Half a minute later, Song Jian was shocked to find that the huge ancient tree in front of him had not been harmed in the slightest except for some white marks on its surface.

Not to mention the damage, the ancient tree's health bar didn't even appear.

"Damn, what the hell is going on, even if it is a big tree cast of steel, it should be stopped by me before it ......" Song Jian frowned, since he entered the game, he had never encountered such a thing.

"This ancient tree is protected by the power of the rules, and you can't do any damage to it until it changes form......" said the robot Nafiboya with a blank expression as she took two steps forward.

"The power of rules? Is this true of all the ancient trees here? Song Jian slashed towards a big tree on the left, this big tree was obviously much thinner than the one in front of the treasure chest, a pale golden sword qi directly passed through its body, and after a while, the upper half of the big tree made a violent friction sound, and slowly fell to the ground.

"Obviously, you have already found the answer yourself, and the big tree in front of you is quite special......" Nafiboya twisted her neck and looked at Song Jian and said.

"Okay......" Song Jian shrugged his shoulders and walked forward.

Song Jian walked under the tree, the moon spirit wheel beside him was still turning lazily and slowly, and it seemed that the big tree was not threatening and hostile to it now.

First picked up the two pieces of magic silver essence, and then Song Jian walked to the treasure chest, this treasure chest was surrounded by bones, which had been embedded in the depths of the tree roots, and it seemed that the time here was very long.

Song Jian swept away the dust covering the treasure chest, and some special runes were engraved on the lid of the treasure chest, and a hideous grimace with a big mouth was used as a lock, and many white bones were carved around it as decoration, which looked a little weird.

"This is a treasure chest from 1,700 years ago, in the style of the Cansa VII of the Undead Empire, and it may contain some items related to the Undead Empire......" The robot Nafiboya stood in place, her eyes emitting a soft glow, constantly scanning the treasure chest.

"Items from the Empire of the Dead?" Song Jian was a little disappointed in his heart, obviously, with his profession, he probably didn't need the items in it, but he couldn't just give up, Song Jian pressed his hand on the treasure chest, and suddenly there was a "bang" sound in his ears.

System: You have found a locked treasure chest, and you need to unlock it at level 10 or higher to open this treasure chest;

"Locked treasure chests?" Song Jian looked left and right, and didn't see that this treasure chest was locked there, but since the system had already given a prompt message, it was naturally impossible to lie to him.

And generally speaking, the items in a locked chest are obviously more valuable than the items in an unlocked chest.

Song Jian took out the key of forgetting from the package bar, and gently inserted it into the keyhole, and after a while, the key of forgetting turned into the shape of a finger bone, and at the same time, there was a sound of "click" gears turning from the treasure chest.

"Sure enough, this Forgotten Key is simply a master key, which can not only open all kinds of closed doors, but also open locked treasure chests......" A smile appeared on the corner of Song Jian's mouth, and his hand pressed on the treasure chest, and a system progress bar appeared in front of him.

System: Treasure chest is open, opening progress is 1%...... 5%…… 8%……

The opening speed of the treasure chest is not fast, which also means that the grade of this treasure chest is not low, at this moment, the big tree in front of Song Jian, on the thick trunk, suddenly opened a pair of eyes, scarlet eyes stared at Song Jian who was opening the treasure chest, a thick tree root, slowly poked out of the soil, like a poisonous snake, wrapped around Song Jian's ankle.

At the moment when this big tree turned into a dryad, the moon spirit wheel that was slowly swirling around Song Jian suddenly let out a trembling sound.

"Hum~"

Then the moon spirit wheel turned into a white light, leaving an afterimage in the air, and flew towards the dryad, and with a "bang", it slashed into the dryad's torso.

Originally, half of Song Jian's mind was spent on opening the treasure chest, and most of his mind was spent on the weird tree in front of him.

Click~

The Moon Spirit Wheel left a cut mark more than a foot long on the trunk of the big tree, and a fishy red liquid slowly seeped out of the cut, like blood.

The Moon Spirit Wheel didn't need to be controlled by Song Jian at all, and it constantly launched attacks around the dryad, cutting, and the sound of collision was endless.

The roots of the tree wrapped around Song Jian, and the process of opening the treasure chest was forced to be interrupted, Song Jian's heart moved, and the whole person turned into a translucent soul state, and the roots that popped out were entangled in the air, and Song Jian retreated sharply, leaving the attack range of the dryad in an instant.

Bo Bo Bo ~ Countless branches stabbed at Song Jian like javelins, and almost as soon as he left, an arm-thick branch was inserted into the place where he had just stood.

The dirt beneath his feet was also churning, and it seemed that countless invisible giant snakes were surging under the dirt, surrounding him.

Song Jian, who performed the soul walk, was extremely fast, dodging the attack of the dryad, while retreating sharply, and after a while, he withdrew more than ten meters away, and the moon spirit wheel also flew back to Song Jian's side because it was beyond the range of the attack.

Song Jian turned his head to see that the robot Nafiboya had retreated to a distance of thirty meters, tilting his head and looking at him motionlessly.

This dryad's attack range was extremely wide, retreating to seventeen or eighteen meters away, Song Jian was still constantly attacked, until it retreated to thirty meters away, and the roots and branches of the dryad slowly retracted.

"The power of the rules is broken, it's dead!" Song Jian summoned the Sky Breaking Sword and pointed at the dryad thirty meters away and announced loudly.

"This is an eighty-nine-level lord-level boss, with third-order combat power, can kill more than five bosses of the same level and grade at the same time, strong, with a passive effect of 30% long-range damage reduction, and is immune to magic damage below level five, and the weakness is that it can't move,...... "The robot Nafiboya said quietly on the side.

Song Jian found that although she didn't have any attack power and couldn't assist herself in attacking, she had super dodge ability, and when she was attacked by monsters, she wouldn't be a burden to herself, and when she encountered any monster, she could scan and detect the opponent's attributes, and even knew her weaknesses, which showed that it had a powerful monster information database, and as a combat assistant, it was still helpful.

"I said that the moment the power of the rules is broken, it is already dead......" After Song Jian finished speaking, he put on a dashing posture, brandished the Sky Breaking Sword, and shouted in a low voice: "Karmic Fire Red Lotus, Ten Thousand Sword Technique!" ”

In an instant, countless spirit swords appeared around his body, covering a dense area of tens of meters, and then, these spirit swords made a sharp sound of breaking through the air and flew towards the dryad.

At the moment when Song Jian cast the Ten Thousand Sword Technique, the eyes of the robot Nafiboya flashed wildly, processing all kinds of information at an extremely fast speed, and almost entered a state of downtime for a while.

At this time, the Dryad in the distance also let out a low roar, like a wounded beast, a large amount of dirt was thrown up, and countless thick roots, like tentacles, stretched out from under the soil, spreading their teeth and claws around the Dryad's body.

"Whoosh~"

These root tentacles were like long whips, and they slammed towards the spirit swords that flew over, and in an instant, explosions rang out one after another, and the other animals in the jungle fled in horror in the direction away from here.
