Time passed slowly.

About half an hour later, Chen Xuan completed the initial improvement.

But after a while, Chen Xuan sighed slowly.

"It seems that loving me is too simple as I thought before. It's still not enough. If you want to improve the level of the prairie prairie sword, I'm afraid I have to understand it."

Chen Xuan said secretly.

However, he also knew that this time he was just trying, and Chen Xuan had not given up hope of improving the power of the prairie prairie sword.

In the following time, Chen Xuan began to continuously try to integrate the energy in the prairie fire sword to see if he could separate the power from these spiritual materials and then integrate it into the prairie fire sword.

After his constant attempts and the loss of a lot of spiritual materials, Chen Xuan finally succeeded.

Looking at the prairie fire sword in the alchemy furnace, Chen Xuan's face was full of excitement.

Finally, the seventh-level immortal weapon was refined. This was the seventh-level immortal weapon that Chen Xuan personally upgraded. It can be clearly felt that the power of the prairie fire sword has increased a lot.

But there was no complete transformation, so Chen Xuan now knew that it was not that easy to completely enhance the power of the prairie prairie sword.

"Although it is a seventh-level immortal weapon, it is also a breakthrough for me."

The prairie fire sword was upgraded to a seventh-level immortal weapon, and the improvement for Chen Xuan was very obvious.

And now his understanding of swordsmanship has advanced further, and Chen Xuan can now be called an immortal-level swordsman.

However, among the fifth-level immortals, Chen Xuan's understanding of swordsmanship can only be regarded as low-level, not very superb.

But the inheritance of swordsmanship was deeply imprinted in his mind.

"Lord Chen Xuan, I am very gratified. Not only have I gained a deeper understanding of swordsmanship, but I have also improved the level of the prairie fire sword."

The little firebird said with a smile.

"Although it has been promoted to a seventh-level immortal weapon, it is not enough for me. A ninth-level seventh-level immortal weapon, or even a seventh-level immortal weapon, if the prairie prairie sword can be upgraded to this level, even if it is faced with

With stronger enemies, I have a higher chance of winning. In addition, my understanding of swordsmanship has really helped me a lot."

Chen Xuan held the sword tightly in his hand and said secretly.

However, Chen Xuan also knew very well in his heart that it was impossible to reach the level of refining a seventh-level immortal weapon in a short period of time.

Although he is a swordsman, it is very difficult to improve his understanding of swordsmanship. Many people spend their entire lives unable to improve too much. Chen Xuan can achieve this step now and it is already very good.

"Anyway, there are still six years left until the ruins are closed. You can also practice during this process."

Chen Xuan said slowly: "I will strive to be promoted to a ninth-grade and seventh-order immortal weapon when I leave the Blood Kong Ruins. By that time, my understanding of swordsmanship will become even more profound."

"I will be practicing here for a long time in the future. You have to be careful. We have provoked the Yunxian Huajian Sect. This Song Qing will definitely kill us."

Chen Xuan said to the little fire bird.

The little fire bird sneered and said: "Master Chen Xuan, don't worry, I am not the kind of person who has no eyesight. If I find them, I will definitely not take the initiative to provoke them."

"Very good. During the time when I am practicing in seclusion, you must be careful. If anything happens, call me directly. Don't be tempted to fight when you are in danger."

Chen Xuan said slowly.

The little firebird nodded, said nothing more, and then turned around and left.

Since Chen Xuan wanted to practice in seclusion here, the little fire bird wouldn't stay here forever, so he simply left here.

However, at this moment, Chen Xuan completely covered the entire secret cave with formations, making it impossible for any breath to escape from here.
