The three of them walked less than a hundred meters forward, and a narrow clearing appeared in the woods, surrounded by more than a dozen wooden sheds and some simple stilted buildings, and a small stream passed through the middle of the clearing, and some of the weeds on both sides of the stream had turned yellow and withered, apparently contaminated by chemicals and smoked to death.

An Ruizhi made a round tour of the clearing, and on both sides of the clearing were simple watchtowers built on large trees, on which people were patrolling the surrounding forest, and they could see the mount of general-purpose heavy machine guns.

After seeing them come in, a middle-aged man ran towards Gao Yuanqu, "Hello eldest son, do you have any instructions?" ”

Gao Yuanqu waved his hand, "I'll accompany two friends to come over and have a casual look, you can go on your own, I will call you if you have something." After speaking, he led An Ruizhi to an open house made of wooden planks, and the surrounding area of the wooden house was steaming hot, and there was a pungent smell.

When the three of them walked into the open wooden house, they saw three large iron pots in the middle, and in each iron pot there was a large iron bucket, and in the iron pot was boiling hot water, and the iron bucket was also steaming outward, as if something was boiling.

Next to each iron bucket stood a young man with a top body, holding a wooden stick in his hand and stirring in the iron bucket, although everyone was already sweating, they kept shaking the wooden stick.

The people working inside greeted him with a smile when they saw Gao Yuanqu coming in, it seemed that they all knew this young owner. Gao Yuanqu waved his hand at them, signaling them not to stop what they were doing.

An Ruizhi approached the large iron pot and looked into the iron bucket, which was tumbling with a viscous liquid, thick, black like Chinese medicine juice, and there was an indescribable strange smell.

At this time, a man walked to the iron bucket, and saw him holding a thermometer in his hand and inserting it into three iron buckets for testing, which seemed to be a technician.

An Ruizhi asked Gao Yuanqu softly, "Master Gao, what are they doing?" ”

"This is the first procedure for the production of Chinese white." Gao Yuanqu pointed sideways to a corner of the wooden house, where there was a pile of black things the size of a basketball, and continued, "First cut those raw tobacco paste into small pieces, and then throw them into an iron bucket to heat and melt them. Because the water temperature should not exceed 85 degrees when dissolving opium, otherwise the quality of the product will be affected, so this method of heating over water is used. ”

An Ruizhi nodded, he couldn't imagine that the conditions and methods of their drug production were so primitive and simple, who would have thought that heroin, which was higher than the price of gold, was produced in such a humble environment.

At this time, the person who had just measured the temperature poured a large bowl full of white into the iron bucket, and then gestured to the person who was stirring, signaling him to speed up the stirring.

Gao Yuanqu approached An Ruizhi and said: "What is added to the iron bucket is quicklime, which decomposes the opium solution into morphine and less caine, and when the opium solution is milky, there is no need to stir it again." Other alkaloids, calcium sulfate, and insoluble substances in the opium liquid precipitate to the bottom of the barrel. Wait for the solution to turn pale brown, and then filter it out. The filtered opium liquid must be reheated slightly as before, and then stirred with a certain proportion of ammonium chloride. Ammonium chloride crystallizes and precipitates morphine, and then filtered by the sand cloth, the morphine is separated from the solution...... "Maybe I can't stand the strange smell and high temperature inside, Gao Yuanqu said this and motioned An Ruizhi to go out."

There was a raging fire under the three cauldrons, and the steam coming out of the pot made the cabin at least forty degrees hot, and after staying in it for a few minutes, the clothes of the three people were soaked with sweat.

After the three of them came out, they stood in the open space to cool down a little, and then walked to another wooden house, Gao Yuanqu said to An Ruizhi as he walked: "This is the place where the morphine is purified, and the morphine refined for the first time is gray-yellow, because it is not pure, it still contains some cocaine." When this morphine is pressed into lumps, it is yellow arsenic, and about 10 kilograms of raw opium can be refined into about 1 kilogram of morphine. ”

As they spoke, they went into the hut, which was much cleaner than the one before, with two men in white coats busy, and in the middle of the room there was a workbench made of wooden boards, on which were some glassware and some chemicals, and on one side of the room there was a dryer.

Gao Yuanqu introduced to An Ruizhi: "Here is the second step of the whole production, add a certain proportion of acetone to the morphine just refined, then stir evenly, let the mixture automatically play a chemical role, and then filter the solution with filter paper, and then dry it to get morphine with a color of snow white and a purity of more than 99%. ”

As he spoke, Gao Yuanqu picked up a white rectangular cube and handed it to An Ruizhi, "This is the processed white block, and the three nines on it represent its purity." ”

An Ruizhi took it in his hand and weighed it, weighing two kilograms, and asked Gao Yuanqu, "Next, use this as a raw material to produce heroin?" ”

"Yes, this is just the production of white blocks, our third step of production is concentrated in a secret cave, the white pieces are remade into heroin is the most high-tech step in the entire production process, and special technicians are needed to operate, today is a little late, I will take you to see it when I have time."

An Ruizhi guessed that they kept the production and storage of heroin secret, and they would definitely not take themselves to such an important place before their identity was still suspicious, and today Gao Yuanqu took them to see these are very ordinary processes, and through this incident, it can be seen that Gao Kan is still wary of himself.

When the three of them returned to the cottage, the people in the market had dispersed, just as Gao Yuanqu said, the local people who came to the street late and dispersed early.

An Ruizhi and Fang Puheng returned to the stilted building where they lived, and there were already soldiers who brought them rice, the staple food was rice, and there were four dishes, fried cured meat, stewed pheasant, mountain mushroom soup and a plate of green vegetables.

After the orderlies left, the two began to devour their meals, and after a morning of running the mountain road, tired and hungry.

Wise whispered to Fang Puheng while eating: "Take the time to touch the cave where they produce heroin, and if you have the opportunity in the future, you will blow it up." ”

"Didn't Gao Yuanqu say that he would take us to see it in the future?" Fang Puheng asked softly.

"They can't take us until they have cleared their suspicions about us, Gokan is a suspicious man, don't look at us if we saved him, this guy is still wary of us."

"Well, this guy looks at us differently after returning to the cottage, so we really have to be careful."

An Ruizhi pondered for a moment and then said, "Our next focus is to find a way to go to the old city, and finding out the situation of the Lang brothers is the top priority. ”
