Azure Tower.

“Xi Yue, look at this door. There’s a gap there, and the shape of the gap is exactly the same as the rune key left behind by the Azure Mist Domain Lord!”

"This door must be a special device. If we force our way in, what's inside will be destroyed. This might be a way for Lord Canglan to protect his wealth. But it's a pity, what use is wealth if we lose our lives?"

Then, Mo Tianyun took out the huge rune key and inserted it into the gap in the door.

Boom! Boom! Boom!

The gates rang three times in succession, and all three gates, one inside and one outside, were opened simultaneously.

These three gates are to prevent others from damaging them and breaking in to take what's inside.

Lord Canglan probably never dreamed that one day he would be killed by someone in the Canglan Star Cluster, thereby obtaining his rune key, opening the door to the treasure vault, and openly taking away the wealth he had painstakingly accumulated over millions of years!

Yes, the wealth inside is the enormous wealth that Lord Canglan has painstakingly accumulated over millions of years!

The space inside the gate is surprisingly large. Although it looks small from the outside, once you step inside, you can feel the space expand tens of thousands of times!

This treasure trove could probably hold an entire star system!

This space is truly remarkable, created by an advanced civilization with incredibly sophisticated spatial technology!

Xi Yue's black and white pupils swept forward, revealing everything inside the treasure vault.

Then she described everything she had seen: "Most of them are energy crystals. Although there's nothing special about them, their sheer quantity makes them quite valuable!"

Just how numerous are these energy crystals?

Do you remember the white hole space in the universe that Mo Tianyun discovered in the ancestral land of alien beasts? It contained a large number of energy crystals.

The number of energy crystals here is at least ten thousand times the number of energy crystal blocks in the space of the cosmic white hole!

This is truly astonishing. Is this the wealth accumulated by advanced life forms in the universe?

Moreover, the Lord of Canglan Domain is not particularly powerful, yet his wealth is so astonishing!

In fact, if it weren't for the Zerg invasion, there would be even more energy crystals within this protected area. However, after the Zerg invasion, in order to fight against the Zerg, the number of energy crystals here is less than half of what it was at its peak!

In other words, the Azure Cloud Cluster consumed at least half of its energy crystals in order to deal with the invading Zerg!

So how did Lord Canglan obtain these enormous quantities of energy crystals?

Most of them were obtained by the Azure Sky Domain Lord through exploiting nearby star system-level civilizations.

Among them was a contribution from the Dylan Empire and the Northern Lippold Federation civilization!

"Huh!"

"Zerg crystal cores! And life crystals!"

Suddenly, Xi Yue exclaimed in delight.

It then disappeared from its original spot and reappeared near two mountain-like crystals emitting emerald green light and multicolored light.

Mo Tianyun also turned his head and looked over, and found that the pile of colorful crystals was the Zerg crystal core that he was familiar with.

The other pile of crystals emitting a bright green light must be the life crystals that Xi Yue mentioned.

"Tianyun, this is wonderful! The life energy I lost can finally be replenished a little! This brings me one step closer to returning to my peak strength!"

It was clear that Xiyue was very happy!

That was genuine happiness from the bottom of my heart.

Mo Tianyun was content as long as he saw her happy and joyful.

After all, who wouldn't want to see their loved ones and those who love them genuinely happy?

One after another, Mo Tianyun found many more mecha blueprints, mostly Star God combat mecha blueprints, with only a few Sky King combat mecha blueprints.

Within the treasure vault are 15 Star God battle mechs, 1695 World Destroyer battle mechs, and 16 Legendary battle mechs.

As for other lower-level combat mechs, there are none, because in the eyes of the Azure Domain Lord, those lower-level combat mechs are trash mechs.

Who would randomly stuff trash into their treasure trove?

However, none of these combat mechs were of any use to Mo Tianyun; he could only melt them all down to extract higher-grade materials.

Perhaps, it could also be rewarded to the Heavenly Cloud Emperor for his outstanding genetically evolved martial artists.

"Tianyun, Lieyang, come quick, come quick!"

Suddenly, Xi Yue sent a mental message.

The manifested spiritual voice seemed quite surprised.

Mo Tianyun and Lieyang, who had been lying in the same spot, both looked up at the same time and gazed into the distance.
