Later, the Drinking Snow Building, a holy place for martial arts, was hit by lightning and caught fire.Most of the martial arts masterpiece "Yan Ruzhen Sutra" was burned.The remaining fragments gradually disappeared again.Ten years later, few people know the Yanru True Scripture anymore.This book has even been denounced by many conservative ignorant warriors as a work of deception.However, all this did not have any effect on Yang Fei.In the depths of his memory, a whole set of "Yan Ruzhen Sutra" is engraved.Although Yang Fei's memory is missing, most of the martial arts knowledge has become a part of his consciousness.In the past few days, Yang Fei has been cultivating martial arts wholeheartedly, and has gradually developed the Ren pulse and the Du pulse.And his qi and blood gradually flowed between the Ren and Du pulses, forming a simple circulation.However, it is still quite difficult to return the qi and blood of the whole body to the sea and incorporate it into the sea of qi in the lower abdomen.The dantian of the human body, also known as the sea of qi, is the most important and mysterious place in the human body.The sea of qi of ordinary people is only the size of a grain of rice, and it has almost no effect on the condensation of qi and blood throughout the body.A master of cultivating martial arts, the essence of the whole body is extremely powerful, but he can use the essence to open up the sea of qi and gradually expand.Opening up the sea of qi is the most important first step in the knot, but it is also extremely dangerous.The essence of the human body, like the water of the Yellow River, has great power.This incomparably violent force, if it rushes into the sea of qi, it must be filled with the sea of qi.The cause of death of many senior great masters was sudden diarrhea.This is actually because he failed to open up the sea of qi, and he was broken by the qi of the essence and died.Therefore, before the martial artist can get married, he needs to open up the sea of qi little by little.Then, slowly incorporate the qi and blood and essence qi to expand the qi sea little by little.This process must not be in a hurry.Once the knot is successful, the qi and blood of the whole body are condensed at one point and slowly warmed.In the end, the quantitative change turned into a qualitative change, mixed with impure qi, blood, and essence, and finally all became Dan Jin.The power of pure Dan Jin Yuan Qi is more than ten times more than that of Qi and Blood Essence Qi.A powerful force that can form an invisible force similar to a magnetic field.This is the unique martial arts force field of Dan Jin masters.The stronger the Dan Jin Vitality of the Dan Jin master, the stronger the martial arts force field.A master of cultivating martial arts, only after he has truly become a Dan, can he be regarded as a peerless master.The human body itself will begin to evolve for the third time after being tempered and nourished by the vitality of Dan Jin.The master of Yudan's success is no longer a mortal, and is respected as a god by ordinary people.In history, there are countless predecessors of the gods, such as Bodhidharma Patriarch, Wudang Zhang Zhenren, leaving many magical legends.A master of transforming strength like Yang Fei can actually challenge a master of Danjin, but it is really because of the Nine Extremes Exercise, which is too against the sky.Of course, this also has to do with the fact that this guy is proficient in firearms.As long as he has a gun in hand, don't say that he is a master of Danjin.Even a higher-level martial arts master can't escape without being left behind.It's not that Yang Fei is powerful, it's that modern civilization technology is too powerful.For several nights in a row, Yang Fei ran the Turtle Twilight Heart Method.He was dense and dense, mobilizing the qi and blood in his body and impacting the sea of qi.It's like a miner mining underground.With each pickaxe, a piece of coal was dug up, and the hole grew a little bigger.Every time Yang Fei ran Zhou Tian, the dantian qi sea widened a little bit with difficulty and slowly.It's just that this widening is negligible, about one thousandth the size of a grain of rice.After a day and night, the sea of qi opened up was almost imperceptible.However, even so, Yang Fei was not discouraged.The larger the sea of qi is opened, the more Dan Jin Yuan Qi can be contained.And the greater its own strength.In order to get married as soon as possible, Yang Fei asked Chen Ke for leave and pushed away all the chores.He spent the whole day cultivating in his hut.The other women didn't know what he was doing, ignored him, and went about their jobs.And every day, Crazy Knife called Yang Fei at a fixed time to report to him the changes in Yannan's underground world.What surprised Yang Fei and Crazy Dao was.Since that day, Yang Fei has sniped and killed the two great masters of Sang Kingdom.For more than a week, I actually spent it peacefully, and the days were not shocking.Yang Fei was still cultivating hard and bravely.He is like a chrysalis wrapped in a cocoon, breaking free from the shackles of his body little by little, hoping to turn into a colorful butterfly.A late night after seven days of retreat.In the Dragon Garden Villa, a long howl suddenly sounded.The voice is like a dragon's roar, like a tiger's roar, piercing through gold and cracking stones, and the wind and clouds change color.At the same time, it was accompanied by an indescribable awe-inspiring divine might.And with this long roar, a mighty and impenetrable aura filled the entire Longyuan Villa.Koharuko in the yard is holding her tail in fear.It hid in the kennel, whining and shaking.And the rest of the sleeping people also felt fear from their sleep.Everyone curled up in a ball.Strangely, no one woke up from their deep sleep.The instinct of living beings to seek advantage and avoid harm makes everyone unconsciously hide in the room, as if to avoid natural disasters.In Yang Fei's room, he sat cross-legged with an irrepressible look of surprise on his face.His sea of qi has finally opened up successfully.This also means that Yang Fei has succeeded.What surprised Yang Fei was.As soon as his qi sea was opened, the scale greatly exceeded that of ordinary Dan Jin masters.The sea of Qi of the Dan Jin master, with each person's talent, the practice of the exercises is different, and it is also different.Ordinary Dan Jin masters, when the sea of qi has just opened up, it would be good to have the size of a cherry.Even if the cultivation realm is improved in the later stage and the sea of qi is further opened, it is only the size of a wine cup.However, Yang Fei's sea of qi has just opened up and is the size of a wine cup.This is already equivalent to the sea of qi of the peak master of Dan Jin Tianpin.This meant that Yang Fei was able to convert more of the Essence Yuan Qi into Dan Yuan Qi and store it in the Qi Sea.The huge Dan Yuan Qi not only means more powerful power.Moreover, it also means that the body evolves faster, and the speed of cultivation is also faster.Yang Fei stood in the middle of the room in a daze, unable to hold back tears.Ever since the evil dragon had an accident and he was injured.The martial arts kung fu he lost was finally regained.Moreover, he finally broke through Danjin.Since then, the world is so big, and there is invincible capital.Although Yang Fei's current strength still can't compete with the Alliance of the Gods.However, it is definitely not easy for any of the main gods of the Alliance of Gods to kill themselves.And in the Heavenly Demon Alliance, in addition to the mysterious Demon Emperor.The three demon kings, if they want to deal with the Lanting Group, they have to ask their fists first.Yang Fei thought in his heart, running the four-pole heart method, and wanted to see the effect of the four-pole heart method.Among the tiger poles, the tiger thorn and tiger roar are more powerful.And the tiger and Yang Fei's divine majesty are even more powerful.After the knot, Yang Fei's mind was clearer.The speed of the turtle pole is twice as fast.Even if you are beaten by the Kung Fu Turtle Shield, the defense value is even stronger.The power of the elephant pole has increased dramatically, and the power of the elephant shock has become even stronger.The power of the seven shocks became eight.This was something Yang Fei did not expect.The snake sting was silent, the breath was more hidden, and the snake devouring and scale shock were further enhanced.After the knot, Yang Fei's combat power became unprecedentedly strong.
