After rushing out of the dense forest, Su Yu flew quickly with the sword, exerting all the spiritual power in his body on the Traceless Sword, and flew towards the direction of the Human King City at the fastest speed, and soon, Su Yu's figure turned into a small black dot in the air, getting farther and farther away from the dense forest.

The crazy old man was still staring at the mass of Hundred Fire Essence in front of him, and under the high temperature of the Hundred Fire Essence, all the plants and trees within three miles of him were burned into black scorch, and the range continued to expand.

"How do you put it away? I knew I shouldn't have let that kid run away just now......" The crazy old man circled around the Hundred Fire Essence several times, scratching his ears and cheeks, and he didn't know what to do.

"Poof!"

Suddenly, there was a soft sound, and the Hundred Fire Essence seemed to be blown by a gust of wind and extinguished it.

A wisp of green smoke came out from the place where the Hundred Fire Essence was suspended just now, rising into the air and gradually dissipating......

"Hmm, why is it gone!" the crazy old man was startled, and ran to the place where the Hundred Fire Essence was suspended, grabbing it in the air with both hands, thinking that in this way he could catch the Hundred Fire Essence in his hands.

However, the crazy old man only grabbed it in the air, but he didn't catch anything, and the Hundred Fire Essence disappeared without warning, leaving no trace.

"Ahhh

The crazy old man didn't say that he was going to continue looking for the immortal vine, so he directly volleyed up in the air and chased in the direction Su Yu left.

Hundred Fire Essence is the only one in the world, rare in the world, compared to the Immortal Vine, the weight is not bad at all, anyway, he didn't find the Immortal Vine, and he couldn't find the Immortal Vine for a while, it is better to get the Hundred Fire Essence that he has seen with his own eyes, and more importantly, he must grab the kid who dared to deceive him and tear it apart with his own hands!

"Su Yu, the Hundred Fire Essence has been taken back by me, that crazy old man loves rare things so much, I guess he will definitely catch up, and the rest is all up to you. The voice of the machine spirit sounded in Su Yu's mind, and the machine spirit hurriedly finished speaking without squeaking.

"Senior Machine Spirit, why don't you collect it later!" Su Yu wanted to cry without tears, he only flew out for more than ten miles, and the Machine Spirit said that he would take back the Hundred Fire Essence for a while, and thought that he could wait until his Imperial Sword flew out for a long distance, but he didn't expect that the Machine Spirit would take back the Hundred Fire Essence so quickly.

According to the strength of that crazy old man, if he really catches up, it won't be long before he will be caught up, and he won't be able to run away if he wants to!

"You've already flown out more than ten miles away, and if it's too late, you won't be able to get it back and really give it to that crazy old man, and the spirit can't do it even if you want to be late!" The machine spirit explained in the sacrificial space that it was already its limit if it was delayed for so long, and if it was placed at its peak, it could be easily recovered thousands of miles away, but it was a pity that this time was different from the past, and it could only be like this.

"Okay......" Su Yu was helpless, and increased the speed of the imperial sword to the extreme, I just hope that the crazy old man won't catch up!

Su Yu's idea is good, but can reality really make him happy?

The figure of the crazy old man quickly chased after him from behind, his strength was already enough to volley in the air, and he didn't know how much faster than the speed of Su Yu's imperial sword.

"Su Yu, hurry! That crazy old man catches up, not far ahead is Lincheng, and when you arrive at Lincheng, the spirit guarantees that the crazy old man will never find you!" "The machine spirit always reminded Su Yu that it was a matter of time before the crazy old man caught up with Su Yu, but as long as Su Yu could reach Lincheng before the crazy old man caught up, it would have a way to protect the crazy old man from finding Su Yu, but before that, it would depend on whether Su Yu could fly past the crazy old man.

Once the mad old man is more energetic, the machine spirit can foresee the scene when the crazy old man chases Su Yu all the time.

"Why is it so fast?" Su Yu couldn't help but glance back, and sure enough, a small black dot was rapidly approaching him, and it was getting closer and closer to him, and he could faintly see the figure of the person coming, it was the crazy old man!

"Senior Machine Spirit, how far is it to get to Lincheng?" Su Yu asked in his heart, he didn't know how far ahead the Machine Spirit said, how many miles away Lincheng was, if it was too far, he wasn't sure that he would be able to reach Lincheng before the crazy old man caught up.

"It's probably more than thirty miles!" Ji Ling estimated in his heart and told Su Yu that this result was not too good.

"Three...... More than thirty miles!I'll go!" Su Yu couldn't help but burst into a foul mouth, and he only felt that there were countless sheep running wildly in his heart!

He ran more than ten miles ahead of time to get rid of the crazy old man, and he was about to be caught up by the crazy old man at a distance of less than twenty miles in total, and there was still a distance of more than thirty miles in Lincheng, no matter how you look at it, it was a little hanging!

"You hurry up, it's only thirty miles, and it's another story if you can catch up. The machine spirit cheered Su Yu up, in fact, he himself was only a little sure, whether he could not be caught up by the crazy old man still depends on Su Yu's own luck.

"Senior, I'm already fast. Su Yu smiled bitterly, this is already the limit of the spiritual power in his body that can be output, he wants to go faster, but the meridians in the body will definitely not be able to withstand it, such a crazy sword, the meridians in the body have faintly shown some signs of being cracked, this is the embodiment of the extreme speed of the spiritual power in the body, once this limit is exceeded, the meridians in the body will burst.

"There are still thirty miles to Lincheng, and the crazy old man is no more than ten miles away from you!" The machine spirit continued to estimate the distance between the three, looking at the crazy old man who was getting closer and closer, Su Yu was a little anxious.

"Hmph, boy, the old man advises you not to run away, you can't run away! You kid dares to lie to the old man, when he catches you and gets the essence of the hundred fires, the old man will definitely tear you into several pieces!" In the rear, the crazy old man volleyed in the air at an extremely fast speed, almost twice as fast as Su Yu, and shouted at Su Yu in the rear.

"If you don't run, if you don't run, you'll be torn into a few pieces!" Su Yu scolded in his heart, who would be stupid and wait for the crazy old man to catch up and be torn into a few pieces?

Su Yu ignored the crazy old man, gritted his teeth and used the spiritual power in his body even more frantically, and the speed of the Traceless Sword under his feet suddenly accelerated a little!

The feeling that the meridians in the body are bursting is getting stronger and stronger, the toughness of the meridians has been stretched to the maximum limit, and the spiritual power in the body is desperately infused into the traceless sword, and the meridians are constantly tearing, and it seems that they will burst open at any time!

"No, hurry up!" Su Yu glanced at the rear, the distance between the crazy old man and him was no more than five miles, and there were still more than twenty miles in Lincheng, the distance of twenty miles was not long, it was not short, while the crazy old man was still five miles away from him, he still had a chance to fight!
