The unlocking of the Killing Sword Master did not make any big noise, but Lin Huang vaguely felt that the unlocking of Black Tan this time would be quite a small move.

Dragon's Blood Grass, he had already arrived after the last auction, and within a few days, he asked Yang Ling to help unlock the Emperor's Heart Ring and take out the Dragon's Blood Grass. He has not unlocked the black charcoal for a long time, also in order to wait for himself to have time to come to this independent space.

Because the smell of black charcoal is so noticeable, it hasn't been released for a long time.

When he was summoned this time, he immediately looked at Lin Huang pitifully, looking like he had been wronged.

"Okay, when you complete the unlocking this time and enter the adult state, you can cover your breath. In the future, if you need to fight, you will be called. Lin Huang reached out and touched the black charcoal head, and said comfortingly.

Hei Tan immediately brought his head to Lin Huang, stretched out his tongue and licked his saliva.

"Okay, okay, don't make trouble, it's important to get down to business, let's unlock it quickly!" Lin Huang took a tissue and wiped his face clean, he really couldn't stand the way of expressing friendship with black charcoal.

"Brother, this is...... Dragon?" Lin Xin's voice came a little weakly.

Only then did Black Tan notice that in addition to the thunder he was familiar with, there was actually a human girl next to him, and he immediately looked at Lin Xin with some curiosity.

Lin Xin also looked at it curiously.

A man and a dragon just stared at each other with such big eyes.

"This is my summoned beast, and it's called Black Carbon. Lin Huang introduced, and then turned his head to look at Hei Tan, "Hei Tan, this is my sister, Lin Xin." ”

Hearing Lin Huang's introduction, Hei Tan let down his vigilance.

"Can I touch it?" Lin Xin asked Lin Huang with an expectant face.

"Yes, it doesn't bite. Lin Huang nodded, and did not say the remaining half of the sentence "It only eats people".

"Come, black charcoal, don't bite. Lin Huang guided Black Tan to lower his head and slowly came to Lin Xin, and then put Lin Xin's hand on Black Tan's head.

Lin Xin reached out and touched it, with a little roughness in the cold, and Hei Tan's eyes narrowed slightly, as if he was enjoying this touch.

Lin Xin's face was excited and surprised, she didn't expect that she would be able to come into contact with this legendary creature. Although Lin Huang didn't say that it was just not a real dragon blood species, even if it was just a wurm, it was enough to surprise people.

After letting Lin Xin touch it for a while, Hei Tan pulled his head away and looked at Lin Huang again.

Lin Huang took out twelve dragon's blood plants from the storage space.

Each plant is about the size of an adult's palm, and its whole body is blood-colored, and even a little crystal clear in the sunlight. It's not like a plant, it's more like a hand-carved handicraft.

Black Charcoal's face was full of excitement after seeing it, and when Lin Huang was thinking about how to use these dragon's blood grasses, he stretched out his tongue and rolled all the twelve dragon's blood grasses into his mouth, and then began to chew.

"Xiao Hei, is it okay to eat it directly?" Lin Huang immediately asked, he knew that if Wulong wanted to promote the dragon blood species, he needed to eat the dragon blood grass, but it would only be effective if he ate a large amount of it.

[Under normal circumstances, Dragon's Blood is fused as a material with Dragon's Blood cards.] However, it is okay for him to eat it directly, and it can also activate the fusion effect of the system. 】

"Then why do other dragon's blood species or wurms have to eat a large amount of dragon's blood grass to be effective?' is it because the extraction efficiency of dragon's blood grass is different?" Lin Huang raised this question again.

[The extraction efficiency only accounts for a small part of the reason, taking it directly will indeed waste the blood factor contained in the dragon's blood grass, probably only 20% to 30%, and the system extraction effect can reach 100%, but this is not the main reason. 】

[The blood factor of dragon's blood grass does not directly increase the concentration of dragon's blood, but plays an activation effect. This is also why, some of the same wurm can be promoted by eating a small amount of dragon's blood grass, while some people can't be promoted by eating a large amount of dragon's blood grass. This is related to the individual's physique, and some are more sensitive to the stimulation brought by dragon's blood grass, so only a small amount of dragon's blood grass is needed to activate the dragon's blood activity in the body and deepen the concentration of blood factors. Some are not sensitive to the stimulation of dragon's blood, so it is difficult to activate dragon's blood activity by eating a large amount of dragon's blood. All the system does is increase the activation to 100%. 】

"Understood!" Lin Huang finally understood the effect of the dragon's blood grass.

