Zhang Qing did not rush into the depression, but quickly patrolled around the edge of the depression with Ah Longyin on both sides.

This is Oboni's request to them, before fighting in the swamp, if possible, they must first observe the surrounding environment to ensure that there are no overly fierce beasts around, so as to prevent the movement of their own fighting from arousing the curiosity of the beasts and causing danger to enter.

This is also the reason why they know that the snake will only surface in the evening, but they still come here early. It's just to step on it first and prepare for the smooth capture later.

In less than an hour, the two met at the other end of the depression. Today is lucky, the surrounding wind is calm, not only are there no strange beasts, but even carnivorous beasts have not been seen. Zhang Qing stood on the edge of the depression and looked north, where Oboni had forbidden them to go, but it didn't look any different from the outside.

"Ah Qing, it doesn't seem like there's any danger around, let's go down?" Ah Longyin suggested.

"Okay, your master said that you should have at least twenty feet of snake gall, and that length of snake should be near the center of the depression. But let's find a research on the periphery to study their attack methods and toxicity first, after all, this is the first time we've dealt with these guys. ”

Since he was almost alive, Zhang Qing is basically safety first in everything he does now. And every task is a learning process, and all the research on these things is an improvement for his pharmacist level.

The two of them chose a puddle on the side, which was a small pit about five feet in diameter, ninety percent of the water surface was covered with purple algae, and only a small circle of the surrounding shore exposed the turquoise water surface.

Just now, there were a few small beasts lying on the shore, drinking water carefully. However, when they saw Zhang Qing and the others coming towards this side from a distance, they quickly left the puddle. However, they neither ran to other puddles, nor did they leave completely, they just stood in the distance and looked at this side, probably waiting for Zhang Qing and them to drink the water and leave before returning.

"Tsk, if I knew there were little beasts around here, I wouldn't have bothered to catch this guy on the road. Zhang Qing looked at those little things, and helplessly raised the big-eared rabbit he was holding in his hand.

This is what he had just caught while patrolling the area around the depression, and he would rely on it to lure the big guys in the water for a while.

"Don't forget that we need to catch three more big ones in addition to this test piece, and you don't have enough rabbits. The critters around here are just the right thing to keep you from having to run around. Ah Longyin raised her eyebrows and smiled.

Zhang Qing shrugged her shoulders and said that the young lady was right.

The two of them ignored the little things watching from the sidelines, and walked straight to the edge of the pit.

Zhang Qing looked down along the exposed water surface on the periphery, and found that although the water surface was dark from a distance, it was probably because it was covered by algae, but now he could see that the water in the pit was unexpectedly clear, at least he could clearly see the pit wall around the periphery through the water surface, and he could also see small finger-length fish spinning in the water, drilling in and out of the purple algae.

However, since most of the water surface is covered by algae, even if the sun is shining now, it is impossible to see too deep underwater. It's almost clear above three feet, but it's pitch black three feet below.

Zhang Qing carefully observed the underwater pit wall and found that there were regular traces on it, just like the traces of a python swimming on soft ground. If you look closely, there are faint diamond-shaped scales on it, which are obviously traces of the snake's passage.

This is also the habit of snakes, although they are social animals, but only because they are looking for symbiotic algae. In fact, in addition to the estrus period, the snake is a snake and a hole, and it will also have its own sphere of influence, once other people of the same kind trespass, it will be a fierce battle. And the appearance of a depression like this one, which is full of small puddles, is even more convenient for the snakes here to divide the territory.

The strong get the inner and purple algae lush pools, and the weak can only survive on the periphery, and a snake and a pond will never be shared.

Now I see the traces of snakes on the wall of the pit, which means that there is a snake living in this pool, and judging the thickness of the other party from the traces, it should not be a big guy, and it is just the object that they can use to practice and observe.

"That's it, let's force the guys down there to take a look. Zhang Qing nodded with satisfaction and spoke.

"Okay, let's take the bait. After Ah Longyin finished speaking, he took out a porcelain bottle from the package behind him, and Zhang Qing picked up the unlucky rabbit.

