Lu Feng's teeth were chattering up and down, and Xu Man was the same, his whole body was trembling, and beside the two of them, the fire spirit stone exuded a scorching aura, which could offset some of the cold.

"What a domineering medicinal property!" Lu Fengdao, he remembered Luo Yi's previous advice.

The Heavenly Snake Cold Pill is a powerhouse like Luo Yi who has achieved great success in the True Qi Realm, and the medicinal properties of the elixir used in cultivation are naturally extraordinary, and it is not comparable to the ordinary Nine Rank Spirit Pill.

Before leaving, Luo Yi specially told Lu Feng to be cautious about using the Heavenly Snake Cold Pill, the fierce medicinal properties of the Heavenly Snake Cold Pill were beyond Lu Feng's expectations.

If it is replaced by other martial artists who have just begun to quench their bones in the fifth level of the foundation building period, they will not be able to swallow the Heavenly Snake Cold Pill at all, otherwise they will be in danger of freezing to death.

The blood stains all over Lu Feng's body were about to freeze, and he breathed and absorbed, absorbing the scorching breath emanating from the Fire Spirit Stone to offset the cold of his body as much as possible.

It's just that the scorching aura emitted by the Fire Spirit Stone is a relatively slow process, and the medicinal properties of the Heavenly Snake Cold Pill are suddenly exploding, although they come and go quickly, but in the time of the outbreak of the medicinal properties, the two are not enough to counteract.

"Careless!"

Lu Feng secretly said in his heart, with such a fierce medicinal power, Lu Feng was a little unable to resist, and he didn't expect that the medicinal properties of the Heavenly Snake Cold Pill would be so domineering.

Luo Yi's advice is right, even if Lu Feng's physique is stronger than other five-fold powerhouses in the foundation building period, the method of breathing and exhaling is extraordinary, and with the fire spirit stone by his side, he will not be frozen to death, but if he continues like this, his body will be frostbitten, and after the physical injury, even if he is not disabled, he will have to go through a long period of cultivation, and then the kraken will be re-refined, so that Lu Feng's previous cultivation will be in vain.

"It's a mess. ”

In Lu Feng's ears, the voice of the sword spirit sounded, and the Burning Immortal Sword took the initiative to unsheath and floated on Lu Feng's knees.

"If it weren't for this sword spirit, you kid would be useless. ”

Sword Spirit Dao, the Burning Immortal Sword exuded an extraordinarily hot aura, like wisps of fire, along the pores and breath around Lu Feng's body, seeping into Lu Feng's body.

The cold and heat converged on every inch of Lu Feng's muscles and bones, allowing Lu Feng to truly experience what is called the taste of ice and fire, the flesh and blood were further refined, and there was an unbearable itching sensation from the bones, and the black filth seeped out of the body little by little.

Lu Feng could faintly feel that his physical body was becoming stronger at an incredible speed, not only his muscles and bones, but also every part and every organ of his body was being refined.

"You're willing to help. ”

Lu Feng was surprised, from the first time he came into contact with the Sword Spirit, he felt that the Sword Spirit was not satisfied with him.

The Burning Immortal Sword is one of the seven immortal swords, and it is the supreme immortal weapon of the immortal realm in the Nine Realms, and the requirements of the Burning Immortal Sword Sword Spirit for the sword master are of course extremely harsh, even if it is the top young genius in the Nine Realms, the sword spirit may not be able to look at it.

What's more, Lu Feng's martial arts talent was originally only nine grades, but after the transformation of the Burning Immortal Sword, he barely reached the fourth grade, since entering the Holy Martial Hall, his cultivation speed is in the Heavenly Xuanwu Mansion, which is definitely unprecedented, but in the martial arts world, he can only barely be regarded as a genius, and in the cultivation world, he can only be regarded as an ordinary person.

If he came to a more vast world above the cultivation world, Lu Feng's current realm and strength were not as good as a seven or eight-year-old child.

