With such a strong monster physique, Bai Yuqi was not worried about being energized at all.

Because his living biological metal cells are like "nuclear batteries" that can grow and evolve, as long as they absorb enough energy, they can evolve from "nuclear batteries" to "nuclear power plants"!

According to Bai Yuqi's own estimates, after absorbing the Sun Essence of the Child of the No. 1 Sun, he would be able to advance to [Rank 8].

Then absorb the "Holy Spirit Body" of the four children of the sun to advance to [9th Order], followed by 16 [10th Order] and 64 [11th Order], which is enough to make him improve a lot by leaps and bounds, and bury a big step away from "achieving eternity and reaching the top"!

The only pity is that the remaining coffin of Xijin does not know where to go, or if you don't get together 100 bodies, there may be a big surprise, such as summoning the sun god?

After these amazing harvests, Bai Yuqi was not in a hurry to do anything else.

While absorbing and digesting the essence of the sun step by step, he stared at his subordinates to build Sun City and rock mussel farms, feed farms, energy storage pearl processing plants, giant high-energy regenerative rice planting greenhouses, and dark matter crystallization manufacturing plants.

With the completion of the Ashen City side, manpower was transferred to the Sun City side on a large scale.

The scene of tens of millions of people working in one area is really a bit spectacular.

And that's not even counting the huge Regenerated Heroic Legion, Spore Biocyborg Legion, and Undead Scourge Legion.

Therefore, even if Bai Yuqi was busy improving himself and didn't have the time to personally level the male city, Sun City was still built at a speed that was almost "rising from the ground".

The progress will be so fast, mainly because the infrastructure corps of [Tiangongmen] can become the reason why the formation can come to help after collectively installing the "Dark Crystal Shield Constant Temperature Protective Clothing".

Borrowing from the "isolation cloak" design of the sand witches, Bai Yuqi's alchemy workshop uses the accidental dark matter crystals to be cut, polished, and carved after simple cutting, polishing, and carving.

It can stimulate a layer of dark energy isolation shield to protect humans from the Datang time and space from the dark energy radiation that floods the world of Ertes.

At the same time, the protective clothing engraved with the constant temperature array can also protect the people of the Tang Dynasty from the high temperature climate of the Ertesian world.

As for maintaining the dark energy consumed by the Dark Energy Isolation Shield and the Thermostatic Circle, the "Dark Crystal Shield Thermostat Protective Suit" can be directly supplemented from the space of the Ethers World, which perfectly solves the problem of dimensional differences.

And to these [Tiangongmen] craftsmen who came to help, with the corresponding level of energy storage pearls, it perfectly solves the problem of low-level craftsmen lacking mana and not being able to release building spells on a large scale in a sustainable and large-scale manner, and it would be strange if the construction speed of Sun City has not been improved.

In addition to the construction of Sun City, the environmental renovation of the Death Sand Sea is also underway.

A large number of simplified and improved sand suction devices have been manufactured in batches by Yingzhou's construction and intelligent machinery factory.

After the analysis and cracking of the Tai Sui vortex, the original sandblasting function of the endless sandbox was abandoned.

Just pursuing the function of absorbing sand can greatly simplify the difficulty and production cost of production, and a large number of undead sand removal teams can be installed.

Yes, the lower undead, as an undead creature with little intelligence, are best suited for this kind of simple and boring work, and they don't feel bored anyway.

Coupled with the bones of various creatures in the sand sea, it is simply a sea of smoke.

After transferring Gu Aotian, the undead commander, he was busy studying and analyzing a large number of strange things, and simply handed over the right to use the negative energy half-plane to it.

In this way, Gu Aotian can take his army of undead to unleash a steady stream of [Undead Scourge] in the cleared desert, and transform these bones that have been buried in the sea of death sand for an unknown number of years into cheap labor such as low-level undead.

All Sun City has to do here is to produce a large number of sand suction equipment for these low-level undead, and then throw them into the desert and leave them alone.

These cannon fodder skeletons who don't need to eat, drink, or get tired will work 24 hours a day, all year round, and they don't need to be paid.

As a result, the sand layer around Sun City was quickly cleared, making the area belonging to Sun City larger and larger, and the sandstorm receded farther and farther.

Vast amounts of mineral and biological resources were exposed, collected by the undead scavengers and transported back to Sun City.

Don't forget, the predecessor of the Sea of Death Sand was actually the sea of the world of Aetherus.

Although the sea has dried up, the remains of the creatures that originally lived in the sea have been fossilized after thousands of years, as long as they have not been weathered, and there are many rare arcane materials.

Therefore, the reason why so many high-level spellcasters like to travel in the plane is because it is so convenient to plunder resources in different planes.

Bai Yuqi, who sits on the two major planes of the Tang Dynasty and the Ertes world, has initially achieved resource self-sufficiency, and no longer has to worry about the lack of this and that when studying the knowledge system of the arcane civilization.

Just after Bai Yuqi absorbed the Sun Essence of the Five Sun Sons twice, and naturally promoted himself to the [9th Order].

As they were about to take a look at the sunken lava plateau of the Holy Spirit Sky Island, which was mentioned in the remnants of the Sun's thoughts, and could be teleported in the sky, some hidden forces in the world of Ertes finally couldn't help but move.

Although inheriting the essence of the sun of the son of the sun is used to improve himself.

But Bai Yuqi really didn't pay attention to the remnants of the natural sect that were said to have escaped to the eastern asphalt swamps and the withered forests of the south.

In the process of developing the world of Etes, if you encounter it, you will deal with it, and if you don't encounter it, forget it.

After all, they are all 12,000 years of old grievances, when will they be retribution?

The two sides only have different ideas to save the world of Etes, and their butts are not clean, so why bother to kill them all?

The main thing is...... What the hell?

What Bai Yuqi didn't expect was that he restarted the Four Elements Circle and opened the Sun Tomb.

It actually touched the nerves of the remnants of the natural sect that had disappeared for 12,000 years, and it was the two remnants who coincidentally re-embarked on the path of revenge, gathering two armies to kill in the direction of the Ash Wasteland!

Although with the conditions of the world of Aetherus, the remnants of these two natural sects still have a long way to climb slowly if they want to reach Ash City, Bai Yuqi had to interrupt his plan to go to the northern lava plateau and return to Ash City to take control.
