Afterwards, Xu Sheng, Jiang Lu and Sun Yuanba took the black snake back and cooked it.

That night, Xu Sheng brought the prepared snake soup to Mu Hongling and told her that his true strength was known by Jiang Lu and Sun Yuanba.

"Is that so?"

Mu Hongling asked, "They don't suspect anything, do they?"

"No, they just lamented that their talents were not as good as mine."

Xu Sheng said: "And they said they would keep it a secret for me, not even telling anyone else in Hongling Peak."

"That's good."

Mu Hongling nodded and said, "If we want to refine the purple spirit crystal in the future, we should be more careful!"

Xu Sheng also nodded.

Now more than six hundred years have passed.

Xu Sheng has grown into a teenager of about twelve years old.

Although it still looks a bit immature.

But he is already nearly 1.6 meters tall.

"It's been another hundred years now, right?"

Before Xu Sheng could say anything, Mu Hongling asked again, "Let's practice again tonight. Wait for me in the evening."

"yes."

Xu Sheng was shocked and said, "Disciple obeys your command."

To avoid being discovered by others.

Now Mu Hongling has arranged for them to bathe together in Xu Sheng’s practice room.

If Xu Sheng were allowed to hide in Mu Hongling's residence, he might be discovered.

On the contrary, Mu Hongling could sneak up quietly.

Of course, there haven't been any further breakthroughs for the two over the years.

They just changed a few hugging positions while bathing together, and Xu Sheng was blindfolded the whole time.

He didn't dare to do anything to Mu Hongling.

I was afraid that if I angered her, I wouldn't be able to improve my cultivation faster!

In the blink of an eye, it was night.

There were soft knocking sounds of varying lengths outside the door of Xu Sheng's training room.

Xu Sheng immediately went to open the door and saw Mu Hongling standing outside the door in black.

“Master!”

Xu Sheng said: "Come in quickly."

"Um."

Mu Hongling's pretty face was slightly moist as she leaned forward and walked in.

Afterwards, Xu Sheng naturally closed the door completely and hung a sign outside announcing the retreat.

In this way, fellow disciples and servants will not come to disturb us.

Then Mu Hongling blindfolded Xu Sheng.

Then soon the two of them hugged each other again and sank into the pool water soaked in purple powder.

"Your strength has improved now. Shall we try to increase the potency of the medicine?"

Just as Xu Sheng was refining the medicinal power while feeling Mu Hongling's embrace as usual, Mu Hongling suddenly said.

"Increase the potency of the medicine?"

Xu Sheng said: "Everything is up to the Master."

"Then I'll start."

Mu Hongling waved her hand again, took out a small piece of crystal, broke it into pieces and sprinkled it into the water.

Soon the energy in the water became even more turbulent.

"ah."

After a while, Xu Sheng cried out in pain.

Because the dosage seems to be a bit too much.

"not good."

At this time, Mu Hongling's face also changed.

She discovered that the method of absorbing and refining through the skin could no longer help Xu Sheng.

"Master, what should I do? What should I do? I won't be killed by all this energy, right?"

Xu Sheng panicked and said, "I don't want to die. I haven't even grown up yet!"

Without thinking too much, he tore off the black cloth on his face.

Immediately Xu Sheng saw Mu Hongling in front of him.

Of course, most of her body was submerged in water at this point.

Xu Sheng couldn't see anything either.

Only through the water surface could one vaguely see some outlines, as well as her white neck, collarbone, wet red hair, and delicate face with some water droplets flowing on it.

"Don't worry, there is a way!"

At this time, Mu Hongling did not care about the fact that Xu Sheng had taken off the cloth strip and just said, "Stick out your tongue! Let me suck the blood from the tip of your tongue!"

"What?"

Xu Sheng was stunned for a moment and asked, "Blood on the tip of the tongue?"

But he hasn't reacted yet.

A figure came forward suddenly.

Two white and tender arms had already embraced Xu Sheng's head.

Then Mu Hongling's delicate lips pressed directly onto him.

Then Xu Sheng felt a slight pain on the tip of his tongue.

Then he felt the wound on the tip of his tongue being sucked by something.

Energy is constantly being sucked out of the wound.

Then the boiling and uncomfortable energy in Xu Sheng's body was relieved.

This stalemate lasted for some time.

The effect of the medicine was completely relieved.

Xu Sheng did not suffer from anemia due to the energy supply from the purple spirit crystal.

On the contrary, I feel that the energy I gained after this refining is more than before.

Naturally, I couldn't help but feel happy.

"What did we do?"

Of course, at this time Mu Hongling let go of Xu Sheng and spoke blankly there.

“We just…”

Xu Sheng also stared at Mu Hongling in a daze.

Of course, Xu Sheng didn't wait for anything to happen.

The black cloth magic weapon from before came around like a spirit snake and covered Xu Sheng's eyes.

"We are just practicing, remember that! There is nothing else!"

At the same time, Mu Hongling's voice rang in Xu Sheng's ears: "It's just that the way of cultivation is a little special!"

"yes."

Xu Sheng naturally didn't dare to say anything frivolous.

This wave brings even more benefits!

