Schneider seemed to realize something, "The whole army stopped moving forward, stop moving forward!" The signal soldiers immediately hung the stop flag, and the tugboat immediately hung a cable behind to escape the danger.

Guijiang was only a few hundred meters away from the city wall of Wuzhou and was within the range of the Red Barbarian cannons. The Ming army on the city immediately seized this opportunity to fire at the stranded gunboat. The iron projectiles roared and flew everywhere, causing water to splash on the river. For a moment, the situation was critical. Schneider immediately ordered the 130mm cannon on the Pearl River to bombard the Ming army's firepower. After collapsed several enemy platforms on the city wall, he finally suppressed the enemy's firepower.

The 621 paddlewheel tug carefully towed away the stranded gunboat. The gunboat that had already entered Guijiang also retreated to avoid stranding again.

It is obviously impossible to enter Guijiang again. Before the army arrived, even if it rushed in with the artillery fire on the city wall, it would have no meaning to bomb the Ming army. Schneider ordered the fleet to withdraw from Guijiang and wait for the arrival of the main force of the army.

At this time, the units of the First Mixed Brigade participating in the Wuzhou Battle had successively arrived at the boundary of Wuzhou by transport ships and landed on Changzhou Island southwest of Wuzhou City.

Zhu Mingxia sent two companies to sweep the villages and villages on Changzhou Island along the river bank south and north of the island, clearing the stubborn villages on Changzhou Island, and at the same time recruiting manpower as a "reasonable burden". Zhu Mingxia planned to set up a logistics warehouse on the island, build outposts and artillery towers to prevent the Ming army that might bring assistance from western Guizhou, and monitor the Xunjiang River.

Among the three major water systems of the Pearl River, the Xijiang River system has the largest basin and the most tributaries. Most rivers in Guangxi are tributaries or main streams of the Xijiang River system. Therefore, controlling the Xijiang River system is equivalent to controlling Guangxi. Of course, to control the huge Xijiang River water system, the scale of the Xijiang River Detachment of the Pearl River Task Force is far from enough. At present, we can only be satisfied with controlling Wuzhou, a key location for water surface transportation.

Originally, Schneider was planning to take down Wuzhou with a "cannon and charge" - he had fought many such sieges along the way - judging from the current situation, the Ming army also learned from their mistakes and would never come out to "fight wildly" with them, let alone the "water battle" of eggs hitting stones.

In this way, the battle entered the old routine of "fortification", "fireworks" and "fire attacks". One of the main tasks of the Navy under Wuzhou City was to provide fire support.

Throughout the day, the First Brigade and the Western Detachment were busy building fortifications under Wuzhou City, collecting supplies, and preparing for siege battles. The Navy pulled six artillery boats one by one to the city of Wuzhou City, and the 280mm mortar cannon on it played a great role in the outbreak of the Pearl River Estuary. Although the blasting bombs fired by the 280mm mortar cannon were loaded with high-density black gunpowder, their destructive power was enough to destroy most of the fortifications in this time and space - even if it was not blown up, violent explosions and a large number of explosive debris could shake the defenders and flee.

At the same time, the Ming army was busy on the city wall. The scouts of the First Brigade infiltrated the mountainous areas around Wuzhou and used telescopes to observe the city on the mountain. They noticed that the Ming army was busy not to strengthen the garrison, but more as if they were transporting something. A large number of straw bags were transported to the city gate, as if they were to block the city gate.

In this way, both sides spent a busy day. At night, both Fubo and Ming dynasties lit a large number of bonfires to prevent the enemy from launching night attacks.

In the middle of the night, the captain of Boat No. 42, Lieutenant Cao Dachuan, was woken up by his sailors, and said sleepyly: "What happened?" The sailor couldn't explain what was going on, but replied: "The lights on the south wall of Wuzhou City were flickering and dimming, a little strange." Cao Dachuan thought it was something big, but he was woken up with a bit of temper and was about to scold the sailors. Thinking about the fact that the sailors were just some new recruits who had been supplemented with his short time, he took off his temper.

"It's just lights, what's there to make a fuss about?"

"The light flashed and went out, as if it was a light signal."

"Rules?" Out of caution, Cao Dachuan climbed up, put on his military uniform, and went up the deck from the bottom cabin. Under the instructions of the sentry, he indeed saw a spot of light on the city wall.

When he saw it, Cao Dachuan immediately understood what happened to the light that flashed and disappeared, flashed, flashed, flashed, flashed... Isn't this the light signal?

The navy sails at sea, and the communication between ships depends on flags during the day, and light signals must be used in the evening and in bad weather. As a naval personnel, this is basically common sense.

This co-signal system was trained during the training of the officers' teaching team. Whether it is hand flags and flags or lighting signals, it uses a telegram code system.

