"Do you have any plans?" asked Bertha curiously.

"Yes, but the success rate is not guaranteed. Adam thought for a moment and continued: "When bats fly, they emit a special sound wave that bounces back whenever it hits an object while flying. After receiving these bounce signals, the bat will know what is in front of it, and according to this characteristic, I specially asked the refiner to customize a few small props that can interfere with the sound waves of the bat according to my requirements. This prop is fine if it is against ordinary bats, but in the face of this Black Bolt King effect, I dare not guarantee it, so this is one of the means"

"The second means is to rely on you to get vines, bats generally gather in caves, tree holes and rock crevices, and in the environment of a layer of holy towers, plus the size of the Black Bolt King's population may be very large, so I think there is a high chance that the Black Bolt King will find a big cave to live in, then you need vines to come in handy, then I need you to use vines to seal the cave entrance, of course, before sealing the cave I will also throw a few noisy props and my high-grade animal oil into the cave entrance. ”

"It's animal oil again, is this thing so useful?" Bertha said a little speechlessly.

"Of course, at this stage, as long as this animal oil is used well, it is an invincible weapon. Adam coughed and continued: "I just said that after my demon put the noise-making props and high-grade beast oil into the entrance of the cave, you are sealing their exit with vines, and under the double attack of noise and flame, the little bat inside is also completely disabled, so we only need to resist the spirit attack of the Black Bat King to successfully kill it." ”

"Oh, oh. It's pretty complete. ”

"Of course, if this plan fails, I still have a backup plan, but when I use a backup plan, it also means that our situation is already a bit dangerous. ”

Adam explained the plan to Bertha while looking at the map to lead the way, and after three hours of walking, Adam stopped by a rock.

Adam hid behind the rocks and said to Bertha, "All the caves around here have been searched, but there is only one cave left in front of me." Bertha, send the vines to check it. Be careful not to let the bats find out. ”

"Good. ”

Bertha began to control the vines with all her heart, and several vines slowly entered the cave and began to check.

Bertha's expression was sometimes wrinkled and sometimes stretched, and after a few minutes, Bertha opened her eyes and said in a low voice: "The cave is very deep, more than two hundred meters. There are still dense bats on the top of the cave, guessing that at least three hundred are up, as for whether there is a black batter king in the cave, it may be because the black batbeat king is sleeping with a restrained breath. Through the vines, you can only feel a powerful aura in the depths. ”

Adam listened to Bertha's words, his expression also changed, and he said in a deep voice: "Okay, I understand. You rest first, and I'll think about countermeasures. ”

Through Bertha's feedback, there are two points beyond Adam's imagination, that is, the depth of the hole and the number of small bats, calculating his own materials, it is difficult to cover comprehensively, that is to say, after a set of processes, bats can basically survive as long as they run to the depths, which is completely opposite to what he expected to wipe out most of them. The difficulty of the Black Bat King lies in those little bats, if you don't get rid of the little bats first, you don't need the Black Bat King to make a move, and the little bats can beat the two of them and run away.

Bertha looked at Adam frowning and thinking, and said softly: "Adam, if you have any difficulties, just tell me." See if I can help you out?"

"yes, and you. Adam frowned, and told Bertha what troubled him.

After hearing this, Bertha shook her head helplessly and said, "I thought that what was the matter, I would have said this matter earlier, and it would have been solved earlier." ”

"Really?!" Adam's face was delighted, "What do you mean by that?"

"That's my seed, of course. Bertha smiled and said, "My seeds have a lot of functions. For example, the fire you need most right now, I can solve it with a few explosive flowers. ”

"Exploding flowers, exploding flowers?"

"yes, literally. Bertha said as she took out a seed of an exploding flower and placed it in Adam's hand.

"Is it a red-patterned seed?" Adam asked, taking a closer look in the dim light, "And can you revive this explosive flower with revival of it?"

"Looks like it's okay. Bertha put her finger on her cheek and said cutely, "I haven't tried it yet, but theoretically as long as there is wreckage after the explosion is over, it can be resurrected with resuscitation." ”

"Do you remember the explosion range of the exploding flower?"

"If you think about it, it's about ten meters in diameter. ”

"About ten meters. Adam thought for a moment and asked, "Then can you freely control the explosion time of the explosion flower, and how much does the explosion flower consume your spirit?"

"The control of the explosive flower is not a problem, and if it is consumed, it is about the amount of spirit that grows ten ordinary vines."

"In that case, how many Explosive Flowers do you have?"

"That's a lot, just say it. ”

"Alright, I need you to release thirty Explosive Flowers, and blow one every second. But if there is a bat that is not afraid to rush towards the explosive flower, it can also detonate the explosive flower in advance. ”

"No problem. ”

"Well, having you saved me a lot of effort. Adam was very pleased and said, "In that case, I will change the plan a little." Later, you control the oil-soaked vines to slowly enter the cave with the explosive flower, as for the depth, as far as you can go as deep as you can, as long as the bat finds it, quickly stop moving, and then seal the hole with the vine and start to detonate the explosive flower as planned. ”

Adam took a breath, "This way, the range of the explosion flower will be greatly improved, and the effect will be much better, and under the violent explosion, the group of bats will definitely be destroyed." Even the Black Bolt King will take some damage, and it will be much easier for me to fight the Black Bolt King after that. ”

At this time, Adam scratched his head and said a little embarrassedly: "I'm ashamed to say that it's my mission, but most of the battles are for you to do." ”

Bertha said seriously: "Your business is my business, this is nothing. ”

"Bertha, if you don't say a word, your business is also my business. ”

"Yes~" Bertha smiled from the bottom of her heart.

The plan was about to be implemented, Adam did the first work, and Bertha began to follow the plan, controlling the vines and carefully entering the depths of the cave with the exploding flowers that had grown.

Ten minutes later, the vines had penetrated about one hundred and fifty meters into the deep cave.
