Everyone in this team of warriors was speculating about the origin of the entrance to this underground ancient city, and after some deliberation, everyone agreed with Sima's ruthless opinion.

That is to say, the stone chamber cave in the desert castle behind should have been excavated by the warriors who were explored later, or the zombies who became powerful, otherwise if the natives of the ancient city found a way to escape, there would not be so many zombies in the ancient city.

"I'm now more and more sure that this is an ancient dungeon, and that's the dangerous place your grandfather arrived with the expedition team. Duan Yu smiled lightly.

"However, Brother Duan, what you said made me even more worried, back then, my grandfather and those warriors were killed and injured because of the birth of the fire phoenix, and even if he was lucky enough to escape, he no longer had the courage to explore after he came back, and he had to spend the rest of his life in seclusion. Sima ruthlessly looked at the distance, remembered many past events, and sighed deeply.

A bleak cold wind blew, I really don't know why such an underground ancient city still has the formation of wind, maybe it is just like the ancient tomb of the real martial arts swordsman.

Moreover, in the cold wind, there is a strong smell of decay and destruction, in essence, the underground ancient city is not the same as the ancient tomb?

How many creatures were buried in this land a long time ago? When the destruction came, it was a wordless mourning. Perhaps it is a relief to die with a whimper, but the most tragic thing is the indigenous people who formed zombies after death because of the gloomy environment and resentment.

If at some point they can regain some of their former consciousness and learn of their current situation, they will probably be furious.

There is no need for torches now. Although the underground ancient city is eternal, there is no sunlight shining and the brilliance of the stars. Fortunately, there were countless emerald and silver-white fireflies floating in the void.

The light they emit is not bright, but it gathers into a tower of sand. When the armpits are gathered, the light of all the fireflies gathers and lights up the entire ancient city.

Duan Yu even felt that this kind of light was quite beautiful, just like the aurora he had seen in that world before he crossed over.

The unique fireflies in the void will not cause any attack on people at all, and when people walk by, they will spread around, so that the area in front of them becomes brighter and brighter, which is a very powerful way of lighting.

Due to the previous discussion, Duan Yu and his teammates had already decided to go to the City Lord's Mansion to have a look first. If the most valuable things in the ancient city would be placed there, it should undoubtedly be in the city lord's mansion in this underground ancient city.

On the way, you will encounter a few scattered zombies from time to time, which are easy to deal with and can be slashed with a quick sword.

The most difficult thing is actually those strange demon beasts, which are different from the outside world, the original very ordinary demon beasts and beasts, due to the underground ancient city, due to the special environment and some other factors have mutated. Quite awesome.

Some of them are zombie-like undead creatures, and some are monster beasts that have been mutated and reproduced, all of which are several times more powerful than their ancestors.

Everyone wanted to save some internal force, but now they have to use their strong internal force to fight bravely. If you are injured by these undead demon beasts, it will be quite a troublesome thing.

Because not everyone in this martial arts team has an invincible body like Duan Yu, and Duan Yu doesn't have so much blood to use as an antidote to so many people. So you can't be careless, sometimes a small mistake. It is possible to cause great disasters and make people regret it.

At this time. Among the group of undead demon beasts that Duan Yu and the others encountered, a purple-scaled python and a two-headed flying tiger were the most difficult.

The other demon beasts are also very good, so they are dealt with by the silver armor guards, and the two-headed flying tiger really responds to the idiom of "like a tiger with wings", and it is rare to find a tiger demon beast with wings.

Its size is huge, three times that of ordinary tigers, in addition to its sharp claws, the two heads of the two-headed flying tiger are also quite powerful, and the single horn on the forehead is comparable to a weapon of the lower grade of the spirit level.

Most of the weapons of the people present were difficult to resist its attack, which was why Duan Yu ordered the most powerful people to deal with the two-headed flying tiger.

The two-headed flying tiger's special move is not just a simple attack, but the left head can send out fireballs, and a deep pit appears on the ground when it is hit, and the flames can even burn stones for a while;

Long Teng, the elder of the Ancient Sword Blood Alliance, didn't pay attention to it slightly, and he received a Xuan Ice arrow in the shoulder, which was pierced on the wall of a stone house. He struggled to break free on his own, and felt the Xuan Ice energy spread out in the meridians, and a layer of frost suddenly appeared on his face.

No one has time to save him, and they are all doing their best to fight against the undead demon beasts.

In other words, Sima Ruthless, Ouyang Invincible, and Sword Maniac are already two silver-armored guard commanders in the late stage of the Innate Jindan Realm, and these five masters are teaming up to deal with the two-headed Flying Tiger.

As for the other quite powerful undead demon beast, the Purple Scale Python was dealt with by Duan Yu alone.

Duan Yu's strength, others may not know how, but he knows that he once had a lot of experience fighting against undead demon beasts in the True Martial Sword Warrior Ancient Tomb, and he can fight ten at a time, even if it is a powerful undead demon beast, Duan Yu has no fear at all.

