Shen Feng was also relieved after hearing this, but after thinking about it, it was normal for a black light to appear from the thunder dragon, after all, he existed in the eyes of the sky, which was different from the products of ordinary heaven and earth.

Shen Feng asked

"What's the next level?"

The lightning dragon said slowly

"The next level of assessment is to defeat me."

Shen Feng's eyes were also wide at this time, after all, the thunder and lightning dragon in front of him was a hundred zhang high, and his own thunder dragon could reach a height of 10 zhang at most.

The Thunderbolt Dragon also saw Shen Feng's concern, so he spoke again

"Height doesn't determine everything, and don't underestimate the potential of our ThunderClan Dragon, they all say that Thunder and Lightning is the most powerful in the world, and the reason why they say this is because he has infinite possibilities."

Shen Feng nodded, then glanced at the Thunder Dragon, and the other party also nodded at Shen Feng, signaling that he could accept this challenge, so Shen Feng did not intend to delay, and immediately commanded the Thunder Dragon to rush towards the Thunder Dragon.

In an instant, the two of them were at war together, and it was obvious that the Thunder Dragon had an absolute advantage, and the Thunder Dragon was beaten without the power to parry.

A wail came from the thunder dragon's mouth, even so, he had no intention of giving up, Shen Feng and his heart were heart-to-heart, he could feel the thunder dragon's heart wanting to become stronger.

Under the attack again and again, each time he was thrown out only the moment he touched the thunder dragon, and he could clearly hear the sound of him falling to the ground and his bones crackling.

Even though he was covered in bruises and the corners of his mouth had begun to bleed profusely, he had no intention of giving up, and Shen Feng couldn't stand it anymore.

If it was him who fell now, then he didn't have any intention of feeling distressed, but this time it was his partner who shared his weal and woe, Thunder Dragon, and his heart was aching.

However, Shen Feng also knew the measure, he knew that the thunder dragon had paid such a heavy price, just to become stronger, and to help Shen Feng reach the perfect knot realm.

After three hours passed, when the thunder dragon was struck by the lightning dragon, he fell to the ground, completely motionless.

Shen Feng was in a hurry, he hurriedly came to Lei Long's side, shook his body and asked

"Brontosaurus, how are you, wake up."

At this time, the thunder dragon did not move at all, and at this time, the thunder dragon made a sound

"Don't worry, he can't die, he's the most potential dragon in our ThunderClan."

With Shen Feng's understanding of Lei Long, he knew that the other party would definitely not die like this, but he was also very uncomfortable when he saw that the other party looked dying.

Finally, after an hour had passed, the thunder dragon slowly opened his eyes, and he nodded his head at Shen Feng, signaling Shen Feng not to worry, he was fine.

Shen Feng saw that he woke up, and he was relieved.

After a short period of repair, the thunder dragon was immediately entangled with the thunder dragon again, and it was obvious that this time the thunder dragon's strength was much greater.

After a short confrontation, the thunder dragon did not fall behind, and this scene also made Shen Feng's eyes wide.

After they fought for three hours, the Thunder Dragon quickly adapted to the rhythm of the Thunderbolt Dragon, and even fought to a draw.

In fact, this sudden change of the thunder dragon also surprised the thunder dragon, he knew that the thunder dragon in front of him had unlimited potential, but he didn't know that in such a short time, he could stimulate such a great potential.

Maybe the thunder dragon himself didn't feel the change he was in, he was just fighting the thunder dragon in one go, and his strength was growing at a speed that was visible to the naked eye.

In this way, they fought for another 7 days and 7 nights, and the Thunder Dragon finally defeated the Thunderbolt Dragon.

The lightning dragon said with a sigh

"I didn't expect your strength to grow so fast, and you can defeat me in just this time, since this is the case, I will give you a creation."

After finishing speaking, he took out something similar to an elixir from his hand, his surface flashed with golden light, Shen Feng didn't know what was in front of him, but Lei Long could, he opened his eyes wide and howled towards the sky.

Shen Feng heard what he was about to say, so he turned his head and said

"You're saying this is the Dragon Pill, the legendary Dragon Pill that can make all dragon creatures increase their strength?"

The brontosaurus nodded at him.

Shen Feng looked at all this incredulously, after all, having Long Dan was like having an imperial throne in the mortal world.

The Thunderbolt Dragon threw the Dragon Pill in front of the Thunder Dragon and said

"This is what I mean by creation, you can swallow this dragon pill, I think your strength will change by leaps and bounds."

The thunder dragon swallowed it into his mouth after taking the dragon pill, and then a golden light shot out from his body, and after he screamed, he began to hover in mid-air.

After seeing this scene, the thunder and lightning dragon nodded with satisfaction and said to Shen Feng

"He's already digesting that dragon pill, and when it's finished, you can get out of here, but the digestion time is long and short, so please be patient."

With that, he disappeared in place.

Shen Feng didn't rush after hearing this, but meditated cross-legged on the spot and waited.

A month before the end of Shen Feng's one-year lifespan, the thunder dragon had not yet woken up, Shen Feng opened his eyes at this time, Shen Feng was a little anxious at this time, after all, his life was running out.

