Don't wait to say that the world of cultivating immortals is wonderful, there is not much difficulty in crossing space, Xu Hao only needs to use mana to create a shield to protect his body, and even mana does not consume much, after all, flying with mana, there is not much difference between flying sideways and flying vertically, and as long as he flies out of 300 kilometers, it is basically considered to be in outer space.

And when it comes to outer space, it is even simpler to fly, because there is no gravitational attraction, Xu Hao can continue to accelerate without consuming much mana, and soon his speed will reach dozens of times the speed of supersound, which is electric on the ground, but it is nothing in outer space, basically the speed of any object is dozens of times supersonic speed.

Xu Hao flew for a long time, constantly using his own radar to locate his position in space, and the coordinates he used to locate were the world of Daqi, he knew that with the help of modern experts, he learned a set of methods to calculate the distance between himself in space and the earth, he came to the orbit of the synchronous satellite and began to slow down constantly to keep himself in this orbit, outer space is the most troublesome, it is easy to rush, but it is very difficult to stop, Xu Hao said a lot of mana to let himself stay in the orbit of the synchronous satellite.

The geosynchronous satellite is a geosynchronous orbit satellite, also known as a geostationary satellite, which is an artificial satellite operating in geosynchronous orbit, the altitude of the satellite from the earth is about 36,000km, the direction of the satellite is the same as the direction of the earth's rotation, the orbit is a circular orbit located on the earth's equatorial plane, the period of operation is equal to the time of the earth's rotation of one week, that is, 24 hours, the orbital speed of the satellite in orbit is about 3.1 km/s, which is equal to the angular velocity of the earth's rotation. By deploying three communications satellites in geosynchronous orbit, global communications can be achieved except for the two poles.

This is set by experts to help Xu Hao, in this position, as long as Xu Hao places the reconnaissance satellite in this orbit, and then the camera is aimed at the lair of the Blood Demon Ancestor, he can monitor the Blood Demon Ancestor 24 hours a day.

Of course, Xu Hao is an artificial satellite, so the lens of the monitoring satellite has to be adjusted by himself, and the speed of the satellite flight has to be pushed by Xu Hao himself, because the satellite is not enough to go to space, it also needs to orbit around the Daqi world at a speed of 3.1 km/s, and this speed needs to be provided by Xu Hao himself, not too fast, not too slow, if it is too fast, the satellite will rush out of orbit and drift to other places in space, and if it is too slow, the satellite will be attracted by the gravity of the Daqi world to become a meteor!

When all this is done, Xu Hao can fly towards the ground!

Half a day later, Xu Hao landed like a meteor in the wilderness of Yuzhang County!

"Finally back! The environment in the sky is terrible, it looks like it's being confined! "A heaven is equivalent to the distance that Xu Hao has circled the earth twice! But this distance is not as large as the diameter of a grain of sand to the universe!

Then Xu Hao returned to the back mountain of Qingniuguan, where there is Xu Hao's signal receiver, which can receive the picture of the satellite in the sky! Of course, because of the rotation of the planet, most of the time Xu Hao could not accept the signal of the Dao satellite.

And at this time, it reflects the superiority of the world of cultivating immortals, with such a plug-in as mana!

Xu Hao took a magic weapon in the satellite, refined the satellite with his own divine thoughts, and even used his divine thoughts to stay on the satellite, so that when the signal receiver could not receive the signal, Xu Hao could use his mana to receive the picture seen from the reconnaissance satellite!

Of course, the satellite is at an altitude of 36,000 kilometers after all, the distance is too far, Xu Hao wants to control the satellite at this distance, and it will consume all his mana in about 10 minutes, so until the last resort, Xu Hao will not use his divine thoughts to control this satellite! Xu Hao can only wait for modern society to create a relay satellite to help him relay the signal of the satellite.

Satellite Signal Receiving Station!

Hongyuan and Qingniu are here!

When they saw Xu Hao coming back, they immediately asked, "Can these agencies really supervise the Blood Demon Ancestor?" ”

Xu Hao went to put the satellite, and the placement of Xu Hao here was handed over to Hongyuan and Qingniu. It's just that they didn't believe that such a machine could see the Blood Demon Ancestor thousands of miles away, so they immediately asked Xu Hao as soon as they saw him come back.

"Of course, these are one of the most powerful magic weapons in my hometown!" Xu Hao turned on the machine, and soon the receiver began to display the picture, Xu Hao used it to start connecting to the satellite, and soon the picture of the earth began to appear on it. A ball that is almost the size of a jewel!

Hongyuan was shocked when he saw the real picture: "This is the world we live in? ”

Xu Hao nodded!

Qingniu sighed: "I used to hear the monk say that the earth is a spherical shape, and Lao Niu never believed it, thinking that they were fooling, but today I finally saw it." ”

Qingniu continued to ask, "Where are we in Daqi?" ”

Xu Hao said: "This is going to expand the picture!" ”

Soon the sphere grew larger and larger, and the outline of the continent began to appear!

Large lakes and rivers are also beginning to appear!

"This is the North Sea, the Yellow River!" Hongyuan continued to exclaim, he can really see the scenery of Daqi here, this is simply an immortal weapon, what kind of satellite can actually monitor the entire world, what is this not a fairy magic weapon?

Soon Xu Hao positioned the Heavenly Demon Mountain! The reconnaissance satellite brought back by Xu Hao is the most advanced in the Celestial Empire, with a resolution of 0.01 meters, which can see anyone on the ground clearly!

Therefore, after Xu Hao continued to enlarge the picture, he soon even saw the picture of the cultivation of the demon sect disciples on the Heavenly Demon Mountain!

Qingniu was shocked and said, "You can see it so clearly!" It looks like a Skeleton Ancestor! Even the third-grade monks can supervise it, Xu Hao, your immortal weapon is too powerful! ”

And at this time, the skeleton ancestor on Tianmen Mountain looked at the sky suspiciously, he seemed to feel that someone was watching him just now, but he couldn't perceive anything, "Is it an illusion!" ”

Qingniu was startled by the Skeleton Ancestor's movements and said, "This Skeleton Ancestor won't find out that we are monitoring him!" ”

Hongyuan said worriedly: "It should be, a top-level cultivator like Skeleton Ancestor has a strong divine perception of divine thoughts, and it is difficult for our supervisors to hide his perception!" ”

Xu Hao said: "The satellite is tens of thousands of miles away, even if the Skeleton Ancestor perceives it, there is no way to take the satellite, with the satellite, we can monitor the actions of the entire Demon Sect in the future, and we no longer have to worry that the Blood Demon Ancestor will suddenly sneak attack our Qingniuguan." ”

Qingniu was pleasantly surprised: "Does this mean that we don't have to flee to Chang'an!" ”

Xu Hao nodded and said, "Of course!" And I'm still looking for a weapon to deal with the Blood Demon Ancestor, and it won't be a problem when I find the Blood Demon Ancestor. ”
