After listening to Luo Yue's speech, Ludendorff's eyes lit up, of course he knew the airplane, and now there are many factories in Germany that are developing airplanes, but Germany has more mature products than airplanes, that is, airships, invented and invested in the construction of hard airships invented and invested in the construction of Earl Zeebling of Germany has been tested in 1900, earlier than the Wright brothers' aircraft test flight time, although the test flight of the airship was crashed during landing due to poor maneuverability, but the technical maturity of the airship, the stability of the flight in the air, are far stronger than the aircraft, and Count Zeebling absorbed the lessons of the previous failure, is building the second airship, and attracted the attention of the military.

Although Ludendorff has never seen an airship, he has seen the information, and the principle of the airship is also very well understood, at least in Ludendorff's opinion, it is much more reliable than an airplane, so it is indeed a great weapon for aerial reconnaissance. After returning to China, we can urge the research and development of airships to speed up a little more.

And another weapon that interests Ludendorff is the armored train, in fact, when Ludendorff was in Germany, he knew that the People's Army had developed an armored train, and the principle of Bi Jing's weapon is not complicated, it is nothing more than adding armor to the train, at first Ludendorff only regarded the armored train as a battleship on land, that is, to move the giant cannon to the land to use, but after listening to Luo Yue talk about the battle of the Muling River, he knew that the armored train was originally used in other ways.

The winner of the Battle of the Muling River was the surprise attack of the People's Army to occupy the Muling River Railway Station. However, the Mulinghe Railway Station is about 80 kilometers away from the Suifenhe Station, the headquarters of the People's Army, which is a relatively safe distance, because under normal circumstances, even if the People's Army launches a surprise attack, it will take at least 8 hours, and it is very likely to be discovered by the Russian army on the way and take precautions, but the People's Army used armored trains and cavalry to cooperate with the breakthrough, and it only took less than 3 hours to kill the Mulinghe Station, and captured the Mulinghe Station with lightning speed, thus gaining the initiative in the battle, until the final victory of the entire campaign。

It can be said that the victory in the battle of Muling River certainly had the elements of Luo Yueji's discovery and seizure of fighters, but the armored train was also an important factor in ensuring the victory of the battle. Therefore, this meeting made Ludendorff feel that he benefited a lot, and it was indeed worth the trip, and at the same time, he also admired Luo Yue very much.

After the talks, Luo Yue set up a banquet to entertain Ludendorff and his party, and the atmosphere of the dinner was also very harmonious, and the two sides frequently raised glasses, but Ludendorff insisted on going to Harbin, and inspected the battlefield situation along the way, arrived in Harbin, and then turned south to Shenyang to join the German military observer group, which was equivalent to walking around the entire battlefield, and hoped that Luo Yue could support and assist.

Luo Yue did not refuse, but only reminded them that the Far East is not peaceful now, and there are a large number of bandits and thieves, so it is difficult to ensure the safety of the military observation team. Ludendorff smiled and said that as long as each member of the group was given a rifle, they could protect themselves. Luo Yue also laughed when he heard this, and sure enough, he was a soldier, and nodded in agreement. In fact, it is not uncommon for members of the Military Observer Corps to be killed or injured on the battlefield, after all, the bullets do not grow long, even if Ludendorff and others insist on completing their own journey, of course, they will not stop it.

The next morning, the military observation team bid farewell to Luo Yue and boarded a train to leave for Harbin, and Luo Yue also sent a platoon of troops to protect them and notify the railway stations along the way to pay attention to picking them up.

In the afternoon, Luo Yue boarded a cruiser and set off for Qingdao.

Luo Yue spent 6 days on the warship, and the total trip was 10 days, while the other troops had already arrived in Qingdao 2 days ago, and the Military Commission gave these soldiers a 5-day vacation, and the East China government had participated in the war for more than half a year, and finally returned to Qingdao, and it was time for them to go home and reunite with their families. Now all the railway lines in Shandong Province have been opened, as long as it is not a particularly avoidable area, it can be reached in one day, and active military personnel can buy train tickets at half price with certificates. Therefore, everyone can stay at home for at least 2 or 3 days.

At this time, the battle along the Yalu River had already begun, and the Japanese army launched a fierce attack on the KPA positions along a front about 30 kilometers wide, but the KPA had already built a complete defensive line, so the Japanese army did not have much effect. However, in the first three days, it was actually the Koreans who participated in the attack, and the real Japanese troops did not move. Gentaro Kodama's goal is to use the South Korean army to deplete the KPA's ammunition and test the KPA's weak links.

