On the top of the hillside is a small lake, in the middle of the lake there is a small island of a few square meters, on the island are placed three treasure chests, each treasure chest exudes colorful light, energy crystals must be in these three treasure chests!

Yan Fei's eyes lit up first, and then his gaze dimmed again, Qin Yuxin's curse had not been lifted, and the current priority was to find the Moon Spring, as for the treasure chest on the island, put it aside first.

Yan Fei glanced and found that the water in the lake was flowing down from another mountain peak next to him, so Yan Fei carried Qin Yuxin on his back and walked towards the peak quickly.

"Yan Fei? Where are you going? Treasure chest, there is a treasure chest on that island! And it's a colorful treasure chest, and the energy crystal must be inside! Qin Yuxin said excitedly.

"Leave the energy crystal alone, find the moon spring water first!" Yan Fei said lightly.

After Qin Yuxin heard Yan Fei's words, she suddenly quieted down, lay on Yan Fei's back with a happy face, and said "um" softly, and then stopped talking. It's nice to be guarded by a man!

The water flow was flowing down from the mountain peak, Yan Fei carried Qin Yuxin on his back and climbed up the mountain road with difficulty, and after a while, a natural karst cave appeared in the middle of the mountain, and the source of the water flow was in this karst cave.

Yan Fei's vision was not affected by the darkness, so he did not hesitate to burrow into the cave, and Qin Yuxin, who was lying on Yan Fei's back, said worriedly: "Yan Fei, the cave is so dark, you go slowly." ”

"Don't be afraid, I have the skill of the eye of the mind, and the darkness is the same in my eyes as the day." Yan Fei comforted her.

"Oh, then be careful, I don't know if there will be monsters in here." Qin Yuxin was still not at ease.

"Hehe, it's best to have monsters, at least prove that there is something inside that is worth guarding by monsters!" Yan Fei smiled heartily.

Listening to Yan Fei's laughter, Qin Yuxin's inner uneasiness gradually calmed down, with this man by her side, what are you afraid of?

The cave is very deep, and there are many turns, but the space in the cave is getting bigger and bigger, and in the dark, Qin Yuxin can't see the surrounding situation at all, and can only hear Yan Fei's footsteps and breathing.

Suddenly, a ray of light broke into Qin Yuxin's eyes, and when she subconsciously looked up, Qin Yuxin found that an empty space appeared in front of her, surrounded by strange rocks, and on the fang-like upside-down stone pillars, water droplets continued to drip down, and the water droplets fell to the ground to converge into a stream of water, and then flowed towards the outside of the cave.

And the cave seems to have come to an end, there is no way out in front of the two, there is a stone platform in front of the two, there is a jade bottle placed on the platform, the mouth of the bottle is upward, it is really aimed at a huge stone pillar, there is still half a drop of water drops left on the stone pillar, it seems that this jade bottle is specially placed here, used to catch the water droplets dripping on the stone pillar.

And the light source that illuminates the entire space is this jade bottle, could it be that the jade bottle contains moon spring water? Qin Yuxin began to tremble excitedly.

Yan Fei stretched out his hand and patted Qin Yuxin's thigh, and then pointed in one direction, Qin Yuxin was surprised, and looked at the place where Yan Fei was pointing, suddenly his pupils dilated rapidly, and he was about to exclaim when he opened his mouth wide, after reacting, Qin Yuxin hurriedly covered his mouth, and his heart beat rapidly!

I saw a reptile covered with sharp spikes, lying on a fanged stone pillar at the moment, it seemed to be resting, this monster is five meters long, the body shape is similar to a crocodile, but the whole body is covered with black spikes, especially the upper jaw to the top of the head, the spikes are dense, at a glance, you know that this monster is not easy to mess with!

When Yan Fei's eye of the mind was opened, the information of the monster appeared in his mind:

Mutated Elder Crocodile (Gold boss), level 45. High Defense, High Attack, High Health, Medium to High Speed. (The specific data is not shown, only comprehensive comments) skills: 1. Crush and bite (advanced), physical attack active skills; 2. Crazy Crush (Advanced), Physical Attack Active Group Skill; 3. Sonic Concussion (Intermediate), Magic Attack Active Skill. Talents: Berserk, double in size, decrease in speed, double defense and attack power.

