After a brief moment of shocked silence, Gu Yuan looked at Wu Dao and asked, "Is there no other solution now?"

Facing Gu Yuan's question, Wu Dao shook his head helplessly: "This is a method left by the ancient emperor. How can I have a solution?"

"If my main body had reached its peak, I would have a way to solve this problem. Unfortunately..."

As he said this, he glanced at the old Taoist priest, making the old Taoist priest feel inexplicably embarrassed.

After all, his original body in his previous life was a very terrifying existence. He was also an emperor who stood at the pinnacle of the universe.

As a result, in order to break through to a higher realm, or perhaps to become an ancient emperor, he cut off everything and began reincarnation.

The result is what it is now.

Wudao's words hit everyone hard, making them feel helpless and aggrieved.

But soon Gu Yuan, Wudao, the old Taoist priest and others all looked at Lu Fan.

They really had no solution, but Lu Fan might not be so sure.

After all, the barrier just now was so terrifying, but it was easily broken by Lu Fan.

Wu Dao pondered for a moment and said, "My Lord, your portal magic weapon is not an ordinary thing. Perhaps we can use it to pass through these independent spaces."

In fact, even if Wudao didn’t say it, Lu Fan had thought of this.

After all, the Tianji Portal can teleport across space, so there is no problem with that.

However, the Heavenly Secret Teleportation Portal is not omnipotent, and it may be able to cross one or two spaces.

However, it is not known whether it is possible to successfully cross hundreds or thousands of independent spaces at one time.

After all, he hasn't tried it himself, and he won't know whether he can succeed until he tries.

Under the gaze of everyone, Lu Fan took a deep breath and nodded: "Let's try it first."

As he said this, he summoned the Tianji Teleportation Portal without hesitation, and then tried to open the Tianji Teleportation Portal, and determined the teleportation location in front of the small tiankeng.

However, it failed the first time it was activated and was simply unable to teleport to such a long distance.

After all, there are hundreds of independent spaces in between.

This is equivalent to the Tianji portal having to cross hundreds of independent spaces at one time, which is obviously extremely difficult.

If it were really that easy to get through, then the ancient emperor wouldn't be anything to be afraid of.

Lu Fan and others were not surprised by this result.

After calming down, Lu Fan immediately set the teleportation location behind one hundred independent spaces.

However, after passing through one hundred independent spaces, the activation still failed.

Lu Fan was not discouraged and continued to try to pass through fifty independent spaces and thirty independent spaces.

But without exception, all such attempts failed.

The Tianji portal simply cannot pass through so many independent spaces at the same time.

After so many consecutive failures, Lu Fan frowned and felt a little helpless.

The ancient emperor was indeed extraordinary. He had arranged these methods many years ago to stop all of his people here.

You should know that the Tianji Portal rarely encounters such obstacles. Even if there are obstacles, you can easily pass through them after upgrading.

But now it is failing one after another.

You should know that the current Tianji portal has been upgraded many times by myself.

After a brief moment of helplessness, Lu Fan took a deep breath, and a determined look of disbelief flashed in his eyes.

He really didn't believe that the Tianji portal couldn't even pass through several independent spaces.

With this idea in mind, he continued to experiment.

Starting from fifteen independent spaces, fourteen independent spaces, thirteen independent spaces, twelve independent spaces...

In this way, Lu Fan tried again and again.

Gu Yuan, Wudao, the old Taoist priest and others stared at Lu Fan without blinking, waiting for Lu Fan to bring good news.

After trying four independent spaces like this, the Tianji portal was finally successfully opened.

Looking at the successfully opened Heavenly Secret Transmission Portal, Lu Fan was stunned for a moment, and then an expression of excitement and ecstasy that was difficult to conceal emerged on his face.

"Success!"

The old Taoist priest, Gu Yuan, Wudao Tonglun and the other three were also quite excited when they saw this scene.

After all, this is a space barrier set up by the ancient emperor. Being able to pass through a space is already very good.

At this moment, the Tianji portal could pass through four independent spaces at once, which completely exceeded their expectations.

If there were no Heavenly Secret Transmission Portal, even Gu Yuan and Wu Dao would be helpless.

After all, they are just the spiritual clones of the original body, not the original body itself.

Therefore, even though they are very powerful now, they are simply unable to overcome the arrangements left by the Void Emperor.

Fortunately, Lu Fan's attempt was successful.

After a brief moment of excitement, Lu Fan took a deep breath, looked at everyone and smiled:

"It's not enough to cross four independent spaces at once..."

After saying this with a smile, he took a deep breath and asked in his heart: "System, how many points does it cost to upgrade the Heavenly Secret Portal twice?"

Although upgrading the Tianji Portal had cost him a lot of points, he didn't feel any pain at the moment.

