The Mortal's Path to Immortality

Cao Rui closed his eyes and rested for a day in the Tianji Fortress.

After eliminating the fatigue of months of hard training and adjusting his mood.

He just started to erase the array runes that needed to be erased on the core array of the Tianji Fortress.

The way to erase them is naturally to use the weapon refining technique.

Cao Rui used the weapon refining technique, condensed the flame, and slowly melted the array runes on it.

Melted the rune imprint and smoothed the original position.

"This Tianjizi personally melted the array runes and it really didn't work."

"The material of this sphere is also extremely special and extremely difficult to melt."

Cao Rui can easily melt the flame condensed by the weapon refining technique of the first-level magic weapon, but at this moment, the speed of melting the runes on the sphere is not fast enough.

While smelting, Cao Rui looked at the magic array sphere with a diameter of ten feet, and smiled bitterly in his heart. This will be another long and hard journey.

......

Cao Rui smelted for a month in one breath.

Just now, the magic array of the entire control rune area was smelted.

At this time, although the magic arrays associated with more than a dozen levels were not completely erased, the part bordering the control rune had disappeared.

More than a dozen levels in the Tianji Fortress have been invalidated.

Because the [Control Rune] is invalid, the energy fluctuations of the entire sphere have disappeared.

The entire Tianji Fortress may have fallen into silence at this time.

After a short rest.

Cao Rui began to engrave the control rune.

It took Cao Rui several months to practice the [Control Rune] to perfection. It is a fusion of first-order runes and is quite complicated.

Cao Rui went through it carefully in his mind again and again.

It must be engraved in one go.

Cao Rui estimated his engraving speed again.

He came to a conclusion.

This time, it may take a month to engrave the [Control Rune] in one breath.

When Cao Rui practiced engraving this [Control Rune] exclusive to the Tianji Fortress this time, he made some changes to the [Control Rune].

First, it closed the energy output to more than ten levels.

Second, Cao Rui added a data template, and the controller of the Tianji Fortress can view the energy data of the fortress in real time.

The second is naturally to change the control permission to Cao Rui himself.

After making preparations, Cao Rui began to engrave the [Control Rune. ]

Fortunately, Cao Rui's consciousness was strong enough.

Such a complex rune could be engraved in one breath.

The rune of the magic circle on the sphere began to flicker.

Buzz.

As Cao Rui engraved, a faint energy fluctuation began to emanate from the sphere.

The surface of the sphere is the rune core of the Tianji Fortress, and the inside is the energy core of the Tianji Fortress.

Cao Rui had previously erased the control rune, and the energy core naturally lost its ability to absorb the energy of the world.

During Cao Rui's engraving process, energy absorption gradually reopened, and this energy response was generated.

As Cao Rui engraved, the energy response on the sphere became faster and faster.

Nearly a month later.

The whole sphere trembled, and the new [Control Rune] was engraved on the sphere!

As the [Control Rune] was activated.

At this time, Cao Rui's mind moved, and he saw the energy data of Tianji Fortress at this time.

[Energy value of Tianji Fortress]: 18% (growth rate 5%/year)

[Energy consumption of random transmission of ten states]: 10%

Simple and direct data allows Cao Rui to see the energy usage of Tianji Fortress more intuitively.

"Because all the levels are closed, some of the energy value has been restored."

"The Tianji Fortress is not for inheritance, so random teleportation naturally loses its meaning."

"When I am free, I have to change the random teleportation rune on the sphere, reduce the random function, and change it back to directional teleportation to meet the usage direction."

"Moreover, directional teleportation is a real teleportation type, a sixth-order rune, which is a higher level than the first-order teleportation rune I mastered before."

Directional teleportation is strong, and it can be teleported without a teleportation array.

But it is very difficult to use, and it requires a strong carrier as the basis for teleportation. For example, the Tianji Fortress itself is strong enough to perform directional teleportation.

Previously, the random teleportation of the Tianji Fortress was that Tianjizi made changes to several places on the directional teleportation rune, input the data of ten states, and performed random directional teleportation.

What Cao Rui has to do is to cancel the random function, restore the original appearance, obtain the data of the ten states, and master the directional transmission independently.

This is another huge project that can be seen with the naked eye. It is estimated that it will not be completed without a few years.

However, Cao Rui believes that if he can really complete the teleportation transformation project of the Tianji Fortress, the teleportation rune skills will be raised to a terrifying level.

After changing the [Control Rune] on the sphere, Cao Rui has now gained control of the Tianji Fortress.

At this time, Cao Rui can appear in the hall of the Tianji Fortress and any abandoned checkpoint room with a thought.

The data Cao Rui obtained is that all the checkpoint spaces and halls add up to a total of one thousand acres.

Add a space height of more than 100 meters.

The volume of the Tianji Fortress is indeed scary.

I don't know what method Tianjizi used to refine such a large Tianji Fortress.

Perhaps, the Tianji Fortress itself was transformed from a natural object?

Cao Rui can enter and exit the Tianji Fortress freely at this time.

When Cao Rui controlled the entire Tianji Fortress, he also discovered that there was a way to contact Tianji Baby in the core of Tianji Fortress.

After studying it, Cao Rui discovered.

This way of contact is to use the core sphere, a huge energy body, as an information radiation tool!

The information it transmits can cover the entire Qingqiong Realm across a distance!

Tianjizi used a highly penetrating 2nd-level communication rune to borrow the radiation ability of the sphere core to develop this function.

"Now that we have communication runes, we can save time on transformation."

"With this rune, it will be much easier to create a spiritual tool for the organization to communicate."

"Not only the communication ability, after understanding the directional transmission rune, you can even create tools to allow the organization's members to enter the Tianji Fortress for a gathering..."

"Make a hard puppet as a transmission carrier? Members only need to place their spiritual consciousness on the puppet to personally teleport to the Tianji Fortress..."

"The prerequisite for the 'gathering' is to master [directional transmission]."

"The most basic thing is to make the communication tool first, and try to pull the candidate you like into the organization."

"It is currently impossible to hold a real-life gathering, but a projection gathering can still be done."

Cao Rui flashed and reappeared on the side of the sphere in the core control room.
