The strongest dragon in the age of beasts.

Chapter 339 Black Dragon Mutation
Hearing this, Chen Wei's face softened.

Although it is still difficult for Cai Ling and Yu Tong to unleash a peak sixth-level king's attack, it is not impossible. It is much easier than he expected before!

Chen Wei's eyes flickered, and he asked loudly: "If we can break through your source power furnace, senior, does it mean that we have successfully passed the level and can ascend to the Sky City?"

The Xuanjia Black Dragon raised its head proudly, "Of course not. Breaking my source power furnace will only make me lose the blessing of infinite energy. Only by completely destroying my head can I be considered a successful breakthrough."

"Another thing to remind you, your time is running out. If you can't defeat me within twelve days, your team members will definitely not survive!"

After finishing speaking, the huge alloy wings on the back of the mysterious black dragon spread out instantly, and then the whole dragon rushed to the high altitude of the training room.

Chen Wei took a deep look at the back of Xuanjia Heilong, then retracted his gaze, looked down at Cailing and Yutong, gritted his teeth and said with a ruthless expression.

"Everyone work hard, the next is the critical moment for us to quickly improve our strength. As long as everyone works hard, I will be able to take care of all the strengthening of the power of Yulong during this period!"

Hearing this, Cai Ling and Yu Tong's eyes lit up immediately.

……

Time flies, and in a blink of an eye, nine days have passed.

During these nine days, Chen Wei and the two pets have been staying in the training room for strengthening and training, living a life of penance without going out of the door, and occasionally accepting the guidance of the black dragon.

With the help of Xuanjia Heilong, Yutong mastered the whole body of Shenglongtang on the fifth day of training, and even the racial skills Purgatory Aurora and Burning Dragon Crown that he had not comprehended for a long time were fully introduced, and his strength level was completely stable. At the bottom of the fourth rank.

But Cailing's learning speed of Shenglongtang was relatively slow, and it was not until the eighth day of training that he fully mastered Shenglongtang.

On the contrary, after the advanced level, the Eternal Frost Sealing and Slow Space training progressed very quickly, and the mastery of the skills was directly raised from the entry level to the proficient level. Even her strength was at the bottom of the fourth level due to the increase in skill proficiency. A big step.

But compared to these, what surprised Chen Wei the most was that Cai Ling's Frostfall Ember skill had reached the perfect level.

The perfect level of Frostfall Embers can not only double the power of Cai Ling's ice-type skills, but also has an additional feature [Jin Dye].

That is, the source power and life force deprived by the embers of frost falling on the opponent can be bless the ice-type skills released by Cailing as much as possible, so that the power of Cailing's already terrifying ice-type skills becomes even more outrageous.

"Are you ready?"

Looking at the two pets in front of him whose strength has skyrocketed, Chen Wei showed a satisfied smile on his face.

During this period of time, in order to avoid the exposure of the power of Yulong, he used all his physical strength every day to strengthen the two pets. He didn't even strengthen a high-level dragon crystal. The reason for the skyrocketing strength in a short period of time.

"Yeah." (**) (It's totally fine.)
"Mi!" (o▽)o (Me too.)
Cai Ling and Yu Tong glanced at each other, with eager expressions on their faces.

Of course, the eighth-rank legendary emperors in their heyday cannot beat them, but the legendary emperors of the third-rank upper rank are another story.

With the same strength, or even a superior level of strength, they don't think they will lose to other beasts.

"Very well, then let's go, senior is still waiting for us on the cliff of partition."

Chen Wei opened the door of the training room, looking at the beam of light that almost connected to the sky city in the distance, with a cautious expression.

"Success or failure is here!"

At this time, the members of King Qin's team who were detained by the black dragon in a separate prison and watched Chen Wei leave alone suddenly had question marks all over their heads.

"Could it be that this guy is planning to single-handedly challenge the Xuanjia Black Dragon?"

……

The core area of ​​the remains of the first emperor, the cliff of separation.

Walking on the steel bridge made of source steel links, looking up at the beam of light shining with blue light above, Chen Wei was a little lost for a while.

You must know that in the eyes of most beast masters, legendary powerhouses are transcendent existences that are elusive and unattainable, but now I have to face a legendary one with the beast, this is really an exciting feat .

Thinking of this, Chen Wei couldn't help clenching his fists.

"Calm down, you are going to become a legendary powerhouse in the future, you are not just a black dragon, just overthrow it today."

Just as Chen Wei was suppressing his inner excitement, there was a muffled thunderous noise in the sky.

"Boom!"

As if to play cool, the jet-black lightning turned into countless black thunder pillars and bombarded the ground, and the ground was scattered with rocks, and the deafening and terrifying sonic boom rang in Chen Wei's ears.

Afterwards, a dark armored black dragon with a size that covered the sky and the sun let out a thunderous roar under Chen Wei's nervous eyes.

"Why are you alone?" Looking at Chen Wei who was alone in front of him, the Xuanjia Heilong was slightly taken aback.

What's going on, little brother, you want to fight against the legend alone, are you inflated!
Without the help of the Beast Familiar's cooperation, trying to break through its defense with the combined strength of two Tier [-] pet beasts would be too contemptuous of its gold content as a legendary race.

Don't you know that Chen Wei was also taken aback, and said softly, "Can't you do it alone?"

Hearing this, Xuanjia Heilong blinked his majestic eyes.

What's going on, are young people these days so crazy?
"Without the giant spirit power of the beast master's cooperation, how are you going to break through my legendary realm? Why did you bring those beast masters in?"

Xuanjia Heilong was a little confused, he left the prison key to Chen Wei just to let him subdue the team that was not bad.

Even if Chen Wei couldn't subdue that team in the end, it would be enough to get them to help complete the Beast Familiar collaboration!
And now it's all screwed up! ! !
"What is the Legendary Domain?" Chen Wei asked with a thought.

Needless to say, he really doesn't understand something that sounds so high in the Legendary Domain, and there is no way to understand it.

Xuanjia Heilong widened his eyes in surprise: "???"

What's going on, you kid, as a genius of the Beast Familiar family, you don't even know this bit of information!

……

"I see."

Soon, after listening to Xuanjia Black Dragon's narration, Chen Wei suddenly had a new understanding of the horror of the legendary powerhouse.

"Since this is the case, I can only use the power of King Qin's team to perform the Beast Familiar Cooperation. I don't know if they agree or not?"

After pondering for a while, Chen Wei planned to turn around and go back to discuss with King Qin's team, anyway, there was still time.

However, at this moment, Xuanjia Heilong's body froze suddenly, a crimson light flashed in his eyes, and the intelligence in his eyes completely disappeared.

The huge body stopped in front of Chen Wei in an instant, and a terrifying momentum erupted.

"Crossover, the assessment has officially begun!" A mechanical, emotionless voice suddenly sounded.
