Rong Chengjin glimpsed through the light of the lightning whiskers that this secret room was more than two zhang high and about a few zhang wide, and the roof was transparent, as if it was made of a huge crystal stone with a thickness of one foot, and the lightning in the sky could be clearly seen.

In the center of the chamber hung a large circular iron cage made of steel bars with a diameter of nine feet and hundreds of fingers, and the inside of the iron cage seemed to be wrapped in a spherical transparent glass. Looking at the lightning, you can extend the top of the iron cage to the outside, and the steel bar more than one foot high standing on the roof can be seen clearly.

The tail end of the iron pillar, pierced into the crystal ball in the iron cage, thunder and lightning from time to time hit the steel bar standing on the roof, blooming dazzling light, the iron pillar will lead the thunder and lightning into the crystal ball, emitting dazzling light, like there are countless golden snakes rushing, silver dragons swimming, criss-crossing, erratic.

Rong Chengjin was surprised and surprised, watched it for a long time, didn't know why, only heard Kun Buduo say: "Go in!"

Rong Chengjin came back to his senses, hurriedly agreed to the word "yes", and pushed Kun Buduo into the room.

Kumbudor reached out and lit the oil lamp on the wall, and then pulled the mechanism, sealing the stone door. In a moment, the interior is bright.

I only heard Kunbudo say: "This is the secret room where I sent to practice the Five Thunder Heart Method, and no outsiders can enter it unless I am a disciple of this sect, do you see this iron cage hanging on the roof?"

Rong Chengjin nodded.

"There is an iron pillar more than one zhang long at the top of it, straight to the roof, embedded in the crystal ball in the iron cage for no reason, can connect the ten thousand thunderbolts in the air into the crystal ball, the crystal in the iron cage is ten million times better than the crystal texture of the roof, it is a thousand years of crystal excavated by my ancestors in the past years led by several people in the ground. They absorb the essence of heaven and earth under the ground, and can transform the thunder and lightning in the air.

It's just that good things are never easy to get, and if you want to be able to practice the world's best martial arts at your fingertips, you have to pay a price, the first is that you must endure hardships in order to become a master. To practice the Five Thunder Mind Method, you need to enter this crystal ball and endure the pain of the lightning scorching, the torment of the true qi running and flowing in the body, and the painful taste of going to hell and being punished by death.

If the practitioner is not able to keep the spirit of oneness, in this crystal ball of infinite energy, once he fails, his whole body will burst and die, turning into a cloud of blood mist;

Rong Chengjin replied categorically without thinking: "As long as I can practice peerless martial arts and avenge my parents, I am not afraid of going up the knife mountain and getting off the oil pot!"

Kun Buduo nodded and said, "Okay, you have backbone! It's a pity that there is no Concubine Ming to help you reconcile yin and yang, and you need to practice Wanjun thunder and lightning alone." You stand up, I will help you initiate, cross your cultivation, open the acupuncture points of the whole body, and pass on your five thunder heart methods and the acupuncture points of true qi transformation and transportation, I said you follow along, rush the pulse with internal force, and move with my true qi.

You listen well: the three yangs enter the yin, the six veins return to the heart, the qi contains the dantian, the breath is even, the three yin of the hand, from the chest to the hand, the three yang of the hand, from the hand to the head, the three yang of the foot, from the head to the foot, the three yin of the foot, from the foot to the abdomen. Yin and yang intersect, such as a ring without end; Hand Taiyin Lung Eleven Acupoints, Zhongfu Yunmen Tianfu Jue.

Xia Bai Qi Zekong is the most existing, and the column is missing through the canal and is too far away. There are few merchants such as leek leaves, and there are twenty-two holes on the left and right. This once started in Zhongfu, and finally became less business. The pulse starts in the middle of the heart, the lower part of the large intestine, and also follows the appetite, and the upper diaphragm belongs to the lungs. From the lungs out of the armpits, follow the inner line of the inner line of the less yin heart before the main body, in the lower elbow, follow the upper bone of the arm, enter the inch, go to the fish, and follow the fish out of the big finger end.

Its branches, from the back of the wrist column missing acupoints, straight out of the second finger inside the end of the end, hand Yang Ming. More qi and less blood, note this when Yin; hand Yang Ming acupoint from Shangyang two and three Hegu Zangyang Creek is long. The lower and lower hands are three miles, and the elbow of the curved pool is five miles near. The arms and shoulders are huge bones, Tianding is connected to the slur, and the quintile next to the nose is fragrant.

