The Heavenly Machine Tower has always been the most mysterious place in the world of the bitter sea. It is rumored that it was built by the Tianyan clan, and there is a cave in the inside, and between each Tianji Tower, there is a very mysterious space passage connected, and it is also rumored that it is built by the Tianji clan, a branch of the Shenji clan, which is not only a special place for collecting resources, but also a special building for transmitting information within the clan.

However, no matter what kind of rumors, it is undeniable that so far, no force or power has been able to find out the true origin of the Heavenly Machine Tower, and no one has ever seen the true owner of the Heavenly Machine Tower.

In the eyes of the world, every Heavenly Machine Tower in the world of the bitter sea is guarded by an extremely special and powerful puppet. Moreover, the Heavenly Machine Tower itself also has extremely special defense facilities, even the power of the Venerable cannot be broken, and the Heavenly Machine Tower has always been the most mysterious place in the world of the bitter sea.

Inside each Tianji Tower, there is a special independent space world, which is named Tianji Courtyard. The Tianji Courtyard is generally not open to the public, unless there is a particularly significant trading activity, or it is rented by some super powerful people or forces, it will be open to the public once or twice.

A Dandao event of this level is naturally a very important event, and the previous mansion master Situ Bofeng has met and negotiated with the tower master of Tianji Tower and rented the Tianji Courtyard, which makes the venue of this event able to be held in a mysterious place like the Tianji Courtyard.

In fact, whether it is in Xuantian or in the Bitter Sea World, the number of people who have really entered the Heavenly Machine Courtyard is absolutely extremely limited. And even those who have actually entered the Heavenly Machine Courtyard, basically no one can really describe what kind of place the Heavenly Machine Courtyard is.

In fact, after the news of this Dan Dao event, the reason why it was able to attract so many people to participate was not only because it was held by the first Dan Dao master who refined the Meritorious Saint Pill, but also because it was also related to the fact that he could have the opportunity to enter the Heavenly Machine Sect Elder Knowledge.

Thanks to the fact that the requirements of this Dan Dao event were not too high, some people who would not have had the opportunity to enter the Tianji Courtyard at all were lucky to enter the Tianji Courtyard this time to increase their knowledge.

Situ Bofeng, the owner of the Yuantong Holy Mansion, took advantage of the landlord, and because he had been in contact with Master Gutian several times, he became the agent of Master Gutian this time and the host of this Dandao event.

This was not the first time he had entered the Heavenly Machine Courtyard, but after entering the Heavenly Machine Courtyard of the Heavenly Machine Tower of the Yuantong Holy Mansion, his face still inevitably showed a look of amazement.

It's a room huge enough to shock anyone. In the entire room, only the four large metal pillars at the edges of the four sides served as supports, and there were no other supports to be seen.

The roof is a dome with a radius of 100,000 zhang made of extraterrestrial iron, and it is covered with it, so that the people standing in the room, no matter how high or low they cultivate, naturally and unnaturally produce a feeling of being as small as ants.

The real magic of this dome is not its size, but its special features.

I don't know where this material came from, but after being processed by special means, it has a power suppressive effect that is extremely terrifying for any immortal.

Whenever an immortal enters the area it covers, the mana in his body will immediately become dormant and unable to move slightly. Unless it echoes some of the corresponding formations laid out below, you can invoke your own mana.

In addition to this magical dome roof, there is another equally magical place in the Tianji Courtyard, that is, the red walls on all sides and the red floor tiles on the ground.

It is said that since the temple was unveiled to the world, no one has been able to recognize the material of the red walls and floor tiles.

At first glance, they look like red fairy jade, but in fact, they are not jade at all, and neither their texture nor their function can be possessed by jade at all.

Because, anyone who has entered the Tianji Courtyard knows that these red walls and floor tiles look like buildings, but in fact they are not simple buildings, they will undergo various changes as the Tianji Courtyard opens different functions.

Although the event has not yet begun, the red walls on all four sides and the red floor tiles on the ground have begun to automatically adjust to the most suitable shape according to the mode required by the Dandao event.

First of all, in the center of this room, there is a huge high platform ten feet high and one hundred feet wide. In the center of the high platform, there is a yin and yang fire pit with a circle of ten zhang and a strange shape, and there is a faint yin and yang flame aura that can reach the holy level in it.

This hand alone is enough to shock anyone.

After all, looking at the world of the Bitter Sea, there were really not many alchemists who could possess a saint-level flame. Even many Dan Saints may not have a saint-level flame in their hands, but in this most ordinary Heavenly Machine Courtyard, they can actually make a saint-level flame, and it is also a yin and yang flame, and there is more than one place.

In the Tianji Courtyard, in addition to the central platform, there are twelve smaller platforms on all sides of the platform, and the arrangement on them is the same as that on the central platform, with a strange yin and yang fire pit.

