Xia Fei had a small bottle of liquid in his hand. The Cockscomb Stolen Scent juice was not poisonous in of itself, but it could make someone die an extremely miserable death.

The light purple liquid was translucent, and there were quite a few yellow impurities mixed in.

According to normal practice, Xia Fei, who was well versed in medicinal practices, would not only observe the viscosity and color of the liquid but would also test the liquid through scent and taste. However, this time, Xia Fei did not dare to do this. Such an insidious liquid could not be allowed to have the slightest contact with his body.

Fortunately, he had taken the appropriate defensive measures, and there had been no mishaps when extracting the liquid of the Cockscomb Stolen Scent.

"You have the liquid now, so you only have to spread the liquid over the incredibly poisonous Nine Night Plum; after which, you can just sit back and wait as Peacock Blue fuses with it. As Peacock Blue is attached to your arm, the success of the synthesis will, to a large degree, depend on your ability to control it," Oro sternly said.

Xia Fei nodded. Once the arrow was loose, there was no taking it back. Either Peacock Blue would fuse with Nine Night Plum and create a supreme mystical armament or the two would both be badly damaged, with Xia Fei even standing to lose Peacock Blue. With this heavy responsibility resting upon his shoulders, Xia Fei could not help but be a little nervous.

"Nine Night Plum has yet to take a host while your Peacock Blue has already been through many battles, two of the thirteen leaves having already grown out. It is much stronger than Nine Night Plum. Plus, Peacock Blue's trait is tenacity, never speaking of defeat and never giving up. As long as you and Peacock Blue fight until the end, your chance of success is extremely high," Oro encouraged him.

In truth, not even Oro was sure of success. After all, this sort of abnormal mystical armament synthesis was the stuff of legends. It was true that the ancestor of the Lionheart Race had succeeded in this feat, but it was not as if he had crawled out of his grave to instruct Oro in how to do it. Oro developed this method through assembling the various clues he could find in his clan's records, but he had no experience in implementing it.

Oro's confidence came from his acknowledgment of Xia Fei's performance. He felt that Xia Fei was far too abnormal and that there was something indescribable hidden in his bones.

"Begin! You can definitely do it!" Oro sternly said.

Xia Fei slowly poured the light purple liquid into the incubator liquid. Nine Night Plum lived in a plant incubator, and the liquid inside was responsible for providing all its required nutrients, which could be considered a highly advanced composite product. For this liquid equivalent to three bottles of mineral water to have sustained Nine Night Plum for one thousand years, it must hold an incredible amount of nutrients.

*Whoosh!*

The liquid rapidly turned, and Xia Fei could clearly see the light purple liquid slowly flowing through Nine Night Plum's veins. It was not long before this bizarre plant was tinged with a hint of the bizarre, light purple liquid running through its body like a little stream.

"It's time. Let out Peacock Blue. Remember what I said; success or failure will depend on Peacock Blue and whether or not you can coordinate with it!" Oro nervously said. This was the first Xia Fei had seen him in this state, nervous and excited at once, as if he had just taken his medicine.

*Whoosh~*

Immemorial Mystical Armament Peacock Blue moved out!

Two blue grassblades moved like hunting dogs, first inspecting Nine Night Plum from a distance. As mystical armaments, Peacock Blue shared a strange connection with Nine Night Plum.

Perhaps because Nine Night Plum's toxin was too strong, Peacock Blue slowly turned back after making its initial probe, waiting ten-some meters away from Nine Night Plum for the time to strike.

Temptation.

The Cockscomb Stolen Scent's powerful allure gradually began to work, and Peacock Blue grew more and more restless and irritated. The two grassblades trembled and shuddered as if they were dancing, wanting more and more to lunge at Nine Night Plum and absorb it.

Xia Fei saw Peacock Blue's excitement and knew that it was the moment to make his move!

"Go! That's a delicious feast over there! Consume it and you'll become a unique immemorial mystical armament. Among the Thirty Immemorial Mystical Armaments, you will be the strongest! There will be no other!"

With these words, Xia Fei urged Peacock Blue into bravely approaching the toxic Nine Night Plum. Nine flowers were like nine lanterns that led toward the path of the strongest. Peacock Blue trusted Xia Fei; its body coiled back like a snake before it lunged forward!

The immemorial mystical armament revealed its awesome power and began to fight with Nine Night Plum!

Shockingly, Nine Night Plum began to counterattack as if it were being controlled by someone!

Nine flowers bit down on Peacock Blue like the mouths of a monster!

The areas bitten rapidly yellowed and withered, losing their original vigor.

However, this death did not discourage Peacock Blue, and it began to regenerate the poisoned parts rapidly!

"Right! Just like that! Your Peacock Blue is the world's most tenacious grass. How could a small wound possibly subdue it? The battle has just begun, so don't give up until the very end!" Oro was even more agitated than the two combatants, constantly urging Xia Fei to land the killing blow.

Xia Fei naturally knew that he could not give up, nor did he have any plans to!

In the blink of an eye, Peacock Blue and Nine Night Plum exchanged three hundred blows! The battle between these two plant-type immemorial mystical armaments was intense beyond imagination, on par with a clash of apex experts!

