Mu Qiankun brushed his sleeves away, which made Mu Ling and Master Ouyang a little surprised, they didn't understand, they were so good, why did they suddenly turn their faces?

The women showed pity, and it was obvious that the old guy had been hit again, his self-esteem had been frustrated, and he needed someone to calm down. **Fast Update**

"I'm going to retreat for a while. ”

Zhang Heng said suddenly.

Mu Qiankun wasn't really angry, so he didn't need to worry, and next, his first task was to retreat and practice.

At present, it has come to the opportunity to break through to the late stage of foundation building, and Zhang Heng is naturally unwilling to miss it.

Besides, the elixirs he looted, the bits and pieces on the demon beasts, etc., had already filled the storage bag, whether it was alchemy or refining tools, these things should have been consumed.

"We also have to retreat. ”

Jiang Hongli nodded and said.

She is now a qualified cultivator, but she must still have a process of adapting to the powerful power for the first time.

This was also the case with the other women, but Mu Qing flattened her mouth, and her little face showed a bitter look.

She plays hard, cultivates, alchemy or something, it's not the first place for her, she finally went out to Niuer Mountain, and she hasn't had enough fun, and her brothers and sisters are actually going to retreat.

Helpless, he could only say depressedly: "Okay, I also followed my grandfather to practice." ”

If other cultivators knew about this, they would definitely be angry and smoke, and if someone else had the opportunity to practice immortal skills, they would definitely be so excited that they couldn't do it, and they couldn't wait to spend 365 days a year on this matter, but this girl was not good, and she was reluctant to cultivate immortal skills.

In the end, after Zhang Heng explained some things to Ryoma, Mu Ling and Master Ouyang, he went directly to retreat.

He didn't expect that there would be so many cultivators in Niu'er Mountain before, so he didn't build a redundant meditation room, and there were too many people to squeeze in, but he had to carry forward his style and enter the Earth Fire Palace.

The Earth Fire Palace, like the Alchemy Room, is a relatively special building.

The difference is that one is used for alchemy, and the other is used for refining.

The earth fire was raging, burning incessantly, and as soon as I entered, there was a surging heat rushing to my face.

In the air, there were faint wisps of fire poison spreading.

Ordinary monks retreat in this kind of environment, and if the time is short, it will have no effect, but after a long time, there is a possibility that fire poison will enter the body, and there is a danger of going mad.

However, for Zhang Heng, there is no need to care, there is a Xuantian tree in the dantian, and as soon as the fire poison enters the body, it will be automatically cleaned up.

Sitting cross-legged, Zhang Heng entered the dantian with his thoughts, but he saw a rather strange picture.

In the dantian, a palm-sized tree is intertwined, the branches and leaves are luxuriant, and the leaves shake slightly, giving people a feeling of vitality.

This is the Strange Treasure Xuantian Tree that made Zhang Hengsheng get no matter what, no matter what the price is, and it is also one of the biggest dependents for him to return to the peak.

It has been a long time since he got the Xuantian Tree, and I have to say that this treasure is of great help to Zhang Heng, if it weren't for the Xuantian Tree to detoxify, heal, and several life-and-death battles, it wouldn't be so easy to overcome.

However, Zhang Heng knew that although the current Xuantian Tree already looked against the sky, it was still 108,000 miles behind its mature state!

It's just a matter of healing, and the power exerted is less than one ten-thousandth!

"If you let the Xuantian Tree grow naturally, with its long growth cycle, it will take a thousand years to enter the maturity period, which is obviously not good for me......" Zhang Heng's eyes showed a thoughtful look and muttered: "It seems that I am going to find some wood-attribute spiritual objects that can promote the growth of the Xuantian Tree." ”

At the top of the list, there is no doubt that it is the fragment of the Xuantian Tree.

Roots, leaves, branches...... As long as it is a remnant of the Xuantian Tree, it naturally carries a huge amount of wood attribute aura, and with the same origin, it is easy to fuse.

It's just that such a strange thing as the Xuantian Tree is rare in the world, and Zhang Heng doesn't feel that he still has luck and can get more.

So after thinking about it, you can only retreat to the second.

Other strange trees, spiritual roots, can also be devoured by the Xuantian Tree, speeding up its growth.

It's just that these things are not very easy to find.

Zhang Heng planned to wait until the end of the retreat to ask Mu Qiankun, the old guy had a wide range of friends, maybe there would be news.

