Seeing that Wang Tiezhu was still stunned, Li Changfeng quickly reminded: "Why are you still standing there? You can't get up and kowtow?"
Wang Tiezhu then came to his senses, and quickly got up and knelt on the ground, regardless of the gravel on the ground, and kowtowed pounding.
"Disciple, pay homage to the master!"
Wang Tiezhu is a little silly, but not stupid.
He has confirmed that the old monster is a peerless master. With such a person's teaching, his strength will definitely improve by leaps and bounds, and not everyone can have such an opportunity.
Seeing him kowtow and become a disciple, the old monster nodded slightly and said lightly: "Okay, get up, today you will be considered my closed disciple of the old man!"
Wang Tiezhu stood up, smiling silly, very happy.
Li Changfeng did not forget to remind him: "Don't forget about learning barbarian language, do you know?"
Before Wang Tiezhu could speak, the old monster glared and snorted coldly: "Boy, I have the final say in my disciple. If you don't let him practice martial arts well, what kind of barbarian language will you learn?"
Li Changfeng did not hide the old monster, and told the matter in the prison, and finally said: "Let Tiezhu learn the language of the barbarians in the future, he will be used by him as a barbarian god. This matter will not be delayed!
”
The old monster looked at Li Changfeng with great meaning and said, "Are you pretending to be a barbarian god? It's interesting, old man, I'm sure!"
The old monster was a thunderous and decisive person and immediately began to teach Wang Tiezhu. Li Changfeng felt bored and left the backyard and walked out of the mansion to see the Imperial Guard and the Great Insider.
Because there are many Li Changfeng's people in Baishi City, these people don't need to stare at him all the time and divide them into several shifts to rest.
The prosperity of Baishi City and the many ways to eat, drink and have fun make these people feel like Liu Laolao has entered the Grand View Garden, and everyone is very excited.
More than a thousand people suddenly flooded into Baishi City, and businesses of all sizes improved a lot, especially the heavens and earth were crowded. The powerful programs inside shocked them and lingered.
For a moment, Li Changfeng was a little worried about these people's money bags. I'm afraid that these people would become penniless in a few days.
It's night.
It was the third time that the wind was high and the moon was dark, and everyone was sleeping soundly, and Li Changfeng fell asleep.
A figure hidden in the darkness avoided the imperial guards and masters patrolling outside the mansion and sneaked into the city lord's mansion quietly.
Just as he had just stepped into the inner courtyard where Li Changfeng was, the old monster sitting in meditating under the pond in the backyard suddenly opened his eyes and a smile appeared on the corner of his mouth.
"This killer is really good, no wonder he can make that brat feel a headache."
After saying that, the old monster closed his eyes again.
At the same time, the killer suddenly stopped, his eyes showing an unconcealed look of horror. The originally calm state of mind, which was originally Wubo, rolled up huge waves at this moment.
A terrible aura locked him in his eyes. The feeling was that he was being targeted by a peerless beast, and he was as small as an ant.
The killer turned around and ran away without any hesitation.
When I escaped from the city lord's mansion, I felt that the terrible aura disappeared, and my heart was relieved.
"call!"
The killer let out a long sigh, his clothes were all wet.
Li Changfeng knew nothing about this and slept so comfortably until dawn.
After breakfast, Li Changfeng went to the Research Institute for inspection as usual.
As soon as he arrived at the research institute, a thin middle-aged man in a white coat and a white hat ran over with excitement.
"Your Highness, I'm about to send someone to invite you, there's good news!"
The thin middle-aged man is named Tang Yi, and he is one of the important scientific research talents in the Medical College of the Research Institute, no less than Liang Dafu.
Seeing that he was so excited, Li Changfeng asked quickly: "Can... penicillin be extracted?"
There was no antibiotic drug in this era. An ordinary wound infection could leave all so-called famous doctors helpless, and the mortality rate was astonishingly high.
After Li Changfeng came to this world, he realized the importance of this. The scientific research institute was established simultaneously at the beginning of its establishment. One of the most important scientific research projects was the development of penicillin.
Li Changfeng was not a medical student in his previous life. He only knew the general production process and purification method of penicillin, and then taught him to Tang Yi.
He hopes that Tang Yi can make penicillin to provide a guarantee for his life, and at the same time he also wants to rely on penicillin to save more lives.
Of course, the emergence of penicillin will inevitably bring him unimaginable huge wealth.
Tang Yi was originally a famous doctor. After listening to Li Changfeng's description of penicillin, he devoted all his time and energy to it.
After years of painstaking research, there are finally results today.
"Yes, we extracted mold from the corn paste, and after extraction and refining, we obtained penicillin and tested it on a calf with an inflamed wound!"
Speaking of this, Tang Yi took a deep breath, his eyes flashed with amazing spirit, and he said in a trembling voice: "As a result, the inflammation on the calf's body gradually disappeared, and now the calf's wound has scabbed and has become energetic.
