When he returned to the cave, Cui Chen did not immediately set up an array to refine the weapons. Instead, he went to the quiet room and took out the half-foot-long thunderwood willow branch to study.

This thing is only as thick as a thumb, and its color is unusually emerald green, but there are some small whirlpool-like lines on its surface, making it look like one is immersed in it.

Cui Chen already knew the secret of this tree, but holding it in his hand, he couldn't help but slowly pour magic power into the branches.

As expected, as soon as a little bit of mana was injected, the branches trembled slightly, and a rebound force suddenly emerged, rebounding the mana out.

Then, Cui Chen tried to control the vitality of heaven and earth to inject it, and the result was the same as injecting mana.

This branch is like a stone girl, with no holes to penetrate.

After Cui Chen thought for a while, he tried to communicate with the innate divine talisman in the sea of ​​consciousness. As his cultivation level increased, he could barely activate the talisman's power.

But the results showed that there was not much innate purple energy in this willow branch.

Looking at the thunder marks on his body, Cui Chen had a guess in his mind that it should be a trace of the law of thunder manifested.

It would be too much of a waste to slice it up and learn some magic tricks.

If they wait until they are combined, they might be able to comprehend a trace of the law of thunder.

With this thought in mind, he took out an empty jade box, put the thunderwood willow branch in it, and affixed the sealing talisman to preserve it.

Then he walked out of the quiet room, came to the weapon refining room, and started refining the weapons.

He first copied several spiritual treasures designed by other weapon refiners. The refining methods of these spiritual treasures were already very perfect. Cui Chen only needed to refine them step by step.

During this process, Cui Chen carefully observed every change. From the fusion of various spiritual materials to the infusion of heaven and earth energy into it to form a spiritual treasure restriction...

After that, Cui Chen began to design Lingbao.

This process is undoubtedly extremely complicated. The materials, spiritual treasure restrictions, and formations need to be perfectly matched.

Otherwise, just like the Xuan Ling Bead, it was obviously designed according to the middle grade Ling Bao, but there was a slight disharmony between the restrictions and the materials, and the grade dropped to a low grade Ling Bao.

When Cui Chen was refining the turtle and snake two-phase shield, he was worried about conflicts, so he only dared to add Taiyi platinum to increase the hardness, and the prohibitions were also very conservative.

Only under such circumstances can it be refined into a top-grade spiritual treasure.

Without the material bonus this time, Cui Chen's failure rate can be imagined. The wasted spiritual materials were enough to bankrupt several monks in the Void Refining Stage.

Fortunately, Cui Chen's net worth is rich enough, which can support Cui Chen's research.

Slowly, Cui Chen gradually found the trick, and each finished product was born in Cui Chen's hands. However, due to material limitations, he still could not refine the top-grade Lingbaolai.

Cui Chen kept a few of these exquisite items and sold the rest for blood.

Among them, the low-grade spiritual treasures were sent to Chenxi Shop to be processed by the succubus in exchange for various spiritual materials; the medium-grade spiritual treasures were naturally sent to Taixuan Palace and Longdong helped to auction them, for mutual benefit and win-win results.

In this way, Cui Chen's reputation gradually spread. Many monks with top-quality materials would come here to ask Cui Chen to help refine weapons. The reward was naturally very generous.

Cui Chen will also choose the materials he likes and take them, taking the opportunity to improve his skills in weapon refining.

Time flies, and one hundred and sixty years pass by leisurely.

Cui Chen finally achieved "knowing what it is and why it is so". Only with this skill in weapon refining can he be called the master of weapon refining.

And Cui Chen's cultivation level has not fallen behind. Relying on the tree of spiritual eyes and the occasional collection of spiritual herbs to make pills, Cui Chen's cultivation level has also steadily improved.

A year ago, he reached the peak of the middle stage of refining the void.

Then he put down whatever he was doing and went into seclusion.

On this day, the door of the quiet room opened with a bang, and Cui Chen strode out with a smile on his face. Judging from the strong pressure around him, it was obvious that he had succeeded in breaking through.

He officially became a late stage cultivator of the Void Refining Stage. And it is worth mentioning that the moment Cui Chen broke through the late stage of the Void Refining stage, his soul naturally underwent a qualitative change, reaching the level of the early stage of integration.

"Congratulations, master, for your great improvement!" As if well-rehearsed, the two voices merged into one voice.

Under Cui Chen's training, Hongyu and Xie Zhi successively broke through the refining stage. Their appearance also increased from eleven or twelve years old to fifteen or sixteen years old.

"Huh? Why don't you see Xiao Yin?"

Cui Chen didn't see the psychic puppet and immediately asked.

"Hehe! There is good news, we are just about to tell the master!" Hongyu said with a sweet smile. She always smiles and has a gentle temperament, like a lady.

"What good news? Come and tell me!"

"Han Li has come to Tianyuan City, and is now being led by Xiao Yin to visit the medicine garden!" The person who spoke now was Xie Zhi. Compared to Hong Yu, she looked like a female general on the battlefield, and she was also wearing a purple battle suit.

A, majestic. He is also straightforward in his actions and speech, and will not show off like Hongyu.

"oh?"

Cui Chen was overjoyed, and his spiritual consciousness spread out, instantly covering the entire spiritual land. Sure enough, he found Han Li and Xiao Yin in a medicine garden.

Han Li was still wearing a green robe, and his face did not change at all.

He was looking at every elixir in the medicine garden with great interest, his eyes filled with passion.

Little Yinze stood aside like a wooden person and didn't speak. His intelligence is now the same as that of an ordinary human teenager, but his personality is more rigid and dull, and he doesn't like to talk. He is often bossed around by Hongyu and Xie Zhi.

Gotta go round and round.

Han Li knelt down, holding a leaf of an elixir with one hand and gently gliding over the veins of the leaf with the other, as if caressing a lover's back.

Suddenly, Han Li felt a vast coercion, as if this world was dominated by someone.

He himself is like a small boat on the vast ocean, extremely small.

"this……"

Han Li's body suddenly tensed up, and he stood up, looking solemnly at the top of his head.

At this moment, a familiar voice sounded in his ears, "My father is out of confinement, come to the cave to see me!"

"call!"

"It's my father-in-law!"

Han Li let out a long breath, turned around and flew towards the cave with Xiao Yin.

After a meal, the two entered the cave and saw Cui Chen sitting on a chair, Hong Yu was kneeling beside him making tea, and Xie Zhi was standing behind Cui Chen with his arms folded, staring at him.

Han Li showed no expression at all.

"My son-in-law pays homage to his father-in-law, and I wish him to enter the immortal world soon and live as long as heaven!"

Han Li sensed Cui Chen's gaze, and he suddenly seemed naked without any secrets, which made him even more frightened.

From the mouth of the Qingming Guard who received him, he already knew that Cui Chen was a Void Refining Stage monk, but now he saw that he was obviously much stronger than the several Void Refining Stage monks he had seen in Tianyuan City.

I'm afraid it's not as simple as being a newbie.

When Cui Chen saw Han Li's restrained expression, he couldn't help but smile and joked: "I didn't expect that after three hundred years, you would learn to be glib. Well, don't be nervous in front of your father, sit down and drink tea! Hongyu's tea skills are also good.

of."

Cui Chen's words seemed to have some kind of magic power, and Han Li's fluctuating mood calmed down immediately.
Chapter completed!