One can imagine how disappointed the sword spirit was when he saw Lu Feng.

Lu Feng thought that he would not help himself until the sword spirit recognized him as the sword master of the Burning Immortal Sword.

"Could it be that you have already recognized me as a sword master?" Lu Feng said with a smile.

Sword Spirit snorted coldly: "Don't be presumptuous, I said to give you three years, but I just won't let you die within three years, and it will be difficult for you to satisfy me after three years." ”

When he said this, Sword Spirit's view of Lu Feng had changed, in the human world, when the aura was not abundant and there was a relative lack of cultivation resources, it was extremely difficult to reach the fifth level of the foundation building period in such a short period of time, and what made the sword spirit unexpected was Lu Feng's will, which was so resolute that it was beyond the imagination of the sword spirit.

Three years is not a long time, but Lu Feng is very confident, and it won't take three years for the sword spirit to completely recognize him as the sword master of the Burning Immortal Sword.

Lu Feng looked at Xu Man, this guy trembled all over, fortunately, he had reached the sixth level of the foundation building stage, with dragon blood flowing in his body, and his physical body was far stronger than other martial artists in the sixth level of the foundation building stage.

Xu Man, who was flowing with dragon blood, even without the help of the Burning Immortal Sword, was enough to resist the ferocious medicinal properties of the Heavenly Snake Cold Pill.

After about three hours, the cold qi in the body gradually receded, and the medicinal power of the Heavenly Snake Cold Pill was perfectly absorbed by Lu Feng.

What Lu Feng has to do next is to continue the crazy cultivation of the previous few days, so that the role of the Heavenly Snake Cold Pill can be brought into full play, and then Lu Feng will not be far away from completing the bone quenching stage.

Lu Feng let out a long breath of turbidity, and at this time, the frost in the house had already melted, and the moonlight outside the house was bright and starry.

Xu Man's eyes were also opened, his expression was abnormal, he was gasping for breath, his mouth was steaming, his face was red, his muscles were bulging, and the whole person was like a small stove.

On Xu Man's forehead, two black hard objects no larger than the size of a little finger protruded, his arms were almost covered by dragon scales, and a tent was raised on his lower body.

Lu Feng's face changed, and the ferocious medicinal properties of the Heavenly Snake Cold Pill stimulated the bloodline power of the dragon's blood.

"Young Master, I'm ......"

Xu Man was speechless, and his eyes were aimed at his lower body.

Lu Feng immediately understood, the dragon nature is inherent, and he has sex with different creatures, and he doesn't know how many creatures with dragon blood have been bred in the Nine Realms, and the blood power of the dragon blood in Xu Man's body was completely stimulated by the medicinal properties of the Heavenly Snake Cold Pill, and the dragon's nature seriously affected Xu Man.

"Get up, follow me to Tiewu City!"

Lu Feng immediately decided, if this kind of thing happens, it can only be solved in Tiewu City, if you endure it all the time, the power of the dragon's blood will burn Xu Man to ashes from the inside out.

That's probably the only downside to getting Dragon's Blood.

Under the darkness of the night, Lu Feng and Xu Man left the Heavenly Xuanwu Mansion at the fastest speed and galloped across the wilderness.

Xu Man's violent wheezing was like a wind box, and a low roar came out of his mouth from time to time, and he cast the thunderous nine steps that Lu Feng gave him, as fast as thunder, not much slower than Lu Feng's extreme speed.

At this time, Xu Man's potential was stimulated to the maximum, sweating profusely, his clothes were soaked, a large amount of impurities in his body seeped out, and the blood power of the dragon's blood exploded, which was also a process of quenching his body.

"This kid is lucky, after tonight, I'm afraid I'm going to approach the threshold of the sevenfold foundation building period. Lu Feng said secretly in his heart.

The sword spirit said, "The dragon blood in his body is the purest demon dragon blood. ”
