Chapter 576: Door of Death

Sean's new residence is a 25-meter-high conical magic tower.

The magic tower has five floors, and each floor is very spacious.

There are three more floors underground. After Sean moved in, he expanded the underground space to five floors.

The builder of this magic tower is very skilled. There is even a small element reactor on the second underground floor.

The energy supply level of this small element reactor is naturally not as good as the element pool.

But in this plane battlefield front with relatively rough conditions, it is already extremely difficult.

More importantly, Sean can draw and convert some of the energy elements of other systems that he needs without spending too many energy crystals of various systems.

"We don't know what the final outcome of this plane war will be. Although I have been promoted to level 2, the overall strength of the Steel Wall Fist Knight Hall in this battlefield is slightly better than the native creatures of the Thunderfall World."

"But to be on the safe side, I'd better do some preparations in advance."

"It's also a way to verify the results of my previous summoning experiment."

At the bottom of the newly developed magic tower, Sean looked at the pile of magic materials he had just exchanged in front of him and whispered.

Many of these magic materials were exchanged by Sean after he arrived at the main base of the fortress. The currency used for exchange is naturally the task points earned by Sean in the past two years after he arrived at the battlefield of the Thunderfall World.

These task points can of course be exchanged for more hard currency magic coins, and many knights do this.

But Sean finally counted them and found that it was more cost-effective to directly exchange them for the various types of magic materials he needed.

The magic coin reserves of the Steel Wall Fist Knight Hall must be limited, but they can't resist the knights' unscrupulous exchange for magic coins, otherwise the Knight Hall itself will go bankrupt first.

Including the war gains and large amounts of war wealth obtained in the Thunderfall World War, they will also be transported back to the wizard world in the future.

Directly trade with the surrounding holy towers or business alliances in exchange for huge magic coins to "pay wages" to all knights.

This difference in exchange ratio is also to encourage knights not to directly exchange magic coins, but to exchange for higher-value resources of various systems.

Those knights will obviously also do this. As long as these materials are brought back to the wizard world in the future, the income earned will definitely be more than the current direct exchange of magic coins.

Not only the Steel Wall Fist Knight Hall does this, but also the Jade Flame Holy Tower, the Flame Sigh Holy Tower, the Light Flame Holy Tower, etc., all the holy towers and knight halls in the wizard world during the war will do this.

Many materials exchanged by Sean are placed in specific directions in various areas at the bottom of the magic tower.

A huge and extremely complex magic array diagram gradually took shape under Sean's handwriting.

Fortunately, before coming to the Thunderfall World, Sean collected and accumulated a lot of death magic materials during his travels.

Otherwise, relying only on the extremely rich thunder resources in the Thunderfall World, Sean might not be able to successfully build this "Death Gate".

...

"Is the war situation on your side very tense? Do you want me to give you my Dark Crystal Magic Wand first?" Lina asked with concern in the elemental light screen.

At this time, in front of Sean, in addition to the translucent elemental light screen, there was also a huge gray-white vortex.

The rich power of death rolled and gathered in this vortex.

Some indescribable sobs and murmurs echoed around, which were the whispers of the undead.

"No, I'm just taking precautions."

"If the situation really becomes more tense, I will ask you for help." Sean shook his head and said.

"I have made new progress in the research of inter-dimensional transmission channels during this period of time."

"Maybe it won't be long before we can meet again." Lina said with a smile on the other side of the elemental light screen.

…

Compared to a month ago, the power of death in Sean's magic tower is stronger.

Even the normal ground has now turned into a dark black.

Many knights passing by and patrolling feel a certain degree of depression when passing by Sean's magic tower.

More than half a month ago, Jeramy and the Reverse Feather Lion King came to Sean.

Took some magic potions and alchemy items from Sean.

This is their last visit to Sean recently. As the smell of gunpowder in the northeast becomes stronger and stronger, they are always ready to accept the command of the combat command to launch an attack, and they have no spare time to come to Sean again.

Ulysses, Sean's great-grandfather, did not come, except because he was busier and led a team of knights.

It is estimated that it is also related to Sean's previous confrontation with him and his refusal to marry the Ernst family.

It is worth mentioning that the female knight named Nataya has never actively disturbed Sean since she came to the Plain Fortress, perhaps because her self-esteem was hit by Sean's coldness.

But today, when Sean was checking the elemental restrictions around the magic tower, he accidentally saw Nataya standing in front of a material warehouse not far from his magic tower.

She was accompanied by a 15-man knight team.

Nataya's mission should be to patrol the nearby area, and her mission functions overlapped with Sean's.

After noticing Sean's gaze, Nataya turned around and left the place with a normal expression.

Sean saw this and just frowned slightly without saying anything.

"Move these elemental arrays 50 meters forward." Sean ordered several slave creatures around him, ranging from one to three meters in height.

These slave creatures were allocated to Sean by the fortress.

Originally, they could have given Sean more, and even planned to give Sean three first-level slaves.

After all, magicians are notoriously weak, and with these slave cannon fodders protecting them, Sean's safety can also be guaranteed.

However, Sean finally rejected the slave creatures provided by the fortress, and instead asked the fortress for the command of the other two small magic towers around.

Now, Sean controls the five magic towers around with absolute mental power.

Compared with those unreliable slave creature cannon fodders, Sean believes in his own strength more.

And the death gate on the bottom floor of the main magic tower has been built, and Sean can summon a large number of qualified cannon fodder from the undead world at any time.

Including, at this time, there are already a large number of undead creatures, which have been crowded in the two underground floors of Sean's magic tower.

The black ground that turned into rotten soil was the result of a large number of dead creatures gathering.

"This war should affect the situation and direction of the battlefield in the Thunderfall World, right?"

"I don't know if the fourth-level creatures will take action during this period." Sean said softly, facing the northeast.

At this time, a slight commotion came from not far away, and a large number of slave creatures lowered their heads with weak hands and feet.

It seemed that a third-level sky knight came to patrol.