After all, no matter how many points you spend, as long as you can keep upgrading the Tianji portal, it will be completely worth it for you.

After all, the Tianji Portal can not only be used to travel, but also as a treasure for escape.

For the time being, I may not need to use the Tianji portal to escape, but that may not be the case in the future.

When he goes to the Middle Thousand World or even the Great Thousand World, he will definitely encounter powerful and terrifying beings whom he will not be able to resist.

At that time, the importance of the Heavenly Secret Portal was revealed.

Therefore, the points you spend now are nothing, and you can earn them back ten or a hundred times in the future.

[Ding, upgrading the Heavenly Secret Portal twice requires 800 billion points. ]

Hearing the answer given by the system, Lu Fan was stunned for a moment. This number surprised him a little.

However, considering that the upgrade not long ago cost a full 300 billion points, it seems normal to spend 800 billion points to upgrade twice at this time.

Thinking of this, he took a deep breath and said without hesitation: "System, upgrade the Heavenly Secret Transmission Gate twice."

Anyway, I can earn back double the points I spent now, so it’s no big deal.

Moreover, since the Void Emperor took great pains to arrange this place, it shows that the opportunities and fortune here are definitely not simple.

If you can get the opportunity and fortune here, it will definitely be much more important than 800 billion points.

As he finished speaking, a reminder sound rang in his mind.

[Ding, the Tianji portal begins to upgrade, and 800 billion points are automatically deducted. ]

As the prompt sounded, the Tianji portal suddenly burst into a dazzling divine light.

At the same time, Lu Fan and others clearly saw that the dense runes on the surface of the Tianji portal began to merge and reorganize, and a new type of runes appeared.

Compared to the previous runes, the runes that reappeared at this moment were more mysterious, and the aura they exuded made people feel awe from the bottom of their hearts.

In addition, other very obvious changes have occurred in the Tianji Portal.

In this way, under the watchful eyes of Lu Fan and others, the Tianji portal continued to change.

This change lasted for a whole stick of incense, which was longer than any previous upgrade.

However, Lu Fan and others were not in a hurry, but seemed extremely expectant.

Especially Lu Fan himself.

After all, this time he upgraded the Tianji Portal twice in a row, spending a full 800 billion points.

The points spent on this upgrade were much more than the total points he spent on upgrading the Tianji Portal before.

Therefore, he was extremely looking forward to what kind of surprises the upgrade of the Tianji Portal would bring him.

He also wanted to know how many independent spaces the Tianji portal could pass through after the upgrade.

Of course, he didn't expect to be able to cross all independent spaces immediately after this upgrade.

He knew that was definitely unrealistic.

Looking at the upgraded Tianji portal, Lu Fan took a deep breath and immediately began to activate it.

At this moment, he wanted to see how many independent spaces the Tianji Portal could cross after being upgraded twice in a row.

As energy was injected into it, the Tianji portal was instantly activated, and Lu Fan began to try to see how many independent spaces he could cross.

The tenth, the fifteenth, the twentieth...

As one independent space after another was crossed, an extremely excited smile suddenly appeared on Lu Fan's face.

After a moment, the transmission limit test of the Tianji portal came out.

The fiftieth independent space.

After two consecutive upgrades, the Tianji Portal can actually penetrate fifty independent spaces at a time.

This made Lu Fan burst out laughing, and he told the old Taoist priest, Gu Yuan, and Wudao Tonglun, who were all expecting the result.

After hearing this answer, several people were shocked and excited.

Although these spaces that can be traversed are all divided into independent small spaces, they are not real big worlds.

But even so, it is enough to defy the will of heaven.

After a brief moment of excitement, Lu Fan looked at the old Taoist priest and the others and laughed out loud:

"Okay, let's get started."

Although reaching the small tiankeng within tens of thousands of meters requires crossing hundreds or even thousands of independent small spaces.

But now with a portal that spans fifty independent spaces, their speed will be greatly increased.

As soon as he finished speaking, Lu Fan and his group entered the Tianji portal one after another and disappeared.

Then the 50th independent space appeared in front, completely leaving the previous area.

Lu Fan did not stop and continued to open the Tianji portal for transmission.

Next, Lu Fan led everyone to continuously open the Tianji portal for teleportation, crossing the densely packed independent space.

After teleporting eighteen times in a row, they finally arrived at a place a hundred meters away from the small tiankeng.

There was no independent space within this distance, so Lu Fan put away the Tianji portal with confidence.

Although the small tiankeng was very close, Lu Fan and his group did not act carelessly.

After all, this is the arrangement left by the Void Emperor, who knows if there are other traps.

After all, the Void Emperor controls the power of space, so he may have left behind any fatal moves.

Just in case, Lu Fan hesitated for a moment and turned on the 100 billion points detection function again...
