The fourth level is not like the first three levels, there are no hints, and this level has clearly given a hint, that is, you need to kill a level 120 undead.

In the case of not being able to use the undead summoning, under normal circumstances, Qin Wen would definitely not be able to meet this requirement, so it was obvious that in the underworld, he would definitely be able to find a way to improve his strength.

Just like in the second and third levels, Qin Wen's liliang and agility can't be cleared at all before he finds a way, but after finding a way to improve his attributes, as long as he continues to enhance his strength, he will be able to clear the level sooner or later.

So now Qin Wen's primary purpose is to find a way to improve himself.

After walking for a short time, Qin Wen finally saw a living thing, or a dead thing, on this buried bone land.

It was a skeleton soldier, as one of Qin Wen's troops at the beginning, successfully summoning a skeleton soldier could be said to be the first step for him to make a fortune, so Qin Wen was naturally no stranger.

In the hollow eyes of this skeleton soldier, two green flames were beating, and the green flames seemed a little faint, as if they would be extinguished when the wind blew.

Qin Wen knew that it was not a real flame, it represented the soul liliang of the skeleton soldier, the weaker the undead, the weaker the soul liliang had, like the skeleton soldier who was at the lowest level, the two flames were like candles about to be extinguished.

Conversely, the more powerful the undead, the stronger the soul liliang will have, and the more condensed the soul flame will be.

As Qin Wen approached, the thin skeleton soldier sensed Qin Wen's arrival, and made a piercing sound of "click", waving the broken knife in his hand that he didn't know where to go, and walked towards Qin Wen fiercely.

A mere skeleton soldier was naturally not in Qin Wen's eyes, and he originally wanted to study it to see what the difference between this skeleton soldier in the underworld was different from the skeleton soldiers he usually summoned.

But I didn't expect this guy to be so unfriendly, and he wanted to make a move on Qin Wen as soon as they met.

In desperation, Qin Wen could only choose to destroy it.

Although there is no undead legion by his side now, Qin Wen is also a sixty-eight-level existence, and in the face of a mere tenth-level skeleton soldier, he can be killed in an instant.

Before the skeleton soldier arrived, Qin Wen's magic sword swung and shot a shadow arrow, stabbing at the skeleton soldier's body.

The damage value of a red word floated from the skeleton soldier's head, and the skeleton soldier suddenly fell to the ground, and the broken knife in his hand also fell to the ground, killing instantly without suspense.

Qin Wen shook his head, looking a little bored, and was about to move on, but suddenly found that a green ball of light had condensed on the skeleton soldier who had just hung up, but the light was very dim, if it weren't for the dim light here, Qin Wen probably wouldn't have seen it.

This sudden change immediately aroused Qin Wen's interest, and he was about to study it carefully with great interest, but unexpectedly, the still green ball of light actually moved, and shot directly at Qin Wen's body.

Qin Wen was suddenly startled, and subconsciously wanted to dodge, but the speed of the ball of light was too fast, and he had just moved the idea of dodging, and the ball of light had already shot over, and the moment it touched Qin Wen's body, the strange thing was that the ball of light was directly integrated into Qin Wen's body.

After the ball of light fused, Qin Wen instantly felt refreshed, and his mind became extremely clear!

Except for this change, Qin Wen didn't find any other changes, and as for the damage, there was no damage at all.

After knowing that he would not cause harm to himself, Qin Wen was relieved, no matter what, it was harmless to himself anyway, and after integrating into that ball of light, Qin Wen felt quite comfortable.

This made Qin Wen more interested in the green ball of light just now, and he faintly felt that this thing had a lot to do with his customs clearance.

"The dim green ball of light, could it be the soul of the skeleton soldier just now?" Qin Wen thought to himself, the eyes of the two were so close, he naturally thought of this first, and the more he thought about it, the more reliable Qin Wen felt.

"The first level increases wisdom, the second level adds liliang, and the third level is agility, is this fourth level the soul?"

"No, the soul is a bit ethereal, it shouldn't be the soul, is it the spirit? It's like this, I just felt very mentally refreshed. ”

"It's just that if the spirit increases, how come your attributes haven't changed?"

Qin Wen kept calculating, the more he thought about it, the more he felt that it was like that, as for his attributes had not changed, he guessed that it might be because the soul of the skeleton soldier was too weak, after all, he was almost seventy level existence, and a mere level ten undead was already good if he could make himself feel refreshed, and if he wanted to increase his spirit, I am afraid it would be difficult.

After figuring out this section, Qin Wen became more and more motivated, and he was also anxious to know the effect of this ball of light to see if it was the same as he had guessed.

