Not to mention how Nangong Yao, Shangguan Yu and others were going to formulate the rules of the Reverse Immortal Alliance, just saying that after Tu Tian was defeated by Duan Chen, the news gradually spread among some disciples in the outer palace, causing quite a stir.

And the forces such as Xuanmen who had been involved before also began to investigate Duan Chen's experience before joining the Beiyuan Immortal Palace.

When they learned that Duan Chen had defeated the Fake Dan Realm monks of the Nether Ghost Tiger Clan in a gambling battle on the main battlefield of the front line of the Great Wilderness Dynasty, Pang Jun and the other Fake Dan Realm monks couldn't help but be surprised.

After all, the Netherghost Tiger Clan is one of the most famous royal clans in the Demon Clan, even if Ji Lang, who was defeated by Duan Chen, is not the first person in the younger generation of the Netherworld Ghost Tiger Clan, but his strength is definitely the best in the realm of Fake Dan.

But now that even such characters have been defeated by Duan Chen, it is no wonder that Tu Tian will lose to the other party.

Duan Chen didn't know that because of his relationship with this move, Pang Jun and the others began to investigate his past experience.

At this time, he was concentrating on cultivating the Demon Immortal One Thought Method in his cave.

After all, he hadn't forgotten the fact that he now only had more than seventy years of life, although more than seventy years seemed like a long time, but if he couldn't step into the realm of Jindan earlier, Duan Chen always felt a little unsteady in his heart.

Therefore, during this period of time, he has been seizing the time to cultivate the Demon Immortal One Thought Method, and at the same time devoting part of his energy to cultivating the blood nerves and thousands of qi and blood techniques, striving to open up more qi and blood tricks, and prepare for the future impact on the Jindan realm.

However, in addition to cultivating, Duan Chen was also collecting information about the Tower of Babel, planning to find a time to break through.

After all, blindly burying one's head in penance is not a long-term solution, and occasionally he still has to go out to experience a battle, which is more conducive to his progress.

And judging from the information Duan Chen had collected during this time, breaking through the Heavenly Tower was not as simple as he had known beforehand.

First of all, although this tower seems to be open to anyone who can break into, in fact, this tower will only be open to the disciples of the outer palace on the first and fifteenth day of each month, and every time the disciples of the outer palace break through the heavenly tower, they need to pay a hundred medium-grade spirit stones, after all, every time this tower is opened, it needs to consume a lot of spiritual power.

Of course, with the wealth of the Beiyuan Immortal Palace, he is naturally not afraid of this consumption, and the reason why he is so stipulated is that he does not want the disciples of the outer palace to break through the Heavenly Tower indiscriminately.

In addition, the Heavenly Tower cannot use any spirit pets, as well as puppets and spirit runes, and some treasures that are extremely powerful and exceed their own cultivation and strength cannot be used either.

As for how to judge this, it is said that the spirit of the Tower of Babel has its own standards, and once someone violates this rule, they will be thrown out of the Tower of Babel directly, and as for the result of breaking through, it can only be regarded as a failure.

"I can't even think of using the spirit rune, yes, if you can use the spirit rune, even if you are a qi refining cultivator, I'm afraid you can break through the first layer of the Tower of Babel. Duan Chen thought so in his heart, and immediately left his cave mansion and flew towards the colorful auspicious clouds where the Tower of Babel was located.

Half an hour later.

Suspended above a colorful auspicious cloud in the center of the Beiyuan Mountain Range, a faint light flashed by, and a young man dressed in the green robe of the outer palace of the Beiyuan Immortal Palace was immediately revealed, it was Duan Chen who had just arrived here from Yunlai Peak.

At this point, the segment

Tatsu's figure was suspended in mid-air, staring at a nine-story golden tower in front of him with slightly squinted eyes.

This tower is about three or four hundred zhang high, as if a mountain peak is located on the auspicious clouds, the whole body flows with golden light, faintly exudes an invisible coercion, which is daunting.

At the bottom of the tower, you can vaguely see a crowd of people gathering, there are hundreds of people, many of them are pale, their breath is vain, as if they have tried to break through the heavenly tower, and failed on a certain floor.

Duan Chen saw this scene, paused for a moment in mid-air, and then his body turned into a ray of light again, shooting towards the direction of the Tower of Babel.

With Duan Chen's speed, it didn't take long for him to arrive in front of the Babel Tower, and at this time, he was able to see the true face of the Babel Tower, which was known as one of the three major cave heavenly spirit treasures of the Beiyuan Immortal Palace.

This tower is golden throughout, each floor is about thirty or forty zhang high, and there are many reliefs carved outside each layer of tower, and a large number of reliefs are connected together, as if telling a distant legend.

Duan Chen looked at it for a while, and then knew that the relief on the body of this Babel Tower told the story of the first palace master of the Beiyuan Immortal Palace who cultivated the Tao and became an immortal, and the so-called Babel Tower was the tower leading to the heavenly realm.

And the so-called heavenly realm actually refers to the immortal realm, which is another interface for monks to ascend to after becoming immortals.

Duan Chen didn't know what the so-called immortal realm looked like, and the relief on the Tower of Babel was not depicted, and the content depicted on the last relief was only the picture of the first palace master of the Beiyuan Immortal Palace who had survived the heavenly tribulation and ascended to the immortal realm.

Duan Chen looked at it for a while before retracting his gaze, and then began to scan the outer palace disciples gathered near the gate of the Tower of Babel, and then found Fan Xueyi, a disciple of Taishan Zhenren, in the crowd.

