Three days later, Wu Hao and his entourage arrived at the Elven Forest, which was lush with foliage and full of nature and life, before sunset.

When you look up, you can see the huge ancient tree that seems to support the sky.

The branches and foliage of the ancient trees were luxuriant, as full of vitality as Wu Hao had seen when he looked at the top of the Black Dragon Mountain Range a few days ago, but at this moment, looking up from below, he saw that many branches were hanging down weakly.

He looked closely, and saw that the emerald green was mixed with scattered withered yellow colors, as dazzling as silver hair emerging from a black hair.

Underneath the ancient tree, a hemispherical transparent energy shield emitting a faint green glow could be seen.

That's what Natalia calls the realm of nature.

"The scope of the natural realm has shrunk again."

There was a hint of sadness in Natalia's eyes.

Unlike the Dawning Realm, the Natural Realm of the Sacred Tree of Life is a shield-type realm, keeping dark creatures out of it.

Guided by the will of the Sacred Tree of Life, the power of the elves can pass through the natural realm to attack dark creatures outside the realm, but attacks from dark creatures will be blocked by the realm.

The existence of the natural realm avoids the casualties of the elves, but the disadvantages of this realm are also obvious, and the dark legions can consume the power of the sacred tree of life little by little by attacking the natural realm.

Originally, this kind of war of attrition could not have worked on the Sacred Tree of Life, and at the level of the Sacred Tree of Life, the speed of power recovery far exceeded the attrition caused by the Dark Legion's onslaught on the natural realm.

However, with the fall of the power level of the Sacred Tree of Life, as well as the decrease in the concentration of Xuan Qi between Heaven and Earth, the speed of the energy absorbed by the Sacred Tree from Heaven and Earth further decreased significantly.

It was the Dark Legion that discovered this, and attempted to consume the Sacred Tree of Life through a war of attrition.

It has only been a short week since Natalia broke through the siege, and the natural realm has shrunk in a large circle, which means that there is not much power left of the sacred tree of life.

I'm afraid that in a few days, the sacred tree of life will truly fall.

She quickly controlled her emotions, they had already brought the fragments of the Holy Sword of Light, as long as the elven warriors of the Radiant level opened the Dawn Realm, the elven warriors would definitely be able to repel the two dark legions.

The Fire Phoenix let out a low cry of uneasiness, carrying the four of them and continuing to fly towards the Sacred Tree of Life.

Although the main force of the Dark Army is besieging the natural realm, there should still be sentries of the Dark Army hidden in the Elven Forest.

With this in mind, Russell cast a wood-based spell called [Forest Camouflage], and the fiery red feathers of the fire phoenix suddenly turned emerald green, and adjusted its color according to the changes in the surrounding vegetation and light.

Luckily or for some other reason, they never encountered a single dark creature along the way, and they approached the natural realm with great ease.

The four of them stood on the back of the fire phoenix and looked ahead, and an empty scorched black earth appeared at the edge of the woods.

Seen from above, the charred black earth was centered on the Sacred Tree of Life, showing a distinct circular ripple, the traces of the natural realm as it continued to shrink under the constant onslaught of dark creatures.

And on the outer side of the natural realm, the dark creatures are like ants that have found food, forming an impermeable encirclement.

Of course, this kind of encirclement can't stop the king who has the ability to fly, but if an elf king wants to break through from the sky, he will inevitably be surrounded and intercepted by dark creatures above the king level.

Natalia and the others tried to break through the sky, but they were intercepted by the royal dark creatures, but thanks to her mother, the elven queen Elena, they were rescued in time.

The dark creatures of the Dark Legion are not as irrational, crazy and chaotic as the demonic beasts they encountered on the road that were infected by the dark aura, on the contrary, they are very disciplined and orderly.

The Ghost Rock Legion with the earth's mystical aura fended off attacks from the elves in front with a thick rock shield, while the Black Flame Legion with the aura of fire unleashed a variety of fire-attribute magic skills in the rear.

Flames of various shapes flew out, some of which were blocked by the elves' arrows and wood magic, while most of them landed precisely on the natural realm.

In fact, with the sheer size of the natural realm, as long as you are not so unlucky enough to be blocked by the attacks of the elves, you can attack the natural realm even with your eyes closed.

At this time, the sun was setting, and the sky was gradually covered with darkness, and the attack frequency and intensity of the two dark legions increased significantly.

Flames flew out, exploding like fireworks in the natural realm.

But such a fire, to the elves, is tantamount to the fire of death from purgatory, burning life and hope.

As the light dimmed, Wu Hao noticed that near the edge of the natural realm, there were pale green clusters of light, and with the help of the pupil technique, he saw that they were wooden round platforms with a strong wood elemental atmosphere.

"What's that?"

When Wu Hao asked, there were a large number of elves surrounding the edge of the wooden round platform, and instead of attacking the dark creatures that were close at hand, they looked nervous, as if they were waiting for something.

At the same time, some elves were busy building a new round platform in the rear.

Natalia also saw the movements of the elves, her expression was low, and her tone was low: "That is the natural altar, after the power level of the sacred tree has fallen, it is no longer possible to expand the natural realm to areas outside the main body, only with the help of the natural altar, the sacred tree can maintain the huge natural realm." ”

But now that the elves have retreated the Altar of Nature, it means that the natural realm will shrink further, and it also means that the power of the Sacred Tree of Life has been weakened by half.

As if to verify Wu Yu's momentary thoughts, the hemispherical green light quickly dimmed.

The elves guarding the edge of the natural realm quickly dismantled the natural altar and ran for their lives with the materials to build the altar to the reformed natural realm behind them.

At the same time, two armies of darkness rushed up.

Sharp rock spikes emerged one after another, like ghost claws from hell, piercing through elves that could not be dodged.

The flames in the sky flew like arrows, turning the blue grass that was originally protected by the natural realm into a sea of purgatory.

The Dark Legion didn't just blindly use magic skills, when the elves dodged the magic attack, a large number of dark orcs, magical beasts, and even dark elves quickly rushed over, and the elves who could not escape into the natural realm in the future were torn to pieces.

The elves of the natural realm frantically launched a counterattack to stop the attack of the dark army, so that more companions could escape into the natural realm.

In just a short moment, the re-condensed natural realm was completely filled with blood and flames.
