With Zhang Ruochen's unremitting efforts, the inner space of the space ring was finally expanded to twelve cubic meters, which was equivalent to the size of a small house.

"Wow!"

On the surface of the space ring, a flash of light flashes, and the inner space is completely supported to form an independent space.

"With my current cultivation level, I can only make the inner space of the space ring reach twelve cubic meters, and it cannot be larger."

Although the twelve cubic meters are not large, it is enough for ordinary warriors.

By the future, Zhang Ruochen's cultivation level will naturally be able to refine a ring with a larger space.

Burning inscriptions is just the first step.

Next is the second step, refining the ring.

Zhang Ruochen purchased a seventh-level true martial arts treasure refining furnace from Qingxuan Pavilion to refine a space ring. Under the tempering of flames, the inner space in the ring is completely stable and becomes a true martial arts treasure.

He put the space ring into the refining furnace, and then placed a fire-attributed spirit crystal under the refining furnace.

"Chichi!"

Under the urging of Zhang Ruochen's true energy, the fire-attributed spirit crystal began to burn.

Once the spirit crystal is burned, Zhang Ruochen only needs to control the strength of the flame. When a strong flame is needed, Zhang Ruochen will inject the true energy into the spirit crystal, and the spirit crystal will naturally burn more vigorously.

Zhang Ruochen sat cross-legged under the refining furnace, summoned the wooden picture of the Heavenly God floating in the Qi Lake, and rolled the scroll flat in front of him.

He stretched out a palm and pressed it on the surface of the scroll, injecting true energy into the scroll, and summoning Xiao Hei out.

A black light flashed, and a black giant cat appeared in front of Zhang Ruochen.

Xiao Hei's body was round, his tail was raised, and his eyes were like two round black crystals. He said, "Young man, have you learned all the eight basic space inscriptions?"

Zhang Ruochen nodded and said, "But I always feel that something is missing from the space ring?"

Little Black Doom: "Space rings are just the most basic space treasures. The space rings you refine are the foundations of the basics."

Zhang Ruochen said: "What do you say?"

Xiaomiao said: "The space ring you have refined lacks the main inscription. Once the space ring is lost, anyone can open your space ring and take away the treasures you stored in it."

Zhang Ruochen nodded and said, "What else?"

Little Black Dao: "The space ring refined by the Holy Monk Sumeru back then can not only be used for storage, but also launch attack power and display defense power."

"Can you also burn attack inscriptions and defense inscriptions on the space ring?" Zhang Ruochen's eyes lit up.

"That's certain."

Xiao Hei continued: "As long as you have high attainments on the inscriptions, you can also burn hidden inscriptions on the space ring. As long as you burn hidden inscriptions, others cannot see your ring on your hand, so you will not be afraid that others will covet your space ring."

Then, Xiao Hei said: "It's just that the main inscription pattern is recognized, and the hidden inscription pattern are all intermediate inscription patterns, which are quite complex. You can only burn it as long as your mental power reaches level 30 or above. Moreover, even if your mental power reaches level 30 or above, it requires a lot of learning and practice. After all, space inscription patterns are more difficult and more complicated than other inscription patterns."

Zhang Ruochen opened the fourth page of the Secret Book of Time and Space, and recorded sixteen intermediate space inscriptions.

Recognizing the main inscription and hiding the inscription are one of them.

In addition, there are also offensive inscriptions and defensive inscriptions.

The simplest intermediate inscriptions to recognize the main inscription is more than ten times more complicated than the sheet inscription and shrink inscription.

With Zhang Ruochen's current cultivation level, it is definitely not easy to portray the inscription of the master recognition.

"My mental power is above the 30th level. I have reached the standard of portraying intermediate inscriptions. As long as I practice hard, I will definitely be able to portray the main inscription."

Zhang Ruochen carefully observed the inscription of the master and kept it in mind. Then he started practicing on the spiritual paper.

About an hour later, an abnormal sound occurred in the refining furnace.

The space ring was refined successfully!

Zhang Ruochen couldn't wait to take the space ring out of the refining furnace. He put it in his palm and looked at it carefully. A smile appeared on the corner of his mouth: "A space ring with only one cubic meter of inner space can be sold for 100,000 silver coins. The inner space of this space ring is more than ten times larger than that one. What price can it be sold?"

Zhang Ruochen did not wait to sell the space ring because he did not lack silver coins at all now. There was no need to be so anxious.

As long as the first one is successfully refined, there will naturally be more space rings continuously.

"A month later, it will be the time for the entrance examination of Wushi Academy. We will strive to improve our strength within one month."

In one month, it is too difficult to practice from the early stage of Xuanji Realm to the middle stage of Xuanji Realm.

Since that's the case, then start practicing the space field.

Zhang Ruochen turned the secret scriptures of time and space to the third page and began to study the cultivation methods of the "space field" wholeheartedly.

The so-called space domain is to use the martial souls of time and space, and with one's own body as the center, forming a martial arts space independent of the outside world. In the space domain, everything is decided by Zhang Ruochen because he is the master of the domain.

Once you successfully practice the space field, Zhang Ruochen's combat power will be increased by at least three times or even more powerful.

