Li Wutong straightened his face and said: "You, you are just pretending to be smart, even if it is a trap, it does not necessarily refer to Zhao Cheng." ”

Wu Tongguang continued: "You are testing me, in addition to the meaning of the circle, it also reminds me of the circle in mathematics, we all know, Zhao Cheng is a famous expert in digital cryptography, and the three numbers of pi 3.14 and 3.14 are not exactly the fourth batch of students who studied in Moscow in 31 years?" ”

Li Wutong smiled happily and said, "Fortunately, in my few cultural knowledge, I still know that there is such a thing as pi." ”

Wu Tongguang said with a smile: "I guess only I can understand your clumsy and low-level warning method." Unconsciously, the two have established an extraordinary tacit understanding.

Wu Tongguang deliberately wrenched his face: "The light twists out the circle, of course, it may seem like a coincidence, but I have checked the scene before, taking the body burning as the path, the grass and trees within the range of five zhang are burned out, to burn an old jeep, but also to cause such a fire, the car fuel tank at least more than half of the gasoline, the wreckage of the car's fuel gauge pointer pointed to the middle of the fuel gauge and did not return to zero, what does this mean?" ”

Li Wutong was even more incomprehensible, and hurriedly asked, "What does this mean?" ”

Wu Tongguang said carefully: "It takes at least half a tank of fuel to cause such a fire, and the fuel gauge pointer at the scene is still pointing to half of the position, is it possible that your vehicles did not use fuel all the way?" Obviously this is not possible. ”

"Then the fire must have started the remaining half of the tank of fuel, which leaked out and caused the fire. In other words, the amount of fuel needed to start a fire is never lower than the reading of the fuel gauge hands. ”

Li Wutong said: "What you said is not wrong, continue to speak." ”

Wu Tongguang said leisurely: "Since it is the remaining half of the tank of fuel that caused the fire, there will be a suspicious place: if the vehicle is hit and causes an oil leak, the fire will slowly burn, then with the slow oil leakage process, the vehicle's fuel gauge pointer will slowly decrease and gradually return to zero." But ......."

Li Wutong said: "But the pointer of the fuel gauge still points to half the position. ”

Wu Tongguang said: "Yes, this is the suspicion, this suspicion shows the opposite. ”

Li Wutong said: "What's the situation? ”

"That is, when the fuel tank is completely leaking, the vehicle's fuel gauge has been completely destroyed, that is to say, within a few tens of seconds before the oil leakage, the vehicle's fuel tank assembly has been hit by bullets, which instantly triggered an explosion, and at the same time the fuel gauge was destroyed, and it was no longer possible to reduce the reading, let alone return to zero."

"Therefore, I suspect that this was not an accidental fire caused by rolling rocks, but a fierce shootout that went back and forth."

Li Wutong clapped his hands and said with a smile: "What are you coming and going, this shot is naturally this girl's masterpiece, yes, Zhao Cheng said before acting: 'Hell, how can there be no oil?' That's when I was wary of him. ”

"Wu Tongguang, since you know how dangerous it is to come to this liaison house, why do you need to come?"

Wu Tongguang looked at Li Wutong for a long time and said, "Then since you know better than me how dangerous this place is, why do you need to come?" ”

"Hey, this Wu Tongguang is so smart that he can guess anything, but he can't guess this simplest thing." Li Wutong thought sullenly in his heart.

In fact, it didn't have to kill Zhao Cheng. Wu Tongguang began to regret it a little.

If he waited another quarter of an hour, he should be able to realize that Li Wutong was not dead, and was even outside the door. In this way, the two of them have more ways to deal with this defection.

"But anyone, in that case, can only strike first." Li Wutong said.

It's just that she didn't know Wu Tongguang's heart at that time. Because no matter from which point of view, he didn't deduce that Li Wutong still had the possibility of surviving at that time, and no one could estimate the grief in his heart, so when Zhao Cheng pulled out his gun, he shot and killed all the enemies in anger.

Of course, this anger also stems from the disgust for traitors, and it is also to seek justice for Shang Qingyuan, if it were not for Zhao Cheng to explain that Shang Ji Pharmacy is the contact point of the CCP, Shang Qingyuan would not have sacrificed.

Wu Tongguang's temperament is introverted and deep, like a calm and wide lake, but the calmer the water surface, the more it contains the emotions of a torrent.

Zhao Cheng should stay alive. The high-level student of this digital cipher has also been engaged in secret work for a long time, and the extent to which his defection has caused leaks really needs to be further estimated.

"There's no time to regret it, you have to translate this instruction quickly." Li Wutong said.

Yes, this information almost killed Li Wutong and Wu Tongguang, and now we must quickly figure out the situation.

Wu Tongguang quickly translated the content of the intelligence.

"In the south, to avoid lightning and lightning, Lei Yin took the second train to Beijing in six days to prevent ghosts along the way."

Lei Yin is the code name of the organization's important sleeper in military operations.

"Operation Thunder Sound" means the most urgent operation at the highest level, and the information transmitted by Thunder Sound must be 100,000 urgent.

If there is thunder and lightning in the sky, it means that important military information has been obtained. The defense against bandits along the way was to instruct Wu Tongguang to take advantage of his advantage in penetrating into the enemy's special organization to secretly protect him. The south, in fact, means the opposite, which should refer to Beiping.

In order to redeem the defeat, Chiang Kai-shek transferred Fu Zuoyi from Zhangjiakou to Beiping and appointed him as the commander-in-chief of the "Suppression Chief" in North China, and controlled the armies of Shanxi, Hebei, Rehe, Chahar, Suiyuan, Beiping, and Tianjin. The Kuomintang and the Communist Party had already entered the stage of decisive battle on the battlefield in the north, and the struggle on the hidden front had also entered a white-hot one, and the organization launched the "Operation Lei Yin" at this time, indicating that important military information had been obtained, and life and death depended on it.

"What now? If you leave the Nanjing Station of the Secret Bureau, most of the enemies will be suspicious, and you may be in danger when you go back to the city. Li Wutong asked.

Wu Tongguang thought for a moment and said: "I'm afraid we don't have time to hesitate, even if we go up the knife mountain and go down to the sea of fire, we must protect Lei Yin and send the information to Nanjing safely." ”

"Do you know what you're doing? If your identity is exposed, you are killing yourself if you go back now! ”

"No, I have to go back."

"Lei Yin is earlier than me in the latent qualifications, presumably his ability is even more extraordinary, and now he wants to escort the intelligence to Nanjing, and the organization requires me to do my best to protect it, which must be a great difficulty for him. Besides, although I don't know Lei Yin, Lei Yin must have received information about me, but he knows me, and in case of danger, he will take the initiative to ask me for help, and I can't help but go back. ”
