The underwater breathing agent works by covering the mouth and nose with a thin layer of light, separating the oxygen from the water and keeping the lake water out when breathing. The four of them walked into the depths of the lake step by step, although they have the ability to breathe underwater, but the resistance brought by the lake still exists, and the deeper they go, the greater the resistance. Of course, with the current physical fitness of the four people, these pressures are not a problem at all.

Xiao Yu's ability to resist the wind in the water was restricted to a certain extent, but the impact was not great, and he could still fly in the air, while Han Kexin directly transformed into a throne with blood energy, shuttling back and forth in the water, Jiang Xiaowen and Yun Yun followed closely behind Han Kexin, and the four of them moved towards the center of the lake.

The water of the lake is very clear and clean, there are a large number of small fish and shrimp swimming in the water, the bottom of the lake is covered with a layer of unknown water plants, most of them are full of spikes, the color is very bright, it may be highly poisonous, many of the corpses of the sea tribes who were killed by the arrow tower in the attack sank, distributed all over the bottom of the lake, and the rudimentary weapons and armor were scattered everywhere.

Xiao Yu looked around and then gestured to Jiang Xiaowen.

Jiang Xiaowen immediately understood, and the lilac soul chain immediately connected the four people together. One of the functions of the soul chain is to communicate with the heart, even if you don't need to open your mouth, you can communicate unconsciously on the spiritual level.

Han Kexin conveyed a spiritual message to the other three: "The corpses of the fishmen have all been gnawed, there must be dangerous carnivorous monsters nearby, I think there should be no safety in this lake as imagined." ”

Xiao Yu also spoke: "Yes, don't take it lightly, we are not very good at water warfare, if we encounter sea clan warriors in the water, it will be a big trouble." ”

Jiang Xiaowen felt the sound of turbulent water, and immediately shouted, "Listen, everyone, there is a sound." Something is approaching ahead! ”

The four of them immediately noticed a group of spindle-shaped silver strange fish rushing towards them like lightning, and there were six or seven hundred of them, shooting towards them like ten thousand arrows in unison. These silver strange fish are shaped like a shuttle, three meters long, the widest part is no more than the length of a palm, the mouth is sharp and long, like a huge steel needle shuttling in the water, the speed is unimaginably fast, it is like a meteor, the water automatically rotates around its shape in the process of swimming, and these strange fish are like a long and sharp spiral water cone in the process of swimming.

When Jiang Xiaowen found out, the fish had already rushed to the front, blocking all angles up and down, left and right, Xiao Yu rushed up and pulled her from the side, hundreds of silver water cones roared past the four people, one of which was close to Xiao Yu's right cheek, leaving a deep wound, a few traces of blood seeped out of the wound, Jiang Xiaowen's shoulder was also cut, Yun Yun and Han Kexin were also injured in several places.

Han Kexin was a little surprised, and said to the others through the soul chain: "Their speed is really fast, and their attack power is also very strong. ”

Xiao Yu said with his thoughts: "This is a surprise fish, and there are a lot of reproduction in both freshwater and seawater. Their individual strength is not very good, but they always like to appear in groups, and their strong penetration is enough to penetrate the third-level physical defense, even if it is a third- or fourth-order aquatic monster encountering thousands of assault fish, they will only be pierced by ten thousand arrows. ”

After the assault fish passed through the four people, it rushed out of a distance of several hundred meters in the blink of an eye.

Jiang Xiaowen glanced back at Xiao Yu and asked with concern, "Are you okay?" ”

Xiao Yu's face was cut out when it was grazed by the assault fish, and in just a few seconds, the wound solidified and stopped bleeding, and at the same time there were some signs of dryness, not like the wound on the flesh and blood but more like a crack on the dry mud ground, and the tiny sand emerged in a thread, slowly filling the wound. Probably due to the influence of the water environment, the speed of wound recovery is very slow, and it takes five or six seconds for a shallow wound to fully recover.

Xiao Yu is not a demigod in the end, although he has the immortal nature of an immortal body, he is still too far from the real immortality, but it is enough to make Han Kexin and the others envious. At this moment, the school of assault fish that swam far away suddenly turned around and rushed again, leaving a long silver-white trajectory in the water, like hundreds of bullets shooting towards the four people.

"Blood Demon King!"

Han Kexin's power burst out, the bewitching blood-red mark on his chest shone brightly, and countless bright red blood power was released from his body, causing the surrounding lake to surge up like a boil. The huge blood power enveloped Han Kexin's body and rose into the sky, gradually forming a blood demon king with a half-body skeleton image. The bones are very thick, the roots of the ribs are visible, as if they are substance, the color of the bones is blood red, the two eyes in the skull emit a terrifying fierce light, and the entire Blood Demon King is shrouded in a ball of blood power like flames.