This is a gold-level boss with high offense, high defense, and thick blood! And there is one more talent skill than the average boss! It's hard to deal with!

Yan Fei cautiously carried Qin Yuxin back and walked back, browsing the skills he had while retreating, when Yan Fei saw his spiritual servitude technique (advanced), and then looked at this mutated ancient giant crocodile, a hint actually appeared in his mind, it can be tamed!

Yan Fei was overjoyed, stumbled under his feet and almost fell to the ground in excitement, but fortunately, Yan Fei reacted in time and reached out to support the stone pillar next to him, barely ensuring that the two of them did not fall, but Qin Yuxin on his back subconsciously exclaimed.

Worst! Yan Fei secretly screamed that it was not good, raised his head and looked at the mutated ancient giant crocodile, and suddenly showed a wry smile.

At this time, the mutated ancient giant crocodile had already opened its eyes, and just lay on the boulder pillar, staring at Yan Fei and Qin Yuxin, Yan Fei only felt a burst of hair in his heart.

Yan Fei stopped the movement of his feet, Qin Yuxin on his back also covered his mouth, and the two of them just looked at each other with the mutated ancient giant crocodile, and after one second, two seconds and five seconds, the mutated ancient giant crocodile suddenly and quickly climbed down from the stone pillar, shaking its limbs, and running towards the two of them with a flick of its tail!

"Ahh Qin Yuxin on his back let out a scream, Yan Fei woke up suddenly, turned around, and fled outside the cave with Qin Yuxin on his back.

Yan Fei was running fast with Qin Yuxin on his back, but the mutant ancient giant crocodile chasing behind him was even faster! In just a dozen seconds, the distance between the two is less than five meters! Yan Fei could even clearly hear the breathing of the giant crocodile behind him!

What to do? Yan Fei was carrying Qin Yuxin on his back, and he would definitely not be able to outrun the mutated ancient giant crocodile! Now I can only bite the bullet, hoping that my spiritual enslavement technique can successfully tame this boss!

Turning around and aiming at the target, Yan Fei turned on the skill-Spiritual Servitude Technique!

"Ding! Taming failed! The system's relentless chime rang in my ears.

"Yan Fei, what are you doing?" Qin Yuxin couldn't help but ask when he saw Yan Fei turn around and confront the mutated ancient giant crocodile.

"You deal with him first, I'll withstand its attack, I'll tame it!" Yan Fei said quickly, then stopped making a sound, and then vigorously used the Spiritual Enslavement Technique towards the mutated ancient giant crocodile.

After seeing Yan Fei's movements, Qin Yuxin suddenly understood Yan Fei's thoughts, at this time, the two of them couldn't fight this boss, and the only way now was to rely on Yan Fei's spiritual servitude technique, as long as Yan Fei's luck broke out and tamed the boss, the two of them would naturally be out of danger, and they would even be able to get a powerful assistant!

"Whew!" The roar of the giant crocodile shook the ears of the two people, and the mutated ancient giant crocodile opened its mouth wide at this time and bit towards the two of them!

Qin Yuxin pulled out the Qingfeng Sword and swung a half-moon slash at the mutated ancient giant crocodile, and before the boss got close, the half-moon slash slashed into the mouth of the mutated ancient giant crocodile!

-78, a painless data was generated, and the mutated ancient giant crocodile didn't even pause for a moment, and continued to bite towards the two!

-238, -547, two bright red numbers floated on the heads of Yan Fei and Qin Yuxin respectively! Yan Fei was shocked, Qin Yuxin's defense was not as high as his own, and his health was lower than his own, if he continued to let the mutated ancient giant crocodile bite twice, then he would die soon!

Yan Fei threw Qin Yuxin backwards without thinking, and then resisted the attack of the mutated ancient giant crocodile alone, and continued to use the spirit enslavement technique towards it.

"Ding! Taming failed. ”

"Ding! Taming failed. ”

"Ding! Taming failed. ”

Three times in a row, the system prompted Yan Fei to fail to tame, and Yan Fei continued to use this skill against the mutated ancient giant crocodile.

