After staying in Sanfu Yuan for a while, plus there was no news worth noting, he also left early.

The next day, in the morning, Meng Chang muttered with Liu Qinghou, Meng Chang asked Liu Qinghou to wait on the side of the road in Hongkou, and if he found that the convoy was from the gendarmerie headquarters, he immediately drove away and sent him a telegram, this place had brought Liu Qinghou two days before. Now there are some things about Meng Chang, and Liu Qinghou also knows some things. However, Meng Chang didn't tell him about going to blow up the Izumo.

Meng Chang came out of the Mu Mansion at seven o'clock, the weather was not bad today, the white clouds were flowery, a little windy, with the fishy smell of sea water, Meng Chang first heard the car to step on the better place. There were a few big rocks in this place, just enough to block the car, Meng Chang took out the binoculars and looked at the place where the Izumo stopped by the sea.

The Izumo has now begun to warm up, puffs of black smoke are coming out of the big chimney, and there are several small gunboats patrolling around, Meng Chang saw that the defense was very tight. Now this position. About fifteen kilometers away from the Izumo, the submarine modified by Meng Chang can run up to 20 kilometers on the surface and only 9 kilometers per hour underwater. Meng Chang saw that there were no other changes, that is, the vigilance was higher than usual, and the number of patrol boats was not increased.

Just put down the binoculars, then move the submarine out of the car, start inflating, adjust the buoyancy, and then preferably check the submarine all at once. Buoyancy, the security of the bomb, the fixing of screws in various places, and whether the places that Meng Chang needs to adjust with his hands are reliable, and he will check it after a while.

Meng Chang sat down in the submarine, turned on the switch, and quickly slid on the water, because it was a motor, except for the sound of the propeller dialing the water, the sea was quiet, Meng Chang used a telescope to observe the situation in the surrounding waters, at this time the hard-working fishermen went to sea early to fish, there were not many boats on the sea, and there were about five kilometers away. This place was close to the dock, and all kinds of boats began to increase, Meng Chang didn't dare to be careless, and quickly got off the submarine and began to dive, ready to move in the sea.

At this time, the little devils also had submarines, and the losses caused by Germany to the British Empire with some cheap submarines during World War I were something that no country dared to despise submarines. The little devil is no exception, and the submarine is very hot for a while.

However, at that time, first, the strength, ductility and bending of the alloy were not up to standard; Second, the problem of batteries, the storage of batteries at that time was too small, the time of the submarine under water was too short, and the warships were equipped with mine nets to intercept torpedoes at that time, so it was difficult to achieve surprise. Third, it was the problem of torpedoes at that time, the distance of torpedo attack at that time was very short, and the submarine launched an attack in time, and the warship could lock on to the target quickly, so it was okay for the submarine to engage in merchant ships, and it was basically impossible to attack the warship. Due to the above three points, the submarine fever quickly cooled down, but various countries did not put down this project, after all, this is a low-cost naval weapon, as long as the designated position is reached, the time is well controlled, it can basically be said to be successful. Especially Germany,. The shortcomings in the navy and the shortage of funds made the German government and navy very fond of submarines, which was also confirmed in the later wars.

The little devil really deployed a submarine in China, but in Port Arthur, not in Shanghai, this made Meng Chang also relieved, if it was a submarine, he would not have planned to attack Izumo.

Meng Chang let go of the gas in the inner tube a little, dived to about ten meters, and then rowed towards the Izumo at full speed, under ten meters of water, people's eyes can only see ten meters, this is still Meng Chang's eyesight. However, Meng Chang put the searcher in his hand, so that he would not lose his direction.

It was a blue sea, a lot of small fish swam around, and occasionally there were one or two turtles, the temperature of the sea was very low, and Meng Chang felt the slightest coolness even when he was wearing a cotton jacket. After a while, they came to the five kilometers of the Izumo, the range of the gunboats patrolling the little devils here.

The eyes of the people on the ship are very poisonous, and the sailors are specially trained to distinguish between fish and submarines or torpedoes from movement and bubbles on the water. Meng Chang didn't dare to be careless, so he dived two meters and slowed down his speed. Observe the position of the gunboat with a searcher. Try to avoid the gunboats.

When it was three kilometers away, the patrol of the gunboats was intensive, there was no time to hide, Meng Chang dived three meters, and the water pressure at this time was not something that ordinary people could stand, and Meng Chang's internal strength automatically began to operate to resist water pressure and cold.

