Momo finally stabilized her mind, what happened suddenly just now really scared her enough, until this moment her face was still a little pale, and she kept trembling like a loving lamb.

But when she looked at Li Jun, she found that Li Jun seemed to be even more distracted than her.

"Brother Xiaojun, are you okay?"

Momo tugged at Li Jun's sleeve and looked Li Jun up and down worriedly, she was afraid that Li Jun would be hurt in the fight just now.

"I'm fine. Under Momodi's reminder, Li Jun came back to his senses and muttered a reply.

Wang Biao didn't really hurt Li Jun just now, he was just still in the shock of the beggar's shot.

"Let's go, accompany me to the bookstore first. ”

Li Jun glanced at the two Wang Biaodi's subordinates on the ground, and beckoned Momo to leave, compared to the matter in front of him, he felt that it was more important to determine the coordinates of the treasure first.

……

When she got home, Momo's computer had already arrived, and Li Jun helped her debug it and rushed into her room.

Coordinates are spherical coordinates that represent the location of ground points in longitude and latitude. The geographic coordinate system takes the earth's axis as the polar axis, and all planes passing through the earth's north and south poles are called meridians.

The intersection of the meridian and the ellipsoid of the earth is called the meridian or meridian. All planes that pass through the Earth's axis intersect with the Earth's surface to form an (elliptical) circle, which is the meridian coil. A meridian is a semi-elliptical arc.

The intersection of all planes perpendicular to the Earth's axis and the ellipsoidal surface of the Earth is called the parallel. The parallels are circles with different radii, where the parallels with the largest radius are called the equator.

On a globe, the meridian that passes through the original site of the Greenwich Observatory in London is called the 0 degree meridian, also known as the prime meridian. On the globe, the line parallel to the equator is called the latitude line, the latitude line indicates the east-west direction of the geographical coordinates, the length of all the parallels is not equal, and the degree marked by the latitude line is the latitude; The equatorial latitude is zero, north of the equator is the north latitude, and south is the south latitude.

On the globe, the latitude and longitude lines are intertwined to form a graticule, and the position of the point on the ground is represented by longitude and latitude, which is called geographic coordinates.

In order to accurately find out the coordinates given by the system, Li Jun went to the bookstore and bought a 1:100,000 world map, which is already the most accurate map he can get so far.

Li Jun prayed silently, hoping that the coordinates would not be in too remote places, and if they were too far away, it would inevitably be difficult to find them.

God seemed to hear Li Jun's prayers.

Seeing on the map that the location of the coordinates was on the outskirts of this small city, Li Jun couldn't help but breathe a sigh of relief. If the coordinates are located abroad or on some unknown island, it can be a headache.

"What could it be?" Li Jun couldn't help but be full of longing for this so-called treasure.

When the coordinates were not confirmed, although he was also looking forward to it, it was just expectation, and now that he knew that the treasure was so close to him, he was naturally even more impatient, and he couldn't wait to take the treasure in his hand immediately.

But things often backfired, and just when he wanted to go out, there was a sound of the door opening the door, and it should be his mother who was off work.

"Xiaojun, come out to help greet your Uncle Zhang and Aunt Wang, I'll go cook. Mother's voice came. Not only her mother herself, but she also brought her colleagues to her home as guests.

Li Jun sighed, he will definitely not be able to go out today, so he can only give up for the time being, and wait for his mother to go to work tomorrow before making plans.

"Uncle Zhang, Aunt Wang, you sit down first, and I'll pour you tea. Li Jun greeted the two warmly.

"Good boy, you're welcome, it's not the first time we're here, let's get it ourselves. Aunt Wang replied with a smile.

Uncle Zhang didn't answer, but stared at Li Jun with straight eyes, and muttered in his mouth: "Strange, it's really strange, how can there be such a thing." ”

This kind of look made Li Jun uncomfortable.

Li Jun has never liked Uncle Zhang. It's not that this person is like that, it's purely Li Jun's own feelings.

Uncle Zhang likes metaphysics and always chatters, and Li Jun has always believed in this, which may be the reason why he doesn't like Uncle Zhang.

"Lao Zhang, what are you doing standing? ”

Li Jun's mother happened to come out of the kitchen at this time, and when she saw Uncle Zhang's abnormal appearance, she couldn't help but ask aloud.

"Xiaojun, has anything strange happened recently?"

Hearing his mother's words, Uncle Zhang did not respond, but rushed to Li Jun in one step, grabbed Li Jun's hand, and asked eagerly.

Such a sudden move startled Li Jun, and he couldn't help but take a step back, wanting to withdraw his hand from Uncle Zhang's grasp, but he didn't twitch after a twitch, and he didn't know where Uncle Zhang got so much strength.

"Uncle Zhang, what's wrong with you?" Li Jun was still trying to break free.

Mother and Aunt Wang also didn't know why, they looked at Uncle Zhang in a daze, not knowing why he was suddenly like this, and they didn't know how to react for a while.

"It's amazing. Seeing that Li Jun didn't answer, Uncle Zhang seemed to explain to everyone, and continued to murmur: "I've seen it in books before, but it's the first time I've really seen it." ”

Everyone present didn't know what he was talking about, and they all looked at him in confusion......
