The gold box is as big as a tea cup, with nine carved gold flowers, it is undoubtedly a royal thing, the gold box starts, Zuo Dengfeng immediately feels like a deer, gold can not block the aura, he feels the faint mixed element aura emitted from the inside of the gold box.

Although the gold box has been placed for a long time, but the golden yellow and bright is not covered with dust, Zuo Dengfeng opened the lid with trembling hands, and found that the gold box was padded with soft brocade yarn, after three thousand years, the brocade yarn did not fade at all, and there was a very small inner dan in the middle of the brocade yarn, with colorful streamers, and both five elements, which was the inner dan that had been lost for many years by the thirteen.

The inner dan of the ordinary earth branch has the size of a little finger and a belly, shaped like a bean grain, but the inner dan in the box is as small as a grain of wheat, according to the brocade yarn depression traces of the cushion gold box, the thirteen of this inner dan should be slightly larger than the inner dan of the earth branch, and the reason why it is so small now is because the gold box can not isolate the divergence of aura, and the aura contained in this inner dan has slowly volatilized out after three thousand years.

When Zuo Dengfeng was stunned with the gold box in his hand, a fresh breath came from his side, Zuo Dengfeng turned his head to look, and found that it was Yufu who leaned over and looked down at the inner dan in the gold box.

After a while, the two of them retracted their gaze and glanced at each other, both of them shook their heads with a wry smile, the thirteenth Inner Dan diverged too seriously, but this can't be blamed for the improper disposal of the old way, the iron tool can block the aura, but the iron tool of three thousand years will definitely not be able to be preserved to this day.

Although this inner pill is less than one-tenth of the previous one, it is extremely mellow, and it contains the five elements of each qi, which is noble and golden, tenacious and elegant wood, clear and clear of water, tyrannical and domineering, and earthy and heavier than Sumeru.

Zuo Dengfeng held the gold box thoughtfully, and after a while, he resolutely squatted down and handed the gold box to the thirteen, everyone has selfish intentions, Zuo Dengfeng saw this Neidan and gave birth to the idea of saving Wu Xinyu with it, but this dark idea was denied by it in an instant, this is a thirteen thing, must be given to thirteen.

His decision was very resolute, the reason for the decision was not because of the unknown number of Wu Xinyu who used this Neidan to save Wu's heart, but because he couldn't see profit and forget righteousness, and he would take revenge, although dark thoughts appeared in his mind, Zuo Dengfeng did not feel guilty about it, because everyone has dark thoughts, and being able to suppress this dark idea in an instant is already beyond the surname.

Thirteen was very unfamiliar with the golden box, but it was not unfamiliar with the contents of the golden box, but at this moment its expression was puzzled, and after taking a look at the golden box, it looked up at Zuo Dengfeng, and the meaning expressed in its expression was very obvious, "Why is my Neidan so small." ”

"That's all there is to it." Zuo Dengfeng couldn't cry or laugh when he saw this, and the jade whisk next to him also looked helpless.

Thirteen didn't get an answer from Zuo Dengfeng, so he lowered his head and sniffed the Nedan in the golden box, it wasn't that it couldn't feel that this Nedan belonged to itself, it just wondered how the Nedan that was originally as big as a pigeon's egg became like this.

After a moment of sniffing, the thirteen mouths swallowed the Nedan.

Neidan entered the body, and the gray hair around the thirteen bodies suddenly turned golden in an instant, which is a thick and domineering noble yellow, far from being comparable to the dazzling and cheesy vulgar yellow, and the gray hair changed color and grew a few inches at the same time, just like a general hanging his shirt, the son of heaven was wearing a robe, and he suddenly showed honor and domineering, and his grace was extraordinary.

Thirteen's facial features also have subtle changes, and in an instant, three inches long and short upward punch hairs are born in both ears, which are different from the black hairs of the lynx, and the hairs born by Thirteen are dark red in cinnabar, corresponding to the color of the claws.

Although there is no obvious change in the eyes, the curtains are slightly drooping, and there is a calm spirit inside.

The nose wing is still black, but this black is not the other black, the previous black is the black of ink, and the black at this time is the black of ink jade, although it is also black, the gods are very different.

