The dark night was like water as darkness enveloped the Tower of Slaughter. The restaurant was brightly lit and the brothels became lively. Many martial artists entered and left to relieve the pressure and vent the fire in their hearts.

"I really don't know what sort of almighty elder refined this Tower of Slaughter. The interior of this tower is actually the same as the outside world, with its own space. It has day, night, sun, moon, stars …" Ye Zichen couldn't help but sigh as he looked at the layers of clouds that obscured the moon and stars in the sky.

He also had a feeling that the Tower of Slaughter itself was a treasure, and its rank was beyond his imagination.

Under her disappointed gaze, he walked up to an ancient sandalwood chair by himself. He closed his eyes and rested, waiting for the private fair to begin.

While Ye Chenfeng was waiting with his eyes closed, he suddenly felt a sharp killing intent lock onto him with his sharp senses. He opened his eyes and noticed a tall and sturdy figure wearing a dark purple long robe, Forest Thunder, whose entire body was filled with a violent aura, appearing in the trading center, staring at him with a sinister gaze.

"Forest Thunder!"

Ye Chen did not expect to meet Sen Lei here, so he frowned.

"Ye Zichen, I never would have thought that we'd meet again so soon." Sen Lei, the overlord of the fourth floor, opened his mouth and revealed a mouthful of white teeth. He looked at Ye Zichen and said, "But I admire your guts. You still dared to come to the fourth floor even though you knew I wanted to kill you."

"The peerless ruler of the Wu Clan wanted to kill me, but I killed him in the end. Lionfire wanted to kill me, but I killed him in the end. You are no exception." The corner of Ye Chenfeng's mouth raised slightly, as he slowly said while ignoring Sen Lei's vicious gaze.

"Hahaha, Ye Chenfeng, I admit that you are much stronger than I imagined, but I will still kill you as if you were a chicken." Sen Lei seemed to have heard the funniest joke in the world as he laughed loudly and said arrogantly.

"Sen Lei, do you think there's any point in arguing like this? Only the weak will brag about their strength of speech. " Ye Chenfeng sneered, and said in a tit for a tat manner.

"Ye Chenfeng, I don't care about your status or background. At the most, I'll turn you into a corpse in three days." A thick killing intent flashed in Sen Lei's eyes and a powerful killing intent radiated from his body.

"There's no need for three days. Two days later, I will challenge you. Do you dare to accept my challenge?" Ye Chenfeng sneered, and said without backing down, while ignoring the aura of death released by Sen Lei.

"Alright, alright, I'll definitely kill you in two days." Sen Lei looked at Ye Chenfeng with a sinister gaze. His terrifying gaze caused people to shudder.

Looking at the two of them fighting each other, the atmosphere in the trading center became even more tense than before. The noisy trading area just now had become completely silent.

Right at this moment, the manager of the Treasure Pavilion, the white clothed man, walked in and mediated, "Alright, both of you, calm down. This is not the place to settle our grudges. Let's conduct our private transactions."

"May I know which one of you is willing to make the first move and start the trade?"

"I'll go first." Ye Zichen drank a mouthful of tea from the beautiful maid, then slowly said, "I have two demon heart crystals that contain a great amount of magic that can refine the body and increase the soul power. One of them wants to exchange for a pill with the ability to refine marrow, the other wants to exchange for Heavenly Soul Grass, or a kilogram of 10,000 Year Spirit Milk."

"En!"

The Limitless Thunder came from the seventh grade Holy Land, the Dark Asura Hall. The soul technique he cultivated was similar to a demonic art, so when he saw the Demon Heart Crystal in Ye Zichen's hand and felt the energy it contained, his eyes immediately lit up.

If he could obtain two Demon Heart Crystals from Ye Chenfeng, he believed that he would definitely be able to improve his strength and reach the peak of the first level of the Inverted Beast King.

Many people in the trading center were also very interested in the demon heart crystal in Ye Chenfeng's hand. However, they did not have anything that Ye Chenfeng needed, so no one offered a price for a while.

"Ye Chenfeng, do you dare to make a deal with me?" The corners of Sen Lei's mouth curled up slightly, revealing a thought-provoking smile as he deliberately asked.

"As long as you can take out what I need, I will naturally make a deal with you." Ye Chenfeng said without changing his expression.

Since he dared to take out the Demon Heart Crystal, he naturally wasn't afraid of Forest Thunder taking it away.

"I have a Jade Marrow Stone that can temper one's marrow. How about a heavy bottle of 10,000 Year Spirit Milk for two Demon Heart Crystals?" Sen Lei took out a blood-red Jade Marrow Stone that seemed to be flowing with blood from his Universe Ring and a heavy white jade bottle as he spoke.

"The effect of this Jade Marrow Stone is inferior to pills and requires 1000 high grade soul crystals. As for the 10,000 Year Spirit Milk, you only need to have enough weight and quality."

Ye Chenfeng had heard of the Jade Marrow Stone before, so he knew that its value was very high. The effects of Tempering Marrow were also very obvious, but he intentionally blackmailed Sen Lei as he coldly said that.

"Ok, deal!"

Sen Lei did not even think twice before agreeing.

The reason he was so happy was that the true effect of the stone milk was to refine pills, which was limited to raising his strength. As long as Ye Chenfeng did not break through within two days, he was completely confident that he could kill Ye Chenfeng. As long as he could kill Ye Chenfeng, everything on Ye Chenfeng would be his.

"Sen Lei, the demon heart crystal contains an extraordinary amount of demonic energy. When refining it, you can't be corroded to death by the demonic energy!"

Ye Zichen completed the transaction with Sen Lei and checked the Jade Marrow Stone and the Myriad Spirit Milk. After confirming that there was no difference, he purposely spoke up.

"Hahaha, Ye Chenfeng, you should still care about your life." Sen Lei laughed loudly before arrogantly saying, "You only have two days left to live. You better cherish the rest of your life."

After saying that, Sen Lei, who was in a good mood, got up and left. He couldn't wait to go back and refine the two Demon Heart Crystals.

"Sen Lei, do you really think you've gotten lucky? I'll immediately let you know what sort of foolishness you have when you trade with me." As he gazed at Sen Lei's proud and aloof back, the corner of Ye Zichen's mouth raised slightly, revealing an ice-cold smile.

After Sen Lei left, the atmosphere of the entire private trading fair became much more relaxed. Many people took out their rare items to trade.

Ye Zichen did the same thing in succession, using two top grade Earth grade equipment, the fire mantis' beast core and forelimbs, to exchange ten batches of materials to refine the Shadowshape Golden Needle Talisman, and other than Yun Zhi Ma, the rest were used to refine the Three Apertures Heaven Pellet.

After harvesting what he needed, Ye Chenfeng did not stay for long. He tactfully refused the beauty that the man in white had arranged for him to sleep. He left the trade center and returned to his rented high-grade training room to cultivate in seclusion.

Preparing for his duel with Sen Lei in two days' time.
