"Disciple Xu Mu, meet the master!" Xu Mu bowed slightly and solemnly saluted Zhang Chunfeng, who was high in the Tianxin Palace.

"No need to be polite." Zhang Chunfeng pushed the wide sleeves of his coat in front of him, "Daoyi, Qiushui, you all come in!"

Gou Daoyi and Bai Qiushui glanced at each other outside the hall gate and stood not far from Xu Mu.

"I heard your master say that your Dao foundation is damaged. He used a secret method to barely restrain the Dao Ji from breaking." Zhang Chunfeng stepped down from the high position, and there was a worry between his eyebrows that could not be concealed.

"Master doesn't need to worry, the disciple is already much better. If you don't do anything with people, the Doji will fall into decay more slowly." Xu Mu thought about it for a while and decided to answer truthfully.

"Senior nephew Xu, your Dao foundation is damaged, after entering the Xuantian Secret Realm, remember to fight less with others, and less spells to fight......" Gou Daoyi sighed and told with concern.

Bai Qiushui raised his head slightly, looking at Xu Mu's gray hair, his lips opened slightly, and an inexplicable thought appeared in his heart, "I've always heard from Master that there is a problem with Senior Brother Xu's cultivation, but I didn't expect the problem to be so big......."

Xu Mu seemed to know what Bai Qiushui and the others were thinking, and he raised his eyebrows and smiled, with a mature and mysterious temperament.

"Thank you, uncle, I have my own measure in the matter of my disciple. Qianyuanguan's kendo inheritance, I haven't revitalized it yet, and I won't die so easily!"

"It's good if you think so. Today, I will hand over to you the token that leads to the Xuantian Secret Realm." Zhang Chunfeng smiled gently, and his solemn expression gradually eased.

A wooden plaque glowing with blue light floated from his palm and slowly flew towards Xu Mu.

Xu Mu thanked him, took a deep breath, took the wooden card in his hand, and looked through it carefully.

Heavy and antique, it slightly exudes a faint but distant atmosphere.

The wooden sign is cyan and crystal clear, I don't know what kind of wooden spiritual material it is refined!

The front side is imprinted with the imprint of a volcano, and the reverse side is engraved with Xu Mu's name with an ancient seal.

"Xiao Mu, you drip a drop of essence blood, and I will help you imprint your soul on the wooden card." Zhang Chunfeng said.

Xu Mu said "um", held the cyan wooden card with his left hand, and tapped his right hand slightly in his heart.

A drop of bright red essence blood was forced out of his mouth and dripped onto the wooden sign.

The divine thought moved slightly, and a trace of divine consciousness was condensed in the soul of his mind, wrapped in the drop of essence blood, spinning back and forth, and he could not enter the wooden card no matter what.

"Xiao Mu don't force it, just use his divine thoughts to protect his own drop of essence and blood. For the rest, let me do it!" Zhang Chunfeng waved his hand and made a purple seal.

The purple seal mana was gentle, pushing Xu Mu's divine thoughts and essence blood, and infiltrated the cyan wooden card little by little.

In this way, there are about 30 breaths.

The blue light on the wooden sign suddenly flourished, and quickly collapsed and condensed, and finally the blue light disappeared into the inner side of the wooden card.

The drop of essence blood that Xu Mu forced out had already come to the back of the wooden card, turning into the shape of a fingerprint, flashing with a light red light from time to time.

Zhang Chunfeng stopped the spell and looked at Xu Mu with a smile, "It's okay. You try it."

Xu Mu breathed a sigh of relief, nodded gratefully to Zhang Chunfeng, and punched a wisp of mana onto the red fingerprint inside the wooden card.

The volcanic imprint on the front of the wooden plaque erupted a blood-red flame.

It was like the volcano was erupting!

"A wooden plaque can only soak a drop of essence blood, and when the blood is exhausted, it will be wasted. Don't forget to put it away." Zhang Chunfeng told Xu Mu to put away the wooden card.

Xu Mu put it away as he said, and after hesitating for a few breaths, he said, "Master, you only said the Xuantian Secret Realm, dare to ask the Xuantian Secret Cave......?"

Zhang Chunfeng frowned, and his voice became full of memories, "In your storage bag, the one on the front of the wooden card is the Xuantian Secret Cave!"

After a pause, he looked at Xu Mu and the three of them again, and spoke in a soft tone.

The Xuantian Secret Cave is a dangerous place of life and death in the Xuantian Secret Realm, and it has always been in and out.

