The villain powerful minister pitted his tech house

Chapter 127 Self-produced and self-sufficient
They all said that they were worried, so they made a phone call.

In this ancient civilized world, it is quite difficult to make a telephone. Song Shushu set his sights on the earliest communication method in the earth civilization period - the telegraph.

This is a technology that uses electricity to transmit information at high speed over long distances since the generation of alternating current.

The principle of the telegraph is very simple. When the current flows through the wire representing a certain letter, it will charge the ball that was trained with it first, and the latter will then ring a small bell and emit the note corresponding to the letter.

To make a telegraph is to learn from others. The biggest technical difficulty is to create other efficient codes that are suitable for Xia Guo and can replace Morse codes.

With a new goal, Song Shushu was full of enthusiasm, and began to study what kind of code could replace Morse code day and night.

On the other side, Song Ruishan, who was far away at Jialin Pass, also couldn't sleep at night.At this time, he was standing on the tall city tower, looking at the enemy camp in the distance through the natural danger.

"General, we are running out of food and grass." His generals reported to him, "If we don't collect food from the city, the soldiers will start eating grass roots."

"Just wait." Song Ruishan stood in the harsh night wind and said calmly.

Everyone knows that the people in the pass only have a good harvest, and now is the time when they have the most food in a year.But these foods will support today in the coming year.

Song Ruishan would not confiscate their things unless it was absolutely necessary.

Song Ruishan frowned tightly, and the seriousness on his face could not be melted away for a long time.

Just when the soldiers below had no choice but to look in and look at the people in the pass, someone outside delivered food.

"General! Some people have brought food and grass!" Outside the barracks, soldiers cheered excitedly.

Song Ruishan hurried out to see that bags of freshly dried rice were neatly stacked on the wooden cart, he untied one bag, grabbed a few and knocked them in his mouth, full and crisp, with a strong rice fragrance, this year new rice.

Song Ruishan smiled, "Okay, who sent this?"

"Second Miss, it was sent by Second Miss Song!" The escort replied.

"It's actually Second Miss!"

The soldiers next to me were amazed, "Second Miss knows that we are short of food, why are you so punctual, that's great!"

Song Ruishan was also very surprised, but at the same time he couldn't help but feel a little proud. He turned around and bragged to his subordinates, "That's right, I don't want to see whose child this is."

"By the way, Second Miss Song asked me to bring this to the general, please send it to General Song Yi." The visitor handed over the red amulet in his arms to Song Ruishan.

Song Ruishan, who had the same amulet hanging around his neck, twitched and quickly put it in his arms.

Thinking of Song Yi, and looking at the soldiers below, Song Ruishan's originally relaxed brows gradually frowned again.

It's time to find a way to contact Song Yi.

It is better to ask for yourself than for others.

They have to do it themselves to defeat Chengjun...

##
Every three days, Song Shushu went to the Prime Minister's Mansion on time.

There is not always news about border crossings.

Sometimes when there is no news, Song Shushu can only eat and drink at Fu Xuan's mansion.

After all, everyone is acquaintances and has no feelings, but Song Shushu's thick skin can't stand it.

Fu Xuan sat upright on the wooden chair, watched Song Shushu finish eating the lychees specially given to him by the emperor, and put down the teacup in his hand, "You come here every three days to eat and drink, don't you know how to bring something in return?"
