The sea water was cold, and Zhao Lin was wrapped in the water circulation, and he could still feel a trace of coolness.

When they descended to more than ten zhang, the light was already very weak, and ordinary monks could only rely on their divine sense to detect the surroundings.

The divine consciousness is greatly attenuated in the water, and it is generally discounted in half, and if it encounters an obstacle, the detection distance is shorter.

Fortunately, Zhao Lin was able to release ultrasonic waves, which not only did not weaken in the water, but spread faster and farther, reaching a distance of three hundred zhang.

Zhao Lin dared to perform this task, and the Dacheng-level water resistance technique was still secondary, mainly relying on echolocation ability.

This is a huge advantage over other monks.

According to the feedback of the ultrasound, Zhao Lin quickly formed a picture of the bottom of the sea in his mind.

Densely swaying aquatic plants, schools of swimming fish, towering reefs, and gravel all over the seabed......

"According to the information on the map, there are about a dozen places where mussels gather. But don't worry for the time being, most of these clam demons are usually hidden in the sand and are difficult to find. ”

"The best time to collect orbs is in the evening and early morning, when they are at their most active. Right now...... Find a place to lurk first. ”

Zhao Lin thought for a while, made up his mind, and swam straight towards a reef cluster more than ten miles away.

Yongdeng Dark Sand is rich in aura, although the spiritual veins are sealed, the aura that escapes still attracts many sea creatures, especially the clam demons and shell demons who like to swallow aura.

When Zhao Lin was swimming, he encountered all kinds of strange-looking underwater creatures from time to time, including monsters and ordinary fish and shrimp.

Without waiting for Zhao Lin to get closer, these creatures avoided from afar.

Just as he was approaching the reef, a large school of fish swam across the road.

The fish swam fast, big and small, as if something was chasing after them.

Zhao Lin was slightly surprised, and hurriedly swam sideways, put away the water control technique, and hid behind a big rock.

As soon as the water control technique was collected, the sea water immediately poured in down his neck, and the pressure on his body increased suddenly.

No matter how powerful the water is, ordinary people can only dive to a depth of ten zhang at most.

As the depth increases, so does the water pressure, which the average person simply cannot bear.

With a depth of more than thirty zhang, even Qi Refining Realm cultivators could only rely on spells to resist it.

Zhao Lin is a martial arts master, not to mention the strength of his body, he restricts his breath and stabilizes his motionlessness.

After a while, a large black figure passed in front of him.

The black shadow was more than three feet long, with a round body, and as it lunged forward, it opened its mouth wide and devoured the fish that fell behind.

"It turned out to be a fish demon."

Zhao Lin breathed a sigh of relief, but remained unmoved.

Such a large fish is not uncommon in the sea, and Zhao Lin judged that it was a fish demon because it sensed mana fluctuations.

The Yongdeng Dark Sand is relatively shallow, and there are no particularly ferocious demon beasts, and the biggest threat to the monks is the fish demon.

The fish demon has a certain amount of wisdom and knows that monks are not easy to mess with, so they generally do not take the initiative to attack.

However, Zhao Lin felt that it was better to be careful, he didn't want to waste his spiritual power on fighting the fish demon.

It wasn't until the figure of the fish demon disappeared into the distance that Zhao Lin regained his water control technique and swam in the original direction.

"This is it."

Soon, Zhao Lin came to a reef thicket.

The underwater reefs are of different shapes, and the surface is covered with cyan algae, stacked one by one, like undulating rockeries.

Zhao Lin carefully observed for a while, making sure that there were no monks or demon beasts inside, and then slowly swam in.

Find a reef with a hole in the middle, put away the water resistance, embed your body in it, and the whole person becomes one with the reef.

It was inconvenient to replenish spiritual power in the water, so Zhao Lin planned to act when the clam demon was most active. Stay here during the day and hide from the strife outside.

An hour passed, Zhao Lin didn't make any movement, and a few small fish passed by him, but he didn't even notice it.

Two hours, three hours......

In the afternoon, the sand next to the reef suddenly churned.

Rustle rustle......

The sand and gravel shook like boiling water.

Zhao Lin looked over in surprise, only to see that it was completely dark, and he couldn't see anything clearly.

Ultrasound was released, and an octagonal object with a flattened, flat body was slowly emerging from the bottom of the sea.

"It's an octagonal mussel!"

Zhao Lin didn't expect that there was a clam demon in the place where he was hiding, but it kept gathering its breath and was buried deep under the sand, so it didn't find it.

"What does it want to do?"

Zhao Lin observed silently and did not take immediate action.

The formation of the spirit bead is similar to that of the pearl, the difference is that the clam demon absorbs the aura, so the spirit bead contains a large amount of aura.

To determine whether a clam demon is pregnant with a spirit bead, it is difficult to distinguish from the appearance alone, and there is only one way to open it.

Like most clam demons, the octagonal mussel's defense ability is very strong, not only is it born with its own water defense spell, but the clam shell itself is extremely hard, and ordinary magic weapons can't break it at all.

The octagonal mussel has the ability to breathe, and the breath is poisonous, and if it is directly touched, it is very difficult to subdue an octagonal mussel.

Zhao Lin didn't know if this octagonal mussel contained spirit beads, in case he tried his best, but there was only mussel meat in the mussel shell, it would be worth the loss.

After fluttering for a while, the true face of the octagonal mussel was completely revealed, the length was nearly two zhang, and the thickest part was more than one person high.

After a while, the octagonal mussel opened its shell, revealing a gap, and then it stood still, as if observing the outside world.

Zhao Lin's eyes narrowed slightly, and when he looked sideways, he faintly saw a faint light shooting out from the inside of the mussel shell.

"Sure enough, there are spirit beads!"

Zhao Lin was overjoyed, and unconsciously began to pinch the magic trick in his hand, but his mood quickly calmed down, and now was not the time to do it.

Time passed slowly, and the octagonal mussel felt safe, and the shell of the mussel became bigger and bigger.

From Zhao Lin's point of view, although he couldn't see the spirit bead inside, from the light that emanated, the spirit bead was definitely not small.

The octagonal mussel didn't know that danger was around him, and the mussel shell closed one by one and began to slowly swallow the aura.

With the opening and closing of the mussel shell, the brilliance flows, flickering and flickering.

Seeing that the time had come, Zhao Lin reached into the lock bag with one hand, grabbed out the sponge sand, and pinched the spell with the other hand, and the water-shaped circulation quickly formed.

"Water Resistance!"

The Dacheng-level spell only needed one-eighth of the time, and Zhao Lin dodged in front of the octagonal clam like a swordfish.

Before it can react, wave its arms and throw out a handful of sponge sand!

Brush!

Hundreds of grains of sponge sand flew between the two mussel shells.

The sponge sand frantically absorbs water, and the flesh of the star anise mussel instantly collapses, shrinking to less than half of its original size, and its color changes from bright red to miserable white.

At the same time, Zhao Lin saw the situation inside the mussel shell.

I saw a light blue spirit bead shining, the size of an egg!
