He faced the camera, his voice calm as he conducted an engineering evaluation, "What I need isn’t an ordinary bait, but a bait for a massive investment!"

"Currently, my method of obtaining food is a low-efficiency, random system. Whether it’s ice fishing or traps, they rely on prey appearing at the right place at the right time. What I want to intervene with is that probability."

"Therefore, I must invest in a catalyst to forcibly increase the biological density and activity frequency in the target area."

His gaze became fervent, and the returns on this investment had already been clearly quantified in his mind into two highly feasible plans.

"I have always followed the most fundamental survival law, which is to make the best use of everything." He spoke to the camera, his voice calm and focused.

"But my understanding of ’use’ is still at the most superficial level. I ate the fish meat and liver and stored fat."

"Those wastes, fish gills, fish intestines, grouse, and rabbit digestive tracts... these things, I previously just simply stored them and took them out as bait when ice fishing, which is a massive waste."

He extended his first finger and said, "Now, I want to carry out deep processing of these biological wastes to create an efficient nest bait. Then gather the scattered fish into my net."

"That stinging net, now fully relying on luck, I will use all these innards and blood to craft a ’bait block’ that can dissolve slowly. Sink it near the fishing net, and the water flow will carry the scent downstream, forming a long scent trail underwater."

"Fish downstream will instinctively follow the scent against the current, and the endpoint of that path is my stinging net."

He extended his second finger, "And turning animals passing by on land into prey that comes to me."

"That rabbit path currently just waits for rabbits to make a mistake. I will use the more pungent grouse blood and rabbit innards to make bait for land, setting it around the rabbit path trap."

"It’s like placing a sign in the forest, telling all animals hunting rabbits that there’s food here! They will actively follow the rabbit path to find it, and these hungry predators are my hunting targets!"

The return on this investment is so enormous that it is enough to make him resolve to use all the biological materials in his stock viewed as inedible. 𝗳𝚛𝚎𝚎𝘄𝕖𝕓𝕟𝕠𝚟𝚎𝕝.𝗰𝕠𝐦

Lin Yu’an stood up, without any hesitation, and immediately began to put the blueprint he conceived into practice. He first cleared a large, flat stone slab inside the shelter as a workbench.

Then methodically placed all the needed materials on the workbench one by one. "Alright, folks, let’s get started. The first thing to do is process these things considered as waste."

First is the waterproof storage bag containing grouse blood. "Blood, is the pioneer of scent diffusion, its signal can be transmitted the farthest."

Then, he took out from the snow well refrigerator the "scraps" he had deliberately stored, several pieces of rock-hard frozen rabbit innards, some gills and intestines left from previous fish processing, and the innards just taken from the grouse’s body.

He pointed with the knife tip at the pile of varied innards: "These, each carries different biological information."

"The innards of the grouse, especially the contents of the intestines, have a strong smell of fermented plants and berries, which is a typical ’herbivore’ signal that can attract a wider range of omnivorous fish."

"The liver and kidneys of the rabbit are rich in uric acid and unique scents, which is a mammal signal. While fish innards emit same-environment signals and oily aromas in the aquatic environment."

He found a piece of relatively sharp-edged shale outside the shelter and picked up a round pebble, which are his specialized tools for processing this heap of ’biological waste.’

First, he used that shale stone knife to patiently smash the semi-thawed innards, a few Hairy Scale Fish, into a slurry of mixed minced meat.

The process was not elegant, with dark red liver, gray-green intestines, and white fat tissue mixing into a variegated slurry, emitting an extremely complex scent under his powerful pounding.

He would even pick up a section of the grouse intestine and scrape the semi-digested, strong plant fermented acid-smelling content into the mixture with the side of the stone knife, which is the most deadly temptation for omnivorous fish.

He continued to explain, "Simple blood and innards mash will be quickly swept away underwater, the effect time is too short. At zero-degree water temperature, the current will quickly carry them away. I need a binder to make this feast last a little longer."

He already had an idea, he picked up a hard, dry root, "Bulrush Root, these are pure starch. In the wild, this is the highest-grade binder, which can make loose bait compact, slowing down its dissolution speed in water."

Then he placed several dried bulrush roots on another stone slab and began to forcefully grind and pound using the round stone as a hammer.

The friction between the stone and dry fibers produced a "shush-shush" sound, his movements steady and forceful, quickly pulverizing the roots thoroughly until they became a pile of fine, gray-white powder particles.

With everything ready, he began the final mixing, this time, he was going to create two different formulas of bait.
