Under Xu Xin's gaze, the mutated vines that had been wrapped around the heart layer by layer had untied the outermost layer. Dozens of vines were flashing red light and swaying gently to the rhythm of the beating of the "heart".
"Damn it!" Xu Xin cursed inwardly, then turned around and whispered to the four beasts, "I'll shoot the burning arrows in a moment. Once we're sure the vines are burning, we'll run to the ground as fast as we can. Got it?"
Several animals nodded in response.
He calmed down and loaded a flaming arrow into the crossbow.
Looking into the interior of the underground space, dozens of vines were swaying around the vine ball, covering it, like a row of guards guarding the "heart".
Xu Xin narrowed his eyes, aimed at the gap between the vines, and pulled the trigger.
"Swoosh—" With the bonus of the blue-level crossbow, the burning crossbow shot at a very fast speed. Because of the friction with the air, the crossbow created sparks the moment it was shot, leaving a streak of light in the air.
As long as there is no obstruction, you can pass through the gaps in the outer vines and hit the vine ball inside!
But the opposite happened. Dozens of vines on the periphery suddenly rioted the moment the burning arrow lit up!
Several blood-thorn vines swung towards the burning crossbow at such an incredible speed that they actually threw the burning arrow aside. The rest of the vines all attacked Xu Xin.
"Fuck!" Xu Xin hid back in the corner in an instant. Several blood-marked vines stabbed at him in an instant, brushing against his armor and piercing straight into the wall of the passage.
The wall was not made of rock but dry soil, and the blood-thorn vines penetrated several meters deep!
Just as they were about to pull them out and continue attacking, Mimi suddenly jumped up, a few silver lights flashed, and several vines inserted in the passage were scratched into pieces.
At the same time, fire suddenly ignited in the underground space!
Xu Xin looked over and saw that it was the burning arrow that caused the fire. It turned out that although the burning arrow did not hit the vine ball inside, it was thrown to the root of a blood-patterned vine at the edge, instantly igniting it!
Beautiful! The vines here are so dense that if one vine is ignited, the others will be affected!
However, the next scene opened Xu Xin's eyes and made him widen his eyes.
All the surrounding vines actually gave up attacking Xu Xin and began to fiercely attack the burning blood-veined vine!
After being whipped and pierced countless times, the vine was shattered into pieces, and the flames on it were extinguished, leaving no chance for the flames to spread.
These vines can actually prevent fires!
This happened in just a few seconds, and Xu Xin's hands did not stop, as he had already assembled an explosive crossbow.
"You guys, cover your ears!" After saying that, he pulled the trigger.
"boom!"
Although the explosive crossbow was also hit by the blood thorn vines, at the moment of being hit, the crossbow let out a loud roar, and blew half of the blood thorn vines that were hitting it!
He was going to use the explosive crossbow to blast a gap, send the incendiary crossbow in, and ignite the vine ball!
As the smoke cleared, Xu Xin fired another explosive crossbow at the position he had blasted open.
The few intact vines protecting the surroundings swung towards the flying explosive crossbow, while the other vines all attacked Xu Xin!
Xu Xin hid back in the corner again, and the blood-thorn vines lashed at the entrance to the underground space continuously. Several blood-thorn vines directly pierced the wall at the corner.
Suddenly, Ah Fu let out a piercing scream, and the vines that were about to be retracted after the attack suddenly froze. Xu Xin's sharp eyesight caught the slight cracks that appeared on their branches due to Ah Fu's sonic attack.
Ah Fu's attack is very effective in the cave! And it still has no effect on him!
At the same time, Mimi and Silver King both jumped up and attacked several frozen vines, tearing them into pieces in an instant.
Xu Xin did not stop his actions. He loaded the explosive arrows and continued to bombard the previous position.
The few remaining vines on the periphery were all thrown towards the explosive arrows. With a "bang", these vines were blown in half, and the remaining half flickered slightly with the beating of the heart.
They could have avoided the explosion and could have easily avoided it with the speed of the vines, but the real mission of these vines was to protect the heart behind them. Xu Xin saw their determination to defend the "heart" behind them to the death and attacked the enemy without mercy, resulting in only half of them being left.
Suddenly, the beating of the "heart" became more violent, and the half of the vine machine swinging on the ground also emitted a bright red light, and began to repair and grow at an extremely fast speed!
The second layer of the vine ball also began to move, showing signs of loosening. Once they started to move, there would be another batch of vines that could attack. Under the endless regeneration and attacks of these vines, it would be impossible for him to hurt the blood-red beating heart!
Now is the time!
