The Heavenly Deficient Demonic Dragon of Fire and Ice's main ability was to devour time.
However, it couldn't be used against opponents who were too weak.
The demonic ancestor's explanation was that the power of time devoured from weak opponents would be less effective when used on Kang Shin-mu. In other words, two hours of time devoured from an opponent would be equivalent to less than one breath for Kang Shin-mu.
That was why it wasn't necessary.
However, if he was on par with Kang Shin-mu, the more time Kang Shin-mu devoured, the more time Kang Shin-mu could use.
That was more or less what it meant. In any case, it was very difficult to cultivate by devouring the time of the weak.
He had to find an opponent who was on par with him or someone stronger than Kang Shin-mu.
Moreover, this method wasn't suitable to be used in public. It was more suitable to be used in secret, such as in the Supreme Ruins … That was why Kang Shin-mu could put the Heavenly Deficient Demonic Dragon of Fire and Ice's abilities aside for the time being.
He would first increase his combat ability in other areas!
Speaking of which, Kang Shin-mu hadn't fought in a long time.
He had yet to use the Illusory Ghost Book and the Great Compassion Heavenly Dragon Seal, but he would familiarize himself with the two Heaven Grade Saint Spiritual Dragon Weapons when he had the time. Now, he could already unleash sixty percent of their power.
The more intense the battle, the more compatible the dragon warrior and the dragon weapon would be. If they could achieve one hundred percent compatibility, they would be able to fuse and unleash greater power.
It was already impressive that Kang Shin-mu could use sixty percent of the sky-grade Holy Dragon Weapons' power. After all, it hadn't been long since he'd obtained the two weapons.
The day before the arena battles.
Kang Shin-mu and the others were still cultivating at Emperor Xi's Dragon Martial Academy office in the Martial Dragon Fortress. Kang Shin-mu was constantly improving his Ninth Extreme Dao Hui Dragon Explosion. He was now at the peak of the Sixth Extreme Dao Hui Dragon Explosion, but he was still far from the Seventh Extreme Dao Hui Dragon Explosion.
Even though Kang Shin-mu had been cultivating this high-grade Holy Spirit Dragon martial technique recently, it was still very difficult for him to cultivate it to the high level of the Seventh Stage Explosion.
After all, it was considered a high-level mastery. Once it was mastered, there would be a qualitative change. It was normal for Kang Shin-mu to fail to achieve it.
And at this moment, Kang Shin-mu felt an incomparably tyrannical aura descend upon him.
It appeared near the office of Emperor Xi's Dragon Martial Arts Academy!
"This is … the aura of a supreme divine dragon!"
"Two from the Martial Dragon Fortress!"
Jiang Shenwu's expression changed slightly. There were only two Supreme Dragon Martialists who would come to the Martial Dragon Fortress at this time. It could only be those two.
The Divine Dragon of Emperor Xi, and the Dragon of Azure Sky Calamity!
Kang Shin-mu had heard of these two supreme Divine Dragons too many times, but he had only seen them a few times.
At this moment, Linghu Die 'er ran over and knocked on Kang Shin-mu's door. "Kang Shin-mu, the Divine Dragon of Emperor Xi is here. Why aren't you coming out to greet him?
You should take this opportunity to formally acknowledge him as your master! "
Linghu Die 'er also knew that Kang Shin-mu had been taken in as a personal disciple by the Divine Dragon of Emperor Xi.
Hence, she directly ran over to inform Kang Shin-mu.
In an instant, the entire office of Emperor Xi's Dragon Martial Arts Academy became tense. Countless dragon martialists, including Instructor Dragon Emperor, all woke up from their closed-door training and rushed to the central hall of the office.
Kang Shin-mu was no exception.
He walked out of the courtyard and saw Linghu Die 'er. Along the way, he called Liang Xiao, Xiao Bai, Xiao Yuhua, and Ran Ran over and walked to the hall.
Linghu Die 'er led the way in front. Soon, they followed a large group of people to the hall of the office of Emperor Xi's Dragon Martial Arts Academy.
This was the most crowded place in history. On one hand, all the dragon martialists were preparing for the arena battles. On the other hand, the arrival of the Divine Dragon of Emperor Xi was also a great attraction to the students of Emperor Xi's Dragon Martial Arts Academy.
Kang Shin-mu followed Linghu Die 'er to the hall and saw a figure that he had met once before.
It was a woman with long black hair. She exuded a majestic aura, but in reality, her aura was not revealed. It was only the aura of a strong cultivator that was naturally displayed. It made people feel awe and respect.
The woman with long black hair was dressed in a red robe. Her eyes seemed to be filled with flames, and her every move seemed to have the power to destroy the world.
This was the Divine Dragon of Emperor Xi!
Of course, this was the human form of the Divine Dragon of Emperor Xi. She appeared in the office of Emperor Xi's Dragon Martial Arts Academy, and this time, she did not put on any airs.
The last time Kang Shin-mu saw the Divine Dragon of Emperor Xi was when the crack in the void had just appeared. After killing the demonic creatures in the void in the starry sky to train, the Divine Dragon of Emperor Xi back then was extremely majestic.
Of course, that was in front of all the students of the four great dragon martial arts academies.
This time, it was different. She was only facing her own students from Emperor Xi's Dragon Martial Arts Academy. They were all on the same side, so there was no need for her to maintain absolute majesty. It was also necessary to be a little more relaxed so that the students would fear her less and respect her more.
"Kang Shin-mu, you are here," the Divine Dragon of Emperor Xi spoke.
Her voice was very pleasant to the ears, and it did not have the same majestic feeling as last time.
If one had to compare it, it would be like a parent talking to their child.
"It is me, Senior Emperor Xi."
Kang Shin-mu immediately nodded respectfully.
He saw that beside the Divine Dragon of Emperor Xi, Yu Yaji, who was also dressed in red, was standing. Yu Yaji was smiling at him.
Yu Yaji was one of the personal disciples of the Divine Dragon of Emperor Xi.
Kang Shin-mu was also about to become the personal disciple of the Divine Dragon of Emperor Xi. In other words … he would have to call Headmaster Yu Yaji "Senior Sister" in the future?
In that case, he would be in the same generation as Yu Yaji.
This made Kang Shin-mu think of a person. Yu Tianchang, the genius dragon martial artist with the image of a big sister, was actually a generation younger than Kang Shin-mu. This made Kang Shin-mu feel that the world was unpredictable.
"The rest of you, disperse first.
Kang Shin-mu, come with me. "
The Divine Dragon of Emperor Xi nodded slightly at Kang Shin-mu. Then, with a faint smile on her face, she turned and walked into the depths of the office.
In an instant, the other unrelated people naturally dispersed and looked at Kang Shin-mu with envy.
Both the male and female students were very envious of Kang Shin-mu. They had all heard that Kang Shin-mu was already the personal disciple of the Divine Dragon of Emperor Xi. It was just that he had not formally acknowledged her as his master yet.
Now, it should be time for him to formally acknowledge her as his master, right?
Kang Shin-mu also thought so. At this time, only he and Yu Yaji were still following the Divine Dragon of Emperor Xi. Even Linghu Die 'er had taken the initiative to block the others behind her.
Very quickly, the three of them came to a courtyard deep in the office. This courtyard was the residence of Yu Yaji, the Headmaster. It was already the least likely place for outsiders to disturb the office.
