It is very likely that some of the instructors were nominally talking about the medicine talisman system, and ended up telling a whole day of anecdotes. (Baidu search update is the fastest and most stable)

It is precisely because of the extreme instability of the nameless elder that very few disciples are willing to listen to such a teacher's lectures. At this time, hearing that there was only such a course, Shen Qian was a little hesitant.

"Chu Chen, what do you think, should we sign up for this mentor?"

"For me, it's pretty much the same for any mentor. Chu Chen smiled slightly, in fact, as far as he was concerned, as long as he was given enough time to look through the books in the Great Hall of Books, it really didn't make a difference whether he had a tutor to teach him or not, he just had to rely on self-study.

Seeing Chu Chen's confident appearance, Shen Qian had nothing to worry about, and smiled at the female teacher: "Since that's the case, then let's sign up for this." ”

For the little fairy Shen Qian, as long as someone teaches her.

No matter how unreliable the tutor is, since he has the name of the medicine talisman system, no matter how exaggerated he is, he will always teach something, anyway, he can learn a little bit at this point.

The female teacher nodded, recorded the information of Chu Chen and the two in her hand, and then took out two crystal clear jade talismans and handed them to the two: "The place where this nameless elder teaches is in the Medicine Palace Forest behind the Medicine Palace, and you can only walk in with this jade talisman, don't lose it, go early tomorrow morning." ”

"Got it. The two bowed to the instructor and left the teaching office.

Early the next morning, Chu Chen and Shen Qian came to the front of the entrance of the Medicine Palace Forest.

The Medicine Palace Forest is a forest behind the Medicine Palace, and it is also the only oasis in the entire Ding City.

It's just that the more amazing thing is that you can't enter this forest from the outside world, because from the outside, it seems that the back of the Medicine Palace is the urban area of Dingcheng, and there is no forest!

Therefore, in fact, this forest can be called a secret realm inside the Medicine Palace, and Chu Chen and Shen Qian walked straight to the back of the Medicine Palace with the medicine talisman.

Behind the entire Medicine Palace, there is a cliff that is not very high, and on the cliff is a mottled stone bridge.

This small bridge looks very, very old, and there are traces of wind and rain everywhere, and the palm-sized stone chips are uneven, telling the story of the antiquity of this stone bridge.

This stone bridge is very long, about 500 zhang long. Below the stone bridge is an endless bottomless abyss, which is the "secret abyss" known throughout Dingcheng, and it is said that in the deepest part of the secret abyss lives the town palace guardian spirit beast of the medicine palace, but it has not appeared for hundreds of years.

After walking across the stone bridge and the secret abyss, there is a somewhat low cave.

As soon as I entered the cave, a strong smell of elixir came to my nose.

The light in the cave was a little dim, which made Shen Qian subconsciously move closer to Chu Chen: "What the hell is this place, it's gloomy." ”

In any case, girls will always have an inexplicable feeling of fear in this kind of place.

"I'm afraid this is the legendary elixir cave, it is said that this entire cave is carved from the roots of some extremely thousand-year-old medicine trees, and if you walk through it, you can be baptized by the medicinal qi, making it easier for the pharmacist to perceive the changes in the refining of the medicine talisman. This medicine cave is the treasure of the medicine palace. ”

Chu Chen smiled slightly, "Let you usually read more books, and you don't even know such an important place." ”

"Nerds have nothing to brag about. Shen Qian gave him a blank look.

In fact, the magical legend of the medicine cave does make sense.

After walking through a cave that was about a hundred zhang long, Chu Chen obviously felt that some of his understanding of the way of alchemy had become more profound, and even Shen Qian, who had never been very good at alchemy, clearly felt his progress.

This scene made both of them very happy.

After walking through the medicine cave, Chu Chen and Shen Qian both froze, and there was an open space in front of them. In the clearing, there were two old men with white hair, one on the left and one on the right, sitting motionless on the futon. Beneath them was a flat blue-gray rock with one mysterious formation pattern after another.

The two-instrument dust array!

Chu Chen's surprise was not trivial!

The direction in which these two old men sit is very mysterious, and it is in line with the avenue of heaven and earth of yin and yang. He had seen this kind of formation once, that is, when he was traveling in the Ancient Immortal Mountain, he had seen this special ancient pattern near the top of the mountain.

The Liangyi Dust Array was one of the most famous formations in the ancient mythological era, and its fierce reputation was no less than that of the Jiuqu Yellow River Formation and the Ten Killing Formations.

This is a space-like formation, and it is claimed to be able to load the sun, moon and stars with a particle of dust on the occasion of Dacheng, and it is the mountain protection divine array of the ancient Shu Mountain Sword Immortal.

At this moment, although the lines under the seats of these two old men were not as ancient, vast and vast as Chu Chen had seen at the beginning. But it really has the special charm of the Liangyi Dust Array, which makes Chu Chen a little awe-inspired.

