When the great ship of history was about to turn into 1930, Qingdao, a beautiful port city, had already become the largest port in the Far East because of its special political and military location, both in terms of urban scale and port facilities, far exceeding Hong Kong, Dalian and even Yokohama in Japan, and its annual expenditure was also very amazing.

At night, Qingdao is as bright as ever, but it is not as dead and there is no light as people think. Away from the hustle and bustle of the day, Qingdao at night is a different scene. The urban area that has been expanded several times is still dotted with light, either from the checkpoints on the main traffic routes and a few necessary street lamps, or from the lights of cars and motorcycles, and from a distance, they echo the sparse starlight in the sky, as if they were a calm lake, reflecting the light that could no longer distinguish each other. The stars in the sky are scattered, there are bright and dark, and the light on the ground also has a difference between sparse and dense, and looking at the whole Qingdao, the brightest and densest lights at night must be the port area.

Located in the southeast of Qingdao City, the port and a series of wharves and berths have long been listed as a first-class military restricted area because of their important strategic role, and the aborigines within a radius of several kilometers have all been relocated more than ten years ago. Whenever night falls, although the lights can easily point out the targets of the enemy planes that come to attack, because there are still ships sailing into the port at night, the port authorities have no choice but to continue to open the outer harbor channel and some wharves, and the Qingdao air defense forces, radar units, and coastal guard patrol fleet are bound to be the busiest and most vigilant group every night.

"Your Majesty, these freighters, cruise ships and warships that temporarily enter the port are usually docked in the outer harbor, although the outer harbor channel is equipped with nearly a kilometer-long anti-submarine net, but because there are too many ships entering and leaving the port, in fact, it cannot be very effective in blocking the enemy submarine from diving, so we have installed a three-layer anti-submarine net in the inner harbor channel, and all of them will be closed after nightfall, and our permanent fleet and important ships are anchored in this safer inner harbor!"

At this time, the garrison commander of the port area, Feng . Auguste ground outside the window. A large ocean-going freighter is slowly sailing to the dock area not far away, and standing beside August is what he calls "Your Majesty", the fourth emperor of the German Empire, Gianlug, Wilhelm III.

"Every night, five vigilant detachments of destroyers and submarine hunters take turns patrolling outside the harbor, with a patrol radius of 25 to 30 nautical miles; Except in bad weather such as storms, at least three aircraft with radar equipment are guaranteed to patrol the port at all times, and their radius is usually 80 to 150 nautical miles, plus the effective search range of the radar. The maximum warning distance is 200 nautical miles outside the port; In addition, the 22 radar stations deployed near the port are working 24 hours a day! ”

When Chen Tian recited these key information on the defense of the port area in one go, August, who had originally planned to show it in front of the emperor in a small way, was so surprised that he almost couldn't close his mouth.

"I had the privilege of participating in the discussion when these warning regulations were first developed, and the numbers are constantly increasing with the use of new equipment, but maybe we will never be able to monitor the entire sea!" After only staying at the window for a moment, he habitually left the position where he was vulnerable to sniping without the attendant reminding him, of course, he didn't come here to listen to the so-called work report, in fact, he came to greet a guest, but the guest hadn't arrived yet. So he took it to the port garrison headquarters to take a look.

That's when it happened. A young officer in a Navy second lieutenant uniform knocked on the door and entered, reporting:

"General, the GA-1002 fleet is requesting to enter the port!"

August first glanced at Chentian and saw that the emperor did not say anything. He said in a cautious and serious tone as much as possible: "Strictly verify the identity of the other party, and pay close attention to the surface and underwater conditions when the other party enters the port!" ”

"Yes!" The officer quietly glanced at Chen Tian who was sitting on the sofa, his face turned red with excitement, but he didn't dare to say anything, and after saluting, he turned around and walked out of the room with some reluctance.

"How soon can they start unloading?" Chen Tian asked casually.

For this question, August was obviously not mentally prepared, he hurriedly picked up the notebook on his desk, "Your Majesty, this is a fleet of Class A ships, and they are 24 hours ahead of the scheduled arrival time!" Our procedure takes about 10 to 15 minutes. When I add the time of arrival, it is about ...... They will be ready to unload in about 40 minutes! Belch...... They will dock at Pier 2, which is very close to us, Your Majesty! ”

, 40 minutes ......" Chen Tian turned his head sideways, and the attendant officer who was standing two steps away took a step closer and leaned down, Chen Tian whispered a few words to him, and after whispering to him, the attendant left the room quickly, and poor Auguste didn't know where to put his eyes during the whole process, and he didn't look at it.

"General.

Please relax! Chentian put his hands on the hilt of his sword and motioned for August to sit down in front of him.

"I want to know that I am not alone in our port defenses, and it would not be surprising if the enemy knew this, knowing that nothing impossible happens in this world, and it seems that no matter how tight the defense is, the enemy may be able to break through in unexpected ways! Therefore, it is very necessary to maintain a cautious attitude that is not arrogant or impetuous in our daily work and life, we can neither neglect to take precautions, nor can we be conformist and self-righteous, we should believe in ourselves and our soldiers on the one hand, and on the other hand, we should constantly conduct self-examination and self-improvement! ”

August couldn't help nodding, but whether he really understood what he meant, Chen Tian didn't know, and he wasn't interested in delving into it, and in the next time he didn't communicate with August about the defense of the port, but gossiped in a more relaxed atmosphere, and a quarter of an hour later, just now, the fleet that had just arrived began to pass through the window, 4 large ocean-going freighters and 1 light cruiser and 4 destroyers escorting them, in terms of the size of the fleet, it was too ordinary, and the escort force was not so exaggerated, Even August, the commander of the garrison of the Qingdao port area, did not know what was on board those ships.

"A unique German national treasure in the world!" This is how Chen Tian himself describes the goods carried on this fleet.
