After determining the target, Qi Lin immediately got up and ran towards the deep pit, but at this moment, a wrist-thick vine suddenly shot out from the depths of the forest, wrapped around his ankle, and dragged him to the ground!

“NMB！”

Qi Lin couldn't help but scold, and when he looked back, he happened to see where the alienated tree demon appeared, and the other end of this vine was also connected to the body of the alienated tree demon.

Qi Lin hurriedly swung the bone blade to cut the vines on his feet, but before the bone blade could touch the vines, the vines were like the blood-filled spongy body under the man, and they instantly became extremely hard, and they only cut less than a third of the bone blade, and they also made a small hole in the bone blade!

Moreover, a large amount of blue-black juice gushed out of the cut place, covering all the cut places.

As the vines stiffened, the poisonous barbs on them were also deeply embedded in Qi Lin's flesh and blood, and for a while, all kinds of painful sensations came from the ankles, and as for the toes, they were completely unconscious, as if they didn't exist at all.

"Hiss......"

With a gasp, Qi Lin reached out and touched the backpack, only to find that there was no antidote left in the backpack.

By this time, the alien tree demon had already held the pair of sharp claws on the vine, and was about to drag them back—

"Boiling blood, on!"

"Injury immunity, on!"

The sensation from the calf to the foot revived, and the control of the body also returned to Qi Lin's hands, and with a struggle, Qi Lin broke the vines on his ankles - the hardness increased, and the toughness naturally decreased.

With one hand on the ground, he bounced violently, and then ran desperately to the deep pit in the middle of the clearing!

Boiling blood only for ten seconds, injury immunity for only five seconds, in this short period of time, Qi Lin had to kill that - "heart"!

Climbing over the roots and ravines crisscrossing the ground, Qi Lin rushed to the edge of the pit in three steps and two steps, at this time, just after the duration of the injury immunity ended, the injured and poisoned right leg was weak, Qi Lin's center of gravity instantly fell to the side, and he fell into the pit uncontrollably.

"Bang!"

Qi Lin felt his body slam heavily on something hard, and when the momentary dizziness passed, he looked at it and found that under him was a nuclear warhead that was mostly buried in the soil, and the warhead was full of abnormally developed rhizomes, and on these rhizomes, there were many hair-thick branches, which drilled into the inside of the warhead along the gaps on the surface of the nuclear warhead.

Looking up, the pit was about five or six meters deep, and the walls of the surrounding shaft were crawling with dense roots.

There is a faint phosphorescent flickering inside these roots, and the faint blue-green color indicates that the substances in them have an extremely terrifying radiation concentration, and at this time, the alarm sound of the miniature brain on the wrist can already be described as a piercing scream, Qi Lin looked down - ambient radiation concentration: 894.

"It's okay, it didn't exceed the upper limit of 1000......"

Qi Lin limped around the warhead, and there was nothing outside the warhead that could be called a "heart" except for a rhizome or rhizome.

Faced with this situation, Qi Lin had a feeling of not knowing what to do for a while.

"Could it be...... This warhead is the heart of the Black Forest? Or is the heart inside the warhead? Cooper, did you detect what's going on inside the warhead? Qi Lin asked.

"It should be inside the warhead...... I could feel a slight sound inside the warhead, and the nuclear bomb was dead and could not have moved. ”

"Okay, it looks like I'm going to be a bomb disposal expert again." I don't know why, the alienated tree demon didn't chase after Qi Lin fell into the pit, but it was okay to at least give Qi Lin a relatively safe and stable environment.

Cleaning up some of the roots on the warhead, Qi Lin inserted the dagger into a gap that was propped open by the roots, and pried it hard, priing off a palm-sized metal shell.

"I hope it doesn't explode at this point, it's interesting." Qi Lin muttered.

"Rest assured, master, this warhead will not be able to detonate."

"That's for the best."

Qi Lin concocted the same method, and pried off the surrounding circle of metal shells, which were already seriously damaged and deformed, and then eroded by the roots of the Black Forest, and removing these metal shells was as simple as peeling egg shells.

After dismantling the two layers of metal shells, Qi Lin dismantled a bunch of electronic devices that had lost their function, and finally, a neutron shield made of highly concentrated graphite appeared in front of his eyes.

"It should be inside......

Qi Lin laboriously removed the heavy graphite plate from the metal frame, and when the graphite plate completely left, the radiation concentration around it rose by dozens of points again, and it was already close to the limit that Qi Lin could bear.

Rao also began to feel some discomfort in his body, the skin exposed to the air felt a tingling sensation from time to time, and two lines of crimson viscous blood began to slowly flow from under his nose.

"This ...... It is...... Heart? ”

This is a less powerful uranium bomb, a first-generation nuclear weapon produced in the last century, and the highly enriched uranium block inside is covered with capillary-like roots, and in the densest place of the roots, a translucent "tumor" grows.

The "tumor" was the size of a watermelon, with a smooth surface filled with a dark green glowing liquid, and as the internal light source dimmed or brightened, the "tumor" contracted and expanded accordingly - literally like a beating heart.

"This is the 'heart' of the Black Forest." Cooper said.

"How do you kill it?" Qi Lin asked.

"Looks ...... It's fragile, just stab the dagger into it? Even Cooper, when faced with something he had never seen before, had a hint of uncertainty in his tone.

"It's not going to blow up, is it?" Qi Lin looked at this light bulb-like heart, this thing was a bit like a balloon filled with water, if he stabbed it directly with a dagger, maybe it would burst directly, splashing Qi Lin with the glowing liquid inside.

"It should explode, but the radiation concentration of the liquid inside will not be higher than the current concentration in the environment, that is, it should not hurt the owner."

"Forget it, I'd better be on the safe ......"

Qi Lin took two steps back, pulled out his pistol, opened the safe, and aimed his crosshair at the "glowing tumor"—the "heart" of the Black Forest.

Taking a deep breath, Qi Lin tried his best to make his wrist steady, and then gently pulled the trigger.

"Phew!"
