The magic crystal is the currency of the Demon Realm, which is equivalent to the spirit stone of the Upper Realm, and these are all learned during the time that Ming Jiutian stayed in the Demon Realm.

However, he didn't expect that a five-grade elixir was actually worth 100,000 pieces in the demon world, and a high-grade magic crystal might not be able to be bought.

This is simply too exaggerated, and I didn't expect that the Demon Realm has always exchanged for pills through this method.

"What if it's a seven-grade one?" Ming Jiutian asked tentatively.

"Seven-pinned pills rarely appear in the demon world, I remember hearing my grandfather say it once, if it is a seven-pinned elixir, then it is not something that can be bought by magic crystals, and it is conservatively estimated that it will also require more precious things," Princess Night introduced.

These words prompted Ming Jiutian, if one day the upper realm can't go on, with his alchemy methods, he must be very comfortable to go to the demon realm.

"I didn't expect the conditions in your demon realm to be so difficult, but now it's okay, as long as he is here, all kinds of pills are enough" Dugu Yanran pointed to Ming Jiutian and said with a smile.

"So, he's rich?" The Night Princess looked at Ming Jiutian with a look of surprise.

"Haha... That is, he is the youngest God in the Upper Realm, sitting on the Four Heavenly Domains, and the Natural Chamber of Commerce, one of the four major chambers of commerce in the Upper Realm, is also his, who is rich if he is not rich? Hua Ruyan echoed.

"And he doesn't have to buy the pills at all, these pills are all refined by himself, haha..."

Come on, there is no secret at all in the nine days of tomorrow, and it was all told by the women.

"You're still an alchemist?" The Night Princess was surprised again.

"It's just a hobby, that... I'm going to go to the Supreme Emperor Domain in a few days, and before I leave, I plan you to take you around and meet my parents," Ming Jiutian scratched his head a little shyly and proposed.

As soon as Ming Jiutian's words came out, the girls instantly turned red, and they were about to see Ming Jiutian's parents, and they were inevitably apprehensive.

Since it has been decided, in order to save time, in the afternoon of the same day, Ming Jiutian took a group of people to the teleportation array to Yue Hengtian.

Because it is a teleportation array of the Natural Chamber of Commerce, it only takes three days to arrive.

There was nothing to do all the way, and three days later, the Void Shuttle of Ming Jiutian appeared on the teleportation array on the mountain opposite the Yueheng Heavenly Lord's Mansion, and the people of the Natural Chamber of Commerce seemed to have received the news a long time ago and had been waiting for a long time.

As soon as they walked to the gate of the Lord's Mansion, Ming Qixiu and Ouyang Lanxin walked out, looking at the vast group of daughters-in-law in front of them, the two of them were very happy.

Especially seeing that Ye Ziling and Yang Yuer still have big bellies, let alone how happy they are.

Today, more than a hundred years have passed, and the family is barely together, and the happy ending is naturally indispensable, although the girls are a little shy when they see their mother-in-law, they will soon let go.

At this time, Hu Yuan came from a distance, but he didn't get close to here, he just stood in the distance and beckoned, as if he was unwilling to break the short-term auspiciousness of the Ming Jiutian family.

Ming Jiutian naturally understood, and after a few simple explanations, he walked towards Hu Yuan.

"Young Master, the matter is clear" Hu Yuan saw Ming Jiutian coming over, and immediately bowed down and said.

"Oh? Let's talk about it..."Ming Jiutian found a place and sat down.

"After receiving the news from Brother Ning, my people and the Natural Chamber of Commerce conducted a secret investigation in the upper realm, the specific location of this Heavenly Sword Sect is in Kong Shengtian, the head of the sect is named Du Qingyuan, and he has just entered the realm of the late stage of the Holy Emperor, but..."

"But what?" Looking at Hu Yuan's expression, Ming Jiutian knew that Hu Yuan must have something else to say.

"However, this Du Qingyuan has been living a life of idle clouds and wild cranes since he took over the position of the head of the Heavenly Sword Sect, and all the affairs in the sect are in charge of his younger brother, and this Du Qingyuan is close friends with the Wenju Heavenly Lord Min Wenxuan, will we do it directly?" Hu Yuan said the worry in his heart.

