"Great!" Chen Jianghong clapped his hands excitedly and laughed, it seems that what the bricks called the beasts is true, the eyes of bats are very weak, almost like blind, they rely on the ultrasound from their mouths, and after encountering obstacles, their ears receive the ultrasonic waves reflected back to judge the location of the prey, which is also the secret that bats can accurately hunt in the middle of the night when they can't see their fingers, and the radar on the earth is designed with reference to this principle.

And the boxy metal box that Chen Jianghong took out was to find a manufacturer that produces ultrasonic bat repellent devices, and specially customized a strengthened version of the ultrasonic transmitter, in order to deal with the bloodthirsty bats on the Xianzong Continent, Chen Jianghong deliberately asked the engineer to increase the frequency of ultrasonic waves by ten times.

The working principle of this metal box is actually very simple, that is, it emits strong ultrasonic waves, interfering with the ultrasonic waves emitted by the bats for positioning, which is equivalent to saying that the eyes and ears of the bats are wasted, and they have completely become deaf and blind.

Chen Jianghong took the fire dragon sword, and quietly came to the bloodthirsty bat of the fifth layer of qi refining, the bloodthirsty bat was dizzy and still didn't find Chen Jianghong, but was still scratching the big ears with its claws, it seemed that it was also very confused, the talent and magic power that had never had a problem suddenly became insensitive today, and the reflections to the ears were chaotic ultrasound, it seemed that there was a rocky mountain wall in front of it, and it was about to hit the mountain wall if it was going to go further, and it seemed that there was nothing in front of it, this strange feeling made this bloodthirsty bat of the fifth layer of qi refining almost want to vomit blood, and he didn't know whether he should continue to fly forward or stop？

Chen Jianghong urged the spiritual power of his whole body and transmitted it to the Fire Dragon Sword, and a sword blade more than three meters long suddenly erupted on the Fire Dragon Sword, and the sword blade was still steaming with blazing flames, burning the air a little distorted.

"Die!"

Chen Jianghong jumped up suddenly, raised the fire dragon sword in his hand, and slashed at the neck of the fifth-layer bloodthirsty bat of qi refining.

"Poof!" The bloodthirsty bat's head was neatly cut off, and blood gushed out from the broken neck more than two meters away, like a fountain.

The bloodthirsty bat of the fifth layer of qi refining convulsed a few times, and then fell to the ground and died, and with a wave of Chen Jianghong's big sleeves, he collected the entire bloodthirsty bat corpse capital into the Qiankun ring.

The demon pill of the fifth-layer demon beast of refining qi can sell at least fifty spirit stones, plus the materials on the body, it is another fifty spirit stones, Chen Jianghong rubbed his hands happily, looking at the bloodthirsty bat king who was still flying around, it was like seeing a large pile of spirit stones, dangling in front of his eyes.

"Get rich, get rich!" Chen Jianghong had never thought so much that it was so simple to kill demon beasts, and the bloodthirsty bats were like fat pigs waiting to be killed, and they had no power to resist at all.

Chen Jianghong repeated his old tricks and came to the bloodthirsty bat king again, but this sixth-layer demon beast of qi refining, although it couldn't see or hear, it was very sensitive, it seemed to be able to sense the crisis around him, the whole body was rolling, and the huge bat wings more than five meters long were swaying, like a huge ball wrapping the bloodthirsty bat king, and from the bat wings there were also ice balls with cold air.

Ice hockey balls are in the air, there are a lot of huge bats, as long as they rub the ice balls, they will be frozen into dark blue ice sculptures, falling to the ground and shattering, several ice balls almost hit Chen Jianghong, fortunately Chen Jianghong was prepared, and he dodged away.

"It seems that the sneak attack can't be done, so let's go hard. Chen Jianghong saw that although the bloodthirsty bat king could not see or hear, he had bat wings to defend and ice ball attacks, both offensive and defensive, and he also knew that he couldn't easily kill it with one sword like dealing with the bloodthirsty bat of the fifth layer of qi refining.