At this time, anyone who irritates Mu Hongling with words must be out of his mind.

As for the damage to the tip of his tongue, with Xu Sheng's physique, it recovered in a short while.

Anyway, after this day.

Xu Sheng and Mu Hongling's refining methods changed again.

Every hundred years, Mu Hongling would come and bathe with Xu Sheng for more than ten days.

During these ten days, Mu Hongling held Xu Sheng and kept sucking blood from the tip of his tongue.

Of course Xu Sheng did not dare to do anything. He just let her suck it and Xu Sheng was still blindfolded.

Then, in the blink of an eye, another five hundred years passed.

At this time, with the help of Mu Hongling's gentle care, Xu Sheng's cultivation has directly broken through to the late Golden Core Realm!

It's like riding a rocket!

However, Xu Sheng still displayed his cultivation level to the outside world as being in the early stage of the Golden Core Realm.

After all, it's a safe bet.

However, Xu Sheng also had some troubles at this time.

That is, his body has now grown to about fourteen years old.

This age is a very hot-blooded age.

This made it a bit unbearable every time Xu Sheng practiced with Mu Hongling.

However, Mu Hongling still simply used him as a "cultivation tool that can filter the so-called purple spirit crystals".

Xu Sheng was not allowed to do anything else to her.

For example, touching something is totally prohibited.

And Xu Sheng has always followed his master's orders.

He did not rashly do anything inappropriate.

Xu Sheng didn't want to find other women to put out the fire.

Because Xu Sheng had also privately read some classics over the years.

He already knew that the best way for Mu Hongling to absorb the purple spirit crystal was to do the same as the little Taoist nun did before.

These shared bathings today are just a second-best solution that Mu Hongling came up with.

But in fact, the energy refined in this way is relatively not the most efficient.

The energy refined in this way is quite useful for low-level cultivators like Xu Sheng.

But for a powerful virtual immortal like Mu Hongling, it is relatively a drop in the bucket.

Xu Sheng felt that Mu Hongling would have to use a more advanced method one day.

So he didn't look for other women.

It’s better to leave everything to Mu Hongling.

After all, Mu Hongling is so good to Xu Sheng.

Xu Sheng's cultivation level has made so many breakthroughs in such a short period of time.

Xu Sheng thinks that people should be grateful and repay the kindness they have received!

Mu Hongling’s kindness!

He should repay the kindness with gratitude!

But so many years have passed.

Mu Hongling has not taken the initiative to upgrade her refining method.

"Master, I'm actually grown up now!"

That day Xu Sheng couldn't help but ask Mu Hongling: "When can we abandon the old rules?"

"What?"

Mu Hongling's pretty face flushed and she turned to the other side and said, "I haven't thought about this yet."

The formal refining method originally recorded in the classics.

A person with a holy yang body like Xu Sheng would directly swallow the purple spirit crystal powder into his mouth and then refine it.

Then Mu Hongling absorbed energy in the same way as the little Taoist nun did before.

Seeing Mu Hongling say this.

Xu Sheng naturally didn't dare to say anything else.

He just respectfully withdrew.

In the blink of an eye, it was another hundred years later.

After finishing refining the energy, Xu Sheng came to find Mu Hongling again.

"Master, my energy has been refined. Tonight..." Xu Sheng whispered.

"Everything remains the same!" Mu Hongling said with a stern face while her pretty face was slightly moist.

Hear these words.

Xu Sheng was a little disappointed.

After all, he is now a teenager of about fifteen years old.

He is already over 1.7 meters tall.

He has become a real man and is at the most vigorous age.

He thought Mu Hongling would upgrade the method of refining purple spirit crystal.

I didn't expect that she would still continue with the old way.

But Xu Sheng naturally couldn't say anything at this time.

And even though Mu Hongling and Xu Sheng had hugged each other and their lips had touched each other.

But not when refining the purple spirit crystal.

Xu Sheng couldn't even touch Mu Hongling.

Then Xu Sheng prepared to turn around and leave.

But unexpectedly, a flying crane suddenly flew in.

It is a flying crane that Xu Sheng has tamed over the years.

He asked his parents and mother to send letters via the flying crane if they had any problems.

"Um?"

Seeing this, Xu Sheng quickly stretched out his hand.

Feihe flew towards Xu Sheng.

Soon Xu Sheng got the token.

"What?" The next moment Xu Sheng's face changed drastically.

"What's wrong? What happened?" Seeing Xu Sheng's reaction, Mu Hongling beside him couldn't help but ask.

"My mother is in trouble!" Xu Sheng said with a pale face, "She went astray from practicing martial arts!"

That's right.

This is the content of the letter that came with the book.

Xu Sheng's father and mother have not dared to reach the Golden Core stage in all these years.

Because you are not confident enough to survive the fire!

Xu Sheng asked them to wait until he became stronger and then he would find a way to help them.

So they are still waiting.

But no one expected that Xu Sheng’s mother did not die in the fire.

Instead, he went astray while practicing the technique and nearly died.

At this time, Xu Sheng immediately turned around and flew to the area where the inner disciples lived where his father and mother lived.

"I'll take you there."

