This lake is very large, and Song Jian knows that the monster hidden in it must be more than the deep-water crocodile beast in front of him, and there may be even more fierce existence.

But the treasure that can be reborn with a severed limb, Song Jian believes must be under this lake;

After hesitating for a moment, Song Jian slowly sank into the water, opened his eyes and observed carefully, Song Jian was now able to be underwater for only fifteen minutes, and after more than fifteen minutes, he would begin to lose blood, and it would fall faster and faster, at most ten seconds, all the qi and blood values would be lost;

The lake water is clear, and Song Jian found a lot of monsters underwater, there are dozens or hundreds of such monsters similar to deep-water crocodiles, and there are many other monsters that have no limbs like fish;

Moreover, there are many water element monsters in this lake, which are similar to those water elements that Song Jian found in Jinyang Lake before, and their value is not enough to be much higher in size and strength;

Song Jian came here not to kill monsters and upgrade, but to explore treasures that can be reborn with broken limbs, so he was also careful to avoid along the way, every once in a while, when the breath-holding time was almost up, Song Jian would swim to the surface of the lake, rest for a while, and then continue to dive to the bottom of the lake;

For more than an hour, Song Jian only searched less than one-tenth of the area, which was already tired enough, but unless he saw a large number of monsters at the bottom of the lake, he didn't find anything else.

"Do you really want to cut off another monster's limb and follow it to see how it is reborn?" Song Jian's brows furrowed;

At this moment, there was a sudden fluctuation of the lake in front of him, Song Jian looked forward, and a large area of mud and sand was turned up from the bottom of the lake, and vaguely, it seemed that two monsters were fighting each other in the water;

Almost all the monsters were attracted by their fight and surrounded them, but it didn't take long for them to flee in all directions like frightened birds.

After a while, all the monsters were far away from the two monsters who were fighting;

Song Jian carefully examined the attributes of these two monsters, both of them were monsters with first-order combat power, one of them was a level 35 deep-water crocodile beast, and the other was a level 38-level deep-water lake eel;

The two monsters fought upside down, Song Jian slowly approached, and soon, the two monsters were a little exhausted, and the deep-water lake eel flicked its tail, and suddenly released a huge electric current, flying towards the deep-water crocodile beast, like a heavy hammer, directly catapulting him out;

Rumble!

The deep-water crocodile beast was directly knocked five or six meters away, as if it had hit an invisible transparent wall, and made a dull sound under the water;

In the void, there seemed to be a crack in the lake, which flashed in the lake, but this flash of light made Song Jian capture it, and his eyes suddenly lit up.

"Could it be that there is a similar secret realm at the bottom of this lake?" Song Jian secretly said in his heart, temporarily suppressing the eagerness to probe in his heart, waiting for the battle between the two monsters to end;

It didn't take long for the deep-water crocodile beast to be defeated by the lake eel, and slowly retreated, although the lake eel won, but it itself was also injured a lot, staring at the crocodile beast slowly retreating, and did not chase after it;

In a moment, the deep-water crocodile was gone, and the deep-water lake eel was lying in place, curling and curling into a ball.

Song Jian found that in the center of the deep-water lake eel's body, there seemed to be a glittering stone, which was the size of a human head, and was almost buried by the sand at the bottom of the lake, but after a fight, the stone was completely exposed;

The stone exudes a rich pale blue light, and there are small electric arcs on the surface that are constantly beating, and the deep-water eels lick the surface of the stone from time to time, looking very enjoyable;

At this moment, four sharp long swords suddenly rushed over from the water like arrows, and before it could reflect, the four long swords continued to slash at its body, and the deep-water lake eel, which was already seriously injured, was directly cut into several pieces after a while, and even Song Jian didn't see what he looked like until he died;

Song Jian swam over, first picked up the two materials dropped by the deep-water lake eel, and then his eyes fell on the pale blue stone;

Because he had been fighting with the deep-water crocodile beast for a long time before, this was a deep-water lake eel that had been seriously injured, otherwise, Song Jian would not have been able to kill it so easily, so the quality of the items it dropped was not very good, Song Jian just glanced at it and threw it into the package bar.

This light blue stone is a power stone, which can allow pets to evolve, and there is a certain chance to obtain electric attack skills;

It's just that for the deep-water lake eel, the energy contained in this power stone is too abundant, and if it is swallowed directly, I am afraid that its body will burst, so it is just slowly absorbed around it;

Because of this, this energy stone ended up being cheaper than Song Jian;

Glancing at the stone man and the black dragon in the pet space, Song Jian suddenly hesitated, who is this energy stone better for?

At this time, the little stone man was falling into a deep sleep because it had devoured the core of the Earth Elemental Lord, and at this time, it was obvious that its body had more than doubled in size, and it was already about the same height as an adult man.

And the black dragon had already recovered from his injuries, and when he had nothing to do, he also fell asleep on his stomach, as if he felt Song Jian checking the pet space, the black dragon opened his golden vertical pupils violently, glanced in the direction where Song Jian was, and let out a dragon groan, as if he was saying hello to Song Jian;

Song Jian smiled slightly, the little stone man is just an ordinary monster, and he doesn't even have first-order combat power until now, if he wants to digest and absorb this electric attribute energy stone, he doesn't know how long it will take, it is better to give it to the black dragon, after all, with the grade of the black dragon, if he wants to absorb this electric attribute energy stone, I am afraid that he does not need to work as hard as the deep water lake eel;

Song Jian held the energy stone in his hand and directly chose "use" to the black dragon, and suddenly, in the pet space, a light blue energy stone with electric light appeared in front of the black dragon.

Seeing this power stone, the black dragon first curiously pulled it twice with his paws, then his eyes lit up and he swallowed it into his stomach in one gulp;

Thorn~

Streams of lightning came out of the gaps in the black dragon's scales, constantly flowing on the surface of its body, and there were bursts of dragon groans in Song Jian's ears, which didn't sound like pain, but had a refreshing taste;

"It's like doing electrotherapy...... Song Jian was a little speechless as he watched the black dragon rolling in the pet space, and a string of electric currents appeared from the surface of his body from time to time, but it was obvious that the strength of the black dragon was rapidly improving, and even the level began to break through, jumping directly from level thirty to level thirty-two, and it continued to improve;

"It seems that it won't be over for a while, so let's wait until it completely digests the energy stone." Song Jian shook his head, directly closed the pet space, and walked towards the spatial crack that flashed before;
