Among the weeds that appeared next to the fence again, Bai Lidu and Zhou Ruolan also changed into student costumes for the first time.

Not long after he started running, an unknown song rang in Bai Lidu's ears:

[This time I'm obsessed with it, willfully intoxicated/I don't care, it's wrong or right/Even if it's deep, I'm desperate/Even if it's obsessed, I'm obsessed and don't regret it/Don't say I should give up, I should open my eyes......]

This time, it was Zhou Ruolan who took the initiative to play a song and shared it with herself, Bai Lidu also felt that the melody of this song was very good, and checked the title of the song, it turned out to be a song originally sung by Faye Wong "Obsessed Without Regrets".

"Ruolan, did you gain anything from your previous tracking of Sun Wei? Is there a key clue to the third key? ”

Zhou Ruolan replied: "I haven't found any key clues yet, by the way, is the tube of thallium salt solution that I transferred and handed over to you in the laboratory last time?" ”

"Huh?"

Bai Lidu didn't expect Zhou Ruolan to ask about this again, so he was a little speechless.

"What's wrong?"

Bai Lidu had no choice but to reply: "What, that tube has been used by me, is it still useful for you?" ”

"It's useless, it's just that the next day, I followed Sun Wei into the laboratory, and the teacher named Tong Ai found that a test tube was missing from the experimental table, so he asked Sun Wei if he had seen it."

"Oh? So how did Sun Wei answer? Bai Lidu asked curiously.

Sun Wei also replied that he didn't know, and he also guessed that it might be that other students who were doing experiments accidentally broke the test tube, and then Mr. Tong didn't ask anything more, by the way, where did you use that tube of toxic thallium salt solution? In the end, Zhou Ruolan was also very curious.

"Ahem...... It's a long story, but I went back to the Old Summer Palace again, but I was arrested by the Criminal Department, not only was I sentenced, but I was also put in prison......"

"Please! Say! Heavy! Dot! Zhou Ruolan pretended to be angry and said.

"Haha, okay, then I'll get to the point, and then I found a chance to successfully escape from the cell, and then I poured all the solution into Cixi's bowl, and she drank half of it."

When Zhou Ruolan heard this, she was also greatly surprised, and said loudly: "You mean, you used the poison that Sun Wei personally prepared in 1994 to poison Cixi in 1861!" ”

"That's right, that's how it should be!"

After listening to Zhou Ruolan's description, Bai Lidu instantly felt that he seemed to be quite awesome.

"What happened to Cixi? Poisoned? ”

Bai Lidu replied while running: "Hehe, if Cixi hadn't hung up, I guess I should still be locked up in prison now, but she was not poisoned, but An Dehai, who was possessed by Li Zilong, was stabbed to death with scissors." ”

"Ah......h

This plot has obviously already exceeded Zhou Ruolan's imagination, so it is naturally impossible to understand and digest it at once.

When the two of them ran to the front of the girls' building No. 6, they began to walk out of the dormitory door in twos and threes, and came out for a morning run or exercise, or went to the cafeteria for breakfast.

"Boss! Ruolan beauty, why are you both here too! ”

A familiar voice came, Bai Lidu looked for prestige, and saw a male player dressed in a student costume walking over, and through his voice and his appearance, he also recognized him, it was actually the pillar of the Guo family who had not been seen for a long time.

"Haha, it turned out to be Boss Guo."

The pillar of the Guo family immediately replied: "Boss, don't make fun of me, I have already joined our guild, and the Tianhe Gang before is basically about to fall apart, so don't call me Boss Guo anymore, I can't afford it." ”

"Huh? Is the Tianhe Gang falling apart? ”

"Yes, they all want to join our guild like me, but the places in our guild have always been scarce, and they can't be added at all......

Bai Lidu also nodded and said, "Well, I'll find a way to solve this matter, by the way, how long have you been guarding here?" Did you find anything? ”

"It's been about six or seven hours since the middle of the night, and it's been a ......."

When Zhou Ruolan on the side heard this, she immediately became energetic, and hurriedly asked, "What did you find?" Let's talk about it. ”

"Haha, Ruolan beauty, don't worry, I'll talk about ...... now"

"Don't talk nonsense, get to the point!" Bai Lidu also can't stand this guy anymore.

"Good! Last night, I stayed here, and I saw Sun Wei and Jin Ya and Wang Qi walking out of the dormitory building together, and I followed them until they walked into a Muslim restaurant, and when they were eating, I sat at the next table, and heard Sun Wei say that he was going home after eating, and the other two girls offered to send him to the west gate to take the car after dinner. ”

Zhou Ruolan also took it and said: "Well, yesterday should be October 28th, that is, Friday, Sun Wei should also go home on the weekend, so what about after eating?" ”

After eating, the three of them walked to the west gate of the school, but Sun Wei suddenly asked Jin Ya and Wang Qi to accompany her home, saying that they would stay at her house for one night and go back to school together the next day, that is, today.

"Ah, there is still such an operation? Then all three of them weren't at school last night? ”

Hearing this, Bai Lidu couldn't help but be a little surprised.

"That's not it, in the end, it was only Jin Ya who went with Sun Wei, Wang Qi didn't follow, I originally planned to continue to follow Sun Wei, but not long after I walked out of the West Gate, I was stopped by the enchantment, so I could only watch the two girls leave."

"Ah, and enchantments! Then it's only six o'clock in the morning at this time, and Sun Wei and Jin Ya shouldn't have come back yet, right? ”

"Yes, I haven't seen these two come back."

Zhou Ruolan also analyzed at this time: "I think there must be a reason why these two people left the school suddenly, so we might as well go to Ximen now and wait for these two people to come back, maybe we can find any clues." ”

Bai Lidu also felt that what Zhou Ruolan said was reasonable, after all, according to the information compiled by Xiaoyao before, the main suspects in this poisoning case, in addition to Sun Wei was ranked first, followed by Jin Ya, although Wang Qi was ranked third, but the probability of his direct participation in poisoning was obviously much lower than that of the previous two, and more suspicion of him was only knowing and covering up.

"Then let's go now."

"Good ......"

After Bai Lidu expressed his attitude, the three of them immediately rushed to the west gate of Jinghua University.

Coming to the west gate of the school again, Bai Lidu naturally saw the shopping mall where he first bought clothes with Ruolan, and the bookstore opposite it.

I walked out for a distance, and I really saw a looming light curtain, which was isolated from the outside world, and every now and then, there would be students in the school walking out of the school gate, or pedestrians or cyclists coming in from outside the school gate, and the three of them had to stay in a corner on the side, carefully observing the pedestrians entering the school.

Bai Lidu suddenly thought of a question:

"In addition to the West Gate, there should be other gates in Jinghua University, if these two people choose to walk back from other gates, then we will have to wait here in vain."

"Yes, what the boss said makes sense, I remember that the closest to Building 6 should be the East Gate, but why did they go through this West Gate when they left the school?"

Zhou Ruolan said calmly: "Don't worry, I happened to visit the campus of Jinghua University, and at that time in 94, considering the traffic factor, the West Gate is the most convenient to take by car, and if Sun Wei wants to rush back to the school from outside, it should also be the West Gate." ”

"Awesome! Served! ”

The pillars of the Guo family on the side let out exclamations one after another.

Of course, Bai Lidu also knows that Zhou Ruolan has put a lot of thought into the unsolved case of this century, so she can make such a confident judgment.
