As long as the demonic energy in these demon cores is strong enough, Lin Fan might be able to reach an even more powerful level in a short period of time. Then, Lin Fan could help Qingshuang and the others kill these demons in one fell swoop.

In this way, it can be considered as revenge for Lin Fan.

After all, it was absolutely impossible for Lin Fan to ask others to help him take revenge. Moreover, if that were the case, it would seem that he would still owe Qingshuang and the others too much. Because, Lin Fan didn't know whether Qingshuang and the others would be willing to help him. No one could predict these things.

If you don't help.

Lin Fan would also feel guilty.

Therefore, Lin Fan decided that he still had to work hard to fight for it. If, under such circumstances, it still didn't work, then Lin Fan didn't know what to do. In short, Lin Fan was unwilling to give up these good things just like that.

Of course, Lin Fan also has his own plan. Since these demon cores cannot be made to disappear, then Lin Fan has to use his own method to break the protective shield. As long as the protective shield is broken, the demonic energy in the demon cores can naturally be absorbed, thereby improving Lin Fan's cultivation. Although this plan sounds very risky, after all, there are many demon cores here, all of which belong to demon kings. The cultivation of these demon cores is definitely not ordinary strong. If Lin Fan's cultivation absorbs these demon cores, I wonder if he can directly jump to a higher level?

This plan is also very risky. If it fails, Lin Fan's body will be eroded by these evil spirits. In that case, Lin Fan's cultivation level will definitely decline.

After all, this demonic energy was also the power of the Demon King. A Demon King's cultivation was incredibly powerful. Furthermore, this demon core was from a Demon King-level monster, so its demonic energy was undoubtedly incredibly strong. Therefore, Lin Fan had to take the risk. However, before attempting, he asked, "By the way, what material is the protective film on this demon core made of?"

"It's made of special materials from the demon race." At this time, Xiaobai answered in Lin Fan's mind.

"Special materials? Could it be the kind of materials that are rare and precious?" Lin Fan asked doubtfully.

"That's right, it's a treasure from heaven and earth!" Xiaobai nodded and said.

"Are these demon cores made from rare treasures?" Lin Fan asked again.

"No, it should be said that it was refined from a very rare treasure from heaven and earth, and the name of this treasure from heaven and earth is the Nine Nether Demon Flower!" Xiaobai said.

"What kind of rare treasure is the Nine Nether Demon Flower?" Lin Fan couldn't help but ask curiously after hearing this.

"The name of the Nine Nether Demon Flower means that it can make people develop demonic nature. Then, under the control of the demonic energy, people will lose their sanity and turn into killing machines. Finally, this demonic nature will be converted into its own energy. If you can devour the energy of the Nine Nether Demon Flower and absorb it, it will be of great help to you!" Xiaobai said.

"Oh, so that's how it is! Doesn't that mean my opportunity is also very great!" Lin Fan said quickly.

"Well, it's really big!" said Xiaobai.

"Haha, that's great!" Lin Fan laughed loudly, feeling very excited. After all, he was really satisfied with the result.

After all, with this opportunity.

Then the future battles will be much easier, and you can also get some benefits. However, Lin Fan still asked: "What kind of defense does this protective shield have?"

"I don't know about that either!" Xiaobai shook his head.

"Uh!" After hearing Xiaobai's answer, Lin Fan was speechless. After all, Lin Fan didn't know how to respond to such an answer, and this protective shield was still an unknown. Who knew what was inside.

However, at this time, Lin Fan couldn't say anything, otherwise it would affect Xiaobai's judgment, so Lin Fan had to endure it.

Next, Lin Fan began to study the protective shield. Although he really wanted to know what material it was made of, Xiaobai had apparently said it was made of special materials from the demon race. So, even if he asked, he wouldn't necessarily get the answer. After all, Xiaobai didn't know the origins of these materials either. And if that was the case, breaking it would be quite difficult.

However, Lin Fan was not discouraged. He believed that as long as he worked hard to find it, there was still hope. Moreover, Lin Fan believed that sooner or later, he would be able to break through this protective shield.

At this moment, Lin Fan also remembered Xiaobai's previous reminder. Didn't he say this was a city? If it was a city, there would definitely be people coming and going, and in a city, perhaps, one could find some powerful cultivators. So, Lin Fan said to Xiaobai, "Didn't you say there were powerful cultivators here? Tell me their information so I can find their location. Maybe I can find out if any of the cultivators here are among the more powerful ones?"

"Hehe, do you think it's possible?" Xiaobai said. Lin Fan did not refute this. It's not that Lin Fan didn't have the courage to look for it, but mainly because what Xiaobai said made sense. It was estimated that no one would dare to enter here. However, Lin Fan asked again: "Since no one can come in here casually, then, do you know where the way to the outside is?"

"Uh...!" Xiaobai hesitated for a moment after hearing this, but soon said, "I can tell you this, but you have to promise me that after you leave here, don't tell anyone that I told you all this!"
