If only the plant heart was defending his tree house, such an attack might really put him in a state of panic.
But he still has the tree house heavy crossbows and electric nets, especially the explosive crossbows. The denser they are distributed, the greater the damage caused by the explosive crossbows!
A strange and harsh sound was heard, the same whistle as before!
The army of mutant creatures moved at the sound, and the neat and dense army suddenly jumped up and rushed towards Xu Xin's tree house!
"Attack!" Xu Xin shouted.
Lou Feier immediately took control of the heavy crossbows around the tree house and launched an attack!
The two tree house crossbows that could hit the northwest were slightly raised, and they kept firing explosive crossbow missiles in that direction!
Countless crossbow bolts were shot in parabolas towards the army of mutant creatures a hundred meters away. Just two crossbows created a scene of overwhelming crossbow bolts!
The mutant creatures were very agile. Despite the overwhelming number of crossbows, they still maintained high-speed movement. Most of them avoided the attacks by slightly tilting their bodies to the side.
But they don't know that this is not an ordinary crossbow, but an explosive crossbow with an explosive range!
Continuous flames lit up among the beasts!
"Boom! Boom! Boom!"
A thunderous roar rang out, accompanied by the screams of countless mutated creatures. Smoke filled the jungle, and blood rained down, dyeing the remaining white snow surface around it red!
The originally well-organized army of mutant creatures was disrupted by the explosive crossbow before entering the hundred-meter area of the plant's heart, and the whole army fell into chaos.
Xu Xin also heard countless sounds of gaining points.
He glanced at Lou Feier, who was constantly manipulating with both hands, and asked, "Did you receive any points reminder?"
Lou Feier was stunned for a moment, looked up at Xu Xin, and then shook her head: "No, after I was contracted by you, I haven't passed it once. All the points I should have earned should belong to you."
Lou Feier didn't care and continued to operate the control panel to attack. An excited smile appeared on her face again, and her hands slid rapidly: "I will bomb, I will bomb! I will bomb you to death!"
As a prisoner, she was now very self-aware and felt that it was normal for her points to be confiscated by her master. Moreover, in her opinion, there was nothing good in the points mall, so it didn't matter whether she had points or not.
Even if there are new good things in the future, as long as she behaves herself and doesn't cause trouble, why would she be afraid that Xu Xin won't give them to her?
Of course, the only downside is that without a warning sound, she has no way of knowing whether she has killed the prey, and can only rely on her own feelings to confirm it.
Xu Xin is also very satisfied with this mechanism.
As a contracted beast, Silver King Mimi's points earned from killing mutant creatures all belong to Xu Xin. As a contracted beast, Lou Feier should also do the same.
Moreover, his points mall has the lowest 30% discount among all survivors, and points can play the greatest role on him.
Suddenly, a sharp whistle sounded again, and the mutant creatures that were blown to pieces by the explosive crossbows on the front line rushed out from the smoke.
Most of the mutant creatures at the front line had died under the bombardment of explosive crossbows. Only a few were able to rush out, and their bodies were covered with scars and blood, looking horrible.
But even so, their speed did not slow down, and they rushed into the plant heart area within a hundred meters.
Suddenly, the ground cracked again, and vines emerged from the ground, directly piercing the first batch of mutant creatures that rushed in and easily solving them.
However, the mutant creatures at the back, which were not seriously injured, suddenly jumped up and launched a fierce attack on the vines that were attacking and absorbing the first group of mutant creatures.
The first batch is used as bait, and the second batch attacks. It is a good strategy.
"Why stop? Keep hitting them!" Xu Xin scolded when he saw Lou Feier stopped moving.
"But... they have already mixed in with the vines. These vines must be our own. I..." Lou Feier didn't know what to do.
Although she didn't know why these vines protected their tree house, since they cooperated with them in attacking the mutant beasts, they were on their side. They couldn't attack their own people, right?
"Who told you to attack within a hundred meters?" Xu Xin really wanted to slap her head. "Hit those behind! Make them all disabled before they get within a hundred meters. That way, the vines will be easier to attack!"
"Oh oh oh!" Lou Feier immediately started working again, and then said a little embarrassedly, "Isn't my attention completely focused on these vines? Um, can you tell me, what are these vines?"
"Focus on your attack. I'll tell you when this crisis is over."
"Understood, sir!"
Xu Xin's attention was always on the intermediate mutant creatures on the side of the mutant army.
On the map, their red dots are much brighter than those of other mutant creatures.
They are not in a hurry to enter yet, watching these low-level guys being eliminated one after another, indifferent.
Xu Xin felt that the plant heart might not be able to deal with them while also dealing with the army of mutant creatures.
These guys need to be dealt with by other means.
"Xu Xin! The explosive crossbows are almost used up!" Lou Feier operated the control panel, a bead of sweat dripping from her forehead, and shouted to Xu Xin.
Xu Xin immediately filled the two explosive crossbows with ammunition. He had more explosive crossbows than he could use up.
Under the coordinated attack of the explosive crossbow and the plant heart, hundreds of mutant creatures were killed, but only a small part of the mutant army was consumed.
