Xia Yu quietly watched the skeleton warrior complete the changes.

The skeleton warrior who absorbed the soul flames became thicker and even produced a faint jade light. The bone knife in his hand looked sharper. Not only that, there was even more bone armor on his body. As for its little skeleton brothers, the soul flame also grew stronger.

In the new soul prison in the underworld, the strength of the soul flame determines their level. Monsters with low level levels are completely incomparable to monsters with high level levels. The former can only become a vassal of the latter, or even food. Only existences of the same level will break out of war and further enrich their soul power.

Xia Yu touched it and launched a raid on the small team.

In fact, when Damu saw a soul flame appearing just now, he was ready to move. It was Xia Yu who forced it to stay in place, so it did not pounce on it to grab food.

It took less time to destroy this newly won skeleton team. Big Mouth once again gained a lot of soul flames, and its body also expanded!

After moving forward not long ago, the monster in front of Xia Yu underwent earth-shaking changes.

Xia Yu could feel that the monsters in the New Soul Prison in the Underworld had relatively strict territory divisions. The first place he appeared was obviously owned by the skeleton monsters. Now that he has stepped into the zombie territory, the monsters he encountered are all zombies.

The blue-black zombie has a complete body. The one with a slightly higher level is the pure black iron corpse. This is an existence of the same level as the skeleton warrior, and the one with higher strength is the bright yellow copper corpse.

Like skeleton monsters, these zombie monsters also have two clusters of soul flames in their eye sockets.

Xia Yu killed all the way and soon encountered a large-scale zombie legion.

The leading zombie is a death knight riding a headless war horse and wearing silver-gray armor. It has more than 200 little brothers under its command. In addition to the largest number of ordinary zombies, there are ten iron corpses of higher level and three bronze corpses.

These monsters made of corpses are different from skeletons. Their defense power is greatly improved, mainly physical attacks, and their movements are not so flexible. However, their soul flames are very powerful, especially those boss-level iron corpses and copper corpses. The soul flames of the Death Knight are even more powerful. They are the most powerful monsters that Xia Yu has ever seen after entering the New Soul Prison in the Underworld.

Faced with many monsters, Xia Yu used his new tactics to launch an attack.

Xia Yu used the stealth ability of Big Mouth to wander among the monster group, specifically looking for monsters of the level of iron corpses and copper corpses, and then used a punch mystery to bombard them.

The invisible ability of Big Mouth is only about two minutes, and beyond this time limit, it will be particularly weak. But what is amazing is that as long as it absorbs the soul flame, it will immediately feel like it has taken a big tonic pill, which can make Xia Yu enter an invisible state again!

In such a cycle, Xia Yu quickly killed all the leaders-level monsters, and those little brothers also fell in large numbers under the attack of the silver-winged unicorn worm.

The Death Knight has a headless war horse and moves fast enough, but he is reused by Xia Yu's old trick. He uses the stealth ability of the big mouth to attack the approaching body, and then is bombarded by Xia Yu's continuous punches!

The big mouth continued to replenish the surrounding soul flames, allowing Xia Yu to continue to enter an invisible state.

With the absolute stealth ability of Big Mouth, Xia Yu can be said to be like a tiger with a great increase in combat power.

The Death Knight is actually very strong, but when encountering an opponent like Xia Yu, you can only get beaten.

In the end, the Death Knight died unjustly, and the remaining zombies were left as if they were amnesty after the Death Knight died.

Xia Yu was too lazy to chase the minions and watched them leave.

Calmness is restored around.

The big mouth began to devour the soul flames of the Death Knight as big as a fist.

In an instant, the big mouth suddenly swelled, reaching nearly fifty centimeters in length, about the thickness of an adult's arms, and a pair of dark eyes grew, which looked more and more vivid.

"This new soul prison in the underworld looks like a blessed land with big mouths!" Xia Yu thought and continued to move forward. Soon, Xia Yu saw another zombie legion.

The zombie legion in front of me was stronger than the one I encountered last time, because Xia Yu saw that there were more powerful leaders under the Death Knight, twenty iron corpses, and an astonishing ten copper corpses! In the battle just now, Xia Yu had fully realized the difficulty of copper corpses. At this time, he was indeed a little scared to see ten copper corpses at once.

The most terrifying thing is the leading Death Knight. Judging from the body size of the Death Knight and the seated battle rider, it is much stronger than the Death Knight just now. Obviously, it is an old-fashioned strong man who has been a Death Knight for a long time, and it is naturally incomparable to the evolved guys.

The number of this monster legion has reached an astonishingly more than 400.

This is a hard battle.

At the beginning of the battle, Xia Yu still used the tactics just now to launch a raid on the zombie unit.

Xia Yu fought against more than 400 monsters with silver-winged one-horned insects and big mouths.

Fortunately, this zombie legion is obviously a nearby overlord level, and there are no large zombie legion around, which also gives Xia Yu enough combat space. Otherwise, if there are several other zombie legion around, his battle will definitely be extremely hard.

Xia Yu used his stealth ability to engage in guerrilla warfare with this zombie unit. As time goes by, he cleaned up all the boss-level monsters again.

Then, Xia Yu used his old trick again, using the stealth ability of Big Mouth to launch a sneak attack, and finally killed the Death Knight.

This time, Xia Yu also clearly felt the strength of Big Mouth. Its time for each invisibility was obviously longer than before!

This time, there are many remaining zombie legions, but once they lose their leader, they will scatter again.

When the Death Knight died, Big Mouth could not wait to step forward and swallow its soul flame. This time the great tonic made Big Mouth's body shine and its body shape suddenly increase, becoming as thick as a calf.

The big mouth, which had a huge body, finally looked like a war beast, but its appearance was a bit funny and looked like a large silkworm baby.

As the body size soared, Xia Yu's consciousness communication with Dazui became clearer.

At this moment, Dazui sent another message to Xia Yu that he wanted to eat the soul flame.

The big mouth is like never having enough food. Even if you swallow the surging soul flames of two death knights, you are still so hungry! This is like a foodie, entering a huge world built entirely of food.

The foodie's spring is here!
