Qi Lin made a cursory visual inspection, and the claw of the tree, which was nearly half a meter long, could easily pierce itself if it was used to stab; And if it is used to grab, then as long as it is accidentally caught, judging from the huge strength of the Tree Demon, it should not be much difficult to tear apart his own flesh.

The situation has obviously become more tricky, and the two nodules can only be used as hammers at best, but now that they have been reborn into a pair of giant claws, the risk of melee combat has far more than doubled.

Qi Lin took off the SCAR-H heavy assault rifle he was carrying behind his back, held the gun in one hand in his right hand, clamped the butt of the gun under his armpit, changed the magazine with his left hand, and kept pouring bullets on the monster's body while running around the alienated tree demon.

In fully automatic mode, in just ten seconds, Qi Lin emptied all the ninety 7.62mm bullets in the three magazines, however, judging from the prompts of the main brain system, none of the shots reached double digits, most of these bullets were stuck in the tough bark of the alienated tree demon, and the few bullets that penetrated the bark basically exhausted all the kinetic energy, and they were unable to cause more damage to the part under the bark.

The bullet did nothing, but it succeeded in angering the tree demon, and after a while, a vine several meters long shot out at Qi Lin's chest, and at the same time, four or five finger-thick roots drilled out of the ground under Qi Lin's feet, wanting to concoct it like the first attack, but this time, it was dodged by Qi Lin, who had an extra heart.

"It is impossible not to have weaknesses...... This shouldn't be the normal defense of E-class creatures...... Even in the Black Forest, in the midst of its home turf, it shouldn't be ...... There must be a weakness......"

The space for Qi Lin to move and dodge became smaller and smaller under the persecution of the alien tree demon, and as soon as he approached the edge of the clearing, those branches and vines would immediately stretch out and dance wildly like the hands of countless demons in hell, trying to grab him and tear him apart.

The powerful tree demon on the opposite side and the ground were not the roots that were drilled out, Qi Lin had no time to care about those branches that were relatively less threatening, and it didn't take long for the clothes on his body to turn into a cloth suit, and there were a lot of shocking scars on his body, leaving only a backpack made of Kevlar fiber material that was barely intact.

"Boom!"

The Tree Demon took a step forward, and the huge claws swept sideways towards Qi Lin, who had to crouch down, but immediately more roots wrapped around his feet and legs.

Tearing off these tendrils with his hands, whose tenacity was no longer much different from metal, Qi Lin rolled to the right, dodging the whipping of the tree demon vines, and then, taking advantage of this gap in attack, he suddenly increased his speed, clinging to the tree demon's body, and drilled under the opponent's armpit.

"Weakness...... Where exactly is the weakness......"

Qi Lin looked at the serrated dagger in his hand, just now when he was passing by the alienated tree demon, he cut a long cut on the other party's waist, but at this moment, according to the blade of the dagger, it was covered with a layer of blue-black hard substance) Once this bitumen-like secretion dries, it looks like opaque pine resin amber, but compared to amber, the hardness of the two is completely one heaven and one earth.

"Weakness...... Mother Spider ...... Dao...... Dryad ...... Dryad ...... Mouth! ”

Qi Lin's eyes suddenly lit up, since he couldn't break through the outside defenses, then he directly sent the bullet to the other party's body, just like he did in the spider mother's lair!

Pulling out the shotgun inserted in the side of the backpack, this is a Winchester M1887 with a sawn one-third of the barrel, Qi Lin grabbed the shotgun in his right hand, and wiped his left hand from the ammunition belt wrapped around his waist, and quickly grabbed a 000 deer bullet, while dodging the attack of vines, roots and giant claws, he quickly filled a round of ammunition into Winchester's chamber.

The six deer bullets were all loaded, and in the face of the alienated tree demon approaching step by step, Qi Lin did not retreat this time, but advanced, and suddenly jumped up, inserted the fingers of his left hand into the gap in the bark of the tree demon, and held Winchester high with his right hand, and stabbed hard into the hole of the tree demon like a mouth.

"Bang!"

"Bang!"

Qi Lin only had time to pull the bolt lever once, and after blasting two No. 000 deer bullets into it, the barrel of the stainless steel gun was flattened by the tree demon's slammed mouth, and if Qi Lin pulled the trigger again, the whole gun would be directly exploded.

Two 000-gauge deer bullets, each with 8-10 rounds of 9.14 mm diameter projectiles, are enough to blow a rhinoceros's head to pieces at close range!

