Chapter 51

**Update Time: April 23, 2013**

How to enter this completely enclosed training ground? There are essentially two methods.

The first is to find a way to obtain the spell to open the stone door, which would allow for easy entry! However, this spell is likely known only to Gongsun Furan, so this path is blocked.

The second method is to create a passage by oneself. However, there is a problem: the main building material is extremely hard, and it has been reinforced by a powerful soul master with a strengthening spell. Ordinary tools cannot even leave a scratch on it! Therefore, Yun Mo had to choose an extremely arduous method—digging a tunnel under the foundation of the building to enter!

After all, the spell only protects the exterior of the building; it does not protect the foundation below! Doing so would increase the cost by several times, and even with Gongsun's wealth, he could not afford it! The current state of the building almost bankrupted him. If it weren't for the need to practice some secret body-strengthening techniques that required utmost secrecy, he wouldn't have spent so much money to build this training ground.

Yun Mo did not know the original intention behind Gongsun's actions, but he knew that this was the only place where Gongsun would let his guard down! And when he relaxed, the bomb would be effective!

Digging a tunnel is not an easy task. Although Yun Mo now has the physical strength to dig quickly, there are still several points that cause him concern.

The entrance to the tunnel must be hidden. If someone above discovers any abnormalities while he is digging below, it would be like digging his own grave!

The soil here must be suitable, meaning it should be easy to dig but not prone to collapse! If it is as hard as granite, can you even dig? If it is too loose and easily flows, a collapse would bury him alive!

Currently, Yun Mo is only at the fourth level of Heavenly Favor, and he cannot yet reach the stage where he can naturally absorb oxygen from his surroundings through his inner breath. If a collapse occurs, he will surely die! Moreover, it has been raining heavily today, and the impact on the underground soil is unknown. So Yun Mo can only take a chance; if these conditions are not met, he will have to think of another method!

He carefully examined the vast building, and when he reached the back, his eyes suddenly lit up. A towering artificial hill, several dozen meters high, appeared before him, surrounded by green trees, and it was only about 15 meters away from the training ground!

He quickly moved to the hill, scanned the surroundings, and, finding no abnormalities, immediately restored his appearance, put away the clothes and armor of Wen Jun, and crouched down in a cave near the ground that could accommodate a person! The ground here was very dry, as the heavy rain was blocked by the vegetation and rocks outside, preventing it from seeping in! Yun Mo focused all his energy, turned his head, pressed one ear tightly to the ground, closed his eyes, and covered the other ear with his hand.

All things in the world have a spirit, so they each have their own unique energy pattern! For example, water has a very gentle energy fluctuation, a vast and inclusive gentleness that can encompass everything and devour the heavens and earth, and can overcome hardness with softness, burying immortals and deities!

In feng shui, where yin energy is strong, one can feel the extremely cold, ghostly, and eerie fluctuations! Every substance in nature has its own unique energy fluctuation, and the soul power awakeners in this world have extremely sensitive senses. Even those with low cultivation can feel these strange fluctuations.

Since Yun Mo experienced a stroke of good fortune and a transformation in his own backyard, he has had this subtle and mysterious feeling, which is now coming in handy!

As he immersed himself in his mental world, he clearly felt all the energy fluctuations beneath the ground!

A worm, about a hundred meters away from Yun Mo, was struggling to move through the shallow soil. It had little intelligence, and its actions were purely instinctive, but the weak life energy it emitted was still sensed by Yun Mo! There were also more intense fluctuations, such as those from rats and other creatures!

The roots of countless plants were deeply buried in the ground, greedily absorbing the nutrients from Mother Earth. This life energy was the most intense, the power of life!

An underground river flowed about 80 meters below Yun Mo. Its water energy fluctuation was not strong, but Yun Mo knew it was there! The remaining energy was extremely heavy and rhythmic, the energy of the earth, the breath of nature!

Yun Mo felt this deep and heavy power, understood the greatness of the earth in supporting all things, and realized that the soil structure here was very compact!

He was moved, moved by his ability to sense these strange fluctuations!

Yun Mo opened his eyes, took out the Luoyang shovel from his storage belt, and with great effort, drove the assembled shovel into the ground to a depth of several meters. Then he pulled the connected rope, and the Luoyang shovel brought the soil from underground to the surface!

This was a very sticky yellow soil. Yun Mo pinched the soil particles with his fingers, feeling the sticky sensation, and his eyes flashed with determination.

"Gongsun Furan, this is heaven's will to destroy you, not my fault!"