As a result, after three days of fierce fighting, the South Korean army lost more than 6,000 people, wounded more than 12,000 people, and lost nearly 1,000 people, and the People's Army's defense line was still impregnable, although the South Korean army was able to land on the west bank of the Yalu River, but could not establish a beachhead, so although several landings were successful, but each time under the strong fire of the People's Army, either all were killed, or retreated. Although Kodama Gentaro was so angry that he stomped his feet and beat his chest, there was no way, so Kodama Gentaro also shot and killed more than 60 Korean soldiers on the grounds of ineffective combat, all of which were withdrawn after landing.

However, this also gave Kodama Gentaro hope, because in Kodama Gentaro's view, the combat effectiveness of the Korean army is definitely inferior to that of the Japanese army, so the Korean army can attack the other side and land, and the Japanese army can do the same, and the Korean army cannot establish a beachhead, and it should be possible to replace the Japanese army. It seems that it should be the turn of the Japanese army to go into battle, and the Korean army fought for 3 days in a row, with heavy casualties and low morale, although it did not dare to disobey under the high pressure of the Japanese army, but it was obviously emotional, and it was in the third day of the battle, it was obvious that it was not able to work hard, Kodama Gentaro also knew that the South Korean army could not be blindly high-pressured, otherwise it would be easy to arouse troops, let the Japanese army fight, and strive to establish a position on the west bank of the Yalu River, and at the same time let the Korean army see the combat effectiveness of the Japanese army.

So on the 4th day, after the South Korean army launched two rounds of tentative attacks, Japan replaced the South Korean army into battle, although the Japanese army also attacked the opposite bank, but the Japanese army could not establish a beachhead, one was that the firepower of the People's Army was too intensive, and the other was that it was difficult to find suitable cover on the beachhead, so it was naturally impossible to establish a beachhead.

In fact, the strategy of the People's Army to defend the Yalu River was not to prevent the Japanese army from landing, because the width of the Yalu River was not wide, only 2 or 300 meters, so it was the best choice to put the enemy troops on the shore and annihilate them. During this time, the KPA not only laid out defensive positions, but also cut down all the trees on the beach, blew up the reef as much as possible, and did its best to flatten and fill in the trenches, so that the landing Japanese troops would not have shelters to rely on. And the beach was divided into blocks, and the distance was measured in advance.

When the enemy crossed the river, it was mainly all kinds of artillery to strike at the Japanese troops, while the defending troops only fired with Makqin machine guns, and once the Japanese troops landed, the KPA not only fired all the weapons in full force, but also fired all kinds of mortars according to the parameters that had been determined in advance, and wiped out all the Japanese troops on the shore and beach with intensive firepower.

As a result, the Japanese army suffered more than 3,000 casualties on this day's battle, and there was no progress either, and Kodama Gentaro also realized that it was not possible to fight like this, and it became the second Lushun offensive and defensive battle, which could only consume troops in vain, but now the Japanese army could not afford to spend it, and had to find another way, so he ordered to stop the attack, gather the main generals, and discuss countermeasures.

After the Japanese army stopped attacking, the military working group in Qingdao judged that it would take about 10 to 15 days to fight the offensive and defensive battle on the Yalu River before the landing operation would be carried out, and this time was just the right time for the marines to take a break.

After Luo Yue arrived in Qingdao, he did not go home directly, but first went to the Qingdao Administrative Building, where the members of the working group were waiting for him to report on his work and negotiate the landing on the Korean Peninsula. Although there is still some time before the launch of the landing, the current plans, plans, and preparations for the landing are still blank, so the time left for the East China Government is not sufficient.

Luo Yue first made a brief report to the working group on the situation in the Far Eastern Theater, and the detailed information is still being sorted out, and at the same time emphasized that bandit activities are rampant, and there is also the problem of Russian military command behind it, Luo Yue believes that in the next stage in the northeast except for Shenyang, it is unlikely that there will be large-scale battles, so curbing bandit activities should be listed as a priority, and before leaving Vladivostok, he had ordered the special forces as the core to form a bandit suppression team to be responsible for clearing and suppressing The work of reconnoitering bandits, it is just not known how effective it is.

The working group told Luo Yue that during the period of his return trip, the Far Eastern Theater had exterminated two bandit forces in accordance with the plan ordered by Luo Yue, killing more than 500 bandits and capturing more than 200 people.

It turns out that not only the Far Eastern Theater but also the bandit activities in the Northeast Theater are extremely frequent, mainly concentrated in Liaoning Province, because Liaoning is the most densely populated and economically prosperous region in the Northeast Region, and it also provides a hotbed for the emergence and activities of bandits; at present, several well-known bandits in the Northeast, such as Zhang Zuolin, Feng Linge, and Du Lisan, have bases and main areas of activity in Liaoning, so the banditry activities in the Northeast Theater are even more serious, and they are not only instructed by Russia but also by Japan, and the impact on the People's Army is also greater.

So far, in the Northeast Theater, seven railway stations have been attacked, two logistics teams have been looted, one train has been robbed, 359 people have died, 837 people have been injured, and more than 1,000 tons of materials have been lost.
