Of course, the immortal grass that Zhang Chi has picked through a lot of hard work is not Tiger Pilan, how can ordinary people with the naked eye recognize the treasures of heaven and earth?

Although Li Yuejin was short-tempered, he was cold on the outside and hot on the inside, he accompanied Zhang Chi down the mountain overnight, and accompanied him to the hospital at the foot of the mountain for an examination.

After the examination, it was found that the shoulder joint was well reduced, and no other treatment was needed at all, and the doctor's instructions were the same as the girl's. As for the other skin injuries, they are not serious, and they can go home after simple debridement.

Zhang Chi was also very grateful to Li Yuejin for his enthusiastic help, he took out 200 yuan to express his gratitude, Li Yuejin refused, not only confiscated but also returned the 75 yuan of shoe money that Zhang Chi had paid him before.

Li Yuejin admires filial piety the most, in his opinion, the little fat man Zhang Chi in order to treat his mother's illness, he did not hesitate to sacrifice his life and forget to die to venture mountaineering, and now such filial piety young people are rare.

Li Yuejin also took the initiative to send Zhang Chi to the train station and helped him catch the last train to Beichen, and even the train ticket was bought by Li Yuejin. At the time of parting, Li Yuejin hugged his fists very traditionally and said, "Take care!"

Zhang Chi only had his left hand moving freely, so he could only wave his hand: "Thank you, uncle!"

Li Yuejin was very resistant to the title of uncle: "Actually, I'm only thirty-one, not a few years older than you." "He doesn't like to be called uncle.

Thirteen is good, more than ten years.

Zhang Chi said with a smile: "Thank you, Brother Li, you have time to come to Beichen to play with me!" he said casually out of politeness.

Li Yuejin nodded solemnly and said, "Zhang Chi, go back and take good care of your mother, say hello to her old man for me, and in a few days, I will visit her." ”

Zhang Chi was a little confused when he heard this, shouldn't he be serious? Looking at Li Yuejin's serious expression again, it was clear that he was making a promise, Zhang Chi was a little dizzy, Grandpa Mao said that he was afraid of the word serious in the world, and I understand it a little now.

If Li Yuejin really went to Beichen to visit his mother, who had died a long time ago, would this guy go crazy after discovering the truth, and even beat himself up?

Zhang Chi believes that this possibility exists, and it is very likely. He shook Li Yuejin's calloused and powerful hand with his intact left hand and said, "Brother Li, you are also busy, don't delay your work." ”

Li Yuejin swore solemnly: "I will definitely go." ”

Zhang Daxian's scalp tightened, he let go of Li Yuejin's hand, coughed dryly and said, "Brother Li, I'm leaving." ”

He turned around and walked towards the ticket gate, and Li Yuejin's sworn voice came from behind him: "Zhang Chi, have a good trip, I will definitely go!"

Zhang Daxian hated to whip his mouth with his backhand, why did I owe it so much.

Even if the lie is revealed, it will be a matter of the future, maybe Li Yuejin will soon forget about it, after boarding the return train, the little panic in his heart will soon be replaced by the joy of this trip.

This was destined to be a sleepless night for Zhang Chi, and after a lot of hardships, he finally collected the 99 materials used to refine Pei Yuan Dan.

In the dead of night, Zhang Chi sat alone in the small room, surrounded by bottles and jars, as if he had returned to the old days when he burned fire and alchemy in Tushi Palace. The biggest difference is not in heaven and earth, but in the past, he was alchemizing for Taishang Laojun, and now he is fighting for his own survival.

He can't wait any longer, life is too short, the night is long and there are many dreams, and if he waits any longer, he will GAME OVER.

Zhang Daxian took a deep breath, counted the materials and tools again with his freely moving left arm, and after confirming that they were correct, he recited in a deep voice: "Life must be alchemy, don't make the furnace empty to the moon!"

The creature put on sunglasses, turned on the butane spray gun, and first heated the pre-separated part rich in pure gold, and the flame temperature of the butane spray gun could reach 1500 °C.

According to Zhang Chi's past experience as an alchemy boy in Tushi Palace, the temperature at which the Samadhi True Fire in the Fire Source Stone is excited is usually 1000 °C.

Heaven and the mortal world do not have a unified standard of weights and measures, so Zhang Chi is more based on experience and intuition, an experienced alchemy boy can see different temperatures according to different fire colors.

