Luo Feng really didn't deliberately go to the Normal World Realm to provoke those two people, but the characteristics of the Palace of the Dead determined that if he wanted to leave the Palace of the Dead, he could only return to the Normal World Realm first. As for the fact that those two people would be half angry with him, and regard this coming and going as a mockery and insult, of course Luo Feng didn't care.

It's just that now, he doesn't want to fight with the other party for the time being.

Now that he has been promoted to the tenth level trainee magician, the most important thing at the moment is naturally to maximize his combat power first, and when that time comes, I believe that he will definitely be able to retreat under the attack of those two people.

Luo Feng's existing undead minions, the Skeleton Horse Emperor whose highest level is an eighth-level undead creature, are only one, which is of course not enough.

With Luo Feng's current combat power, there will definitely be no problem in enslaving a level 10 undead creature, what is missing is just a target.

Luo Feng was on the undead plane, holding the book "Encyclopedia of Undead Creatures" in his hand, and was looking for it carefully.

After looking for a long time, there was no more suitable target, Luo Feng closed the book and threw it aside. In fact, Luo Feng almost memorized this book backwards, he had basically determined the goal, but he was afraid that something would be missed, so he looked it up again.

At this stage, the undead creatures that are suitable for Luo Feng to fight and retreat at the same time, and have speed, mobility and combat effectiveness at the same time, are always bat ghosts.

The level of the seventh-level undead bat ghost is a little worse, but as a swarm undead creature, it is inevitable to produce an undead king, and the eighth-level undead bat ghost king is an excellent goal. If you are lucky enough to find that Bat Ghost Emperor, it will undoubtedly be Luo Feng's biggest hole card.

The Undead Emperor is two levels higher than the Undead King.

Therefore, the Bat Ghost Emperor is a tenth-level undead creature, which happens to be at the same level as Luo Feng, and it is completely Luo Feng's only goal to maximize his combat effectiveness.

Of course, Luo Feng dared to think like this, also because he knew enough about bat ghosts.

By the size of the cave, he could accurately deduce the size of the bat ghost group, as long as he conquered the large bat ghost group, the bat ghost king would inevitably have it, and if there was really a bat ghost emperor, it must be in the largest of all the caves.

In this way, the scope of Luo Feng's search has narrowed down a lot.

Although the result will be a matter of luck.

Luo Feng stretched his waist, his bones crackled, and he turned into a witch body in the blink of an eye. He summoned the Skeleton Horse Emperor and ordered all the batghost servants to follow, running towards the Shanyin leyline with all his might.

The speed of the Skeleton Horse Emperor was indeed fast, and just a moment later, Luo Feng came to the territory of the bat ghost, in the leylines of Shanyin.

Luo Feng went around in circles as before, searching for the target, but he was looking for the smallest Sanyin Cave before, but now he was looking for the largest Sanyin Cave.

Although the Shanyin Leyline covers an extremely wide area, with the speed of the Skeleton Horse Emperor, there will still be enough time for Luo Feng to search the entire mountain range.

After going around in a circle, Luo Feng set three goals.

Three huge black holes that are extremely large and difficult to distinguish!

The three openings were about twenty meters high and nearly thirty meters wide, and the caves were dark and quiet. Based on Luo Feng's experience, the number of bat ghosts in these three Shanyin caves is at least 10,000! If the caves are deep enough, then it is very likely to hold 20,000 to 30,000 bat ghosts.

The entire Shanyin Leyline, this is already the largest of the three Shanyin Caves, and the three bat ghost groups inside must also be the three largest groups in the entire Bat Ghost Territory. There will definitely be a Bat Ghost King, and if the Bat Ghost Emperor really exists, there is a chance that it will be in these three Shanyin Caves.

The three holes of the target are so similar in size that they are almost indistinguishable.

Luo Feng picked one at random, and stood in front of the huge hole, a little hesitant.

To be honest, the sheer size of the bat ghost swarm also scared him. Luo Feng thought at the beginning that the largest group of bat ghosts was only five or six thousand, but after a careful search, Lu Dao found that there were too many caves in Shanyin that could accommodate thousands of them, and the three largest caves were obviously tens of thousands.

The gap between thousands of bat ghosts and tens of thousands of bat ghosts is huge.

Although the bat ghost is only a seventh-level undead creature, and the combat power of Luo Feng's tenth-level apprentice is obviously much higher, but the number of tens of thousands is probably enough to exhaust Luo Feng to death on the spot! And Luo Feng's undead servants are even more unbearable, there is no one who can help, and there is only a non-combat type skeleton horse emperor who is more advanced than the bat ghost.

In other words, this war of the undead can only be fought by Luo Feng himself!

Luo Feng ambushed the Skeleton Horse Emperor and a group of batghost servants at the entrance of the cave, if he really couldn't resist, he could respond at any time, lest he really be surrounded and killed in the cave.

Before going through the actual battle, Luo Feng still reserved a cautious attitude towards the combat power of his witch body.

So in this battle, he has to go all out!

The undead magic in the body worked at high speed, passed through the heart, turned into flesh and blood, and turned into a strange melee energy. A layer of gray red oozed from Luo Feng's body, draped over his body like a cloak, the breeze blew, and the red light flew with the wind but tightly wrapped around Luo Feng's body.

At this time, Luo Feng's body was like a machine, and the undead magic in his body was the energy that supported his operation.

In the dark, Luo Feng's golden eyes shone even brighter, like a pair of dazzling night pearls.

Luo Feng smiled slightly, the cave in the mountain where the bat ghost lived couldn't see his five fingers, the last time it was so dark made him suffer, and now that he has assimilated a bat ghost, Luo Feng has also inherited the ability of the bat ghost's night vision.

The pitch-black cave could no longer restrain his gaze.

Luo Feng stood at the entrance of the cave, his eyes pierced through the darkness, and the specific situation in the cave was undoubted.

Sure enough, as he expected, there was an extremely large group of bat ghosts in front of him.

The cave is bottomless, and the bat ghosts hang upside down on the walls and ceilings of the cave, and the place near the entrance of the cave is relatively large, and the further inside, the denser the bat ghosts become.

The bat ghost group conquered by Luo Feng before was relatively shallow, and the deepest was only about a few tens of meters. And the one in front of him can't see the bottom at a glance, with Luo Feng's eyesight at this time, it can be seen that the hole here is deep.

The deeper the cave in Shanyin, the more the number of this bat ghost group is, and it seems that the number estimated by Luo Feng before is still a bit small.

The matter has come to this point, and Luo Feng cannot be allowed to retreat.

Luo Feng suddenly roared, and the sound waves were like thunder, and he rushed into the cave in the mountain yin.

The bat ghosts in the cave were all shocked, and under the oppression of Luo Feng's strong momentum, the bat ghosts flapped their wings uneasily and chirped.

Luo Feng ignored it, and stood outside the entrance of the cave in a demonstrative manner, the roar was louder, and the hole was full of Luo Feng's arrogant echoes.

If the bat ghost was weaker, I am afraid that he would be stunned by such a loud noise!

At this moment, a scream came from the deepest part of the cave, and the voice was sharp, and it came out clearly in Luo Feng's strong roar.

This is a response to Luo Feng's provocation!

Luo Feng was not surprised, and with a fierce force under his feet, he quickly rushed into the cave in the mountain yin towards that voice.
