Li Changfeng saw that Wang Tiezhu was still stunned, and hurriedly reminded: "What are you still doing in a daze?" Don't get up and kowtow yet? ”

Wang Tiezhu came back to his senses at this time, and quickly got up and knelt on the ground, ignoring the gravel on the ground, and kowtowed his head with a bang.

"Meet the master!"

Wang Tiezhu is a little naïve, but not stupid.

He has confirmed that the old monster is a peerless master, and with such a person to teach, his strength will definitely improve by leaps and bounds, and such an opportunity is not something that anyone can have.

Seeing him kowtow to his master, the old monster bowed slightly, and said lightly: "Okay, get up, today you will be regarded as my closed disciple of the old man!" ”

Wang Tiezhu got up, with a smile on his face, very happy.

Li Changfeng did not forget to remind: "Don't forget the matter of learning the barbarian language, you know?" ”

Without waiting for Wang Tiezhu to speak, the old monster's eyes widened, and he snorted coldly: "Stinky boy, old man, my apprentice, I have the final say, don't let him practice martial arts well, what barbarian language to learn?" ”

For the old monster, Li Changfeng didn't hide it, he told the things in the prison, and finally said: "Let Tie Zhu learn the barbarian language in the future, so that he can pretend to be a barbarian god, which will be of great use to me, and this matter must not be delayed!" ”

The old monster glanced at Li Changfeng meaningfully and said, "Pretending to be a barbarian?" It's kind of interesting, old man, I'm ready! ”

The old monster was a resolute person, and immediately began to teach Wang Tiezhu, Li Changfeng felt bored, so he left the backyard and walked out of the mansion to see the Imperial Forest Army and the master of Ouchi.

Because there were already a lot of Li Changfeng's people in Baishi City, these people didn't need to keep an eye on him all the time, and they were divided into several shifts to rest.

The prosperity of Baishi City, the variety of eating, drinking and merrymaking, makes these people have a feeling that Grandma Liu has entered the Grand View Garden, and everyone is very excited.

More than 1,000 people poured into Baishi City at once, and the business of large and small businesses was much better at once, especially in the heavens and on earth.

For a while, Li Changfeng was a little worried about these people's money bags, I was afraid that in a few days, these people would become destitute.

It's night.

At the time of the third watch, the wind was high and the moon was dark, everyone was asleep, and Li Changfeng also fell asleep.

A figure hidden in the darkness evaded the Imperial Forest Army and Ouchi masters patrolling outside the mansion, and quietly infiltrated the City Lord's Mansion.

Just as he stepped into the inner courtyard where Li Changfeng was, the old monster who was meditating under the pond in the backyard suddenly opened his eyes, and a smile appeared on the corner of his mouth.

"This killer's strength is really good, no wonder it can give that stinky boy a headache."

After saying that, the old monster closed his eyes again.

At the same time, the killer suddenly stopped, and his eyes showed a look of horror that could not be concealed, and the calm state of mind that was originally unwavering was rolling up a monstrous wave at this moment.

A terrifying aura locked on him, and the feeling was that he was being targeted by a peerless beast, and he was as small as an ant.

The killer didn't hesitate and quickly turned around and fled.

When he escaped from the City Lord's Mansion, he felt that the terrible aura disappeared, and his hanging heart was relieved.

"Whew!"

The killer let out a long breath, his clothes soaking wet.

Li Changfeng didn't know anything about this, so he slept comfortably and slept until dawn.

After breakfast, Li Changfeng went to inspect the scientific research institute as usual.

As soon as he came to the scientific research institute, a thin middle-aged man wearing a white coat and a white hat ran over with an excited face.

"Your Highness, I was about to send someone to invite you, there is good news!"

The thin middle-aged man named Tang Yi is one of the important scientific research talents of the Medical College of the Scientific Research Institute, no less than Liang Dafu.

Seeing that he was so excited, Li Changfeng hurriedly asked, "Could it be ...... Penicillin refined? ”

In this era, there are no antibiotic drugs, and an ordinary wound infection can make all the so-called famous doctors helpless, and the mortality rate is alarmingly high.

After Li Changfeng came to this world, he realized the importance of this, and at the beginning of the establishment of the scientific research institute, a medical school was established at the same time, and one of the most important scientific research projects was the development of penicillin.

Li Changfeng was not a medical major in his previous life, he only knew the general production process and purification method of penicillin, and then taught it to Tang Yi.

He hoped that Tang Yi could make penicillin to provide a guarantee for his own life, and at the same time thought of saving more lives with penicillin.

Of course, the appearance of penicillin will inevitably bring him unimaginable wealth.

Tang Yi was originally a famous doctor, and after listening to Li Changfeng's description of penicillin, he was very excited, so he put all his time and energy into it.

After years of painstaking research, the results are finally available today.

"That's right, we extracted mold from the corn paste, extracted and refined it to get penicillin, and tested it on a calf with an inflamed wound!"

