Ye Xing rode a horse and accompanied the herald to the foot of a Hujiao Mountain hundreds of miles away, and the special training team surrounded them, and everyone called them the helpers and let them into the mountain.

As soon as he sat down, without any hesitation, Ye Xing asked everyone to report the situation immediately.

Now here, there are 3 squads with 120 people as the backbone, and 630 bandits with relatively effective combat effectiveness have been recruited.

Now basically 2 people lead 10 people to form a team, and they are all training these days.

The personnel did not die, some were wounded, but they were dealt with, the bandit leaders who did not surrender have been killed, and those who surrendered are now scattered and integrated into the army.

Ye Xing asked a few leaders who had surrendered to come over, took a closer look, and then asked them to go back.

Ye Xingdao, "One has the strength of the 8th layer of the day after tomorrow, and the rest also have the strength of the 7th layer, so they may not be sincere, but don't be afraid, I will keep an eye on it." ”

After a pause, Ye Xing asked everyone to do a good job of reorganization training, "We must let people from different forces mix with each other, and the team members are not allowed to come from the same forces." Let our people be the captains and vice-captains, and all of them will be trained according to our requirements. ”

The people were ordered to go out, each taking care of his own task.

Ye Xing called Ye Qingyan and asked him to talk about some things about fighting with the troops.

Ye Qingyan reported the details of the battles he followed the team, and said, "This kind of actual combat is really completely different, our combat power has basically advanced to the 7th layer, and during this time, we are the captain ourselves, which is not the same as before." ”

Ye Xing called the person in charge, who was the chief of staff Li Yishan, who had outstanding achievements among the cadets of the military academy, so he was elected as the head of this unit.

Li Yishan's combat power is not high, and he is still the appearance of the 6th floor, but his mind is very flexible, and he has great experience in commanding operations, and he is by no means a rough person.

Ye Xing asked him to sit down, and called four more instructors to drink tea together.

Ye Xing asked, "Now there are two bandits left, how do you want to deal with it?" ”

Li Yishan replied, "We are still reorganized, and we don't know about the situation of these two forces, and of course others don't know about us, but we are still the original bandits in Hujiao Mountain." ”

"Liang Zhihong's Osmanthus Peak is the same, only a few days before us. To deal with the two big bandits, only to break each one, not to let them unite. ”

Ye Xing pointed to the map hanging on the wall, "Neither of you has the ability to eat any force. Hujiao Mountain and Osmanthus Peak are hundreds of miles apart, how to cooperate? Now you can solve the problem of mutual communication immediately, and you can't run back and forth on horseback. ”

Li Yishan nodded in agreement, "We are engaged in carrier pigeons, or flying eagles to communicate, but this requires a long time of training, and there is no good way for a while." ”

He turned his head and asked, "Instructors, may I ask how we communicate when we are hundreds of miles apart?" ”

An elderly white-headed instructor said, "In the past, they were all beacons, fast horses, carrier pigeons, and flying eagles, and if there was no better way, they would gather somewhere after an agreed date." ”

Ye Xing thought for a while, in the era of no telecommunications, communication is really a problem. Flying Eagle, I have a pair in my Star Villa, well, it should be big in the past few months, maybe you can use it.

Ye Xing let everyone leave, sat down and thought by himself, hundreds of miles, only radio communication can convey information immediately, then only telegraph can do it.

The principle is very simple, that is, the transmitter, the receiver, the same radio frequency, as long as the signal transmission power is large enough, the signal can definitely be transmitted hundreds of miles away.

Ye Xing called Ye Qingyan and asked him to ride back to the oil base, escort a batch of oil back to Donghai City with the ship, bring a letter to Lin Tie, and also ask Li Yishan to send a letter to Guihuafeng, first reorganize the army, strengthen training, and the method will be according to their original training plan for the time being.

Then Ye Xing came to the warehouse in Hujiao Mountain, and carefully checked what there was, where all the later loot was stored, all of which were unsorted and stacked in a mess.

Ye Xing called a team of people to sort them out, and it took two days to refresh a lot, at least he could find something.

This warehouse was originally a stone cave, and there are still traces of various excavations around it, and Hujiao Mountain is the place where ore is produced.

