"Red Shadow …" "You!"

Seeing that Chu Fei was about to escape crazily, Hong Ying immediately raised his hand and said, "Look, the speed at which the spirit seed is absorbing the lightning energy has decreased. You shouldn't get distracted.

"I will settle this score with you later!"

Chu Fei also felt that the rate at which the spirit seed was absorbing had slowed down, so he rolled his eyes at the red figure and started to absorb it seriously. But he stayed in the lightning array for two hours, and slowly … He felt the power of thunder become increasingly weaker. Even the rumbling thunder beside his ears became weaker, as if it had completely vanished.

Weird, what's going on?

Chu Fei slowly opened his eyes, but upon opening his eyes, he realized that the hundreds of lightning in the valley had turned into seven or eight rays of dim light. If Chu Fei continued to absorb the energy, the seven to eight bolts of lightning might disappear along with him.

It had to be known that the lightning array was different from the fire array. The lightning array was first set up by Innate Rankers, and they had to trap the lightning in the lightning array for a long time in order to have such a strong power. Now that it had been completely consumed by Chu Fei, they could only wait for the next thunderstorm to arrive before they could start storing it again …

"It looks like... I really can't stay here any longer. Forget it, let's go to the twelfth level of difficulty. "

Thinking about that, Chu Fei calmed himself down. Looking at the spirit seed's appearance, it was obvious that it had not absorbed to the limit, since it was proven that the power of lightning could promote the growth of the spirit seed, how could he give up on such a good opportunity? Although Chu Fei knew that it was a bit immoral for him to completely absorb all of the lightning energy that was at the eleventh level of difficulty, he could still store more lightning energy and there were not many people who would come with lightning array.

"Chu Fei, what's wrong? Should I take a break? "

Seeing Chu Fei coming out from the lightning array, the Elder Zhao immediately welcomed him. This time, the time was extremely short, only two hours was needed, that was normal. With the difficulty of the lightning array for eleven days, for Chu Fei to stay inside for two hours was already very good. Seeing Chu Fei's normal performance, Elder Zhao actually felt comfortable from not coming here for a long time. Was this the performance that a normal disciple should have?

"Elder Zhao, I entered the eleventh level of difficulty today. If I want to enter the twelfth level, would that still be okay?"

"Eh? "What?"

After all, he hadn't seen anyone who wanted to challenge the twelfth level of difficulty in a long time. Even Dongfang Yu, who was heavily injured during the last challenge, hadn't challenged him again after a month, "Chu Fei, you don't want to challenge the twelfth level of difficulty, right?"

"Yes, Elder Zhao, please do me a favor."

Level 12 difficulty … ….

Although he knew that Chu Fei had always been strong, and had even defeated Su Baixiao, so his rank was at least third, but compared to Dongfang Yu, he still had a gap in rankings. And with this difficulty of level twelve, even the experts at the peak of the third level of Pulse Condensation Period were unable to withstand it.

"Chu Fei, you must think this through clearly. Even a warrior at the peak of the third level of Pulse Condensation Period cannot handle the twelfth level of difficulty, and the moment you enter, the lightning energy will not be controlled by the formation at all. If you are injured inside, I might not even be able to save you from death …"

The Elder Zhao was truly concerned for Chu Fei's safety. As the current famous genius of the Mysterious Sky Academy, he did not want Chu Fei to die like this in the lightning array, it would be too tragic.

Seven Killing Arrays, other than the lightning array, the other six formations could be controlled by array formations. If anything was amiss, he could forcefully stop the operation of the array, but the lightning array was different, the lightning energy inside was all forcefully stored inside, the lightning energy was not controlled by the array formation at all, if a martial artist could not withstand it, unless he retreated in time, no one could save him!

If Chu Fei was electrocuted inside, then it would be very dangerous!

"Elder Zhao, I only want to give it a try. Don't worry, the moment I feel that I can't hold on anymore, I will definitely withdraw."

"Sigh... "Fine!"

Looking at Chu Fei's firm expression, Elder Zhao seemed to have seen the Dongfang Yu of the past. These geniuses, they always liked to take risks, it was fine, but since he can't persuade him, he might as well let him try. With Chu Fei's alertness, once he finds out that he can't hold on any longer, it won't be a problem for him to withdraw.

Thinking up to here, the Elder Zhao could only open the lightning array's spell formation which was at the twelfth level of difficulty for Chu Fei.

RUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUU…!

Upon entering the twelfth level of difficulty, Chu Fei immediately felt pain in his ears from the sound of thunder. The twelfth level of difficulty was really not covered, it was completely different from the eleventh level of difficulty. Even the lightning and thunder were several times thicker than the eleventh level of difficulty.

No wonder even the practitioners of the Pulse Condensation Period could not hold on. Such a strong power of lightning, ordinary people simply could not withstand it.

