(The collection is about to break 5,000, and now there is a lack of cute masters, which little partner will shake his arms and drink, come and take the lead!!) ）

If these zombies are allowed to get close, even if it is one, Guo Jin will definitely suffer.

The zombies' bodies were all facing Guo Jin's side.

Opportunity!

Li Yan took a deep breath, held it, jumped up one by one, and slashed at one of the zombies.

Gorgeous oblique slash, hit the key point without suspense.

"Puff~"

With a bang, a zombie was eliminated.

However, Li Yan's move attracted all the attention of those zombies, and the remaining four or five zombies turned around and pounced on him.

Dealing with one, Li Yan held his breath and was still sure, he would definitely not be able to carry four or five at once, so he turned around and ran back.

"Whoosh, whoosh~"

There were two clear sounds, Li Yan just started running here, and Guo Jin's arrows over there shot extremely accurately.

The two zombies fell in response, because they were shot from the back of the head, and fluttered forward, just hitting the two in front of them.

The two zombies who were hit howled and turned around, and when they saw Guo Jin, they suddenly put down Li Yan again, turned around and pounced over there.

Li Yan kept looking back when he ran, and when he saw the zombie pounced back, he hurriedly braked on the soles of his feet, turned around and killed, and ran to the zombie who fell behind.

Almost at the same time, Guo Jin also drew his bow and shot another arrow.

"Puff~"

With a bang, the two zombies were killed by Li Yan and Guo Jin.

A long-range attack, a close attack, perfect coordination.

The two of them looked at each other and smiled very tacitly.

Five or six zombies were pulled out here, and the pressure on Xiaoshui and the female jumping corpse suddenly decreased.

Although the remaining zombies are still thick-skinned and thick-skinned, they were still caught by Xiaoshui and had the opportunity to lie down three or four, and the female jumping corpse was also evenly matched.

Li Yan suddenly joined the battle group again at this time.

With the experience just now, he brought out five or six zombies, and cooperated with Guo Jin to overturn them according to the gourd drawing.

After a few back and forth, the twenty or so zombies that pounced out of the stone house all moved their heads in a short time.

As soon as the battle ended, Li Yan's mind flashed the system's prompt information.

"Corpse Keeper System Upgrade..."

"Holder: Li Yan..."

"Current Controllable Corpse Level: 3..."

"Kill lv5 level zombies +15, ability points +750..."

"Currently has Lv0 Flying Corpse +1, Lv0 Jumping Corpse +1, Lv0 Purple Zombie +25..."

"Congratulations to the system holder, the current ability points have exceeded 100, do you choose to mutate and upgrade the purple zombie..."

Are these zombies lv5?

Li Yan was a little confused, the old zombie before was also lv5, but its speed was very fast, but these in front of him seemed to be another extreme.

It's like, one is a killer, one is a warrior, one is the main attack, and the other is the main defense.

It seems that the evolution of zombies is not static, and the evolution of zombies of the same level is not in the same direction.

Thinking of this level, he was a little secretly glad in his heart, fortunately the two styles of zombies did not stay together, otherwise he would have to put a lot of thought into dealing with them.

"Please do the system holders choose to mutate the purple zombie upgrade..."

The prompt information in the system flashed in his mind again, pulling Li Yan back from his thoughts.

Let's try again when we have enough experience points.

An idea flashed through Li Yan's mind.

"If the system holder chooses no, the odd number of abilities will be accumulated, and the current number of ability points is 1500..."

1500？

By the way, when he was in the morgue, he devoured the corpse crystal for Zi Zombie, which was a one-to-one devouring, because it was evenly distributed, and the system did not have a message to prompt that twenty-five lv3 level corpse crystals, plus 750 just now, was exactly this number.

Well, let's save it first, it won't be lost anyway.

After thinking about it, Li Yan followed with a saber to dig up the corpse crystal.

Guo Jin had already walked over in front of him, and when he saw Li Yan's next move, he consciously turned his head away.

Li Yan's movements were very fast, and he was familiar with the road, and he quickly took out the corpse crystals in the zombie's head, almost twenty-seven or eight.

After putting all the corpse crystals in the bag on his back, he called out to Guo Jin, pointed to another stone house, and motioned to continue.

Guo Jin nodded, took a deep breath, wound the arrow, and signaled Li Yan to finish his preparations.

The baptism just now, although it was a little difficult, seemed to have freed him from the shadow of murder.

Li Yan walked to the stone door, and with his previous experience, he quickly opened the bolt of the stone door.

Unlike the stone house on the left, as soon as the door opened, the zombies inside rushed out in piles.

With a foul smell, the smoker was sick to his stomach.

Fortunately, those zombies are not much different from the previous ones, and their movement speed is not too fast, it is nothing more than a few more slashes.

After this toss, after the zombies inside were eliminated, Li Yan's arms trembled uncontrollably like his legs when he climbed to the top of the mountain and walked downhill.

The arrows in Guo Jin's quiver have almost been consumed, and only two are left.

But fortunately, none of the zombies outside the stone house are still standing.

A series of prompts flashed through my mind.

"Corpse Keeper System Upgrade..."

"Holder: Li Yan..."

"Current Controllable Corpse Level: 3..."

"Currently has Lv0 Flying Corpse +1, Lv0 Jumping Corpse +1, Lv0 Purple Zombie +25..."

"Kill lv4 level zombies +5, lv5 level zombies +10, ability points +700..."

"Congratulations to the system holder, the current ability points have exceeded 100, do you choose to mutate and upgrade the purple zombie..."

Not.

Li Yan naturally made a choice.

"If the system holder chooses no, the odd number of ability will be accumulated, and the current number of ability points is 2200..."

It's more than 2000 points, this is really fast enough, I thought it would be a big project, but I didn't expect to encounter this pile of high-level zombies, and get twice the result with half the effort.

And there are a lot of corpse crystals that are not used, this trip back can not only collect those two flying corpses, but the extra ability points can also be used by Zi Zhuang to upgrade.

It's really a good receipt.

Li Yan was overjoyed in his heart, and began to collect corpse crystals with his saber.

"Woo~"

At this moment, a gust of wind came from nowhere, blowing the torches, and the flames were much lowered.

Guo Jin mentioned before that this cliff crack is naturally formed, not completely occluded, there are rock crevices in some places, but because it is in the cliff body, it can't shine in the light.

Li Yan didn't care too much, just glanced at the torch that was not blown out, leaned down and continued to collect corpse crystals.

He happened to be walking outside the door of the stone house at this time, and there was a lv5 zombie lying there.

He poked the zombie's head open, leaned down and reached for a corpse crystal.

His body tensed suddenly.

Suddenly a special smell filled the air near the stone gate.

To him, the smell was still a little familiar.

He sniffed vigorously.

It's not the smell of a latrine.

It's a little stronger than that, and there's a hint of sourness.
