The young frogman inherited the strong physique and strength of the ancestor frog, and the combat power is obviously stronger than that of the fishman, and it will not be weaker than an adult man in terms of physique and strength.

Within a few minutes, the fishmen were defeated, chased and killed by the frogmen, and the corpses were carried back to the swamp as trophies.

It wasn't until the frogman disappeared that Lin Xiao left with the Naga with a solemn face.

It can be seen from the battle just now that the individual strength of the frogman is not as good as that of the Naga, but it is far stronger than the fish man, and it is weaker than the Naga is also limited.

The mission requires the extermination of five frogman tribes ranging in number between 5,000 and 8,000, adding up to at least 25,000 and 40,000 frogmen.

Fortunately, these five tribal groups are scattered, and the level of threat of a single is smaller than that of the 20,000 fish-man tribes, which is the main reason why it is rated between eighty points like the previous task.

However, for Lin Xiao, it is much more difficult to exterminate the frogman than to exterminate the fishman, and the fishman can also take advantage of the relationship of the same clan, and the frogman does not have that advantage, so he must do it with a real gun.

Back at the gathering point, after a few days, with the efforts of the industrious fishmen, a few simple tents have been built at the gathering point, and a large amount of wood and stones have been moved and piled up into a mountain.

Under the command of a few Naga overseers, a large number of fishmen used these materials to build fish-man huts along the beach.

Lin Xiao was a person who couldn't sit still, he stayed at the gathering point for a day, and went out with a group of Naga, this time not to the seaside or the swamp, but to go upstream along the north bank of the Heishui River, and by the way, to see how deep the Heishui swamp was deep into the mainland.

This time, he took fifty nagas and two hundred fishmen and walked directly along the river.

There is no modern industry, this river has maintained the most primitive ecology, the river is full of calamus, cattails, shallots, reeds and other plants, some grow in the water, some grow on the river bank, you have to go out of a road.

There are many floating plants near the shore of the river, such as large stalks, water chestnuts, etc., floating on the surface of the water.

There are some submerged plants at the bottom of the water, such as water lilies, water pen boys, anemones and so on.

Many insects and small fish swim around in the aquatic plants, nibbling on aquatic plants.

The fish-men who traveled ahead swam past these aquatic plants, occasionally breaking off a piece of green leaf and stuffing it into their mouths, or taking out a snail from the bottom of the water and biting it open, digging out the meat and swallowing it.

Fish-people are omnivores, basically whether it is grass roots and green leaves, insects, fish, etc., even rotting corpses eat, very easy to feed.

There are many fat freshwater fish in the river, and occasionally you can see huge black shadows passing by, Lin Xiao's eyesight is very good, and he can clearly see that they are huge carnivorous fish, or crocodiles and pythons, but their team is huge, and these predators dare not come.

It took me more than half a day to walk about thirty or forty kilometers up the river and came to a large lake.

This is a large area of deep water near the river of the Blackwater Marsh, and there are no swamp islands, and it is connected to the Blackwater River, so it looks like a large lake that looks white at a glance.

At this point, Lin Xiao asked the team to stop and watch for a while, and ordered everyone to go ashore.

Because he just observed the deep river in front of him, he faintly felt a faint threat in the river, and there must be a big guy hidden in such a big lake.

The shore is more difficult to walk than in the water, there are too many weeds, and from time to time you will encounter poisonous snakes or other poisonous insects hidden in the grass, and on the way around this more than ten kilometers of big lake, there are more than a dozen fishmen who walked in front of them died in the mouth of the snake and the poisonous insects.

Fortunately, it took almost four days to cross this large lake and continue to go into the water and walk by the river, and finally came to the end of the swamp after walking for almost 200 kilometers.

Lingering in the neighborhood for a long time and returning directly the way he came, he didn't go around the swamp or go straight through the swamp, it was too dangerous.

Four days later, when I came to the mouth of the Great Lake again, I saw a large group of swamp people fishing on the shore of the Great Lake from a distance, that is, frogmen, who had not been seen before when they came, and estimated that their tribe was in a swamp not far away.

Lin Xiao thought about it for a while, waved his hand and slowly leaned over from behind with his subordinates, he was ready to try the quality of these frogmen.

But when he was about to get closer, he suddenly glanced into the lake and saw a huge shadow slowly approaching the frogman fishing, and he immediately waved his hand to signal his subordinates to retreat.

More than ten seconds later, with the sound of a huge splash exploding, a huge black shadow rushed out of the lake, biting and dragging the two frogmen into the lake at the same time.

In the electric light, Lin Xiao saw the appearance of the huge black shadow clearly, it turned out to be a huge crocodile, or emperor crocodile, also called a fierce crocodile.

It looks the same as a crocodile, but its size is even larger, and just now I saw that its size was more than fourteen or fifteen meters, and its body was covered with bumps, which was extremely ugly.

This kind of ferocious crocodile is extremely brutal, fierce, and very powerful, with a huge mouth that can bite and drag an elephant into the water, can swallow a horse in one bite, and its combat effectiveness in the water is very strong, Lin Xiao estimates that if their team encounters, it will not be possible to get a bunch of cannon fodder without dying.

This is still the case of calculating the salted fish spike outbreak, and without this outbreak, the casualties would have been greater.

This guy's crocodile skin is thicker and tougher than ordinary crocodiles, and his physique is taller and more resistant to roughness, and he can withstand high bursts without dying.

Then the ferocious crocodile killed two more frogs before leaving, and the other frogmen did not dare to go into the water to save their companions.

At the same time, Lin Xiao quietly touched it again, and when the frogman was frightened, he suddenly burst out of the water, he was the first to rush out and poke a frogman into the water, and smashed another frogman on the side with a backhand shot, and turned his thick tail on the spot to smash another frogman with a weapon, and a set of actions to solve the three frogmen cleanly.

Although the movements of other Naga are not as amazing as his, they are not bad, after all, the Naga who can be brought by him are at least level two, more than a dozen level three, and their strength is much stronger than that of frogmen.

By the time the fish-men rushed up, the battle was over, just waiting for the end.

The frogman corpse ignored it, and they quickly left.

For Lin Xiao, the frogman race was useless to him in terms of talent and skills, and had no value for refining.

A few days later, when he returned to the gathering point, the tribe had taken shape, and Lin Xiao sent a small team of Naga garfish people back to the original tribe, so that the tribe was ready to relocate, and he was ready to make a move on the frogmen.
