The speed of the vampire bat was too fast, so Yang Ling rode his speedy unicorn and deliberately circled around the mountain to lead away the pursuing bats, in order to buy some time for the two-headed ogre and dog-headed man in front. After confirming that they were safe, he accelerated towards the thicket where they had set up an ambush.

  Twenty steps, nineteen steps, eighteen steps...

  After quickly crossing a trench, he ordered the lurking Evil Eye to strike, shooting out a dense barrage of blinding rays. Unexpectedly, however, the vampire bat was completely unaffected, and flew over at an unchanged speed.

  Acoustic detection?

  Looking back at the vampire bats that were closely following, Yang Ling was shocked and remembered the bats' unique super sonic wave detection ability. For them, the most important thing was the pair of protruding outer ears, with their eyes only serving as auxiliary effects.

  Yang Ling continued to sprint wildly after quickly gathering up over a hundred evil eyes inside the trench. Fortunately, the unicorn's speed was fast enough that even though it had paused for a moment, it still managed to shake off the vampire bats that were hot on its heels.

  Sound waves may be able to greatly interfere with their hearing, perhaps 'dolphin sounds' can be used as a talisman?

  He recalled the vampire bat's ability, and his heart moved. He quickly took out the 'Dolphin Sound' talismans he had refined in the space ring over the past few days. Although these 'Dolphin Sound' talismans were refined with the essence of giant crab spiders and double-headed horse spiders, their effect was not as good as those refined with the fresh blood of bush warblers, but they should still have some effect on interfering with the vampire bat's hearing.

  After rushing into the ambush circle, Yang Ling continuously threw out several 'Dolphin Sound' talismans, and then put away the unicorn, pulling Yuna to drill back and forth in the dense spider web. To enhance the effect, he commanded the spider army to lay down layers of spider webs in the thicket. Except for a few meters wide passage, all sides were surrounded, and the deeper they went, the denser the spider webs became.

  Squeak...

  Under the interference of 'Dolphin Sound' talisman, the vampires did not notice the spider web not far away and followed closely while calling out, tracing Yang Ling's scent.

  At first, the spider web was relatively small, with only a few bats being entangled. But as the spider web grew larger and denser, more and more spiders were caught up in it.

  At the same time, under the command of the Wolf Spider King, a large army of spiders quickly wove webs at the entrance, preparing to trap all the blood-sucking bats that rushed into the ambush. More than 2,000 spiders acted together, and soon they sealed off the narrow entrance layer by layer.

  Squeak...

  After breaking through several layers of sticky spider webs, the giant bat, which was all red and felt something was wrong, let out a strange cry and led the remaining bats in a sudden breakout.

  Unexpectedly, under the interference of Yang Ling's 'Dolphin Sound' talisman, he would occasionally crash into a sturdy spider web. The more frantically he dashed about, the easier it was to fall into the trap!

  Helpless, the giant bat could only lead a group of bats to fly back and forth according to their memory rate, but very quickly. It soon discovered that it had been surrounded tightly, with no way out. With nowhere to go, it led the remaining bats to charge forward frantically, tearing through layer after layer of tough spider webs.

  After advancing, the wolf spiders weave a sturdy and dense spider web. Every time they tear through one layer, the giant bats have to expend tremendous effort, and each time they break through, more than half of the small bats are lost.

  After tearing through eight layers of spider webs, the giant bat was finally unable to break free and was tightly entwined in the last layer of web. Every time it struggled, it felt the web constricting even tighter.

  In less than half a watch, thousands of bats were all caught. After confirming that there were no bats escaping the net, everyone came out one after another.

  "Sir, I'll go find some dry firewood and burn them all with one stroke of fire!"

  Watching the bats struggling in vain, Orlando was thrilled and admired Yang Ling to the ground. At this moment, he finally believed that building a city on the shores of Blackwater Lake was not a foolish dream!

  Look at the excited Dog Head Man, Yang Ling chuckled and said: "Hehe, such a good thing, why burn it?"

  "Master, aren't you going to burn them? Are you planning on pickling them as dried rations?" Brasca, the two-headed flesh-eating demon, looked at the emaciated vampire bats with puzzlement.

  "Of course, bat meat is delicious and absolutely better than the black water fish you mentioned. Their roasted meat can be said to be a rare delicacy on the mainland!"

  Roast bat?

  When Yang Ling said that, the two-headed man-eating demon shook his head in confusion. When he was hungry, he had eaten white ants underground and gnawed on hairy caterpillars on trees, but he really hadn't heard of anyone eating roasted bats before.

  The two-headed cannibal monster was puzzled, while the dog-headed man and the heavenly fox Yuna both took a step back. Especially Yuna, who felt nauseous at the sight of the sharp-toothed bat, she would rather starve to death than touch such a monstrous creature.

