When passing through San Francisco Bay again, Tian Xu couldn't help but sweep around this bay, and picked up a batch of high-value demonic beasts and put them into the Medicine King Bucket.

It is said that since he had a domain and carried the Medicine King Dou with him, Tian Xu had long since stopped picking and choosing when he collected the Demon Beasts and Demon Cultivators into the space. It's just that there are too many demonic beasts in San Francisco Bay now, and with his strength, he can't put them all away at all, so he can only pick those with high levels and special uses. Rao was so, in this long and narrow bay, the number of demonic beasts he had captured still reached an unprecedented number, and several mountains had been piled up in the Medicine King Bucket, and he himself was very tired.

Not far after San Francisco Bay, an extremely narrow peninsula appeared in the southwest corner of California, which clung to the west coast of Mexico and stretched more than a thousand kilometers to the southeast, like a long scimitar, guarding the Pacific side of Central America, so that the winding and thin land isthmus between North and South America was effectively protected, at least in terms of momentum. This particular peninsula is the California Peninsula.

The topography of the California Peninsula is so special, so that Tian Xu is extremely curious, he observes all the way from north to south, sometimes diving to the bottom of the sea, sometimes flying into the air, only to feel a chill rising from this peninsula, straight towards the Pacific Ocean, those demonic beasts raging along the coast of California, not many dare to go south to this side, only occasionally can meet a half, it is also a higher level, and all of them are fleeing in panic.

Although Tian Xu could faintly feel the huge pressure on this peninsula, he couldn't imagine that it could have such a great deterrent effect on the demonic beasts, as if this peninsula could bring them annihilation at any time.

This peninsula not only put a huge pressure on the demonic beasts, but also posed a relatively strong threat to him, otherwise he would not have this creepy feeling. Tian Xu couldn't figure out what kind of attack pattern it would be if this formation was activated, but one thing was for sure, this must be an indiscriminate attack, and it would be effective against both the Demon Gate and the Earth's native cultivators.

After switching between the sky and the sea a few times, Tian Xu noticed one more point, that is, the pressure of this formation is much greater than that in the air when it is in the ocean, and it seems that the attack of this formation is still mainly facing the ocean, which should be related to the fact that the demon gate fled into the ocean back then.

Tian Xu's curiosity was aroused, this formation was too big, and he couldn't see the whole picture at all. Then he leapt to his feet and flew high into the air, hoping to get a glimpse of the peninsula from the air.

But this peninsula is so big that Tian Xu flew to an altitude of nearly 30,000 meters, and he couldn't see it clearly, and part of the peninsula was still sunk below the horizon.

The air here is already extremely thin, completely unable to support normal breathing, and the temperature is as low as minus 50 degrees, but for Tian Xu, it doesn't seem too cruel, and it is completely within his tolerance range.

The air is thin in the high altitude, and the drag of flight is already very small, so Tian Xu's speed has further accelerated, reaching more than 400 meters per second, entering a supersonic state. At high speed, the extremely rare oxygen in the air was collected by Tian Xu's breathing, which was completely able to support his normal breathing.

In fact, after the whole body entered the state of Jindan, Tian Xu's body was no longer significantly different from the earth immortal, and the biggest difference between the body composed of aura and the ordinary body was that it was no longer necessary to provide energy for the body by digesting the organic matter in the food, but instead relied on the aura to provide energy. In other words, the earth immortals no longer need to breathe oxygen in the air to sustain their lives, they will not suffocate, and of course they do not need to eat food anymore, and they will not starve to death.

Flying, stealth, shapeshifting, doesn't need to breathe, doesn't need to eat...... All these qualities distinguish the earth immortal from the life state below Ning Dan, so it is called "immortal".

In terms of body structure, Tian Xu has already entered the ranks of this kind of immortal at this time, but he is reluctant to give up his appetite and deliberately reserves the ability to eat and digest for his body.

It was already evening, and the sun had already set. When Tian Xu flew into the sky at a very fast speed, the sun, which had long since fallen below the western horizon, appeared in the sky again, and continued to rise as Tian Xu rose.

When Tian Xu raised dozens of kilometers on this basis, he could already faintly see the arc of the earth. At this time, the west coast of North America, located directly below Tian Xu, was already in deep darkness, while in the far west of the Pacific Ocean, there was a crescent-shaped area that was still sunny. At this time, the sunlight is projected on the sea water at a very small angle and is reflected again. Because the angle of incidence is so small, the sunlight almost reaches the level of total reflection, making the little point above the bright crescent moon facing the sun shine brightly, and it is extremely bright.

As Tian Xu ascended, the crescent moon became wider and wider, and the dividing line between day and night between the bright crescent moon and the large area of darkness became clearer and clearer.