"Fire Dragon Sword!" Chen Jianghong pinched the trick with his right hand, and the fire dragon sword flew up violently, growing into a fire dragon with a five-layer cultivation of qi refining and a length of more than a zhang.

"Kill!" Chen Jianghong gave an order, and the fire dragon attacked the bloodthirsty bat king with its teeth and claws.

"Boom!" the huge dragon claws clung to the wings of the bloodthirsty bat.

"Sting!" The bloodthirsty bat's wings were cut open a big hole, and the bloodthirsty bat screamed, waving its claws, knocking the fire dragon out, and at the same time, the spiritual power on the wings flashed, and the wounds on the bat's wings were actually healing rapidly.

"Humph! Let's see how many times you can block it. Chen Jianghong once again commanded the fire dragon to quietly spare half a circle, and slammed it again at the wound on the bat's wings.

"Sting!" was like the sound of tearing the brocade robe, and the bat's wings, which were more than five meters long, were completely torn apart, and even the bones in the wings were broken.

Although the Bat King couldn't see it, with the direction of the fire dragon's attack just now, he opened his mouth and spit out an ice ball.

Chen Jianghong commanded the fire dragon as early as after the fire dragon struck a blow, quietly dodged, turned half a circle in the air, aimed at the back of the bat king, the dragon claws waved, and it was another blow, Chen Jianghong is now bullying the bloodthirsty bat king, he can't see or hear.

In this way, five sneak attacks in a row, the wings of the bloodthirsty bat king are like clothes called Hanako, full of holes, and they have been completely destroyed.

"Squeak!" The bloodthirsty bat roared at the sky, as if telling the resentment in his heart, it was a demon beast of the sixth layer of qi refining, and it was the king of the bloodthirsty bat group in the Ten Thousand Buddha Caves, and now it was actually bullied like this by Chen Jianghong, who only had a third-level cultivation of qi refining, and it was not convinced.

"This is the time. Chen Jianghong pointed forward, and the fire dragon opened its bloody mouth, aimed at the neck of the bloodthirsty bat, and bit down.

"Click! Click!" The neck of the bloodthirsty bat king was bitten into two pieces, and the bloodthirsty bat king still wanted to struggle, but he was weak, and finally died of grief and anger.

Chen Jianghong took back the fire dragon sword, and received the corpse of the bloodthirsty bat king into the Qiankun ring, at least one hundred and twenty spirit stones in hand, Chen Jianghong was in a good mood, holding the ultrasonic bat repellent device, admiring the bats flying in the sky and colliding together from time to time, and walked slowly to the outside of the Ten Thousand Buddha Caves.

I don't know if it's because the working frequency is too high, the ultrasonic bat repeller that Chen Jianghong was holding suddenly sparked, and there seemed to be some wiring burning inside the machine, and a puff of black smoke came out.

"Click, click......" With a strange sound, the ultrasonic bat-repellent device was completely scrapped.

The remaining 3,000 huge bats in the Ten Thousand Buddha Caves suddenly quieted down, and they all turned their heads to stare at Chen Jianghong, they had clearly seen Chen Jianghong again, and they also knew that Chen Jianghong not only stole the elixir of the Ten Thousand Buddha Caves, but also killed their king, this is an endless blood feud.

"Squeak, squeak!" Three thousand bats, like three thousand fighter jets, rushed towards Chen Jianghong frantically with the whistling sound of the air, and they wanted to tear this despicable and shameless thief to pieces.

Although the three thousand bats are not demon beasts, there are more ants and can devour giant elephants, not to mention these huge bats with sharp teeth and claws.

"Damn, Lao Tzu spent a million, you produced this garbage for me, and it took ten minutes to scrap it, it won't be greedy for Lao Tzu's money, cut corners, damn, go back and settle accounts with you." Chen Jianghong threw the ultrasonic bat repellent device at the bat swarm, and then opened the defensive light mask and fled to the outside of the Ten Thousand Buddha Caves at the highest speed.