This soil was exactly the right type for digging a tunnel. It was sticky, firm, yet easy to dig, and not prone to collapse, making it an ideal material for tunneling! The artificial hill was located behind the building, and the guards usually did not patrol this area. Moreover, the heavy rain today added to the concealment, making the conditions for Yun Mo to dig a tunnel favorable!

Looking through the gaps in the hill and trees at the wall of the building, Yun Mo began to calculate in his mind.

Numerous conversion formulas from his past life appeared in his mind, including distance, pressure, speed, humidity, temperature, ventilation, and angles, all turning into various symbols and numbers. Using the mind of an architect, Yun Mo completed all the calculations in just a few breaths!

It must be said that these data would have required a computer to calculate accurately in his past life, but now he could calculate them clearly with just his mental effort, which was definitely a qualitative leap in his life!

Yun Mo recognized this, knowing that he had become even stronger, and he felt a surge of joy!

With the most efficient and fastest route calculated in his mind, the next step was to turn it into reality!

Yun Mo put away the Luoyang shovel and took out other tools like shovels and began the small project of digging a tunnel!

*Plop!* He dug the first shovel at a 36-degree angle, and then his speed increased, his body fully obeying the commands of his brain. Each tool landed precisely where it should, with an error of no more than one percent! This was an extremely precise value, fully capable of ensuring that Yun Mo could turn his mental plan into reality!

As more and more soil was dug out, Yun Mo's small body gradually entered the underground through the entrance, which was over a meter wide. He bent down and continued digging, sweating profusely, his inner strength rapidly depleting but still barely sufficient!

After digging the inner soil, he could only throw it into the already dug tunnel behind him. The amount was too large, and the storage space in Yun Mo's belt was too small. Otherwise, he could have thrown it into the belt and filled it back up when he came out, which would have been perfect. Unfortunately, this was just a luxury, and Yun Mo shook his head, no longer considering it.

As he dug deeper, the oxygen gradually became scarce, but Yun Mo could still endure it. Digging to about 30 meters underground, he used steel bars from his belt to create numerous support points, sufficient to bear the weight and prevent collapse!

Then he turned at an upward angle underground and began digging toward the predetermined location under the building!

The foundation of the building was 29 meters deep, made entirely of large, solid blocks of bluestone. If he used the Luoyang shovel and other tools to break through, it would take a long time and create too much noise! Therefore, Yun Mo chose to dig deeper, bypass the foundation, and directly enter the interior. This method was clearly safer and more efficient!

Being able to determine the position and depth of the foundation was entirely due to Yun Mo's soul power talent of sensing various energy fluctuations. How could he mistake the hard and solid energy of these rocks?

It is clear that every action has its destiny, and these conditions were perfectly suited to Yun Mo's plan. To be honest, Yun Mo also felt lucky!

Two hours later, it was already the afternoon of the Shen hour! The heavy rain that had lasted all day finally stopped, the dark clouds began to dissipate, and the sun finally showed its face, with a rainbow appearing in the sky. The people in the city lord's residence began to bustle about, servants started cleaning the rain-soaked and dirty houses and grounds, and pairs of guards resumed their normal patrols. No one knew that a little boy was almost exhausted underground!

*Clunk!* After continuous labor for several hours, Yun Mo finally heard the pleasant sound of the shovel touching the stone slab. He stumbled, lying in the tunnel, breathing heavily. The oxygen was not sufficient, his face was flushed, and his forehead veins were pulsing. His body was drenched in sweat, and the strong smell of sweat was even detectable to himself!

All the muscles in his body were twitching and aching, as if he were about to die at any moment!

Yun Mo adjusted his inner breath, enduring the suffocating feeling in his chest, and began to absorb primordial energy to restore some of his inner strength. He knew that he must return to his original state and leave no scent or traces. Gongsun was a top expert, and if he went up with a body drenched in sweat, Gongsun would certainly notice when he entered, and the plan would easily fail!

He knew he had to be cautious, but he did not know that Gongsun, seeing the rain stop, had only received a diagnosis of sudden brain confusion from the physician after a day of research on Hu Changqing, with no signs of poisoning. Thus, he was reassured and led 500 guards to return!

It would take about half an hour to return, and Yun Mo had little time left!

Perhaps it was intuition, or perhaps Yun Mo was a person with good fortune. He only restored some of his strength and then stopped practicing. Instead, he stripped himself naked and rolled in the surrounding soil. The natural soil mixed with his cold sweat enveloped him, making him a mud man. This ordinary smell would be undetectable even by Gongsun!