This once started in the shopping mall and ended in the incense. Its veins start from the end of the second finger of the big finger, between the two bones of the valley on the finger, between the two tendons, on the arm, on the elbow, on the front of the elbow, on the shoulder, before the gill bone, up out of the column bone, down into the missing basin, the end of the lungs, the lower diaphragm, belongs to the large intestine; This meridian has a lot of qi and blood, and when the qi and blood are injected into this, it is the friend of the Taiyin ......"

Kumbu Duo said in one line in his mouth, and one line of luck fingers was like the wind and slapped the acupuncture points on Rong Chengjin's body with his true qi in the air.

Wherever Kun Buduo's fingers went, Rong Chengjin's true qi was unimpeded, and even the previous passes that could not be broken through were immediately passed by Kun Buduo's hands. The whole body is warm, like a spring breeze, like a spring bath, indescribably comfortable.

Rong Chengjin was enjoying himself, when he suddenly felt that Kunbu Duo's fingers paused slightly, and then slapped down on the three acupoints of the Wind, Tinggong, and Tinghui, but it was a cloud of cold air that invaded the acupoints, which was very different from the previous feeling of being warm as the sun.

It took Kun Buduo a long time to open up all the fourteen meridians and seven hundred and twenty acupuncture points of Rong Chengjin's body.

I only heard Khumbuddo say, "Alright!" and reached out to pull the button on the wall, only to hear a soft "squeak", and the iron cage had been separated in half with the crystal, and slowly landed on the ground.

"Take off your clothes, sit cross-legged on the crystal, and I'll send you up!"

Rong Chengjin couldn't help but be stunned when he heard this, and he was puzzled, stunned on the spot, and refused to do anything.

Khumbuddo said: "The crystal ball contains infinite energy, you must remove all the clothes before entering!

Rong Chengjin listened, and then he understood. After a slight hesitation, Shu Shu untied his shirt, walked to the crystal ball and sat down cross-legged.

Khumbuddh instructed: "Remember, have one thought in your heart, no form and no self, and do not distract your mind!"

"Yes!"

Kumbudor nodded and pressed the mechanism on the wall, and the iron cage with the crystal slowly closed together, airtight.

In an instant, a bolt of lightning pierced the night sky and hit the iron pillar on the roof, and in an instant, the light in the crystal ball shone brightly, like countless silver snakes winding away.

Rong Chengjin sat cross-legged in the crystal ball, the spiritual platform was clear, his heart was free of distracting thoughts, he silently recited the heart formula, and carried the true bearing of the heavy building, with yin and yang. In a moment, I only felt that every inch of my skin was like being cut by a knife and burned all over my body, from head to toe, from inside to outside; it was like thousands of ants were constantly biting together on the skin, liver and gallbladder, intestines, blood vessels, and bones; and it was like thousands of sharp daggers running around the whole body, internal organs, and blood vessels.

Rong Chengjin has been prepared in his heart, he has put life and death aside, although he is extremely uncomfortable, he only treats it as if it is not his own, and always has a thought in his heart not to make his spirit collapse.

At first, Rong Chengjin sat cross-legged at the bottom, after half a pillar of incense, Rong Chengjin was far from the air, gradually getting higher and higher, and after a stick of incense, between Rong Chengjin's breath, there seemed to be a flash of light. Later, I saw that the white light contained in Rong Chengjin's abdomen became brighter and brighter, and gradually spread to the surroundings, all over the body, exuding dazzling light all over the body, like a pearl placed next to the lamp, dazzling.

Later, I saw that Rong Chengjin was surrounded by a cloud of colorful light, like a transparent blister wrapping Rong Chengjin in it, and the thunder and lightning were wrapped around the light cluster, and it could no longer penetrate into the light cluster.

Kun Buduo was overjoyed, knowing that Rong Chengjin had already passed the calamity and was gradually getting better, and he would soon be able to practice the Five Thunder Heart Method.

It was still raining in the sky, and lightning bolts were channeled into the crystal ball from time to time, and the infinite energy was gradually absorbed by Rong Chengjin.

An hour later, the glow was as bright as a pearl.

When Kumbuddo saw it, his eyes were filled with tears, his whole body trembled with excitement, and he said in a trembling voice: "Forty years, forty years, finally waiting for this day!"

Kunbudo pulled the mechanism on the wall to open the iron cage, and shouted, "Stinky boy, come out, congratulations on your cultivation of divine skills!"

Rong Chengjin opened his eyes slowly, flashing out of lightning, his heart turned at will, and he slowly fell down like a feather, floating out of the iron cage.
