Just when Yu Feng was thinking that one of the skeleton undead monsters would explode something, a sea of white skeletons, which had already locked on to Yu Feng at this time, let out bursts of "creaking" bone friction sounds, sharp and piercing, and moved towards Yu Feng.

Yu Feng didn't know how many times he had just gone in and out, but seven or eight times was definitely there. Every time, more than 1,000 skeleton undead monsters are refreshed, and seven or eight times is equivalent to refreshing seven or eight thousand skeleton undead monsters, and only then can such an undead hourglass be refreshed.

Roughly estimated, the explosion rate of almost 1 in 10,000 should be a good thing!

But good things belong to good things, how to burst out good things, and then take out good things, this has become a big problem that Yu Feng has to consider!

The army of skeletons and undead like a tidal wave, not to mention rushing in and killing that skeleton undead monster, even if Yu Feng had a way to go in and kill that skeleton undead monster, how to pick up things and then exit safely has become another thorny problem!

"Hey, Wind, you...... What are you doing in a daze, don't scare me, those big skeletons are here~" Just as Yu Feng lowered his head and groaned, Meng Feifei, who was standing behind, gently tugged Yu Feng's arm and said timidly.

Hearing the voice behind him, Yu Feng looked back at Meng Feifei, smiled, and in order to avoid some unnecessary trouble, he turned his head and casually pointed to one of the skeleton undead monsters on the opposite side: "Feifei, I just observed and found something different." Look at it, see if you can see that the monster doesn't seem to be like the others. ”

Meng Feifei hid behind Yu Feng, peeked at the direction of Yu Feng's finger, shook his head and said, "What's the difference!" ”

"Take a good look~" Yu Feng put on a serious attitude and said solemnly.

Yu Feng was also helpless, after all, his ability to see the source code could not tell anyone. If he abruptly went up and identified one of the skeleton undead monsters, even if Meng Feifei would not notice anything now because he was afraid, he would definitely suspect it afterwards.

Instead of being so troublesome, Yu Feng felt that it was better to leave such a psychological hint at the beginning, which made Meng Feifei feel that it was because he accidentally discovered the difference, so he recognized the shot and could avoid some unnecessary trouble.

Guided by Yu Feng's psychological suggestion, Meng Feifei first looked at those skeleton undead monsters with a discriminating presumption, and finally said ambiguously: "Hiss...... It seems like...... It seems to be a little different, too...... It's not different, oops, I don't know if it's different! ~”

At this time, a large number of skeleton undead monsters had moved to the entrance of the ancient castle here, blocking the entrance, so that Yu Feng could not use it even if he had a way, so he could only retreat to the outside of the boundary with Meng Feifei.

"Bang ~ "

There was a crisp sound of bones colliding, and the skeleton undead monster that was still full of eyes before disappeared in the blink of an eye.

Looking at Meng Feifei beside him, Yu Feng opened his mouth and said, "You will be waiting for me outside for a while, I'll go in and try it and see if I can break through." ”

Meng Feifei originally had no idea, and when she heard Yu Feng's meaning, she seemed to have some way to open her mouth and ask, but seeing that Yu Feng didn't want to tell her the idea, she turned her head directly, and couldn't help but pout, looking at Yu Feng's back angrily, with an unhappy face.

Hmph, this stupid wood! Big pervert!

After settling Meng Feifei, Yu Feng stepped into the Dao boundary with one foot, and the skeletal undead monsters refreshed out one after another with the sound of the soil breaking.

After sweeping his eyes, this time the skeleton undead monster was not refreshed, and Yu Feng stepped out of the hall again.

Go in, no, go out...... Go in, no, go out...... Go in, no, go out......

After tossing thirteen or fourteen times in a row, Yu Feng's eyes finally found the target he wanted to see.

[Skeleton Axe (Undead), Level 15, HP 1800/1800, Attack 580-580, Defense 20-20, Alert Range...... Skill Undead Eternal: After death, it will be revived immediately for ten seconds. After death, an undead hourglass bursts. 】

The central square of the entire Casamen King burial place occupies an area roughly like a round dial. If the position where Yu Feng and Meng Feifei were standing at the entrance at six o'clock at this time, then the position refreshed by this skeleton axe hand was located at the midpoint between the center of the dial and the line between the one o'clock position, which was not too ideal.

After hesitating for a moment, Yu Feng finally gave up on this skeleton axe hand and stepped out of the skull again.

The central square in front of me was once again empty.

In the next five minutes, Yu Feng didn't know how many times he had tossed back and forth, and finally after stepping in one foot at a time, he saw a skeleton necromancer that could burst out of the undead hourglass again.

[Skeleton Swordsman (Undead), Level 18, HP 1500/1500, Attack 700-700, Defense 20-20, Alert Range...... Skill Undead Eternal: After death, it will be revived immediately for ten seconds. After death, an undead hourglass bursts. 】

It's not good luck or bad luck, the monster that can burst the undead hourglass this time is a skeleton swordsman with high blood and thin blood.

Only this time, this skeleton swordsman refreshed near the line between the center of the circle and the seven o'clock position, and it was closer to seven o'clock, and it was already very close to Yu Feng and Meng Feifei's side!

That's it!

