Chapter 93 Ocean Currents
Muscle soreness after anaerobic generation will slow down the overall movement effect of insect sharks.

The bug sharks were always stopping and going, and they were wearing Zhang Fan's patience.

On this road, sea spiders and lantern fish appeared again.

Sea spiders don't need to worry about it. The place here is relatively spacious and will not pose the slightest threat to the insect sharks. On the contrary, when they attack the insect sharks, they will be killed instead.

The trouble is those lantern fishes. Sure enough, as Ling said, the lantern fishes are extremely ferocious, and the spirit of going forward is admirable.

Those big teeth look scary, but it's hard to do harm to insect sharks.

At the beginning of the attack, Zhang Fan broke out in a cold sweat.

The teeth of the lanternfish are more like sieves. They often feed on small creatures. They will attack the enemy when their territory is violated, and usually scare the enemy away with their terrifying appearance.

However, I didn't expect that a insect shark who is also not afraid of life and death will come this time. This idea is very difficult.

After seeing the slight damage caused by the lantern fish to the insect shark, Zhang Fan's heart of mischief broke out.

He controls the main body of insect sharks not to bite lanterns, and only picks their lanterns to bite.

Every time the lanterns were bitten off, the lantern fishes were in so much pain that Zhang Fan would let the insect sharks devour the lantern fishes.

After decomposing the genes in its body, it was found that there was nothing worthy of praise.

After cleaning up the surrounding lanternfish, the bug sharks moved on.

The current in front of them became more and more turbulent, and the bodies of the insect sharks wandering in the sea became wobbly.

"There seems to be an ocean current ahead." Feeling the flow of sea water, Zhang Fan thought thoughtfully.

"Go and have a look." The insect sharks swung their bodies and continued to move forward.

The more turbulent the water flow, the higher the concentration of oxygen in the seawater, and the insect sharks gradually regained their spirits.

This is easy to explain, just like a fish tank, if there is no oxygen rod, the oxygen in the water will gradually decrease, and finally all the fish in the tank will die.

And with the oxygen rod, the water flow is formed, and the oxygen will penetrate into the water, and the turbulent water flow just brings the oxygen in.

The flow of seawater was getting faster and faster, Zhang Fan couldn't control the bodies of the insect sharks, so he simply let go and let nature solve the problem.

After touching the control of the insect sharks, the group of insect sharks were pulled over by the current at once.

There are dangers everywhere in this underwater cave.

For example, Zhang Fan didn't control the rhythm well, and a bug shark accidentally floated above the current, and was split in half by a stone pillar in front.

And the stone pillar was broken by the violent impact, and the sharp edges stabbed another insect shark.

This is not over yet, the stone pillar will be carried forward by the current, and the insect sharks are very difficult to avoid its attack.

Just such a small stone pillar caused the death of four insect sharks.

Not counting the big rocks driven by the water, these rocks are even more threatening, they will cover the entire passage, and once they are caught up, they will be smashed to pieces.

The bones scattered here and there in the current are good evidence.

The insect sharks tried their best to escape the dangers, and finally saw the light again. The water flow there could no longer be described as water flow, but a torrent.

Under the action of strong suction, the insect sharks could no longer control their bodies, and rushed out of the hole under the action of the spiral.

It was very painful to be hit by the crackling stones behind me.

After leaving the cave, Zhang Fan only knew at this time that this place originally belonged to the ocean current zone.

Ocean current, also known as ocean current, refers to the large-scale flow of sea water along a certain path in addition to the tidal movement caused by tidal force in the ocean.

This world has no moon, so the movement of gravitational tides can be ruled out.

The main driving force of the movement of ocean currents is wind, and it can also be the inhomogeneity of seawater density distribution caused by thermal-salinity effect.

To put it plainly, the ocean currents caused by temperature changes have a certain periodicity.

Ocean currents are the main regulators of the thermal environment on the surface of the planet. They can be divided into warm currents and cold currents. If the water temperature of the ocean currents is higher than that reaching the sea area, it is called a warm current; if the water temperature of the ocean currents is lower than that of the water reaching the sea area, it is called a cold current.

Feeling the temperature around him, Zhang Fan guessed that it must be a cold snap.

So speaking of it, this ocean current should be able to take Zhang Fan towards the southern hemisphere.

"I'm really looking forward to it, I can finally visit the southern hemisphere." Zhang Fan thought excitedly.

However, ocean current movement is not absolutely safe, and many creatures in the ocean rely on ocean currents for migration.

At best, these insect sharks are just a drop of water in the pool, not a threat to the surrounding environment.

The biggest threat in this current is the large tuna.

From their name, this kind of tuna can be seen to be relatively hard. There is a short and sharp horn on the top of the head, which is a bit like a swordfish. Zhang Fan speculates that this may be the ancestor of the swordfish.

The body of these tunas is golden yellow, the scales on the outside are as hard as steel plates, and they are about the size of insect sharks.

Tuna are invincible in ocean currents, they are like scavengers cleaning up all creatures in front of them.

Even giant star molluscs strayed into the ocean currents will be twisted to pieces by them.

Zhang Fan's luck was relatively good, the insect sharks happened to follow behind the tuna, and there was a big guy ahead to open the way, which could save a lot of energy.

There are also some small crustaceans in the ocean current, and only these small creatures can escape the tuna's charge.

These fish that slipped through the net can just replenish the physical strength of the insect sharks.

On the periphery of the ocean currents, there are some creatures that rely exclusively on ocean currents for predation. Zhang Fan calls them jet beetles.

This jet beetle looks like a white ball when it is outside the ocean current. Once prey enters its field of vision, it will quickly squeeze the seawater in its body, which is very similar to a cuttlefish spitting ink. .

After spraying the water, the body of the jet beetle becomes very slender, and then enters the ocean current to hunt.

Jet kiss bugs have a super fast moving speed, and their attitude is decisive. If they fail to succeed in one blow, they will leave the ocean current quickly without staying for a moment.

They know that once they enter the ocean current and cannot get out, they will die in it forever.

Zhang Fan was also attacked by this jet kissing insect, and he didn't give the insect shark time to react at all.

As long as you are attacked by these air kissing insects, you will be immobilized by the blood clotting factor in the kissing insects.

Then after being taken out, it will be devoured by other jet kissing bugs.

Along the way, Zhang Fan was attacked by jet kissing bugs big and small, and several insect sharks Zhang Fan watched helplessly as the kissing bugs dismembered them.