However, this system is more professional after all. For most naval soldiers who are basically illiterate and can barely obtain a Class C diploma by literacy in the army, this can only be regarded as "common sense". To master it, you still need to receive special signal soldiers training.

Signal soldiers are not the job that ordinary Class C diploma holders can do, and are considered to be the "technical army" in the navy. Those who know light signals and other things have only signal soldiers on his small gunboat, except him.

It is impossible for Mingjun to know Morse codes. Only the one who can use lights to emit such signals is his own.

Someone is signaling us in the city!

This was not surprising to him. It was common for the leader to arrange spies or contacts in the enemy city. Along the way, he had seen many local "leaders" rising up. It was not surprising that Wuzhou had such an insider. These things did not fall under their jurisdiction, so there were naturally special people to take care of them.

"It doesn't matter, it must be my own person..." Cao Dachuan was halfway through his speech, and suddenly realized that the other party was using clear code!

Flash is w, flash is o, slash is s, flash is h...

Connected together is: woshigulangqinghuihua.

This is obviously the pinyin, and what the opposite side wants to say is obviously: "I am a lone wolf, please reply!"

He didn't understand what the lone wolf meant, but the four words "serious" situation came to his mind in an instant.

Cao Dachuan has been trained to know that the signals sent by such secret personnel are encrypted, and only those who master the corresponding codebook can decode them. The signals transmitted between naval ships are not encrypted, but only naval signal soldiers and officers can understand this.

Now this clear signal indicates that the sender has no clear recipient, but is sent to the entire Fubo Army. The sender can only expect someone to see and understand this signal.

This is a big deal. Is this signal true or false? Why is it sent on the city wall late at night? What is the purpose? These are all problems. However, Cao Dachuan knew that this was not something he should consider.

He ordered his subordinates to make a light to the Zhujiang River, and he would immediately report the important matter to his superiors. The light was responded and Cao Dachuan's request was approved. So Cao Dachuan carried a kerosene lamp and sat on a small boat with a sailor paddling on his forehead and headed straight towards the Zhujiang River.

He reported the incident to the officer on duty at the Pearl River Command. The officer on duty felt that the matter was extraordinary, so he immediately reported the situation to Schneider.

"Is there something wrong?" Schneider, who was woken up, looked confused. "I don't understand this either. Why don't you report to the intelligence department of the Brigade Staff to see what they said."

So the news came to the headquarters of the First Brigade on Cheung Chau Island. The staff officer on duty quickly woke up the No. 1 major figure sleeping on the Pearl River: Naval Intelligence Staff, veteran permission.

Xun arrived in Wuzhou in the evening. After several days of the boat, he was so tired that he didn't even eat when he arrived at the ground. He went straight to the vacant cabin and went to sleep. He was suddenly woken up, and Xun was naturally in a bad mood, but the news he heard made him turn angry and laugh. He didn't bother to put on his neat naval uniform and ran to the ship building in his shorts.

The purpose of the trip was to be assigned by Jiangshan to go to Wuzhou and to be in charge of the intelligence work of Guangxi, and to prepare for the next attack on Guangxi. The Foreign Intelligence Bureau does not have many networks in Guangxi, but only has intelligence personnel in a few key cities. Because these intelligence personnel are far away and have not close contact, most of them are in semi-hibernation. It is the main purpose of the permission to "activate" them as soon as possible.

He knew that there were intelligence personnel in Wuzhou City, but he did not have much expectations for what role they could play. As soon as the intelligence personnel here were "long-term lurking", mainly collecting daily political and economic intelligence, not expanding intelligence networks, unlike Zhaoqing, where secret organizations with dozens or even hundreds of people can work together to "open the city gate". Moreover, once the city gate is closed, the intelligence personnel will be unable to play a role at all. The instructions given to them by the Intelligence Bureau also asked them to "lurk down and save themselves."

At this time, the intelligence officers in the city suddenly sent a signal, which was obviously an important information transmission. Otherwise, they would not have taken such a risk.

So he allowed the order and replied with a light: "I am the center, received it!"

The opposite side obviously received a light, but replied: "There are spies in the city and ambush!"

This was a little dazed, and he immediately sent a signal to inquire: "The specific situation."

After staying in the Nanxun Gate Tower for half a night, Luo Yangming used the lampshade to open and open the lampshade to compile a Morse code to send the signal, and finally got a response. Luo Yangming had only five or five ways to convey information in this way. To a large extent, he was taking risks. Because he had no channel to transmit the emergency information he had.

To be familiar with telegram code, you need to memorize the encoding of twenty-six letters and ten numbers, and at the same time you must master the spelling of the pinyin and be able to accurately translate the telegram code. This is undoubtedly a fantasy for most naturalized civilian soldiers who are illiterate or semi-illiterate - only the communication soldiers master this technology.
