Courtyard House: Reborn in the 1940s, Starting with Killing Japanese Devils

This M2 60mm mortar has a caliber of 60mm and a barrel length of 726mm.

It has a maximum range of 1840 meters, an elevation angle between 40 and 85 degrees, and can fire up to 40 shells per minute.

With a thought, Zhao Heng produced an American 60mm mortar in his hand, which he examined closely.

The entire cannon consists of a barrel, base plate, bipod, sight, and ammunition container, all made of seamless steel tubing.

In common movies and TV shows, mortars often rely on bipods to support the barrel, forming a triangular structure to ensure stability during firing.

Zhao Heng gently stroked the cold cannon barrel and muttered to himself, "From a mathematical and physical point of view, a triangle is inherently the most stable structure."

Then, he somewhat clumsily removed the scope and bipod, and tried to reassemble the mortar, proceeding with great care in every action, afraid of making even the slightest mistake.

When the last component was precisely placed in its place, an indescribable sense of accomplishment quietly welled up in his heart.

The scene shifts again, revealing a desolate Ming mansion, with white mourning curtains hanging everywhere, exuding a deep sense of sorrow.

Minglou sported a retro slicked-back hairstyle, his hair slicked back and neatly combed. He wore a sharp suit and glasses, looking gentle and refined, with the elegant demeanor of a scholar.

At this moment, he was standing in front of his eldest sister Mingjing's portrait, kneeling on both knees, and respectfully kowtowing three times.

"Big sister, don't worry, Mingtai has now joined the revolutionary ranks and is working at the Southern Bureau," Minglou said softly to the portrait.

"Brother, a telegram from the Shaanxi Special Branch has arrived." Mingcheng said solemnly, holding a telegram in his hand, as he pushed open the study door and walked in.

Minglou slowly stood up, took the telegram, his brows furrowed instantly, and his sharp gaze swept over the contents of the telegram word by word.

The telegram read: "Cobra, Lone Shadow has gone to Shanghai to carry out the mission of eliminating the traitor Chen Moqun. You must immediately make contact with him. The contact information will be published in the Jinling Daily as a missing person notice. Burn it immediately after reading."

Minglou took a deep breath, his eyes becoming incredibly determined. He took out a lighter from his trench coat pocket and personally burned the top-secret telegram to ashes.

"Lonely Shadow? Shaanxi actually sent such a comrade..." Minglou murmured to himself.

Mingcheng pondered for a moment, then slowly said, "Should I go and inform Comrade Farmer?"

"No, absolutely not. Doing that is too risky and could easily expose our identities."

Minglou waved his hand in opposition, then instructed, "Acheng, find a suitable time to publish a missing person notice in the Jinling Daily."

Remember to use code words and cleverly conceal the code name "Lone Shadow" and the specific meeting place throughout the entire announcement.

We must be more discreet and cautious in our actions now.

In our line of work, nobody can predict whether tomorrow or an accident will come first.

Meanwhile, Mingcheng also needs to make contact with Japanese Colonel Takahashi Senbei;

On the other hand, Zhao Heng spent three consecutive days familiarizing himself with the terrain near his residence in Shanghai, especially every corner and hidden spot in the alleyways, which he knew very well.

He knew all too well that in such chaotic times, any tiny detail could be the key to life or death.

On the fourth day, Zhao Heng sat in front of a wonton noodle stall on the street, eating wonton noodles and fried dough with great relish.

A newsboy on the street carried a stack of newspapers, weaving through the crowd and shouting, "Extra! Extra!"

Japanese Colonel Takahashi Senbei successfully destroyed secret liaison points between the Kuomintang and the Communist Party in multiple locations, including Beijing, Qingdao, and Tianjin!

"Breaking News! Chen Moqun has officially assumed the position of Director of the Foreign Affairs Committee of the Wang Jingwei Puppet Government!"

Upon hearing this, Zhao Heng's eyes lit up. He put down his spoon, took out a 10-yuan note from his pocket, and called out to the newsboy, "Little friend, come here and give me a newspaper."

The newsboy quickly stepped forward and handed over the newspaper. Zhao Heng took it and decisively and quickly scanned it, extracting the key information.

He noticed the movements of Takahashi Senbei, a Japanese colonel who also served as the commander of the Shanghai Military Police Headquarters.

Chen Moqun has now completely betrayed his country and surrendered to the enemy, joining the Wang Jingwei regime and willingly becoming a henchman and accomplice of the Japanese invaders.

In the afternoon, Zhao Heng found a crucial clue in the Jinling Daily, which turned out to be a missing person notice.

The notice reads: [Seeking my younger brother, Bai Zhantai, who went missing in 1929...]

Zhao Heng had sharp eyes and immediately saw through the coded message in the notice, accurately pinpointing the time and place of the rendezvous.

To ensure the operation went perfectly, he decided to arrive at the scene an hour earlier than the agreed time—the rendezvous point was an abandoned clock factory in the west of the city, and the time was midnight.

He held his breath and skillfully avoided the Japanese patrols, making his way quietly along the dimly lit alley.

As night deepened, it was soon midnight.

In an abandoned watch factory on the western outskirts of Shanghai, the cool moonlight shines through the broken window panes, casting dappled shadows on the ground.

Zhao Heng took out the Lone Shadow Mask from the system space and put it on. Holding a Glock pistol in each hand, he carefully stepped over the broken watch parts scattered on the ground, afraid of making the slightest sound.

He approached the agreed meeting point silently, the only sound being the rustling of mice.

A moment later, Mingcheng slowly emerged from the shadows, his gaze falling on the man wearing the Lone Shadow Mask before him.

"Comrade Lone Shadow, I've long admired you. I am Cobra."

Mingcheng spoke slowly, his right hand quietly reaching behind his waist to draw his gun, his expression full of vigilance.

Zhao Heng nodded slightly, lowered his voice and replied, while slowly putting down his two pistols: "Hello, Comrade Cobra. I come from the mountain city, here on the instructions of Minister Ke Gong of the Holy Land of Northern Shaanxi."

He knew in his heart that Mingcheng in front of him was not the real Cobra, but he did not point it out on the spot. Instead, he observed the other party's reaction calmly.

Seeing Zhao Heng's actions, Ming Cheng breathed a slight sigh of relief and slowly lowered his gun: "Hello, Guying."

"Chen Moqun, this traitor, has already sided with the Japanese."

Mingcheng spoke calmly and succinctly, stating the current situation: "Based on the intelligence provided by Takahashi Senbei, we have wiped out our underground organizations in Beiping and Qingdao."

Zhao Heng frowned, his mind racing as he considered a solution. "I need to know Chen Moqun's exact address," he said in a low voice.

Mingcheng hesitated for a moment, then answered in a low voice, "Chen Moqun lives at No. 32 Avenue Joffre in the French Concession. It is a three-story Western-style house, heavily guarded by Japanese troops, with very frequent night patrols. It would be extremely difficult to sneak in."

A resolute glint flashed in Zhao Heng's eyes: "No matter how difficult it is, I will give it a try."

"Could you please get me a detailed map of the French Concession, along with a schedule of Japanese patrols?"