The founding leader said that practice is the only criterion for testing the truth, and the leader's words must be reasonable, Qin Wen decided to strictly follow the leader's words, whether it is true or not, then give it a try and know.

Maybe Qin Wen was getting closer and closer to the center of the burial place, and this time it didn't take long for Qin Wen to encounter the wandering undead again, and there was more than one.

A skeleton warrior, with three skeleton soldiers, swaggered around not far in front of Qin Wen.

The skeleton warrior took the lead in the front, and the three-headed skeleton soldier followed behind, not daring to overstep in the slightest, so that Qin Wen saw that it was a little funny, in the underworld, the difference between this level was really very strict, and even this skeleton warrior could accept a few skeleton soldiers who were lower than himself as a junior brother.

He didn't make the first move, but looked at the situation, and as expected, the color and brightness of the green flames in the eyes of these three skeleton soldiers were about the same as the previous one, and obviously, their souls were not much different.

And the soul liliang of the skeleton warrior in front of him, although it is still nothing, but compared to the skeleton soldier, the brightness is much stronger, which can be regarded as confirming some of Qin Wen's previous guesses.

A spirit explosion spell was condensed in his hand, and it exploded near the skeleton warrior, and immediately hung up the skeleton warrior and the two skeleton soldiers, with their little defense and blood, how could they block Qin Wen's attack.

It's just that because the Spirit Explosion Spell is only a small group attack skill, the range is very small, and the other skeleton soldier is a little far away, so it was not blown up by the attack of the Spirit Explosion Spell and survived, but its "boss" suddenly died, which made this skeleton soldier a little dazed for a moment, and he didn't know what was going on.

And immediately after, Qin Wen shot out another shock technique, and solved the skeleton soldier in a daze.

This time, Qin Wen paid special attention to the situation after the four undead hung up, the familiar green ball of light quickly condensed on the bodies of several undead, the ball of light condensed by the three skeleton soldiers was the same as the previous one, and the only skeleton warrior, the condensed ball of light, was obviously brighter, I was afraid that the soul liliang of the three skeleton soldiers combined was not as strong as the soul liliang of this skeleton warrior.

Looking at these four balls of light, after waiting for a long time, they hadn't taken the initiative to fuse into his body, Qin Wen was a little puzzled, but under this thought, the four balls of light moved, rushed towards Qin Wen quickly, and took the initiative to integrate into his body.

Qin Wen suddenly realized that this soul light ball would not look for a target by itself, but needed to be actively absorbed by others before it would be projected.

The four balls of light were like bodies, and a familiar feeling came, and the comfortable feeling made Qin Wen feel as if he had just finished XX, and couldn't help but let out a comfortable moan, this kind of refreshment from the soul was not comparable to ordinary feelings.

I checked my attributes again, there was no change, at this time Qin Wen no longer doubted his guess, since the attributes had not changed, the only possibility was the soul of the skeleton warrior, it was still not enough for Qin Wen to improve, and a more advanced undead was needed!

Leaving behind the corpses of the four skeletons, Qin Wen continued to move forward.

Along the way, skeleton soldiers and skeleton warriors appeared more frequently, and there were also some low-level undead such as skeleton mages and skeleton archers, but Qin Wen was too lazy to take the initiative to find trouble with them, since they were no different from enhancing their strength, then naturally there was no need to waste time, unless they didn't open their eyes and took the initiative to come up to Qin Wen's trouble.

And along the way, Qin Wen also had a better understanding of the life of these undead in the underworld, and even he saw the battle between the undead, one skeleton warrior led seven or eight skeleton soldiers under it, and the skeleton soldiers led by the other skeleton mage fought together, and finally the skeleton mage's strength was slightly inferior, and all the skeleton soldiers under his command were wiped out, and he was hacked to death by the skeleton warrior.

However, the skeleton warrior's side also suffered a lot of losses, breaking a few bones himself, and his younger brother only had three left.

And then the skeleton warrior began to pack up his loot, which was naturally the soul light ball, and for the undead in the underworld, the soul light ball was the most important.

In addition to absorbing the soul light ball of the skeleton mage, the skeleton warrior also absorbed three souls that looked good, while the rest of the light balls produced by the skeleton soldiers, it seemed to be inconspicuous and gave them to the three younger brothers under him.

After absorbing the loot, Qin Wen was surprised to find that this skeleton warrior had undergone a lot of changes even with his younger brother.

The skeleton warrior's bones have become brighter and thicker, and the combat knife in his hand looks sharper, not only that, but on its shoulders, there is even an extra pair of shoulder armor, Qin Wen has no doubt that as long as this skeleton warrior evolves a few more times, he is afraid that he will break away from the identity of the skeleton warrior and become a higher-order skeleton warrior!
