Xu Dong injected divine thoughts into the light green jade ring on the ring finger of his left hand, and the second volume of Yin and Yang Fire slowly opened, turning to the tenth page at the end.

He activated the "Heavenly Eye" of the Purple Mansion, carefully interpreted the content on the page, and began to practice the tenth paragraph of Yin and Yang Fire.

The tenth stage of practicing Yin and Yang Fire, like the previous stages, is divided into five stages: cultivation, trial, fire resistance, metallurgy, and synthesis, but the specific methods are much more complex and refined than before.

As the temperature of the furnace increased, the Condensing Fire Pill and the Zhuji Pill were refined in the body, and the mixed medicinal properties enhanced the medicinal power, and the thick fire attribute spirit element in the Ding Furnace was devoured, and then condensed into essence seeds in the body.

After the essence seed is conceived, it continuously produces fire attribute spirit elements, and after the spirit yuan is full, it is swallowed by the large and small blood vessels around Xu Dong's body, and then it is full and devoured again......

The temperature in the furnace continues to rise, the fire power is increasing section by section, and the color of the flame will be red, green, and white and yellow.

"Resist the fire!"

Xu Dong tried his best to control the fire in his body, kneading the fire into different geometric shapes, sometimes round, sometimes square, sometimes like a lion's head, sometimes like a spirit snake.

After being able to control this fire at will, he tried to extract the yin fire in Yaqian's body, and transformed it from a single yang fire to a compound fire of yin and yang, and this step was "smelting".

At this time, Yaqian has recovered, and the indicators of her body have returned to normal values, but her consciousness is not clear enough, and her throat is still unable to swallow and suck involuntarily.

Xu Dong put the Condensing Fire Pill into his mouth first, and then kissed Yaqian for a long time, as the Condensing Fire Pill was slowly contained, he continuously instilled the medicinal power of the Condensing Fire Pill into Yaqian's body.

Yaqian's breath changed from thin to thick, constantly devouring the fire attribute spirit element in the Ding Furnace......

Xu Dong was also too tired, and with the warming effect in the Ding furnace, he actually hugged Yaqian tightly and fell asleep.

"Xianggong, save me!

He heard Yaqian's call in his dream, and when he went back to the moment when Yaqian was kidnapped in Xianju two years ago, he jumped up and grabbed his sword to fight that man......

"Xianggong, hold me tight!"

"Hold me tight, I'm cold, I'm cold...... I'm so cold!"

Xu Dong was startled, he woke up from his dream and found that Yaqian was completely awake, she trembled involuntarily, and the two rows of snow-white teeth were also fighting.

He knew that Yaqian had been frozen by the Arctic ice for two years, and a huge amount of cold had accumulated in her body, and at this moment, this cold was driven out by the high temperature in the Ding furnace.

"Yaqian, you have suffered for me! I am sorry for you! I am sorry for you!"

Xu Dong thought that if Yaqian hadn't taken loyalty so seriously, and agreed to follow Lin Dan at the beginning, she would never have suffered from more than two years of sealing......

Thinking like this, he was even more grateful to Yaqian in his heart, and swore that he would be good to Yaqian in the future.

"Xianggong, I'm cold, cold, so cold!"

Xu Dong was so distressed that he clung to Yaqian tightly, hating that he couldn't exchange his hot heart for Yaqian's cold heart, so as to alleviate Yaqian's pain.

"Xianggong, is that you? really you?"

Yaqian looked at Xu Dong with wide eyes, as if she had just woken up from a dream, her eyes were a little confused, and she struggled to stand up.

Xu Dong held her down, "Yaqian, it's me, it's really me, I'm Xu Dong, don't move, it's okay for a while!"

"Xianggong, where is this? It doesn't seem to be Tongtianguan here, did you rescue me?"

"I rescued you, Yaqian, this is in the Lotus Cave of Bigu, put you in the Danding to bake, mainly to force the cold in your body out, don't move, it'll be fine for a while!"

He sighed in his heart, how stupid this woman is! If he Xu Dong didn't become strong and didn't practice the sixth stage of yin and yang fire, Lin Dan wouldn't have asked for him, and he would have sealed Yaqian forever.

Obviously, when Yaqian made her choice, she was determined to die, and she would rather die herself than keep her chastity.

Xu Dong was moved wave after wave in his heart, he was so moved that he kept kissing Yaqian, kissing almost every inch of her skin......

I don't know how long it took, the flame in the Ding furnace gradually went out, and Xu Dong and Yaqian were slowly raised and soaked in the warm pool.

Yaqian suddenly returned to reality from the unreal, seeing that she was naked and being held by Xu Dong, who was also naked, she was so scared that she didn't know what to do, and subconsciously pushed Xu Dong away.

Xu Dong's strength recovered, and the bottom was already erect, but he didn't dare to contaminate Yaqian's body, for fear of destroying this rare holiness, he regarded Yaqian as a holy goddess.

............

Because two elixirs were used at the same time in Taishi Ding, Xu Dong wanted to test whether it had an effect, so he recited the spiritual formula, and the faint blue light on the stone curtain slowly appeared.

He breathed in on the open stone curtain, and after intercepting his sucking, a beating band of light appeared on the stone curtain, and then the band of light gradually stabilized.

"Foundation Realm, Fourth!"

Seeing these words on the stone curtain, Xu Dong was overjoyed, which marked that he had entered the middle stage of the foundation building realm.

It took him more than two years to start from scratch and shape himself into a strong man, and he knew that it would take at least ten or even decades for ordinary people to complete this step.

He also checked the rank of the Yin and Yang Fire, analyzed it from various indices, and finally combined all the data to indicate that his Yin and Yang Fire had reached the tenth stage to the letter.

"Oh yes!"

He knew that the reason why he was able to win these two indicators in one fell swoop and reach two peaks at the same time was mainly due to the help given to him by Yaqian's pure yin body.

As soon as Xu Dong was excited, he wanted to kiss Yaqian, at this time Yaqian was already dressed, and her solemn expression could not hide her beauty, and that rare gentle temperament, in this aura cave, Yaqian was also sublimated.

He couldn't help but be impulsive, hugged Yaqian, made three turns in the front, and turned three times in reverse.

Yaqian was dizzy, grabbed Xu Dong's arms with both hands, and stepped her face into his arms, so as not to fall all of a sudden.

She smashed Xu Dong's sturdy shoulder with her small fist, "You are bad! You are bad! Deliberately dizzy me in an attempt to take advantage of me!"

Xu Dong said, "Fei Ye, Fei Ye, you are my wife, what is the advantage to take advantage of?"

"Then what do you mean by turning me left three times and right three times?"

"You don't understand this, isn't there such a folk saying? If a mortal raises a cat or a dog, as long as he holds it three times and feeds it, he can't run anymore!"

Yaqian smiled beautifully, "Is that so? Or are you bad! Or are you bad! Are people that kind of wild woman?"

Xu ** suddenly made a decision not to return the godhead on Yaqian's body to Chaochao, he waited for the opportunity to find the godhead to return it to Chaochao.