The mouth has not changed, but the canine teeth on both sides of the palate have become longer, slightly exposed, and slightly aggressive.

The change of thirteen was completed in an instant, and after a short moment, Zuo Dengfeng knew that he was about to lose thirteen, at this time the thirteen expressions were extremely majestic, without the previous surname, as if the Son of Heaven returned to the throne, the two could be close friends before the yellow robe was added, but the two could not be friends after facing the south and the north.

"Thirteen is really mighty." Seeing this, Yufu felt that she had not been with Thirteen for a long time, and she could not see the subtle changes in Thirteen's expression.

Thirteen Wenyan looked up at the jade whisk, and then looked at Zuo Dengfeng, its eyes at the moment were like an old man who had been in the world for a long time, and it was no longer stubborn and stupid, which showed that swallowing the inner pill brought it not only an increase in strength and a change in appearance, but also had a great impact on its heart and intelligence.

After looking at the two of them, Thirteen turned around and walked towards the Five Elements Spirit Land on the west side, at this time its tail was no longer upturned, but mopping the ground straight, the tip of the tail was slightly flicked, the pace was very slow, and it slowly crossed the five circles into the yellow mud pit in the middle and lay down.

Thirteen usually likes to lie on his stomach, but this time it is reclined.

Seeing this, Yufu turned her head to look at Zuo Dengfeng, with an inquiring expression, and it was obvious that she had also found that Thirteen had separated from Zuo Dengfeng.

"It's homeless, and I'm relieved." Zuo Dengfeng said calmly, at this moment he understood that there was no feast in the world, he was very depressed and lonely, whether it was a jade whisk or an iron shoe, it was just his temporary partner, only Thirteen had been following him, once Thirteen left, he became a real loner, and he didn't even have an audience to talk to.

Yufu shook her head and sighed lightly when she heard this, Thirteen's attitude made her feel the danger, this danger was not about Thirteen, before this she had always regarded Thirteen as a comrade-in-arms, and the two worked together to pull Zuo Dengfeng, who was all the way to the underworld, to the yang world, and now Thirteen has returned to his homeland, Zuo Dengfeng has one less attachment to the world, and it is difficult for Zuo Dengfeng to turn back by her alone.

"Let's go." Zuo Dengfeng glanced at Thirteen and turned around and walked away, the reason why he came here was only for Thirteen, and the others were indirectly caused by Thirteen, and now Thirteen's attitude made him very disappointed, but he didn't blame Thirteen, because before he found Nedan, Thirteen was like a fool, and his relationship with Thirteen was based on its mental chaos, and now it has woken up.

"After reading these two stone slabs, let's go, at least know the identity of the original owner of the thirteen." The jade whisk probe grabbed the left peak, the grotto is divided into three layers, and the upper and lower two layers each put a stone slab.

"What does it have to do with me." Zuo Ascending did not stop.

"The second stone tablet is carved as if it were a method of attracting dragon souls." Jade Whisk tried to make Zuo Dengfeng stay here longer, waiting for the thirteenth time to change his mind.

"I already have the yin and yang life and death formula." Zuo Dengfeng still hasn't looked back.

Hearing this, Jade Fu could only pick up the two stone slabs and walked out of the cave.

"Put it back, the lama didn't take anything, and you don't want to take it either." Zuo Dengfeng shook his head and said.

Yufu didn't listen to Zuo Dengfeng's words, sighed and walked side by side with Zuo Dengfeng to the entrance of the cave, Zuo Dengfeng's face was gloomy and scary, she didn't know how to be relieved.

While walking, Zuo Dengfeng was thinking about whether Thirteen would encounter survival difficulties here, after all, there was not much left of its Inner Dan, and he didn't blame Thirteen for staying in his homeland, he just felt cold all around.

Just as Zuo Dengfeng approached the entrance of the cave, Jade Whisk grabbed him.

Zuo Dengfeng turned to look back and found Thirteen standing at the entrance of the cave looking at him.

