Although Daqin's steel and glass technology have been developed for seven or eight years, it is okay to make some daily necessities such as pots, pans, bowls, saucers, teacups, etc., and there is no problem with complex things such as gear bearings and bolts, it is still not enough to make particularly precise things.

The hydraulic press that Chen Xu has developed for many years has not been successful yet. Because of the insufficient precision and poor sealing, it is made a specious hydraulic press, which emits oil everywhere when used, and it is completely inconsistent with commercial standards.

Although the syringe has a simple structure, it has higher accuracy requirements. It not only cannot leak water, but also cannot leak air. Because it is made of glass, it is countless times more difficult to polish after forming than steel. It is considered successful if you can get one of the ten syringes that can barely pump water.

The most difficult thing is not the syringe, but the needle.

According to Chen Xu's design requirements, it is necessary to use steel to create a fine needle tube that is almost the thickness of a boar bristle. This difficulty cannot be described in words. Ma Gan and a group of craftsmen have endured for many days and nights and how many brain cells have been killed, but they are still helpless about this amazing project. So after these years, Chen Xu has not been inquired about it on weekdays. He knew that once the factory succeeded, the factory would ask for merit and receive rewards. However, this time, it was done quietly while he was not paying attention.

"Mr. Marquis, I've brought the syringe!" A priest came over with an enamel box, with water inside, and a pair of syringes soaked in the water.

If you only look at the appearance from a distance, Chen Xu will suddenly feel that this is a pair of glass syringes that are common in later generations. In the past, they were often seen in rural clinics. After using them, they were boiled and disinfected, and then used repeatedly. Chen Xu was familiar with this. He was originally in the second grandfather's pharmacy, and he had stolen it out to play with it.

But now when he held the syringe in his hand, he grinned and felt a little black in front of him. Forget the syringe, it was just that. But the needle in front was thicker than a toothpick, and it could be seen that the needle was carefully polished, sharp and four inches long, and the black needle hole in the middle made people feel cold in their hearts.

Imagine the feeling of this needle pricking on the butt, Chen Xu couldn't help but shivering and his anus shrank tightly.

Chen Xu took the first syringe in human history, which was probably usable, and then tried to twitch the syringe. The sound of an old cow drinking water sounded. In an instant, the water in the enamel box spiraled down and disappeared. The syringe with an inch diameter was sucked in full swing. Chen Xu raised it and pushed it gently, and a stream of water shot out like a fountain for more than a meter away.

"I know why the monkey goes crazy..."

Chen Xu murmured and sighed, putting the syringe into the enamel box.

Zheng Boqiao and a group of alchemists looked at each other one by one.

"My Lord said that this syringe cannot be used?" A priest couldn't help but speak.

"It can be used, but it's too rough. The needle is too thick and too long. And how much potion did you use to experiment with monkeys just now?" Chen Xu said with a thrust.

"It's probably a tube!" A priest answered a little hesitantly.

Chen Xu looked at the huge syringe that could be about three or four taels again, and prayed for the monkey in his heart.

Fortunately, I beat it to death, otherwise I would have gone crazy until I finally lost my strength and died.

The effect of the Five Poisons Soul-Suppressing Water is unquestionable. Drinking it directly can boost the soul and strongly stimulate the body's potential, especially it has great effect on boosting men's heroism.

But this ancient Miao prescription with inexplicable origins uses poisons after all. Although Chen Xu knew that this was a good thing and was definitely a blessing for the majority of male compatriots, the side effects were too obvious. If the side effects cannot be significantly reduced or the components that stimulate desires were removed, this kind of drug can only be classified as poison, and cannot be released openly, and it cannot bring realistic effects.

It has been seven years since Chen Xu first obtained the formula, and the Five Poison Shuhun Water has been developed one after another with the continuous research and improvement of a group of medical priests such as Zheng Boqiao.

The effects of these versions of the agents vary due to the different ingredients and quantities of various poisons. Generally speaking, several of them have met the standards for medical use in Chen Xu's opinion. As long as they are not used in excessive amounts, the side effects are not obvious. Therefore, in the beginning of spring, Chen Xu asked Li Gui to bring Zheng Boqiao and several alchemists who participated in the research of improved formulas back to Xianyang from the mountains of Qianzhong, and brought back a large amount of potions to continue to study in the Nanshan Villa.

When he learned from Yu Wuya that Gai Nie might have a hard time, Chen Xu asked the glass factory to make a batch of crystal bottles, specially customized some exquisite wooden boxes, filled a few boxes, and specially brought one box on his body, preparing to go to Langya and ask someone to take them to Yingzhou to give them to Gai Nie, but unexpectedly he met them in advance on the sea, so he made a favor.

Seven times a night is not the biggest reason why Chen Xu is interested in the Five Poisons Shuhun Water, but Chen Xu feels that this magical poison can be developed into a first aid drug like a heart-enhancing needle, used on battlefields and critical moments.