  "In fact, bats are more delicious when eaten raw!"

  After picking up a weakly struggling bat from the spider web, Yang Ling held it in front of everyone and turned around. Scaring Yuna into a loud scream, she retreated far away, fearing that Yang Ling would let her take a bite of the bat.

  A woman is always a woman!

  Look at the two-headed flesh-eating demon with an unchanged expression, then look at the pale-faced Heavenly Fox Yuna, Yang Ling shook his head and carefully observed the vampire bat in his hand.

  At first glance, the so-called blood-sucking bat didn't seem to be much different from the bats he saw in the countryside when he was a kid. Same claws, same wings...... just about twice as big. But after observing carefully for a while, he discovered something unusual on the bat's tail.

  The vampire bat's tail is very long, with a thin, pointed proboscis hidden under the feathers, looking like a needle tube or a special tail thorn, and inside there is still half a fresh blood. It seems that this is their tool for sucking blood.

  ******

  Out of curiosity, Yang Ling pinched the tail thorn of the blood-sucking bat and accidentally found that he could also squeeze out the fresh blood inside, a big lump at a time. Looking at the fresh blood and then looking at the tail thorn of the blood-sucking bat, an idea suddenly occurred to him.

  Refining witch symbols requires a large amount of magical beast essence, whether it's purchased from mercenaries and townspeople or obtained by sending out a large army to hunt them down. All of this requires a lot of material resources and manpower. Accumulated over time, it's also a considerable expense.

  If you take the opportunity to tame the weakly struggling vampire bats, not only can you get a unique magic beast army, but also get a group of free laborers to collect the essence of magic beasts for you everywhere. Even more, you can use poison to attack poison, let them go against the remaining vampire bats in Blackwater Lake, and reap the benefits of the fishermen.

  After understanding the benefits of vampire bats, Yang Ling no longer hesitated and one by one, he tamed them with their blood. Among them was a giant bat that struggled weakly.

  After smoothly advancing to the land witch, whether it was spiritual power or witch power, he had made great progress. He tamed a thousand first-class magic beasts, vampire bats, without any problems. After arranging the construction of the city properly, he planned to return to Visen Town on a chosen day and cultivate in the Tras Forest, seeking opportunities to tame mid-to-high-level magic beasts.

  Kor, Evil Eye, Spider, plus Gargoyle and Withered Warrior, his low-level demonic beasts may not be many in variety, but their numbers are already sufficient. Next, he needs to tame is the mid-to-high level demonic beast, enhancing the overall combat effectiveness of the demonic army. If the Vampire Bat didn't have the ability to suck blood, he absolutely wouldn't waste his vital energy and magic power on this first-level demonic beast again.

  After domesticating the vampire bats and obtaining their memories, Yang Ling further understood the situation of Heishui Lake.

  According to the giant bat's memory, there are tens of thousands of vampire bats on the shores of Blackwater Lake, divided into more than a hundred large and small tribes. The larger tribes have tens of thousands of bats, while the smaller ones have only a few thousand, or even just a few hundred, each with their own territory. In general, unless they encounter a large amount of prey or enemies, they will not act together, each having their own leader.

  Twenty million?

  After understanding the total number of vampire bats, Yang Ling shook his head and finally understood why the half-beast people didn't dare to go fishing by the lake. With tens of millions of vampire bats, even if each one only sucked a drop of blood, it's likely that many would be sucked dry.

  After resting for a night, in order to speed up the extermination of the vampire bats, Yang Ling decided to divide his troops into two routes. The giant red-haired bat led its thousands of subordinate bats to act alone, responsible for sneaking up on nearby bat tribes, while he himself used old tricks again, sending bait to lure the blood-sucking bats into an ambush circle and annihilating them one by one.

  Three days later, the crowd cleared a safe area on the lake shore and eliminated nearly 50,000 bats. Among them, most of the credit should be attributed to the giant red-haired bat king. Under its sudden attack, the unguarded wild counterparts simply had no time to react.

  In order to improve the efficiency of giant red bats eliminating their wild counterparts, and also to improve their future collection of magical beast blood, Yang Ling once again domesticated a thousand bats, keeping the bat army's numbers at around two thousand.

  In addition, like spiders and evil eyes and other low-level demons, after swallowing the crystal nucleus of the same kind, bats can also advance. Three days later, ordinary bats evolved from the first stage to the second stage, their claws became as hard as iron, and their speed increased by almost a factor of two. Even more rarely, the tail spines grew more than twice as large, capable of holding even more fresh blood.

  Ordinary bats advance to the second stage, after swallowing a large number of crystal nuclei, the red-haired bat even advances directly to the third stage. The wingspan is as long as two meters, and the one-inch-long claws can pierce through the light armor on the dog-headed human body with one blow. Although the speed is still inferior to that of the same third-stage hornet beast, it is not far off.
