Bone Fusion! Laying the Foundation for the Future!

After indulging in some daydreaming in his mind, Xu Xingyu decided to find a quiet place to fuse the Dragon King's Soul Bone and the God-given Soul Ring. He then asked Ajinxing if there was a secret room inside the Dragon Tower where he could fuse them in peace.

After all, both fusing Soul Bone and fusing Soul Ring are processes that cannot be disturbed by others; otherwise, if a mistake is made, the Soul Master's life may be in danger.

A Jin smiled and said, "If you want to fuse Soul Bone, you can do it right here. This is the central space of the Star Dragon Tower, and no one but you and me can force our way in. It also gathers a lot of energy here, which will be helpful when you fuse Soul Bone and Soul Ring. As for me, I can protect you if you don't mind."

Upon hearing Xu Xingyu thought for a moment and then replied, "Then I'll leave it to you."

After saying that, he immediately sat cross-legged on the ground to prepare for the upcoming fusion.

It should be noted beforehand that this does not mean Xu Xingyu completely trusts A Jin. After all, he knows nothing about A Jin except that he is the successor of the Time Dragon King. Therefore, he still retains some wariness towards him.

However, one thing he was certain of was that neither his father, the Dragon God, nor the first Time Dragon King would randomly choose anyone to be the Dragon God High Priest and his successor.

Xu Xingyu might not be able to completely trust the other party, but he could choose her Dragon God and Time Dragon King. Besides, he could vaguely sense that the other party genuinely wanted to help him, so why not give her a little trust?

Stopping thinking about these trivial matters, Xu Xingyu first took out the torso bone of the Mountain Dragon King. He planned to fuse with the Mountain Dragon King's torso bone first, not only because it could greatly improve his defense and control over earth elements, but also because it could enhance his Bloodline Power.

If the Golden and Silver Dragon King each inherited half of the Dragon God's power, then the Nine Great Dragon Kings were created by the Dragon God with a portion of his authority at the time of creation.

The powers of the seven Dragon King —Light, Darkness, Wind, Earth, Fire, Water, and Space—all belong to the creative power of the Dragon God, which is the authority inherited by the Silver Dragon King.

The remaining Mountain Dragon King and Time Dragon King were granted the authority of stability and time, which is contained within the destructive authority inherited by the Golden Dragon King.

This is why, although the Light Dragon King has the highest cultivation level among the Nine Great Dragon Kings (excluding the first Mountain Dragon King), in terms of raw strength, the Mountain Dragon King (the successor after the first generation) and the Time Dragon King (theoretically the weakest in cultivation) can stand shoulder to shoulder with the Light Dragon King.

The Mountain Dragon King's stable authority is essentially an interference with the concepts of gravity and defense; the control of the earth element is merely secondary. The Time Dragon King's authority over time is not simply about predicting the future or reversing and traveling through time, but rather about editing time to a certain extent.

Since both powers are based on the power of destruction, the Mountain Dragon King and the Time Dragon King, as users, possess physiques that surpass those of normal Dragon Clan.

This is why Xu Xingyu chose to fuse with the Mountain Dragon King's torso bones. This way, his enhanced physical body would not only be able to more easily absorb the Light Dragon King's Soul Bone and God-Given Soul Ring, but the Bloodline Power provided by the Mountain Dragon King Torso Bone could also lay the foundation for him to condense Blood Essence Soul Ring in the future.

Xu Xingyu's current Soul Power Level is at the peak of Level 89 Soul Douluo. To break through this peak and reach the level of Level 90 Titled Douluo, Xu Xingyu must further compress and condense his Soul Power into a Soul Core at this time.

The problem is that Xu Xingyu already has a Mental Attribute Soul Core, which means that if he wants to break through to the level of Titled Douluo, he must condense Second Soul Core. The difficulty of condensing Second Soul Core is far greater than that of condensing First Soul Core, because the process of condensing and containing the Second Soul Core will be interfered with by the First Soul Core.

If one wants to survive this process, the only way is to use methods such Isotopic Resonance or Yin-Yang Complementarity to condense the Soul Core.

The essence of the method of Isotopic Resonance is to first identify the action pattern and frequency of the First Soul Core, then make the Second Soul Core imitate the action pattern and frequency of the First Soul Core, and then when the patterns and frequencies of the two are close, make the Second Soul Core accelerate suddenly, turning one center into two centers.

The principle of Yin-Yang Complementarity allows the power of two Soul Core to merge through collision, enabling the Soul Master's power to recombine, be purified, and condense, thus achieving the sublimation of Soul Power and compatibility with the characteristics of two different powers.

Of the two methods, the Yin-Yang Complementarity method is the best in terms of both Soul Power recovery and improvement of Soul Power quality. However, it is also the most difficult method to implement for condensing the Soul Core. Currently, only the Beast God Di Tian has succeeded in this method on the continent.

Xu Xingyu sister, Xu Yanxue, also known as the former Snow Empress, once tried to use the Yin-Yang Complementarity method to condense Second Soul Core in order to officially advance herself to the level of Limit Douluo Soul Beast in order to cope with the upcoming Heavenly Tribulation. However, she ultimately failed because her physical and mental strength were insufficient.

Therefore, if one does not have sufficient physical and Spiritual Power to implement the Yin-Yang Complementarity method, it will definitely fail. However, Xu Xingyu's current strength, both in terms of spirit and body, far exceeds the standard, after all, they are at the God Level.

However, the power of the two is not very balanced. Since Xu Xingyu's Spiritual Power level is one level higher than that of her physical body when she condenses her Spiritual Soul Core, this is why Xu Xingyu chooses to prioritize improving her physical strength.

This way, the chances of making mistakes when Yin-Yang Complementarity will be greatly reduced. Furthermore, the Second Soul Core he is preparing to condense is Bloodline Soul Core, so it is necessary to lay the foundation for a more powerful physique.

The Mountain Dragon King Torso Bone in his hand transformed into a yellow light and merged into Xu Xingyu's body. In that instant, he felt as if he had become a great mountain, with the majestic peaks connecting with the earth. Countless energies surged from all directions and merged into his body.

As the earthy-yellow energy washed over him, Xu Xingyu could clearly feel his torso bones, including his spine, sternum, and ribs, all covered in a dazzling luster. It was as if he had donned a suit of diamond armor for his torso. The indescribable solidity filled him with power.

Countless Bloodline Power began to fill Xu Xingyu's body, and her body, which was originally only at the level of Third-Level God, began to show an upward trend toward becoming Second-Level God!

At this moment, the Bloodline Power began to compress unconsciously in his chest, and a small prismatic crystal gradually began to take shape.

In just a short while, Xu Xingyu actually completed the fusion of the Mountain Dragon King Soul Bone! The entire process...
