Zuo Zhong immediately retreated to the door and carefully observed the main room. The room in front of him was about ten square meters, with a small wing on the east and west sides, and the floor was paved with large ceramic tiles.

Since it is a booby trap, it is nothing more than pulling, tripping, pressing and other methods. Just check them one by one. The most likely place to place the trap is on the ground. Other locations are too conspicuous.

He recalled the types of booby traps, then lay down directly on the ground, tilted his head and looked into the house close to the ground. At the same time, he turned on the flashlight for auxiliary lighting, trying to see if there was any trip wire.

As a result, the ground above was very clean, and there was no object that could be used as a stumbling block. Unless the Japanese invented some kind of completely transparent substance, it was impossible for such a thing to exist.

In this era, only transparent plastic can achieve similar effects①, but even transparent plastic is only nominally transparent and still has an obvious color under the light.

He frowned slowly. This kind of open space was very suitable for setting up trip traps, while pull traps were basically used on moving objects, such as doors and windows. The ground was not suitable for such booby traps.

Is that a hair pressure trap?

Zuo Zhong continued to lower his head and began to compare the heights of the tiles. Pressing requires a certain amount of space. If the spy really buried something under a certain floor tile, no matter how perfect the arrangement was, there would be traces left.

At this time, the sun was rising high, and beams of golden sunlight were shining into the house through the window lattice. Under the light, the dust flying in the sky was clearly visible, which greatly increased the difficulty of observation.

After a long time, he got up with an ugly face. The ground was very flat. At least there was no problem visible to the naked eye. He couldn't crawl on the ground to check inch by inch. There was too little time.

He raised his hand and looked at his watch. It was already 6:45, and he hadn't even entered yet. If he delayed further, it would be the peak flow of people. He couldn't wait until there were fewer pedestrians nearby before leaving.

Because once the operation against the official residence and Meng Ting starts, various calls will come into the Intelligence Department. If he continues not to answer the phone, it will definitely arouse the suspicion of Dai Chunfeng and his subordinates.

A solution must be found as soon as possible.

His mind was running rapidly, and his eyes accidentally saw the well in the courtyard, and a flash of inspiration flashed by. If the height difference on the ground cannot be seen clearly with the naked eye, then use reference objects.

Zuo Zhong seemed to have thought of something and gradually smiled. Then he stood up and walked to the well to fill up a bucket of water. He took out his pen, unscrewed the pen body and squeezed ink into the bucket.

Soon, the bucket of water turned light blue. He found a ladle from the kitchen and poured the water in the bucket into the house, repeating this process until the ground was completely wet with blue liquid.

This old-fashioned glazed ceramic tile has very poor hydrophilicity. After being splashed with so much water, water quickly began to accumulate on the ground. Due to gravity, the water would flow from high places to low places. This was the method he came up with.

Just like the closed water test in later generations, using water with colorant to determine the level of the terrain, he didn't believe that Tianfu could make the trap perfectly, and he couldn't be a spy with such skills.

Besides, traps need to be checked from time to time and dangerous goods replaced. Even if the gap is relatively small at the beginning, after such a long period of use, wear and tear will inevitably occur and the gap will only get bigger and bigger.

Zuo Zhong half-crouched on the ground, staring at the slowly fading water traces with wide eyes, and finally found two tiles where the water quickly gathered but disappeared quickly. What a double insurance.

One of the floor tiles is not far from the door. It is specially prepared for people entering the door. Without knowing the layout of the room, as long as you take two steps, it will turn into flesh and blood fireworks with a bang.

The other one is at the door of the bedroom, which is a must-have for the search. Fortunately, they arrested the person at the Central Hospital, otherwise they would have paid a heavy price. These two traps are too insidious.

If Tianfu was not dead, he really wanted to ask the other party if he wanted such a big battle, wasn't this guy afraid of stepping on a trap, or would the other party dismantle the trap temporarily every time he came here.

Also, a safe house is more concealed than a personal residence, and the slower collection of items is not a big problem. As long as you can ensure the safety of yourself and your intelligence, it is worth spending a little more time.

"Let me see what's in there."

Zuo Zhong moved his hands, carefully walked into the house, and stopped next to the first tile. No matter from any angle, it was just an ordinary floor tile, with nothing special about it.

He lay on the ground again and carefully groped the edges of the floor tiles with his fingers, looking for abnormalities. He soon discovered that the corners of the floor tiles were somewhat loose, and it seemed that he could lift them with a little force.

But you can't do this. It's best not to act rashly without seeing the situation clearly and confirming the specific trap type. The methods of handling various booby traps are very different, and tampering with them is courting death.

Based on his understanding of Tianfu, this Wang Ba Dan is likely to choose a compound trap, that is, using pull, trip, and pressure together. You must be careful when handling this floor tile.

Zuo Zhong gradually lifted the corner of the floor tile a few centimeters, then slowly inserted a dagger into the gap as a support. Finally, he turned on the flashlight and looked inside with his eyes close to the small gap.

