Outside Luoyang City, Liu Wei, accompanied by Guan Qing, led a team of dragoon guards to the village where they had first arrived.

The ridge was filled with villagers from nearby villages, both men and women, with their necks stretched out and looking out into the fields.

In the field, more than a dozen men lined up, spraying inky black potions on crop leaves with clay pots.

The potion has an inky black color, but it doesn't have a pungent smell.

Watching the men spray the potion, Liu Wei's brows were always tightly wrinkled.

arranged for Hua Tuo to configure the poison, and Liu Wei only had an attitude of trying, and did not dare to expect that the poison would really have an effect on the insects that gnawed at the crops.

Having lived in the era after 2,000 years, Liu Wei also knew the ingredients of many pesticides, but those ingredients were understood by him in chemical programs, and in the late Han Dynasty, when he did not know what the chemistry of the Dao was at all, he had no conditions to configure those pesticides that could effectively control pests, and could only hope that the medicine configured by Hua Tuo could play a role.

The black liquid was sprayed on the crops, and everyone present looked full of nervousness.

As the men walked past a field and then to the next one, Liu Wei turned his head and muttered to one of the dragoons behind him.

Seeing Liu Wei muttering, the dragoon guard quickly ran down the ridge, squatted next to a green seedling that had just been sprayed with medicine, gently opened the green seedling, glanced inside, and then turned his head to look at Liu Wei and shook his head.

"Go and invite Mr. Hua Tuo!" Seeing that the dragoon guard shook his head, Liu Wei's brows gradually twisted, and he gave an order to the other dragoon.

After Liu Wei's order, the dragon rider responded with his fists clenched, turned around and ran towards the path, and after a short time, he rode along the road towards Luoyang City.

The men were still spraying medicine in the field, looking at the backs of the men, the look on Liu Bian's face became more and more solemn.

Drugs are of little use, and they are almost a foregone conclusion. The reason why he didn't stop the men's spraying action was just because he didn't want to disappoint the onlookers too early.

After about two teas, the dragoon guards who returned to the city to look for Hua Tuo led Hua Tuo and several accompanying Luoyang cavalry to the path near Liu Bian.

Jumping off the mount, Hua Tuo didn't dare to delay for a moment, and ran quickly towards Liu Wei along the ridge.

The ridge is too narrow, although Hua Tuo used to practice medicine everywhere in the past, he also walked through many ridges, after all, he was not very fast at that time.

Now running fast on the ridges, there have been several times when Hua Tuo almost stepped on the air and fell into the field on the side.

"Your Highness!" When Liu Wei approached, Hua Tuo clasped his fists and bowed, first saluted Liu Wei, and then asked in a low voice: "But the medicinal juice is not effective?" ”

"Hmm!" Turning his head to look at Hua Tuo, Liu Wei nodded, and said to Hua Tuo in the same low voice: "The medicinal juice is indeed useless, does Mr. know why?" ”

Knowing that the medicinal juice was useless, Hua Tuo once again clenched his fists and arched at Liu Wei, and then strode to the field, opened a green seedling that had been eaten to the point of being broken, and carefully observed the insects crawling in the green seedling.

Looking at the insects that seemed to be unaffected after spraying the medicinal juice, Hua Tuo's brows frowned slightly, and after a while, he stood up, turned his head to look at Liu Wei on the ridge, and asked Liu Wei: "Your Highness, can you allow your subordinates to see what kind of equipment is sprayed with medicinal juice?" ”

Nodding towards Hua Tuo, Liu Wei turned his head and whispered a command to one of the dragoons behind him.

The dragoon guard answered, and ran along the ridge to chase after the men who were carrying clay pots to spray medicinal juice.

After a while, the dragoon guard caught up with the group of men, took the clay pot from one of them, and returned to Liu Wei's side.

The dragoon guard did not hand the clay pot to Liu Wei, but raised his hands high above his head and bowed down to Hua Tuo, who was still standing in the field.

Taking the clay pot handed by the dragoon, Hua Tuo first shook the clay pot in his hand, and found that there was still some medicinal juice in it, so he squatted down, pushed away a green seedling that had been infested by insects, and slowly put a few drops of medicinal liquid into it.

The medicinal juice dripped on the body of the insects, and many insects immediately fluttered their wings and flew up when the medicinal juice dripped down, and a few insects did not have time to fly away and were dripping with the medicinal juice.

Squatting next to the green seedlings, carefully watching the insects that were dripping with the medicinal juice, after a while, Hua Tuo put the clay pot on the ground, stood up and pointed to the green seedlings, turned his head and said to Liu Wei: "Your Highness, please look!" ”

Hearing that Hua Tuo wanted him to come forward to watch, Liu Wei hurriedly jumped off the ridge, walked to Hua Tuo's side, and bent down to look at the green seedlings dripping with medicinal juice.

A handful of insects that were still crawling in the seedlings before were now not moving, apparently poisoned by the medicinal juice.