This is the sound of a propeller hitting the water, a gunboat patrolled to Meng Chang's head, the black pressure on it is like a dark cloud covering the top, giving people a very depressing feeling, plus the pressure on the water formed by the gunboat when it splits the water, Meng Chang's submarine began to spin, Meng Chang couldn't grasp the direction for a while, there was an undercurrent that took the submarine to float up, but Meng Chang was frightened, he didn't take into account the undercurrent at the time, the weight of this simple submarine is very light, coupled with the buoyancy of the seawater, it is a little unstable in the water, Immediately at this time, the brain teaser turned rapidly, what to do, this is the corner of the eye to see the bottom of the sea fifteen or sixteen meters away from himself, there is a large stone, Meng Chang took out the hardware hundred refining lock from the treasure bag, there are often more than 20 meters This is Meng Chang to climb high and low, there is a deerskin sleeve at one end, which can be put on the wrist, and there is a hardware buckle at the other end, which can hang a lot of things, can be hung to fly and grasp, can be used to climb the wall and cross the ridge, can be hung with hardware hundred refining hammers, this wheel is open, ten meters square, no one can stand, it is a common long-range weapon used by martial arts people, However, the others' are not as long as Meng Chang's.

Meng Chang put the deerskin sleeve on his wrist, hung the flying grab at the other end, and carried the internal force from the dantian to the right hand, Meng Chang shook hard, and the flying grab was buckled on the big stone, Meng Chang climbed lightly, and the five steel teeth of the flying grab were buckled into the big stone with a bang, Meng Chang climbed twice hard, and saw that the buckle was dead, and as soon as the right arm was forced, the submarine went down with the hardware lock.

Talking so much, in fact, it is just a matter of a few seconds, Meng Chang doesn't have to carry internal force now, and his body is not cold, it was too dangerous just now. If it wasn't for Meng Chang's quick eyes and quick hands at that time, he held the big stone, and now Meng Chang has surfaced, and he still has a bomb, not to mention anything else, the little devil on the warship saw a person suddenly appearing, and he won't listen to your explanation, it is directly a cannon and bullets, those heavy machine guns, rapid-fire guns, but they are not for watching and playing, they are all sharp weapons for killing, no matter how great Meng Chang's ability on the water, he has to explain. Do you think he can not be afraid?

The heart suddenly jumped into one, and he sucked hard against the oxygen cylinder (how strange it felt, sucking and sucking). The little devil on the gunboat didn't find any abnormalities on the water surface, and when the gunboat went away, Meng Chang took back the flying catch, and the speed dropped a little, to a speed of five kilometers, which is a little more than a kilometer away from the Izumo, Meng Chang thought about it, I dived directly to the maximum place, twenty meters underwater, which is the maximum water pressure that Meng Chang can withstand in full operation. Meng Chang can only hold on for half an hour, if nothing happens, he can reach the bottom of the Izumo in ten minutes, this is Meng Chang can rest assured, even if he floats a little more, he is not afraid, such a big warship is blocked, not underwater, no one can see it.

Meng Chang didn't dare to be careless at this time, under the water, grasping the direction of the submarine with his feet, staring at the screen of the searcher with his eyes, and holding a hundred refining flying in his right hand, he was lucky last time, but he didn't dare to be careless this time, well, it's strange to say, from avoiding the gunboat to the bottom of the Izumo, he didn't encounter the gunboat, Meng Chang put his heart down.

Meng Chang took a breath, opened the searcher at the bottom of the ship, and checked the internal situation of the Izumo, if you want to blow up the Izumo, it will not work at all with Meng Chang's self-made bomb, this is explosive, or relatively primitive, I don't want the explosives of later generations, miniaturization, and powerful scary. In a Meng Chang did not have time to specialize in this blow-up, there was no directional blasting, and there was no armor-piercing effect, just by virtue of the water pressure generated during the explosion, it was indeed possible to blow up the 175 mm special steel plate of the Izumo out of a large hole with a radius of one meter, and at the beginning this hole was really nothing for a 10,000-ton armored cruiser, and the skilled navy could quickly seal the watertight compartment at the ruptured position, and then balance the warship by releasing the water or moving the cargo at the bottom of the ship, but it would lose some speed, and there was nothing else.

So what to do, there are two ways, one is to find the side of the storage ammunition location, so that after the bomb explodes, the explosion of the ammunition depot will be caused, and the ammunition stored by the Izumo can directly break the keel, and the warship will sink to the bottom of the sea in an instant, so how many people can live, it depends on the will of God; Another way is to determine if there are torpedoes in the torpedo launchers, the Izumo has four 475mm torpedo launchers, and if there are fish, then the bow of the ship will be blown off, and the warship's ass will be cocked, and it will quickly sink to the bottom of the sea.

Now Meng Chang is determining the location of these two places, the Izumo is fully loaded and eight meters underwater, so that Meng Chang can resist water pressure and cold without using internal power at this water level. Meng Chang swept the inside of the cabin with a searcher, a good news and a bad news. The bad news is that there are no torpedoes inside the torpedo launcher, and this position can only be abandoned. The good news is that the location where the ammunition is placed is not too far from Meng Chang, and there is a lot of ammunition inside, Meng Chang saw it, and hurriedly got to work, so he put the submarine close to the side of the ammunition warehouse, and then in order to stabilize, there is a big stone fixed to the bottom of the sea, so that the bomb can be placed with confidence.