There are many kinds of ores produced here, and many of them are now piled up, and some of them have been looted from other places, and there are many gold and silver treasures, as well as a large number of various unknown miscellaneous items.

Now Ye Xing wants to find some materials to make batteries, and the batteries are acid plus electrodes, which he knows.

He wanted to find ores for the preparation of strong acids from the superficial chemical knowledge he had learned before, and his memory was excellent, recalling them one by one, but he couldn't read the knowledge he entered with quantum intelligence later.

Or from the very faint memory, find some descriptions, now is to try.

Sulfur, pyrite, alum, chlorite, rutile, bluestone...... These ores were all discovered, Ye Xing identified them one by one, and then took some back.

He made some tools improvised, such as glass bottles, and then began to try, the main method was to make sulfuric acid from sulfur, and after several days of hard work, he finally made dilute sulfuric acid, and then heated and concentrated.

Ye Xing knew that there was a kind of battery called lead sulfate, not how, but only trying. After 10 days of experimentation, we finally made a battery stored in a glass bottle. In order to be afraid of breaking, there was no plastic, so I had to make a square box out of wood to hold the square double small-mouth glass bottles.

Ye Xing also made a simple generator, wound it into a coil with copper wire, found a natural magnet, and after repeated tests and debugging day and night, he made a hand-cranked generator that can charge the battery, although it is extremely simple, but everything is ready.

Using natural magnets, copper wires are wound into iron rods, electromagnets are made, and simple telegraphs are made to send and receive information, and the signal transmission is expressed by unequal on-off times, and the reception is recorded by punching holes in the simple paper.

Ye Xing himself conducted a simple test in the room, it was not ideal, it was too rough, and he had to keep improving.

In the end, 15 days later, Ye Qingyan returned to Hujiao Mountain with 8 little boys from Yunhai Village, and also brought a pair of big birds, and also brought Ye Xing Microscope.

These 8 teenagers were selected from among the children in Yunhai Village at the request of Ye Xing, and they were more clever, and they were only 12 years old.

Let Ye Qingyan train the two birds, hoping that they can be used to transmit information as soon as possible.

Ye Xing handed over the transmitter and receiver to 8 people, and first explained the principles and methods of work, so that they can start to improve it now, and be sure to achieve long-distance transmission and reception in a short time;

The main thing is the antenna of transmission and reception and the strength of the signal, these two aspects are carried out, so that they can boldly disassemble and improve.

Ye Xing asked Li Yishan to fully cooperate with the 8 children, meet any requirements, and let him send a number of absolutely reliable personnel to collect intelligence;

Mainly staring, the bandits of Heifeng Mountain two hundred miles away and the largest water gang in Xijiang, the White Dragon Society, each have a scale of more than 1,000, and it is also the final decisive battle of this sweeping work.

Ye Xing's main job is to carry out signal encoding work, that is, 4 states of different speeds, slowness, lengths, 6 bits permutations and combinations to represent different words, and under the simple combination, thousands of words can be expressed.

Ye Xing took the official customized dictionary of the Song Kingdom, and then began to write the code, because this work cannot be done with the help of anyone, so he can only come by himself, Ye Xing buried himself in work, and there was no day and night at all.

Ye Xing also took the time to use a variety of ores and charcoal for high-temperature melting to make alloys, high-strength alloys, made 4 connected unequal time difference switches, and handed over 8 people as a new transmitter switch, and numbered each switch with a red pen, so that you can send different 4 kinds of signals when you click the switch.

The combination of 4 signals can make up thousands of signal codes, so that the meaning can be expressed.

After receiving the signal, the receiver sends out the signal and translates it with reference to the code book, and remote communication is realized.

The principle of transmitter and receiver is very simple, but for the 8 children who have no foundation at all, they do not need to understand any knowledge, they just keep improving the test, testing and improving, constantly dismantling it destructively, and then start again.

There are only a few parts, just constantly experimenting with new parts, 8 people will have dozens of ideas every day, and then try and improve, of course, every idea must be recorded.

Every few days, there are some improvements to the transmitter and receiver, even if it is just some appearance improvements, Ye Xing does not hesitate to praise and praise.