Ah Longyin carefully opened the porcelain bottle, and a strong fishy smell immediately made the two of them frown. Zhang Qing used a knife to make a hole in the rabbit's back, and the rabbit, who was unconscious under the influence of pain, twitched a few times, but Zhang Qing did not take it lightly when he grabbed it, so he did not wake up.

The hare's blood flowed out quickly, and Ah Longyin immediately tilted the porcelain bottle, and a viscous transparent slightly yellowish grease liquid in the sun flowed out and poured it on the rabbit's wound, and the fishy smell became more and more intense.

The liquid fused with the hare's blood and quickly coagulated, and when Ah Longyin saw that the wound had been completely covered, she quickly straightened up the bottle, re-inserted the stopper, and then turned her head and took a big breath, it seemed that she was smoked by the smell.

Zhang Qing had a stronger endurance, grabbed the rabbit and waited, while asking Ah Longyin to tie a black-brown rope to the rabbit's leg.

There was also a large iron hook on the head of the rope, and Ah Longyin carefully attached the iron hook to the rabbit's belly, covered it with the rabbit's hair, and took a strip of cloth to tie it to the rabbit.

After waiting for about half a cup of tea, feeling that the medicine had almost penetrated into the rabbit's body, Zhang Qing carried the rabbit's ears with one hand and slowly sank it into the water, just exposing its head to prevent drowning. This is because snakes only eat live animals, they can keenly detect whether their prey is alive or not, and as long as it is not an animal they strangled, they will never touch it.

After sinking the rabbit into it, Zhang Qing silently counted thirty numbers in his heart, and immediately lifted it out, and then slowly retreated, allowing the water on the rabbit to fall naturally, and the water trails formed a straight line, and finally threw the rabbit at a distance of about one zhang from the puddle, and the bait was finished.

Then the two unfurled their khaki cloaks, wrapped themselves in them, and lay down about a foot on either side of the rabbit, waiting for the snake to take the bait in the puddle.

This is the method that Oboni taught them, and the porcelain bottle in Alongyin's hand contains the medicine that Oboni has prepared a long time ago.

Generally speaking, snakes hunt in the evening. On the one hand, because there are more animals that come to the water to drink at that time, they can calmly choose their prey, on the other hand, the light is poor in the evening, and the animals that come to drink water and eat purple algae will basically indulge in delicious food, and when the snake attacks from the bottom to the water, these animals will react more slowly, increasing the success rate of predation.

But at that time, it wasn't friendly to snake catchers who were humans. Although the animals do not attack each other because they need to drink water and have their stomachs full, even the carnivores come here to get water and purple algae, and do not make a big deal with the herbivores next to them.

But they are allowed to coexist peacefully only in the swamp, and humans are easy to attract the attention of animals because they do not belong to the swamp, and the bold may attack, and the timid may run away, in short, causing chaos by the puddle. Not only will it alarm the snakes in the water, but it may also attract attacks from other fierce beasts.

Therefore, people who have a need for this creature have invented various ways to lure it to the surface during non-predatory times. And Kong Sandao uses the medicine that he is best at.

The bait they concocted smelled very fishy, but it was very irritating for the snake that hunted by smell. By mixing the bait into the wound of one of the animals in the snake recipe and allowing it to fuse with the blood, it will quickly soak into the bait. Then put the bait in the water and let the smell pass through the water to the snake's nose, and they will definitely not be able to resist coming to hunt.

The snake catcher then throws the bait on the ground and hides it himself, and the snake will naturally follow the smell to the shore.

Although the snake is a creature in the water, it is extremely fast and powerful in the water, and it also has sharp teeth and toxins. However, once on the shore, even if it is still very powerful, it can still spew miasma, but for humans on land, it is much easier to catch than underwater.

This potion is worthy of being a bait made by the "poisonous lady" herself, and the snake has no resistance at all. As soon as the two of them were lying on their stomachs, they saw a fluctuation in the water, and then a large purple snake emerged from the river.
