There were nine passages in the hall of Black Stone Castle. Li Feng walked towards the passage on the far left as the captain said. The moment he walked into the passage, a dazzling red light suddenly appeared at the entrance of the passage.

"This..." Li Feng looked at all this in surprise. After a moment, the red light gradually faded and all the secret patterns dimmed.

Li Feng calmed down his mood and walked into the passage. The entire passage was diagonally downward and led to the ground. The passage was nearly six meters wide and four meters high, very square, and there were ancient reliefs on the walls.

On the ground, it is made of some white jade.

"This is too luxurious!" Li Feng sighed in his heart.

After a while, Li Feng arrived at the end of the passage.

When Li Feng walked out of the passage, he found that at the end of the passage was a wide hall. There were also many black-armored men in the hall.

"The food is coming!" Li Feng said to the black-armored men.

"Are you new?" One of the black-armored men walked towards Li Feng. Although Li Feng was a new face, the black-armored men were not worried. When Li Feng just walked into the passage, the secret patterns lit up in the passage could detect the human cultivation, which served as a warning for the people guarding inside. They already knew that Li Feng's cultivation was only at the peak of the eight-star warrior, and these black-armored men would not care about a person who had not even reached the level of a martial artist.

"Yes!" Li Feng nodded and put down the food box in his hand.

The black-armored man opened the food box and carefully checked the food inside, then he said to the other guards in the hall with confidence: "Brothers, it's time to eat!"

There were twelve men in black armor in the hall. They gathered together and began to eat voraciously. However, a smile appeared on the corner of Li Feng's mouth. He saw a bottle in his storage ring in his arms, and then quietly opened the bottle.

A faint white mist emerged from the bottle and quickly dissipated in the air.

Those black-armored men who were taking a lot of fun all fell to the ground. This is a very special kind of drug called "Looking back and not ecstasy"! It is one of the best prescriptions left by Li Jingqiong back then. However, if you want to prepare such a medicine, you must cultivate the mysterious energy. Moreover, the medicinal materials required for this prescription are very precious. Even Li Feng has only collected a little bit over the years.

"Hehe, it's so useful! You have to make more in the future!" Li Feng smiled in his heart, then walked towards a door with a fire in the hall.

When Li Feng walked into the passage, the mysterious energy in his body was suddenly suppressed by an invisible force.

"How could this happen?" Li Feng frowned. He felt this strange feeling once in Tianlang Valley, but he didn't expect that he could feel it again. Inside the cave door was an alchemy room, with a huge alchemy furnace in the center. An alchemist was busy throwing the same medicinal materials into the alchemy furnace. Li Feng found that the black-lined desire root was placed in a hundred jade tray. On a tray next to the black-lined desire root, there was a crystal cup. In that cup, there was a small pinch of purple rice grains, and the rice grains emitted a brilliant light, which was very eye-catching.

"That's Tianshan purple bamboo rice! Nangong Yue'er really got this thing! But where is the Taiyi Jin Jing?" Li Feng's eyes glanced through the entire alchemy room several times, but he didn't notice it.

"Who asked you to come in, get out immediately!" The alchemist suddenly stopped moving and shouted at Li Feng. Generally, alchemists will not let outsiders watch when refining alchemists. This is a regulation in the alchemist industry.

"Bang!" Li Feng flashed, came to the alchemist, and slapped it directly in the face of the alchemist, and pulled him away. An alchemist was no match for Li Feng in this alchemist that suppressed the mysterious energy.

"You!" The alchemist was slapped by Li Feng.

Li Feng stepped on his face and leaned over to ask the alchemist, "If you don't want to die, tell me honestly where the Taiyi Jin Jing is?"

"Taiyi Jin Jing? I don't know!" The alchemist immediately shook his head.

Li Feng punched him in the stomach and said coldly: "I know Nangong Yue'er is asking you to help her refine Taiyi Spirit Pills. There will definitely be Taiyi Jin Jing! If you don't want to die, be honest!"

"I really don't know this hero. It takes a long time to refine Taiyi Jin Jing. Only in the final critical step can you add Taiyi Jin Jing. Now Nangong Yue'er hasn't given me the Taiyi Jin Jing yet!" the alchemist said crying.

"Crack" Li Feng cut off the alchemist's neck. A fourth-grade peak alchemist died in Li Feng's hands. He took his lower body, took off the storage ring on the alchemist's body, and then scraped away all the things in the alchemist's room.

Li Feng quickly evacuated, but when he was about to walk out of the gate of Black Stone Fort, Nangong Yueer hurried in with a large group of people, just blocking him.

"What a Li Feng, I almost came to your words!" Nangong Yue'er looked at Li Feng and said indifferently.

"Nangong Yue'er!" Li Feng secretly cried in his heart and quickly retreated to the center of the hall. He didn't understand how Nangong Yue'er discovered his identity?

