Xia Fei realized that he owed Yizi and Qian Ying a lot, so he showed extra hard work, coupled with the mysterious and mysterious technique of "Heavenly Thunder Golden Bell Jue" that he had just cultivated, not only could a certain part become harder than iron, but also faintly had an electric current on it......

This crisp, this hemp, this sour!

Yizi and Qian Ying quickly begged for mercy.

Xia Fei let them be tired until they fell asleep, and then they looked and left.

Then, he went to Uchida Yuri to save for a while.

After surviving for a while, even if he was really beaten with iron, he couldn't help but feel a little weak, so he quickly took out two demon spirit blood bird's nests and made up for them, so that he didn't have weak legs.

He couldn't help but sigh and said, "In this way, I suddenly feel that the days of 'whipping out of reach' in the Brahma realm are actually quite good!"

……

After returning to the secret room of the retreat, Xia Fei asked the Great Sun Demon Bodhisattva to sort out the exercises looted from the Yin Yang Temple, and continued to contribute to the "One Thought Three Thousand Methods", while he himself continued to sort out the jade slips and scriptures that had not yet been cleared out in the space of the Zhenhu Tablet.

There are about tens of thousands of jade slips that have sunk to the ground of the lake in the Zhenhu stele.

Xia Fei wanted to use his divine sense to take out these jade slips, because the lake was really deep, and the underground undercurrent was turbulent, so it was still quite laborious.

So he simply drilled into the Zhenhu Monument as a whole, and when he salvaged the bottom of the lake, he also explored what was strange in the Zhenhu Monument by the way-it couldn't be that a lake was inexplicably sealed in the Zhenhu Monument, right?

After entering the space of the Zhenhu Monument, Xia Fei's first feeling was cold.

The blue lake water seemed to be melting the ice, and the temperature was terrifyingly low, Xia Fei tentatively touched it with his hand, and found that the temperature was definitely much lower than the cold storage where the ice was made.

But with such a low temperature, the lake water is not frozen, which is a bit too weird!

"Could it be that this lake water is not actually water, but some other liquid?" Xia Fei picked up a handful of water, urged the "discerning eye" of Buddhism, and watched carefully for a while, but did not find anything abnormal.

"It doesn't seem to be the problem of the water!, but there is something hidden in the water!" Xia Fei looked thoughtfully at the large deep and blue lake. Xindao: What is it that needs to be hidden with such a large lake?

But he didn't act rashly, the lake was so deep and wide that no one knew what was hidden inside. I threw the Yin Yang Palace's exercise jade slip into it before, and then took it out, and for a whole month, I didn't find any abnormalities.

But if you just rush into the water, no one knows what will happen.

He walked around the lake, trying to see if he could find any clues. After a long circle, I found almost nothing unusual except for the fact that there was often a red ant floating from the lake to the shore.

Xia Fei caught a red ant and put it in his hand, this red ant, the body is divided into three parts, namely the head, abdomen, and tail, the head and tail are dark red, but the middle abdomen shows a faint blue, which is somewhat similar to the lake.

"Could it be that these ants all went down to the lake to drink water?" Xia Feihu suspiciously took out a silver needle and pierced the ant's abdomen......

In an instant, a bone-chilling chill leaked out of the ant's abdomen, and at the same time, a light blue crystal the size of a grain of rice rolled out of the ant's abdomen.

Xia Fei couldn't help but be surprised, he thought it was a blue lake, but he didn't expect it to be a strange blue spar with cold ice.

He raised the spar in his hand and shone it in front of his eyes, and suddenly, a powerful attraction shot out of his eyes, and with a "whoosh", the blue spar was sucked into the depths of his pupils, and disappeared without a trace in the blink of an eye.

"Damn, what's going on?"

Xia Fei was dumbfounded, this fast crystal was actually absorbed by his pupils?

No, it was not absorbed by his pupils, but by the "Thunder Emperor Creation Divine Pupil" and the "Divine Heaven Netherworld Eye" parasitic in the depths of his pupils.

This sudden change made Xia Fei a little confused for a while.

After a long time, he reacted: "Could it be that this blue spar can actually be converted into the energy absorbed by those two supreme immortal treasures?"

That's right, it must be so!

He instantly became excited, because this is in line with the usefulness of these two magic weapons, when the Taiyi Dao Palace placed these two supreme immortal treasures in the eyes of the statue of "Taiyi Daozun", it was definitely not driven by the energy of the statue itself, but it continued to kill the eight hundred golden masters of the Nirvana Sect who killed the mountain gate - this is obviously illogical.

He originally thought that it might be an invincible master urging these two magic weapons, but after cultivating for a while, he realized that even the existence of the ninth grade peak of the Dao Gate and the peak of the tenth realm of the Buddha Gate would definitely not be able to continuously urge the "Thunder Emperor Creation Divine Pupil" and "Shenxiao Netherworld Law Eye" so many times in a row.

Therefore, these two immortal treasures must have another source of energy.

Now it seems that the source of this energy is most likely the blue crystals hidden beneath the lake. The reason why the people of Taiyi Dao Palace want to store a large lake in the Zhenhu Monument is probably because they want to hide this extremely precious resource. Otherwise, such a magic weapon, which is equivalent to the pinnacle of the ninth grade, is really a bit too wasteful just to hold the lake water.

If it's true, then the harvest is too great!

- Of course, all of this is just a hypothesis at the moment, and it needs to be further verified.

He grabbed a few red ants that floated up from the lake, took out the blue spar from their abdomen, and put it in front of his eyes, and sure enough, it was quickly absorbed by the "Thunder Emperor's Creation Divine Pupil" and the "Shenxiao Netherworld Eye".

"In that case, then I'll have to dive to the bottom of the lake to see how many blue spars there are!"

Although he was in high spirits, he did not carelessly jump directly into the lake, but entered the key space, urged the key space to slowly enter the water, and quietly searched the bottom of the lake.

As he dived deeper and deeper, the temperature around him became colder and the light darker and darker, but Xia Fei became more and more excited.

First, he could see that many ants with small blue crystals in his body were suspended in the lake water, like a pointing mark, guiding him in the direction of progress.

The second reason was that he felt that the activity of the "Thunder Emperor Creation Divine Pupil" and the "Divine Heaven Netherworld Magic Eye" in the depths of his eyes was getting higher and higher, and he couldn't wait.

This all means that he is getting closer and closer to the source of hedron energy.