Zhang Chi has been working in Tushi Palace for 800 years, and he once personally fanned the flames and tried to refine the Monkey King in the Qiankun Bagua Furnace, and his experience in burning the fire and holding the stove is extremely rich.

The flame of the alcohol blowtorch was aimed at the asbestos net, and the fire source stone was lying quietly on the asbestos net at this moment, and it had been five minutes, and there was still no change in the fire source stone. After all, heaven and earth are different, and whether or not the true fire of samadhi can be triggered can only be created by chance.

Zhang Chi began to feel a little apprehensive, if he couldn't trigger the Samadhi True Fire in the Fire Source Stone, even if he collected all the materials, he would still not be able to open the furnace for alchemy, and his efforts for many days would be in vain.

Ten minutes have passed, and it is still the same.

Fifteen minutes......

Twenty minutes......

Twenty-nine minutes......

The alcohol blowtorch lasts for between 30 minutes and 40 minutes, and if it is used for too long, the temperature of the lamp pot will continue to rise, which will cause the internal pressure of the lamp pot to be too large, and the lamp pot will be in danger of breaking.

At this moment, a layer of hazy red light appeared around the fire source stone, Zhang Chi thought that he had seen it wrong, rubbed his eyes, and the red light in the blink of an eye was even more abundant than just now, Zhang Chi realized that the samadhi true fire in the fire source stone was finally successfully activated.

He turned off the alcohol blowtorch and used stainless steel tweezers to quickly transfer the fire source stone to the bottom of the black shell green Dan furnace, the three circles on the fire source stone were like three red lights lit up, and the red light radiated by a small fire source stone had filled the entire room.

Zhang Chi added the materials prepared in advance to the Dan furnace refining room one by one, and finally added the part containing pure gold to it, which had no effect on itself, and played the role of polymedicine molding, which was equivalent to the role of adhesive, because of the lack of means to completely separate pure gold and gold, it could only be placed into it.

Although the Dan furnace is small, there is a Qiankun inside, which is divided into three parts, the bottom can be placed with the fire source stone, the largest space in the middle is used to enter the medicine and remove the slag, and the smallest part of the upper layer near the furnace cover is used to refine the Dan. Mash the dansha and medicinal herbs into the middle medicine room, close the Dan furnace, and use fire to write first and then martial arts.

Make sure that all the medicinal materials are melted, and the Dan Qi rises into the upper Dan room, and the gas condenses and condenses, and the condensation becomes the Dan. A cycle is called a section, and each section is slag removed once, and it is repeatedly refined, and the best elixir must be repeatedly refined at least nine hundred and eighty-one times, and the time span can be as long as seven seven and forty-nine days.

Pei Yuan Dan This kind of pill belongs to the most basic solid essence of the pill, naturally there is no need to refine it repeatedly, usually refining twelve knots is enough, judging from the color of the fire, the current Samadhi True Fire accumulated in the fire source stone can only support a maximum of seven hours of refining.

The mystery of the true fire of samadhi does not lie in how high the temperature of the flame is, but in the fact that it can gather all the divine fire, the essence fire, and the folk fire at the same time.

The flame turned from red to green, and from green to blue, and the blue flame burned to the fullest, and then turned into cyan, which is the so-called blue out of blue and better than blue. The cyan flame appeared in the Dan furnace, like a bud waiting to be released, and over time, this bud slowly bloomed, like a green lotus blooming in summer.

Zhang Chi sat cross-legged on the ground, looking intently at this small Dan furnace, his heart was full of desire for life, even if it was not so easy to gain a foothold in the mortal world, for him who had cut off the immortal vein, he first thought about how to live healthily, and then he could think about how to live better. You have to eat the rice one bite at a time, and you can't eat hot tofu in a hurry!

Zhang Daxian had no sleep all night!

Seven hours passed, and the twelve stages of ascension were completed, and the fire source stone returned to its original appearance, and the three circles on it were as white as jade. The Dan furnace has been cooled, and the Dan medicine in the furnace has been completed. The final link is extremely critical, and if you are a little negligent, you will lose all your efforts.

Zhang Chi opened the lid of the stove, and a pungent smell came to his face, and there was no fragrant smell of Peiyuan Dan, but a mixture of green onions and leeks.

Zhang Chi's first thought was failure, which was not right, but when he thought about his experience of riding Wuling bread, it should be the smell of green onions and leeks on the immortal grass.

The refined Pei Yuan Dan lay quietly in the Dan furnace, black and not slippery, the size of a cherry, but it was olive-shaped, and the surface was pimple and rough like bayberry.
