"I also want to level up quickly, so that I can protect Yaoyao in the future, instead of letting Yaoyao protect me."

"It's best that you can have such thoughts. After such a battle, I have also found that we need to be vigilant all the time. Otherwise, I'm afraid that there will be a situation similar to Feng Yao. ”

"Hmm. There is also Bai Ze blood, which we also need to find. However, something suddenly occurred to me. What is that green orb that exploded after killing Knoros before? ”

Oxygen Lemon said, pulling out the loot from his backpack.

The green magic ball emitted a faint glow of fluorescent green in the hand of the oxygen lemon, and it was so hazy that even Nie Fan couldn't tell what it was.

There's not even a system prompt that's supposed to be.

"I don't even know what the game system is, it seems that this guy Knoros does keep some treasures."

"Maybe in the future, if you have the chance, you can always discover the mystery of this thing."

Oxygen Lemon said, put away the green magic ball, looked back at Feng Yao lying on the bed, and left.

In Heavenly Fantasy City, there is no one who can do anything in the city, so Feng Yao's safety can be completely guaranteed. It is precisely for this reason that Oxygen Lemon can rest assured that Feng Yao can stay here.

After instructing the innkeeper to take good care of Feng Yao, Oxygen Lemon handed her 500 gold coins and left.

The innkeeper who was happy to mention 500 gold coins couldn't be happier, patting his chest and assuring that Feng Yao would never be hurt at all.

When the Oxygen Lemon reappeared, it was the entrance from the third floor of the Yin Soul Hall to the fourth floor. The Shadow Knights obediently waited here, waiting for the return of the Oxygen Lemon.

Seeing Oxygen Lemon and Nie Fan, the Yin Soul Knight hurriedly ran over: "Master, how is Feng Yao?" ”

"It's okay, just rest for a while. Now, I need to work on unfinished business. ”

"Yes, master."

After saying that, the Shadow Knight obediently crouched in front of the oxygen lemon. Under Nie Fan's instructions, Oxygen Lemon took out the best quality finger bone and activated the [Hand of God] skill.

A flash of golden light surrounded the phalange, and after a while, the phalanx completely turned silver, a few points more beautiful than the original color.

"If this phalanx bone can be successfully adapted, the strength of the Yin Ghost Knight will be much stronger than before, and his ability to regulate the body will be a little more like that of a human. However, if the adaptation is not successful, not only will this phalanx bone be costly, but the strength of the ghost knight will also be greatly reduced, so we need to be mentally prepared. ”

Before starting the [Yin Soul Assembly Technique], Nie Fan needed to talk about these consequences. If the adaptation is not successful, they will lose a big general, and the cost to them is immeasurable.

"It's okay, master, come on, I can do it!"

The Shadow Knight closed his eyes, ready to die. From the beginning of knowing Feng Yao, there was suddenly a different thing in its consciousness, that is, guarding Feng Yao.

Because Feng Yao was the first one he knew, he could treat his friends equally.

"Okay, I'll use a few other phalanges to match you, and the success rate can go up a bit." Without Feng Yao's aura, no one dared to guarantee that all the next adventures would not fail, so Nie Fan had to do his best to ensure the success of this matter.

"Tear down the Shadow Knight, and press those five phalanges on our left hand side into this position."

"No, it's wrong. The bone is offset to the right by another two millimeters. ”

"There's also this one, there are already signs of cracking in the bones, let's change to another bone, just that one, right."

Under Nie Fan's command, the hands of the Oxygen Lemon Assembling Yin Soul trembled slightly. Who would have thought that such a tsundere little girl would play with blocks under the guidance of a sword?

In order to keep improving, she didn't dare to be a little lazy, even if the sweat on her forehead dripped on her arms, she didn't mind.

A few ghost soldiers beside him slowly walked to the side of Oxygen Lemon, and somewhere they got some shabby clothes to fan Oxygen Lemon. In this way, her mind can be more stable.

With the assistance of everyone, the prototype of the Shadow Knight has been roughly completed. The only thing missing is the core phalange.

"Is that what you want to do?" Oxygen Lemon was holding this [Bright] level phalange, and there was some tension. If it fails, then these few hours will be in vain.

"Well, when you put it in, lift me up and aim the tip of your sword at it, understand?"

"Okay."

Following Nie Fan's command, Oxygen Lemon carefully sent this finger bone up and placed it in the heart of the Shadow Knight.

As soon as this [Bright] level phalanx touched the other parts, it was immediately absorbed, and the sound of electricity could be heard in it, presumably communicating with other body parts.

After the placement was successful, Oxygen Lemon raised Nie Fan, and the tip of the sword was aimed at the core phalanx of the Yin Knight.

"Lemon, you're going to have to take it. No matter what happens, don't let go, and don't stray from the direction, you know? ”

"Well, okay, I'm ready, let's get started!" Oxygen Lemon wiped the sweat from her head, very firm.

"[Yin Soul Assembly Technique], activate!"

I only heard a sound of "bang", and a blue light shot out from the tip of Nie Fan's sword, first shining on the position of the core phalanges, and then slowly spreading all over the body.

"[Domination Progress]: 10%."

"[Domination Progress]: 20%."

"[Domination Progress]: 30%."

Watching the dominating progress bar move forward little by little, Nie Fan breathed a sigh of relief. Now it seems that everything is going well.

"[Domination Progress]: 40%."

"[Domination Progress]: 50%."

When the domination progress reached fifty percent, a black qi emerged from the Yin Ghost Knight's body out of thin air, and the domination progress also stopped at fifty percent, no longer growing.

Looking at this black gas, Nie Fan couldn't help frowning. In this way, it seems that there is still a backlash, and the progress is not so smooth.

I saw that the black gas was slowly condensing in the air, and I couldn't see any shape for a while. Oxygen Lemon naturally discovered this scene and hurriedly asked Nie Fan: "Nie Fan, what is that?" How did such a thing come out of the ghost knight's body? ”

"I don't know, but it must be hard to mess with. Pull yourself together, there could be a fight next, and it will be even tougher than the one against Knoros. ”

The reason why Nie Fan said this was because when he saw this black qi, his soul trembled slightly.

It was an anomaly he had never seen before.