Xu Xin quickly loaded a burning arrow and shot it directly!
At this time, the first batch of vines had not yet grown and repaired, and the second batch of vines had not yet fully moved. The burning arrows accurately shot at the vine ball, and instantly, part of the vine ball began to catch fire.
Because the vines on the vine ball were distributed very messily, the flames instantly ignited many vines and began to spread.
Xu Xin did not stop there. He continued to quickly draw the bow and shoot, until he fired the fourth flaming arrow, which was then blown aside by the first batch of new vines.
However, the three previous burning arrows had already caused three burning points on the vine ball, which quickly spread, causing most of the vines to catch fire!
The regenerated vines on the periphery frantically hit the burning vine ball, but to no avail. The juice of the vines themselves was a very strong fuel, and the fire spread rapidly.
There were even a few vines that were set on fire and twisted in the flames, and were attacked by their former companions and torn into pieces.
"Let's go!" Seeing that they were unable to put out the flames, Xu Xin immediately climbed onto the wolf's back and crouched on the Silver King's back. When the Silver King saw Xu Xin lying down, he instantly launched himself and rushed towards the ground.
The passage is two meters wide and high, and the space is quite spacious. You may hit your head during normal riding, but it is no problem to lie on the back of Silver King.
The distance was less than one kilometer, and it only took the Silver King a few tens of seconds to rush out. Soon, the man and four beasts rushed to the ground.
Xu Xin rolled over and looked deep into the cave. Thick smoke filled half of the passage and was rolling upwards.
To be honest, he thought that this section of the road might be dangerous. Ji Chaoyang lost contact with him on the way up.
What on earth happened to that guy? He suddenly lost contact for no reason.
Among the explorers, Wang Lei had just escaped from the tracking of those mutated flying insects.
Wang Lei: "Oh my god, those bugs are finally gone. My face is so swollen that it hurts so much..."
Qi Xuefei: "Apply blue-level hemostatic grass. Don't save money when you get hurt. I have a lot of hemostatic grass."
She was quite generous. However, Wang Lei had forced himself out to explore under her suggestion, so it was reasonable to provide him with protection in this regard.
Wang Lei: "Then I can be used!"
Qi Xuefei: "Use it, use it."
Wen Guixin: "... I have explored the second cave. It is still not the heart that Xu Xin said. But it is the same as yours. There are several big red flowers and bugs."
Xu Xin: "I saw the 'heart'."
Xu Xin told them about his experience and told them that if they saw a flesh and blood heart, they should not test it but directly shoot a flaming arrow at it.
If he had lit the heart before it lit up, there wouldn't have been all the trouble later.
Thick smoke was billowing out of the cave, carrying with it a pungent smell of burnt grass. It seemed that the vines below were badly burned.
Li Wenxi: "Wow, this sounds so dangerous..."
Zhao Xiaochuan: "When I think of such a big beating heart of flesh and blood under my tree house, I panic. Brother Xin, we can't contact Boss Ji now, so we have to rely on you to save us!"
Qin Yunlong: "What happened to Ji Chaoyang? Is there any accident?"
Wang Lei: "Hey, Boss Ji is so strong, what can happen to him? His name is not ashes, and he is alive and well. Brother Xin was out of contact for a long time when he was in the underground city, so he must be fine. By the way, burning the vines with fire sounds so cool! You can't use fire in the forest, I have wanted to try it for a long time!"
Wang Lei was optimistic, but he also reminded Xu Xin that Ji Chaoyang might have arrived at a place where his watch had no signal, just like he did in the underground city.
However, he lost contact when he was far away from the heart. Where could he go? He could only walk outwards in the passage, but there was no place without signal.
Wait. What Ji Chaoyang told him at that time was that he left and was far away from his heart.
But this doesn't mean he's out. Maybe he's still underground and found another passage. With his hearing, it's possible that he heard some sound and found another entrance.
Xu Xin looked at the cave where smoke was still billowing. Could it be that there was a passage leading to other places underneath
Wen Guixin also spoke in the group: "Vine group? Hmm... I don't need to use fire. If I use fire, I will have to run away. I'd better use my own method."
When Xu Xin came back to his senses and saw what she said, he immediately smiled bitterly and shook his head.
In terms of combat power alone, he really had to look up to Wen Guixin. She was no longer shy about it and told them directly that her high combat power was due to her special abilities, but she never said what it was.
I don’t know what kind of special abilities she has, it’s really enviable.
The thick smoke had slowly turned into thin wisps of smoke, and it looked like the fire below was almost over. There was limited oxygen underground, so the fire couldn't last long.
