Back at the Mu family, Mu Qingshan's attitude towards Gu Lin was obviously much more respectful.

Holding the tea in his hand, Mu Qingshan twisted his beard and smiled at Gu Lin: "Gu Lin Xiaoyou, but the old man has been looking away, but I didn't expect you to hide it deeply!"

Gu Lin hugged his fists and said with a smile: "Uncle Qingshan is too polite, and Gu Lin also inadvertently made a splash." ”

After speaking, Gu Lin's eyes deliberately swept over the tall and mature xylophone concubine in a red dress on the side.

Seeing this, Concubine Muqin suddenly clenched her silver teeth, and her jade hand was hugged in front of her chest, with a look of indignation.

Putting the teacup down, Mu Qingshan seemed to suddenly remember something, and his face suddenly became solemn: "Gu Lin Xiaoyou, the old man didn't want to tell you about this, but now it seems that I underestimated you." I don't know if you've heard of the 'Immortal Domain' that has been rumored in Wind Thunder City recently?"

"The Undead Domain?"

Hearing this, Gu Lin suddenly looked suspicious and muttered in his mouth.

He has been living in Wind Thunder City since he crossed over, and he can also be said to be a person from Wind Thunder City.

But he has been a loner, visiting tombs everywhere, and he doesn't know much about some of the strange things in Wind Thunder City.

Looking at Gu Lin's doubts, Mu Qingshan nodded solemnly and said, "Yes, Immortal Domain! Someone found a strange place in the Ten Desolation Medicine Mountain. Stepping here, some stubborn cultivation diseases, and many years of illness, were able to be cured. There are even some rumors that I don't know whether it is true or not, and there are even dead bodies in that place...... Resurrection!"

Speaking of this, Mu Qingshan's face couldn't help but become extremely strange. Obviously, such a thing as resurrection from the dead, Rao has lived most of his life, and he also feels absurd.

"Resurrection from the Dead......"

Gu Lin couldn't help frowning, this kind of thing is against the common sense of the Aura Continent, even if the Blood Flame Worm is just a reunion of the primordial gods, it can't talk about resurrection from the dead!

"Why did Uncle Qingshan suddenly mention this immortal domain?"

Mu Qingshan slowly put down the teacup in his hand, and said with a deep face: "That immortal domain has been discovered for several months, and many people suspect that there may be a large tomb and ancient tomb underground, and there are strange things buried in the tomb, which causes this kind of anomaly. However, Wind Thunder City didn't know how many tomb explorers had been exploring for months, and there were even many veteran tomb explorers from the three major forces such as the Heavenly Tomb Pavilion, but they all found nothing!"

Speaking of this, Mu Qingshan paused and continued: "Recently, the Immortal Domain has finally alarmed the Medicine Emperor Mountain Branch, and Elder Wuming, one of the three elders, has called on many tomb exploration masters to prepare to enter the Ten Desolate Medicine Mountains to find out. If you are interested, you can go with me. If you are chosen by Elder Wuming, I believe that the reward will definitely satisfy you!"

Looking at the strange light in Mu Qingshan's eyes, Gu Lin could see that even Mu Qingshan was extremely moved by the reward offered by Elder Wuming.

However, Gu Lin was a little hesitant, after all, the Immortal Domain was mysterious and unknown, although there may be great opportunities, but there will be no less danger.

Not to mention anything else, the violent and powerful spirit beasts in the Ten Desolate Medicine Mountains were enough for them to drink a pot.

When Gu Lin hesitated in his heart, a voice suddenly sounded in his head.

"Hearing him say so mysterious, I suddenly remembered something. You can take a look at that undead domain. ”

Hearing that it was the voice of the Blood Flame Insect, Gu Lin saw its primordial spirit floating on the corpse of the insect, and frowned slightly: "Don't you think this thing is too weird? Such an evil thing as resurrection from the dead is a bit too absurd!"

The Blood Flame Worm smiled and said, "What kind of death and resurrection, don't listen to his nonsense, most of it is your Wind Thunder City that is spreading falsehoods." How can there be any resurrection from the dead? Even I was just lucky enough to be reunited. ”

The Blood Flame Worm seemed to be quite curious about the Immortal Domain, and seeing that Gu Lin was still hesitant, he added another fire and said: "You need a lot of elixir to upgrade the medicine witch worm in your body, although you have a lot of elixir this time, it is far from enough. If you can really find something precious in the Immortal Realm, you can also exchange it for more elixir. ”

I didn't understand why this guy was so encouraging him, but Gu Lin thought about the large amount of elixir he needed, and after thinking about it for a while, he finally nodded slowly.