After chewing the black charcoal on the side a few times, it found that although the dragon's blood grass smelled okay, it didn't taste very good, but it also knew that it was related to its own unlocking, so it had to swallow it forcefully.

A moment later, another white light shone down from the sky, enveloping the black charcoal in its entirety.

Lin Huang took Lin Xin and Thunder back a few more steps, stepped aside, and patiently waited for the unlocking of the black charcoal to be completed.

After being shrouded in white mangs, a trace of black flame began to automatically escape from Black Charcoal's body, as if it had penetrated from the pores of his body, and soon enveloped Black Charcoal's entire body, and Black Charcoal's body began to burn automatically.

Seeing this scene, Lin Huang couldn't help but feel a tightening in his heart.

Seeing this, Lin Xin hurriedly asked Lin Huang, "It's going to be fine, right?"

[Rest assured, this is normal]

Lin Huang was a little hesitant, and Xiao Hei's voice suddenly came from his ears, and he was relieved.

"It's going to be fine. He also shook his head at Lin Xin and said.

After being enveloped in flames, the aura of the black charcoal swelled slowly, but its size seemed to be growing rapidly at a speed visible to the naked eye.

At first, it was only five or six meters long, but it was only a short time, and it had grown to more than ten meters.

Lin Huang pulled Lin Xin and Thunder back a few more steps.

As the minutes passed, the size of the black charcoal grew larger and larger, and after almost three hours, the length of the black charcoal had skyrocketed to a thousand meters, like a mountain lying in the air.

Although it was completely wrapped in black flames and couldn't see clearly, the original little cutie should have turned into a hideous beast now.

After reaching this size, it seems that its body shape has finally been fixed, and there are no more changes. However, the aura began to show.

Previously, with the skyrocketing in size, Lin Huang felt that its aura had indeed broken through the limit of the Golden Realm's consummation and arrived at the White Flame Realm, and he didn't feel how strong it was. But as this body shape was fixed, his aura began to undergo a drastic metamorphosis.

At that moment, Lin Huang felt the feeling he had from the Lord of the Absurdity and from Bai before, the undoubted ......

On the black charcoal's body, the terrifying coercion erupted violently, and Lin Huang hurriedly propped up the dark barrier to isolate the influence of this coercion on Lin Xin.

This kind of terrifying coercion was fatal to Lin Xin. Even if it is a strong person in the Golden Realm, under this coercion, he will not be able to resist at all, and can only be slaughtered by others. Of course, Lin Huang and a few other demonic powerhouses may be exceptions.

The coercion lasted only a few seconds before it quickly dissipated, and the white light above the sky finally began to dissipate. The black flames around Black Charcoal also began to slowly converge, revealing their true appearance after unlocking.

"Why do little cuties become ugly when they grow up?" Seeing the current appearance of black charcoal, Lin Huang couldn't help but give this emotion in his heart.

The appearance of Black Charcoal completely turned into a black giant dragon beast, which looked extremely powerful in combat, but it was also extremely hideous.

[Congratulations to the host, complete the unlocking of the epic monster card Undead Baby Dragon (Black Charcoal).] Your epic monster card, the Undead Young Dragon (Black Charcoal), has been unlocked and is automatically promoted to the White Flame Realm. 】

[Congratulations to the host, the bloodline of the undead young dragon (black charcoal) has been improved, and it has been promoted from a beginner dragon blood species to an intermediate dragon blood species!]

[Congratulations to the host, the undead young dragon (Black Charcoal) has been advanced, from an epic card to a legendary card!]

[Congratulations to the host for obtaining the legendary monster card - Undead Evil Dragon (Intermediate Dragon Blood)!]

Without waiting for Lin Huang to check the information of the black carbon, a prompt sound suddenly came from Xiao Hei's side.

[Due to the lack of host permissions, the legendary monster card cannot be used, and the monster card undead evil dragon is automatically sealed.] When the host is promoted to the Holy Fire Realm and the authority is raised, the card will be automatically unsealed. 】

"Can't you make me happy for a while?!" Lin Huang was speechless.