"Whew!" The mutated ancient giant crocodile seemed to feel threatened, and with a flick of his tail, Yan Fei's whole person was pumped out, Yan Fei was in mid-air, a mouthful of blood almost spurted out, and after forcibly swallowing the blood, Yan Fei's body hit the wall of the cave!

"Poof!" The mouthful of blood had just been swallowed and spurted out. Yan Fei's anger came up, regardless of his injuries, he quickly got up, and continued to use the spiritual enslavement technique against the mutated ancient giant crocodile, today, either you die or I die!

On the other hand, the mutated ancient giant crocodile, since Yan Fei began to use the spiritual enslavement technique on it, the hatred of the giant crocodile has been on Yan Fei, as if Yan Fei is his own enemy, and he has the potential to swear not to rest if he does not kill the other party, because it feels Yan Fei's threat!

Qin Yuxin, who was left behind, was smashed to the ground, and after finally struggling to get up, she was stunned by the scene in front of her!

I saw that the mutated ancient giant crocodile at this moment had more than doubled in size! is constantly crushing towards Yan Fei in the corner! And a string of bright red numbers on Yan Fei's head kept floating, and in an instant, Yan Fei's health dropped by more than half!

"Ahh Qin Yuxin screamed, her eyes red. Seeing that her man was in danger and was about to die, her anger made her lose her mind, and she frantically raised her long sword and slashed towards the mutated ancient giant crocodile!

At this moment, Yan Fei was miserable, pressed under him by the mutated ancient giant crocodile, biting and scratching, his health was constantly dropping, and he couldn't avoid it! He could only grit his teeth and continue to use the Spiritual Enslavement Technique against the mutated ancient giant crocodile.

"Ding! Taming failed. ”

"Ding! Taming failed. ”

Bastard! Is the system a lie? Lao Tzu has failed to tame more than a dozen times, why hasn't he succeeded? Do you really want to die here? Yan Fei began to despair. After catching a glimpse of Qin Yuxin's movements out of the corner of his eye, Yan Fei was shocked and hurriedly shouted, "Don't come here!" Run! ”

Qin Yuxin didn't seem to hear Yan Fei's roar, and still ran towards the mutated ancient giant crocodile, when Qin Yuxin's long sword slashed at the giant crocodile, Yan Fei's heart collapsed to his throat, it's over! Qin Yuxin's remaining health is simply not enough to mutate the ancient giant crocodile to attack two ordinary attacks, if the giant crocodile turns around to attack Qin Yuxin at this time, then Qin Yuxin will definitely die!

-68, a bright red number floated from the giant crocodile's head, Yan Fei thought to himself, it's over, Qin Yuxin is in danger!

How do you know that the mutated ancient giant crocodile didn't care about Qin Yuxin's attack, and bit Yan Fei vigorously, and Yan Fei's health dropped a lot!

Yan Fei was stunned for a moment, and then he was overjoyed, the mutated ancient giant crocodile did not attack Qin Yuxin! But as soon as he thought of the current situation, Yan Fei's eyes dimmed again, according to the development of this situation, the two of them would die sooner or later!

Desperate Yan Fei, the movements in his hands gradually slowed down, and his health was already less than a quarter, and the system still kept prompting Yan Fei to tame failure! It's over, it's all over!

"Ahh Seeing that Yan Fei's health was about to bottom out, Qin Yuxin suddenly became hysterical, and actually pounced forward, hugged the tail of the mutated ancient giant crocodile, and then pulled hard, trying to pull the giant crocodile off Yan Fei's body!

"Don't!" Yan Fei was shocked, and as soon as he shouted out his words, the tail of the mutated ancient giant crocodile flicked out, and he threw Qin Yuxin out and hit the wall of the cave!

Qin Yuxin's body smashed against the wall, her health bottomed out in an instant, and then her whole body slid down the wall to the ground, and there was no sound.

"No!" Yan Fei roared in pain, strong unwillingness surged out of his heart, and then he was overwhelmed by endless anger! At this time, Yan Fei's hatred for the mutated ancient giant crocodile on his body reached its peak!

Bastard! Lao Tzu fought with you! Yan Fei roared in his heart, the telekinesis control skill was activated, and more than half of the mana was instantly extracted, and a powerful shock wave formed in his chest, and then shot directly at the mutated ancient giant crocodile on his body