Of course, I didn't expect that a red-haired figure would flash behind me at this moment.

Mu Hongling's white and tender hand directly grabbed Xu Sheng's left arm.

A burst of magic power shook.

The two men flew through the air.

It was much faster than when Xu Sheng flew by himself.

Soon Mu Hongling brought Xu Sheng to his parents' residence.

"Thank you, Master."

After landing, Xu Sheng thanked him and then rushed inside.

Although Xu Sheng and Mu Hongling had carried out some special cooperation in cultivation.

But the two of them had already agreed on it.

Everything is just for cultivation.

Master and apprentice are still master and apprentice.

Therefore, Xu Sheng usually did not dare to be negligent in showing courtesy to Mu Hongling.

Mu Hongling didn't say anything either.

He just followed Xu Sheng's body and entered the house in a flash.

Xu Sheng saw his father looking at his mother by the bed.

His mother was lying on the bed with a pale face.

"Father, how is Mother?" Xu Sheng asked anxiously.

"The elders from Baicaotang came to see her!" Xu Sheng's father said with tears in his eyes, "But they said it can't be cured! They just treated her and used medicine! Although she didn't die! But from now on, it all depends on your mother's luck! The situation is a bit serious!"

Of course, when he got to this point, Xu Sheng's father saw the slim red-haired Mu Hongling who followed in.

He quickly stood up and said very respectfully: "Disciple greets Elder Mu!"

"No need to be so polite." Mu Hongling put one hand behind her back and raised the other hand and waved it gently.

At this time, Xu Sheng also hurriedly stepped forward and used his magical powers to check on his mother's physical condition.

Soon Xu Sheng's brows also frowned.

He found that his mother's condition was indeed not good!

Because Xu Sheng himself has no special medical abilities at all.

So at this time he could only turn around and look at Mu Hongling next to him.

After all, Mu Hongling is a powerful person at the level of virtual immortal.

Maybe she has some other means.

"Let me take a look."

Mu Hongling didn't waste any words. She walked forward, stretched out her white and tender jade hand, hovered in front of Xu Sheng's mother, and used her magic power to investigate.

When Mu Hongling started to investigate.

Xu Sheng and his father didn't dare to say a word.

"Master, what's the situation? Is there still hope?" Xu Sheng asked only after Mu Hongling withdrew her jade hand.

"The situation is indeed a bit serious. It really cannot be cured by ordinary means."

Mu Hongling frowned and said, "It's no wonder that the people at Baicaotang couldn't cure her."

"What's the meaning?"

Before Xu Sheng could say anything, his father said excitedly, "Elder Mu, do you mean my wife can still be saved?"

Xu Sheng's eyes naturally lit up at the same time.

Although Mu Hongling did not say this directly.

But the two sentences she just said seemed to have this meaning.

"I'm not sure about this either, I can only give it a try."

Mu Hongling pursed her lips and said something.

As she spoke, she glanced at Xu Sheng and her pretty face turned slightly red.

Then she directly asked Xu Sheng's father to leave the room.

Hearing this, Xu Sheng's father scratched the back of his head in confusion.

But he turned around and left without saying anything else.

Only Xu Sheng, Mu Hongling and Xu Sheng's mother who was lying on the bed were left in the room.

"Master, what does this mean?"

Xu Sheng asked, "Is there any treatment method that my father cannot be present for?"

"The only way to save your mother now is to use the power of the Purple Spirit Crystal. This thing is extraordinary! Maybe it can heal the damage your mother has suffered."

Mu Hongling's earlobes were tinged with pink as she explained with a straight face, "And this time we can't use the previous method. We must use the original method recorded in the classics to obtain the purest energy to cure your mother."

"What? What does that mean?" Xu Sheng was stunned again.

I didn't expect that the method Mu Hongling suggested would be like this.

"Just swallow this purple spirit crystal!"

Before Xu Sheng could say anything, Mu Hongling had already taken out a soybean-sized purple spirit crystal and crushed it with her magic power before handing it to Xu Sheng.

"After using your physique to refine it, I will absorb it and refine it again. It should be able to become energy that can save your mother!"

"That."

What else could Xu Sheng say after hearing this? He could only say, "Thank you for your hard work, Master."

Then he swallowed it without any more words.

Then Xu Sheng suddenly felt that the energy of the purple spirit crystal was indeed extraordinary!

It's not like the usual feeling of sprinkling in water and then taking a bath.

After this time in mouth!

After a while, Xu Sheng felt his whole body boiling!

The qi and blood are surging.

It feels like my body is going to explode.

If he wasn't for his extremely yang body.

The body is strong.

It's estimated that it has exploded by now.

Of course, Mu Hongling didn't say anything at this time.

She simply lifted her long red hair and started to do the same thing as the little nun did when she chanted Amitabha.

Of course Mu Hongling is Mu Hongling.

She did not chant Amitabha.

"remember."

She just used her white and tender hands to lift up her thick red hair and said: "Everything is just for refining the purple spirit crystal. There is no special relationship between us!"

"yes."

Xu Shengze also looked at Mu Hongling and said in a very respectful tone: "Disciple, please remember this."
