As Bai Zhenzhen fiercely battled the numerous Qi Refining experts, Zhang Yu implanted the acquired Heavenly Spirit Root into his Dantian, initiating the fusion of the spirit root with his physical body.

The Heavenly Spirit Root Zhang Yu chose for Foundation Establishment was the Qi Sea Spirit Root.

Fu Ji stated, “Different spirit roots yield vastly different effects upon Foundation Establishment.”

“Using a combat spirit root for Foundation Establishment results in a rapid increase in combat prowess afterward, but in the long run, it’s less promising than a cultivation-oriented spirit root.”

“But after your Foundation Establishment, you’ll need to fight some pure cultivation spirit roots… so it’s not quite suitable for your current situation!”

“After much deliberation, the Qi Sea Spirit Root is the most fitting for you!”

Zhang Yu agreed with Fu Ji’s suggestion.

The Qi Sea Spirit Root, nicknamed the “Wall-Penetrating King,” boasts the greatest advantage of having a large coverage area and the ability to penetrate various walls, buildings, sand, earth, and stone, enabling the absorption of spiritual energy over a vast area!

This would not only enhance his future cultivation efficiency but also improve his mana recovery during battles!

Using the Qi Sea Spirit Root for Foundation Establishment offered both cultivation potential and combat power enhancement!

As Zhang Yu guided the Qi Sea Spirit Root into his Dantian, the root seemed to take hold and sprout, extending crystalline rootlets that burrowed into the surrounding mana!

Instantly, the surrounding spiritual energy surged in, flowing into his Dantian along with Zhang Yu’s breathing!

Next, as Zhang Yu continuously injected mana into the Qi Sea Spirit Root, the spirit root seemed to be stimulated, continuing to sprout and spread throughout the entire Dantian!

When Zhang Yu injected 60 units of mana into the spirit root, it underwent a qualitative change, with crystalline tendrils spreading and growing along his meridians!

The entire Qi Sea Spirit Root, originating from Zhang Yu’s Dantian, gradually merged with the meridians throughout his body, becoming a part of Zhang Yu’s body, his new organ!

As the spirit root gradually integrated, more and more spiritual energy surged in, and Zhang Yu could feel his range of spiritual energy absorption increasing!

From an initial 50 meters, it expanded to 60 meters, 80 meters, and then 100 meters.

At this moment, Zhang Yu felt as if he had become a massive funnel in the world, frantically devouring the spiritual energy within a hundred meters!

“This is the true power of the Qi Sea Spirit Root… after becoming a part of my body?”

Simultaneously, as the Qi Sea Spirit Root took root and sprouted in his Dantian, and its tendrils fused with his meridians, Zhang Yu felt that with every breath he took, every pore on his body was breathing in the spiritual energy of the world!

The speed at which spiritual energy and mana circulated within his meridians also increased exponentially!

If the original movement of mana in his meridians was like a car driving on a mountain path!

Then, from this moment on, when Zhang Yu circulated mana in his meridians again, it felt like a car driving on a highway!

The efficiency of mana absorption and release, circulation speed, mobilization scale, and output scale… all experienced a surge at this moment!

As this mana efficiency increased wildly, Zhang Yu’s immortal cultivation underwent a qualitative change!

A realization flashed through Zhang Yu’s mind: “Mana… is like the power source of the Immortal Path!”

“As the efficiency of this power source increases dramatically, the operation of all my techniques, and the effects they bring, are all enhanced!”

“It’s like putting an engine on an old bicycle!”

With the influx of spiritual energy, the mana that Zhang Yu had expended due to the spirit root fusion began to recover rapidly!

Even after the mana recovered to 100 units, the refinement of mana did not stop!

Instantly, the original limit was broken, and Zhang Yu’s mana directly broke through to 100.1, and then continued to increase wildly!

Clearly, with the fusion of the spirit root, Zhang Yu’s mana limit was also broken!

This wild increase in mana only slowed down after reaching 180, and finally stopped at 198.4!

After this boundary-breaking surge of mana within his body, Zhang Yu’s Dao Heart also began to stir.

So Zhang Yu visualized the Crippled Ox in his mind and began to circulate the Heart Sutra!

Not the Crippled Ox Abandoning Self Heart Sutra of the Qi Refining stage, but the Foundation Establishment stage version authorized by Deng Bingding this time!

The Crippled Ox in his mind seemed to roar to the sky, the surrounding mud churning and surging, as if turning into pairs of dark hands trying to drag it into the depths of the mud!