If Xu Mu wants to do something, he must think twice before acting.

"Master, the Xuantian Secret Realm opens every six hundred years and ten jiazi, how can I come out after entering?" Xu Mu scratched his gray hair and asked a key question.

"I don't know the exact situation." Zhang Chunfeng shook his head, "I've only read a few words from ancient books."

With that, he handed a jade slip to Xu Mu's hand, "I have prepared the map to the Xuantian Secret Realm and the contents of the ancient books. You can refer to it for yourself."

Xu Mu was also not polite, took the jade slip, and probed his divine thoughts into it, "Master, what do you need me to do for the sect?"

Zhang Chunfeng shook the dust, smiled and explained to Xu Mu directly.

"You are qualified to enter it, and you naturally have your fate. Neither the sect nor I have any other requirements for you. However, according to the regulations, you need to hand over half of the harvest to the sect."

"Half?! I'm desperate to ......" Xu Mu was shocked when he heard that ratio!

"Why, you don't want to?!" Gou Daoyi said viciously behind Xu Mu, "You don't want anyone else to wait......

"I'm willing, I'm willing, it's just a bit too much!" Xu Mu had a distressed and painful expression.

"Oh. I didn't make it clear, according to the rules of the sect, you only need to hand over half of the elixir obtained in the secret realm." Zhang Chunfeng glared at Xu Mu.

A subtext, the Tianyan Sect Sect Master did not say explicitly, "Within the Xuantian Secret Realm, all the gains except for the elixir belong to the individual!"

Xu Mu was so smart, he had already heard Zhang Chunfeng's voice, and hurriedly bowed down and said yes.

"Master, when will Xiao Mu leave?" Gou Daoyi glanced outside the Tianxin Palace.

"Today. I observed the celestial phenomena last night and found that the celestial noble star was moving eastward, so I hope that it should be in line with Xiao Mu's appearance." Zhang Chunfeng stared at Xu Mudao.

"The disciple is willing to go!" Xu Mu did not hesitate to pick up.

The trip to the Xuantian Secret Realm is related to whether he can completely find a way to heal the damage of the Dao Foundation, and it also determines how far he can go on the road of cultivating immortals!

Therefore, he did not hesitate in the slightest!

Zhang Chunfeng pondered for a few breaths, sent Gou Daoyi and Bai Qiushui away, and said to Xu Mu alone:

"It is rumored that there is an opportunity to become an immortal in the Xuantian Secret Cave, and many capable people have died in it for thousands of years. Don't covet the opportunity inside, it is important to save your life!"

"I'll just say that the Xuantian Secret Cave won't be so simple!" Xu Mu whispered in his heart, trembling with excitement.

Cultivating to become an immortal is the greatest pursuit in his heart since he crossed over to this other world!

Otherwise, he wouldn't be so crazy in his cultivation!

Accustomed to seeing the short lifespan of human beings on the earth for a hundred years, Xu Mu cherishes being able to cultivate here!

Crazy scroll cultivation has long become his norm!

Half an hour later, it was still not yet dawn!

Xu Mu said goodbye to Zhang Chunfeng, Gou Daoyi, Han Su and others, and embarked on a journey to the Xuantian Secret Realm alone!

It's a pity that when he went to the stone house residence, he knocked on Qi Huanzhang's door for a long time, but no one answered!

Xu Mu's sword path cultivation at the moment is in the realm, and in the six heavens of the swordsman realm, he can't fly with a sword! Z.br>

I had to rely on my feet and run hard with my physical strength!

Zhang Chunfeng only explained to him the approximate time when the Xuantian Secret Realm would open, but there was no specific and clear information to provide!

Xu Mu tightened a string in his heart, and he ran all the way, like a race against life, for fear of missing the opportunity for the opening of the secret realm!

As for how to come out after entering the secret realm, he doesn't know, Zhang Chunfeng doesn't know, and there is no specific record in the ancient books!

Everything, I have to wait until I enter the secret realm, and then I will see the opportunity to act!

A month later, Xu Mu used the disguise technique granted to him by Cai Yu to change his original appearance.

Along the way, while running, I asked about adjusting the route.

Finally, when it was close to noon on this day, I came to a tall mountain range that towered into the clouds!

"This Daoist brother, dare to ask if you are also here to explore the Xuantian Secret Realm?" A somewhat familiar voice came from behind an ancient tree.
