On the Dragon Temple Square, Feng Wuchen was looking at the Nine-Fold Qiankun Tower, and he didn't know what he was thinking.

After killing the Heavenly Machine, Feng Wuchen returned to the Dragon Temple.

"Brother Feng, what are you looking at the Qiankun Tower?" Ling Xiaoxiao asked curiously, her beautiful eyes also looking at the nine-fold Qiankun Pagoda in mid-air.

But Ling Xiaoxiao didn't see anything.

"Xiaoxiao, I'm wondering if if I use the power of time to speed up the flow of time, will it give us more time?" asked Feng Wuchen.

Hearing this, Ling Xiaoxiao was stunned for a moment, and said embarrassedly: "Brother Feng, I don't understand very well. ”

"The seventh layer of the Qiankun Pagoda has five times the cultivation time, to put it bluntly, the time flow of the seventh layer space is five times faster than that of the outer world. Feng Wuchen said carefully.

"Well, then what?" Ling Xiaoxiao listened carefully.

Feng Wuchen said: "My power of time can control the speed of time, and even make time go backwards, since the seventh layer of space is to speed up the flow of time, I can also do this, think about it, if I integrate the power of time into the fifth layer of space, will this be an extra cultivation treasure land?"

Ling Xiaoxiao frowned slightly, and after thinking for a moment, she nodded: "Listening to what Brother Feng said, it seems to make sense, the space on the seventh floor is too small, if you can make a larger space, Qingyang's cultivation will soon be able to improve." ”

"Having said that, it's hard to do, it's not enough to integrate the power of time into the fifth layer of space, which requires a magic circle to maintain, which can be arranged with the help of the magic circle of the seventh layer of space, but the formation of the seventh layer of space, I have never been able to figure it out. Feng Wuchen shook his head and said.

After a pause, Feng Wuchen said again: "And the seventh layer of space is very mysterious, the flow of time is five times that of the outside, but we don't feel it after we enter, and although my time power can speed up the flow, the movement of people will also speed up, and this is the most difficult part." ”

"That should be the relationship of the formation. Ling Xiaoxiao affirmed.

"Yes, I've been studying the formation of the seventh layer space for the past two days, but unfortunately I don't have a clue at all. Feng Wuchen said helplessly.

Ling Xiaoxiao chuckled and said: "Brother Feng, this kind of thing can't be rushed, the more anxious you are, the more you can't figure it out, sometimes, there are some things that you don't think about, but you understand it unintentionally." ”

"What is the reason?" Feng Wuchen looked at Ling Xiaoxiao in surprise.

"Go with the flow. Ling Xiaoxiao smiled smugly.

Feng Wuchen shrugged his shoulders and said with a smile: "Okay, Xiaoxiao has a point. ”

"Brother Feng is studying slowly, I want to go to cultivation and break through the Heavenly Monarch Realm as soon as possible, but I can't let Brother Feng surpass me too far. Ling Xiaoxiao smiled playfully, then kissed Feng Wuchen's face, and entered the Ninefold Qiankun Tower.

"I didn't kiss it, so I ran away. Feng Wuchen smiled helplessly.

"The hosts. Feng Wuchen's voice fell, and the respectful voice of Qiankun Tower came.

"Huh?" Feng Wuchen raised his eyebrows, and hurriedly said, "Yes, I almost forgot that you know the Qiankun Tower best." ”

"The formation of the seventh layer of space of the Qiankun Tower is a special formation set up by Ling Xuzi, and the reason why the seventh layer of space can be created is that Ling Xuzi fuses the power of time with the special formation, and the function of the formation is to make the accelerated flow time become still, and then there is the seventh layer of space. Qiankun Tower said respectfully.

"The key lies in the formation, do you know the structure of the formation?" asked Feng Wuchen.

"Yes, I'll pass it on to my master. Qiankun Tower immediately transmitted the information of the special formation into Feng Wuchen's mind.

The information of the special formation poured into his mind, and the incomparably wonderful, all-encompassing formation structure was extremely complex, which surprised Feng Wuchen, and secretly marveled at Ling Xuzi's high attainments in the formation.

"What a subtle formation!" Feng Wuchen couldn't help but exclaim, his heart was extremely shocked.

"Yin and Yang, Eight Gates, Life and Death, Taiyi Two Poles, the essence of various formations! How long does it take to study this formation?" Feng Wuchen was shocked, dumbfounded.

"Ethereal Stone?" Feng Wuchen frowned slightly, and said, "I have never heard of Ethereal Stone, and there is no Ethereal Stone in Long Zun's memory, this is the most important material for arranging the formation, and other materials are not difficult." ”

"The Ethereal Stone is a very special spar that can suppress the flow of time, Gu Tongtian is the president of the Chamber of Commerce, and the master can ask him. A voice came from the Qiankun Tower.

Feng Wuchen nodded slightly, and immediately flew to the Chamber of Commerce.

Gu Tongtian and others built the palace of the Chamber of Commerce, and they have been directing the construction work during this time.

The Chamber of Commerce Palace is huge, and the amount of work is very huge, and it takes a lot of time.

"President Koo. Before anyone arrived, the sound of wind and dust had already come.

"Lord Feng?" Gu Tongtian and the three elders who were commanding looked at Feng Wuchen in surprise.

"President Gu, there's something I want to ask you. "The wind is dustless.

"Please speak, Lord Wind. Gu Tongtian said with a smile.

Feng Wuchen asked, "Have you heard of the Ethereal Spirit Stone?"

"Ethereal Spirit Stone?" Gu Tongtian was stunned for a moment, and asked suspiciously, "What does Lord Feng want the Ethereal Spirit Stone for?"

"Does President Gu know about the Ethereal Stone?" Feng Wuchen was immediately overjoyed.

Gu Tongtian nodded and said: "The Ethereal Stone is a very special spar, which is said to be able to control the flow of time and is specially used to refine space magic weapons, but the existence of the Ethereal Stone is like an artifact, it is unavoidable, very rare, and it is a treasure among rare treasures." ”

"It is precisely because the ethereal spirit stone is extremely rare, there are very few space magic weapons, and it is different from the spar stone for refining the storage ring. Qiao Sanfeng added.

"Do you know where you can get the Ethereal Spirit Stone?" Feng Wuchen asked anxiously.

"I don't know. Gu Tongtian and the three elders all shook their heads.

"I don't know?" Feng Wuchen was suddenly disappointed, and the feeling of falling from heaven to hell in an instant.

Gu Tongtian said: "The old man of the ethereal stone has only heard of it, he has never seen it, and he has never heard of where to find the ethereal stone. ”

"Teacher, you can go and ask President Bai, he is a refiner and is more familiar with refining materials than us. Qiao Sanfeng said.

Feng Wuchen nodded, and immediately went to the Refiner Guild.

"President Bai!" Feng Wuchen flashed over, his face full of anxiety.

"I've seen Lord Feng!" Yang Qianxiao and other elders and the young master Yun Wuying saluted respectfully.

"Lord Feng, I don't know why I'm in such a hurry?" Seeing Feng Wuchen coming in a hurry, Bai Soul asked suspiciously, thinking that something big had happened.

"President Bai, do you know about the Ethereal Stone?" Feng Wuchen asked straight to the point.

"Ethereal Spirit Stone?" Bai Soul was surprised, and then said, "The Ethereal Spirit Stone Old Man does know that Lord Feng needs Ethereal Spirit Stone?"

"Well, does President Bai know where to find the Ethereal Stone?" asked Feng Wuchen.

"In the Celestial Tomb. "White Soul Dao.
