Chapter 316 Controlling the Fortress of Heavenly Secrets

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

After eliminating the fatigue of eight 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.

Melt the rune imprint and smoothed the original position.

"The array runes melted by Tianjizi himself are indeed extraordinary."

"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 third-level magic weapon, but the speed of melting the runes on the sphere is not fast at this moment.

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

......

Cao Rui melted for three months in one breath.

Just now, the entire array controlling the rune area was melted.

Although the associated arrays of more than 30 levels have not been completely erased, the part bordering the control rune has disappeared.

More than 30 levels in the Tianji Fortress have been invalidated.

The energy fluctuations of the entire sphere have disappeared because of the invalidation of the [Control Rune].

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

After a short rest.

Cao Rui began to engrave the control rune.

This [Control Rune] that he spent eight months practicing to the perfect state is a fusion of three fifth-level runes and is quite complicated.

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

It must be engraved successfully at one time.

Cao Rui estimated his engraving speed again.

Draw a conclusion.

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

When Cao Rui practiced engraving this exclusive [Control Rune] of the Tianji Fortress this time, he made a slight change to the [Control Rune].

First, he closed the energy output interface for more than 30 levels.

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

Thirdly, of course, the control permission is changed to Cao Rui himself.

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

Fortunately, Cao Rui's consciousness is strong enough.

Such a complex rune can also be engraved in one breath.

The array rune 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 Tianji Fortress, and its interior is the energy core of Tianji Fortress.

Previously, Cao Rui erased the control rune, and the energy core naturally lost the ability to absorb external energy.

During Cao Rui's engraving process, the absorption of energy gradually reopened, and this energy reaction occurred.

As Cao Rui engraved, the energy reaction 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!

With the activation of the [Control Rune].

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 teleportation of thirteen 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 in my hands for inheritance, so random teleportation naturally loses its meaning."

"When I have free time, I have to change the rune of random teleportation on the sphere, reduce the random function, and change it back to directional teleportation to meet my use direction."

"Moreover, directional teleportation is a real sixth-order rune of teleportation type, which is a higher level than the fifth-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 requires a strong carrier as the basis for teleportation. For example, Tianji Fortress itself is strong enough to perform directional teleportation.

The previous random teleportation of Tianji Fortress was that Tianjizi made changes to the runes of directional teleportation in several places, input the data of Thirteen States, and carried out random directional teleportation.

What Cao Rui had to do was to cancel the random function, restore the original appearance, obtain the data of Thirteen States, and master the directional teleportation independently.

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

However, Cao Rui believed that if he could really complete the teleportation transformation project of Tianji Fortress, his teleportation rune skills would be raised to a terrifying level.

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

At this time, Cao Rui's mind moved, and he could appear in the hall of Tianji Fortress and any abandoned checkpoint room.

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

Add the space height of 800 meters.

The size of Tianji Fortress is indeed terrifying.

I don’t know what means Tianjizi used to refine such a large Tianji Fortress.

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

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

At the same time, after controlling the entire Tianji Fortress, Cao Rui also discovered that there was actually the contact information of Tianji Baby in the core of Tianji Fortress.

After some research, Cao Rui discovered.

This method of contact uses the core sphere, a huge energy body, as an information radiation tool!

The information it emits can cover the entire Blue Vault Realm!

Tianjizi developed these functions by using a fifth-level communication rune with extremely strong penetrating power and borrowing the radiation ability of the core of the ball.

"The ready-made communication runes save me time in modifying them."

"It will be much easier to create an organization's liaison spiritual weapon with such runes."

"Not only the communication ability, after understanding the directional teleportation rune, I can even make tools so that people from the organization can enter the Tianji Fortress assembly..."

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

"The prerequisite for 'assembly' is that I master [directional teleportation]."

"The most basic thing is to make a communication tool first, and try to attract the candidates I like into the organization."

"It is currently impossible to hold in-person gatherings, but projection gatherings can still be done."

Cao Rui dodged and reappeared on the side of the ball in the core control room.
