This is why Yu Cheng felt something strange underground before.

In the safe house.

Yu Cheng simply cleaned the dishes and chopsticks.

Turn around and look at the cave clock in the corner.

Cave clock records.

1:47 p.m.

The number of shovel can be used: "Er".

Xiaofen was not too anxious, but was still slowly licking the foreign body blood in the iron bowl.

"Gu..."

Satisfied with the feeling of satiety, Xiaofen touched his belly and belched contentedly.

Underground.

The field boss began to turn his body and try to make himself over.

Yu lingxuan disappeared slowly, and there was an illusory foreign body shadow in her right hand.

Immediately, the whole body is like a squid like field boss constantly rolling up, about to break through the color barrier above

What's going on?

At this moment, Yu Cheng is at the door of the safe house. The underground barrier is continuous, and the protrusions are constantly changing. The wrists first drill out from the ground, one by one, and then appear in the space.

Xiaofen drinks all the foreign body blood in the bowl into his stomach.

Then he appeared in front of Yu Cheng and stared at several wrists outside the safe house.

What surprised him was that the relatively solid underground barrier was suddenly broken, leaving only the color barrier that set off the safe house.

The body of the field boss also completely emerged in the cave. Most of the previous wounds are now intact without any trace.

Yu Cheng reached out, touched the corner of the safe house, pulled out the three color bone knife, and then looked at the powder.

Then, the gray gas slowly spread out from Xiaofen's body and wrapped Yu Cheng's whole body.

[system prompt]

[skill sharing]

[instantaneous movement] [flight]

——

The blue screen did not disappear directly this time. On the contrary, the pet panel also appeared in front of Yu Cheng at the moment.

[current pet is about to break the critical value]

[required boss foreign body blood]

[promotion level: intermediate]

——

In other words, the boss in this field years ago is just the best promotion nourishment at the moment.

Xiaofen seems to have known for a long time, rubbing his claws secretly.

Yu Cheng, holding a tricolor bone knife, moved his feet, and the transparent wing feather behind him quickly opened, which took his body to the sky in a flash.

The original intact colorful sand has become thousands of holes, and the only surviving place is a small area protected by the safe house.

Xiaofen also disappeared into the safe house in an instant. He followed Yu Cheng's back and didn't get bigger directly. Instead, he was on the side and became a bystander.

The cave arms are all open at the moment, and the helmet is also the available condition for automatic triggering. The only unused cave breastplate began to shake constantly.

Yu Cheng didn't let him participate. He wanted to test the maximum bearing value of protective clothing.

According to the previous articles, protective clothing is only a disposable product, which can only withstand a fatal blow

The most corner of the space.

Yu lingxuan hid her body in the darkest part of the space and avoided Yu Cheng's current vision.

In her hand, the shape of the small transparent foreign body kept rolling, and the corners of her mouth inadvertently rose at the moment.

Then, Yu lingxuan took out a small bottle like object from the bracelet, and the white transparent foreign body was sucked in instantly.

[system prompt]

[hide task completed]

[reward cave intermediate weapons]

——

The blue ball of light appeared on her palm.

Sure enough

The method is feasible.

As for the huge field boss in the space at this time, he is like a walking corpse, constantly waving his wrist.

The original fast and accurate attack seemed to forget the brain and began to hit instinctively at will.

Yu Cheng clenched the tricolor bone knife in his hand and was alert to the strange characteristics of the foreign body in front of him.

It is inevitable that it may be his confused behavior.

The transparent wings danced and immediately disappeared into the space with Yu Cheng's whole body.

The next second, the illusory black shadow of the white bone knife appeared on the back of the foreign body and waved down mercilessly. Black and red blood sprayed out at the moment and dyed the whole blade red.

Xiaofen's body became bigger in an instant, came to the foreign body in an instant, and pinched all the disorganized wrists together.

The whole process was without any resistance.

"Master, it's stupid."

The soft tone came into Yu Cheng's ear, explaining the situation at this time.

Stupid?

Yu Cheng gripped the bone knife, stabbed the foreign body in an instant, and then pulled it out. The blade was still black and red foreign body blood.

Familiar colors are often materials or creatures related to black and red, which are not as simple as imagined.

Yu Chengshan returned to the safe house with the bone knife. Everything went so smoothly that it was abnormal.

Instinctively, the boss in the field of dead dragging with himself suddenly rushed to the ground like a fool and appeared in front of him. What's more surprising is that his strength was greatly reduced.

Compared with the past, even the foreign bodies in the secondary unknown field are much stronger than the current boss in this field.

Xiaofen didn't think too much. He knocked out the foreign body's head with a claw, and then bit it above its neck.

It is a class III foreign body.

I saw that while taking the powder, the foreign body was in a coma, woke up instantly, and then struggled and resisted.

The results are self-evident.

Xiaofen waved his huge claws and came up and down on his forehead. The black and red blood kept flowing down to the foreign body's wrist.

There was only one last breath left.

To be on the safe side, in order not to be disturbed and suck blood, Xiaofen took the foreign body to one side in front of the intact barrier, stored his strength, held his fist back, and directly blasted the boss's head.

The black and red blood was covered with powder and half of his claws. After he was confirmed dead, he began to wave his wings and suck at ease.

Safe house.

After Yu Cheng confirmed the death of the field boss through hyperopia, he didn't think much and began to prepare to consider the integral lottery.

The blue screen also appeared in front of him as if he had already understood his inner thoughts.

[system prompt]

[domain boss has fled]

[current domain task failed]

[cancellation of award issuance]

——

The white subtitles kept sliding.

Yu Cheng rubbed his eyes to make sure he was right.

Then, through hyperopia again, look at the picture direction of Xiaofen eating.

Huh?

That's right?

Isn't this dead?

……

Far away. Xiaofen is particularly satisfied with licking his lips, but it feels strange that he thought he could evolve and upgrade this time, but he hasn't moved for a long time.

In its pet upgrade bar, although the experience has increased, it is far from enough.

Is the blood of the boss in the tertiary field far from enough to upgrade?

In the dark corner, Yu lingxuan shook the vial, smiled again, and then closed her eyes.

Innocent eyes reappeared
