"Whew...... Hu ...... "Looking at the back of Huashan Courtyard getting farther and farther away, Qing Shui's brain began to lack oxygen, the whole world swirled in front of him, his vision was bright and dark, the portal suddenly closed, and his body suddenly fell backwards.

"This kind of thing is also common, it seems that I have to go first. Huashanyuan looked back at the black spots lying in the snowdrifts below, it was not easy for Qing Shui to climb here on the first day of cultivation, after all, this was the highest mountain in the world, and it was not so easy to conquer it easily.

I don't know how long it took, the clear water whose hands and feet were frozen slowly woke up, the air here is thin, even with the blessing of obsidian, it is difficult to maintain it here for too long, I really don't know how Huashan Temple climbed to that height without oxygen cylinders.

"Miss Shimizu, how do you feel?" The voice of Hanaya-in came to his head, and Shimizu had to continue to release the portal to catch up with him.

"What do you want me to ......"

"Listen to your voice as if you're about to run out of breath, try to find a rhythm to breathe, otherwise you won't be able to climb up like this." Huashanyuan's voice paused, and he didn't know if it was the lack of oxygen that made Qing Shui not hear his voice just now, "Forget it, let me teach you." ”

"Why don't you come down and teach me?"

"No kidding, your mission is to catch up with me, I'm at the top of the mountain now, wouldn't it be easier if I went down to find you?"

"The top of the mountain?!" Qing Shui raised his head incredulously and looked at the towering peak, standing here he couldn't see anything at all, but the oxygen there was completely not enough for humans to breathe, how did that guy in Huashan Yuan talk to himself in such an indifferent tone?

"Okay, from now on, take a big breath, then hold it and change your breath every five hundred meters. ”

"Are you serious?" Qing Shui couldn't believe what he heard, even if he took a big sip of this thin oxygen, he might not be able to store much, not to mention that the portal could only move a hundred meters at a time, and each release would take a lot of physical strength, and it was impossible to do it in this state!

"Of course, Sojuro asked me to treat Miss Shimizu the way Orimoto-sama was trained, and that's how he trained me back then. Speaking of which, it was a few years ago, and at that time, like Miss Shimizu, I was very surprised to hear these words of Orimoto-sama, but it turned out that he was indeed a very good teacher. ”

Qing Shui silently took a deep breath, stored the breath of air that did not have much oxygen in her chest, and quickly opened the portal, and the moment she passed through the door, her chest seemed to explode!

"Hmm......"

"Miss Shimizu, I know it's difficult, but it's part of the training, and if you can make it to the top, it's a success in the first stage. ”

"Phase 1?" Qing Shui asked.

"Breaking through myself standing at the foot of the mountain, this is the first lesson. ”

Qing Shui seemed to understand something, and immediately took a sharp breath, she knew that the oxygen above would be even thinner than now, if she couldn't even cross this level, breaking through herself standing at the foot of the mountain would be just an empty word.

The portal unfolded, and the chest once again seemed to explode, Qing Shui endured the difficulty of declining physical strength and lack of oxygen, and forcibly cut the second portal and stepped in, the green tendons of her temples protruded, and her head was like an expanding balloon, and her vision gradually blurred, but she continued to cut the third door.

"It seems like I'm working hard. The Huashan Courtyard at the top of the mountain looked at the flickering light in the distance and smiled.

After crossing five doors in a row, Qing Shui's physical strength couldn't withstand this intense consumption, and she fell to her knees in the snow, her eyeballs began to be bloodshot, the muscles of her whole body were in a state of paralysis, and her feet could barely support her body to stand up.

"Miss Shimizu, your position should be three thousand meters away from the top of the mountain, and then, try to reach the top of the mountain in one breath. ”

"In one breath......"

"That's right, I think after passing through the five gates just now, you are the only one who knows your physical condition best, right?"

Huashanyuan is right, if it were an ordinary human doing that, he would probably have fainted due to lack of oxygen by now, but under the adjustment of obsidian, the respiratory system seems to be gradually adapting to this kind of high-intensity training, even if only a small part of the oxygen is absorbed, it can still breathe normally.

"I see. Qing Shui slowly stood up, his legs trembling from the cold and weakness, and a blue portal slowly formed under the white breath exhaled from his mouth, "It's really strict......"

At the same time, Okinawa Prefecture.

There was a thud from the invisible portal, and although it was only for a brief second, the strong sound wave was detected by the keel's instrument, and judging from the voiceprint, the sound was not made by a living being, but more like some kind of mechanical collision.

"Two groups, expanding the detection range of the instrument, groups one and three are ready to fight at any time. Nikaido looked at the empty sky, there was nothing coming out or anything entering, and there was no movement after the sound ended, but this was the first time in a few days that such a strange sound had been made, and it had to make people vigilant.

