Giant Fish Survival: I Can Hear the Giant Fish's Heart

"I'm hungry, time to find something to eat."

The child's voice rang in Zhou Wen's head, and Zhou Wen immediately woke up from his sleep.

Since he was inside the stomach space and couldn't tell whether it was day or night, Zhou Wen followed the Leviathan's schedule. When the Leviathan slept and rested, he would sleep and rest as well, in order to ensure that his schedule was consistent with the Leviathan's.

The stomach wall space vibrated violently, and the phasic Leviathan began to move.

Because food and water were scarce, Zhou Wen ate only one piece of bread yesterday. When he woke up today, his stomach was growling with hunger. With no other choice, Zhou Wen ate another piece of bread and drank half a bottle of mineral water.

He now only has two pieces of bread and three bottles of mineral water left, which makes him very uneasy. If he doesn't find any food in the next box, he will be in danger.

"Hopefully, the next supply crate will contain food," Zhou Wen prayed silently.

After a while, the sound of seawater churning came from the direction of the esophagus.

A large amount of seawater rushed in. Having experienced the impact of seawater several times before, Zhou Wen had experience in resisting the impact of seawater. He protected the supply box with his body to prevent it from being washed away by the seawater, and the light from his headlamp illuminated the things that the seawater brought this time.

"It's seaweed."

Upon seeing seaweed in the seawater, Zhou Wen immediately opened the system interface, accessed the blueprint for the algae oxygenation tank, and clicked "build."

The next second, a blue light appeared, and the stones in the supply box flew out automatically, arranging themselves in the air to form a stone trough that was one meter high and half a meter wide.

Under the blue light, seawater is automatically poured into the stone trough, along with some seaweed. The seaweed takes root in the pebbles at the bottom of the trough, and its slender body sways gently in the seawater.

"That's it?" The production process was quick and rudimentary.

Zhou Wen didn't know if such a rudimentary device could actually produce oxygen, because according to his knowledge, algae need sunlight to produce oxygen, but there was not a single ray of sunlight in the space inside his stomach wall.

However, when Zhou Wen shone the light on the seaweed inside the stone trough, this doubt was dispelled.

Because at this time, tiny bubbles have already appeared among the branches and leaves of the seaweed in the stone trough, and these bubbles are the generated oxygen.

"It seems it can indeed produce oxygen." Zhou Wen smiled, then leaned over the stone trough, held his nostrils to the rising bubbles in the water, and greedily inhaled.

"Ah~, this refreshing scent, it smells like oxygen." Zhou Wen's face showed an expression of enjoyment.

However, he didn't actually feel anything; it was just psychological. The stomach wall space had just been filled with seawater, and the oxygen content was very high. The oxygen produced by the algae oxygenation tank was very low, so there was no obvious feeling when the oxygen was plentiful.

Soon, the seawater receded, revealing a large amount of seaweed. This time, Zhou Wenxue was more obedient. He no longer waited for the Leviathan to finish feeding before moving the seaweed to the digestive pool. Instead, as soon as the seawater receded, he began to pick up the seaweed and move it around.

The amount of food required for a Leviathan to transform into a human is two-thirds of the space in its stomach wall. This amount requires eating several times a day, and each meal brings new oxygen to the stomach wall space.

In this way, as long as he moves quickly enough, he won't fall into a crisis of oxygen deprivation like he did yesterday.

Although there was an oxygen generator this time, it was unclear whether the oxygen produced was enough for him to breathe. To be on the safe side, Zhou Wen used the method he had come up with.

This method is actually quite risky, because the transformed Leviathan will consume seaweed multiple times, and Zhou Wen will experience several rounds of seawater impacts. If he is accidentally swept into the digestive pool, then things will get really messed up.

Therefore, Zhou Wen had to act quickly and pay close attention to the sounds coming from his esophagus. As soon as he heard the sound of seawater, he had to move away from the digestive tank immediately.

Zhou Wen started running back and forth. Fortunately, he had been running every day before he transmigrated, so his stamina was still good. After going back and forth more than ten times, he finally managed to throw all the seaweed he had eaten into the digestive pool.

"Huh~."

Zhou Wen lay on the algae oxygenation tank, breathing heavily. Because there was little seaweed this time, there was still plenty of oxygen in the stomach wall space. After breathing heavily for a while, the rhythm of his lung contractions slowed down.

After a while, the transformed Leviathan started eating again, and Zhou Wen had rested enough. He then began moving seaweed again, just like before.

The Leviathan fed five times in total, with short intervals between each feeding. Zhou Wen was exhausted from running back and forth constantly, and he was starting to feel physically drained.

After the entire feeding phase of the Leviathan transformation is completed and it enters the digestive phase, there is still about one-fifth of the seaweed remaining in the stomach wall space.

However, Zhou Wen was not in a hurry at all, because today was much faster than yesterday. Yesterday, he only started moving the Leviathan after entering the digestion state.

He started moving seaweed today right after Leviathan began eating, and now only one-fifth remains. Once his strength recovers, he'll be able to move the rest of the seaweed quickly.

Moreover, the strategy for moving seaweed was changed today, and the oxygen in the stomach wall space is still sufficient, so there is no need to rush.

After resting, Zhou Wen prepared to move the remaining seaweed, but an accident occurred.

Zhou Wengang reached into the seaweed pile, about to pick it up, when something in the seaweed pile scratched his arm, followed by a sharp pain.

Zhou Wen jolted and immediately pulled his hand back. The light shone on his arm, revealing a nearly 5-centimeter-long scarlet wound. Blood seeped from the wound, flowing from his forearm to his palm, with drops of blood dripping from his little finger.

"Holy crap, what is that?!" Zhou Wen clutched his wound and quickly moved away from the seaweed pile.

The next moment, the seaweed pile shook a few times, and a creature sprang out from it.

Zhou Wen was terrified and took a few steps back, fearing that some unknown creature might be hiding in the seaweed pile and attack him.

This place was originally an unknown world. The phallus Leviathan that coexisted with him was 30 meters long when it was born, which shows that this world is extraordinary. The other creatures living in this ocean world must also be extraordinary.

Zhou Wen dared not approach rashly. He took off his headlamp and began to crank it by hand to ensure that it would continue to provide illumination in order to avoid being ambushed by an unknown creature in the dark.

"Pat-pat~ pat-pat~." In the darkness, the sound of the carapace slapping against the flesh echoed through the stomach cavity.

After the unknown creature jumped out of the seaweed pile, it seemed to keep bouncing in place without approaching Zhou Wen.

The headlamp's beam only reached a distance of two or three meters, which was not enough to illuminate the unknown creature. Zhou Wen waited for a while longer before deciding to muster his courage and approach to take a look.

It wasn't that he was deliberately taking risks, but his injured arm was bleeding profusely and needed to be bandaged and the bleeding stopped as soon as possible.

But with the threat of the unknown creature nearby, he dared not spare any energy to bandage his wounds.

Zhou Wen held his breath and slowly moved closer, the beam of his headlamp sweeping across the area two or three meters in front of him. Finally, Zhou Wen saw the appearance of the unknown creature.

"This is... a shrimp?"
