Meng Chao took a deep breath anddived into the turbid spring water.

Enveloped by both his spirit magnet and spirit shield, he seemed to grow into an extremely large mass, and his density became incredibly high.

He sank into the mud deep in the spring water, like a weight sinking into butter.

Very soon, Meng Chao found traces of the underground river water that was hidden under the mud at the bottom of the spring. It was more than ten meters deep.

Judging from the cracks on the broken rock layer that had not eroded, Meng Chao guessed that the underground river water had formed not long ago.

The spring should have formed recently too.

A few months ago, this underground river was probably located in the deeper part of the rock layer. The river channel was surrounded by dense rocks, so strong radiation and high-pollution substances in the river water could not penetrate the rock layer and pollute the surrounding land.

Then, when this underground river secretly flowed farther or split into dozens or hundreds of underground streams, the strong radiation and high pollution broke down and became increasingly diluted.

Even experts with sharp eyes might not be able to see the strangeness of the underground river’s upper reaches.

However, ten days to half a month ago, a moderate-sized earthquake occurred there.

Meng Chao and Lu Siya had joined forces to try and stop the Red Radiance Jade vein explosion one year.

Although the intensity of the instantaneous explosion had reduced by 90%, it allowed a great deal of spirit energy to build up in the rock and soil around the vein, slowly releasing the energy over the next three to five years.

It led to an abnormal magnetic environment with constant large and small aftershocks.

While such aftershocks would not have much effect on humans, it was possible that “tidal energy” could help the superhumans raise their level.

However, if a large amount of spirit energy spurted out from the weak point of the earth’s crustal surface and cut off the underground river, tearing apart the rock layers around the river, exposing part of it to the ground, or diverting it, it would be a piece of cake for the spirit energy to penetrate the soil in a larger area.

As a result, the river water, which was rich in radiation and highly polluting substances, was flowing everywhere, forming a somewhat eye-catching “blood-colored forest.”

“I see!”

Meng Chao thought quickly and figured out the details soon after. “It appears that the guy hiding behind Horizon discovered the unique underground river long ago and used it as a natural sewage pipeline.

“They contracted a piece of land at the source of the underground river. On the surface, they opened a very low-key monster farm, but in fact, they have built a large-scale secret base under the farm to carry out all kinds of dangerous gene modulation and biochemical experiments involving the Blood Flowers.

“The Blood Flowers are the most bizarre existence on Monster Mountain Range.

“It’s one of the culprits that led to the birth of ‘monsters’ and ‘zombies.’

“Of course, there are also countless intelligent and outstanding biochemical experts who are trying to tame this demonic lifeform and make it serve humanity. It will become an accelerant that superhumans can use to break through their personal limits and the barriers of life.

“Due to the danger and sensitivity of the Blood Flower, biochemical experiments involving the Blood Flower have to be supervised and approved in the strictest way.

“Almost every step has to be exposed to the eyes of the relevant departments and the public.

“More than a hundred pairs of eyes may even scan a single page of the experimental notes.

“Moreover, such an exploration in the frontier always operates above the law and line of morality. The slightest carelessness will not only lead to disastrous consequences but also ruin the reputation of the researchers concerned. They will be condemned by the public as heinous demons.

“It’s inevitable that the research on the Blood Flower will be limited and difficult to carry out legally.

“Hence, it’s very normal for some ambitious people who are eager for quick success to attempt to abandon the Supernatural Tower’s approval, public supervision, morality, and the law. They’ll use the most radical and extreme means to speed up their research at all costs.

“Plus, in such research, it’s not surprising to discover traces of the Blood Alliance. It’s even not surprising to find the Blood Alliance involved in it from the very beginning.”

Meng Chao seemed to see a thin, long, and faintly discernible red line that connected the explosion of the crystal warehouse on the Red Creek Project site to the Blood Flower research base deep in Raging Waves Mountain Range.

He felt that he might be able to catch a big fish this time.

“I have to find the source of the underground river,” Meng Chao mumbled to himself.

It was impossible to trace the source directly.

The river channel in the depths of the blood spring had only been formed recently because of the earthquake. It was basically a tributary of a tributary. Even a loach might not be able to crawl through the narrowest part of the river. No matter how proficient Meng Chao was in the art of compressing flesh and bones, it was impossible for him to compress his skull to the size of a coin.

However, that did not present a big problem to him.

Every river had to rely on the situation of the mountains and obey the objective law of “water flowing to the bottom.”

Even if the underground rivers were affected by the high temperature and pressure underground, it was impossible for them to surge upward for a long time.

On top of that, because the earthquake had torn apart the rock layers, the polluted river water seeped into the surface of the earth, forming more than one “bloody jungle.” The only difference was the degree of severity.

Following the distribution of the deformed monsters and the mutated plants, Meng Chao sniffed the scent of the Blood Flower spores, which had a unique stinky and sweet smell. Very soon, he determined the approximate range of the underground river.

In the middle of the approximate range, he found a crack that had opened recently.

The dark crack was not visible. It seemed to go straight to the center of the planet. Hissing noises could be heard from time to time, and bone-chilling air was blowing out of the crack.

The gap was extremely narrow and zigzagging.

It could not accommodate an adult, who wanted to crouch and dive into it for a long time.

Meng Chao simply inserted his arms into the depths of the gap.

Then, he poured his spirit energy into his arms and the joints of his hands.

His muscles and tendons were contracting and bouncing.

His bones were vibrating at a high frequency that one could not recognize with the naked eye or human ears.

Invisible and inaudible waves seeped into the depths of the mountains like surging waves, triggering the resonance of the planet’s magnetic field.

It caused every piece of soil, rock, plant root, and even the carapace and bones of every monster lurking underground within a radius of several dozen miles to vibrate together.

The density and nature of objects were different.

The frequency of the vibrations was also different.

Thousands of vibrating waves pushed and shoved from all directions and returned to Meng Chao’s brain.

So, Meng Chao could naturally use his extraordinary analytical, computational, and modeling abilities to construct a map of the underground rock layers and water system in the depths of Raging Waves Mountain Range in his mind.
