Su Yu was grabbed by the neckline by the crazy old man, his neck was strangled tightly, and it was a little difficult to breathe, but the crazy old man was getting tighter and tighter, and Su Yu, who was straight card, was very uncomfortable.

The crazy old man approached Su Yu, and a pair of eyes kept looking at Su Yu, as if he could find out the essence of the hundred fires.

"Hundred Fire Essence...... Sword ......" The mad old man began to talk to himself, as if comparing the two to see which was more important.

"Ahem...... Old man, can you please let the kid down first. Su Yu was strangled by the crazy old man, and the crazy old man never showed any signs of letting go of him, but fell into thinking, if Su Yu didn't remind him, he was afraid that when the crazy old man remembered, he would be strangled to death.

"Oh. The crazy old man responded with a pretentious voice, stayed for a long time, and then let go of his hand without warning and put Su Yu down.

"Poof!"

Su Yu fell down in an instant, and his buttocks hit the ground heavily, as if he had been broken into several pieces.

"Hiss......" Su Yu bared his teeth, and the tail vertebrae were particularly painful, so he rubbed it vigorously to make it better.

"I'll give you the sword, and you'll be able to give me the Hundred Flames Essence?" the crazy old man asked with a tentative expression.

"That's right, if you return the sword to me, I will give you the Hundred Fire Essence, and exchange the sword for the Hundred Fire Essence. Su Yu nodded affirmatively, at least that's what the machine spirit passed on to him.

"That'...... Give me this sword! Give me the essence of the hundred fires. The crazy old man struggled for a long time, chose the Hundred Fire Essence, which was more precious than this rusty sword, and presented the rusty sword in front of Su Yu.

"Thank you, old ......" Su Yu subconsciously went to pick up the Traceless Sword, thanks to the old man, the five words were only halfway through, and before his hand touched the Traceless Sword, the crazy old man quickly took the Traceless Sword back.

"Don't think I don't know what your kid has in mind, I want to take the sword away before I give it to me?" Hmph......" The crazy old man glanced at Su Yu, looking like you don't want to take the sword without handing over the Hundred Fire Essence, his expression was very arrogant.

Su Yu couldn't cry or laugh, the crazy old man was quite thoughtful, what was the difference between this and lying to him?

Even if he got the Traceless Sword, the spiritual power in his body has not recovered much now, and even the spiritual power of the Edgeworth's flight is not enough, so he is afraid that he will be caught by the crazy old man before he runs far.

"Su Yu, you drag him down, when the spiritual power in the body is restored to the best, and when the original spirit will exchange it with the Hundred Fire Essence with him. The voice of the machine spirit sounded in Su Yu's mind again.

"Hahaha, does the machine spirit of a dignified immortal weapon also use such methods?" Han Qi suddenly spoke, unabashedly mocking, and sneered at the machine spirit.

"Hmph, you don't need to care about how the spirit acts, let you hand over your life essence, are you willing?" the machine spirit also scoffed, it didn't believe that Han Qi could do it.

"Hmph! What he wants is not the life essence of the deity, but the essence of your hundred fires! Besides, you proposed it yourself, what does it have to do with the deity?"

"What does this spirit do to you, don't forget the contract on your body, if this crazy old man doesn't let Su Yu go, you won't be much better. The machine spirit glanced at Han Qi coldly and reminded it.

"Hmph!" Han Qi snorted coldly, and said no more, this damn contract would have to be broken one day by him.

From the moment the voice of the two appeared, Su Yu knew that the machine spirit and the machine spirit were going to ridicule each other again, so he took the initiative to ignore the argument between the two, and he had long been accustomed to it.

"Old man, I don't mean to take the sword away and not give you the Hundred Flame Essence, it's just that I need a little time to take out the Hundred Fire Essence again, and it's not too late for you to give me the sword when the time comes. Su Yu explained to the crazy old man, according to the meaning of the machine spirit, to gain time, and then restore the spiritual power in the body to the best.

"Okay, when you take out the Hundred Fire Essence, I will give you the sword when you want. "The crazy old man is very talkative, he is sure that if he has a sword in his hand, he will definitely be able to exchange for the essence of the hundred fires.

"Okay!" Su Yu agreed, then sat down, ran the basic exercises, and recovered his spiritual power with peace of mind.

As soon as the basic exercises were running, the surrounding spiritual power suddenly surged towards Su Yu's body, but the spiritual power in the mountains and dense forests was much thinner than that on Tangmen Peak, but even so, the spiritual power in Su Yu's body was still growing rapidly.

The crazy old man just stared at Su Yu and used the exercises to restore his spiritual power, and Su Yu's breath gradually became stronger, but it was much worse than the crazy old man, and the crazy old man didn't take Su Yu's strength in his eyes at all.

Su Yu fought for the fate to turn the basic exercises, quickly recovered his spiritual power, and the hunger for spiritual energy in the meridians was also satisfied, greedily absorbing the spiritual energy, and transforming it into spiritual power and storing it in the dantian.

Su Yu looked like a bottomless pit absorbing aura, and the aura in the forest continued to converge around Su Yu's body, but Su Yu didn't seem to be able to absorb enough.

"Yawn ......" The crazy old man stared at it for a long time, his eyes were a little blurry, he couldn't help yawning, sat down casually on the spot, and looked at Su Yu tightly with the Traceless Sword in his arms, not even looking for the immortal vine.

After about an hour and a half, Su Yu's absorption of aura gradually slowed down, and the aura around him gradually dissipated, and the crazy old man who had been staring at it saw the aura slowly dissipating, his eyes lit up, he was sleepy, and his expression suddenly became energetic.

"Okay?" The crazy old man walked into Su Yu with a rusty sword, he knew that Su Yu was recovering his spiritual power just now, presumably he couldn't take out the Hundred Fire Essence without spiritual power, so he let Su Yu go, besides, Su Yu only had the strength of the Spirit Realm, and he couldn't make much waves in front of him.

"The Hundred Flame Essence is here, can the senior give me the sword?" A ball of brilliant flames appeared in front of Su Yu again, slowly burning, and bursts of burning sensation came to his face.

The machine spirit controlled the Hundred Fire Essence to slowly float in front of the crazy old man, and the crazy old man spoke and threw the Traceless Sword to Su Yu.

"Here you go!"

Su Yu hurriedly caught it, and after going around for so long, he finally took back the Traceless Sword from the crazy old man, but a bad premonition rose in Su Yu's heart.

"Su Yu, hurry up the sword! After a while, the original spirit will take back this hundred fire essence, and you can fly as fast as you can!" Sure enough, Su Yu's hunch was right, and the unreliable voice of the machine spirit sounded in Su Yu's mind.

Su Yu's head was big for a while, and there was no other way, so he hurriedly retreated from the crazy old man for a distance, silently recited the swordsmanship mantra in his heart, and watched the crazy old man's movements vigilantly.

"Whew!" Su Yu jumped on the Traceless Sword, and the swift Edgeworth flew out of this dense forest, and then flew forward desperately.

Su Yu suddenly flew away from the sword, which made the crazy old man stunned, and he didn't chase after him, but thought that Su Yu thought he was going to grab his sword, so he ran away.

The crazy old man turned his head and looked at the hundred fire essence in front of him, at this moment the hundred fire essence was floating in the air, slowly blooming and burning, looking at this mass of hundred fire essence The crazy old man's eyes were full of coveting, but the temperature of the hundred fire essence was quite high, how to collect this hundred fire essence made the crazy old man difficult.
