The craziest upgrade system

Nie Yun had never thought that the black python would actually hunt for prey, but unexpectedly, after hearing this, the black python turned around and ran into the primitive jungle.

Not long after, the black python came back with two huge goats and threw them in front of Nie Yun.

Then he confided in Nie Yun, as if to say, the prey is here, you can figure it out yourself.

At this point, there was nothing he could do, so Nie Yun had no choice but to take out his dagger and start handling the goat. The goat weighed several hundred kilograms, and it took a lot of effort to handle it.

After processing it, I put it on the grill and started grilling it. It was originally going to be marinated, but now there are no conditions, so I'll just make do with it.

Almost half an hour later, the roasted deer was ready. Nie Yun used a dagger to cut off a small piece of mutton, and threw the rest to the black python.

The big mouth opened again and again, chirp, chirp, chirp...

After the black python finished eating, it must have been full or something. This time, it didn't look at Nie Yun. Instead, it turned back to the place where he was basking in the sun, closed its eyes and began to rest.

Seeing this, Nie Yun thought about putting the other stag into the storage bag.

But something embarrassing happened and I couldn't take it in.

Because the storage bag only has one cubic meter of space, even if Nie Yun took out all the things he had put inside, he still wouldn't be able to fit a deer weighing several hundred kilograms!

Nie Yun looked at the giant deer in front of him and had a headache. Adhering to the principle of never wasting anything, Nie Yun could only dismember the giant deer.

Only four deer legs were left in the storage bag, and the remaining parts were roasted and treated as tomorrow's breakfast for himself and the black python.

As for the deer legs, you can always keep them in the storage bag, because there is a vacuum inside, so they won’t go bad if you keep them for a long time, but you can’t store live animals in them.

Nie Yun spent the past two days quite comfortably. Anyway, if he wanted to eat, the black python would get the prey, and at Nie Yun's strong request, the prey would be brought half-dead to him.

In the remaining time, he will concentrate on studying the "Seven Kills with the Wind Knife". Each of these seven kills has made Nie Yun very proficient in practicing them.

This is just seven kills combined into one, but it is very difficult. At present, Nie Yun has not even touched the threshold of the most basic two kills combined into one.

Two kills combined into one, that is to say, the combat power is increased by four times in an instant!

If a warrior at the second level now bursts out with four times his combat power in an instant, the warrior will have to avoid its sharp edge in the later stages!

If you can directly reach the level of seven kills in one, your combat power will increase by 49 to [-] times in an instant.

It is estimated that it is not impossible to cross a great realm, instantly kill the martial arts master, or even seriously injure the martial king!

It's just to achieve seven kills in one, that's all I think about now.

I don't even understand how to combine two kills into one.

At noon on the third day, the yin and yang fruit was about to mature, surrounded by spiritual energy, and the aroma of medicine had filled the entire valley.

The black python shook its head and stared tightly without moving, for fear of missing the opportunity for the Yin Yang Fruit to mature.

But at this moment, a crane chirped through the clear sky. Hearing the sound, the black python suddenly raised his huge head and looked at a white crane hovering in the sky!

Where is Nie Yun at this moment?

As early as the second when Bai He appeared, Nie Yun fled hundreds of meters away. After putting enough distance between him and the two, he hid and began to watch from the sidelines.

The White Crane who could kill him at this time was definitely not an ordinary person, and to make the Black Python so nervous, it would have to be a Monster Crane who was also at the peak of the sixth level!

As expected, the White Crane was condescending and took the lead in attacking. He flapped his wings and set off gusts of wind, which was fierce.

The big tree on the side, with three or four people hugging it, was not blown down as expected. Instead, it was riddled with holes and devastation, and finally broke directly to the ground.

The black python in the center of the attack range naturally felt uncomfortable, but the dark scales on his body protected him very well.

Then the black python raised its upper body, and the flesh and blood under the dark scales turned red, as if the blood vessels inside were flowing not with blood, but with red magma!

Opening its big mouth, a huge flame spurted out from the black python's mouth toward the white crane!

The ensuing heat wave made Nie Yundu, who was several hundred meters away, feel slightly uncomfortable.

"Damn it, these two monsters are so fierce!"

Then he retreated another few hundred meters.

Just kidding, these two guys are so scary. If we stay away from each other, if one of their big moves hits me later, wouldn’t it be too unfair for me to die?

But it's a pity that Black Python missed this move.

Bai He just dodged the blow slightly.

The white crane's attack could not break through the defense, but the black python's attack failed to hit.

The situation was so deadlocked.

But time waits for no one, and the surrounding aura is getting stronger and stronger. The Yin Yang Fruit is about to mature. If it is not picked within a quarter of an hour after it matures, it will fall, merge with the soil, and dissipate. In heaven and earth!

One Snake and One Crane are naturally very anxious. After the Yin Yang Fruit matures, if it cannot be eaten immediately within a quarter of an hour, it will be wasted!

Both of them also opened their spiritual wisdom early, so they naturally knew the characteristics of the Yin-Yang Fruit.

There was no other way. In order to break the deadlock, the white crane swooped down from the air and attacked the black python. Not to be outdone, the black python fought back by swinging its huge tail!

As the ripening time of the Yin Yang Fruit gets closer and closer, one snake and one crane begin to fall into a fight. If they don't fight to the death, it may not end.

However, Nie Yun also understood that the snake and the crane were natural enemies. Now with the addition of a Yin-Yang Fruit, there would definitely be a winner between the two today!

As the battle entered a fierce stage, the injuries on Yi Snake and Yi Crane also increased.

The black python was scratched in many places, bones were visible everywhere, and many dark scales were ripped off alive and scattered on the ground.

On the other hand, Bai He's injuries were not optimistic either. He had lost a lot of feathers and was lame on one foot. A large piece of flesh and blood was torn off one of his wings by a black python!

As the surrounding spiritual energy continues to pour into the body of the Yin-Yang Fruit, until it is completely concentrated and no longer absorbs spiritual energy, the Yin-Yang Fruit is completely mature at this moment!

Unable to care about that much, Bai He broke free from the restraints and flew towards the Yin Yang Fruit.

But how could the black python do as he wished?

He opened his mouth fiercely, bit the white crane, and tightly wrapped around it, not giving him any chance.

The snake and the crane were so entangled, and the Yin-Yang Fruit only had a quarter of an hour to mature, so they all began to fight hard!

The battle became more and more fierce, and the earth trembled!

As time slowly passed, after 5 minutes, the fighting momentum between the snake and the crane was no longer as good as before. Both of them were at the end of their efforts to hold on with their strength, but they just couldn't hold on with that breath without falling down. .

Although Nie Yun was also very anxious at the moment, the fighting power that the snake and the crane now exploded was still not something that Nie Yun, a small second-level warrior, could withstand!

Another minute passed, and the snake and the crane were still fighting each other.

Another minute passed, and both of them were left with more air coming out and less air coming in. They both fell limply to the ground, still glaring with anger. If eyes could kill, they would like to kill each other with their eyes!

Nie Yun knew that the opportunity had come. At this time, there were still 7 minutes left before the Yin Yang Fruit fell, but he could no longer be impulsive. After all, as long as these two big guys still had energy left, he would be in bad luck.

Another minute passed, and there were only 1 minutes left before the Yin Yang Fruit fell. One snake and one crane were still lying on the ground, tightly intertwined, but their breath was getting weaker and weaker.

Seeing this, Nie Yun finally relaxed and immediately used the Earth Escape Technique, with a clear goal, and flew towards the Yin Yang Fruit...
