Wu Tongguang had just thrown most of the roasted sweet potatoes he had eaten into the garbage heap. At this time, there was an extra bag of melon seeds and a bag of popcorn in his hand.

Wu Tongguang did not lose heart, and continued to walk to the next area that he had not yet visited, and finally his efforts paid off, and he learned from a vendor selling rock sugar gourds that there was indeed a military truck that had stopped nearby just this morning, and several people in black Mao suits jumped out of the canvas compartment of the truck.

It's just a pity that the stall owner who sells rock sugar gourds was busy looking for money for customers, and in a gap where he bowed his head, these people disappeared without a trace in his field of vision, and the truck then started and left.

Wu Tongguang asked a few small traders around, and even knocked on the doors of several houses, and the answer he got was either "I didn't pay attention" or "I didn't see it".

Wu Tongguang stood where the truck had stopped, looking around. The place where he stood on the soles of his feet had intersections all around, that is, it was possible for He Hongwei and his party to go in any direction. Then it is still very difficult for Wu Tongguang to further reduce the area.

Wu Tongguang stood in place and thought for a moment. I saw that Wu Tongguang's brows were furrowing deeper and deeper, as if he had encountered some thorny problem. In the end, until Wu Tongguang left, his face was still full of sadness, and he still didn't seem to think of any good solution.

One day later, in the afternoon, Wu Tongguang was drinking tea alone in a small teahouse, he came very early, and the pot of tea he ordered had already made the guy refill the water twice, and the taste of tea was much lighter.

Wu Tongguang sat by the window, drinking tea while staring at the shop opposite. The shop opposite the teahouse is actually a shop selling sauce elbows, and there is nothing special about it compared to the other shops on the whole street.

But Wu Tongguang seems to have a soft spot for this shop that sells sauce elbows, and he has been staring at this shop since last night, and Wu Tongguang didn't go home to sleep until the shop closed. No, today Wu Tongguang specially asked Liu Congwen for a day off, and came to the teahouse opposite early in the morning to start a new round of squatting before the shop opened.

Wu Tongguang picked up the teacup again and took a sip of tea, Wu Tongguang frowned slightly, the tea at this time was actually too light to drink any tea. Just as Wu Tongguang wanted to ask the guy to change another pot of tea, suddenly a familiar face came into his sight.

I saw that this person was wearing a black tunic, and it was estimated that he was in his early thirties. This person first looked around vigilantly for a moment in front of the shop where he bought sauce elbows, and when he saw the teahouse across the street, Wu Tongguang recognized him, he was a member of the action team of He Hongwei of the Nanjing Station Operations Department, and everyone called him Ah Fei. Yesterday morning, among the six people who boarded the military truck at Nanjing Station, Ah Fei was one.

Wu Tongguang's whole person seemed to freeze on the chair, and after a while, Wu Tongguang was overjoyed and smiled. Wu Tongguang has been sitting in the teahouse since early in the morning, pouring a stomach full of tea, and he is the one who is waiting for him.

Because the teahouse where Wu Tongguang was located was backlit in the afternoon, Ah Fei couldn't see who was sitting in the teahouse opposite. Ah Fei saw that there was nothing unusual around, so he walked into the shop quickly. After a while, Ah Fei walked out of the shop carrying a large paper bag.

Wu Tongguang hurriedly took out a banknote and slapped it on the table, shouting at the young man, "Check out, don't look for it!" With that, he walked out of the teahouse quickly.

When Wu Tongguang just walked out of the teahouse, a young man's voice sounded behind him, "Sir, you have already given money in the morning!" ”

Wu Tong didn't reply with a bald head, and replied casually, "When I buy you sauce elbows!" As soon as the words fell, Wu Tongguang quickly left the teahouse and followed in the direction where Ah Fei left.

Wu Tongguang followed Ah Fei all the way, and it could be seen that Ah Fei was very cautious, and he would stop and look vigilantly behind him after taking a few steps. Wu Tongguang has always kept a relatively safe distance in order not to be discovered by the other party, and Wu Tongguang and Ah Fei are not very familiar with each other, so Wu Tongguang has dressed up a little bit this time, so it should not be so easy to be discovered.

It wasn't until he turned two streets and drilled out of an alley that Ah Fei finally stopped in front of a two-story building. In front of the door of the small building is an open area, except for a few bare trees, there are no obstacles. Therefore, Wu Tongguang could only hide in a far away wall and continue to observe Ah Fei's movements.

I saw that Ah Fei was still looking around vigilantly as he was in front of the shop selling sauce elbows. Seeing that there was nothing unusual around, he only knocked a few times, and then his lips squirmed a few times.

Because Wu Tongguang was too far away, he couldn't hear what Ah Fei was saying at all, but Wu Tongguang estimated that he was just reporting his name and letting the people inside know that it was his own person.

It didn't take long for the door to be opened. Ah Fei rushed in one step, and then the door was closed again. Even though the distance was relatively far, Wu Tongguang still heard the sound of "bang" closing the door very clearly. From this sound, Wu Tongguang could tell that this should be a very heavy iron door.

The door to this small two-story building is made of iron, which can effectively prevent forced entry. There is a window directly above the door of the small building on the second floor, and there is no courtyard in this room. It can prevent someone from sneaking over the wall. The front door of the small building is in an open area, and there is almost no place for people to hide. Judging from the above points, it is fully in line with the standards for the selection of safe houses by military commanders.

Now that the location of He Hongwei and his party has been determined, let's talk about how Wu Tongguang tracked Ah Fei now. Just yesterday afternoon, when Wu Tongguang was at a loss for the whereabouts of He Hongwei and his party, he thought of a way that was either a way, or to wait for the rabbit.

This method of waiting for the rabbit is based on the usual preferences of He Hongwei and his party and the rattlesnake, such as what food they usually prefer, and then Wu Tongguang squatted outside the shop where he could buy this kind of food, and waited until they came to buy it.

However, there is a lot of luck in this method, according to Shang Qingyuan's information, the rattlesnake will only stay in Nanjing for three days, only three days, He Hongwei and his party and the rattlesnake can temporarily endure their usual preferences in order to avoid extraneous branches. If so, then this approach is completely futile.

Wu Tongguang was standing on the street at that time, at a loss, and he couldn't think of any other better way for a long time. You can only try your luck in this way, and then you can pray that the heavens will do as you wish.

After Wu Tongguang decided, he contacted Shang Qingyuan and asked Shang Qingyuan what special hobbies the rattlesnake usually had. Wu Tongguang's question was quickly answered, and the rattlesnake's biggest hobby is sauce elbows.

After Wu Tongguang learned about it, he first visited all the shops in this area, but fortunately, most of the people living in this area are middle-class, ordinary people, and they rarely buy high-priced foods like sauce elbows, so there is only one store selling sauce elbows in this area.

The next thing Wu Tongguang had to do was to squat patiently, and in the whole process of squatting, Wu Tongguang prayed countless times, "Rattlesnake!" Rattlesnake! If you want to eat anything, don't put it back, be sure to ask them to buy it for you! ”

Sure enough, the hard work paid off, so Wu Tongguang waited for Ah Fei, and then tracked all the way to determine the location of the safe house.
