It's been autumn for some time, and the trees in the valley are blowing under the cold wind, and the leaves fall to the ground one by one, and the golden yellow covers the ground.

In the valley, two shirtless teenagers stood in a clearing, and although it was cold, their bodies were constantly steaming.

Silver lightning came one after another, and the two of them were pressed for time to breathe, and after defending one, the next one came to their eyes.

"It's still too slow, Xiao Yu, you just need to defend with all your strength, feel the feeling of the power of thunder hitting your body, and strengthen the meridians in your body!" Jing Yu stood there like a green pine, and with the wave of his arm, the silver power of thunder would draw an astonishing arc.

Although Hei Yu was reluctant to accept this thunder refining body at the beginning, Jing Chen, the ninth-order Qi Yuan Realm, could insist, and he also taught Jing Chen.

"Chen'er, restrain your Fire Yuan Qi, don't try to use the Fire Yuan Qi defense in your body, your Fire Yuan Qi will conflict with the power of thunder, and the defense will be dangerous!" Jing Yu said.

The fiery red Yuan Qi covered by Jingchen's body slowly converged towards the dantian, and after a while, there was no defense.

But the movements of Jing Yu's hands were not merciless, the power of thunder hit Jing Chen, without Yuan Qi's protection, a light white mark remained in his chest, Jing Chen gritted his teeth in pain, and forcibly did not call out.

This thunder power hit his body with a little paralyzing effect in addition to pain, and the number of times was very frequent, almost after Jing Chen adjusted it slightly, the second thunder power hit his body again.

This kind of cultivation has a great drain on both physical strength and Yuan Qi. However, Jingchen's Yuan Qi consumption is okay, his main purpose is to feel the power of thunder, if he can incorporate a trace of thunder power into his body, then his task will be completed.

At the end of the first day, Jing Chen insisted on a total of twenty-five thunder powers, while Hei Yu persevered forty times.

Jingchen did not incorporate the power of thunder into his body, and the defense on the first day seemed a little difficult, if he wanted to completely resist the power of thunder, and then incorporate it into his body, Jingchen already felt some difficulties in this process.

Jing Yu looked at the tired and paralyzed appearance of the two brothers, and nodded with satisfaction, this is the effect he wants.

Hei Feng quietly appeared beside Jing Yu, looked at the two children, and said, "Big brother, you are still amazing, that stinky boy complains about the hard work of cultivation all day long, and he doesn't even dare to fart when he comes to you!"

Jing Yu smiled and did not speak. Although the cultivation was very hard, fortunately, they ate well, and the fatigue of the two of them for a day disappeared in an instant under the temptation of food.

When Jingchen got up the next day, he found that the meridians in his body were much tougher than the day before, and this was the only improvement after the Kunlun Divine Scroll cultivation was completed. Thinking back to the thunder power he endured during his cultivation yesterday, all this hardship was very worth it.

Hei Yu also felt the changes in his body, and shouted excitedly, as a strange beast, it was very difficult for him to improve the toughness of his meridians, but he didn't expect to see results in just one day with Jingyu's method.

After Jingchen came to this world, he had been cultivating almost all the time except for the first half of the year, and in less than two years, he had stabilized at the ninth-order Qi Yuan realm, although it was a little worse than a truly talented person, it was not bad.

Since tasting the sweetness, the cultivation of the two has become more attentive, Jingyu only needs to constantly whip the two with the power of thunder every day, and now the two little guys will not say anything to complain.

The two seem to be more energetic, as long as one person doesn't shout to stop, the other person will never take the initiative to speak, even if he can't support it, he never says.

In the early days, because Jingchen couldn't use Yuan Qi, he would faint before Hei Yu almost every day.

When Ye Ling came over with food every day, Jingchen was almost lying in a huge wooden basin, which contained Jingyu's medicinal liquid, which could dissolve the blood congestion in his body, and even then made Ye Ling feel distressed.

However, after soaking in the wooden basin for a while, Jingchen will wake up, although this liquid is not a elixir, but it is very effective in healing, as long as you soak here for a while, sleep well at night, and the next day you will be refreshed and in a better state.