"Go back, I'll see you if I have time." Zuo Dengfeng smiled and waved his hand at Thirteen, after the life and death parting with Wu Xinyu, he already understood that men should restrain their feelings, hide them in their hearts, engrave them in their bones, but they can't be shown to the outside, but these are just his rational thoughts, and he can't do it in his heart, his eyes are already red when he speaks, and he knows very well that he will not come back.

Thirteen didn't react when he heard this, just stared straight at Zuo Dengfeng, his eyes showed a solemn and embarrassed look, Zuo Dengfeng was relieved when he saw it, he didn't want anything else, as long as Thirteen showed a trace of nostalgia for him.

Zuo Dengfeng didn't make Thirteen embarrassed, Thirteen stayed here is the best choice, sooner or later one day it can rely on the spirit to recondense the Inner Dan, and then control the Heavenly Dragon, after a while, Zuo Dengfeng retracted his gaze and walked towards the entrance of the cave and bent down.

At this moment, Thirteen screamed and pounced on the two of them, leaping ten zhang away, several times the previous jump distance, and the entry of Neidan into the body had a great impact on it.

Thirteen came to Zuo Dengfeng to look up, his face was reluctant, Zuo Dengfeng responded with a smile, raised his hand and pointed to the cave, signaling it to go back, he didn't dare to speak, because Yufu was near, he didn't want Yufu to see his weak side.

Thirteen kept staring at Zuo Dengfeng, and after a long time, the hesitation in his eyes gradually disappeared, replaced by incomparable perseverance, if this expression appeared on the face of a human being, it meant that this person had made a major choice.

After a while, Thirteen's eyes turned confused, as if a human being was stunned, Zuo Dengfeng was puzzled when he saw this, and called out twice, but Thirteen didn't respond.

"What's wrong with Thirteen?" Seeing this, Yufu was puzzled.

"I don't know, it's never been like this before." Zuo Dengfeng shook his head and said.

As soon as the two of them had spoken a few words, they heard a loud rumbling sound coming from under the cliff on the east side, which indicated that there had been a great change under the mountain.

When the two of them heard the sound, they immediately walked to the edge of the cliff and looked down, and were suddenly shocked at a glance, the area on the east side of the mountain was originally a frozen deep lake, and at this moment the ice surface of the ice lake had been broken, and a giant dragon was spinning up from the water in the ice lake, and it was in front of him after a while.

This is a real dragon, with a body length of 100 zhang, golden scales all around, a six-foot dragon horn on the head, a nose that is too wide to a foot, a wide mouth, red dragon eyes, several times the bull's eye, the scales are thick, golden and flawless, the dragon's whiskers are raised, dancing and powerful, the abdomen is full of five claws, vigorous and sharp.

The five-clawed dragon and even the genus of the golden dragon, the golden dragon was born, the auspicious clouds surrounded the body, the wind and clouds changed color, and the moon was lightless.

The sudden appearance of the golden dragon stunned Zuo Dengfeng and Yufu, although they had guessed that Thirteen had the ability to control the dragon before, but they never thought that the dragon derived from it turned out to be the Supreme Golden Dragon, Zuo Dengfeng did not expect that the Thirteen would summon the golden dragon at this time, there was very little left of its inner Dan, and summoning the golden dragon at this time would inevitably lead to the exhaustion of its inner Dan and could not be recovered.

Thinking of this, Zuo Dengfeng immediately turned his head to look back, and found that Thirteen was running towards here, the previous golden retriever was already extremely dim at this time, the gold was almost gone, the upper jaw canine teeth and the binaural brush hair had been retracted, and the appearance was extremely sluggish, but his expression was extremely excited, and he quickly ran to the edge of the cliff to look at the five-clawed golden dragon.

"Why did Thirteen summon the Golden Dragon at this time." Jade Fu looked back in amazement, Thirteen was obviously out of place to summon the Heavenly Dragon at this moment, and it would exhaust the only remaining Inner Dan.

"It wants us to see what it's really capable of." Zuo Dengfeng pulled the jade whisk back, the golden dragon was already swinging its tail at this moment, there was no doubt that it was going to smash this aura barrier and meet the thirteen.

"Why would Thirteen do this?" Jade Whisk asked again.

"Because it has already made its choice, this is the last time it will ride the golden dragon......"
