“You don’t know a good person’s heart.” Ye Feng snorted coldly and said no more, just secretly on guard.



A Qingyun Sect disciple beside Zhao Dezhu could not wait to open a jade bottle, and a strong fragrance of elixir suddenly filled the air.



"Yes...it's Xuanyuan Dan! And it's the best Xuanyuan Dan!" The disciple shouted in surprise. Xuanyuan Dan is a top-quality elixir cultivated by monks in the Golden Dan stage, and one piece is worth a lot of money.



Others were even more excited when they heard this, and started to snatch the jade boxes and vases one after another.



Zhao Dezhu also picked up a jade box and was about to open it. Suddenly, something happened!



The lids of those originally quiet alchemy furnaces suddenly popped open, and jets of black smoke spewed out from them, filling the entire stone chamber in an instant!



"Ah——!"



"Toxic!"



Screams rang out one after another, and the Qingyun Sect disciples who had inhaled the black mist had black energy quickly appear on their faces, their bodies twitched and fell to the ground, foaming at the mouth, and their breath quickly weakened.



Even Zhao Dezhu, who was on the seventh level of the golden elixir, changed his expression drastically. He quickly held his breath and mobilized his spiritual power to resist, but he still felt dizzy and his limbs were weak.



"It's...it's the ten thousand-year corpse miasma!" Zhao Dezhu shouted in horror, "What's being refined in these alchemy furnaces is not elixir at all, but corpse poison!"



"Quickly retreat!" Ye Feng's expression changed and he immediately pulled the Tianji Sect disciple beside him to retreat.



Fortunately, they listened to Ye Feng's words and did not rush forward. They were far away from the alchemy furnace at this moment and did not inhale much black mist.



"Ye Feng! Save me! Save me!" Zhao Dezhu crawled toward Ye Feng in panic, his eyes full of fear and regret. He finally understood now that Ye Feng's reminder was not alarmist.



Ye Feng has no sympathy for such smart people who want to bite back.



"Do you know how to call for help now? It's too late!"



The pitch-black corpse miasma spread very quickly and caught up with Zhao Dezhu in the blink of an eye.



"No——!" Zhao Dezhu let out a desperate scream, his body was swallowed by the black mist, and he soon became silent.



In the blink of an eye, seven or eight Qingyun Sect disciples, including Zhao Dezhu, died in the alchemy room, turning into black corpses exuding a foul odor.



"It's... so dangerous!" A Tianji Sect disciple said with lingering fear, cold sweat dripping from his forehead. If Ye Feng hadn't reminded them in time, they might have ended up like the people from Qingyun Sect.



"Senior Brother Ye, you are really good at predicting things!" Another disciple looked at Ye Feng with admiration.



Ye Feng shook his head: "I'm just being cautious. This fairy palace is full of weirdness, we must be more careful."



He glanced at the stinky corpses and the corpse miasma that was still spreading, and said solemnly: "It is not suitable to stay here for a long time, let's go!"



Everyone nodded quickly and followed Ye Feng to quickly leave the alchemy room full of death.



After passing through the alchemy room, there are several forked roads ahead.



Ye Feng did not hesitate this time. Based on his intuition, he chose the most common-looking fork in the road and walked in.



This branch road is narrower than the previous passage, and the slope is downward. It seems to lead to the lower level of the palace.



After walking about a hundred feet, a stone gate appeared in front of them. The stone door is closed, with some ancient runes carved on it.



"What could be inside this?" a disciple asked curiously.



Ye Feng stepped forward and carefully observed the runes on the stone door, and found that these runes seemed to form a small sealing formation.



"This formation is not strong, it should be able to break through." Ye Feng said, and then activated the power of the stars in his body, condensed it on his fingertips, and quickly carved on the stone door.



A moment later, as Ye Feng made his last stroke, the runes on the stone door flashed and then dimmed.



"Creak——"



The stone door slowly opened inward, revealing the scene inside.



Behind the stone gate is a secret room about ten feet square. In the center of the secret room, there was a stone platform, and lying quietly on the stone platform was a long sword with a simple shape.



The whole body of the long sword is green-black, and there is a faint flash of light on the sword body, exuding a vicissitudes of sword intent.



"It's... it's a Taoist weapon!" A disciple exclaimed.



"What a powerful sword! This is at least a low-grade Taoist weapon!"



The eyes of several Tianji Sect disciples showed fiery colors.



Ye Feng's eyes also lit up. He could feel that this ancient sword contained extremely powerful power, which seemed to be a bit stronger than the Star Thunder Sword in his hand.



After all, the Star Thunder Sword is a top-notch divine weapon, and above the divine weapon is a Taoist weapon.



"I'll get it!" A disciple of the Tianji Sect who was closest couldn't hold himself back and was about to step forward.



"Wait!" Ye Feng stopped him again, but his eyes fell on the ground below the stone platform.



The ground there was carved with a circle of fine bloody lines, forming a strange pattern and exuding a faint smell of blood.



"This is... the blood sacrifice formation?" Ye Feng frowned.



He had seen records about this formation in the sect's books. The blood sacrifice formation is an extremely evil formation, usually used to warm evil weapons or perform some kind of sacrifice.



"Senior Brother Ye, what's wrong?" the disciple asked in confusion.



"There is something wrong with this sword." Ye Feng said solemnly, "There is a blood sacrifice formation under the stone platform. I'm afraid this sword is not a good thing."



"Huh?" Several disciples were shocked when they heard this, and the heat on their faces immediately subsided a lot.



"Then...should we take it?"



Ye Feng pondered for a moment and said, "Let's take a look first and then talk."



He cautiously approached the stone platform, and with his spiritual consciousness, he carefully felt the breath of the ancient sword.



The ancient sword does contain powerful power, but in the depth of this power, Ye Feng also felt a faint trace of resentment and hostility.



"It seems that this sword has drank a lot of blood, and may have even swallowed the monk's soul." Ye Feng thought to himself.



Just when he was hesitating to take off the sword, the mutation happened again!



The blood-colored lines under the stone platform suddenly lit up, and a strong blood evil energy spurted out from the formation, instantly covering the entire secret room!



At the same time, the ancient sword on the stone platform also made a piercing sword cry, the sword body trembled violently, and a violent and bloodthirsty sword intent rose into the sky!



"No! The formation has been touched!" Ye Feng's expression changed.



He did not expect that this blood sacrifice formation would be so sensitive. He just observed it closely and activated it on its own.



The violent sword intent turned into countless fine sword auras, shooting towards Ye Feng and others like a heavy rain!



"Be careful!" Ye Feng shouted, and the Star Thunder Sword instantly unsheathed, dancing out a curtain of star light swords, protecting several junior disciples behind him.



"Ding-ding-dang-dang--!"



A dense collision sounded, and the bloody sword energy hit the starlight sword curtain and was shattered one after another.



But the ancient sword seemed to be completely activated. The blood on the sword was shining brightly, and a more condensed and terrifying blood-colored sword sword struck Ye Feng head-on with a tyrannical momentum!



"Senior Brother Ye!" Several Tianji Sect disciples turned pale in horror.



Ye Feng's eyes condensed, and the original power of the dragon soul and the power of the stars in his body exploded at the same time!



"Star Slash!"



He roared, and the starlight on the Star Thunder Sword surged. A concentrated star sword energy, like a meteor piercing the night sky, bravely faced the bloody sword!



"Boom!"



Two completely different but equally powerful sword energies collided in mid-air!
