The pilot followed the expedition for two days, and Professor Serizawa asked him to go back, which was useless because there were too many people.

The psychological quality is not enough, and it is an unstable factor to insist on following, and maybe when the mentality explodes, he will suddenly attack the crowd with a submachine gun.

This kind of thing has not happened before, and this kind of companion is sometimes more dangerous than a wild beast.

The pilot also took a female graduate student, the girl graduated from Harvard, a typical top student, the girl is the same age as Bella, usually very sunny and optimistic, and the two-day trek in the underground cave made this optimistic girl almost have a nervous breakdown.

The psychological quality of the male doctoral student is somewhat worse, and the big man enlightened him for a while and persuaded him to go back.

In the end, the team was left with Professor Qin Ze, Old Joe, Big Guy, Bella, and Shaw.

Professor Qin Ze has a firm belief, Lao Qiao doesn't care, it doesn't matter if he dies in an underground cave, and the remaining three are really not afraid.

Got rid of the three rookies, and the team was two percent faster.

That's ten days.

"Die!" The big guy clung to the serpent's tail, Bella nailed it to the jaw with a sharp knife, and Shaw stabbed the serpent in the head with a tactical straight knife.

Fearing that more monsters would be drawn, they didn't dare to use guns.

It took a lot of effort for the three of them to kill the giant snake next to a water source in the underground cave.

After filling the water bladder, he walked in the dead underground passage for another five days.

At this time, they were all about to leave in a daze, and after walking for seventeen days in a row, Bella still did not perceive the end of this passage.

They only know to go down, to the south, in a dark and oppressive environment for a long time, except for Xiao, even Bella is a little bored.

When does this have to go?

As the physical strength of the people was rapidly depleted, the demand for water began to increase, and on the seventh day after killing the giant snake to fill the water bladder, the drinking water was exhausted.

Professor Serizawa and Lao Qiao also wanted to go with them to find water, but the three of them hurriedly refused, don't let you see those more murderous pictures!

Stop and go, on the forty-seventh day of entering the underground cave.

"There's hot air, and the exit should be right in front." In the quiet environment, Bella spoke abruptly, and several people were first surprised, and then delighted.

They walked for another day, and the cold light from the rock wall made several people turn their heads in unison.

The light is too strong and they spend a lot of time in the dark, and it takes some time for their eyes to get used to the light.

It took them a lot of time to get used to it, and when they walked out of the cave, they were surprised by what they saw.

In the distance, there was a tall volcano, full of towering tropical trees and strange plants all over the mountains, and on the right hand side of Bella there was a waterfall with a drop of more than 100 meters, and the strong light passed through the waterfall, and a brilliant rainbow was erected not far away.

"Is this the mysterious island in Verne's book! It's a lot more than I expected?! ”

Old Joe shouted happily, and the rest of the people looked excited.

Only Bella was looking up at the sky.

Walking all the way, you can more or less see some of her strangeness, not to mention anything else, walking underground for a month and a half can still keep it relatively clean, and there is no bad smell on the body, this is not something that ordinary people can do, Professor Serizawa also followed her line of sight.

"Miss Swan, what do you think is wrong?"

The Japanese professor's words silenced several people.

Bella pointed to the sky and around, "It's really weird here...... Professor, I'm afraid this place is not what you expected. ”

She was sure that this was not the underworld, and the source of light in the underworld was definitely not the sun, but ...... She felt that Professor Serizawa was probably going to be disappointed, and everyone walked around, and they might be back to the surface.

Shaw hated the sun, he didn't like it when he was an agent, let alone this half-spirit state now.

After a general look, he shook his head, indicating that he didn't see the problem.

The big guy watched it carefully for a while.

Bella looked at Professor Serizawa, "Professor, I heard Vivien talk about your short experience underground, it doesn't look like it's underground, we seem to be out again." ”

Professor Serizawa stomped the dirt under his feet hard: "You say...... You say we're back on the surface? So what is this place? Where are we now? ”

He immediately opened his backpack: "Quick, let's use the calculation method of spherical triangles to see where we are now." ”

Instruments are not reliable, and in many cases mathematics is the tool for identifying directions.

Bella and he began to calculate.

Calculate your height first, calculate the length of your shadow, and then substitute the time and date to calculate your location.

After calculating the results twice in a row, Bella was stunned: "Professor...... Are we in Antarctica? ”

Palau is in the western Pacific Ocean, not in the Antarctic at all, starting from the mysterious island shrouded in tornadoes, no matter how you go, you will not go to the South Pole!

After 48 days, he walked from Palau to Antarctica, which sounds like nonsense.

Professor Serizawa looked at the passage behind him, and then at the sun hanging high in the sky: "If this conclusion is true, then find out the reason why the Titan Behemoth can travel quickly underground, and the passage from Palau to the South Pole will not be the only passage......"

Professor Serizawa sat on the ground, pondering the implications of this incident for himself and the many theories of the Imperial Plan.

Bella didn't discuss any scientific issues with the bitter professor, but returned to the ground, and a large rock in her heart was removed, and once she was released from the forty-eight days of hard trekking, her heart was so light that even the shackles that had imprisoned her from the fifth ring to the sixth ring were loosened a little.

Those monks practiced penance at every turn in order to break through for themselves, and I have to say, it makes sense.

The joy on her face was almost uncontrollable.

She looked left and right, and then rushed into the dense forest on the side, and after a short time, she grabbed two baby elephants with one hand.

"These guys have been staring at us just now, hehe, help me get one, I'm going to take it back when I go back!" The baby elephant was the size of a normal domestic cat, and Bella clutched the baby elephant's belly, and the baby elephant's four little short legs struggled desperately, and the nose and tail flicked non-stop.

Bella handed one of the baby elephants to Shaw and took it and played with it!

Before, she thought that Arendelle was missing something, a lot of little foxes, little squirrels, and little rabbits, and she didn't usually look closely, but now she found out that there had been a lack of some baby elephants!

Catch it back and play with the kids! Of course, she and Natasha can also play along.

Xiao touched the baby elephant's belly, tugged the baby elephant's nose, pinched the tail and ears, even if she didn't have feelings, she felt very funny at this time.