Beside Fan Xueyi, there are still several female disciples of the outer palace, their cultivation is high and low, the low ones are only in the middle stage of foundation building, and the high ones are the same as Fan Xueyi, they have all reached the realm of false pills.

However, whether it was the female disciple in the middle stage of foundation building or the female disciple in the False Dan realm, they all behaved very respectfully towards Fan Xueyi, and faintly looked like the leader.

Duan Chen's understanding of Fan Xueyi was limited to knowing that this woman was a disciple of Taishan Zhenren and was on an errand in the Xuanguang Palace, but he was not very clear about other aspects.

"The forces of the disciples of the outer palace are complicated, could it be that Senior Sister Fan has also joined a certain force in the outer palace?" Looking at Fan Xueyi, who was surrounded by a group of female cultivators in the center, Duan Chen secretly guessed in his heart, and then planned to pass by quietly and walk towards the tower gate on the first floor of the Tower of Babel.

As a result, Fan Xueyi seemed to have discovered Duan Chen's arrival a long time ago, and before Duan Chen passed by, she took the initiative to speak, and said with a smile: "Senior Brother Duan, you also came to break through the Heavenly Tower today?"

"It turned out to be Senior Sister Fan, yes, Senior Brother, I heard that the Tower of Babel is open to the Outer Palace today, so I wanted to come and have a good time. Duan Chen had to stop and talk to Fan Xueyi.

And the female disciples around Fan Xueyi took this opportunity to look at Duan Chen, but none of them recognized Duan Chen's origin.

However, some of these quick-witted people, thinking of Fan Xueyi's errand in the Xuanguang Palace, had already vaguely guessed that Duan Chen was most likely a disciple who had recently entered the palace, otherwise it would be unreasonable for Fan Xueyi to know the outer palace disciples, but they had never seen them before.

Fan Xueyi didn't seem to intend to introduce Duan Chen to others, but he was sure

After Ding Duan Chen came to break through the Heavenly Tower, he nodded slightly and said: "Since Senior Brother Duan, you are here to break through the Heavenly Tower, then Senior Sister I won't bother you, I hope you can make a good score in the Tower of Babel and strive to be on the Tongtian List." ”

"Thank you, Senior Sister Fan, for Ji Yan. Duan Chen clasped his fists at everyone slightly, and continued to walk towards the tower gate on the first floor of the Tower of Babel.

And not long after Duan Chen left, one of the Fake Dan Realm female cultivators couldn't help but whisper and asked, "Senior Sister Fan, aren't you going to introduce this little junior brother to us?"

"You don't know each other. Fan Xueyi shook her head, followed to look at Duan Chen's back, her beautiful eyes flashed slightly, and then moved away.

Seeing this, the other nuns did not ask any more questions.

On the other side, Duan Chen walked to the front and back of the tower gate on the first floor of the Tower of Babel, and immediately took out a hundred medium-grade spirit stones from the storage bracelet without saying a word, and handed them to the two Jindan monks who were in charge of guarding the tower door, and then stepped into the first floor of the Tower of Babel under the nod of one of the Jindan monks.

At the moment of passing through the first layer of the tower gate of the Tower of Babel, Duan Chen only felt a blur in front of him, and then he found that he had been moved to a ring with a length of 100 zhang and a width of 100 zhang, and then a golden light fell from the sky, enveloping Duan Chen, as if sensing Duan Chen's origin and identity.

The golden light comes and goes fast.

When the golden light dissipated, an incomparably indifferent old voice suddenly sounded out of thin air: "Outer Palace disciple Duan Chen, because you are the first time to break through the Tower of Babel, according to the rules, I have to remind you that there are a total of five levels on the first floor of the Tower of Babel, and only by passing the five levels of the Ministry can you be qualified to enter the second layer." ”

After a slight pause, the old voice continued: "In the first layer, for each level passed, ten sect contribution points will be rewarded, and if five levels are passed, in addition to fifty contribution points, you will also get an additional fifty contribution points. ”

"Thank you, Lord Machine, for your advice. Duan Chen nodded obediently.

In fact, Duan Chen had already inquired about what the Babel Tower Spirit said, and he also knew that the five levels on the first floor of the Babel Tower corresponded to the five realms of the early stage of foundation building, the middle stage of foundation building, the late stage of foundation building, the peak of foundation building, and the great perfection of foundation building.

Therefore, if you want to break through the first layer of the Tower of Babel, you only need to cultivate to the foundation building realm in the name, but in fact, you must have a strength comparable to the foundation building great perfection before you can hope to pass.

Of course, for Duan Chen, who has now cultivated to the realm of False Dan, it is not too difficult to pass the first layer of this Babel Tower, and the purpose of his coming here today is to challenge the opponent of the first level of the second layer.

Just when Duan Chen was thinking like this in his heart, on the ring where he was, countless spiritual lights converged from all directions, condensed into a vague figure, and finally completed the form.

This is a red flame Jin Biao with a long body and four legs with red flames.

At this moment, this Chiyan Jin Biao was looking at Duan Chen with a hideous expression, as if he might pounce on him at any time.

At this time, the voice of the Babel Tower Instrument Spirit suddenly sounded in Duan Chen's ears: "Kill it, and you can enter the next level." ”

Almost at the same time, the Chiyan Jin Biao let out a low roar from his mouth, and he rushed towards Duan Chen.
