Zhao Yulin heard the door being closed, and there was another sound of heavy objects falling to the ground, and he should have thrown the suitcase on the ground.

After that, all that's left is the snoring.

It should just be ordinary guests.

Zhao Shirui has been guarding the two alleys.

This is a secret stronghold of the nurse's boyfriend.

Zhao Shirui estimated that as long as Lin Zi'an's death was confirmed, the target would definitely flee here, either lurk or destroy all traces here and leave the city quickly.

His task was to arrest this person as soon as he appeared.

But after eight o'clock, the target still didn't appear.

There has been no news from the hospital, proving that everything is normal.

It was not his own people who did it, the Japanese just secretly changed the medicine, and it was reasonable to confirm Lin Zi'an's life and death first.

Once confirmed, the target in charge of carrying out the task will definitely find a way to get out of it at the first time.

But this bastard hasn't appeared, what the hell are you waiting for?

Could it be that the hospital was too calm and made the Japanese suspicious?

Zhao Shirui decided to take a look at the hospital again.

"You guys keep an eye on it, I'll go back to the hospital first!" Zhao Shirui threw the telescope to his subordinates.

It was business as usual in the hospital, and there was no sign that the murder had occurred only three hours earlier.

Ye Xingzhong was on duty as usual with two guards, but in fact, the ward was empty.

Lin Zi'an's body has been transferred, and doctors and nurses have been secretly taken back to the gendarmerie headquarters.

Zhao Shirui blocked the news as soon as possible, and even the people inside the hospital didn't know what had happened in this ward.

Zhao Shirui went straight up and asked a few words in a low voice.

"No one has come to investigate, and no doctors and nurses have ever asked, it's no different from usual...... Ye Xingzhong replied.

What the hell?

Why are the Japanese not in a hurry at all?

"Do you want to let go?" Ye Xingzhong asked.

"No need!" Zhao Shirui shook his head, "The Japanese will confirm it sooner or later, but I didn't expect them to really use such a stupid method!" ”

"What's the solution?" Ye Xingzhong asked subconsciously.

"Just keep an eye on Lin Zi'an's doctors and nurses!" Zhao Shirui replied, "Once Lin Zi'an is poisoned, the doctor and nurse are the first suspects, these two people do not appear, or as soon as their families are controlled, the Japanese will naturally know that the plan has succeeded......"

"It's not stupid, it's safe!" Ye Xingzhong asked.

"Stupid don't kill you!" Zhao Shirui sneered, "No wonder Fang Buwei said that you are not a spy...... Japanese people are not afraid of sudden accidents? For example, the nurse's hands were shaking, the medicine didn't go in, or the medicine was too little, and Lin Zi'an survived? ”

Ye Xingzhong opened his mouth, but he didn't know how to refute, so he could only stare at Zhao Shirui secretly.

It's not as complicated as Zhao Shirui said.

Fang Buwei had long expected what methods the Japanese would use to confirm the success of the operation.

It's okay to have people staring at the hospital lab.

Ye Xingzhong just said a rough idea, and Fang Buwei concluded that the toxin that caused Lin Zi'an's death was hydride.

With the exception of this one, no toxin can kill a person in a matter of minutes.

But in this day and age, even the average doctor doesn't know what the word cyanide means, let alone judge it by smell.

As soon as Lin Zi'an was poisoned, the cause of death must be investigated as soon as possible, and blood must be drawn for testing, and the entire Nanjing, and the Central Hospital have the corresponding equipment and personnel.

He asked Zhao Shirui to stare at the nurse's boyfriend, just to find out what other means the Japanese had prepared in addition to cyanide.

Fang Buwei had been pretending to be asleep, and at the same time heard the movement in the next room.

Zhao Yulin didn't go out, and the range of activities was very small, so Fang Buwei only heard him go to the bathroom once.

Fang is not improvising, the hospital should also have the results, and Zhao Yulin will be notified soon.

But it's not known what method they'll use to deliver the message.

Zhao Shirui has been following for so many days, except for the nurse's boyfriend, I haven't found out that Zhao Yulin has been in contact with anyone or passed on any information.

I haven't even made a phone call.

It won't be the nurse's boyfriend.

The Japanese will not be so careless and let the specific person who executes the operation work part-time as a liaison.

Zhao Yulin must have other contact methods, but Zhao Shirui didn't find it.

Fang Buwei thought that if he found out this, it would be possible to dig out Zhao Yulin's upline, that is, he had always suspected that after Zhao Jinshan's death, the Kwantung Army's secret service sent the successor to deal with Nanjing's intelligence affairs.

At nine o'clock, Fang Buwei heard a phone ringing, but it was not from Zhao Yulin's room.

The facilities in the annex building are simpler than those in the main building, and ordinary rooms like the one where Fang Buwei and Zhao Yulin live are not equipped with telephones.

On the entire second floor, only the two suites in the south are equipped with telephones, and the phones will only be answered if the guests ask for them.

Fang Buwei listened, and the phone rang from the suite on the east side.

The bell kept ringing, broke in the middle, and then rang again.

Taking advantage of this opportunity, Fang Buwei rolled out of bed, came to the wall lightly, and put his ear against the wall.

Zhao Yulin seemed to be standing up, flipping through something.

Fang Buwei heard the sound of "click" again.

This is a pistol check.

What is Zhao Yulin going to do?

Just then, the phone rang again.

What's the matter, which bastard, if you don't answer the first two times, it means that the person is not there, and you have to fight the third time?

Just thinking of this, Fang Buwei was stunned.

Could this be a code?

There is no need to send someone to deliver a letter, and there is no need to call in, just give Zhao Yulin a code and let him know that the mission has been successful.

The number of times the phone rings can tell whether Lin Zi'an is dead or alive, or even half dead?

Fang Buwei sneered, quietly waiting for Zhao Yulin's next reaction.

If his guess is correct, Zhao Yulin will leave the hotel after receiving the code.

After the bell stopped, Fang Buwei heard Zhao Yulin lift the suitcase and open the door.

Sure enough, the Japanese used unanswered calls to pass on codes.

Not surprisingly, the room that rang was not occupied, but someone opened the room, asked the hotel to turn on the phone and left.

The Japanese also used the same system of the underground party, and it seems that they have suffered a lot of losses, and they know that they have learned a lesson.

When Zhao Yulin's footsteps walked farther and farther, and when he stepped on the stairs, Fang Buwei walked out of the room in a hurry.

When he went down to the first floor, Zhao Yulin was standing at the front desk, as if he was checking out.

Fang Buwei thought about it and dispelled the idea of installing a tracker or bugging device for Zhao Yulin.

If he is not mistaken, Zhao Yulin will leave the city after leaving the house, if during this period, he still can't find out who Zhao Yulin will contact and who the contact object is, Fang Buwei will do it.

I've already let him go once, and I can't let him go a second time.