And outside the twelve high platforms on the periphery, there is a circle of bagua-shaped vacuum areas, on which are filled with futons, which must be prepared for the alchemists who are going to challenge the ancient heaven master this time.

Beyond the vacuum, there were rows of trapezoidal viewing platforms that stretched to the red wall, and by the time they reached the red wall, the height of the viewing platform had exceeded three hundred zhang.

On the viewing platform, it was even denser, and I don't know how many futons were placed.

At this time, Situ Bofeng and the eight peak Great Immortal Venerables and Tianzun who served as Wu Yan's guards stood on the central platform, all of them looking at this Heavenly Machine Courtyard with a look of amazement.

"Sure enough, it is a place created by the mysterious Tianyan Clan, it is so magical! The last time I entered the Tianji Courtyard in the Fallen Holy City, I was attending an auction event, and the layout inside was also magical and indescribable. Situ Bofeng said with emotion.

"Yes, the deity has also had the privilege of entering the Tianji Courtyard twice and participating in different grand events, and each time I see it, it is different, and its layout can also shock the deity every time. It's hard to imagine that in the world of the bitter sea, there would be such a divine creation technique. It's just that you said that this Tianji Tower was built by the Tianyan clan, but the deity didn't agree. The deity has been mentioned in some ancient texts that the Heavenly Machine Tower was built by the Shenji clan. ”

One of the Tianzun powerhouses also sighed, but he didn't think that the Tianji Tower was built by the Tianyan clan, but through what he had seen and heard before, he thought that it was a magical product left by the Shenji clan.

"Actually, if you think about it, you can understand that such a magical thing can indeed only be built by a magical ancient race such as the Divine Machine Race. Another Heavenly Venerable powerhouse echoed.

The eight people walked to the high platform, and according to the previous discussion, they found their own futon positions around the high platform, sat down cross-legged, and waited for Wu Yan's arrival.

This Tianji Courtyard is a very special place, and it is impossible for anyone to make ghosts here, so a few people don't have to bother to check the four sides. And Wu Yan, the main figure, did not come, and the gate of the Heavenly Rank Courtyard was not open to the public, whether it was the alchemists who participated in the Dan Dao Grand Event, or the viewers, they had not come here at this time, and in the entire Heavenly Machine Courtyard, except for the four puppet guards of the Heavenly Machine Tower and the nine people, there was no one else there.

After the nine people just sat down, they let out a sigh of emotion again, this time what they sighed was actually the futon under the seat, if this kind of thing was spread out, it was really unimaginable.

"I don't feel wrong, right? This is actually a futon woven with Heavenly Soul Immortal Grass? Obediently, this Heavenly Machine Tower is really a big deal, it can actually take out so many Heavenly Soul Immortal Grass futons?"

It is said that the Heavenly Soul Immortal Grass can play a role in calming the spirits of immortals in any realm, and it is the best auxiliary tool for cultivating and meditating. If it weren't for this Heavenly Machine Courtyard, I would have really wanted to get some of them!"

"Hahaha, Senior Feng is joking, right? Who can really take things away from this Heavenly Machine Courtyard, that is definitely a person who can make a sensation in the world of the Bitter Sea. I'm afraid that even a high-level Heavenly Venerable can't withstand the suppression of that dome roof, right?"

Several Great Immortal Venerables and Heavenly Venerables were talking a little half-jokingly. They didn't communicate with immortal thoughts. That dome also has the ability to cut off the communication between immortals and spirits.

This is also to guard against some dirty people, not to mention, this Heavenly Machine Tower is really worthy of being the most mysterious place in the world of the bitter sea.

While a few people were chatting, a red light gate floated up from the ground of the high platform without warning, and then floated a few feet away from the high platform.

Seeing this scene, the faces of the nine people moved slightly at the same time, and they all stood up.

With the experience of the nine of them, they naturally knew that the only person who could use this method in the Heavenly Machine Courtyard was undoubtedly the tower master of the Heavenly Machine Tower.

Situ Bofeng was even a little confused, and he didn't know why the tower owner of the White Machine Tower came here at this time. After all, according to the previous rules, the tower owner of the Heavenly Machine Tower would never appear on such an occasion.

However, the next moment, when the red light door opened, and Wu Yan's figure walked out of it and landed on the high platform, Situ Bofeng suddenly followed.

It turned out that it was not the tower master of the Heavenly Machine Tower who came, but he sent the Ancient Heavenly Master here.

"It seems that Master Gu Tian should have had a good conversation with the Lord of the Heavenly Machine Tower, and he was able to get the Lord of the Tower of Heavens to teleport here in person with this kind of Heavenly Machine Gate, instead of coming from there. ”

Wu Yan saw that it was Situ Bofeng, and then smiled and said: "It is indeed good to talk to the tower master in Xia, thanks to the tower master's high opinion, he passed this Heavenly Machine Gate teleportation method to Zaixia." ”

When the nine people heard this, they were stunned at first, and then they all showed incredible petrified expressions.
