Tianyan City, Cave No. 2186, Tianxingjia.

Xiao Yu looked at the jade bottle, which was like a huge mountain range of minerals in the universe.
"The materials of 250 million cosmic sands, among which the materials specially used to refine the Eternal True God-level mechanical secret treasures are enough to refine at least five individual secret treasures, or refine a legion-level mechanical secret treasure." Xiao Yu looked at Xiao Shu next to him and said, "What do you think I should choose?"

"Although legion-level mechanical secret treasures are difficult to refine, each one is extremely powerful and valuable, starting at at least tens of millions of cosmic sands." Xiao Shu has been working diligently during this period.

While shopping, eating, drinking and having fun, I also learned more about the common sense of the continent of origin.

"If refining a single secret treasure can bring three times the profit, then refining a large mechanical secret treasure can bring ten times the profit." Xiao Yu thought for a while and made up his mind, "I will refine a Phantom Fire Pterosaur."

A mechanical secret treasure of the level of the Phantom Fire Pterosaur is worth between 1500 million and 1800 million cosmic sands, and is often in short supply, so it is needed by major cities.

"Xiao Shu, here are 1 cosmic sands. I'll give them to you as pocket money. During this time, I will be in seclusion for cultivation, and you can move freely." Xiao Yu reminded him, and with a wave of his hand, a green jade bottle floated in the air, "Remember, don't cause trouble for me."

"Don't worry, master!" Xiao Shu happily took the green jade bottle containing 1 grains of cosmic sand.

Xiao Yu immediately turned around and entered the underground hall of the cave. As soon as he entered, the layers of mechanisms in the underground hall opened and the formation was sealed.

Xiao Yu stepped into the Three Thousand World-Fighting Boat and entered the cultivation space.

As soon as he entered the training space, he put away the incarnation of divine power and then took out various tools used to refine treasures.

With a thought, the Chaos Divine Power changed and took the form of Chaos Fire. Xiao Yu then began his long career of refining secret treasures.

It would take tens of millions of years for Xiao Yu, who is now at the Chaos Domination Realm, to create an Eternal True God-level treasure.

"Boom!" "Boom!" "Boom!"

Various tools continuously bombard the refining materials, quickly processing each piece of material into a special style. At the same time, the unique skills of refining are used to stimulate the performance of the material itself.

"All the materials have been refined, and their properties have been stimulated. Now it's just right to use the formation to combine these materials and bring out stronger effects." Xiao Yu wiped his sweat.

Xiao Yu's mind moved, and hundreds of millions of precious parts were distributed in the void according to the order of movement. Afterwards, Xiao Yu used the power of chaos to carve out a series of secret techniques.

This step is crucial. For a secret treasure, success or failure depends on this one move.

After a long time, Xiao Yu stopped his actions, and in the void, the parts of the treasures automatically combined into a strange treasure, the shape of which was exactly the same as that of the Phantom Fire Pterosaur.

"This Phantom Fire Pterosaur is at least a top-grade item. It should be able to sell for 1800 million cosmic sands." Xiao Yu's Chaos Divine Power swept over it, and the quality of this treasure was clear. Then Xiao Yu looked at the remaining materials next to it, "As for these materials, they should be able to refine 50 ordinary Eternal True God-level weapons."

Immediately, Xiao Yu picked up the materials one by one and continued to refine them.

This time, it did not take Xiao Yu much time to refine one ordinary eternal-level treasure. It took less than a thousand days to refine all fifty eternal true god-level treasures.

"Haha, they are all top-grade. Each one is worth at least 1 grains of cosmic sand." Xiao Yu glanced at the Eternal True God-level weapons.

No matter whether it is a sword, hammer, shield, divine tower or anything else, the aura emitted by each item is extremely strong among eternal-level treasures.

With a wave of his hand, Xiao Yu collected the treasures one by one, then stood up and took a step away from the Three Thousand World-Fighting Boat.

The Three Thousand World-Cutting Boats were put away, and then the formations in the underground palace were closed layer by layer, and Xiao Yu left the underground palace. The Chaos Divine Power swept through the cave, but did not find Xiao Shu. Xiao Yu thought to himself, "Haha, this guy must have gone out to eat, drink and have fun."

"The end of the Chaos Ruins is the Chaos Layer. Now that I have become the Lord of Chaos, I will go to the Chaos Layer to take a look." Xiao Yu thought.

Xiao Yu left the cave at once, and with an intention, he continued to go upstream along the ruins of chaos. At first, the surroundings were still very narrow, but the more he flew upstream, the wider it became, until it was completely boundless.

"This is the chaos layer." Xiao Yu looked at the boundless and extremely dense power of chaos.

Xiao Yu looked around and felt that the chaos layer was like a boundless ocean, the power of chaos was the sea water, and he was a giant ship.

Xiao Yu soared in the endless power of chaos, looking at the dazzling and golden chaos law, and the slightly silvery chaos law.

These are all the laws of chaos, but they appear differently, such as chaos gold, chaos fire, chaos water, etc.

Suddenly, a blue light emerged from the chaotic airflow and flew straight towards Xiao Yu.

"Oh?" Xiao Yu grabbed the blue light with his hand. The blue light kept struggling in vain in Xiao Yu's palm.

"This is a creature from the Chaos Layer." Xiao Yu looked at his palm. What he had caught before was a blue bug.

The surface of the shell is like blue glass, and it looks very small, but its struggling strength is very strong, three times stronger than Qi Hu's, but it still has not reached the strength of the Chaos Realm.

It is said that in the entire Chaos Layer, all creatures that have reached the strength of Chaos Realm have been captured alive.

"Let me see what you are made of." Xiao Yu exerted a little force with his palm and crushed its divine body. The body broke into dozens of pieces, each of which was still struggling to merge into one.

"Tenacious vitality!" Xiao Yu's divine power penetrated the broken parts and observed carefully. It was just an extremely ordinary Chaos Layer creature.

As the days passed, Xiao Yu continued to go deeper into the Chaos Layer. He had also encountered attacks from some Chaos Layer creatures, but they were all ordinary creatures and had no reference value for his cultivation of the Great Dao of Origin.

"Whoosh!"

Suddenly, a silver-white chaotic creature, emitting an endless cold aura and like an ancient phoenix, suddenly appeared and then bombarded Xiao Yu directly.

"The ancient ice phoenix is ​​an extremely rare creature in the Chaos Layer. I don't know if I am particularly lucky or unlucky." Xiao Yu said inwardly.

This ancient ice phoenix is ​​also an extremely powerful creature in the Chaos Realm and is extremely difficult to deal with.

"boom!"

Thirty-six huge silver lights appeared out of thin air in the chaotic layer, drawing lines of silk that surrounded the ancient ice phoenix. At the same time, one end of the silk thread turned into a silver knife light, a silver sword, or a silver cone, and blasted towards Xiao Yu.

The speed was extremely fast, and one attack after another directly bombarded Wu Shenjia, emitting a devastating shock wave, and Xiao Yu continued to fly backwards.

"The destruction of the origin of life." Xiao Yu felt the powerful attack of the ancient ice phoenix and felt the branches of the origin of life contained in it. (End of this chapter)