Perhaps because it sensed that its life was in danger, Nine Night Plum put up a fiercer and fiercer resistance, like a cornered beast!

Peacock Blue fully exhibited its tenacity and stubbornness, the two blue grassblades attacking and defending in unison.

Xia Fei was so busy he had broken out in a sweat. Peacock Blue had the upper hand in large part because of his control. He tried to have it complete a set of highly difficult maneuvers equivalent to Sly Thrust. Even though Xia Fei had studied this complicated martial technique for a long time, making Peacock Blue move in the same way as he did was easier said than done.

However, as time passed, their coordination increased, and Xia Fei found it easier and easier to control his immemorial mystical armament, which came as a pleasant surprise to him. Peacock Blue was a weapon with a mind of its own, not like the Blood Crystal. If one wanted it to move left, it would move right, and if one wanted it to move right, it would move left.

Truly controlling the immemorial mystical armament's power required constant practice. Xia Fei had feared that other people might find out he had Peacock Blue, so he tried to minimize its use. After all, talented people and treasures would always be coveted by others, so it was best to take countermeasures.

Now, Xia Fei and Peacock Blue had the perfect chance to practice together. The longer and more difficult the battle was, the more Xia Fei and Peacock Blue synchronized.

This thought invigorated Xia Fei, and he controlled Peacock Blue and battled with Nine Night Plum for one day and one night! Battling to his heart's content, Xia Fei felt entirely satisfied!

"This isn't right. How could Nine Night Plum last this long? It's getting stronger and stronger. It's as if Nine Night Plum is also maturing in this battle alongside Peacock Blue!" Xia Fei frowned and said.

Oro nonchalantly said, "Nine Night Plum is still an Immemorial Mystical Armament, so it's only normal that it will mature. Besides, the stronger Nine Night Plum is, the stronger Peacock Blue will be once it subdues it. This is a good thing."

Xia Fei nodded, but he still felt inexplicably nervous. This was because Nine Night Plum had become extremely frenzied, brimming with a desire for blood!

Two more days and nights passed, and a large pile of empty crystals had gathered at Xia Fei's feet. The battle was so intense that he needed to recharge his energy constantly. In any case, he had plenty of crystals in the bank, so Xia Fei decided to go all-out! This was the advantage of having money. One could eat whatever and however much they wanted!

Amid the battle, there was suddenly a new development!

Nine Night Plum began to grow crazily from two-some meters tall to one hundred meters! It was on the verge of reaching the top of the alloy dome!

Xia Fei's brows furrowed and swiftly jumped away while staring at the frenzied Nine Night Plum.

"What's going on?!"

"Oh, no! I was so focused on Peacock Blue's battle with Nine Night Plum that I forgot to tell you about the Cockscomb Stolen Scent's seventy-two-hour mutation," Oro said with some remorse.

"What mutation? What seventy-two hours?"

The Cockscomb Stolen Scent's liquid can not only trigger one's desires but can also harness the potential energy in the victim's body. Seventy-two hours have now passed, so Nine Night Plum will unleash all of its potential and will fight until not a shred of life remains in it!"

Xia Fei was stunned. Nine Night Plum was an Immemorial Mystical Armament! It was impossible to say how much potential energy it contained or how much more powerful this savage Nine Night Plum was now! Too terrifying! Too bloodthirsty! Peacock Blue's grassblades were being torn apart!

If this continued, Nine Night Plum would ultimately die after unleashing all of its potential, an enormous loss. Xia Fei could not just stand back and watch as his plan to fuse the immemorial mystical armaments failed and Nine Night Plum turned to ash.

"There isn't much time left! I'm going all-in!"

Xia Fei roared, and Peacock Blue suddenly grew to a length of five hundred meters.

The giant blades of grass became like steel, sweeping, hacking, cutting, and thrusting. Each move contained incredible force. After three days and nights of constant wearing away, Xia Fei had developed some basic understanding with this Immemorial Mystical Armament! Its power was simply immense!

Alas, the potential energy of Nine Night Plum was also incredible, and Xia Fei and Peacock Blue were unable to do anything to this most poisonous plant!

Its body was still growing, already at one hundred fifty meters! The alloy dome began to groan. This was a four-layer defense, the most advanced defense the robots could develop! This was how powerful Nine Night Plum was!

The seconds continued to pass, and Xia Fei no longer had time to delay. Nine Night Plum was on the verge of withering away. To him, waste was a crime, let alone wasting an immemorial mystical armament!

Suddenly, Xia Fei had a terrifying idea!

If there was anything that could flip around the universe, it was the Law of Primal Chaos! That unreasonable energy that could reverse black and white!

"Take this!" Xia Fei bellowed. He would rather risk the unknowns of the Law of Primal Chaos than waste this precious Immemorial Mystical Armament!

Whether it was a blessing or a curse, he would have to take the gamble first, and Xia Fei was willing to take this gamble!

"No!" Oro exclaimed. "The last time you used this strange law, you created the heaven-defying Blood Crystal. There's no telling what will happen if you use it on two Immemorial Mystical Armaments! At worst, you can just give up! You will still have Peacock Blue at least!"

"I don't like giving up!" Xia Fei's response was simple and it echoed out loud.
