Seeing the Bone King in front of him in this state, Xu Yang's heart was deeply touched, and he instinctively thought of his Sword of the King. When he first participated in the trial, the place where he encountered the Sword of the King was on the top of the mountain of corpses and sea of ​​blood.

The Sword of the King stands proudly in the head of the bone dragon at the top.

The huge pure bone dragon form at that time was very similar to the combat form of the Bone King in front of him.

"Haha, your current appearance reminds me of an experience in the past. In this case, let the past story repeat itself again!"

As soon as Xu Yang finished speaking, he tapped his forehead, and the sword spirit of the King's Sword that was sleeping in his body appeared again.

Now, the body of the King's Sword is not in Xu Yang's hands, but the sword spirit has not left. Instead, it chose to live in Xu Yang's soul world. Now it is summoned by Xu Yang. When he saw the Bone King in front of him for the first time, this guy couldn't help laughing.

"Boss Xu Yang, you don't need to say anything. I already understand why you summoned me. This little guy is several levels inferior to the bone dragon I killed that year."

Hearing the arrogant words of the soul in front of him, Bone King felt his face was once again greatly damaged, and immediately became extremely furious: "Who are you to dare to speak to me like this?"

The Sword Spirit of the King's Sword chuckled and said, "If we really want to count by seniority, I should be your ancestor."

“Wahahahaha!

Insightful, indeed insightful! "

When Long Kun, Ling Yao and the others heard what the Sword Spirit of the King's Sword said, they all laughed at the same time. However, the face of the huge bone dragon monster in front of them, which had already completed its transformation, was extremely pale.

"You bastards, I'm going to crush you to pieces!"

There is no doubt that after the bone dragon completed its transformation, it not only further enhanced its already extremely powerful defensive capabilities, but also greatly improved its relatively weak offensive capabilities.

The huge bone dragon's legs were constantly beating against the ground, and each movement released unprecedented impact force. Then this big guy immediately locked onto the aura of Xu Yang and the others, and swooped down and pressed forward recklessly.

"Master, do you think Bone King can escape alive from this battle?"

The Elementalist was suddenly stunned. He did not expect that the deputy beside him had completely changed his previous judgment of the battle situation. Not only did he no longer think that Bone King had any possibility of winning, he was even worried about his life and death.

Because of the strength demonstrated by Xu Yang's team and the sudden appearance of the King's Sword Soul, all of this seemed to have firmly determined the fate of the Bone King.

"Whether it's life or death, it's no longer under our control. Who made him so foolish and ignorant that he chose to confront these powerful humans with mysterious origins? This is what he deserved."

The elementalist's words meant that he was planning to stand by and watch. Even if the Bone King really died in front of them, they would never intervene easily.

In such a situation, the powerful aura firmly locked the positions of Xu Yang and the other three. Every time they took a step, the ground would shake violently like a tsunami.

To be honest, the combat power of this bone dragon is indeed very strong, but its explosive power seems to become meaningless under the guidance of the sword spirit of the King's Sword in front of it.

"From now on, the four of you, including the academy boss, must obey my command. I promise that you can use the simplest method to defeat this bone dragon!"

Of course, Xu Yang would not have any conflicts of action with the Sword Spirit of the King's Sword who jumped out to help him, and directly handed over the command of this battle to the other party.

The defense of the bone dragon lineage is so strong that it can almost withstand any elemental force and hard physical attack effects head-on. More importantly, the origin of their life is hidden in the bones. Unlike other mortal lives, they do not store energy in meridians and flesh and blood. This is the most essential difference between him and your life form, and also his greatest natural advantage.

The hardness of their bones enables this lineage to possess unparalleled powerful fighting talents on both offense and defense after transforming into combat form. Theoretically, they have no weaknesses.

However, ever since I killed the Bone Dragon with my own hands that time, I have mastered a fighting method that can suppress him as quickly as possible. Although the Bone King in front of me has a body of iron and steel without any flaws, if I can find a way to release a sufficiently powerful poison element, I can easily destroy their defense system.

Toxin is the only force that can corrode the bone dragon's solid body. According to the guidance and instructions of the Sword Spirit of the King's Sword, as long as their huge physical defense advantage is destroyed, the Bone King will become vulnerable.

Long Kun immediately spread his hands in a dilemma: "Where do you want us to get the toxin in such a barren place?

Besides, none of us has the means to control the elements."

The Sword Soul of the King's Sword did indeed smile, and looked at Xu Yang beside him with a meaningful look.

"That's right. None of you can directly control the poisonous element, but Boss Xu Yang can control the laws of the earth. All we need to do is change the shape of the earth, bring those giant scorpion poisons from the periphery into this battlefield, and use their blood to make this Bone King fall into despair."

The sword spirit's words really woke the dreamer up!

With his reminder, everyone suddenly realized what was going on. Xu Yang even smiled and attacked without hesitation. The laws of the earth were under his skilled control. The surrounding terrain features were changing wildly, causing many snakes, insects, rats and ants living in the cracks of the canyon mountains to quickly run into the center of the battlefield.

Originally, these giant scorpions had no right to show off in front of a subordinate leader like the Bone King. However, at this moment, they were pushed by the force of the change in terrain and completely gathered in the center of the canyon battlefield. A considerable number of poisonous creatures even surrounded the Bone King's location.

“Damn it!

You lowly ants, how dare you come and disturb my battle? Get out of here now, or I will kill you without mercy!"

No matter how powerful the Bone King was, the countless giant scorpions and poisonous creatures in front of him couldn't leave even if they wanted to, because the area around them had been further transformed by the subsequent laws of the earth. Sharp stone walls rose from the ground, completely confining the Bone King and these poisonous creatures in the center. At this time, they looked like a group of trapped beasts, and they no longer had any other choices.