Originally, only by reaching the realm of Heaven can Zhang Ruochen cultivate the space realm. However, Zhang Ruochen's soul is comparable to a warrior in the realm of Heaven, and he has opened up his soul veins, so he can naturally cultivate the space realm in advance.

Time passes by rapidly.

In one month outside, three months inside the inner space of the space-time crystal.

For three months, Zhang Ruochen has spent most of his time practicing the space field. Finally, the night before leaving the palace, he successfully practiced the space field.

"Space realm!"

Zhang Ruochen sat cross-legged in the room, using his soul veins to mobilize his martial soul and hang behind him.

The martial soul mobilizes the spiritual energy of heaven and earth and condenses into the power of space. With Zhang Ruochen's body as the center, a spherical space field covering a radius of ten meters is formed.

Zhang Ruochen was like being wrapped in the center of a huge white ball, and everything in the ball was under his control.

"rise!"

Zhang Ruochen raised his arm slightly, and a red copper lampstand three meters away slowly flew up and floated in the air.

"Bang!"

Suddenly, the lampstand fell to the ground, the flames went out, and the lamp oil splashed all over the ground.

The space domain also shattered and disappeared.

"The space field I have built now is still too fragile and must continue to be cultivated and consolidated. Moreover, I feel that my space field still has the power of lightning. Has the thunder and lightning spirit of my previous life not completely disappeared?"

Zhang Ruochen once again supported the space domain. After careful observation, he found that there were a trace of tiny lightning and lightning flowing in the space domain.

At this moment, a flying mosquito broke into the space field and flew towards Zhang Ruochen.

Zhang Ruochen smiled slightly, and thoughts moved in his mind.

"Bang!"

A ray of lightning condensed from the void, like a white sky knife, slashing the back of the floater, slashing the floater into ashes.

Zhang Ruochen discovered another wonderful thing, as long as he is in the space domain, his eyesight and ear strength will be enhanced several times, and he can clearly see the thin scales on the wings of the floaters and hear the subtle sound of the wind.

Is this the beauty of the space realm?

"As long as the Secret Book of Time and Space is recorded, the space field is really powerful. I have only now discovered less than one-tenth of the space field."

Although Zhang Ruochen really wants to continue practicing and continue to explore more wonders in the space field.

However, tomorrow he will leave the palace and go to the Wushi Academy. I don’t know how long it will take to wait to come back. Before leaving, he naturally wanted to have a good gathering with Concubine Lin.

Since Zhang Ruochen showed strong cultivation talent, Concubine Lin's status in the palace has continued to rise, and the number of palace maids and eunuchs around him has gradually increased, and the entire Yushu Palace has become lively.

"Chen'er. It is said that the Wu City Academy was built in Tianmo Ridge, where wild beasts are rampant and it is quite dangerous. You have to be careful!" Lin Fei took Zhang Ruochen's hand and was reluctant to let Zhang Ruochen leave.

However, she also knew that when the child grows up, he will sooner or later leave his parents' arms and face the wind and rain and challenges outside independently.

Zhang Ruochen smiled and said, "Mom, you're worried too much! The Wushi Academy is just built on the periphery of Tianmo Ridge, so it won't be too dangerous. Besides, there are many masters of Wushi Academy, and the wild beasts in Tianmo Ridge dare not attack Wushi Academy."

Concubine Lin nodded and then said, "It is said that you and Ning Shan have become enemies again! Alas! After all, she is your cousin. No matter how big the mistake you make in the future, you still remember to spare her life."

Zhang Ruochen's face became serious and he said, "Is this what the old man from the Lin family asked you to tell me?"

After taking the spirit flesh, Lin Fei looked younger and more beautiful, and said softly: "Chen'er! Your grandfather actually cares about you very much, but he can't help but have some things."

Zhang Ruochen nodded and said, "Mom, I promise you that as long as the Lin family members don't come to provoke me again, I will naturally not deal with them."

Concubine Lin nodded deeply, and was truly proud of her son. He really grew up! The Wushi Academy will be a bigger stage for him.

As long as you achieve outstanding achievements in the Wushi Academy, those who once looked down on their mother and son so much would naturally shut up obediently.

Then, Zhang Ruochen took out a thousand spiritual crystals and handed them to Concubine Lin, asking Concubine Lin to send them to the Lin Mansion and handed them to the Lin family.

One thousand spirit crystals are equivalent to one million silver coins.

Zhang Ruochen asked Concubine Lin to send a million silver coins to the Lin family. In fact, it was also obvious that Concubine Lin still had a deep affection for the Lin family. If they could repair their relationship through this opportunity, it would be the best thing to do.

If the Lin family still had the same attitude as before, and both sides became enemies in the future, Zhang Ruochen would not show mercy.

The next day, the sky was slightly bright, and under the escort of a team of imperial guards, Zhang Ruochen boarded the ancient chariot of the Lingma.

Princess Nine is tall, graceful and beautiful. She stood on the stairs and said loudly: "Brother Nine, I will also practice to the Xuanji Realm as soon as possible. At that time, I will definitely go to the Wu City Academy to find you."

Zhang Ruochen sat on the Lingma and smiled and said, "Sister Jiu, I'll be waiting for you in the Wu City Academy!"
Chapter completed!
