In the refining room, the fire in the center of the earth is burning, and a refining furnace is suspended above the fire in the center of the earth.

Xiang Chen took out the purchased materials and put them into his Vientiane Infinite Heaven Refining Furnace in proportion.

The Wanxiang Wuji Heavenly Smelting Furnace absorbed the power of the fire from the center of the earth and began to smelt the materials inside. When the materials such as the Sun God Iron were smelted into a liquid state of a specific temperature, he used the essence and blood as ink to condense the inscription inside the liquid.

Finally, all the materials were smelted together, and the Tao Ancestor's magic technique of Thousand Machines and Hundreds of Refinements was used to start refining the alloy and refining the magic weapon.

A full fifty years have passed inside the Wanxiang Wuji Heaven Refining Furnace, and only one year has passed outside.

He arranged a space-time array at the level of Heaven and Earth in his All-Seeing Infinite Heaven Refining Furnace, which can increase the time-space difference to fifty times, but it consumes precious Hongmeng Amethyst that has the attributes of time and space.

Fifty years passed in the Heaven Refining Furnace, and Qi suddenly erupted. A large amount of immortal energy from the outside world gathered into the Heaven Refining Furnace, and a sword was condensed inside, a golden divine sword that emitted the rays of the sun.

An immortal artifact-level sword!

Xiang Chen looked at the sword and nodded with satisfaction, "It is indeed Dao Ancestor's weapon refining technique. It's really awesome. The speed of refining the sword is more than ten times faster than my own weapon refining technique. The quality is nothing to say."

"But we still need to refine more than 300 handles. This is not a small amount of work. Fortunately, I have many souls. Now I am familiar with it, and I can refine more than 20 handles at the same time."

Xiang Chen muttered to himself, then continued to refine the weapons, and at the same time began to sacrifice more than twenty immortal artifacts.

Another year later, he had more than twenty immortal artifacts and swords in his hands, each sword containing a different attribute of star power.

Twenty years later.

In the Wanxiang Wuji Heaven Refining Furnace, Xiang Chen looked at the three hundred and sixty-five immortal artifacts suspended with a smile on his face.

All the three hundred and sixty-five Zhoutian Divine Swords needed to practice the Zhoutian Sword Formation were refined.

He burst out with powerful mental power, and his mental power divided into 365 channels and penetrated into these Zhoutian Divine Swords. The Zhoutian Divine Swords began to rotate slowly and began to form formations.

After a moment, Xiang Chen spat out a mouthful of blood, his head hurt violently, and the sword formation immediately collapsed.

"I also want to eat it and become a big fat man——"

Xiang Chen smiled bitterly, and then gave up the idea of ​​using the three hundred and sixty-five swords directly, and began to control the thirty-six formations to try to get started.

The entry-level difficulty level was extremely easy for him. He laid out the entry-level sword formation on the first try, and then he became familiar with it and accelerated the layout of the entry-level sword formation.

This sword formation, even for beginners, can exert its power at the early stage of the realm of Fa Tian Xiang Di.

The sword formation is complete, and the blow issued by all the Zhou Tian Divine Swords is comparable to the strike of a powerful person in the eternal realm of heaven and earth!

In the blink of an eye, a hundred years passed quickly, and the day of the selection of the Holy Son soon came.

Dongsu Dragon Palace.

In front of the gate of the Dragon Palace, people participating in the selection of the Holy Son gathered at the gate of the Dragon Palace one after another, waiting for the summons.