After all, even if the Blood Flame Worm induces itself a little, it still needs to help him find an elixir to nourish the Yuan Shen, and it shouldn't push itself into the fire pit. And this guy seems to have seen something in the Undead Domain.

Thinking of this, Gu Lin hugged Mu Qingshan and said with a smile: "Uncle Qingshan, Gu Lin is willing to go with you, but I don't know when to leave?"

Mu Qingshan stroked his beard and smiled: "This is not in a hurry, Elder Wuming should leave tomorrow, so it is not too late for us to go to the Medicine Emperor Mountain Branch tomorrow morning." Gu Lin Xiaoyou, let's have a good rest tonight!"

After a few more polite words with Mu Qingshan, Gu Lin slowly withdrew from the hall and returned to his room.

I'm going to the Immortal Realm tomorrow, and I'm afraid that this place will be a bit dangerous, so it's better to improve your strength first.

The medicine witch worm in Gu Lin's body had already reached the peak of the first order, and his strength had also been raised to the seventh order of Linghuang, just one step away from Lingxuan.

Therefore, as long as the elixir was fed to the second order, Gu Lin would be able to break through.

Thinking of this, Gu Lin took out all the dozens of first-class elixirs obtained from the sale.

As soon as the elixir was taken out, the eyes of the Blood Flame Worm suddenly lit up, he was just gathering his primordial spirit, and the nourishment of the elixir was too important to it!

Feeling the coveted look on the face of the Blood Flame Insect, Gu Lin pursed his lips and said lightly, "Say, how many elixirs do you need?"

The Blood Flame Worm was silent for a moment before sneering slowly: "You don't need to give me too much, forty is about the same." ”

"What...... What?!"

Hearing this, Gu Lin stumbled for a while, and almost fell to the ground.

I entered the ancient tomb of the Purple Witch Fire Wooden Coffin, and I exchanged more than seventy elixirs for nine deaths, and this guy actually asked for forty plants when he opened his mouth!

"Damn, I didn't, you guy is too embarrassed, right?"

The Blood Flame Worm also seemed to feel that the request was a bit excessive, and smiled embarrassedly: "This...... Everyone is their own person, I don't see you, and you don't want to be too polite to me, isn't ......"

"I'm polite to you......"

The corners of Gu Lin's mouth twitched fiercely, and he suddenly realized that this guy was so brazen.

Seeing that the elixir couldn't be sought, the Blood Flame Worm was anxious, and his eyes rolled a few times before he smiled: "Don't forget, I can help you upgrade your Medicine Witch Worm's bloodline to the third order." You can't afford to pay some elixir, it's too petty!"

"Don't keep talking about medicine witch worms, who knows if what you said is true or false? Unless you upgrade its bloodline now, there will be forty elixirs, and there will be no door!"

The Blood Flame Worm had a look of anger on its face, although it could upgrade the bloodline of the Medicine Witch Insect, but it had to wait for the Medicine Witch Worm level to reach the peak of the second order, and now it had no choice.

Frowning and thinking for a long time, the Blood Flame Worm finally pouted helplessly: "Okay, I'll tell you the secret of a bronze ancient stone I found, you give me the elixir, it's all right?"

"The secret of the bronze stone?"

Gu Lin couldn't help but be stunned, the bronze ancient stone was obtained by him from the ground by accident, and he didn't know the origin.

However, even the primordial spirit of the Blood Flame Worm can be reunited with this, and the origin of the bronze ancient stone is probably not simple!

After struggling in his heart for a long time, Gu Lin nodded slowly and said, "Okay, but you say it first, if it's a real elixir, it's not too late to give it to you!"

"You're a little too cautious, aren't you?"

The Blood Flame Worm rolled his eyes at Gu Lin, and said with a look of contempt: "Leave me forty elixirs first, and feed the rest to the medicine witch worms, whether there is any change in the bronze ancient stone, we will see in a while." ”

Gu Lin didn't know whether his words were true or false, but feeding the medicine witch worm was exactly what Gu Lin thought, so he didn't hesitate too much.

