Thinking of soul cultivation, Tian Xu couldn't help but think of Zhou Aiping, who had occupied the territory of the Three Immortals Temple and was about to cross the catastrophe: "I don't know what happened to Aunt Zhou." During this period of time, I have not seen the golden light of the success of the transitional tribulation, nor the blood light of the failure of the tribulation, so it should be that there is no tribulation yet. But after thinking about it, I felt that there was another possibility: "Could it be that I was robbed when I was in the Sea King's Palace?"

I am far away in the Americas now, and I have no time to take care of domestic affairs, even if Zhou Aiping survives, I can't help, it's useless to think about it, it's better to rescue my sister as soon as possible, and then consider returning to China to unify the cultivation world and confront the demon sect after finishing the matter here.

Putting aside these miscellaneous thoughts, Tian Xu flew at full speed towards the Central Valley of California, where Julianne was located. Montana is the northernmost point of the United States, thousands of kilometers from California in the southwest, and it takes about three hours for ordinary people to fly by airliner. Tian Xu's flight speed was much slower than that of a subsonic jet, and after just over an hour, he became a little impatient: "If it goes on like this, how long will it take to fly to California? Maybe when I get there, the monsters will have already eaten and wiped out." ”

But in a hurry, the flight still has to continue, and I can only find a way while flying.

"It would be nice if there was a blackbird," Tian Xu said to himself. The Blackbird is an ultra-high-speed aircraft developed in the United States that can reach speeds of more than Mach five and fly from Montana to California in less than an hour. But now that all the Blackbird planes of the US military have been decommissioned and destroyed, where can he find one that can fly? In addition, even if the United States now has a fast enough plane or other means of transportation, how can he contact the other party to help him? When things are connected, he will probably be able to fly two round trips from Monta to California.

As Tian Xu flew, he was quickly thinking about ways to speed up the flight in his mind. The flying formation he is using now was originally figured out by himself when he was just condensing the pill, and although it has been improved several times later, it is not long after the establishment of the flying formation.

Since he went to sea to the Americas, Tian Xu's realm has improved rapidly, and he has experienced several major battles in a row, and his control and cognition of aura have obviously risen to a great height, although he has not studied the original flight formation carefully, he also intuitively feels that he is becoming more and more dissatisfied with the flight speed, and even a few times in the battle, in order to obtain a faster instantaneous speed, he has begun to use the method of stepping on the air to jump in the air through the method of chasing the sun. It's just that I haven't had time to seriously study it and improve it.

Thinking of the battle, Tian Xu couldn't help but think of the flying methods used by the enemies or friendly forces he had encountered. All Earth Immortals can fly, and the speed is not too slow, and it seems that flying has become a basic skill of Earth Immortals. It's no wonder that after all, the earth immortal is a body composed of aura, and as a mass of gas, if it can't fly, it can't be said at all.

It's just that the flying speed of the earth immortals is difficult for him to be satisfied with or envious, because even among the high-level earth immortals in the Holy Realm, he has never encountered a faster speed than him, and he really has no interest in spending time pondering.

Suddenly, Tian Xu had an idea, and thought of a person, who was Qin Gang who he met in the Sea King's Palace not long ago. At that time, Qin Gang used a large cylindrical shell as a thruster, and his speed was actually faster than him, and he also had one such shell in his hand, which he had taken from the sixth-level demonic beast that was chasing him when he was in the Thousand Islands.

Later, when he and Ziyan were ambushed and besieged by the masters of the Demon Gate in Vancouver, they also used that shell as an accelerator and achieved unexpected results. If this thing is taken out and used as a thruster, it should be able to increase the speed a lot.

Tian Xu's flight didn't stop, and with a wave of his hand, he took out the big shell from the Medicine King Bucket. This thing seems to have its own jet propulsion attribute, and if you let air pour in from the front, it will be sprayed out from the rear at high speed, creating a forward propulsion force.

Tian Xu's current speed reached nearly 100 meters per second, and as soon as the shell came into contact with the air after it was taken out, it was full of wind and flew forward. Tian Xu's power to grab the shell was not great, and when he couldn't catch it off guard, the shell flew out of his hand all of a sudden. It's not that Tian Xu can't grasp this shell, let alone that he can't adapt to the force of rapid acceleration, he was really worried that he would crush the shell with too much force, so he deliberately let go and let the shell fly out, and then set off to chase after it.

After the shell got out of his hand, it was not stable in the air, and soon lost its center of gravity, and its speed also decreased, and it was grabbed by Tian Xu.

"This thing is really good, it can be used as a thruster in the air or water, go back and attach a formation to control it, it should be able to make a good flying machine."