After a month, Jingchen also slowly explored the characteristics of this thunder power, although it was very violent, but it was only the moment it hit the body and felt pain.

After persisting for so long, Jingchen's body also has a certain resistance to the power of thunder, and after being baptized by the power of thunder every day, he can feel the changes in his body. Subtly, there was a little bit of thunder attribute in Jingchen's Huo Yuan Qi, although it was very weak, but Jingchen finally saw a little hope.

At this time, Hei Yu had already advanced to the sixth-order Yuan Force Realm, but the Yuan Force Seed in Jing Chen's body showed no signs of condensing.

It stands to reason that there is no big problem with the current Jingchen Condensation Yuan Force Seed, but after a few attempts, it always ends in failure.

Jingyu also warned Jingchen not to worry, although it can't be condensed now, it will also be of great benefit to the future, which is the so-called accumulation.

After his father's enlightenment, Jingchen was not in a hurry, and in addition to cultivation, he could only learn from Hei Yu every day. Although he would be beaten by Black Feather every time, and then shake his head and admit defeat amid that baboon-like laughter. However, Jingchen was not discouraged, but became more and more courageous.

The pressure brought to him by Black Feather was much stronger than that of Na Chu Nature, and he could feel the gap between himself and Black Feather, and only in this way could he motivate himself to keep improving.

After enduring the baptism of thunder power for a month and a half, the Yuan Qi in Jingchen Dantian finally had a trace of thunder attribute!

After perceiving the Thunder Attribute Yuan Qi, Jing Chen was excited for a whole day, although this did not increase much in the battle, but in the future, Yu Yu once said that he would teach Jing Chen a body technique Yuan Technique.

Presumably, that body magic technique has a close relationship with this thunder attribute, and this also provides a certain guarantee for absorbing the space spirit gold and thunder speed pill in the future!

The current Jingchen, after a month and a half of cultivation, has become more condensed, although it is slightly thin compared to Black Feather, but it contains full explosive power. His half-long hair, which had fallen over his shoulders, also hung down, and he didn't look like a twelve-year-old at all.

"Chen'er, don't be in a hurry to be happy, this is just the beginning, now the thunder attribute in your body is too weak, you have to temper it more!" Jingyu looked unfazed, but he was very happy in his heart, Jingchen was able to improve to this level in such a short period of time, it was already very good.

Jingchen nodded, suppressed the excitement in his heart, and grimaced at Hei Yu, now his hard life can be regarded as over.

"Chen'er, come here, since you have absorbed the power of thunder, now is the time to teach you that Fa Yuan Technique!" Jing Yu looked at Jing Chen's smiling face and said solemnly.

Jingchen nodded, and said secretly. What Jingyu does has always been in line with the rules and regulations, and she will never do useless work. What Jingchen didn't expect was that his hard life was only half over!

"Today I will pass on to you a body technique called - Thunder Wanjun!" Jing Yu said, his palm was raised, and a terrifying momentum emanated, Jing Chen couldn't help but take a step back, although he had seen Jing Yu's strength, but he had not felt it so closely.

Jingchen only felt that his body was suppressed and couldn't move. The moment the momentum exploded, some of the strange beasts living not far from the valley let out a wail, obviously frightened by Jing Yu's sudden momentum.

Hei Yu on the side hurriedly hid in the distance, although he had already seen Hei Feng's strength when he was cultivating, but it was the first time he had seen Jing Yu shoot, and it was even stronger than Hei Feng.

"Heaven and earth are infinite, Qiankun borrows the law!" Jing Yu recited a spell in his mouth, and with the seal in his hand, a wisp of gold condensed between his index and middle fingers, and slowly moved towards his head in Jingchen's dilated pupils.

A huge amount of information surged in Jingchen's mind, in the eyes of the outside world, Jingchen seemed to be scared stupid, there was no look in his eyes, and his facial muscles were a little stiff, with Jingchen's current state, I am afraid that any ordinary person can kill him!

"Thunder Wanjun, Thunder Attribute Body Law Yuan Technique, Spirit Rank Low!
