After being happy for a while, Zhu Xuanchen suddenly found that he couldn't get down at all, how could he get the fire core, and hurriedly asked Emperor Xuanhuang for advice: "I can't get close, how can I take the fire core back into the Xuanyuan Sword?"

"Now that the Xuanyuan Sword has collected the three major attribute cores, if you use the power of the Xuanyuan Sword to feel the exact location of the fire core, you should be able to forcibly introduce the fire core into the Xuanyuan Sword, you can try it." Emperor Xuan said after thinking for a while.

"That's all there is to it. After speaking, Zhu Xuanchen slowly closed his eyes, held the Xuanyuan Sword tightly with both hands, and began to experience the vague connection between the Xuanyuan Sword and the fire core.

Zhu Xuanchen closed his eyes, and after inducing the Xuanyuan Sword with all his heart, a magical picture appeared in his mind, he saw the Xuanyuan Sword in his hand unveil layer after layer of mystery in front of his eyes, I don't know how long later, as the last fog dispersed, he saw three energy clusters that emitted dazzling light, the colors of these three rays were green, gold and light blue, and he could see at a glance that this was the gold, wood, and Ice core, he didn't feel strange about this, to his surprise, these three energy groups were surrounding a motionless bone dragon, only white bones remained, although only the bleak white bones remained, but Zhu Xuanchen could still feel a self-respecting arrogance on his body, and the three cores with vast energy could only bow down to it, this scene made Zhu Xuanchen feel that the Xuanyuan Sword must have some kind of connection with the legendary dragon, and made him more and more convinced that the dragon really existed, temporarily putting aside these thoughts, he carefully observed the bone dragon and the three cores again, and under patient observation, he finally saw a very vague and looming light between the bone dragon and the fire coreAlthough I have seen that there is indeed some kind of connection between the bone dragon and the fire core, what should I do next?

After thinking for a while, Zhu Xuanchen decided to inject some Xuanyuan Gang Qi into the bone dragon to try, maybe he could strengthen the connection between the bone dragon and the fire core, so as to use the bone dragon to recall the fire core back into the Xuanyuan Sword.

After taking a deep breath, Zhu Xuanchen was nervous, and slowly transported some Xuanyuan Gang Qi to the bone dragon, he didn't know if something good or bad would happen next, but he had to get the fire core as soon as possible to improve his strength, time waited for no one, and no one knew when Li Fengzi would attack again.

The moment the bone dragon came into contact with Xuanyuan Gangqi, the bone dragon that was originally motionless actually moved, although the movement was a little stiff, but it did move in front of his eyes, but this bone dragon was wandering aimlessly in the Xuanyuan Sword with the three cores, and he had no intention of helping him at all.

Zhu Xuanchen thought secretly, "Maybe I need to tell it with my mind, what should it do?"

Thinking of this, Zhu Xuanchen once again re-transmitted Xuanyuan Gang Qi to the Bone Dragon, but this time the Gang Qi was accompanied by his thoughts, ordering the Bone Dragon to forcibly recall the fire core.

At first, the bone dragon obviously showed disobedience, but Zhu Xuanchen would not give up, and constantly imposed his mind to order the bone dragon to obey, after a period of tug-of-war, the bone dragon could not resist Zhu Xuanchen's imposition after all, only to see the bones of the bone dragon open its mouth, as if it was making a silent dragon groan, in the process of the dragon groan, the three cores turned into an iron chain between the bone dragon and the fire core, strengthening the connection with the fire core, and also locking the fire core, and then the bone dragon tightly grasped the end of the iron chain with the five claws of its arm, and the body danced to pull the fire core back little by little。

The fire core had already absorbed a lot of energy in the volcano, and its spiritual intelligence had recovered far more than the previous three cores, how could it be willing to leave this environment full of fire attributes that made it feel very comfortable and return to the Xuanyuan Sword? So the fire core was determined to fight against the bone dragon, and tried its best to pull the chain back.

The fire core has been recuperating in the volcano for a long time, and its strength is no weaker than that of the bone dragon, and after some pulling, the bone dragon has fallen into a disadvantage, and the iron chain in his hand is pulled back by the fire core little by little.

Zhu Xuanchen soon discovered this, and immediately went all out to inject the majestic Xuanyuan Gang Qi into the bone dragon, with more Xuanyuan Gang Qi, the bone dragon not only had stronger strength and vitality, but also stimulated its innate arrogance, the little fire core actually dared to resist it, with anger and the powerful power just obtained, the bone dragon let out a silent roar to counterattack the fire core.

With Zhu Xuanchen's continuous supply of energy, the fire core naturally couldn't last long, and it was only a matter of time before he gave up resistance, and soon the ruby-like fire core was pulled out of the magma range by the bone dragon, leaving the magma range, the resistance of the fire core was even smaller, and the bone dragon burst out with all its strength, instantly pulling the fire core into the Xuanyuan Sword, and the fire core really melted into the Xuanyuan Sword.

After the ruby-like fire core was integrated into the Xuanyuan Sword, the temperature of the surrounding environment dropped by dozens of degrees at once, Zhu Xuanchen also slowly opened his eyes at this time, held the Xuanyuan Sword in his right hand and raised it to his eyes, and saw that the cracks on the sword body were emitting fiery red light, and the cracks that the light passed through would be as good as ever, and everything calmed down, and only a small part of the tip of the sword was left on the Xuanyuan Sword that had not yet recovered, although it was a small part of the Xuanyuan Sword, it was also the most important part, if the sword was not sharp, how could it be sharp?

But Zhu Xuanchen didn't have time to find the last thunder core, and he didn't even have a spectrum in his heart where the thunder core might exist, so naturally he could only dispel this idea for the time being.

Putting aside unrealistic ideas, Zhu Xuanchen picked up the Xuanyuan Sword, his mind moved, the blade of the Xuanyuan Sword was immediately covered by a layer of red fire, this thick layer of fire, making the entire sword body look twice as large as the original, Zhu Xuanchen gently waved the Xuanyuan Sword, no matter how much strength he wielded, the fire was still unabated, the air was burning everywhere he passed, leaving a little spark in the air, suddenly he turned around quickly, a sword slashed obliquely on a boulder, and in a moment the upper part of the boulder slipped down, and the place where it was cut was as if it was passed by hot lava, and most of the stone was melted by the high temperature。

Looking at the effect of the fire core on the Xuanyuan Sword, Zhu Xuanchen smiled with satisfaction, turned his head to look at He Yan with a surprised expression in the distance and said, "Senior He, I'm sorry for keeping you waiting, let's go to Xuanmen now." ”

He Yan came back to his senses, took a deep breath and said, "It seems that it is really as Senior Zhang said, except for you, there is no one more suitable than you to challenge Li Fengzi's kid, I completely believe you." ”

"Thank you seniors for your trust, let's go, Senior Li is waiting outside in a hurry. Zhu Xuanchen said with a smile.

He Yan nodded his head, and the two walked out quickly.