He could clearly feel that his body was aging rapidly day by day, and it was more intense during this time.

But he also knew that this matter was not in a hurry, so he decided to wait a little longer, if the thunder dragon had not woken up, then he had to think of other ways to make himself reach the level of ten percent of the knot.

In this way, he waited quietly for half a month, and at this time, the thunder dragon finally reacted, and his body began to move slowly.

After Shen Feng waited for another 10 days, the thunder dragon finally raised his head to the sky and let out a roar, waking up from the state of digesting the dragon pill.

At this time, his strength has changed by leaps and bounds, and at this time, a layer of golden light emanates from his body, and his aura gives people the feeling that it is deterrent.

Especially his eyes, which made people look cold, Shen Feng hurriedly ran up, touched his huge dragon head and said

"Thunder Dragon, your strength has increased a lot, you have suffered during this time, and when I also complete the process of knotting Dan, I will definitely let you have a good rest."

"So in the next few days, you will accompany me through the process of knotting."

After hearing this, Lei Long nodded directly, and then he plunged into Shen Feng's heavenly eyes, and Shen Feng immediately left the thunder and lightning area.

As soon as he came out, he saw that Elder Chiyang was already waiting outside, and asked anxiously

"Why did you use it for so long, don't you know that you only have a year, let's go, let's go back quickly, don't miss a big thing."

Shen Feng waved his hand and refused

"Elder, no need, the time given to me is running out, can you please find an area nearby for me to start the knot."

Elder Chiyang said after thinking about it

"Okay, just do as you say, after all, time is running out, let's go, I'll take you to a place."

Then he left with Shen Feng from here, and it only took them a day to come to a mountain peak.

Elder Chiyang said

"This is where I often come to, you can go here to break through the Jiedan Realm with peace of mind, I will give you Dharma protection here, and no one will come here to disturb you."

Shen Feng nodded, then found a cave and walked in, with a Divine Transformation Stage cultivator like Elder Chiyang protecting his Dharma, then he didn't need to worry at all.

If there were enemies that Elder Chiyang couldn't deal with, then he was even more powerless.

Shen Feng meditated cross-legged in place, and it took him a day to restore his cultivation to its peak state.

Then he took the token given to him by the Forbidden Sect Master in his hand, so that he could save some effort, and he could reach the level of ninety out of nine.

But Shen Feng also knew that assistance was assistance after all, and if he wanted to make his cultivation more stable, then he still needed to rely on his own strength to achieve it.

After doing this, he began the knotting process.

Shen Feng condensed all the spiritual energy into the dantian, and then began the process of building the inner dan.

With Shen Feng's prerequisites, he quickly completed one percent, then two percent, three percent, and it wasn't until the fifth percent that his speed of condensing Neidan slowed down.

Although the speed is slow, it is still moving towards the level of 60%.

In the past two hours, he has completed the process of shaping fifty percent of the inner dan.

However, in the process of shaping Liucheng Neidan, he encountered huge resistance, as if a pair of invisible hands were blocking him.

Shen Feng didn't choose to use time to dilute this process, but directly punched the aura into the token in his hand, and soon his body was surrounded by a soft force.

In one fell swoop, he broke through the resistance to shaping Sixty Percent Neidan, and his speed began to get faster, so this time it took him a short time to reach the level of seventy percent.

At this time, a large amount of aura is needed to assist, and Shen Feng has a golden sand pill in his body, so it can provide Shen Feng with a large amount of aura.

With the assistance of these aura, Shen Feng began his process of shaping the 7 Cheng Yu Dan.

The whole process was relatively slow, but Shen Feng was not in a hurry, because he knew that he had to take every step steadily in order to achieve the result he wanted in the end.

In this way, under his slow ascension, he soon broke through seventy percent and reached the level of eighty percent, and this time the required aura increased exponentially.

At this time, his golden sand pill shrank at a speed visible to the naked eye, and when it was about to reach the level of ninety percent, the golden sand dan was completely exhausted.

Shen Feng was also quick enough to react quickly, and directly injected the aura into the token in his hand, and immediately he was replenished by the aura, and these auras also supported him to the level of ninety out of nine.

The last zero point one needs to be completed by himself, and the only thing that the token can provide him with is the support of the aura.

Without the slightest hesitation, Shen Feng immediately summoned the Fire Phoenix and the Thunder Dragon, and under Shen Feng's order, the Fire Phoenix and the Thunder Dragon spat out the fire and thunder respectively.

The location they arrived at was the Dantian, the Inner Dan shaped by Shen Feng, and under the wrapping of fire and thunder, he began to try to attack the Ten Percent Yudan.

The process seemed very slow, as if time had stood still, because Nedan had not changed in any way, as if he had reached his limit and there was no possibility of breaking through.

But Shen Feng is not an ordinary person, his purpose this time is to reach the level of Ten Percent.

Under the action of fire and thunder, it was not only Neidan who was impacted, but also Shen Feng's body, and his body was suffering greatly at this time.

Because fire and thunder cannot be absorbed by Neidan, the excess power needs to run inside the body.