When he left Xianyang for inspection, Chen Xu had already instructed Li Gui that once the Qinghe Hospital was successfully built, the laboratory would be transferred to the hospital. First, this would be concealed, and second, it would be able to purchase a lot of medicinal materials openly. Using animals such as monkeys and rabbits for experiments is also an important part of the health center's knowledge of drug tests and anatomy. Whether it is successful or failure, it will not arouse people's doubts.

After Chen Xu came back this time, he visited this secret laboratory several times, but the drug test did not make much progress, and the syringe was not manufactured, so the injection effect naturally could not be verified.

Chen Xu's purpose today is very clear, that is, he feels that time is getting more and more urgent. If there are some major historical time that cannot be completely changed, then the First Emperor will be closer to his death. This is what Chen Xu doesn't want to see. He needs to be thoroughly prepared. If the improved injection version of the Five Poisons Shuhun Water can work, it may be useful at the most critical moment.

The so-called luck is just a missed or obtained an opportunity that is enough to change your destiny at the right time and place.

Chen Xu felt that he had reversed so much history of the Qin Dynasty. Maybe at the last moment, he could also reverse Qin Dada's fate. Even if it lasted for one year and a half or even a few days, it would be enough to change the future of the Qin Dynasty.

Today, he seemed to be lucky, and he got the news that the syringe was successful.

Today, it seems that the monkey has a relatively lucky life and dies under his pistol.

This is the rule of fate under complex causal entanglement.

Every drink and peck all changed in the dark.

In the following time, Chen Xu asked in detail about the experiments with monkeys, and then again strictly reminded him to abide by the laboratory rules and regulations, and let a group of alchemists adopt a stricter sanitation system and drug production process. Whether it is distillation and purification or dissolving solvents, try not to contact the outside air. After all, these potions will be injected into the human body in the end, and a little bit of viruses and bacteria may cause more serious consequences.

It is said that developing drugs costs money and time-consuming, but Chen Xu finally has a personal experience now.

The Five Poisons Shuhun Water has been studying for seven years since its discovery. During these seven years, Chen Xu has invested millions of money in nearly 100 people, and it has spent millions of money to build this secret laboratory, but it has not yet achieved the result he wants, and he is now feeling more and more unable to delay.

He urgently needs something that can reverse life and death in a critical moment, and in the future, he will have more confidence and confidence in the face of the nine-year disaster that Guiguzi mentioned.

Whether for himself or the First Emperor, the Five Poisons Shuhun Water is the most effective means he can control.

In order to speed up the development of the drug, Chen Xu had to spend more time and energy to urge a group of alchemists to spend more money to purchase various experimental equipment and live experimental materials. He even called Vice President Fang Sheng to the laboratory and gave him a secret task, which was to find a large number of endangered and dying patients for clinical trials.

Although this practice is immoral, just like later pharmaceutical manufacturers and some patients sign new drug trials, this does not violate the law, and is also an indispensable part of the process of verifying the efficacy of the drug. It is just that things are urgent and Chen Xu rarely takes into account the patient's right to know. In this era, if you are seriously ill, it is basically a dead end. Although this kind of experiment has unpredictable consequences, it also has an opportunity to prolong life, and patients and hospitals all take what they need.

In the next few days, Chen Xu, in addition to attending court and handling some urgent and important government affairs, basically spent every day in Qinghe Hospital. In addition to watching and guiding a group of alchemists to purify and configure the medicine strictly in accordance with the rules and regulations, he also summoned Ma Gan and Tang Ting, the two chief officials in charge of the machinery factory and the glass factory, to watch a group of alchemists give an injection to a dog. Seeing a big yellow dog bulging a big bag on his thigh after taking an injection, jumping wildly and wailing, both of them braved cold sweat and went back to improve and develop syringes.

Three months, this is the longest time Chen Xu gave them.

Within three months, a small, convenient and qualified syringe must be developed, otherwise Chen Xu would inject such a large syringe potion into their butts.

During these days, Qinghe Hospital has successfully found several patients who are in critical condition, including serious illnesses, severely injured and dying, and one is a pregnant woman with difficult labor. Chen Xu asked Fang Sheng to drink the oral version of the Five Poison Shuhun Water to patients who can still take oral, and to inject the Five Poison Shuhun Water for injection to patients who have not been given the medicine. The effect is also good and bad. Overall, the oral version is safer and more effective than the injectable version.

After the pregnant woman who was ill-produced with a bottle of potion, she quickly recovered her strength and successfully gave birth to a daughter with the help of a group of doctors in obstetrics and gynecology. Although the pregnant woman fell into a coma after giving birth, her life was not in danger.

A bottle of potion successfully saved two lives, which not only excited Fang Sheng and a group of doctors, but also surprised Chen Xu. After so many years of large investment and research, he finally got a slight reward in the field of first aid.

Except for this pregnant woman with difficulty, the other clinical experiments were not particularly successful. None of them lived for two days. The two dying patients who were given injections only lived for two hours and the other lived for about eight hours.

Although the results are frustrating, they are not without gain. After taking the medicine, these two patients showed a brief state of mind and a little refreshed mental state. They could even have a simple communication with their families and medical staff. You should know that these two special patients have been bedridden at home for three or five days and have almost no movement.
