Eight Thousand One Hundred and Twenty-One Old Nest

Hearing what Tang Yu said, Chi Qiu's expression looked gloomy and scary. He clenched his fists and groaned angrily: "I didn't expect that I, Chi Qiu, would be deceived one day. Damn it, don't let me I’ll see you next time, or I’ll kill you.”

Chi Qiu raised his fist and roared at the bloody sky.

Unfortunately, the person who created that huge vortex should have left by now, so naturally no one will respond to him.

The other strong men in the Demon Refining City finally reacted at this time. Their faces were full of lingering fear. They raised their heads cautiously and looked at the sky, for fear that someone exuding a terrifying aura would appear again in the sky above their heads. huge vortex.

"Haicheng Lord, I would like to remind you that Cui Xiaoliang of the Cui family is not dead yet. The elder of the Cui family they are talking about is not sure what is going on now. If he is subdued by the master Cui Xiaoliang said, he will become him." One of his subordinates, the Demon Refining City may be in danger now."

Seeing that Hai Moxin also had a frightened expression and kept glancing at the sky, Tang Yu couldn't help but snorted coldly and said.

Hearing what Tang Yu said, Hai Moxin reacted, exclaimed, and said quickly: "Hurry back to the Demon Refining City. No matter what happens here, this mine has been almost destroyed anyway. Let's return to the Demon Refining City immediately. , don’t let others ruin your home.”

Hearing Sea Demon Xin's roar, the others also realized something, agreed with Sea Demon Xin's statement, and flew towards the Demon Refining City in unison.

However, these people were very self-aware before leaving. When they passed by Tang Yu and Chi Qiu, they all showed grateful expressions and thanked Tang Yu and the two.

Tang Yu waved his hands as if he didn't care. After sending these people away, Hai Moxin also said to Tang Yu: "Mr. Tang, do you want to go back to Demon Refining City with us now?"

"I'm more interested in this mineral vein. I want to explore it and see the insect spirit here instantly. What's going on? It should be fine!" Tang Yu asked deliberately with a smile on his lips.

"No problem, of course no problem." Hai Moxin waved his hands and said.

Not to mention that this mineral vein has been almost abandoned, it is said that Hai Moxin wants Tang Yu and his party to support him, and he has already done so.

Even now, Tang Yu has not returned to Demon Refining City with Hai Moxin. I believe that the senior officials of Demon Refining City would not dare to embarrass Hai Moxin again.

"Haiya, just follow Mr. Tang and take them to see those insect spirits." Hai Moxin reminded Haiya with a smile.

Tang Yu glanced at Sea Demon Heart calmly, with a half-smile expression on his face, and then flew towards the mineral vein.

"Haiya, lead the way!"

"Go directly to where the insect spirits are?" Haiya asked.

"That's right!" Tang Yu nodded and said.

Hai Moxin saw Tang Yu flying directly towards the depths of the mineral veins under the leadership of Haiya. He did not talk nonsense anymore, and chased the senior officials of Demon Refining City who had left. He left the veins and flew towards Demon Refining City. go.

What Tang Yu just said was not meant for Sea Demon Heart to hear alone. Other high-level officials in Demon Refining City also heard that Tang Yu was going to explore the insect spirit in this mineral vein.

If it were any other time, even if Tang Yu and Chi Qiu showed such strong strength, the senior officials of the Demon Refining City would probably not agree to Tang Yu's proposal, but now... no one dares to say no.

However, looking at the reactions of the senior officials of Demon Refining City, it can be seen that they actually have no objection.

"Haiya, can you give me a brief introduction to the situation of these insect spirits? I'm talking about situations that outsiders don't know." Tang Yu was flying to where the insect spirits were when Haiya took them. , made a request.

"Insect spirits are fake. They are spirit-patterned insects refined by others." Haiya said this to Tang Yu after pondering for a moment.

"What?" Tang Yu had a shocked look on his face when he heard Haiya's words, and asked quickly: "What's going on with this spirit-patterned insect?"

"Something similar to a puppet! It's just that these bugs don't have their own intelligence, and they are not very strong. They..."

"Wait a moment..."

Tang Yu frowned and reached out to stop Haiya's explanation. His mind turned a little. After thinking about something, he asked: "I heard that if those insect spirits are eliminated, there will be no evil crystal that can be refreshed." Come out, since these bugs are refined with spiritual patterns, where do these evil demon crystals come from?"

"I don't know either."

Haiya shook his head, with a wry smile on his face, and said: "I'm afraid no one in our Demon Refining City knows about this thing, let alone me. Otherwise, we wouldn't invest so many humans every time. corpses to feed these insect spirits. We only found out that these insect spirits can refresh the demonic crystal after devouring the corpses of living creatures.”

"Then have you checked, what are the functions of the spiritual patterns on these insect spirits?" Tang Yu suddenly thought of the crack space he discovered, so he asked calmly.

"Probably the function is transformation!" Haiya thought for a moment and said: "I suspect that the refreshed evil demon crystals actually devour the corpses of living creatures through these spirit-marked insects, and then use the energy in these corpses to It was further condensed and transformed into evil demon crystals, which were refreshed in these mines."

"Is that really the case?" Tang Yu looked at Haiya with a fierce look, and asked again: "Didn't you expect that these insect spirits really have such a fast transformation speed? I heard that after these insect spirits ate the corpse, it didn't take long for new evil magic crystals to refresh."

"This..."

Haiya was stunned when she heard Tang Yu's words, because she really hadn't thought about this matter.

To be precise, she hadn't thought about it at all.

Now hearing what Tang Yu said, Haiya kept thinking in her mind, and then blurted out: "Tang Yu, do you mean that these spirit pattern insects are just a mechanism to stimulate the refresh of evil magic crystals, and these evil magic crystals are transferred from other places?"

"Only this possibility." Tang Yu shrugged and couldn't help but look at Haiya, because he didn't expect that he just said such a few simple words, Haiya could actually guess so much, this girl is really extraordinary.

"Can you find the place where these evil crystals are refreshed? As long as you find it, even if this mine is abandoned, it won't have any impact!" Haiya said excitedly, and at the same time, her two beautiful big eyes stared at Tang Yu without blinking, as if she wanted Tang Yu to tell her where this place was.

Tang Yu immediately laughed and cried, looking at Haiya in a speechless manner, and then said:

"Haiya, why do you look at me with this expression? I haven't even come into contact with the insect spirits. How do I know if there is such a storage point for evil crystals? The inferences I made just now are just guesses. Even if you want to know something, you have to let me see the insect spirits before you can do it!"

Haiya immediately smiled stupidly and lowered her head embarrassedly, and realized her mistake.

Seeing Haiya's appearance, Tang Yu's face did not change, but layers of shock had already emerged in his heart. He was sure that his own guess should be correct.

These insect spirits indeed devoured the corpses of living creatures, and then transferred the absorbed energy to the crack space. They then transferred a certain amount of evil demon crystals from the crack space and stored them in the mineral vein space.