"Lord Fifth Rider, we detected a strange energy fluctuation to the northwest of the door!" the technical personnel in the rear suddenly reported loudly.

"Do you know what that is?"

"It's not clear, the components of that energy seem to be the same as the nature of the door. ”

"Is it something that can't be seen again......" Nikaido gritted his teeth and walked out of the door, only to see a transparent phantom suddenly flash in the air, although he didn't look very carefully, but with his perception he noticed that the thing seemed to come out from behind the door!

"Liya!"

"Got it!" Natsui seemed to notice the phantom flying into the distance, and ran quickly towards the plane, skillfully starting the engine and flying over Nikaido, leading him to the direction where the phantom had fled.

"Hey, what the hell is that?" Natsui turned on the positioning system and locked on the energy fluctuation just now, and at this time, Nikaido also came to the cab, staring at the transparent shadow moving at high speed in front of him.

"I don't know, anyway, we have to catch it. ”

"What?!"

"What's wrong?" Nikaido suddenly felt a shock from the plane, and then a forward force struck, and his whole body crashed into the joystick! At the same time, the plane's engine didn't know what was destroyed, and it suddenly lost power!

After stabilizing his body and looking out, he saw the plane hanging out of thin air, but the sound of the clatter from the shell could be faintly heard.

"Nikaido, it doesn't seem to be good......"

"Get out of here!" Nikaido immediately summoned Obsidian to cut through the body on the side of the plane and leap down.

As soon as the two of them left the cabin, the plane in mid-air was twisted into twists by an unknown force in the next second! The fuel tank and sparks caused a huge explosion, and the sound resounded across the sea, shaking a large area of waves.

"Whew...... Damn, it's a complete loss. Natsui emerged from under the surface of the sea, looked at the wreckage of the plane that had fallen not far away, and shouted angrily as he slapped the water.

Soon after, Keel's yacht came to the sea where the plane fell and picked up Natsui and Nikaido who had fallen into the sea.

Back on the shore in eastern Okinawa, the wreckage of the plane was also recovered.

"Nikaido-san!"

"Why are you here?" Nikaido looked at Mu Fengye and Sakuruma in the distance, and then realized that they had returned to Japan.

"We heard that something had happened at the connecting gate in Okinawa, so we rushed over, and it looked like it was too late. Mu Fengye looked at the wreckage of the plane on the shore, and really didn't know what could twist a plane like this, "Mr. Nikaido, what attacked the plane?"

"I don't know, I didn't see it either. The thing was as invisible as the Connecting Door, and it should be flying in the direction of Hawaii right now, but Letsuya had already picked up its energy fluctuations, and we could track it down immediately. ”

Sakuruma didn't pay attention to Nikaido's words, just looked over the crowd at the twisted wreckage of the plane.

"What is this?" Sakuruma crouched down and looked at the black substance in the water vortex dripping from under the plane, it looked like an obsidian molecule, but it had a different aura, anyway, it was not a matter from Earth.

"What are you doing?" asked Natsui, who was on the side, walking over and looking at Sakurama's findings on the ground.

"I think it's familiar, do you remember it?" Sakuruma picked up a stick from the beach and poked at the contents of the whirlpool.

"You say that......"

"Do you remember?"

"Not at all impressed. ”

"Forget it, it's better to ask for a piece of wood than to ask you. Sakurama threw down the stick, borrowed a special reagent bottle from the staff at the scene, and put the black substance into the bottle. But a minute later, Sakuruma noticed that the black substance had disappeared from the bottle for no apparent reason, and when she found it again, it was already stuck to the trunk of a tree in the distance!

"Fifth Rider, we caught the energy fluctuations obtained by the Seventh Rider in Mexico City. ”

"What?" Nikaido frowned and exclaimed, "It's only been twenty minutes, how can it be possible to cross the distance of half the world in such a short time...... Are you sure you read that right?"

"Yes, I'm sure. ”

"How, exactly?"

"I guess I used this ability. Sakurama came over with a reagent bottle.

"Where did you run just now?" Mu Fengye asked as she looked at Sakuruma who came from a distance.

"I found a very strange substance under the wreckage of the plane, and when I put it in this bottle, it suddenly shifted to the tree over there, and assuming that the substance could help the object move, then if enough matter was condensed to achieve teleportation over long distances. ”

"Sakura, you should have thought of something, right?" Mu Feng looked at Sakura's expression at night, obviously there was something else he hadn't said.

Sakuruma nodded and said lightly: "I'm afraid this matter has something to do with Yaotome......"
