Thoughts wander for a moment.

Li Hao already had an idea in his heart.

A few days later.

Li Hao came to the dock with a large amount of money.

At present, because of the fall of the gang leader and the helmsman, many people are looking for their own way out.

The boats that originally belonged to the water conservancy gang were divided into pieces and controlled separately after they were ventilated.

Every boat truly belongs to the people on board.

Without the Water Conservancy Gang, there are not so many twists and turns in their respective transactions.

Li Hao casually found a merchant ship whose captain was practicing blood, paid a deposit, and asked him to buy a large amount of medicinal herbs.

Of course, in order to deter, Li Hao still showed his strength in front of the public.

Of course, this strength was only controlled at the early stage of the Blood Coagulation Realm.

There is no way, if you open a medical clinic in a strange place, if you don't show your strength, you will be in trouble at that time.

Even so, although the Blood Condensation Realm was not top-notch in Jiangbo Town, at least no one dared to provoke it.

A lot of things will be much easier.

Just opened a medical center, and did not touch the interests of too many people.

Buy a plaque from the bookstore in Jiangbo Town.

On the left, may there be no sickness in the world.

On the right, it is better to have medicine and dust on the shelf.

There is no other meaning, the main purpose of his medical clinic is to raise silkworms.

Treating diseases or something is mainly used as an excuse to buy a large number of medicinal materials.

The pharmacy can be compared to strangers, and the hidden point where a large number of medicinal materials are purchased all year round.

Moreover, during the treatment period, through the understanding of the human body, the cultivation plan of the wire silkworm can be adjusted little by little.

The human body is too mysterious, there is not too much material, and Li Hao does not dare to try it rashly.

What he had done before was the path that the martial arts ancestors of this world had taken, so he didn't have much to worry about.

Now he is deducing forward, taking a road that no one has walked, then he can only explore the human body and conduct experiments.

A plaque was hung in front of the front yard gate.

All kinds of medicine cabinets and chairs needed for the medical hall are also ready.

Indeed, after showing some strength, there are indeed no bull ghosts and snakes looking for any trouble.

Even, because of the dissolution of the Water Conservancy Gang, many people are expanding their power and preparing to become the second Water Conservancy Gang, and they have thrown a lot of branches for powerful people.

These were all rejected by Li Hao one by one.

The grievances and grievances of the rivers and lakes, where is it easy to raise silkworms.

In this way, a medical clinic called "Qingyun" opened in Jiangbo Town.

On the opening day, no one came to congratulate them.

No way, Li Hao is not familiar with the townspeople here when he first arrives, and he doesn't have much expectations for seeing a doctor in the early stage.

The position of a doctor is the result of years of fame.

In the previous medical hall, the eldest lady's character was not good, but the treatment method was really nothing.

Otherwise, with his style, he would have known how many times he had been beaten to death with a stick if something went wrong.

No one came for more than ten days, and Li Hao was not in a hurry, and safely transported a large number of medicinal materials from the boat and fed the wire silkworms.

During this time, what is more interesting is that the orthophonic insect was born.

In the wing, looking at the puddle of mucus pulled out by the wire silkworm, the corners of Li Hao's mouth were slightly hooked, and he gently took out the worm in the mucus with the wire, which was as slender as a hair.

There is only one orthophonic worm, but it is not impossible to breed.

It is almost the same as the cultivation of wire silkworms, and only needs to cut off the reproductive organs, like grafting trees, and plant them in the grooves of wire silkworms.

The main ability of the wire female silkworm, in addition to spinning silk, is to devour the reproductive organs of male silkworms and use them for reproduction.

In the process of matching the orthophonic insects, except for the reproductive organs, which were a little difficult to find, Li Hao searched for more than ten days before cutting off a little bit, everything else was fine.

The successful cultivation of the orthophonic insect means that the protective measures of the entire courtyard have been upgraded to a higher level.

In just half a month, dozens of orthophonic insects were cultivated.

Li Hao stored them in all corners of the entire courtyard.

And he carried a large amount of negative sound worm iron poured with wire silkworm liquid.

As long as someone sneaks into the courtyard, the sound insect will amplify the other person's voice infinitely, forming ultrasound.

This ultrasound will not be detected at all unless it is in direct contact with the orthophonic insects.

But negative sound insects are different, negative sound insects can absorb surrounding sounds, plus when Li Hao pours iron with wire silkworm liquid.

Engrave a spiral pattern next to the only hole in the iron block.

The spiral pattern was burned by the way he made his own record player.

It will only receive the ultrasound waves of the orthotonic insects, thus reducing the ultrasound waves to a normal volume indefinitely.

When the two insects cancel each other out, the voice of the person who intrudes into the courtyard will be in his ears.

And vice versa, what Li Hao said will also be infinitely reduced by the negative sound worm, infinitely amplified by the positive sound worm, and finally transmitted intact.

The two work together to act like a biophone.

It's just that this kind of biological phone has a distance limit, and there is no way to get out of the range of positive and negative sound worm sound vibrations.

Li Hao tested it with the iron block, and the straight-line distance that they could propagate to each other was about a kilometer.

If you store positive and negative sound worms along the road, you can also expand the range all the way.

That's what Li Hao did.

There was no one in the pharmacy either, and he was at sunset, in the dead of night, with a large number of negative sound insects hanging on his body, wandering around Jiangbo Town.

The positive and negative sound insects are planted three meters below the ground according to the pre-calculated plan.

In this way, as long as there is any disturbance in the medical hall, he can return as soon as possible.

Even if you can't go back, it's fine.

He has already put the cultivation of wire silkworms and other silkworms into the ground.

That's right, it's underground.

Now, the front yard should have become a medical hall, even if the backyard has all kinds of protection, Li Hao still feels uneasy.

Don't be afraid of 10,000, just in case.

Therefore, he stripped his whole body and secretly made holes over and over again.

Fortunately, he used the sound worm to quench the spine dragon day and night, and added the wire silkworm as nourishment.

A body of qi and blood can be said to be endless.

In just two or three days, it opened up more than 20 meters underground, and expanded the space several times, which was much larger than the area of the courtyard on the ground.

Li Hao, who was underground, carrying items, noticed that the iron hanging on his belt vibrated and made a sound.

Knowing that someone had come to the medical hall, he put down the wooden box full of thousands of wire silkworms in his hand.

Facing the towering and straight tunnel entrance, the qi and blood under his feet were like rockets erupting, and he jumped to the ground in a few big jumps.

"Is it a doctor?"

At the entrance of the medical hall, an old man in old cloth looked timidly at the black hole and the lack of light in the hall.

He looked down again at his clothes covered in mud caused by farm work, and he didn't dare to step forward for a while.

"Well, I am, please come in."

Li Hao crossed the backyard, came to the infirmary, and invited the old man in.

"No, no, I'm just here to ask, here I listen to the villagers ask, how much is the auscultation?"