"Hmph, it's not bad, it's very disguised!" Nangong Yue'er looked at Li Feng with a sneer and said, "You should be very surprised. How did I find you?"

At this moment, Li Feng had already confirmed that Nangong Yue'er had known his identity, so he returned to his original voice and said, "I am indeed very curious!"

"Haha!" Nangong Yue'er sneered and said, "All this is because of the Tianyuan Qi Practice. You use the Tianyuan Qi Practice to tamper with the black-lined desire refining root. Your technique has changed a lot, and I almost couldn't recognize it!"

Li Feng was shocked. He knew that he was a secret. He forgot that Nangong Yue'er was the culprit who pulled Taiyi Jin Jing from Erya's body. She must have the Tianyuan Qi Practice. Because of this Tianyuan Qi Practice, only he and his grandfather Li Jingqiong, and Nangong Jueyi knew about it. Therefore, with this Tianyuan Qi Practice, Nangong Yue'er could guess his identity.

"Li Feng, if you don't go in heaven, if you don't have a way, if you don't have a way, you will come naturally. It seems that you are despised by your longevity!" Zhang Cuicui looked at Li Feng gritted her teeth, and she still remembered the scene when Li Feng was slapped her face in Tianxiang Tower, Yudan City.

"Hmph, it seems that you little bitch's mouth is not sucked enough!" Li Feng looked at Zhang Cuicui coldly. He knew that this maid was as vicious as her master.

"Li Feng, if you are tactful, you will surrender quickly. In that case, for my grandfather's sake, I will spare you a life!" Nangong Yue'er looked at Li Feng with a cold expression. At this moment, she and those people were more than ten meters away from Li Feng, but no one dared to act rashly.

"Nangong Yue'er, you'd better put away your hypocritical face. Will you spare me? This is a big joke!" Li Feng looked at Nangong Yue'er disdainfully, "I really didn't expect that your heart would be so cruel. It seems that the most toxic woman's heart is. Before you become a woman, your heart is so cruel, and that will be even more amazing in the future!"

Nangong Yueer suddenly became furious. She glared at Li Feng and cursed: "Li Feng, you must understand your own situation now. I will give you another chance to hand over the things and then destroy your martial arts. I will never break my promise and will definitely let you go!"

"Hahahaha..." Li Feng suddenly laughed wildly: "Your martial arts are ruined? Nangong Yue'er, do you really treat me as a fool? If you weren't worried that the materials that refined Taiyi Spirit Pills would be destroyed by me, I'm afraid you wouldn't stand here so politely at this time, right?"

Nangong Yueer was immediately angry. Li Feng's words hit her vital point. Her plump breasts became violently fluctuated because of their anger.

"Li Feng, don't think I dare not attack you!" The cold murderous intent spread across Nangong Yue'er's body.

"Is that so? If you have the ability, come and kill me!" After Li Feng said that, he looked at the entrances of the nine passages behind him. Among them, he had never entered eight passages. However, he knew that there must be a large number of treasures behind these passages, and he rushed into the third passage quickly.

"Looking for death!" Nangong Yueer immediately took action, and two thin needles shot towards Li Feng. Li Feng felt the sound of breaking through the air behind him. The magic of the gods and demons immediately activated, and his body dodged to the right. The two thin needles penetrated his robe, hit the stone wall, and splashed two sparks.

When he saw the two fine needles, Li Feng narrowed his eyes and then said angrily to Nangong Yue'er: "So that day, you were the one who plotted against me at the door of Tianxiang Tower!"

"Hmph, so what if it's me? I'll ask you the last question, or not?" Nangong Yue'er looked at Li Feng coldly.

"Bah, don't even think about it!" Li Feng said, and punched two fists at Nangong Yue'er, and then his figure swept towards a passage on the far right, because he found that Nangong Yue'er's eyes were always aiming there.

"Stop!" Seeing Li Feng rushing towards the ninth passage, Nangong Yue'er's face suddenly changed. She raised her hand and sprinkled more than a dozen fine needles, but none of them hit Li Feng.

"Huh!" Li Feng's figure rushed into the rightmost passage.

"Catch him!" The captain of the guard gave the order and was about to rush into the passage with his brothers behind him to make meritorious service. Just now, it was because of his negligence that Li Feng was infiltrated into the Black Stone Castle.

"Stop it all!" Nangong Yue'er stretched out her hand and stopped everyone.

"Miss, why don't you catch him?" The guards were puzzled.

Nangong Yue'er looked at the rightmost passage and said coldly: "No need, the ninth passage is very mysterious. For thousands of years, our Nangong family has hundreds of people entering, but no one has ever been able to come out alive. This is a road of no return!"

"No way back!" Everyone was stunned. This was the first time they heard this news.
