Opening the system interface, Xu Feng carefully checked it, and soon his eyes fell on the hand that disassembled the imperial weapon long sword;

"One hundred grams of source material, a piece of Chaos Magic Crystal Iron, a Chaos Magic Fire Crystal, a fragment of the Chaos God-killing Formation, and an unknown emperor-level legacy!"

"One hundred grams of source material?" Xu Feng's eyes lit up. The emperor-level puppet beast in the Tianhe Water Palace could finally be repaired. Although it required twenty-eight Tianhe navy soldiers to control it at the same time, a puppet beast that could exert emperor-level strength was an irresistible temptation for Xu Feng now!

In addition to the source material, two pieces of Chaos Grade materials were also obtained. However, there was no forger in the entire upper realm who could use Chaos Grade materials to forge spiritual treasures. You know, Chaos Grade materials are all for forging imperial weapons. If there really was a forger who could forge an imperial weapon, it would be impossible for a broken imperial weapon long sword to attract so many great elders of the Baimai Xianzong to pursue it. "These two pieces of Chaos Grade materials can only be put in the bottom of the box now!" Xu Feng shook his head and sighed, looking at the next item; the fragment of the Chaos God-killing Formation! "It turned out to be a formation, and it was a Chaos Grade formation..." Xu Feng's face showed a surprised smile.

"Fragments, haha, there are no fragments in my hand!" Xu Feng cast the creation spell on the fragment of the Chaos God-killing Formation in the parcel column. After a while, he consumed 30 grams of source material and restored the Chaos God-killing Formation diagram to its original state! [You have obtained a complete Chaos God-killing Formation diagram. The system detects that you have a Dao-level formation, the Zhoutian Star Formation! You have the following two choices: Option 1, combine the Chaos God-killing Formation diagram and the Zhoutian Star Formation you have mastered into one, and merge them into a new formation; Option 2, find four Chaos Extreme Spiritual Treasures and integrate them into the Chaos God-killing Formation diagram. According to the properties of the integrated spiritual treasures, the Chaos God-killing Formation diagram will be upgraded to a new formation diagram! ]

"A complete Chaos God-killing Formation diagram, two choices..." A solemn look appeared on Xu Feng's face.

The Chaos God-killing Formation Diagram, just by hearing the name, you know that it is a Chaos-level formation. Although the Zhoutian Star Fighting Formation has also been upgraded by Xu Feng, it is only the lower grade of the Great Dao at most. It is very powerful against the cultivators of the King level, but it is very difficult to deal with the Emperor-level strongmen. Before, although Ouyang Ling relied on an imperial weapon to forcibly upgrade his cultivation level to the peak of the Emperor level, under the Zhoutian Star Fighting Formation, he still insisted on resisting 108 star beams before breaking up his body, and he was not completely killed. Even in the attack of the star beams, Ouyang Ling absorbed enough star power and broke through in the battle, upgrading the bloodline of the undead. This is a bit funny! If the Chaos God-killing Formation Diagram and the Zhoutian Star Fighting Formation can be integrated, the power will definitely not be a little bit. Although I don’t know what formation it will become after the fusion, the grade is definitely Chaos-level!

As for option 2, after reading it, what came to Xu Feng's mind was a formation, the Immortal Execution Formation! "If I can find four emperor-grade long swords and integrate them with the Chaos God-Slaying Formation, I wonder if I can make the legendary Immortal Execution Sword Formation reappear in the world!" Xu Feng couldn't help but fantasize in his heart.

If the Zhuxian Sword Formation claims to be the second best, I am afraid that no other formation would dare to claim to be the best. It is said that when Master Tongtian performed the Zhuxian Sword Formation, it could not be broken by less than four saints of the same realm. If Xu Feng could really replicate the Zhuxian Sword Formation, when he becomes an emperor-level powerhouse, he would definitely be invincible in the same level when facing emperor-level powerhouses of the same realm!

There are two choices. Choice one can gain benefits immediately, and even if Xu Feng becomes an emperor-level warrior in the future, the Chaos Extreme Formation will never become obsolete. Choice two focuses on the benefits in the later period. If the four emperor weapons can be integrated, even if it cannot be evolved into the Zhuxian Sword Formation in the future, the new formation diagram obtained will definitely be much stronger than the new formation diagram integrated with the Zhoutian Xingdou Formation...

For a moment, Xu Feng began to hesitate, not knowing how to choose!

"If it were someone else, they might choose the first one. After all, a bird in the hand is worth a hundred in the forest. The most important thing is to improve their strength. But for me, the emperor-level powerhouse is within my reach. Within a hundred years, I will definitely become an emperor-level powerhouse. Then I can explore deeper into the void. There may be few Chaos Treasures in the upper realm, but they can still be obtained in the restricted area of ​​the void!"

Thinking of this, Xu Feng smiled slightly, chose the second option, and put the complete formation diagram back into the package column. This formation diagram might not be taken out for a long time in the future.

"What is this unknown emperor-level legacy? Why is it not in my parcel?" Xu Feng asked in confusion, but soon he recalled the scene of his spiritual consciousness surging just now;

The surging of his spiritual consciousness directly encompassed the entire upper planet. The feeling of controlling the entire planet like the Emperor of Heaven made Xu Feng unable to help but indulge in it. However, the surging of his spiritual consciousness was too terrifying, and even his body, which had an indestructible star body, could no longer bear it. The spirit and the body complement each other and are indispensable. When one of them improves too quickly, it will naturally affect the other, and the weaker one will become a burden. It was just like before, when Xu Feng suddenly gained the spiritual consciousness that only an emperor-level strongman could possess. Although the feeling of controlling everything was intoxicating, Xu Feng's body could not withstand the pressure caused by the surging spiritual consciousness. Otherwise, Xu Feng would not have vomited blood and been injured, and fainted again. If Xu Feng's spiritual consciousness really soared to the emperor level, his body would probably have collapsed at this moment, leaving only his spirit. At that time, Xu Feng could only seize another body or directly become a ghost cultivator and specialize in spiritual body cultivation. Thinking of this, Xu Feng could not help but look inward. After a moment, a surprised smile appeared on Xu Feng's face. “Yes, that unknown imperial legacy must be the spiritual consciousness of an emperor-level powerhouse. It’s a pity that my current body is simply unable to withstand the spiritual consciousness of an emperor-level powerhouse. Therefore, the surging spiritual consciousness has been automatically sealed. As long as my body grows to the emperor level, the spiritual consciousness will naturally be unsealed by then…” Xu Feng was secretly delighted.

Once Xu Feng really becomes an emperor-level powerhouse, he would feel excited whenever he thought about the degree to which his spiritual consciousness would transform his mind. "That's equivalent to the spiritual consciousness of two emperors. By then, I can completely crush any emperor-level powerhouse of the same realm with my spiritual consciousness. I can make him want to take action, but he won't even be able to raise his hands!" Xu Feng could not help laughing. After the harvest, the thick smoke and miasma in the forest had almost dissipated. At this time, there were no obstacles or traps on the way to the top of the mountain. Xu Feng could directly climb to the top to get the stone lamp that might be a chaos-level spiritual treasure.

Thinking of this, Xu Feng could not help but quicken his pace and rushed towards the top of the mountain;
