Because Kong Yu and the sword demon Dugu are both performing the Dugu Nine Swords, there will naturally be no difference between superior and inferior in swordsmanship, and although Kong Yu is not as familiar with the Dugu Nine Swords as the Sword Demon Dugu Mouru, he is slightly better in terms of skills, so for a while, the two are also a little equal, and it is difficult to distinguish the winner from the loser.

The battle between the two has been going on, fighting hard again and again, and the giant sword turned into by the two people is moving faster and faster, and finally I just saw two rays of light circulating, and I couldn't see the giant sword turned into by the two people at all, and the mana that erupted from the two people was becoming more and more intense.

Kong Yu originally thought that as long as he insisted on not falling behind in swordsmanship, then he would definitely be in an invincible position, after all, Kong Yu's mana was deeper than that of Sword Demon Dugu, in this way, as long as the mana of Sword Demon Dugu was consumed, then victory would naturally belong to Kong Yu.

It's just that what Kong Yu didn't expect was that although the mana of Sword Demon Dugu seemed to be only at the realm of the middle stage of Xuan Xian, there was no sign of mana exhaustion since the war like him, which made Kong Yu very puzzled, and didn't understand what was going on, could it be that Sword Demon Dugu was also hiding his strength?

Because Kong Yu is cultivating the Nine Turns Xuangong, his strength is hidden in the body, so that he can hide his strength, but Dugu is obviously not practicing the Nine Turns Xuangong, and what method is used to hide his strength? This makes Kong Yu puzzled, and in the end, Kong Yu finally discovered the mystery, and the reason is on the rusty iron sword that the sword demon Dugu seeks defeat.

Sword Demon Dugu does not have hidden strength, but his mana can always be maintained in the realm of the middle stage of Xuan Xian, and there will be no consumption, so that he can fight with Kong Yu for such a long time, and being able to do such a point is the credit of the iron sword in Sword Demon Dugu's defeat.

Originally, Kong Yu thought that the rusty iron sword in the sword demon Dugu's hand was a very ordinary, the cheapest iron sword used by mortals, but now it seems that this is not the case. Also, how can an iron sword that can enter the Sword Demon Dugu's Defeat Eye be mortal!

And this iron sword, which looks the cheapest, doesn't look very sharp, but the sword qi emitted can easily tear through the void, and absorb the vitality of heaven and earth all the time, and then transform it into the mana of the sword demon Dugu to seek defeat, supplementing the mana consumed by Dugu's defeat, so that Dugu's mana has always been maintained in the realm of the middle stage of Xuanxian, which makes the sword demon Dugu be able to fight with Kong Yu for so long.

Kong Yu, who discovered this, was secretly surprised in his heart, if he was not a balanced body of the five elements, extremely sensitive to the vitality of the five elements of heaven and earth, and did not find out about this matter, then he would continue to fight like this, and if he waited until his mana was all consumed, then he would become meat on the chopping board.

Kong Yu knew that he would definitely suffer a loss if he continued like this, so he no longer had any reservations, and raised all his mana little by little, under the huge mana infusion, the giant sword of Kong Yu's incarnation condensed a lot again, and the power that emanated made the space around the giant sword distorted, and then a crackling sound sounded around Kong Yu's incarnation of the giant sword, and it turned out that the surrounding space could not withstand the huge pressure and shattered.

"Good boy, it turns out that he really hides his strength, just waiting for you!" The voice of the sword demon Dugu seeking defeat sounded in the heaven and earth, and there was a faint excitement in his voice, as if he had long expected that Kong Yu was still hiding his strength, and he had been waiting for Kong Yu to show all his strength.

Kong Yu felt a pang in his heart after listening to the words of Sword Demon Dugu, he didn't expect that this Sword Demon Dugu would be able to know that he still had hidden his strength, but then he was relieved. With the insight of Dugu seeking defeat, it is naturally easy to know that he has hidden his strength, so there is nothing to be surprised about.

And after the Sword Demon Dugu was finished, he stopped, and gradually lifted the state of turning into a sword with his body, and seeing such a situation, Kong Yu naturally did not think that the Sword Demon Dugu was not fighting with him, and was going to stop, but made Kong Yu's heart more solemn, because Kong Yu knew that the next thing was the true essence of the Sword Demon Dugu's defeat.

This made Kong Yu a little nervous and a little expectant, the previous battle with the sword demon Dugu to defeat had already made Kong Yu's comprehension of Dugu Jiujian more profound, and the experience of martial arts had improved a lot, but he was even more looking forward to the next action of the sword demon Dugu seeking defeat.

I saw the rusty iron sword in the hand of the sword demon Dugu throwing it into the air, and then pointed out, and a sword qi shot out from the fingertips of the sword demon Dugu and pointed at the iron sword, and then I saw that the iron sword exploded, turned into a ball of powder, and gradually disappeared between heaven and earth.

This action made Kong Yu feel a little incredible, and he didn't understand what the Sword Demon Dugu was trying to do, but what Kong Yu saw next made him feel shocked, because he saw that the Sword Demon Dugu was defeating and turned the iron sword into powder, and scattered it between heaven and earth, and then Kong Yu actually felt the vitality between heaven and earth fluctuate violently.

The surrounding tens of thousands of miles of heaven and earth vitality rushed violently towards the place where the Sword Demon Dugu sought defeat, and then it condensed at an extremely fast speed, and finally formed a three-foot long sword, suspended around the Sword Demon Dugu's defeat, and in the blink of an eye, tens of millions appeared, and they were still spreading endlessly.

Kong Yu's heart was shocked, this turned out to be the realm of the legendary Heaven and Earth All Things Sword in Dugu Nine Swords, I didn't expect the sword demon Dugu to seek defeat actually reached such a realm, looking at the long sword condensed with the vitality of heaven and earth, Kong Yu's admiration for the sword demon Dugu in his heart was simply incomprehensible.

It's just that Kong Yu also discovered that the realm of the Sword Demon Dugu Seeking Defeat is not perfect now, because Dugu also uses the power of the iron sword, and now it is only to the point where the Heaven and Earth Yuan Qi can be condensed into a sword, and it has not achieved the realm of the Heaven and Earth Everything.

But even so, it made Kong Yu extremely cautious in his heart, because at this time, the momentum emanating from the sword demon Dugu's body was even more huge, and Kong Yu knew that his attack would be more intense next!