No wonder this forest secret realm is so magical and mysterious, outsiders often only hear its name, but not many people have actually seen it. It turns out that there is such an ancient formation in charge!

"In the secret realm of the forest, idlers are not allowed to trespass. Two little dolls, this is not the place to talk about love. ”

As if sensing the approach of the two, one of the black-robed old men's eyes opened and closed slightly, revealing a dazzling light, "If you don't receive the jade talisman, go back quickly." ”

"Pick up the jade talisman, is this it?" Shen Qian took out the jade talisman given to them by the female mentor from the storage ring and handed it to the two of them.

"Oh, I didn't expect this old man's class to be really attended. The black-robed old man's eyes narrowed slightly, and he nodded, "Go in." ”

"Thank you, two seniors. Shen Qian and Chu Chen saluted the two old men, and hurriedly walked towards the forest at the edge of the clearing.

When they really stepped into the scope of the Medicine Palace Forest, the two of them found that this forest was really big beyond imagination.

In front of me, there is an endless field of dark green trees. And the amazing thing is that the giant trees in this forest are not like ordinary primeval forests, only the leaves are green, but the trunks are blue-gray.

All the numbers in this forest are dark green from top to bottom, and it looks like a huge piece of dark green jadeite carved from it, and it is full of texture.

"Uh...... How's that going now?"

Shen Qian was very surprised, the forest in front of her was too big, like an endless sea of green, and the trees in it seemed to be the same species, once you fell into it, it was like falling into an endless green space, and you couldn't tell the direction at all.

"Liangyi Dust Array, the power of dust derives into the world, the range is endless, this level will test our understanding, use your heart to sense the entire space, you can always find the exit. ”

Chu Chen smiled slightly, closed his eyes slightly, and his spiritual sense slowly spread around.

Shen Qian also slowly closed her eyes when she heard this, her current cultivation had also reached the peak of the Lingquan realm's "Human Spring First Order", and her own qualifications, roots, and talents were not bad.

Therefore, as long as you calm down, you will soon sense a trace of special aura in the void.

If you use your spiritual sense to probe carefully, you will be able to find that there are countless fine "spiritual power lines" in the seemingly calm forest void.

These lines of spiritual power emanated from each tree, extending into the distance in a unified direction, as if they were forming a "passage".

"This is ......" Shen Qian was slightly surprised. She had never imagined that she would be able to see such a gorgeous and dazzling scene when she opened her spiritual sense.

"The essence of this forest is a huge ancient formation. Each giant tree is actually a part of the formation, so these spiritual rays are essentially the lines and trajectories of the formation. As long as we follow these tracks, we can always find the heart of this formation, which is where this substitute tutor lives. Chu Chen smiled slightly.

"Hahaha...... I haven't seen you for many days, and Brother Chu's eyesight is still sharp!"

Just as Chu Chen was talking to Shen Qian, a heroic long laugh came. The two of them were stunned for a moment and turned their heads to look, and saw an old man walking out of the woods. He looked to be sixty or seventy years old, with snow-white hair and beard. But what was surprising was that the robe that this person was wearing was actually the clothes worn by the students of the Medicine Palace, not the robes worn by those elderly tutors and elders.

Old students? Such an old freshman?

Shen Qian's eyes widened, Chu Chen only hesitated for a moment before recalling, and smiled at the old man: "Senior Li, it's been a long time." ”

The person who came was Li Taixin, the oldest of Chu Chen's freshmen in the Medicine Palace.

When Chu Chen first entered the Medicine Palace to study, Li Taixin ranked sixth on the "Medicine Palace Alternate Freshman List", because he was a late bloomer, and it was not until he was in his seventies that he discovered his cultivation qualifications and entered the Medicine Palace to study.

I had a relationship with Chu Chen during the freshman trial of the Medicine Palace, so I had a very deep memory of him.

"Hehe, Brother Chu laughed. Those who have attained the path of cultivation come first. In terms of cultivation and qualifications, I am not as good as you, but I am a few years older, how dare I afford the word 'senior'. Just call me by name. ”

Li Taixin laughed, "I didn't expect to meet you here, but I haven't seen you for more than half a year." ”

"Yes, when I entered the Medicine Palace, I realized that the cultivation course was so heavy. Chu Chen smiled and nodded, "Did you also come here to take that unknown mentor's medicine talisman refining course?" "Hey, don't mention it!" As soon as he heard Chu Chen's words, Li Taixin suddenly shook his head with a wry smile, with a helpless expression, "The old man is old, and his body is just not flexible. In order to obtain the qualification to learn the medicinal talisman system zuò, it took too much time and effort to catch three Xuanjing fish. By the time I had finally caught enough of three fish, I was told that all the classes were full. In desperation, I had to come to this nameless mentor. Anyway, when the time comes, I can learn a little bit. What about you?" Chu Chen smiled slightly when he heard this: "This is also the case for us. In that case, let's walk together, so that we can take care of each other. ”
