As night fell, a waning moon hung high in the sky.

In the mountains and forests, the moonlight is sprinkled, rendering the endless land into a silver world, and occasionally an unknown fierce beast roars far and near, adding a lot of gloom to the land at night.

Meng Nan lay on a flat rock, holding his hands behind his head, looking up at the night sky with only the moon and no stars, and his thoughts drifted somewhere.

After a long time, he sat up, looked back at a cave not far behind him, the flickering light of the fire was shining through, and some soft whispers could be faintly heard, he shook his head, and lay down again.

He didn't really fall asleep, but let out his senses, enveloping a large area nearby.

That's right, Meng Nan was keeping vigil.

For the past three days, he has been undertaking the work of vigil.

There's no way, who let the four delicate girls go with him, can't he run to rest with a big man and let the four beauties help him guard it, right?

Besides, the vigil is a trivial matter, and the most important thing is that Meng Nan needs Su Qing to fall asleep before he can do it.

That's the transmission of power in a dream!

In the past three days, every night, Meng Nan would wait for Su Qing to fall asleep, and then use the Dream Returning Mind Method to take her into a dream and impart some knowledge about Dan Dao.

This is a benefit that all students in Mengnan can enjoy!

Having said that, since Su Qing gave up the Red Sun Demon Flame and switched to the ordinary flame formed by Yuan Force to alchemy, perhaps because of her accumulation, her alchemy level has improved by leaps and bounds in just three days, reaching the level of a high-level Dan master at a jaw-dropping speed, and even Meng Nan, who has been teaching her in secret, was taken aback.

Such a talent is amazing.

Among all Meng Nan's students, perhaps only Tang Seventeen's talent in the formation path could be compared.

Due to the constraints of the environment, Meng Nan was destined not to be able to follow Su Qing for a long time to guide her, not to mention, after leaving the Wansha True Domain, he didn't know when he would meet again, so he planned to use the Dream Returning Mind Method in the shortest possible time to teach Su Qing the knowledge of the Grandmaster-level Dan Dao that he possessed.

Of course, even if Su Qing's talent is against the sky, it is impossible to master all the things taught by Meng Nan in a short period of time, but the seeds are planted, and when she grows up in the future, comprehension will come naturally.

As the night deepened, the fire finally went out in the cave where the four women were resting.

It didn't take long for Meng Nan to hear their even breathing after they had fallen asleep.

He sat up again, crossed his legs, his powerful and incomparable divine sense moved at will, and the pure Haoran righteousness came out of his body, and in an instant, an illusory dream sneaked into the cave and landed on the sleeping Su Qing.

Nothing was said all night.

In the early morning of the next day, when Dongfang had just turned the white of the fish's belly, Meng Nan opened his eyes, exhaled a heavy breath of turbidity, and then rose from the top of the mountain rock.

He glanced back at the cave behind him, and a faint warmth welled up in his eyes.

"It's time to leave. Meng Nan said secretly, "After a delay of three days, everything that should be taught to Su Yatou has already been taught, and the teacher led her into the door, and her cultivation still depends on herself." ”

Su Qing's talent is not bad, and her background is also amazing, among all the students he has taught, the conditions should be the best, and now after her own guidance, Meng Nan believes that she will soon rise to fame and soar to the sky!

Next, it's time to get your own business done.

"The Earth Evil Qi is still short of the Thunder System to be consummated, we must find it as soon as possible, improve the cultivation, and the Thunder Emperor's Secret ......"

Thinking of the Thunder Emperor's Vault, Meng Nan's eyes flickered, revealing a strange expression.

Two days ago, Meng Nan and the four girls arrived in the Inner Domain.

After entering the central area of this Ten Thousand Evil True Domain, the number of martial artists they encountered gradually increased, and many of them were amazing after seeing the four women, and they took the opportunity to talk, and from the mouths of those martial artists, Meng Nanda heard a lot of news.

One of the most amazing is the location of the Thunder Emperor's Vault, which has been found!

When he first heard the news, Meng Nan was taken aback.

The reason why he entered the Ten Thousand Evil True Domain, the biggest purpose was the Blood Dragon Grass hidden in the Thunder Emperor's Secret Vault, if the Secret Treasure was amputated by someone, then wouldn't he want the bamboo basket to be empty?

However, Meng Nan quickly put his mind at ease.