Speaking of this, Tang Yi took a deep breath, his eyes flashed with an astonishing look, and the whole person trembled with excitement: "As a result, the inflammation on that calf's body gradually disappeared, and now the calf's wound has scabbed over and has become energetic!" This shows that penicillin has been successfully developed! ”

As a doctor, Tang Yi knows what this major discovery means to this world, which is enough to rewrite the history of the entire world and create a myth!

"Good! Very good! Very good! ”

Li Changfeng was also very excited, patted Tang Yi on the shoulder a few times, and encouraged: "Continue to research, and be sure to achieve mass production as soon 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 a lot to improve in technology." ”

"Secondly, we have not conducted human trials so far, and we are not sure if it has such an amazing effect on humans, so we dare not rush to mass production until we have confirmed this."

Li Changfeng was very satisfied with Tang Yi's rigorous scientific research attitude, and nodded: "Yes, we must do human trials first to confirm that there are no problems before mass production." ”

Then the conversation changed, and he said solemnly: "My great cadre and the barbarians are about to start a war, and there will be hundreds of thousands or even millions of soldiers charging into battle, and countless lives are waiting for penicillin to be saved, do you understand the historical mission on your shoulders?" ”

Tang Yi instantly burst with a sense of mission, and said very solemnly: "Your Highness, rest assured, your subordinates will go all out to improve the purification technology, and after confirming that there is no problem after human trials, mass production will be achieved at the fastest speed!" ”

Li Changfeng patted Tang Yi's shoulder and nodded: "I believe in you, come on!" ”

After some encouragement, Li Changfeng, who was in a good mood, inspected the progress of other scientific research projects and confirmed that each project was in progress in an orderly manner before leaving.

Just as he was about to return to the City Lord's Mansion, a young soldier in armor and dust on his face ran over quickly, and fell to his knees.

"Your Highness, the Survey Corps is urgent!"

At the beginning, after three consecutive beast tides appeared in Baishi City within half a month, Li Changfeng felt that something was wrong, so he formed an investigation corps to investigate the matter.

Each of these soldiers is an elite, and has been active for a long time in the dense forests and mountains outside Baishi Castle to investigate evil beasts and pay attention to the movements of surrounding forces.

Hearing that it was an urgent report, Li Changfeng frowned lightly and said, "Get up and speak!" ”

"Report to Your Highness, a hundred-man barbarian cavalry raided the fire oil field outside the city, and the oil extractors suffered more than 30 casualties, and now my investigation corps is fighting to the death with the barbarian cavalry, but the lack of troops is in danger, and the last general has come to ask for help!"

Hearing this, Li Changfeng's face immediately sank, and he shouted angrily: "Thunder cavalry assembled, put on armor and mount horses, and go with me to kill the enemy!" ”

With the current industrial technology of Daqian, there is no possibility of exploring underground oil fields to extract oil, so the open-pit oil field outside the city is very important to him.

He has been searching everywhere for many years, and he has not yet found a second open-pit oil field, so this oil field must not be missed!

This is the basis for his industrialization in Daqian, and if it is destroyed by the barbarian cavalry, it will be troublesome.

"The barbarian cavalry is fierce, Your Highness must not be in danger......"

The accompanying Lei Qi was in a hurry, not wanting Li Changfeng to participate in the battle, but was stopped by a wave of his hand: "Don't say so much, let's go!" ”

After speaking, Li Changfeng turned over and pinched the horse's belly.

The war horse neighed, and went straight out of the city like a gallop, and when Lei Qi saw this, he hurriedly got on his horse and followed him out.

As soon as the incense was burned, Li Changfeng led the thunder horses to the vicinity of the oil field, and heard the hoarse shouting of killing from a distance.

I saw that the soldiers of the Survey Corps were not afraid of death, and fought to the death with the satisfied soldiers on horses, everyone was wounded, and some even limped, but they did not flinch at all.

There were already dozens of bodies on the ground, mostly from the Survey Corps.

Seeing this scene, Li Changfeng was furious, and suddenly pulled out the long sword at his waist and pointed it directly at the barbarian cavalry, and shouted: "Thunder cavalry, charge!" ”

All the thunder riders raised their three-meter-long spears in their hands in unison, without making a sound, and everyone's eyes flashed with murderous intent, quiet and palpitating, like fierce beasts rushing towards each other.

The survey corps and the oil extractors were overjoyed when they saw Li Changfeng coming with the thunder cavalry.

"His Highness personally led the thunder cavalry here!"

"We're saved!"

"Kill these brutes!"

The barbarian cavalry had never fought with the Thunder Cavalry, and when they saw that they were not numerous, they didn't pay attention at all, and they were overjoyed when they heard that the leading general turned out to be His Royal Highness the Prince.

"The Nine Emperors of Daqian are here!"

"Haha, whoever can win the prince's head will definitely get a rich reward!"

"The opportunity to make meritorious contributions is right in front of you!"

The eyes of all the barbarian cavalry burst out with an astonishing look, as if they had seen the glory and wealth in front of them, and they didn't take Li Changfeng in their eyes at all.