Han Kexin manipulated the throne and quickly flew over to block the three of them and the fish, and the Blood Demon King raised his right bone arm, which seemed to be very slow, but it was actually extremely fast, and the bone fist blasted straight forward. The bottom of the entire lake boiled in an instant, the blood power pushed the lake, and the bright red power mixed with the water waves frantically surged towards the assault fish, and a group of assault fish in the front row were involved in the blood power and directly exploded to death.

The assault fish hit the Blood Demon King one by one, and the Blood Demon King's body showed a large fluctuation, its eyes were fierce and generous, and under Han Kexin's manipulation, its left arm swept out, and more than a dozen assault fish were slapped into meat paste. However, there are too many assault fish, and all of them are not afraid of death and rush up, it is inevitable that some fish will be caught in the net, and under the attack intensity of up to three levels, the Blood Demon King is suffering several impacts, and finally an assault fish breaks through the body of the Blood Demon King and hits Han Kexin's chest like lightning, coming out of the body, piercing out from the back, and a large number of blood beads flying out backwards.

Han Kexin spurted out a mouthful of blood, countless blood forces gathered from all around, and quickly condensed on the wound, the fist-sized wound healed in an instant, and the Blood Demon King suddenly dimmed a lot.

Jiang Xiaowen's wings flapped, countless dust containing spiritual power covered the assault fish, a large number of fish fell down, Yun Yun pulled out the longbow and shot five arrows in a row, each powerful arrow pierced at least three fish.

"Teacher Han, it doesn't matter."

Jiang Xiaowen rushed to Han Kexin and pulled out the wind and sand war spear from the ring, this spear didn't seem to be substantial, it was made of wind and sand as a whole, and it didn't look like an ordinary product. Jiang Xiaowen waved the spear lightly, and a not weak wind and sand force swept out, and the power of the blue weapon was ten times stronger than the green weapon!

A bright red bone arm stretched out, and the assault fish hit it and were bounced away, blocking an attack from the side for Jiang Xiaowen.

Han Kexin sat on the throne and went up a few meters to help Jiang Xiaowen, "I'm fine, you be careful yourself." ”

Xiao Yu had already distinguished the trajectory and speed of the assault fish in the few seconds just now, and when the assault fish swimming at high speed slowed down and was about to turn around, suddenly a cold force instantly covered this area of water, and these assault fish were frozen in the thick ice before they could react.

Yun Yun's fingers pulled the bowstring, and when she was about to shoot an arrow, a large area of water in front of her was instantly frozen, and almost all the assault fish were frozen in it, such a picture completely shocked her. How much mental power does it take to freeze a body of water in an instant.

Xiao Yu's skill "Red Lotus Hell" is cast through the eye, which can be directly applied to the target, so when he used the Red Lotus Hell against the Assault Fish, the lake along the way was not affected in any way, and the area where the Assault Fish was located was instantly frozen under the power of the Red Lotus Inferno. Xiao Yu didn't release too much of the power of the Red Lotus Inferno, but only released a trace of the power of the Red Lotus Inferno, and what froze the assault fish was not the crimson Red Lotus Cold Ice, it was just an ordinary ice cube.

Xiao Yu is really becoming more and more proficient in the use of the power of the Red Lotus Hell Fire, and with the advantage of the environment, in fact, the blow just now did not consume much mental power.

Yun Yun let go of the bowstring, and a fiery arrow shot out, and the fire element evaporated a large number of bubbles in the water, leaving a long trajectory in the book, and finally landed on the huge ice block, and with a loud bang, the entire ice block split apart and shattered, and the assault fish frozen in the ice was also destroyed with the ice shattering.

Strictly speaking, the Assault Fish are just first-order monsters, and although they are very dangerous when they are in groups, their individual strength is relatively weak, and their mental strength is not strong.

Therefore, the items dropped by the Assault Fish are basically white and gray, and the total number of items dropped by hundreds of Assault Fish is only a dozen.

Xiao Yu asked Jiang Xiaowen to untie all the loot collection one by one to check, most of the loot were some white-grade equipment, which was not bad for ordinary people, but Xiao Yu and the others really couldn't look down on it.

When Xiao Yu unlocked the last ball of light, he didn't expect that after this ball of light was unraveled, a simple stone appeared in his hand.

"Level 1 Secret Realm Opening Stone, Abandoned Underwater Farm", used to open rare Level 1 Basic Secret Realm, rare underwater farm.

Xiao Yu didn't expect that killing a batch of assault fish would actually drop a secret realm stone, which was really a big explosion of character. The first-level secret realm is the lowest level of the secret realm, and it is also the basic secret realm. Any city has three basic secret realms: plantation, breeding farm, and excavation field, and the breeding farm of this underwater farm is a rare basic secret realm.

"The trouble has been lifted, the time for the water-based respiratory medicine is limited, and the task is urgent, but we need to speed up."

Xiao Yu distributed the early warning puppets one by one at the bottom of the lake, and the early warning puppets automatically woke up when they found that the monsters with strength exceeding the second order were set up, and Xiao Yu planted a batch of goblin mines in the coastal area, which could give them a blow when the sea clan landed.
