It was not long before the sky was dark, and the conversation between the master and the apprentice in the stone chamber did not take long. The road of light and darkness in the cave is still accessible, and the Medical Saint is walking in it.

The old man was very happy in the stone chamber because of the progress of his two junior brothers. Now he frowned. This was the world of light. The old man was calculating something while walking, sometimes shaking his head, sometimes stroking his beard, and his mouth moved slightly, not knowing what he was talking about.

The light around suddenly darkened, and it was already a dark world.

"Ancestral Temple, yes, ancestral temple!" The doctor saint suddenly shouted, and the figure disappeared.

...

Time passed quietly like water. Zhang Zhifeng had already memorized hundreds of thick medical books. After his creativity increased, his memory ability was greatly enhanced, and of course, his memory level was much faster.

"Junior brother."

Hearing the voice of his senior brother, Zhang Zhifeng turned his head and saw that the stone door in the corner was opened. Chen Yun stood inside and stretched out half of his body. One hand was making gestures to let him pass, but the other hand was stretching into the valve chamber.

Zhang Zhifeng walked over and said, "What's wrong with Senior Brother."

"Come in, hurry!"

"Didn't the master say I won't go in?"

Chen Yun said anxiously: "That's because the master is afraid that something will happen if you read these books. You can just come in and not read them now. Come on, come on, show it!"

Zhang Zhifeng walked two steps closer and was about to ask in detail, but Chen Yun dragged it in. He saw that there was a book on Chen Yun's other hand. He couldn't help but ask curiously: "Senior Brother, have you found that book about the martial arts that do not move through the meridians?"

Chen Yun shook his head and said excitedly: "No. After my second golden scale grew, I can actually understand some books again. This is my new book!" He said that.

"Oh, what is it?" Zhang Zhifeng reached out to take it. But Chen Yun shrank his hand and dodged.

"You can't see it. If you think of it as flying ashes again, it would be strange if the master is not crazy."

Zhang Zhifeng smiled awkwardly and said, "Senior Brother, tell me what this book is written!"

Chen Yun said happily, "Do you know where our teacher's secret room is?"

Zhang Zhifeng shook his head and asked, "Is this book about the location of this secret room?"

Chen Yun shook his head gently, looking unfathomable.

Zhang Zhifeng was anxious and raised his fist to face each other violently, but Chen Yun spoke softly.

"There are many dense areas around this secret room, just like the valve room where we are now, and the bedroom where we sleep, these are opened through the patterns on the wall of the main room, but in fact, there is a dense area behind each pattern. This book records a dense path!"

"Ah!" Zhang Zhifeng was overjoyed, "Then senior brother, please write it down quickly and let's go and have a look."

"Okay, wait for me to remember, it will not be so easy to find this book next time." Chen Yun sat down on the ground and began to remember it with all his concentration.

Although Chen Yun's memory is not as perverted as his junior brother, there is actually not much information on this volume. Soon, Chen Yun had already come to his senses. He let go of the book in his hand, and the volume fluttered into the book group.

Zhang Zhifeng said excitedly: "Senior brother, have you remembered it?"

"Well, let's go!"

"good!"

The two brothers returned to the main room, and Chen Yun was searching carefully on the surrounding walls. Zhang Zhifeng did not dare to breathe, for fear of disturbing his senior brother.

Chen Yun's eyes lit up and he quickly walked to the bookshelf: "Junior brother, push this away."

"Okay." Zhang Zhifeng hurriedly stepped forward and pushed open the bookshelf.

Chen Yun carefully searched on the carving patterns behind the bookshelf, and his fingers kept fumbled on the patterns on the wall.

"It's here." Chen Yun suddenly spoke excitedly. He muttered something in his mouth, as if he was recalling the book he had just recorded. Finally, he slowly stretched out his hand, and his fingers began to scratch the corner of a beast's head on the pattern. As a strange track on the finger, a trace of purple-gold light penetrated into the pattern. A mysterious pattern on the pattern lit up. Chen Yun quickly stopped and the two brothers were waiting nervously.

The opening of the valve chamber and the bedroom are silent, but this mysterious door is so moving!

The mysterious pattern that emerged was prominent, as if it had left the wall, slowly rotating, a rumbling sound rang out, and a gravitational force gradually strengthened...

"Click!" Everything stopped abruptly, and the walls returned to their original state, as if everything that had just been born was just illusion.

The two brothers opened their mouths in surprise.

"What's wrong?"

"Failed!"

"Senior brother, you didn't use anything wrong just now, right?"

Chen Yun frowned slightly: "No, I'm just doing it as written on that book!"

"Why do you go and read that book again?"

"How can those hundred thousand books be so easy to find?"

Zhang Zhifeng touched his nose and said uncertainly: "Will you try again?"

"Okay, try again!"

Chen Yun stretched out his finger and scratched the pattern again. The same mysterious pattern appeared again, slowly rotating with a rumbling sound, gradually accelerating. The two brothers waited nervously, their hearts pounding, and Zhang Zhifeng felt that his body began to tremble.

Under the nervous gaze of the two, a small dark hole gradually appeared in the pattern that turned into a blur, and the hole gradually grew larger. After a long time, the rotating pattern disappeared, and what appeared in front of the two was a one-person-high door-shaped hole.

Chen Yun looked closely and his strong eyesight made him see that the cave was filled with strange black liquid.

"Junior brother, it seems that there is a strange liquid inside. Go in?"

Zhang Zhifeng looked at it, but compared to his senior brother, he had less powerful eyesight after refining his body with the magic medicine, but he couldn't see clearly. He stared at the hole that seemed to be able to swallow everything, and couldn't help but frown.

At this time, the entrance of the cave slowly began to grow smaller and shrink faster and faster, and in a blink of an eye it was half smaller. Chen Yun said anxiously: "Quick, the cave is about to disappear. If you don't enter, you may have no chance."

Zhang Zhifeng made a fierce decision. If he didn't have this courage, how could he talk about going to make a big 6, and how could he take revenge? "Okay, go in."

"Okay!" Chen Yun rushed in. Zhang Zhifeng thought for a while, picked up the lighting stone on the wooden table, and also brushed the ground into the hole.

The hole is closed and the wall is restored as before.

As soon as he entered the hole, Zhang Zhifeng felt a biting cold and cold. The surroundings were filled with liquid like water. However, the liquid showed a faint pink under the illumination stone in his hand, which was a little beautiful and a little desolate.

Chen Yun was next to Zhang Zhifeng, and both of them were observing and feeling it, and they did not rush to go deeper. Both of them were second-rate masters, so of course they would not be trapped by breathing, let alone Chen Yun was still a royal family in the water.

Similarly, both of them have the arrogance and confidence of masters, and they would not dare to enter this unknown place.

"Go forward slowly, be careful!" Chen Yun said in a voice transmission.

Zhang Zhifeng nodded slightly and moved forward slowly with his senior brother.

The strange liquid rushed through his body. Zhang Zhifeng felt cold all over and was a little stiff from the cold. He couldn't help but speed up the operation of his ingenuity to eliminate discomfort. Sure enough, the place where the ingenuity flowed quickly recovered.
