Xiling Chen accepted the ring that summoned the undead, not only the ring but also a skill book of the undead system.

This skill book is a skill book that comes with a summoning ring, and I heard from Purple Spirit Christina that as long as you can kill an undead summoner of the Lich level, you can burst something similar.

It's like a job transfer book, you need to fight a specific monster to explode.

And the Lich is the enemy that the undead summoner has to face.

Because of Xilingchen's own reasons, he doesn't have a specific occupation, so this skill book can be learned directly.

Skill Book: Servant Contract

Effect: After use, you can sign a contract with an undead creature.

Because the skill book does not have any attributes, Xilingchen can use it after learning.

After seeing Xiling Chen's study, Alyssa said: "I'll help you find a suitable undead to sign the contract in a while, even if you can't find a powerful one, you have to find a meat shield level, with us, as long as it is not higher than level fifty, you can successfully sign the contract." ”

"Thank you in advance." Xilingchen said.

After resting for more than ten minutes, the three of them continued to set off, and since they had arrived at the center of the sealing area, they continued to search for the source of the dark matter.

It can infect the undead of the level of the Great Lich, and it seems that the dark matter is more powerful than expected.

In addition to purifying the dark matter, this mission also has to try to rescue the two dragons infected by the dark matter, and the two dragons are currently missing, so they can only be found slowly.

However, the closer you get to the center, the more likely you are to encounter it, and the source of the dark matter may be in the center of the sealed area.

Sure enough, the closer you get to the central area, the dark matter will be richer, if it weren't for the protection of Xiling Chen's crystal ball, maybe it would have been eroded by the dark matter a long time ago.

At present, the dark matter of this level can control at least any creature below level 30.

A loud roar rang through the sky, and both Alyssa and Purple Spirit Christina stopped when they heard the scream.

It seems that this creature is not simple, and it can make dragons vigilant.

Ziling Christina closed her eyes and thought for dozens of seconds, then frowned and said, "I'm afraid it's not a giant beast, right?" Could it be that the space here can already allow the behemoth to pass through? ”

"Would you like to check it out?" Alyssa asked.

Xilingchen didn't know what was going on, so he didn't speak.

"You protect Lingchen, let's go and take a look."

In this way, the three of them decided to check the source of the cry, although they didn't know what the giant beast was, but they should be able to guess by listening to the name, it should be a very huge monster.

I must have seen the appearance of this monster in Xilingchen, and it was really huge!

It is more than three hundred meters tall, and his body is at least a thousand meters long, which is even more shocking than the three elders of the dragon clan before.

The giant beast was scarred and was currently resting in place, and not far away was the most unstable space in this sealed area, and a huge spatial crack was slowly closing.

It seems that this giant beast entered through this spatial rift.

And the source of the dark matter is also nearby, although I don't know what it is, Alyssa has already determined the direction.

There is no direct attack, as the Behemoth is not so easy to deal with.

The three of them observed for a while, and then Ziling Christina said: "This giant beast should have been forcibly passed through the spatial crack, and the injuries on its body were all cut by the unstable space, although attacking at this time is the best choice, but solving the dark matter is the key, we will go to clear the dark matter first, and then come back to deal with this giant beast." ”

"No problem!" Alyssa immediately left here with Xilingchen.

Towards the place where the dark matter is the most concentrated, Xiling Chen took out the crystal ball and purified it all the way, and he didn't know what the crystal ball was made of, and the dark matter absorbed was calmly stored inside.

The area shrouded in dark and dense dark matter is not very large, but the plants here are heavily eroded by the dark matter and are very aggressive.

There are no monsters there, though, and the surroundings are unusually quiet.

Smoothly, the three of them found the source of the dark matter, a severed human left arm.

Xiling Chen used the crystal ball to absorb the surrounding dark matter, and Ziling Christina carefully observed this arm beside her, and after observing it for a long time, she said lightly: "We seem to have found something terrible, the strength of the owner of this broken arm must be very strong, at least a strong person above level 100...... I guess it's at the level of a Guardian. ”

"Looks like I'm going to take this thing away...... Do you have a way to seal this left arm? At least keep the dark matter from proliferating. ”

Purple Spirit Christina immediately said, "I'll try, I'm not sure if I can succeed." ”

"Okay!"

After purifying the surrounding dark matter of the rich dark matter, Alyssa took Xiling Chen away from the left arm that emitted the dark matter.

If you want to seal an item of this level, you must use a strong force, and Xiling Chen probably can't bear it.

Ten minutes later, Alyssa returned to Ziling Christina with Xilingchen, she looked very weak, it should be that the consumption of the seal was very huge.

Seeing the two of them coming, Ziling Christina said weakly: "Lingchen, you can take it away." ”

Xiling Chen did not hesitate and directly put it into the space ring.

Now that the source has been found, this mission should be completed, but there are still many creatures in this area that have been eroded by dark matter, and it is very troublesome to solve it little by little.

Because Purple Spirit Christina consumed too much mana, she didn't attack the behemoth after dealing with the dark matter.

The three of them returned to the edge of the sealing area and told the Dragon Elder the results.

The source has been cleared, and there is no need for Xilingchen to come forward.

The three of them returned to the mechanical castle and waited for news from the dragon elders.

Two days later, a dragon infected with dark matter was sent over, Xiling Chen used a crystal ball to purify the dark matter in the dragon's body, fortunately, the dark matter infection did not last long, and this dragon member could recover after resting for a while.

Two giant dragons were infected by dark matter, and one was lost, presumably entering the spatial rift and leaving the Silver Dragon Continent.

After that, things were much simpler, the sealing area was completely lifted, there was no source, the dark matter in the air began to dissipate, and some ordinary creatures infected by the dark matter were purified by Xiling Chen using crystal balls.

The elders of the dragon clan strengthened the unstable space, and in this regard, the first mission was successfully completed.

On behalf of the dragon clan, Alyssa and Ziling Christina thanked Xilingchen for their help, originally wanting to stay with Xilingchen to play in the Silver Dragon Continent for a while, but who knew that there was a problem with the seal on the left arm that emitted dark matter, in order to prevent the dark matter from continuing to spread, Xilingchen decided that it was time to go back.