"Let's give it a try!"

Although he was extremely terrified in his heart, and that was due to his reverence towards his natural instincts, Chu Fei did not have any thoughts of giving up. Since he had already entered, there was no reason for him to retreat! After taking a deep breath, he fully circulated the Burning Heaven Method and walked into the electric light.

Sou!

As the electrical light entered his body, the strong electrical current stimulated Chu Fei's body, causing him to jump suddenly, almost fainting on the spot. However, when the berserk electric current charged into his body, the spirit seed in his body actually reacted spontaneously, and was even throbbing faintly, as it let out excited whimpering sounds.

Then, Chu Fei was surprised to find that the terrifying electric currents had converged into a small stream that surged towards the spirit seed.

"What a strong power of thunder!"

If not for the spirit seed in his body, Chu Fei would not dare to challenge this level twelve lightning array, as the power of thunder and lightning was simply too terrifying, and he couldn't control it at all. However, with the spirit seed, this kind of crazy energy was compressed and sent into his divine seed.

"Chu Fei, are you alright?"

Just as Chu Fei was absorbing the lightning energy with all his might, the voice of the Elder Zhao rang out. He was still worried about Chu Fei's safety and could not help but ask.

"Elder Zhao, I'm fine!"

Chu Fei answered loudly. He knew that the Elder Zhao was worried about him and immediately responded to tell him that he was safe.

In the following time, Elder Zhao would ask once every five minutes, afraid that Chu Fei would have some sort of accident. Chu Fei also replied honestly, and just like that, two hours passed. When Chu Fei opened his eyes again, the thick thunderous energy had also become like an eleventh level of difficulty array scenario, with only a few pitiful tiny currents of electricity floating in the air. It did not have that shocking might of the lightning array at all.

The spirit seed in Chu Fei's body had already reached the size of a soybean, and an electric purple color appeared on its surface. It interweaved with the dark red power of fire, and the two types of lightning and fire interweaved, looking somewhat intelligent.

"Thunderheart!"

The red shadow sighed in amazement, "This power of thunder and lightning has actually formed a heart of thunder!"

Receiving the red shadow's reminder, Chu Fei focused on it, and it was true! With a Flame Essence, it was equal to having fire attribute energy. Now that he had a Thunder Heart, he could use lightning attribute energy, and there were extremely few martial artists with lightning attribute power, so although that Thunder Heart was small, once it grew, even his own ability would increase as well!

"This harvest... It's really big! "

Looking at the small spots of Thunderheart and Flame Essence, Chu Fei felt an unprecedented sense of accomplishment. This spirit seed was simply too mystical, it was just that he did not know how the spirit seed would change when the Thunderheart and Flame Essence grew together.

"Two... "Four hours..."

Elder Zhao, who had always been on tenterhooks outside, was really about to faint from fright this time. The stimulation Chu Fei gave him was getting stronger and stronger every time. Elder Zhao almost could not believe his eyes. No matter how heaven defying a human was, there must be a limit right? Chu Fei's level of cultivation, was simply too unbelievable!

"Chu Fei, are you alright?"

Elder Zhao could not hold it in and asked one more time, he did not know how many times he had asked that question, and every time he could hear Chu Fei's calm reply, and his voice was filled with energy, he did not seem to be injured at all.

But this time, Chu Fei did not reply, and was immediately shocked. He persisted for four hours, could it be that Chu Fei could not hold on any longer?

Just as Elder Zhao wanted to use his consciousness to enter the formation to take a look, he saw Chu Fei retreating out of the lightning array. The most important thing was that there were no wounds on his body at all, from top to bottom.

Right now, Chu Fei's mood was at an unprecedented level. This time, the fusion of the lightning energy was a success, and he had even nurtured a heart of lightning. How could he not be happy? Thus, when he saw the Elder Zhao, he immediately gave him a warm hug.

"Elder Zhao, thank you!"

"Thank me? "Why are you thanking me?"

Seeing Chu Fei's passionate look, Elder Zhao did not react in time. Chu Fei seemed to be fine, why did he become so enthusiastic all of a sudden? Could it be that his brain had been struck by lightning?

"Thank you for letting me enter the lightning array, thank you so much, hahaha …"

Chu Fei laughed in a good mood, he then waved his hand and said, "Elder Zhao, I won't be entering the array today, I'll go back first, see you next time!"

"Alright … "Next time, see you next time …"

The Elder Zhao replied in a daze. As he watched Chu Fei walk away with every three steps, he felt like his entire being was not right. Was Chu Fei really okay? Why does it feel so weird? To actually spend so much time in the lightning array of the twelfth level of difficulty, how did he do it?

No!

He had to go to the lightning array to take a look!

No matter how he thought about it, he just couldn't understand. In the end, the Elder Zhao had no choice but to enter the lightning array to investigate.