!This shows that penicillin has been successfully developed!”
As a doctor, Tang Yi knew what this major discovery meant to this world, which was enough to rewrite the history of the entire world and create a myth!
"Okay! Very good! Very good!"
Li Changfeng was also very excited and patted Tang Yi on the shoulder a few times, encouraging: "Continue to research and be sure to achieve mass production as quickly as possible!"
Tang Yi shook his head and said, "Your Highness, it is still difficult to achieve mass production for a while. First of all, the penicillin we extracted is not pure enough, which shows that we still have many areas to improve in technology."
"Secondly, we have not conducted human trials so far, and are not sure whether it has such amazing effects on humans. We dare not rashly mass production before confirming this."
Li Changfeng was very satisfied with Tang Yi's rigorous scientific research attitude and nodded, "Yes, we must do human experiments first, and then mass production will be made."
Then the conversation changed and said solemnly: "I am going to fight the barbarians soon. At that time, hundreds of thousands or even millions of soldiers will charge in battle, and countless lives are waiting for penicillin to save you. Do you understand the historical mission you carry on your shoulders. Is it?"
Tang Yi instantly felt a sense of mission and said solemnly: "Don't worry, your highness, you must do your best to improve the purification technology. After confirming that there is no problem after human testing, mass production will be achieved as quickly as possible!"
Li Changfeng patted Tang Yi on the shoulder and nodded, "I believe me, come on!"
After some encouragement, Li Changfeng was in a good mood and inspected the progress of other scientific research projects and confirmed that each project was in an orderly manner before leaving.
Just as he was about to return to the city lord's mansion, a young soldier wearing armor and covered in dusty face ran over quickly and knelt on the ground.
"Your Highness, the Investigation Corps urgently reported!"
After three consecutive beast tides occurred in Baishi City within half a month, Li Changfeng felt that the matter was a little strange, so he formed an investigation team to investigate the matter.
Each soldier in these corps is an elite force, and he has been active in the dense forests outside Baishi City for a long time to investigate evil beasts, as well as pay attention to the abnormal movements of surrounding forces.
Hearing the urgent report, Li Changfeng frowned and said, "Get up and talk!"
"Report to Your Highness, a team of barbarian cavalry raided the turbulent oil field outside the city, and more than 30 oil production workers suffered casualties. Now our investigative corps is fighting the barbarian cavalry. However, the situation is dangerous if the troops are insufficient, the general will come to ask for help!"
Hearing this, Li Changfeng's face immediately darkened and he shouted angrily: "Thunder Riders gather together, put on their armor and go and kill the enemy with me!"
With the current industrial technology, it is impossible to explore underground oil fields to exploit oil, so the open-pit oil field outside the city is crucial to him.
He has sent people to search everywhere for many years and has not yet discovered a second open-pit oil field, so this oil field must not be missed!
This is the basis for his hard work in industrialization. If it is destroyed by barbarian cavalry, it will be troublesome.
"The barbarian cavalry is fierce, Your Highness cannot take risks..."
The thunder cavalry accompanied him was anxious and did not want Li Changfeng to join the battle, but he was stopped by waves: "Don't say so much, go!"
After saying that, Li Changfeng turned over the horse and grabbed the horse's belly hard.
The war horse neighed and rushed straight out of the city like lightning. Seeing this, Lei Qi quickly got on the horse and followed him out with a fierce flattery.
In an incense stick, Li Changfeng led the thunder cavalry to the vicinity of the oil field, and heard the shouts of killing from afar.
The soldiers of the Investigation Corps were fearless and fought with the satisfying soldiers riding horses to death. Everyone was already injured, some even limped, but they did not retreat at all.
There were dozens of corpses on the ground, most of which were from the Investigation Corps.
Seeing this scene, Li Changfeng was furious, and pulled out his long sword from his waist and pointed it straight at the barbarian cavalry, shouting: "Thunder Cavalry, charge!"
All the thunder riders raised the three-meter-long spear in their hands in an orderly manner, without making a sound. Everyone's eyes flashed with murderous intent, quiet and heart-pounding, like ferocious beasts rushing towards them.
The Investigation Corps and the oil collector were immediately overjoyed when they saw Li Changfeng bringing the thunder cavalry to fight.
"Your Highness is here personally leading the thunder cavalry!"
"We are saved!"
"Kill these barbarians!"
The barbarian cavalry had never fought with the Lei cavalry. Seeing that they were not large in number, they didn't care at all. When they heard that the general in charge turned out to be His Highness, they were immediately overjoyed.
"The ninth prince of Dagan is actually here!"
"Haha, whoever can win the prince's head will definitely receive a generous reward!"
"The opportunity to make contributions is right in front of you!"
All the barbarian cavalry had an amazing look in their eyes, as if they had seen the glory and wealth in front of them, and they did not take Li Changfeng seriously at all.
