After a while of running around, Yang Yu and the others finally returned to the fairy's palace. The fairy thanked them Lianlian and made a special trip to present garlands for them.

When he came to the palace, Kaka personally went on stage to deliver a speech and presented a medal to Yang Yu in recognition of his achievements.

The badge issued by the fairy is very small, only as big as Yang Yu's little finger's finger, and looks like a button.

This badge does not bring any attribute bonus, it is really just a very ordinary badge.

Although Yang Yu is pragmatic first, he doesn't hate being respected like this. He puts the badge on his chest as the elves ask.

"I really didn't expect that you actually successfully sealed the black bubbles. I'll stop talking nonsense."

After the commendation ceremony, Kaka immediately talked about solving the darkness underground.

"Next, I would like to deal with the source of darkness. After the processing is completed, I will give you a higher reward on behalf of all the fairies and send you safely back to the human world."

Staring at Kaka who was strikingly speaking, Yang Yu narrowed his eyes. From the words and phrases of the Fairy King, Yang Yu found that the attitude of the Fairy King became completely different from when he first saw it.

It seems to be getting colder.

After saying so many nice things before, why did they have no enthusiasm after successfully solving the black bubble?

Yang Yu was like a monk who was confused, but this did not prevent him from asking Kaka for rewards.

"I am happy to serve, Your Majesty. But before that, can I give me the racial essence of the fairy first? I need it to enhance my strength. If there is more strength, I can also provide more protection."

In addition to Kaka's attitude, Yang Yu also has some other doubts.

The task should be completed, but why the task on the panel is still showing in progress.

Could this fairy king be cheating? In fact, he has no racial essence at all. All this is just a lie he told, in order to make me willingly work for them in vain.

Thinking of this, Yang Yu narrowed his eyes.

There are many cases of NPC cheating, and these NPCs often turn into monsters, and after knocking them down, they can get real mission rewards.

If Kaka really wanted to cheat, Yang Yu would have been ready to slap it on the wall with a fly swatter.

"Don't look at me with the look of wanting to kill me.

You are right. After completing the mission, I should indeed give you the racial essence of the goblins, but it will take some time to get it out.

Now I am only one last step away from completely subduing the darkness, and I need to engage in a blitzkrieg. If you can completely solve the source of darkness, I will definitely present the essence of the goblins with both hands and send you home safely.

So please wait, and when you come back, I will hand over the things to you."

Kaka lowered her head and became extremely sincere.

Yang Yu just opened the panel to check the status of Kaka. There was nothing special about Kaka's panel, and everything was extremely normal.

He himself looked extremely healthy, and even removed the bandage on his hand, which seemed to have completely escaped the influence of black gas.

Is it really taking a lot of time to create racial essence? Don’t you want us to run away like the people we used to after getting racial essence?

After pondering for a moment, Yang Yu showed a confident smile on his lips.

"You fairies are so simple, I believe you once. But if you wait for me to return triumphantly and still get nothing, don't blame me for doing something rude."

"Don't worry, I will definitely prepare you for compensation. Next, it's time to talk about the work content..."

As he said this, Kaka asked Sisi to take out a huge scroll.

Sisi carried the scroll on her back and tried hard to slap her wings, and handed the scroll to Yang Yu.

Kaka smiled and said, "Just put this thing in the center of the deep underground, you can completely eliminate the darkness and everything will be happy."

Yang Yu opened the scroll and saw that the scroll was no different from the scroll Yang Yu and the others used just now.

When he handed it to Bai Jin, Bai Jin also told Yang Yu that there was no essential difference between the two scrolls, and even the main magic array was exactly the same, as if it was carved from the same mold. If it was not fully unfolded, there was no way to peek at the differences in details.

Yang Yu slowly rolled the scroll, threw it into the system, and said with a smile:

"Just do what you say, and you are waiting for my good news, just don't forget your promise."

"Don't worry, I am the king of fairies, keep my word and never break my word. Now, let's go to the entrance deep into the ground."

Flying away from the palace with shaking his wings, Kaka took Yang Yu and the others through the flower field and came to a cave entrance that was sealed layer by layer, all the way down. There were countless talismans stuck at the entrance of the cave, and there were subtle magic arrays on the talismans. The light of the magic array formed a golden bowl, which was pressed upside down at the entrance of the cave.

"Si Si, please explain to him."

After being called by Kaka, Sisi quickly explained:

"This is where the leak occurred in the past was sealed by us. As you can see, the black air that floated out here is extremely sparse and not strong, and even if we are around the cave entrance, it will not be affected at all. Thinking that this place may become a breakthrough in finding the truth, this cave entrance is thus preserved as one of the channels that may become a solution to the source of darkness underground.

We have begged humans to go down and find out countless times, but no one wants to go down after all."

Sisi became more and more disappointed as she spoke, but there was a little more heat in her eyes when she looked at Yang Yu. This was hope that had not been in front of him for a long time. Why didn’t he have expectations?

Kaka added: "But this cave is undoubtedly a must-pass way to the deeper underground. Don't worry, you have seen the principle of black gas. If there is no thing that can become a core, those black gas will not cause any storms, and it may be safer than you think."

"Is it safe?" Yang Yu raised his hand and wiped his chin. "It is not clear how these black gases are produced and what principle they are based on. We cannot determine the risks 100% of them, but I am willing to give it a try. Let me remind you again, what bets are used here. If we come back, we will not get the reward we deserve, and the consequences will be very serious."

"Don't worry! You will definitely not disappoint you."

After receiving Kaka's promise, Yang Yu led the team into the entrance without looking back.

It was a winding tunnel. It was clearly underground, but you could feel the wind blowing from the entrance of the cave. These winds had a little bit of black air, but it was not enough to affect Yang Yu and the others' minds. It was very safe.

Yang Yu walked into the entrance with Bai Jin and Oias carefully.

Kaka smiled and said goodbye to Yang Yu and the others, and then said to Sisi beside him: "They are really a group of amazing humans. They will definitely be able to solve everything smoothly. Sisi, now take me to the place where the kernel is stored, I want to see our corrupted compatriots now."

Sisi seemed a little hesitant, "But, Your Majesty the King, don't you send some people here to ensure their safety?"