Because as far as he knew, those who discovered the Thunder Emperor's Vault could only stare at the outside of the Vault, and there was no way to open the Vault Door at all.

Combined with the news inquired, Meng Nan checked the treasure map in his mind and determined the location of the Thunder Emperor's secret cache, if it wasn't for the need to stay by Su Qing's side for the past two days to pass on the art, he would have rushed over there a long time ago.

Now Su Qing's study can come to an end temporarily, and he can also free up his hands to do his own thing.

He didn't wait for Su Qing to wake up, but took out a purple bamboo cane and carved a line of words on the mountain stone, and then unfolded his body and floated away.

Not long after Meng Nan left, the four girls who had rested in the cave all night also woke up, and they stretched their waists and walked out of the cave with a refreshed expression.

Su Qing walked last, her expression full of shock. 、

"It turns out that the teacher's Dan Dao attainments have reached the grandmaster level!"

At this time, she was still completely immersed in the dream of last night, and her heart swelled with turbulent waves.

Master!

Even if you look at the four seas, there are only a handful of grandmaster-level Dan masters!

And she actually met one and became his student!

What a great opportunity!

Su Qing felt that she was simply favored by the goddess of luck, otherwise, it would be a blessing that she had cultivated for several lifetimes to make her a student of Teacher Meng?

In the past three days, Su Qing has felt the magic of Teacher Meng.

She had never heard of someone being able to teach her all kinds of skills in a dream.

A dream come true!

This is definitely a means that only gods can have, but she has experienced it in her own teacher.

Others may not be able to see it, but Su Qing knows that in just three days, under the teaching of Teacher Meng, her Dan Dao level has been reborn and improved by leaps and bounds!

God-like Teacher Meng!

At this time, Su Qing admired Teacher Meng so much in her heart.

"Huh, where's Meng Nan?"

While thinking about it, Su Qing suddenly heard Ji Mei'er's puzzled voice.

Su Qing chuckled in her heart, and she didn't know why, but she suddenly had an ominous premonition, as if the most important thing in her life was leaving her.

At this moment, not far away, Qiu Ling suddenly shouted, "Little Sister Su, come and take a look!"

Su Qing took a deep breath, flashed up on the flat mountain rock, and saw a line of big characters carved on the mountain stone.

"Girl, you have to fight for your anger, you are gone for the teacher, and you will see you again!"

"The teacher is gone?"

Su Qing's face changed suddenly, her body shook suddenly, and she felt a blur in front of her, and tears couldn't stop falling like pearls with broken threads.

"Meng Nan actually left like this?"

Ji Mei'er looked at the dashing line of big characters left by Meng Nan, and she didn't know why, her heart suddenly emptied, and she was stunned.

She stretched out her lotus arm, took Su Qing into her arms, patted her shoulder gently, and said, "Look at the traces of these words, Meng Nan should leave not long ago, or should we chase after her?"

Su Qing choked, took a deep breath, bit her lower lip lightly, and said, "No, the teacher must have something urgent to say goodbye...... Oh, the teacher is right, the coming day is long, we will definitely see each other in the future, and when the time comes, I will definitely surprise the teacher. ”

She paused, stretched out her hand to wipe the tears from her eyes, and said, "Sister Mei'er, after this trip, I am ready to start retreat, and I must become a Dan Dao master within a year!"

"What?" Ji Mei'er gasped, "Becoming a Dan Dao master within a year, is this ...... Is it possible?"

"Hehe, only in this way will I live up to the teacher's teachings!"

Su Qing said, her delicate voice was categorical and full of firmness.

"Teacher's teachings?"

Ji Mei'er's eyes showed a somewhat strange look.

In the past three days, she hadn't seen Meng Nan teach Su Qing anything.

Su Qing glanced at Ji Mei'er and did not explain.

Just like Teacher Meng said, passing on gong in dreams is the ultimate secret that only people in their field can know!

She turned her face and looked at the rolling mountains and forests, and her eyes welled up with incomparable firmness, "Teacher, don't worry, the girl will definitely fight!"

......

Ji Mei'er looked at the dashing line of big characters left by Meng Nan, and she didn't know why, her heart suddenly emptied, and she was stunned.

She stretched out her lotus arm, took Su Qing into her arms, patted her shoulder gently, and said, "Look at the traces of these words, Meng Nan should leave not long ago, or should we chase after her?"
