Gathered by more than thirty undead knights, the re-formed undead knight was very sharp, he rode a very imposing skeleton war horse, wielded the Fang Tian painting halberd, and shot down the iceberg summoned by the demon of the ice sculpture mask and many ice crystal weapons one after another.

The dark blue demonic flame rose from the skeleton warhorse's body, and spread rapidly, causing the undead knight's armor and Fang Tian's painting halberd to be contaminated with a layer of demonic flame.

The demon in the ice sculpture mask immediately felt very unbalanced in his heart, he never thought that these little guards were so difficult to deal with.

In the next moment, the undead knight drove the skeleton war horse to rush and kill fiercely, smashing Fang Tian's halberd fiercely, with the potential of opening mountains and splitting the ground. Although his tricks were not complicated enough, he had a very original energy, and he suddenly attacked, causing the demon in the ice sculpture mask to be bombarded and retreated a long distance by the bombardment, and he vomited blood.

Lin Feng also rushed here at this moment, and saw that the demon in the ice sculpture mask encountered such a difficult battle, so he didn't make fun of him. Because Lin Feng understood that in such an ancient ruin, it would not be surprising to encounter any mysterious and powerful existence. Fortunately, the demon in the ice sculpture mask encountered these troubles first, which was equivalent to exploring the way ahead, Lin Feng felt very relaxed, so he watched the battle for a long time.

The demon in the ice sculpture mask angrily condensed a huge and heavy ice sword with the cold air around him, and then he also used the fierce sword technique of the head-to-head battle.

When he duel with Lin Feng before, he didn't use this mastery because he felt that Lin Feng's sword path was already very good, and even if he used this sword technique to the fullest, he couldn't pose much threat to Lin Feng.

The Ice War Knife and the Netherworld Heavenly Painting Halberd fought fiercely for more than a dozen moves, and the Undead Knight was finally unable to defeat the demon in the ice sculpture mask and was killed by it. And in a thick nether mist flickering, more than thirty undead knights also condensed and formed. What was slain just now was the summoned thing they had fused.

Although the more than thirty undead knights did not die, they were all injured to a certain extent, and their fighting spirit was also defeated as a result, from the initial calmness to the current panic.

Of course, the demon in the ice sculpture mask could not let them go so easily, and immediately summoned the cold ice qi to freeze them, and then the demon in the ice sculpture mask unceremoniously picked up the ice battle knife. Kill all these frozen undead knights.

The dead undead knight did not leave behind the corpse, but turned into a gray mist, and then a very crisp sound was heard, but it was more than thirty turquoise spars.

"This should be a spar containing origin energy, it's really good, and it can be regarded as the trophy after a fierce battle just now. The demon in the ice mask let out a long breath.

Lin Feng walked over in silence and slightly used his divine sense to probe one of the turquoise crystals, which indeed contained a very rich source energy. In other words, in fact, the more than thirty undead knights before were already dry bones. But because of this spar containing the origin energy, they are like resurrected, and they have a very good combat power.

"Maybe I'll go ahead and collect more of these hedrons, which will bring the corpses of ancient beings back to life. Even if these spars are given to the demon puppets in the Xuanluo Bead Enchantment Space, their strength can be greatly improved. Lin Feng thought to himself.

The sky of this space is still so colorful and glowing with fantastic brilliance.

Next, Lin Feng and the demon in the ice sculpture mask both sped up and explored forward, and sure enough, they encountered such an undead knight not far away. It's just the undead knight who crosses the back. The better its armor defense, the stronger it will be.

Lin Feng tried his best to distance himself from the demon in the ice sculpture mask. It took more than half an hour to kill some undead knights alone, and Lin Feng collected one hundred and thirty emerald crystals and sixty-nine dark kyanites. Among them, the origin energy contained in deep kyanite is more vigorous, more than half of that of turquoise.

After a while, both the Ice Mask Demon and Lin Feng came to the end of the road, and there were three forks in front of them. And before each fork. There is a quaint stone monument standing in the end.

Lin Feng took a closer look at the three stone tablets, but saw that they were engraved with undead knights and a large number of origin energy crystals, a lot of immortal treasure weapons, and the stone tablet on the far right was engraved with a large prison but nothing else, which looked very empty and simple.

It is precisely because of its few strokes. made Lin Feng feel that the place where this third fork in the road led should hide a greater secret.

If there really was only a simple prison, wouldn't Lin Feng be quite a loss?

"I don't know how you choose, senior?" Lin Feng asked with an indifferent smile.

"As long as you have enough strength, you can grab a lot of immortal treasure weapons, and these things are not very obvious for real masters. The demon in the ice sculpture mask sneered, and suddenly the phantom flickered, leaving the first fork in the road.

Obviously, the Demon of the Ice Sculpture Mask thought that he could kill a large number of undead knights there, and collect a large number of Origin Energy Crystals. It was the Origin Energy that had been preserved since the time of the Old Gods, and it was very important for an ancient demon like the Demon of the Ice Sculpture Mask. This energy can not only increase his strength, but also make his lifespan longer.

"I don't care about these energies, after all, I can't completely absorb and refine such origin energy, so it's more reliable to slowly accumulate the power of immortals. Lin Feng said in his heart.

And for the many immortal treasures, Lin Feng didn't particularly care, over the years, Lin Feng had accumulated enough weapons, and in the future battle of the Heaven and Earth Tribulation Guardian, Lin Feng would also be able to collect more immortal treasure weapons.

From the beginning of coming to this enchantment space, Lin Feng didn't care too much about what he could gain, he just felt that adding some experience and exploring the mysteries of the ancient sages who left this enchantment would be very helpful for the future battle of protection.

"Then take the fork on the far right, although it seems that there is only a very rudimentary prison engraved on the stone tablet, but my intuition is that there is a great mystery hidden in it. Compared to the fact that I can learn more about the era of the old gods, it makes sense to come here to explore. Lin Feng analyzed in his heart.

What's more, if you want to collect energy or immortal treasure weapons, there are still opportunities in other places, and to explore the mysteries of this place, you really have to choose the fork in the road on the far right.

Lin Feng has always been a very decisive person, and after thinking about it, he leaped to the rightmost road, operated the Wu Clan's Golden Body Xuangong, and carefully defended forward. (To be continued.) )
