Song Zihang took the amber and looked at the mosquito in the amber, this mosquito is surprisingly big, it can be about six centimeters in size, I don't know how many times bigger than the current mosquito, but this mosquito should still belong to the child-level mosquito in the Jurassic period, and the size of the adult mosquito in the real Jurassic period should be about eight or nine centimeters.

During the Jurassic period, the oxygen content of the air was about 25 percent, and now the oxygen content of the air is only 21 percent, so due to the high oxygen content in the Jurassic period, it can still support some insects to become larger, such as mosquitoes, dragonflies and so on.

However, at this time, the size of the insects was very large, but it could not be compared with the insects of the Carboniferous period, during the Carboniferous period, the oxygen content in the air was as high as 35%, such a high oxygen content, resulting in the strangely large size of the insects in that period.

For example, a dragonfly can grow to the size of a small unmanned reconnaissance aircraft, a giant centipede can be the size of a car, and various giant creatures are the overlords of the earth in that era.

Later, as the oxygen content of the earth became lower and lower, and finally large insects withdrew from the stage of history, and various reptiles began to appear, and a group of overlord-level creatures emerged among the reptiles, that is, the dinosaur family that ruled the earth for hundreds of millions of years.

Song Zihang took the amber and looked at it from beginning to end, then put it in his pocket, turned around and was about to leave, but just as Song Zihang turned around and was about to leave, suddenly a figure caught Song Zihang's attention.

It was a graceful figure, bumpy and convex, lurking in the shadows at this time, like a kitten ready to attack at any time, Song Zihang glanced at the person, a little curious, and looked at it for a while.

With Song Zihang's observation, Song Zihang couldn't help laughing, Song Zihang knew the intention of this person, this guy was obviously a thief, dressed in night clothes, covering his face, and hanging various tools on his waist, at first glance, he was a thief who specialized in stealing things.

The thief went around, then took out an electric car from his pocket, let it out, and the next moment took out a mobile phone to check the information screen on it.

Song Zihang was a little curious, this was all stolen, why didn't he forget to play with his mobile phone, this mobile phone is so good, it's so fun that he even forgot about business?

Song Zihang thought about glancing at the thief's mobile phone screen with his eyes to see if this guy was there to brush Douyin, but it turned out to be not, the mobile phone screen turned out to be a monitoring screen.

It turns out that this thief is still very dedicated, and the electric car that was launched just now is not a toy, but a small monitoring instrument, and this small monitoring instrument is helping this thief to observe the surrounding situation clearly!

Because it is now dark, the overall color of the electric car is also black, so no one found it for a while, at this time the thief squatted in place, muttering in a low voice: "From here to the wall inside, a total of thirty-two steps, the patrol team will patrol at a distance of thirty-two steps, a total of two groups of people, two groups of people face each other together, patrol back and forth, they want to pass through this peripheral patrol point, enter the museum must use the blind spot after the two groups of patrol people briefly converge!" “

The thief watched the three seconds of blind time after the two groups of patrolmen walked in front of him, and one of them rushed up the high wall, jumped into the inside of the high wall of the museum, and followed by a few moves, and got into the museum house.

Immediately after jumping up, at this time, the Duke of Loren had put all the inside of the museum under martial law for the safety of the museum, and many mechanisms were activated inside the museum, and no one was left in the museum.

The thief smoothly blended into the museum, followed by taking out an infrared sensor camera from his pocket, this look, sure enough, the front corridor was covered with red lasers, this TV watcher knows, at this time it is a very common means to put in, infrared induction plus cutting.

At this time, the thief took glasses to see all the infrared arrangements in his eyes, followed by a burst of operations, and broke through the infrared surrounding, this Song Zihang had a toothache, saying that since you have arranged the infrared, can't you arrange the infrared rays a little more densely, it has to be scattered, it seems to be irregular, but it is full of loopholes.

If this infrared is arranged by Song Zihang, it is very simple, directly arrange an infrared ray every five centimeters in the outermost periphery, I don't believe that there are still people who can break through the past, Song Zihang shook his head.

At this point, the thief continued on his way, and soon entered the interior of the museum, where he saw a famous painting covered in a glass cover in the center of the museum.

At this time, the thief quickly ran to the famous picture, and after a closer look, he saw the words "Female History Portrait" written on the famous painting.

"Great, I finally found you, hmph, you robbed us of Huaxia's things, let me steal it back for Huaxia!"

The thief muttered, and then reached out to open the glass cover, but with all his might, it turned out to be empty, and he couldn't open the glass cover at all, the thief was stunned for a moment, but immediately understood what was going on, so he wiped his pocket, and the next moment a white sound box appeared in the thief's hand, and the thief put this on the glass cover, and then listened to the prompt sound.

"Dingdong, the password lock has been connected, the password is cracking, the password is cracked, 90 percent, 80 percent ......"

The white audio box made a crisp sound, but the sound was not loud, not enough to alarm outsiders, but it still startled the thief in a cold sweat, the thief looked at the audio box at this time, and he was angry, and he couldn't let David, the bastard, come casually, this password cracker is good, but what the hell is this voice prompt, the old lady is a thief!

David, known as Stilwell David, is a super genius from the Stephen family in Europe, and he has an uncle, who is world-famous, is the legendary bigwig, Stephen Hawking.

The thief muttered, followed by the security system that Duke Loren had spent tens of millions of dollars to purchase, and the glass cover opened, revealing the picture scroll inside, the thief was excited, and reached out to pick up the picture scroll, but as soon as he picked it up, a spring button pressed under the picture scroll suddenly popped up, and the alarm went off in an instant.

At the same time, a series of anesthetic needles suddenly shot out from the two pillars close to the thief, the thief dodged flexibly, front flip, back flip, Thomas spin all the way, a series of movements, and finally was stabbed in the arm by an anesthetic needle, the thief was startled, quickly pulled out the anesthetic needle, and then ripped off a piece of cloth, and stuck his arm to prevent the anesthetic from flowing back to the heart with the blood!