Putting aside the matter of Xuantian Tree for the time being, Zhang Heng's gaze swept to the corner of the dantian again.

In the huge dantian, the Xuantian Tree was in the middle, releasing an emerald green brilliance, unceremoniously occupying the most comfortable position.

And the Nine Extremes Killing Immortal Sword Array, this terrifying sword array composed of ninety-nine spiritual weapon flying swords, could only be squeezed into the corner...... This scene, once seen by cultivators, even if they don't know the Xuantian Tree, they will react immediately and know that this little tree is the ultimate treasure!

The Nine Extremes Killing Immortal Sword Formation has already refined twenty-one flying swords, this speed is definitely not fast, the reason for this is that Zhang Heng has been running around, or fighting with people, or has no time to cultivate, and there is no calm refining flying sword at all, so the speed seems to be so slow.

However, there is really no need to worry, this set of sword formations is extremely strong, enough to be invincible in the Jindan period, but the flaws are also obvious...... Zhang Heng's cultivation is insufficient, and using this sword array, I am afraid that his spiritual power will be drained in an instant.

This is also because his exercises are different from ordinary people, his accumulation is abundant, and his spiritual power is dozens of times purer than that of cultivators in the same realm.

"When it comes to the late stage of foundation building, the speed of refining will definitely speed up a lot......," Zhang Heng took a deep breath.

As his cultivation ascended, he realized that the circle he was in would also be constantly changing, and with his temper, it was difficult not to offend Brother Jindan.

If he wants to deal with the Jindan monk, the Nine Extremes Killing Immortal Sword Formation is very important, and it will become one of his most important hole cards.

"Later ...... of Foundation Building"

Zhang Heng waved his hand, and an object appeared in front of him.

It was the Baizhen Turtle he got from Xuanwu Lake, and for this turtle, it set off a lot of turmoil.

If it weren't for his extraordinary strength, I'm afraid that he would really suffer a big loss at the hands of the Rakshasa thieves.

"With this thing, it should be a matter of course to break through to the later stage of foundation building. ”

Zhang Heng muttered to himself, but he threw out the three talents gathering Lingding.

Ding into the earth fire, up and down in the sea of fire, Zhang Heng flicked his fingers, and the prepared spiritual spring water shot into the Ding furnace.

After a while, the water splashed and boiled, and Zhang Heng threw the Baizhen turtle into it.

Boom!

The stove was covered and continued to roast in the sea of fire, while Zhang Heng closed his eyes and waited silently.

The instrument spirit of the Sancai Gathering Spirit Ding emerged, but his face was full of grievances, he glanced at Zhang Heng, and dared not speak angrily.

As a Danzun Danding, no matter who gets it, it must be treated with courtesy and regarded as a treasure, but Zhang Heng is the only one who uses it to refine a puppet and use it as a defensive magic weapon, and now, he even uses it to make soup.

"Dignity swept away......" he muttered twice, and then shrank back into the danding.

He has been following Zhang Heng for a while, and he naturally knows very well what the character of this new master is.

Resist, there must be no way out, and he has no intention of resisting, following this promising master, maybe he can keep the clouds open and see the moon, and there may not be another creation.

Two hours later, a refreshing fragrance wafted out of the danding.

This fragrance was simply incomparable, spreading ten miles away, and Master Ouyang, who was drinking tea outside, changed slightly.

"What does it smell like?"

Mu Ling also turned his head and looked in the direction of Zhang Heng's retreat, frowning slightly: "What is Shizun doing?"

Ryoma shrugged his nose and looked intoxicated.

In the medicine field, like an old farmer, he leaned down and was observing Mu Qiankun, who was observing the medicine spirit, but he showed a helpless look.

"The smell of the Hundred Treasures Turtle, how many good things are there on this kid?"

He was surprised when he discovered the medicine spirit just now, but now that he smelled the fragrance of the Baizhen Turtle, he was not much shocked, he was already a little numb, and felt that no matter how incredible something happened to Zhang Heng, it was so natural.

Zhang Heng raised his hand and led it, and the three talents gathered the spirit tripod from the sea of fire, and the tripod lid flew away on its own.

The fragrance is a hundred times richer, and it gushes out suddenly.

Zhang Heng's index finger moved, directly picked up the Danding, and poured it into his mouth.

A pot of broth, swallowed it all into his stomach, he wiped his mouth, and at the same time, an explosive force spread out in his body!
