At the time of the emergence of this mysterious true element, earth-shaking changes were also taking place in the cloud dragon's body at the same time. The meridians and bones in its body are constantly changing and displaced, revealing a mysterious and special vein structure. The golden true yuan with a mysterious aura flowed endlessly from the various changed meridians, and gathered towards the strange vitality of the invasion in an orderly manner.

The body of the cloud dragon has been completely transformed in the magical hall, and it has almost the same physique as the real dragon. This mysterious and domineering true element is the true dragon vitality hidden and blocked in the meridians. Yunlong rarely uses it usually, but today's situation is critical, and Yunlong can't care about it so much.

"Hey, didn't you get hit by the Scattered Qi Youlan, how could you still use so many True Yuans? This breath ?????? This smell feels familiar to me. Ah, this is dragon breath, how can you have it? No, this physique doesn't look like a human being at all!Boy, who are you?" The cold Yuan Shen exclaimed.

Yunlong shouted, "Hmph! Now you leave my body now, or I'll let you go. ”

"Really? Hehe, it doesn't matter if you don't say it now. When I destroy your primordial spirit and completely take possession of your body, I will study it slowly. Now, I'll let you know that you are too far behind the old man in the use of the true element!"

As soon as the words fell, the cold body of the primordial god pinched his hands. Then the frequency of the strange True Element's operation suddenly changed, and it suddenly increased its speed by a hundredfold, and in an instant, it broke through the blocking of Cloud Dragon's True Dragon Qi and quickly attacked Cloud Dragon's Mud Pill Palace.

His face changed greatly, and through the observation of the ethereal realm, Yun Long found that the strange true elements that were about to be forced out of his body just now did not increase in quantity, but they could easily break through the defense of the true dragon's qi.

In the Mud Pill Palace, Yunlong's Yuan Shen dodged to avoid the siege of the strange True Yuan, and asked angrily and unwillingly, "How can this be?"

"Haha, boy, now you know how powerful you are! You have a lot of power, but you're not good at using it. For the sake of me that I will use your body, I will tell you some of the mysteries of it, so that you will not die blindly. Generally speaking, each cultivator has his own fixed frequency of true element operation. Of course, as its cultivation realm increases, the frequency of the True Yuan's operation will change slightly, but it won't change much. And the true element of the same quality and quantity, different use of subtlety, will produce different effects. If the frequency of your True Element can reach much higher than that of your opponent, you will be able to break through the opponent's True Element like a void. True elements with different operating frequencies have different attack effects. As far as I know, when the frequency of the True Element's operation is constantly changing according to a certain mystery, when it reaches a certain special critical point, its attack and defense power can be increased by up to ten times. For hundreds of years, the old man has realized this mystery. It's just, alas, you don't have a chance to experience it. Leng Xuan saw that the overall situation had been decided, so he said in a good mood.

"So that's the case!" After listening to Leng Xuan's words quietly, Yunlong gently closed his eyes. For a long time, he muttered.

Leng Xuan on the side saw that Yunlong was motionless, and he was not in a hurry to attack for a while.

"Alright, I'll give you one last ride. Hey hey??????" Feeling that the time was almost up, Leng Xuan sneered.

Immediately, he conjured up the magic trick and controlled those strange true elements to instantly surround the cloud dragon, trying to annihilate it in one fell swoop.

At this moment, the Yuan Shen of the Cloud Dragon, who had been closing his eyes all this time, suddenly opened his eyes, and at the same time, the golden True Yuan flashed outside itself, instantly bounced back the strange black True Yuan that was about to attack him.

"Boy, I can't see that your comprehension is so strong. In a short period of time, you can actually touch the mystery of this aspect. If you don't die today, you will become a strong man in the future. It is for this reason that I must not keep you today. Leng Xuan was stunned on the spot when he saw Yunlong's counterattack, and then said with some emotion.

The magic trick changed again and again, and the strange true element constantly changed its running frequency, attacking the cloud dragon with all its might. Recognizing the terrible potential of his opponent, Leng Xuan no longer underestimated Yunlong and began to take it seriously.

With the help of superhuman comprehension and the wonderful ethereal realm, Yunlong was able to barely keep up at first, and he was still able to resist for a while.

It's just that as time goes by, Yunlong gradually feels powerless. Knowing that it was only a matter of time before he was destroyed today, Yunlong couldn't help but show a deep sense of loss and sadness on his face. I just found my grandfather, if I die like this, who will take care of my grandfather, and who will avenge my parents' hatred?

What Yunlong didn't know was that Leng Xuan's heart was even more turbulent at this time, and it was extremely uncalm. With hundreds of years of comprehension, he has used hundreds of changes in the true element frequency one after another, and the other party has just touched a little fur, and he can barely match himself.

Such a young boy, but he has an almost demonic comprehension talent. While Leng Xuan felt that he was inferior to the other party, he strengthened his determination to get rid of this person.

Calming down his uncalm emotions, Leng Xuan no longer had the slightest reservation at this moment, and used his true yuan with all his strength to launch a fierce attack on Yunlong.

Finally, after half a quarter of an hour, the cold extinction finally shrouded the primordial spirit of the cloud dragon in one place, and the black true essence was circulating endlessly, refining it with all its might.

Seeing that the struggle was fruitless, Yunlong simply gave up resisting, gently closed his eyes, and Yunlong sat cross-legged. On the verge of life and death, Yun Longxin was surprisingly at a calm he had never had. At this moment, Yunlong first thought of his grandfather, parents, Liu Yuan, Yue'er and Ruoyu, and made the last silent blessing to them in his heart.

Finally, a beautiful shadow suddenly appeared in my mind, beautiful and sacred, elegant as a fairy, it was the clear moon.

Somehow, when he thought of her, Yunlong's already relieved and calm state of mind actually made waves, feeling a little hurt, a little unwilling and reluctant. Could it be that he is really in love with her? It's a pity that creation makes people, Yun Long shook his head a little bitterly.

When all the distractions in his heart were thrown away, Yunlong was suddenly pleasantly surprised to find that the divine dragon jade pendant on his body had changed again. With some expectations, Yunlong closely observed the changes in the Divine Dragon Jade Pendant.

I saw that the unknown patterns and ancient characters around the jade pendant began to rotate slowly. When he rotated nine times, he saw that the divine dragon in the middle of the jade pendant suddenly burst into golden light.

The change of the jade pendant also alarmed Leng Xuan, who was refining the Yunlong Yuan Shen, and for no reason, Leng Xuan suddenly felt a little uneasy. At first, his brows furrowed, and then a small ball of black light shot towards the place where the jade pendant was.

About a foot away from the jade pendant, a dragon roared suddenly in the jade pendant, and a golden light popped out and retracted like lightning, engulfing the black ball in an instant.

The cold Yuan Shen was suddenly startled in his heart, and was about to make a move, but he found that the golden divine dragon embedded in the middle of the jade pendant roared in his mouth, and opened his mouth to emit a ray of light, enveloping the dull Buddha bone relics in the distance that fell into the stone wall of the cave.

Leng Xuan suddenly panicked in his heart, and the uneasiness in his heart became stronger and stronger. Before he could stop it, he saw that the relics suddenly shone brightly, and returned to their previous sacredness and light. Immediately, in a cold and frightened gaze, it shot into Yunlong's body. Quickly swam along the veins of the Yuan Dragon, eliminating all the black strange true elements that had invaded all parts of the Yun Dragon's body, and finally entered the Cloud Dragon's Mud Pill Palace.
