A few days later, Chu Chen finished building and debugging the teleportation array, and after everything was done, he stepped on the teleportation array, teleported away, and when he reappeared, Chu Chen had already arrived in the Tianchen Sect, and returned to the Tianchen Sect, Chu Chen did not call everyone over, but dismantled the teleportation array, and it took a few days to transform this teleportation array, and transformed it into the same size as the teleportation array in the Infinite Mountain, so that so that so many people could be teleported at the same time.

After the debugging was completed, Chu Chen sent someone to call the four ancestors over.

In the Tianchen Hall, Chu Chen sat on the main seat, and the four ancestors below, Luo Sheng, Ke Yan, and Ke Yong, all came.

"Congratulations to the young master for his promotion to the Yuan Infant Realm!" As soon as the four big ones saw Chu Chen, they immediately clasped their fists and saluted, and said respectfully.

Hearing the words of the Four Great Ancestors, Luo Sheng and the others all cast shocked glances at Chu Chen one by one, although the Four Great Ancestors were calm on the surface, they were also extremely shocked in their hearts, because Chu Chen's cultivation speed was too fast, when they only saw Chu Chen, it was only the Jindan period, it was only the Jindan period, it was only a matter of time, and it was already the realm of the Yuan Infant, this kind of cultivation speed made them unreachable!

"I'll tell you something. Chu Chen smiled and said: "I found the inheritance classics left by the Boundless Sword Sect in the Wuliang Mountain, the demon head there has been eliminated by me, from now on, the Wuliang Mountain is also the place of my Tianchen Sect, the four ancestors, the aura there is only stronger than here, is not weak, do you want to discuss, send two people to bring some disciples over, and study the inheritance of the Wuliang Sword Sect well?"

"The inheritance of the Infinite Sword Sect?!" Hearing Chu Chen's words, the four great ancestors were shocked again, Chu Chen went to Wuliang Mountain, they knew, but they didn't expect that Chu Chen actually obtained the inheritance of the Infinite Sword Sect, the Infinite Sword Sect, back then, it was the existence of the Mighty Spirit Realm, there were few forces that could match it, and the inheritance of the Infinite Sword Sect was obtained, so in the future, Tianchen's strength will definitely go to the next level, now, Tianchen Sect lacks nothing, only time, as long as Tianchen Sect is given tens of hundreds of years, Tianchen Sect will definitely be able to dominate Cangling!

"Young master, I'll go with Brother Shangguan. Ouyang Xuan took the initiative to ask Ying, hoping to go over.

"It seems that our Tianchen Sect can be divided into several branches in the future, so let's bring people over first to get acquainted with it, and I will send a few more people over in a few days. Chu Chen said, as he spoke, with his right hand, the Infinite Sword Order appeared in his hand, and then directly threw it to Ouyang Xuandao: "This is the key to open the secret room, the secret room is hundreds of zhang below the cliff on the east side of the main peak, this sword order can help you find the secret room, I have connected the teleportation array here with the teleportation array of the Infinite Sword Sect, I wrote the teleportation method on the sword order, after you pass, it is best to copy all the classics and scrolls with jade slips, and it is best not to bring out the things in the secret room, so as not to lose them." ”

"Yes, young master, we're going now!" Ouyang Xuan took the Boundless Sword Order, took Shangguan Ling and a few disciples and turned around and walked out of the main hall, heading to Boundless Mountain through the teleportation array.

After Ouyang Xuan and the others left, Chu Chen began to ask about the cultivation of those children, and everyone replied that they were all not bad, they were quite hardworking, and there were very high-level existences among the disciples brought by each person.

"During this time, I will stay in Tianchen Sect and give you an hour's pill class every day, don't you really want to learn to refine pills, I will meet your requirements, from now on, you will refine the pills of each peak by yourself, I don't care." Chu Chen said.

"Big brother, don't worry, as long as you are willing to teach us the Dan Dao, we will definitely learn it well, and we will never let you down!" Yun Kun couldn't help but say excitedly, and the others also showed excited expressions one by one, they had wanted to learn the art of alchemy from Chu Chen for a long time, and today, their dream was finally coming true.

"Don't be too happy, Dan is a way, broad and profound, you must rely on the accumulation of time to become an alchemy master, the so-called master leads the door, the cultivation is personal, whether you can achieve something, it depends on your own. Chu Chen smiled faintly.

From this day on, Chu Chen has not left the Tianchen Sect for the time being, one is to pass on the alchemy techniques of Luo Sheng and Yun Kun, and the other is to collect the materials for the construction of that formation, the collection of these materials is not an overnight thing, although there are many materials in the Void Secret Realm, but there are still many materials that are not in the Void Secret Realm, not to mention, this large array he built is not an ordinary large array!

After staying in the Tianchen Sect for three days, Chu Chen asked Luo Sheng to go to Tianyuan Valley and asked him to call the three brothers from the Sect over.

"Meet the master!" After the three brothers of the Lizong saw Chu Chen, they greeted each other very respectfully.

"Leaving the sect, Wuliang Mountain is now a part of my Tianchen Sect, where there are many inheritances handed down from the Wuliang Sword Sect, you have a good understanding in the past, and you will pass it on to your disciples in the future. Chu Chen instructed the three of them.

"It's the master, we will definitely not let the master down!" Hearing Chu Chen's words, the gentleman was slightly stunned, and then hurriedly replied respectfully, Infinite Sword Sect, that is the existence that dominated the Cangling Realm in the past, and being able to cultivate its inheritance technique is simply a great creation, they will definitely cultivate well!

"Let's go. Chu Chen nodded with satisfaction, and then personally sent the three of them to the teleportation array and sent them over.

The three brothers of the Lizong have quite an understanding of the way of the sword, and Chu Chen naturally hopes that the three brothers can learn the essence of the Infinite Sword Sect inheritance, but how much they can comprehend depends on themselves in the end.

After about three months, Nangong Old Ancestor came over and told Chu Chen that all the materials he needed had been gathered.

Chu Chen came to the warehouse, only to see that there were many materials on the shelves, all of which Chu Chen needed, and the materials on the list he gave to Nangong Ancestor were all here, Chu Chen counted the materials, and after confirming that they were correct, he waved his hand and put all the materials into the storage ring.

"I'll leave the matter here to you and Ancestor Ximen, and I'm going to leave for a while. After Chu Chen received the materials, he said to Nangong Old Ancestor.

"Don't worry, young master. Nangong Old Ancestor replied respectfully.

Chu Chen left the Tianchen Sect with the materials, and he teleported all the way to the Ethereal Secret Realm in the sky of Nanzhou through the teleportation array, and along the way, he collected the other materials in the Ethereal Secret Realm.

On the square of the main hall, Chu Chen took out the materials he needed and placed them in front of him, and then divided them into categories, and after everything was ready, Chu Chen began to refine it.

With the passage of time, pieces of things of different shapes were refined by Chu Chen, and after refining, Chu Chen carved complex formation patterns on these things, and carved a formation pattern, which required Chu Chen to keep carving for a whole day at first.