This sight made him break out in cold sweat. There was a suitcase in the trap. There was a land mine on the suitcase, and the safety pin had been pulled out. The upper pressure rod was very close to the tiles.

As soon as someone steps on the floor tiles, the firing pin will activate the radium tube to detonate dangerous goods. This is a standard army combat method. It is rare for intelligence personnel to use such dangerous weapons in the city.

At the same time, he also understood why Tianfu chose such large tiles to lay the floor, because in addition to installing booby traps, the trap was probably also a safe for the opponent to store items.

This is reasonable. There are many secrets in the safe house that cannot be discovered, such as radios and intelligence. Placing these things in traps will not only hide them, but also ensure that they do not fall into the hands of the enemy.

Once the booby trap explodes, it can not only destroy the enemies entering the safe house, but also destroy the items in the trap. It is another sense of dying together without leaving any evidence.

Moreover, this suitcase should be custom-made. Not only is it just the right size to fit into the trap, suitcase, mines, and tiles, but the combined height of the three is almost the same as the height of the trap.

In addition, there is an iron hook on the back of the tile, with a wire rope hooked on it extending into the suitcase. Needless to say, it is another booby trap, and this room is a dangerous goods warehouse.

Zuo Zhong wiped the sweat from his head and put two fingers into the gap, trying to release the hair booby trap. The gap was too thin and the pliers couldn't fit in, so he could only use his fingers to unbuckle the buckle.

He didn't dare to blink and stared at the trap. His fingers dexterously bypassed the mine and clamped the wire rope decisively. This step was not difficult, but the really difficult next step was to remove the rope.

At this time, the wire rope was already very tight. If he was not careful, the booby trap would be detonated. He was sure that the fuse of the booby trap must be very short. Once triggered, he would have no chance to escape.

One second....

Three seconds....

Ten seconds....

Zuo Zhong felt that the time had come, so he held the wire rope and left the hook without hesitation, then closed his eyes. After waiting for a few seconds, nothing happened, and the most dangerous booby trap was lifted.

The remaining mines are easy to deal with. Just remove the floor tiles above. After all, there is no direct contact between the two and the mines are in a deactivated state, otherwise it would be really troublesome.

"call."

He gently pushed the floor tiles aside, and then let out a long breath. This kind of thing should be done by Gui Youguang, and it would be difficult for Tianfu. Every time he collects something, he has to risk his life.

After resting for a minute, he quickly disarmed the trap under another floor tile. There were also two booby traps and a suitcase. The only difference was that this suitcase looked slightly larger.

What will be in the box?

After Zuo Zhong made sure that there were no problems underneath the boxes, he took them out, and then checked the zippers again, fearing that Tianfu would do something else to the boxes again. The tactics of these Japanese spies were too vicious.

Fortunately, Tianfu may have thought that the previous two traps were enough. Apart from a radio and a bunch of weapons, the two boxes only contained the two booby traps and a lot of banknotes from various countries.

Zuo Zhong roughly nodded. There were about 70,000 to 80,000 US dollars, pounds and other foreign currencies. Counting Dayang, it was estimated to be more than 100,000. With the money he brought, the underground party should not be short of funds in the near future.

The radio station is a miniature radio station produced by the Japanese. It comes with a lot of accessories, including three batteries. It is probably prepared by Tianfu for long-term lurking, but now it is all owned by the underground party.

You can't buy these things with money, and the government's management of electrical materials is becoming more and more strict. Even the telecommunications section needs Dai Chunfeng's personal order to buy accessories. The telecommunications section chief's small business stopped last year.

Mr. Tianfu, you are such a good person.

Zuo Zhong smiled and put on his gloves and took an MP18 in his hand to look at it. It was brand new from Germany. There were 5 pieces in the box. The matching bullets had at least a thousand rounds, which was enough for use.

Although this thing is not as good as the Thomson, it definitely has heavy firepower for the underground party. If it shoots at Xu Enzeng's vehicle, it will kill him in one shot. It is an absolute killer.

Putting down the MP18, he looked at the bottom of the box again. Good guy, there are also about ten Browning M1910s. The Japanese really love this gun so much that they have prepared so many spares.

Zuo Zhong pulled the sleeve with a satisfied smile on his face. Nandou was just an intelligence team. To have such a harvest was beyond his expectations. People should know how to be content.

After counting the money and supplies, he stood up and walked around the room. He found no intelligence documents or valuable clues, no more booby traps, and no traces of his life.

Listening to the gradually noisy Suzaku Street outside, he felt it was time to leave, so he casually put the cash and documents into the box, then attached the mine's safety tether and put it aside.

This time it was just a meeting gift. When the right opportunity came, he was going to get some real heavy weapons for the underground party. In the future, the situation between us and the enemy will become more and more complicated. Only by having a gun in hand can you not panic.