Tian Xu used a formation to attach a fixed structure to the shell, and then deeply fit with his body, and then carried the sutra behind his back.

After accelerating again, he immediately experienced the accelerating power of the shell, increasing his speed from less than 100 meters per second at the beginning, and later reaching more than 250 meters per second, which is close to the speed of sound at nearly 10,000 meters in the middle and high altitude.

At this time, Tian Xu noticed that the gas spewed out from the back edge of the shell was even stronger, and the edge of the shell had been heated to almost red by the friction of the air flowing at high speed, but the accelerating trend had not weakened in the slightest. The high-speed jets of air from behind the shells make a screeching sound, like the sound of a jet plane.

Tian Xu himself was not unaccustomed to such a high speed, but looking at the shell, it seemed that it was almost close to the limit of strength. If it is allowed to accelerate like this, it is estimated that it may be destroyed before it reaches the speed of sound. Even if the shell barely withstands it, when it reaches the speed of sound and breaks through the sound barrier, it will be smashed to pieces by the accumulated sound wave energy.

He had to use the formation to carefully control the total amount of air flowing into the front of the shell, suppressing the speed of flight below 280 meters per second, and basically guarding the shell from the influence of excessive speed.

This speed has already made Tian Xu more satisfied. His current speed is about the same as that of a jumbo jet, or even slightly faster, which is an absolute high subsonic. At this speed, it is estimated that it will take more than an hour to reach California.

Now this shell as a flying machine, there are still a lot of flaws, including the strength is too low to achieve supersonic speed, and it can only fly in the air, in outer space, which is almost vacuum, because there is no gas to eject, it cannot be used as a power for flight.

However, these deficiencies are not unsolvable. Tian Xu is going to study this thing when he has time, and then find a way to use the formation to transform it, and truly transform this shell into a flying magic weapon, which should be able to be used to meet the needs of daily use. He also wanted to learn from the jet principle and improve his flying technique. His ultimate goal is definitely not to rely on any magic weapon to achieve his own flight, skills like flying must be based on his own ability, and cannot rely on external things.

But now he can only think about it, he now has to rush to the Central Valley of California in the shortest possible time to find his sister Julianne.

The terrain of the United States as a whole, in the simplest terms, is mountainous in the west, and vast plains and hills in the central and eastern parts of the United States, which gives the United States a huge area of arable land. Unlike most states in the center and east, California is located on the westernmost side of the United States, and is located in the south, with almost the entire state located in the coastal mountains of the western coast.

In the middle of California, there is a long valley with relatively flat terrain, which has been transformed for more than 100 years to become the most expensive agricultural land in California and the United States. On the one hand, the land here has the best water system in the world to maximize the annual harvest, and on the other hand, it is related to the scarcity of agricultural land in California. On the other hand, it's a grape-friendly area, and there are vineyards that produce world-class wines, and these vineyards are expensive.

Xu Jingyi owns more than 800 acres of vineyards here, and CCB's Valley Winery within the vineyard produces some of the best wines in the United States, earning an astronomical amount of money every year. Although the 800 acres of vineyards are very small compared to the tens of thousands of acres of Montana ranches, their annual production value and their own value are far from those of ordinary farms and pastures.

Tian Xu's sister Julianne is now trapped in this valley winery.

Tian Xu only roughly knew that the Valley Winery was in the middle and south of the Central Valley, but he didn't have much impression of it. Compared with the impressive Montana ranch, Tian Xu didn't like the environment of the winery when he was a child, so although he would visit Xu Jingyi's house in the United States every year when he was a child, he rarely went to the winery.

This time he came to save Julianne, and he only had Julianne's approximate location in his hands. Originally, he could have used the electronic map to do accurate positioning, but I don't know if it was the impact of the Demon Gate outbreak, the electronic map in the United States is running extremely slowly, and the network is intermittent, and the positioning operation has become less reliable.

Now holding a tourist map of California in his hand, Xu Jingyi circled a location with a pen on it, which is the coordinates of the valley winery, as for the landmarks that can be used for reference, they can only be found by Tian Xu himself, in short, it is not so reliable.

Fortunately, before Tian Xu took out her hair from Monta, he obtained a sample of Julianne's scent from her bedroom, and also got a recent photo of her, so that he could find her specific location through the smell. Relatively speaking, Tian Xu believes in his sense of smell more, his olfactory imaging can already detect a range of more than 100 kilometers, and when he reaches the location marked on the map, he can find the traces of Julianne herself or her past stay or activity at the first time through olfactory imaging.