Releasing the shotgun that had been scrapped in his right hand, Qi Lin kicked the alienated tree demon's body, and a backflip widened the distance between him and the tree demon.

"Succeeded??"

As soon as Qi Lin landed, he was immediately ready to dodge the Tree Demon's counterattack, but at this time, the Tree Demon, who had been chasing Qi Lin before, froze in place.

"You killed the E-class mutant creature [Alien Tree Demon] and gained 0 experience points."

"Dead? How inexperienced? ”

Although Qi Lin was a little puzzled by the zero experience value of killing the Tree Demon, the kill information was indeed real, and the mastermind would never cheat people in this regard.

Qi Lin's heart was relieved, and he cautiously approached a little distance, only to see that the vines on the tree demon seemed to have withered and shriveled rapidly, and under the cracks in the hard bark, the blue-black juice began to slowly overflow.

"It looks like he's really dead, and I don't know what those two shots hit......"

Qi Lin kicked heavily on the Tree Demon's body, and the bark that was originally as hard as an armor plate turned out to be extremely fragile, and pieces of it cracked and peeled off, revealing the true body of the Tree Demon.

Only then did Qi Lin notice that the internal tissue of the Tree Demon's body was made of something between flesh and wood fibers, and in addition to the blue-black viscous juice that flowed out of the wound, there was also a pale yellow oily substance, exuding a faint fishy smell.

"Cooper, you say, was this guy really a tree before?"

Qi Lin poked the inner torso exposed by the tree demon with a dagger, and the tip of the dagger easily pierced into the soft tissue, at this time, the blue-black juice that flowed out had lost its effect of protecting the wound, and the viscosity was greatly reduced.

Taking advantage of the fact that the surrounding Black Forest had not yet been surrounded, Qi Lin simply made a cameo appearance as a surgeon, and dissected the trunk of the tree demon with the dagger in his hand little by little.

If this Black Forest really has a "heart", the structure of that "heart" may be close to this alien tree demon, and if you can understand the weakness of the tree demon, you will naturally grasp the weakness of the "heart".

Cutting open a layer of tissue like rotten cotton wool, Qi Lin found that in the body of the tree demon, there were medullary canals the thickness of a little thumb, and all that flowed in the medullary canal were the yellowish fishy liquid.

The smell of this liquid is a bit like a fruit called durian in the old days, but when it is different from durian, the smell is not only unbearable, but it will make you feel dizzy when you smell too much.

Qi Lin covered his mouth and nose after realizing that something was wrong for the first time, and then the dagger cut all the way down the medullary canal, until the blade touched the projectile in a 000 deer bullet, making a metal collision sound.

The shrapnel broke the medullary canal in the Dryad's body...... So these medullary canals should be arteries? That yellowish liquid is blood? Qi Lin muttered to himself as he flipped the tissues in the tree demon's body with the tip of his dagger.

The structure of the Tree Demon's body is really like a tree, except for the bark, phloem and xylem, the innermost part is the center composed of a large number of medullary canals, and other than that, there are no organs, and Qi Lin's shot just now just happened to break a large number of medullary canals located in the center of the Tree Demon.

"Tick."

Qi Lin was still studying the structure of the tree demon, a drop of viscous blue-black liquid suddenly dripped in front of him, Qi Lin subconsciously poked it with the tip of the dagger, but found that the blue-black liquid had become very hard, just sealing the fracture of a medullary canal.

“！？”

A bad premonition came to his heart, Qi Lin jumped up suddenly, and retreated seven or eight steps away - at this distance, he saw that the lower half of the tree demon's body grew many roots of different thicknesses, which pierced into the ground one after another, and streams of unknown liquid were being sucked into the tree demon's body along the pulse of the roots-not only did the wound continue to secrete blue-black self-healing liquid, but even the vines that were already dead attached to the tree demon's body gradually began to show signs of recovery......

“…… Cheat...... Corpse?! Looking at the huge incision that had just been cut by himself, which was completely covered by the blue-black liquid almost instantly, Qi Lin was already a little speechless in shock.

Obviously, the system has already determined that this tree demon has been killed, but now that it's like this, what's the matter?!

"Master, this is not a corpse, this is a resurrection!" Cooper said calmly, but on the word resurrection, he added an accent that he rarely used.

"This thing...... Is it unkillable? ”