At first, this purple-scaled python only swept with its snake tail, and pounced on Duan Yu in an attempt to entangle Duan Yu, once it was entangled, of course, it would lead the decisive battle.

From time to time, it would also attack with a bloody mouth, and Duan Yu used the wonderful situation of the Wind Trick to dodge smartly and quickly.

There's no need to compete with what the enemy is best at, it's the wisest choice to play to your strengths and avoid your weaknesses!

The attack of the python is "a sweep, a winding, a bite", any move hit, its power is quite large, there is no fancy trick at all.

There was a constant sound of air explosions in the air, and Duan Yu dodged many times, causing most of the Purple Scale Python's attacks to miss. The anaconda tail full of explosive power swept across the ancient stone house, and suddenly a thick stone wall collapsed, and then the tail pumped to the ground, cracking deep cracks, like a spider's web extending around.

Occasionally, Duan Yu used the Demon Breaking Sword to fight against the tail of the Purple Scale Python, not to win in a hurry, but to test how powerful the Purple Scale Python really was.

Duan Yu knew that he couldn't just dodge, that would only lead to more and more passivity, and he had to be targeted and look for opportunities to fight back.

He has never been a person who sits still, and when he encounters any serious problem, he is able to maintain a calm mind and a wise mind to observe and analyze.

"Hmph, bold demon, your tricks have been exhausted, it's time for me to make a move!" Duan Yu shouted, his voice not only contained a strong internal force, but also an awe-inspiring righteousness.

The purple-scaled python was caught off guard, and had never encountered such an attack, and suddenly his mind was briefly dizzy.

Duan Yu flickered decisively, and he was not afraid of being entangled by the huge python, holding the Demon Breaking Sword in both hands, slashing horizontally and vertically. At this time, any fancy and complicated tricks seem redundant, unlike the battle between large demon beasts and the battle between warriors, not caring about the subtlety of the tricks, but the actual power of the tricks.

Five swords slashed out in a row, and Duan Yu did his best.

Although it is said that it is five swords, the speed and momentum are as fast as if only one sword was used, and it can be done in one go!

Without giving the purple scaled python any time to react, in this short period of vertigo, the huge snake head of the purple scaly python was cut off, and the bulky headless python's body fell to the ground with a heavy sound.

Suddenly, the huge snake head stared at Duan Yu angrily, emitting two red rays of light, like dark red blood condensed.

If it is an ordinary martial artist, after killing a powerful demon beast, he will inevitably be a little proud, and it will be difficult to take care of his own defense.

Fortunately, he was Duan Yu, not anyone else, Duan Yu was enough to dodge the sneak attack of these two weird red rays of light by instinct, but when he saw that the two demon beasts behind him were hit by this red light, he immediately fell to the ground with a scream, and immediately turned into a pool of blood, which was quite miserable.

The python's head had not yet stopped, but it still flew over, opened its bloody mouth, and launched a final attack like a mad dog.

"The Blade of the Dragon Slashing Sword!" Duan Yu shouted, holding the demonic Demon Breaking Sword in both hands, and slashed out.

In an instant, the head of the crazy python was split apart and fell into the dust on the ground.

"Very good, it is really appropriate to slash demon beasts with a magic sword. Duan Yu smiled heartily, and no longer stopped the Demon Breaking Sword from absorbing the contaminated python demon blood.

In an instant, there was no blood stain on the Demon Breaking Sword, and Duan Yu didn't have time to let the Demon Breaking Sword absorb the blood of the purple scale python's corpse, but immediately flashed over to help Sima Ruthless and them deal with the two-headed flying tiger.

Although the two-headed Flying Tiger's fireball technique and Xuanbing Condensing Arrow were very good, under the siege of so many masters led by Duan Yu, only the tragic one was killed.

And the other demon beasts were also killed by the silver-armored guards led by Zhao Yanling, and the strength of those silver-armored guards was indeed good, but it was a pity that they couldn't be alone. At this time, Duan Yu walked over and took out the inner pill of the purple-scaled python, which contained a strong spiritual power.

Even if you don't use this demon python Neidan, you can sell a lot of blood crystals when you go back in the future, it is a trophy, you can't do without it.

As for the Two-Headed Flying Tiger's Neidan, Sima ruthlessly took it and gave it to Duan Yu, but he decisively waved his hand and refused, saying, "You all put in a lot of effort to kill this Two-Headed Flying Tiger, you go and discuss how to distribute it." ”

Everyone was quite moved, and their admiration for Duan Yu became a little deeper.

After some discussion, Sima ruthlessly handed over the two-headed Flying Tiger's Inner Dan to Zhao Yanling, saying that after leaving the underground ancient city, it would be more reasonable to distribute it according to the merits.

After all, they were besieging the two-headed flying tiger just now, and it was really difficult to estimate who contributed the most. (To be continued......)