Hearing Hu Yuan's words, Ming Jiutian also fell into deep thought, Mo Yunfei and Yan had to be explained for their frightening.

But if you want someone to take revenge, you must at least find the culprit, you can't just kill all the people from the Heavenly Sword Sect.

Moreover, Du Qingyuan has a good relationship with Min Wenxuan, and if he makes a rash move, it will easily cause a chain reaction.

"What else did you find?" After pondering for a moment, Ming Jiutian continued to ask.

"I also found out that Du Qingyuan is usually a person who is against poetry in addition to playing in the mountains and rivers, and he has not asked about all kinds of disputes in the upper realm for a long time, until his younger brother Du Wenzhao is ruthless, treacherous and changeable, and he is an out-and-out villain, and it is because this Du Wenzhao coveted Siyun's sister's appearance that it caused these behind" Hu Yuan heard the words and spoke again.

"It seems that the situation is already clear, how is the manpower arranged?" Ming Jiutian thought about it, but decided to do it first.

The current situation couldn't be clearer, and it is estimated that this Du Wenzhao did it nine times out of ten, so he simply took advantage of the time to leave.

"Back to the young master's words, the Supreme Saint Emperor brought more than 2,000 people on this trip, twelve people in the late middle and late stages of the Holy Emperor, eighteen Li brothers, and two thousand people from Jianfeng's newly formed Wind Chasing Arrow Team, and now the Qingtian Sword Sect is surrounded, just waiting for the young master to give an order" Hu Yuan also made a categorical gesture when he heard this.

Ming Jiutian was taken aback when he heard this, what are you kidding, this is not going to fight a large-scale battle, as for bringing so many people.

But come to think of it, the Four Heavens are still the Four Heavens on the surface, but in fact, they have already been united in private, and this lineup is estimated to be able to sweep any Celestial Domain.

Coincidentally, although Ming Jiutian himself has not been to Kong Shengtian, this Kong Shengtian is next to Yue Hengtian.

It was said before that if the strength is reached, it is possible to pass directly through the boundary sea, and if you take the teleportation array, it will be enough for half a day.

Hu Yuan went to Kong Shengtian first, and Ming Jiutian went back to attend the family dinner.

Seeing the harmony of the family, Ming Jiutian also hoped that it could continue like this, and looked at the time, it was time to go out and run errands.

Ming Jiutian casually found an excuse and went out, and three hours later, he appeared in the main city of Kong Shengtian, Worship Sword City.

Hu Yuan had been waiting here for a long time, and when he saw Ming Jiutian appear, he hurriedly stepped forward.

"Young Master, it's all ready..."Hu Yuan muttered in a low voice.

"Okay, let's lead the way" Ming Jiutian waved his hand, and the two of them disappeared into the night.

Soon, under the leadership of Hu Yuan, the two of them walked towards a mountain peak that was like a sharp sword reaching into the sky.

Walking to the depths of the dense forest, he soon saw the people who were ambushed here, and it was really as Hu Yuan said, these people in front of him surrounded the entire Optimus Sword Sect.

"We're here to take revenge, not to carry out a massacre, pass the order, shrink the defense, as long as you don't let go of the culprit" Ming Jiutian finished speaking, and walked towards the mountain gate of the Heavenly Sword Sect.

Looking at the brightly lit Optimus Sword Sect, it was so late, it was really lively, although the scale of the Optimus Sword Sect in front of him was not as grand as the Five Elements Gate, but all kinds of pavilions, pavilions, carved railings and jade masonry could be regarded as magnificent.

"Stop, who's coming? Don't you report your name soon..."

Soon Ming Jiutian was discovered by the disciples of the Heavenly Sword Sect who patrolled the mountain.

"There's a lot of nonsense, tell you that the one in charge of things is here to take revenge," Ming Jiutian said impatiently.

"Looking for death..."

When the five or six mountain patrol disciples heard this, they pulled out the long sword behind their backs and rushed towards Ming Jiutian.
