The process of inviting Nigel was easier than Locke imagined.

This also shows from the side the current situation of resource depletion that the black domain is currently facing.

Also in the magic tower of Nigel, Rox simply took out the latest generation of black death virus developed by the Northland Witch Organization, and handed it over to Nigel for analysis and solution.

"Black death virus?" Seeing the lens in Locke's hand, Nigel looked astonished and surprised.

There is no need for Locke to introduce too much. With just a glance, Nigel can see the essence of this lens.

Later, at Nigel's invitation, Locke was able to enter the minus 38th floor of the magic tower deep into the ground and get a glimpse of its laboratory and collection room.

In addition to the magic tower hundreds of meters above the surface, Nigel also widened a considerable amount of space on the bottom of his magic tower.

With the perception of Locke's sixth-level knight, it is natural to find that the minus 38 floor is not the bottom layer of this magic tower, and there should be two floors below it.

However, with his courtesy to Nigel and the self-cultivation of a sixth-level knight, Locke did not randomly explore the other party's laboratory collection and other secrets.

The negative 38 layer is a huge virus library.

Here, Locke saw many other viral vectors besides the crystal carrier similar to the black death virus.

The vast majority of these viral vectors do not use crystals as their manifestations, but have various substances.

Locke even saw a frozen half-mermaid and half of a dragon's tail burning with a faint flame.

The half-mermaid is the product of the combination of the wizarding world and the mermaid family.

In the southern coastal zone of the Wizarding Continent, hunting and stealing against the mermaids has been repeatedly prohibited. The reason is the inherent beauty of the mermaid family, which really attracts a group of guys who pursue high profits to take risks.

Among them, there are many knights and magicians above the first level.

As for the half-burning dragon's tail, its source should be a third-level dragon.

Nigel can be collected here, not because of the value of the truncated dragon's tail itself, but Nigel used this dragon's tail as a carrier to cultivate a new type of virus specifically targeting dragon-type creatures

The virus database built by Nigel made Locke quite amazed.

It was also from Nigel that Locke got another piece of information. Sure enough, Nigel had a relatively complete inheritance of the Black Yao family.

And the death plague magic that he was proud of was initially studied by the handwritten notes of a fourth-level Black Yao tribe elder, and finally entered the room.

"That's what I gained in the ice field in the far north of the wizarding world. The Hei Yao clan was rejected and suppressed by other terrestrial races on the wizard continent. The ice field in the far north was their final resting place."

"But later, that part of the remaining Hei Yao clan should have been destroyed, and the ice and snow covered the traces of their haunts." Nigel shook his head and said.

The destruction of a demihuman race in the wizarding world in history didn't feel much for a sixth-level knight like Locke.

He just asked, "Do you have the ability to develop a new type of black death virus faster? Those native sea races in the Sea King Realm have amazing immune mechanisms."

"Of course, and my virus will be stronger." Nigel said with a purple diamond spar in his hand.

The black death virus is also stored in this purple spar.

However, it was not the original black death virus stored by the Sea Clan, but a new species developed by the four-level elders of the Hei Yao clan during the process of being squeezed out and suppressed by other terrestrial groups in the Wizarding World.

It is more powerful, spreads faster, and has a wider range of outbreaks.

What's more, a breakthrough is that the people who apply this black death virus are not just the sea race.

I don't know why back then, the four-level elder of the Black Yao clan didn't throw this virus on all the terrestrial creatures in the wizarding world.

In the end, it was Nigel who found the relics of the Hei Yao clan covered in ice and snow.

This black death virus, Nigel, will not be directly applied, after all, it is a product of tens of thousands of years ago.

Perhaps it was extremely advanced at the time, but in the eyes of Nigel, the sixth-level spellcaster at this time, it was nothing.

However, the effect of this purple diamond spar is to fundamentally update and modulate the Black Death virus.

With Nigel's personal abbot, and the wisdom of other top spellcasters in the wizarding world, the native creatures of the Sea King Realm, the sea clan, are about to usher in their nightmare.

Since Nigel’s magic tower left, Locke hasn’t rushed to Mamet’s

The alliance looked for Artes, but recognized the breath and direction, and flew towards the magic tower of the succubus Klenia.

Back then, the succubus Krenia and the corpse stitcher Rodman began to attack the fifth-level realm at the same time. Later, because of many affairs, Locke could not go to the end until the two old friends broke through.

Rodman has been promoted to Level 5 and has become a shining star on the Black Territory, second only to Nigel.

This guy, when it comes to the Sea King Realm, it's time to relive with him.

But Krenia failed to break through the fifth level.

Through the reports of some knights under his hand, Locke found that this fourth-level black magician has not only been low-key and silent in recent years, but also that the industries placed on Star Harbor are showing signs of ruin and closure.

Kleiniya's doing so is undoubtedly cutting her own money.

As a friend, Locke naturally has to show some concern for Krenya and see if he can help.

So just by the way, Locke flew towards Krenya’s magic tower residence

Compared with the ordinary and low-key of the sixth-level black magician Nigel's magic tower.

The magic tower of the fourth-level black magician Krenia can be called ruin and decay.

When Krenya was on another Blackland continent before, her magical Tulloch had also been there once or twice, which was definitely not what she saw before her.

How did you relocate to a new continent, but developed into this situation?

There was a bad feeling in Locke's heart.

Passing through a magical plantation overgrown with weeds, Locke's brows can't help but frown when he sees that the surrounding power level will not exceed the demigod element restriction.

But what's better is that although the elemental power level of the magic plantation is low, there is no trace of damage here.

It shows that even if Krenia has ushered in any changes, she should have received no invasion and bullying from outside.

Knocked on the door, and Locke stood at the bottom of the magic tower waiting for Krenya to open the door.

With his abilities, he can naturally break in easily and tear open the defense mechanism of this ruined magic tower like an ant.

But in the end he chose to knock on the door.

This is respect for friends.