This is the first time that Tian Xu has come to such a high altitude, and looking down on the earth from here, it is completely different from the feeling of being on the ground, this is a kind of perspective that seems to be God, and from this angle, all the efforts to fight and survive on the surface of the earth seem to become extremely small. He suddenly had a feeling: "The fairy world looks at the earth, is it like me, like watching a group of ants crawling on top of apples? Is this hidden space we are in now like an ant nest hidden deep underground, if it is dug out, the fairy world will let us disappear if we step on it casually? We don't even need to dig it out, as long as the fairy world discovers the location of our ant nest, whether it is pouring water in, breathing fire, Poison gas comes in, or cement seals our entrances and exits, or we get an anteater over, and we'll be done in a very short time. ”

Thinking of this, there was a chilling sense of terror, but Tian Xu quickly realized the pessimism of this feeling, and changed his mind in time: "This is my world, it is my duty to destroy the enemy and protect the earth!"

At this moment, Tian Xu saw an artificial satellite flying not far from above. It was supposed to be a near-Earth satellite, much faster than he could fly, and the lights on it flashed and flashed through the sky. Tian Xu looked down at the dark and dreary earth below, and couldn't help thinking: "The United States is the most developed country on the earth, and the satellite photos I have seen before, the night of the United States is a sea of lights like a galaxy, but at this time, the land under your feet is dark. He looked to the east, and could see a faint light, but it was not bright. From here to the east, it should be the territory of Mexico, and to the northeast, you may be able to see Texas, which is also a relatively desolate area in the United States, since you can see the lights, it means that it should not be overly infested by demonic beasts.

Tian Xu withdrew his gaze from afar, changed his body into a prone position, and looked at the California Peninsula below at the most convenient angle. At this time, he was at an altitude of 100 kilometers, and he could probably see the surface of the earth more than 1,000 kilometers away. The California Peninsula is a little over 1,000 kilometers long, and it is already relatively easy to see the whole peninsula. The sky on the peninsula has completely fallen into darkness, and Tian Xu's domain is completely unable to help him observe, but his olfactory imaging can extend to nearly two hundred kilometers away, although the main sense of smell that constitutes olfactory imaging is completely incapable of exerting because of the near-vacuum environment here, but other senses can still play a role. His newfound ability to detect electromagnetic waves played a major role here, allowing him to see the peninsula below more clearly.

Looking at the California Peninsula from this angle, Tian Xu got a more intuitive feeling, just like he imagined at the beginning, this peninsula is like a scimitar out of the sheath in the hands of the giant of the North American continent, clinging to the body and disappearing, constituting a powerful deterrent to the enemy in the Pacific Ocean, perfectly guarding the southern part of North America and the northern part of South America, and even guarding the tortuous and weak Isthmus of Central America.

It's just that what kind of move this scimitar will be? Tian Xu was still puzzled. He tried to think of a variety of plans, but he felt that they were not reliable, or they were not lethal enough to justify this powerful deterrent, or they could not be implemented at all.

Since he couldn't find the answer for a while, Tian Xu didn't dwell on this point, he knew that the gap between himself and the seniors who built this formation was too big, and it was normal for him not to understand. He put the question aside and continued to fly high in the air, trying to test his limits and at the same time to take a closer look at the American continent as a whole.

After flying for a while, Tian Xu's heart moved, and Ziyan actually wanted to go outside to take a look. He was a little worried, there was still a big gap between Ziyan's realm and him, his body was still a mortal body, and he didn't need to breathe at all like him, and there was no oxygen here, and his breathing formation had no effect.

However, Tian Xu quickly thought of a solution.

He carried the Medicine King Bucket with him, and the Medicine King Bucket sometimes had endless air, and if the purple smoke could not hold his breath for a long time, he could also take in air from the Medicine King Bucket to breathe.

Now that he had a solution to the problem, Tian Xu explained to Ziyan, asked her to prepare her mind, and then pulled Ziyan out of the Medicine King Dou. Seeing the scenery in space, Ziyan cheered happily, but there was no sound at all, the sound could not be transmitted in the vacuum, this was not a joke, and they were immortal first-class characters who had no choice.

The method of exchange of ideas has long been practiced, and Ziyan immediately said to Tian Xu: "I can't imagine that the earth is so beautiful in outer space, I have never been here." By the way, how tall is it?"

Tian Xu said: "It's about more than 100,000 meters." ”

"It's only more than 100,000 meters? Why is it so low? Shall we fly higher?" Ziyan didn't have much concept of 100,000 meters, and just wanted to fly higher.

Tian Xu said with a smile: "Isn't more than 100,000 meters high enough? So let's put it another way, it's more than 100 kilometers high, doesn't that feel very high? And we're flying higher now." He pointed to the California Peninsula below and said, "Can you see that peninsula? What does it look like?"