"Seems to be useful." Looking at the handful of poisoned insects, Liu Wei straightened up, stared at Hua Tuo with both eyes, and asked him, "But why spray, but it's useless?" ”

"The subordinate has also thought about it on the road!" Clenched his fists and bowed, and saluted Liu Bian, Hua Tuo said to Liu Bian: "Poison can indeed poison insects, but it has not been effective before, maybe the amount of medicine is too small, or it may not be sprayed on the insects. ”

"Hmm!" Looking down at the green seedlings that had been poisoned by insects, Liu Wei nodded, didn't make a sound, strode and jumped on the ridge, and after going up the ridge, he said to a dragoon officer: "Tell the villagers, don't panic, there is a way to cure the insects!" ”

"No!" The dragoon guard officer responded with a fist clenched, and watched Liu Wei lead Guan Qing and a group of dragoon guards towards the path, before shouting to the villagers present: "Fellow villagers, Your Highness wants you not to be anxious, there is already a way to cure insects!" ”

The villagers who had been watching the men spraying the medicinal juice, full of apprehension, although they did not dare to jump off the ridge to see the insects in the green seedlings, a few of them were active, but they had already seen from Liu Wei's action of calling Hua Tuo here that the medicinal juice did not have much effect on the insects.

The villagers, whose mood had gradually changed from anticipation to apprehension, heard the dragoon guard officer shouting like this, and they were about to lose hope, and they were suddenly lit up again, and they all turned around and knelt down in the direction of Liu Wei's departure.

Seeing that poison can really poison insects, Liu Wei, who has more confidence in controlling insect pests, did not turn around this time to let the villagers stand up.

When he reached the side of the road, he turned over and jumped on his horse, and shouted to the people who followed him, "Go back to the city!" ”

With Liu Wei's order, Guan Qing, Hua Tuo, and a group of dragoon guards and Luoyang cavalry who accompanied the escort shook the reins and rode towards Luoyang City.

As soon as he entered Luoyang City, Liu Wei pulled the reins, stopped the war horse, and said to a dragoon guard officer behind him: "Invite one hundred and ten potters in the city to the palace, and the king has something to entrust them to do!" ”

Although he didn't know why Liu Wei suddenly thought of inviting the potter to the palace, the dragoon guard officer didn't dare to ask more, so he hurriedly answered, urged the war horse, and trotted to the street where the pottery workshops were most concentrated in the city.

Since the seedlings were affected by the disaster, Liu Wei has been going out of the city to the fields almost every day to have a look. The people in the city had long been accustomed to his comings and goings, and when they saw Liu Wei leading the guards into the city again, the people on the street hurriedly stepped aside and made way for Liu Bian.

The people did not kneel, which was also why Liu Wei asked people to post notices in the city, telling the people that when they saw him, the king of Luoyang, they did not need to kneel to greet him.

Although this move made Liu Wei not as powerful as the nobles in other places when passing through the streets of the city, it made him bring the hearts of the people closer to him.

Seeing Liu Wei lead a team of men and horses to march towards the palace, an old man whispered to the old woman beside him: "The king of Luoyang has been working all day because of the disaster of Qingmiao, if we and other small people can share more sorrow for him, it would be great!" ”

"yes!" Looking at Liu Wei's back gradually disappearing on the street, the old woman sighed lightly and said to the old man who spoke: "For the sake of me and other small people, the king of Luoyang is heartbroken!" ”

"It is also a blessing for us to be under the rule of such a good king!" The old man nodded, first sighed, then turned his head to look at the old woman, and asked her in a low voice: "A few days ago, I said that my girl is going to marry the commander of the Luoyang Army, is there any news?" ”

"Our girl is still a little handsome!" Hearing that she asked about her daughter's relatives, the old woman sighed lightly and whispered to the old man: "It's just that many families inside and outside the city want to get married in the military, and I don't know what it is, I'm afraid I still have to stuff some money for the matchmaker!" ”

"Hmmm! It doesn't hurt to spend a little more! Pulling the old woman's wrist, the old man first looked to the side vigilantly, and saw that no one was paying attention to him, so he lowered his voice and said to the old woman: "If you can climb the Luoyang Army, you and I will have a lot of face in the future, but I don't dare to feel sorry for those money and miss my daughter's life!" ”

It is no wonder that the old man was so cautious when he said this, the officers and soldiers of the Luoyang Army, under the governance of Liu Wei, not only were their salaries much higher than those of the officers and soldiers under the command of other princes, but even their military appearance was not comparable to that of ordinary princes.

Now not only Luoyang City, but in the areas under Liu Wei's rule, ordinary people have the idea of marrying the girl in their family to Luoyang Army.

Although the Luoyang army has a large number of people, compared with the many ordinary people, the number of officers and soldiers in the army is far from enough to meet all the people who have young women in their families.

It is precisely because of this that many people are proud to recruit Luoyang officers and soldiers as sons-in-law.

For Liu Wei, these are not important matters at all, the officers and soldiers of Luoyang are in demand among the people, and it is also a manifestation of the people's love for the army, and he will never interfere in such matters.

At present, the most important thing for him is to keep the Huns out of the border before Yulin and Tiger Ben Erwei have absolute combat power; The second is to stabilize Yuan Shu so as not to start a war on two fronts.

Another important thing is to control the pest as soon as possible, so that the particles do not fall out in the fall.
