Proof

As soon as Xu Xingyu jumped into the Ice and Fire Yin Yang Well, she immediately felt the erosion from the two extreme elements of Ultimate Ice and Ultimate Fire.

However, just as the two elements were about to wreak havoc on Xu Xingyu 'Xu Xingyu body, a cyan light enveloped her, preventing the threatening ice and fire power from corroding Xu Xingyu.

This cyan light is the power of the Ultimate Wind.

As the reincarnation of the Dragon God God's son, Xu Xingyu naturally inherited the Dragon God's power to control multiple elements. This means that every ten levels of Dragon God Martial Soul, after obtaining a Soul Ring, a new ultimate element will be unlocked.

Xu Xingyu has just reached level 41, is already able to use water, fire, wind, and the newly unlocked earth element due to the self-generated Soul Ring of the Dragon God Martial Soul.

Xu Xingyu is currently using the Ultimate Wind element as something similar to a spacesuit to protect herself from any harm caused by the extreme elements in the Ice and Fire Spring.

After setting up protective measures, Xu Xingyu began swimming towards the bottom of the Ice and Fire Spring. After an unknown amount of time, Xu Xingyu finally arrived at the place he was looking for.

Before Xu Xingyu appeared two colossal corpses, each a thousand meters tall. These two corpses were in the shape of dragons and exuded a powerful aura, as if proclaiming how powerful their owners had once been.

Judging from the various signs before us, this is the burial place of the Ice and Fire Dragon Kings, and also the origin of the Ice and Fire Yin Yang Well.

Looking at the two dragon corpses that had begun to lose their spirit, Xu Xingyu couldn't help but sigh. This outcome was within his expectations.

After all, after obtaining the dragon pearls from the Dragon Soul of the two great Dragon King, Xu Xingyu vaguely sensed that this was a kind of entrustment of her orphanage.

After the two Dragon Soul dissipated, the energy within these two dragon corpses is also rapidly dissipating in a special way. Without the support of the Dragon Soul, these two dragon bones will likely completely dissipate in the human world in a few hundred years, turning into nourishment for this Ice and Fire Spring.

However, before that, Xu Xingyu had one more thing to do: find the Soul Bone left behind by the Ice and Fire Dragon Kings.

Before Xu Xingyu's first incarnation Starry Dragon Emperor was born, his father Dragon God, had promised to select Dragon God from among the Nine Great Dragon Kings. However, his birth caused many problems.

The Dragon God made this choice because he never intended to have children with his wife. He believed that his own bloodline was too powerful and would cause his wife to suffer a difficult childbirth due to the inability to withstand the power of the Dragon God Bloodline.

Therefore, when his wife secretly became pregnant with the Starry Dragon Emperor and suffered a difficult childbirth, the Dragon God was devastated.

Although he tried his best to save his wife's life, he only managed to save the dragon eggs she laid.

This dragon egg eventually hatched into the Starry Dragon Emperor.

Since the existence of the Starry Dragon Emperor was completely unplanned, yet he was the best successor to the Dragon God, the Dragon God, in order to avoid dissatisfaction among the Nine Great Dragon Kings, declared that if the Starry Dragon Emperor wanted to inherit the Dragon God Position, he must gain the approval of the other Nine Great Dragon Kings.

Otherwise, the final successor to the Dragon God would only be chosen from among the Nine Great Dragon Kings, which dispelled the dissatisfaction of those Dragon King who had long wanted to inherit the Dragon God Position.

This rule was a vow made by the Dragon God to the Universal Consciousness, therefore Xu Xingyu must still act in accordance with this rule in this life.

The best proof for the Nine Great Dragon Kings is to obtain the Soul Bone they produce. This is why Xu Xingyu went to great lengths to obtain the Soul Bone of the Nine Great Dragon Kings, as these are essential for him to inherit the Dragon God Position.

Currently, Xu Xingyu only possesses the left palm bone produced by the Dark Dragon King, which is still some distance from her goal of collecting all the Soul Bone of the Nine Great Dragon Kings.

Soon, Xu Xingyu used her powerful Spiritual Power to locate the Soul Bone of the two Dragon King.

After all, it's not too difficult. As long as you find the bone that contains the most energy, it's almost certainly Soul Bone.

However, to Xu Xingyu's dismay, the Soul Bone produced by the Ice and Fire Dragon Kings were actually a right arm bone and a left leg bone, the former produced by the Fire Dragon King and the latter by the Ice Dragon King.

Xu Xingyu knew that these two people disliked everyone in life, but was it necessary for their Soul Bone to remain the same after death?

Generally speaking, if a person first fuses with a limb-type Soul Bone, then their second Soul Bone should ideally be a limb corresponding to that Soul Bone.

For example, if you fuse your right arm bone first, it's best to fuse your left arm bone next, because this will maintain the energy balance in your body and prevent conflicts when absorbing the second Soul Bone.

However, this is not necessary, but it is the best option. If Soul Master has strong enough control over their body and Soul Power, then they can completely ignore this issue.

Moreover, Xu Xingyu is not considering this option right now, not only because he needs the Soul Bone of the Nine Great Dragon Kings as proof, but also because when Xu Xingyu discovered the two Soul Bone, those two Soul Bone also discovered Xu Xingyu.

Two pieces of the Dragon King's Soul Bone rushed towards Xu Xingyu and began to actively merge with Xu Xingyu.

As the extreme power of ice and fire raged through her body, Xu Xingyu felt an unprecedented pain.

If I had to use a metaphor, it would be like someone first splashing hot water on your bleeding wound, then splashing cold water, and then repeating this process over and over again.

The last time Xu Xingyu felt such pain was when he suffered the aftereffects of merging with the Golden Dragon King's divine essence in the Far North.

In response, Xu Xingyu had to use the Chaos Qi in the Pseudo-Chaos Core to calm the two conflicting elements and prevent them from starting a battle for control within his body.

However, this approach could not alleviate Xu Xingyu's pain. On the contrary, because Xu Xingyu needed to divert some of his energy to regulate the extreme ice and fire elements, he could only open his meridians to allow the energy in the Soul Bone to directly cleanse his body.

Undoubtedly, this is a very dangerous act. It is true that the speed of energy absorption will be greatly accelerated in this way, but because the process of neutralizing the violent molecules in the energy is missing, the pain that Xu Xingyu has to endure will increase exponentially.

At the same time, the slightest carelessness could result in the complete severing of all meridians.

The reason Xu Xingyu dared to allow the Dragon God Bloodline to modify his body was that the Soul Bone of the two Dragon King, upon sensing the Dragon God Bloodline within Xu Xingyu's body, autonomously restrained themselves and at least protected Xu Xingyu's meridians.

Therefore, Xu Xingyu can only passively endure the pain of fusing with the Soul Bone, hoping that nothing unexpected will happen during the process.

However, things did not go as planned. After an unknown amount of time, just as the fusion of the two Soul Bone was about to be completed, Xu Xingyu's Pseudo-Chaos Core began to emit an unstable fluctuation.

An event that Xu Xingyu will never forget is about to happen.
