"I'm not sure for the moment, but I'll know if I have a chance to try."

"Do you remember anything?" Huang faintly asked with a little expectation and excitement, but the next words of Wu trace made him sad.

"No! I don't think of anything, but I feel good. " Cold no trace mouth wipe out a trace of smile back.

"Fart! Let's practice here by yourself. " I didn't get the ideal answer and didn't bother to pay attention to him, but the words revealed a trace of kindness.

Outside the dark pool, in a forest, the cold traceless figure appeared in it, surrounded by the strong energy of thunder attribute. In the condensation of mysterious fingerprints, blue lightning came out.

After repeated cultivation, Leng Wuchen's face has always been a little dignified. Lei's secret skill is not so easy to cultivate.

There is no day or night. Leng Wuhen usually goes back to the pool of the dead after several hours of cultivation, and then he will cross his knees to practice and stabilize his cultivation. With this stabilization, Leng Wuhen feels that his strength is not advancing but retreating. The level of cultivation seems to be slowly regressing with an imperceptible change.

This makes Leng Wuhen sweat. Leng Wuhen knows that it's not that his cultivation strength is really not advancing but retreating. On the contrary, he is making progress.

The reason for this change is that he broke through too fast, his aura was a little impetuous, and his cultivation was not fully consolidated. Now he has been consolidating his cultivation, and his cultivation strength is becoming more and more solid. It seems that he is going backward, but in fact there is no retreat.

Of course, it's just a slight change, but it's also frightening to Leng Wuchen. It doesn't look very impressive, but it's too late to save him if he's no higher in the future.

After all, the strength after the transformation is not stable, there is no solid solid, although I don't know what the real situation is, but I feel it must be very extraordinary, it seems that after the completion of the task, I will go back to the king's palace to test myself.

Otherwise, it's like a high-rise building. If there is a slight deviation in the main beam, it can't be seen at first, but if it is built to a high place, it will only become more and more crooked. We can imagine the situation at that time.

After ten hours of cultivation, Leng Wuhen will go to the forest again to practice hidden thunder. So time goes by slowly. Occasionally, Leng Wuhen will walk around.

As for the water dragon, it doesn't know where to go. When it's OK, it will come back to Leng Wuhen and make friends with him for a while. Leng Wuhen can't laugh or cry, but he doesn't care. As time goes on, Leng Wuhen likes this black ice dragon more and more.

It was about twenty days after that. In the woods, cold and traceless, the whole body was covered with a strong blue light, and the mysterious fingerprints in the hands were bearing.

At the same time, with the formation of fingerprints, the aura in the body is also in the rapid movement of meridians, which can be seen vaguely. The change of cold traceless fingerprints and the movement of aura in the body seem to be kept in the same rhythm.

In this way, not only is the requirement for the operation of aura extremely high, for the control of mind, it is more strict, a little error, it can not be prompted.

For a moment, a blue lightning appeared in the cold hands. The blue lightning trembled in the hands and seemed to be extremely unstable.

"Hiss

The blue lightning trembled for several times, then burst apart, and dissipated into energy in the air.

"Ah, it's really hard to practice the secret arts." Leng Wuchen smiles bitterly. Compared with Jue, it's more than ten times difficult to practice.

At this time, Leng Wuchen feels that he can use the shadow killing tactic easily. It's not ordinary to practice the hidden thunder skill and control the operation of aura.

I'm almost in a hurry. If it's not because I have enough spirit, I have a lot of help for my mind, it's even more difficult to cultivate.

But even so, it's almost 20 days of cultivation now, and I still can't smoothly push out the hidden thunder skill. Either the aura runs disorderly or the cooperation fails, which makes Leng Wuhen depressed.

As for the aura urge needed by this hidden thunder skill, Leng Wuchen only knew after practicing. If you urge the hidden thunder skill once, according to your own level, if you succeed, you can only use it three times at most.

It's still because of his strong aura. It would be great if ordinary people were only able to activate it once. There would not be one person who could activate the hidden thunder skill once if they were a thousand people with the same strength.

This kind of consumption is too huge. According to the information of the hidden thunder skill, if the practitioners of the same level make the last two hidden thunder skills, they will be exhausted.

Cold no trace now wry smile, if oneself urge concealed thunder Shu three times, only afraid is oneself first exhausted.

Of course, Leng Wuchen also knows that if he can transform all the spirit power of the spirit, it will be much easier to activate the hidden thunder skill at that time.

"Why, failed again?" The voice of desolation rings out in the cold and traceless brain."Yes." Cold no trace wry smile distant head, way: "thunder Department secret skill is really difficult to cultivate."

"You're pretty good. You look like you'll soon be able to practice successfully. You know, if people with spirit practice the secret skills of thunder, they can only look and sigh. Even if there are some people with good talent, they can't practice successfully in half a year. It's just how long you have been."

The desolation is slow.

"Go on." Leng Wuhen smiles and gathers his mysterious fingerprints again. No matter how difficult it is, there will never be any fear.

With the fingerprints coming out again, Leng Wuhen's aura is also mobilized in an instant. The majestic aura rushes rapidly in the meridians, and the aura needed to activate the Lei family's secret arts is also extremely huge. Even Leng Wuhen's aura is strong at the moment, he also feels the pain brought by the saturation of aura.

"This time, we must succeed." Cold no trace secretly clenches teeth, forbids the spirit, oneself all can cultivate successfully, this hidden thunder skill, oneself also certainly can cultivate successfully.

The mind controls the condensation of aura and fingerprints. Leng Wuchen's whole body breath is also surging. He is slightly calm. Leng Wuchen seems to have entered a wonderful state. He begins to condense the hidden thunder technique step by step, and a blue lightning in his hand condenses again.

"Cohesion."

The bottom of my heart a low drink, with a complex fingerprints suddenly a knot after a close, cold no trace around the body, ember gas surging out, and then gathered in the palm, the body's pores, now also has a trace of aura leakage.

But in the end, they are all controlled by an invisible force, just like a silk, gathering from all directions, and finally all of them are condensed together.