With a decision in his heart, Yu Feng glanced at his skills. Since the Jedi Glow, which requires a cooldown of two natural days, it is now possible to ignore it. The only skill that can be used, Yu Feng roughly knew it, and rushed in decisively.

Demon Noh Stone!

Yu Feng first activated the active skill of the Demon Stone, and summoned a replica demon shadow that was exactly the same as himself by his side.

Immediately after, Yu Feng's mind moved, and he controlled the Replica Demon Shadow to rush into the central square first, starting from the position of six o'clock, and ran in a counterclockwise direction towards the position of five o'clock.

Sensing the strong aura of life, a large number of skeleton undead monsters began to move slowly in the direction of the replicating demon shadow.

Meng Feifei suddenly saw that there was an extra "Yu Feng" next to Yu Feng, and whether it was the appearance or figure, it was exactly the same, and she couldn't help but be surprised. When he saw Yu Feng's next move, he was immediately overjoyed. I thought that if there was one person like this to lure away those skeleton undead monsters, then the two of them should have enough space to rush in.

But soon, the cruelty of reality shattered this beautiful idea of Meng Feifei.

Even though the skeleton necromancers were attracted by the replica shadow, the central square was only such a large area after all, and those skeleton necromancers could squeeze to one side with a slight movement. On the other side, there is very limited space to spare.

Almost negligible.

Seeing that this was the case, Meng Feifei, who was originally overjoyed, suddenly dimmed her eyes.

It still doesn't seem to be a show......

Meng Feifei, who was helpless, couldn't help but feel the idea of giving up. Looking at Yu Feng's back, he said in his heart that when he finished the test, it was better to give up first. Go back and wait until you're a little higher, and then try again.

Yu Feng, who didn't know what Meng Feifei was thinking, was staring at the moving army of skeletons and undead intently at this time. And the Replica Demon Shadow, which rushed out of the corpse by itself, has now finally collided with the army of skeletons and undead.

The 10% maximum health shield provided by the Demon Shadow Stone, which is a shield of 165 energy, was shattered by a skeleton swordsman in two clicks. However, the Replicator also used the long sword in his hand to successfully harvest the three skeleton necromancers.

As the skeleton undead army moved little by little, the skeleton swordsman that Yu Feng was staring at was finally exposed from the skeleton undead army little by little.

Four...... Three...... Two......

When there were no other skeleton undead monsters between the skeleton axe man and Yu Feng, Yu Feng decisively raised his feet and rushed into the central square.

Charge Valiant!

A long-distance rush skill, Yu Feng quickly crashed into the side of the skeleton swordsman.

－80！

－2！

－81！

－2！

－80！

－2！

……

After a small patch of area damage, several bright red numbers floated above the heads of a circle of skeleton undead monsters around them. Yu Feng's blow instantly pulled the hatred of several skeleton undead monsters around.

Ignoring this, Yu Feng grabbed the target skeleton swordsman with his right arm, rushed forward half a step, and smashed it the body of a skeleton warrior behind him. Because it didn't hit the wall, it only caused a damage effect, and it didn't hit the stun state.

－148！

－4！

Warcry!

With a roar, Yu Feng launched the Battle Cry skill, and after increasing his physical damage, the source code information in his eyes fed back, and the surrounding skeleton undead monsters attacked him one after another!

Taking a step back, Yu Feng narrowly avoided the siege and gained enough rage points at the same time. With a tight left hand, he slammed the tower shield in his hand!

Flying Shield Assault!

The huge tower shield instantly flew into the group of skeleton undead monsters, smashing out a "knock knock" crashing sound.

－163！

－4！

－170！

－6！

－160！

－4！

……

The bleeding state is combined with the output skill, and a large number of bright red numbers float again. At the same time, on the heads of the skeleton necromancers, there is a sign of vertigo.

Rampage!

The skill burst into succession, and Yu Feng took a leap forward, directly crashing into the target skeleton swordsman.

－132！

－8！

Sword stabbing normal attack.

－110！

－10！

Straight hit!

－260！

－10！

Vertigo!

Sword stabbing normal attack.

－111！

－10！

Thunder Strike!

－225！

With a series of blows, Yu Feng directly knocked out the target skeleton swordsman with more than 1,300 lives.

After all, it was still level suppression, and the equipment couldn't keep up, Yu Feng was already very content to be able to achieve these outputs.

There are less than 200 lives left!

At this time, the target skeleton swordsman was still in a stunned state, while the surrounding skeleton undead monsters had recovered from the stunned state and attacked Yu Feng one after another.

The left-hand tower shield crossed the attack on the left, and the long sword in Yu Feng's hand connected the dots, and after taking a few hard hits of the skeleton undead monster's attack, he finally emptied the life of the target skeleton swordsman in one go.

With a "bang", the skeleton swordsman who had not yet shot was directly shattered into a pile of white bones, and disappeared into the dirt in the blink of an eye, leaving only an hourglass about ten centimeters high on the surface.

That's it!

Yu Feng's eyes lit up, he bent down to pick up the items that exploded on the ground, and took two more attacks from the skeleton undead, and when he still had more than 400 points in his blood, he quickly withdrew from the battle circle.

Bite!

System: You picked up the Undead Hourglass.
