Yu Bai clenched his cheeks, his eyes were firmly fixed on the light path of the deputy boat, and he couldn't count how many breaths it was.

When he saw a small bright spot suddenly appear in the inky darkness, his entire shoulder collapsed.

His heart was still beating violently in his chest, and he closed his eyes slightly to relax himself.

The gray mist swept in almost immediately after that little light.

"Let's go."

The gray fog completely enveloped the sub-boat. Yu Bai didn't even have time to glance at Scarlet Silk before he pressed the start order.

Scarlet sat down at the bubble ball suction port, squeezing down the gasp of breath.

Theoretically, when the bubble ball is retracted, people will not feel the pressure difference, but people with little experience or sensitive constitution will feel it, and most people will also have a period of dizziness after being sucked back out of the bubble because of the inevitable floating of the sea working environment.

Scarlet's dizziness is even heavier.

She knew that it was because of Fang Cai's intense brain power to manipulate the three hunters.

She had to blink, then stand up.

Yu Bai sat in front of the control screen with his back to her. "How?" He asked, hearing movement from behind him.

"Took it out...... Core pieces. Scarlet took a breath and sat down, seeing for the first time that Hill No. 1 had withdrawn from the foreground, and at this moment, along with several surrounding hills, was pouring ash from the surface of the mountain.

"Thank you."

Yu Bai was busy operating, and only responded after a while. "Thank yourself. You said that I could fly out of the landslide of Yubongling, so it gave me the confidence to fly out of Hill No. 1. ”

After speaking, he turned his head sideways, glanced at Scarlet Silk quickly, and then turned back solemnly, staring at the control screen.

Scarlet gently tugged at the corners of her mouth, and now she didn't even have the strength to laugh.

It's not a good time to laugh either.

They had only just left the area around Hill No. 1, where the ash had collapsed, but swirling currents rose from each of the hills that swept in front of them.

Yu Bai drove the auxiliary boat and rushed through the whirlpool columns. Fine-tuning and avoiding, the tossed knolls behind them rolled up the sedimentary ash one by one, and then shook them like the end of the world.

The eraser followed them.

The eraser will catch up with them after five minutes. The simulation results are very clear.

"Yu Bai." Scarlet gritted her teeth and took a deep breath, "I'll come." ”

"It's already the maximum speed."

"I'll come, we'll go the other way."

"Huh?" Yu Bai narrowly let go of a swirl and turned his head to look at her in surprise.

Scarlet led a route directly on the control screen.

"There's a big turbulence there."

"It's turbulence." Scarlet's gaze was firm, "Let's go from it." ”

"What?"

"There are tunnels there that lead to the vicinity of Keith One Station."

"Can you wear the co-boat?"

"Find the right way, and you'll be fine."

Yu Bai glanced at her again, and without hesitation, he swooped the auxiliary boat and flew to the turbulence.

"You are familiar, you find the way, I control the boat." He said loudly.

"Okay."

It was a valley five knolls away, and the half of the mountain next to it seemed to be missing a chunk. Yu Bai could see on the control screen the shape of the gap after the seawater was perceived, just like a half-arch.

The water was frantically twisted into a bully flower there.

There is no turning back.

"Did you find your way?"

"You have to go inside to confirm the previous detection map, and now you can't start the field exploration."

"What?"

Yu Bai almost turned his head to look at Scarlet, he stiffly controlled his neck, staring at the whirlpool mouth in front of him with wide eyes.

——————

"I'm going crazy." He faced the black whirlpool, which was darker than the outline of the kon, and cried out viciously, "Let's go crazy together." ”

The splash of water fills the close-up window picture like crazy.

The rest of the dark blue control screen is still running data quietly.

The contour perspective of the tunnel is drawn to the surface section by section.

"Left." The slender finger pointed to the next fork.

Yu Bai finally couldn't help but turn his head sideways, glanced at Scarlet, and said stiffly: "Have you been here, or have you not?" ”

"Sorry, I didn't come." Scarlet stared at the control screen, thought for a while, and guided the lower fork in the road, and said lightly, "If you control the boat, pay attention to the branch hole next to it, and don't be sucked into it." ”

“…… Good. Yu Bai suppressed all his messy emotions and immediately focused.

The route is designed to be lengthened in an orderly manner.

After passing through several branch tunnels, Yu Bai quickly adapted to the skill of driving the passenger boat in the depths of the tunnel. Only then did he have time to browse through the other data.

For some reason, the image of the mound outside the tunnel has not been updated, and it has remained completely gray.

The auxiliary boat is speeding through the tunnel, and the wall of the cave after the perspective is strangely shaped, sometimes large and sometimes small, and the sea water is pushed towards the cave wall, and then it is bridged.

All this outside should have happened in a turbulent and agitated manner, but there was no sound at all.

The boat was also silent.

Yu Bai swept towards Scarlet again, her eyes narrowed and sat in front of the dark blue control screen, her side face was calm, drawing her road map one by one.

"Are you having trouble?" Yu Bai wanted to make a sound.

“…… I'm afraid there is. Scarlet looked up.

"I'm just asking." Yu Bai's heart sank, and he tried to smile, "Don't look at me with a consultative eye, I'm blinder than you here." ”

"Finally, there is a shortcut, which is the most suitable and time-saving, but the auxiliary boat can't get through."

"What about the long way?" Yu Bai's first reaction was, "If you bend a little bit, do you have time?" ”

"There is no slight bend, there is a path that the auxiliary boat can take, turning north to the sea erosion valley, and then turning back to Keith Station 1 along the Keith Ridge, there is no time at all."

"Sea Erosion Valley?" Yu Bai felt that the name was very familiar, "Close to Keith No. 3 Station?" Do you manage the special landscape? ”

"Yes, the sea mound cave near Keith No. 3 station is the most accessible, and the exits are dense, so it is named Sea Erosion Valley."

"Is there a boat on Keys III?" Yu Bai immediately asked.

"Yes. But no. ”

"Why?"

"First, as already said, there is not enough time. We're now close to Keith 1, and if we turn north, we're definitely going to encounter a shock current. ”

"Second, the direction is not good. The hydrothermal fluid originates from the northeast to Taihara, and the impact of Keith-3 station will be much greater than that of Keith-1 station. ”

"Also, even if we were lucky enough to get to Keith III and change to the reserve boat, after crossing the Keith Ridge, it would still be pinned down under the Caderyo Belt and could not dive, and at that time the shock current happened to be combined with the solar tide, and we had no chance at all."

Yu Bai's thoughts turned sharply. "Can we hide at Keith III for a while? Isn't it possible for the Observatory to accommodate people in need? ”

"No, all the observation stations along the Keith Ridge are now level four, they don't meet the standards of man-machine attendance, and there is no life-sustaining support system," Scarlet explained quickly, "Every time we go, we borrow the life-sustaining resources of the Poseidon chariot. ”

"Where's the ship? The reserve boat has life-sustaining resources, and we have a new backup boat, how long can it be supported? ”

Scarlet was silent.