Ten first-class elixirs were instantly sent to the mouth of the medicine witch insect by Gu Lin, the medicine witch insect had no attack power, but there was a kind of love for the elixir, and the ten elixirs were swallowed in the blink of an eye.

The medicine witch worm in Gu Lin's body has reached the peak of the first order, and under the stimulation of the ten elixirs, it has finally undergone a transformation and is about to advance!

The body began to glow red, and the medicine witch worm slowly expanded a little, Gu Lin knew that it was about to break through, and he did not skimp on the elixir, and more than a dozen elixirs were handed over.

In the blink of an eye, apart from the forty elixirs left for the Blood Flame Worm, Gu Lin only had less than ten elixirs left.

Devouring so many elixirs, the breakthrough barrier that was close at hand was finally broken, and the medicine witch worm naturally broke through to the second order!

Feeling his power rising as the Medicine Witch Worm advanced, Gu Lin's face suddenly showed ecstasy.

This is where the great value of the Medicine Witch Worm lies! As long as the refiner feeds it enough elixir, its strength can keep pace with it.

And it seems that even the heavens feel that this function is too terrifying, so the medicine witch worm is almost extinct, and there are almost no bloodlines that can finally be upgraded to the third order, anyway, Gu Lin has never heard of it.

Therefore, when he heard that the Blood Flame Worm could upgrade the Medicine Witch Worm, Gu Lin was so excited to let it stay in his body and collect elixir for it.

Feeling that his strength had been raised to the first level of Lingxuan, a smile had just appeared on the corner of Gu Lin's mouth, and the voice of the Blood Flame Insect suddenly sounded.

"Quick, you still have some residual medicinal power in your body, even if the medicine witch worm devours it, it won't be enough to advance, quickly merge this medicinal power into the bronze ancient stone!"

Gu Lin was not lazy, and fused the remaining little medicinal power into the bronze ancient stone in his body.

The bronze ancient stone was only the size of a palm, but Gu Lin had already discovered that there were four small but incomparably deep doors on it.

One of the flame-shaped doors immediately sucked the medicinal power in, and the flame door immediately showed a slight fluctuation to the extreme, and finally everything was calm again.

"What's going on? No reaction at all?"

The Blood Flame Worm's face was slightly solemn and said, "Your Yuan Shen is still too weak, and you can't feel this kind of insignificant change to the extreme." In fact, the flame door has been slightly opened, of course, this trace can basically be ignored. But my idea was confirmed!"

Looking at Gu Lin's suspicious expression, the Blood Flame Worm continued: "According to this trend, continue to inject medicinal power inside, and the flame door should be able to open." And what is behind the door is probably going to be very unusual!"

"How many elixirs do you need?"

Gu Lin knew that just now there were dozens of elixirs left in their medicinal power, and even he couldn't detect the signs of the flame gate moving.

And if you want to open it completely, the amount of elixir needed is probably unimaginable!

"It shouldn't take much, this flame gate seems to have absorbed a lot of aura before, and now it seems to be the last straw!"

Gu Lin breathed a sigh of relief in his heart, if this was the case, he could still reluctantly accept it.

But now it seems that the elixir has become the most urgent thing for him.

However, seeing that this guy didn't break his promise, although Gu Lin was extremely painful, he still handed over forty elixirs, after all, the temptation of the bloodline upgrade of the medicine witch insect was too great!

"Ah, elixir...... Here you go!"

Gu Lin tearfully took out forty elixirs, trembling in distress.

"You guy instigated me to go to the Immortal Domain, do you know how dangerous it is in the depths of the Ten Desolate Medicine Mountains? Wind Thunder City, but the strong people in the Spirit Land have all died in the hands of the spirit beasts in the Medicine Mountain! I am only the strength of the first order of the Spirit Xuan, and I am afraid that if I go, I will die for a lifetime!"

The Blood Flame Worm rolled its eyes at Gu Lin, the blood-colored flame suddenly rose, and said a little proudly: "My body is dead, although my strength is no longer able to exert itself, but with this blood-colored flame alone, I still see one burning one in the spiritual realm!"

Gu Lin was silent on the surface, but he couldn't help but feel a burst of joy in his heart.

I complained about my suffering for a long time, isn't that what I want?

Otherwise, he wouldn't be stupid enough to run to a hellish place like the Undead Domain.

The Blood Flame Worm also seemed to see what Gu Lin was thinking, and suddenly said with a helpless dry smile: "You guy......"