Yin Wang and Mimi lay in the leeward place, while Ah Fu lay on Mimi's back, quietly waiting for the smoke to dissipate. Ke Ke was curiously running around the smoking hole, and was accidentally smoked by the smoke, which made him black all over, even his big tail was black.
Xu Xin didn't know whether to laugh or cry. He picked up Coco and slapped it hard.
"Boo! Boo!" Keke protested, but to no avail. Xu Xin didn't want such a little coal ball to crawl on him.
Fortunately, Coco has a natural talent for cleaning. He discovered when he was bathing it before that there was basically no dust on the little guy, and the bath water was still very clean after the bath, so he just patted it a few times, and a brand new little panda appeared.
Coco climbed up his arm and onto his shoulder.
Finally, the black smoke stopped coming out of the cave.
Go down and take a look as soon as possible, to prevent more vines from growing back again.
This time he was not so careful. He directly jumped onto the Silver King's back and rushed into the cave.
Although the thick smoke had basically dissipated, the pungent smell of burnt lakes was still there upon entering, which made Xu Xin's throat itch and he coughed a few times.
The smell of the burnt vines is quite pleasant if you taste it carefully, a bit like roasted eggplant.
I'm hungry, I must have a big meal when I get home.
There was still some smoke near the cave entrance. The closer he got to the bottom, the less smoke there was, and in the end he no longer had to cover his nose.
Coming to the corner, Xu Xin took a look inside.
"Haha, that's so miserable!" He couldn't help laughing.
The entire underground space has been blackened by smoke, and all the vines have been burned into black ashes on the ground. Only a few short vines are left lying on the ground, but they have lost their luster and look dead.
The fleshy "heart" in the center was completely exposed and had suffered severe burns. The surface of the heart had been burned, and you could even smell the smell of barbecue if you got close.
The whole heart became dim at this time, and the beating speed slowed down a lot.
As if it had sensed Xu Xin's arrival, it lit up again and beat faster, but it was much worse than the previous one that was wrapped in the vine ball.
In the black ash on the ground, a few vines that seemed to be half dead moved, glowed faintly red, and began to slowly repair themselves.
Xu Xin naturally would not give the heart another chance. He raised his crossbow and fired an explosive crossbow. Without the protection of the vines, the heart was an immovable oversized target.
"Boom!" The explosive crossbow exploded on the heart, and countless flesh and blood flew everywhere. The heart in front of him suddenly lit up, then dimmed, and began to contract violently. Xu Xin could even hear the sound like a scream due to the contraction.
"Bye now!"
“Boom!” “Boom!” “Boom!” “Boom!”
The continuous explosions failed, and Xu Xin's ears had now adapted to the huge sound. The entire cave was shaking, and the charred walls and broken soil on the cave ceiling were scattered, and some palm-sized pieces of meat were scattered everywhere because of the explosion.
Xu Xin stopped what he was doing, and after the smoke cleared, a piece of meat with a big hole in it appeared in front of him.
The beating was already very weak.
He pulled out his iron-tipped spear and ordered, "Silver King, Mimi, go ahead and kill this heart once and for all!"
“Ah!” “Meow!”
The man and two beasts jumped up, Xu Xin's sharp spear pierced into them fiercely, Mimi's claws almost became afterimages, countless flesh and blood flew everywhere, and the Silver King bit the injured heart madly, and he could tear off hundreds of kilograms of flesh and blood with just a turn of his head.
Finally, the heart could no longer bear the heavy burden, became completely dim, and stopped beating.
Kill the heart of the mutant plant and get points: 300 points.
300 points!
If it is five times the points during the hunting activity, that would be a full 1,500 points, enough to deal with three intermediate mutant beasts!
Xu Xin picked up a palm-sized piece of meat from the ground.
Obtained mutant plant heart fragment (green) * 1.26kg
Mutated Plant Heart Fragments (Green): Burned in fire, it will produce smoke that can drive away the mutant plants. Each kilogram can last for one hour.
Can smoke from burning drive away mutant plants
Xu Xin's eyes gradually widened.
Found it. Isn't this the key to help other survivors survive this tree house defense battle? As long as this thing is used to drive away the mutant plants, there is no need to kill the underground heart. Other survivors can also hold on until the tree house protection period ends!
But this involves the question of whether Xu Xin will give it to them.
Do the weak have to rely on the strong in this activity? Even the activity is helping Xu Xin and his team to build a team!
Xu Xin took a look at the broken heart in front of him. It must weigh several tons!
Suddenly, he saw something emitting light in the center of the broken flesh and blood of the heart.
What is that
