Putting down the business matter, Zhang Yang first called Wang Yuyan and reported her safety.

Wang Yuyan asked him what he was doing last night, Zhang Yang made up a few lies and fooled the past, as for Wang Yuyan whether he believed it or not, he didn't care.

When he called Situ Yunsheng, he didn't mention last night's incident, but just told her that he had bought another phone and could call if he had something. And Situ Yunshang was in a meeting in the company, and he left the phone after two "uh-huh" sounds, which made Zhang Yang slightly disappointed.

Calling Fang Lili was the longest time to chat, Fang Lili was walking alone on the beach at this time, she first complained to Zhang Yang for a while, and then twittered Zhang Yang about many things about the small fishing village, Zhang Yang listened carefully with a smile, and occasionally made a few funny words, which made Fang Lili talk more energetic.

The floating power of the new mobile phone was soon gone, and thanks to the power bank full of electricity in Zhang Yang's storage space, he took out one when no one was paying attention, which made this long chat continue, until Fang Lili's mobile phone ran out of power, and the muscles on Zhang Yang's face stiffened at this time.

The place where Zhang Yang sat was not far from the fire shop where he had last bought oxygen equipment, and he took the opportunity to buy a second set and fill the bottles with oxygen (medical oxygen is not pure oxygen, it is a mixture of gases).

When he was about to go out, Zhang Yang asked if there was a tool that could monitor oxygen concentration, and he really asked, and the boss recommended to him something called "Oxygen Concentration Meter in the Air", which is shaped like a walkie-talkie and has a protruding antenna on its head.

Zhang Yang didn't say a word and bought it, he carried dozens of catties of things back to the place where he was chatting with Fang Lili on the phone, and took advantage of the fact that others were not paying attention, and put all the things he bought into the storage space.

Zhang Yang first glanced at the data on the "measuring instrument", and the oxygen concentration in the space was only a quarter of that of normal air. No wonder those three guys are like roosters pierced in the neck. He opened an oxygen cylinder and filled the space with oxygen, and the numbers on the "meter" slowly changed.

Zhang Yang breathed a sigh of relief, everything was in line with his expectations.

Next, Zhang Yang's attention was attracted by the metal of the rectangular shape. This dusty and dim metal-like body in the dirt was removed by the laws of space when it was collected into the space, and now its surface is as smooth as a mirror, very beautiful.

How does Zhang Yang look at how it looks like a silver ingot that has been finely polished, Zhang Yang turned it over with his mind, and did not find a place with a buckle, this will definitely not be a metal box, Zhang Yang thought for sure.

But what kind of metal is this? Metallic silver doesn't have such a density, even platinum and platinum can easily penetrate through his perspective energy, so it's not.

Zhang Yang compared the metal elements in the periodic table one by one, and thanks to the fact that he had just finished the university entrance examination, the properties of all the metals on the periodic table could still be recorded, and he came to the conclusion that none of the elements had properties similar to this metal.

Maybe it's an alloy? But it's so high-tech that it's not something he can study.

Zhang Yang couldn't figure it out, so he stopped wasting brain cells, and asked her when little Lori grew up in the future.

……

At 9 a.m. on June 26, the coordination meeting for the "621" prison escape case and the "625" shooting case was held in the conference room of the Municipal Public Security Bureau.

Ouyang Ren, director of the Municipal Public Security Bureau, presided over the meeting, Yu Jiyang, deputy director in charge of criminal investigation, Li Chao, director of the Technical Department of the Municipal Public Security Bureau, Han Xianjun, captain of the Municipal Criminal Police Brigade, Zeng Qingdong, the new captain of the Municipal Anti-Drug Brigade, Wang Feng, director of the Dongda District Public Security Bureau, Qiu Zhaoxia, captain of the Dongda District Criminal Police Team, and the professional backbone of the city and district criminal police teams attended the meeting.

At the meeting, the "621" and "625" cases were merged into the "621" case, and a "621" case task force was established, with Director Ouyang Ren personally serving as the team leader, Yu Jiyang as the deputy team leader, and the leaders and business backbones of various departments participating in the meeting became members of the task force.

Han Xianjun and Zeng Qingdong respectively briefed the special case group on the progress of the investigation of the two cases, and after the report, Han Xianjun specifically mentioned several suspicious points about Zhang Yang in order to attract the attention of the special case group.

Director Ouyang affirmed the investigation of the case, and assigned the next task, instructing Han Xianjun to include Zhang Yang in the scope of key investigations, and if necessary, he could obtain the support of the State Security Bureau. He stressed that the case must be cracked within one month, otherwise all members of the task force, including him, will ask for punishment.

The pressure on the members of the task force suddenly increased, and after the meeting, the intense investigation work began. Unbeknownst to Zhang Yang, his strange behavior in the two incidents had attracted the attention of the public authorities.

……

Zhang Yang observed the metal block for a while, and he didn't understand the essentials at all. He looked at the data on the "meter" again, and the volume percentage at this time was 11.4%, which was about half of the volume percentage of oxygen in the air at normal air pressure.

That is, one bottle of oxygen adds about 5% to the volume ratio of the space, and two more bottles can achieve normal oxygen concentration. Zhang Yang simply opened two more bottles of oxygen until the oxygen reached the same concentration as the oxygen in the air.

Zhang Yang carried three empty oxygen cylinders to the firefighting equipment store again, and filled the three bottles with oxygen in the surprised eyes of the shopkeeper.

Turning around and leaving the store, Zhang Yang had a feeling that I had in the future, and this feeling was very refreshing.

went to KFC to eat a set meal, and Zhang Yang went straight to Jinbei Automobile Company.

In the second year of high school, Zhang Yang and Zheng Feihong took advantage of the fact that a driving school offered preferential treatment to students on vacation, and took the driver's license together, so there should be no problem in opening this kind of blue brand small box of goods.

All the formalities of the car are very complete, and it is fully insured, Zhang Yang drove the car back to the fruit store with a bump, and his parents saw that he actually bought a car and came back, so angry that Zhang Yang scolded him, Zhang Yang could only listen to it resignedly, who let him do this thing really not very well, and did not say hello to his parents in advance.

There was nowhere to put the car outside the fruit store, so his mother asked him to drive the car home first, and then go back in the evening to study what to do? There were a lot of people in the fruit store, and it was not the time to explain this kind of thing, so Zhang Yang could only drive the car home depressed.

After taking a shower in the house, Zhang Yang went to the balcony and carried the Akita cub to the living room.

This puppy is yellow and white, with a transitional color between yellow and white, two triangular ears leaning forward slightly, a black kiss and nose, it looks very beautiful and docile, and when Zhang Yang picks it up, it stretches out its pink tongue and licks his palm.

Zhang Yang gave it a name called Xiao Huang, which was based on the color of its fur.

When it was playing, Zhang Yang put it into the storage space, and the puppy in the space closed his eyes and lay in the virtual grid, as if he was asleep. Zhang Yang looked at it for a while, and he was interested, and he saw that the data on the "measuring instrument" had not changed, so he stopped caring about it and took the storage space back.

I didn't sleep long last night, Zhang Yang was sleepy, and he fell asleep after lying on the bed for a while.