But the Crippled Ox’s figure had grown larger, with more knife wounds, injuries, burns, and various other scars, yet filled with a sense of sanctity, emitting a faint white light!

The white Crippled Ox appeared even more proud and unyielding in the rolling black mud!

Dao Heart Level 10 (100.0) -> Level 11 (0.1)!

With the successive breakthroughs in mana and Dao Heart, Zhang Yu could already feel the stirring of his physical body!

His muscles twitched all over, and the surging mana was converted into Longevity Mana, starting to cultivate the Foundation Establishment stage Eternal Spring Boundless Zen!

His body was like land that had been dry for a long time, crazily absorbing the nourishment of Longevity Mana, and then also breaking the boundary, raising his physical strength to level 10.01!

Dao Heart Level 11 (0.1), Mana 198.4, Physical Strength Level 10.01.

Feeling the surging power within his body, Zhang Yu understood at this moment that he had truly entered the Foundation Establishment realm!

And from this moment on, his Dao Heart, mana, and physical body could continue to improve!

Among them, the upper limit of Dao Heart level reached level 20, the upper limit of mana was 300, and the upper limit of physical strength was level 20!

But Zhang Yu did not continue to cultivate his Dao Heart, mana, or physical strength, because it would be difficult to make significant improvements in these areas in a short period of time!

And at this moment, he urgently needed to improve his combat power, so the best way was… Zhang Yu looked at the Nine Heavens Cloud Soaring Force in his mobile phone!

This was the last Foundation Establishment stage technique that Deng Bingding gave him, in addition to the Crippled Ox Abandoning Self Heart Sutra and Eternal Spring Boundless Zen, and was also the so-called military-grade technique!

Combat Technique – Nine Heavens Cloud Soaring Force Level 0 (0/1).

After switching the system to Nine Heavens Cloud Soaring Force, Zhang Yu also began to cultivate this technique that could only be practiced in the Foundation Establishment stage!

“Nine Heavens Cloud Soaring Force… the Foundation Establishment stage technique created by the creator of the Boundless Cloud Hand!”

“Like the Boundless Cloud Hand, it doesn’t focus on moves, there are only three moves back and forth, which makes it convenient for me to practice!”

As Zhang Yu finished practicing the first round of the Nine Heavens Cloud Soaring Force, countless scenes flashed through his mind, and his understanding of this technique was completely mastered!

Nine Heavens Cloud Soaring Force Level 1 (0/10).

“This technique and the Boundless Cloud Hand are completely in the same vein…”

“This is simply a technique choice tailored for me, Deng Bingding must have done it on purpose, right?”

When cultivating the Nine Heavens Cloud Soaring Force to level 5, Zhang Yu could feel that the power of this military-grade technique had surpassed any of his actual combat martial arts!

But Zhang Yu no longer had the mind to continue practicing!

After all, the more he practiced, the greater the danger Bai Zhenzhen would face!

So Zhang Yu’s figure flickered, and he rushed towards the battlefield where Zhenzhen was at full speed!

Zhang Yu had just arrived at the battlefield when he saw the scene of Bai Zhenzhen being captured by Zhou Yang!

Although he didn’t recognize who Zhou Yang was after changing his appearance and form, it didn’t prevent the intense killing intent from rising in Zhang Yu’s heart!

198.4 units of mana roared wildly in his body, turning into streams of milky white Formless Cloud罡 surging out!

Without using the newly cultivated Nine Heavens Cloud Soaring Force, after all, this was his hidden trump card now, Zhang Yu only used the Boundless Cloud Hand!

When Zhang Yu used the Boundless Cloud Hand in the past, the 罡氣 could only cover a range of a few meters!

But at this moment, after merging with the Qi Sea Spirit Root and entering the Foundation Establishment realm, Zhang Yu’s mana limit, mana scheduling efficiency, and output efficiency all far exceeded the limit of Qi Refining!

In the blink of an eye, the Formless Cloud罡 had covered the surrounding battlefield of dozens of meters, like a rising fog!

Zhou Yang was slightly stunned by the sound coming from the fog, and the next moment he saw that the other party had already come stepping on the sea of clouds!

At the same time, the surrounding Formless Cloud罡 had unknowingly attacked, like underwater undercurrents, wrapped around Zhou Yang’s hands and feet, blocking his actions!

Zhang Yu gently slapped Zhou Yang!

Zhou Yang subconsciously took the palm, and activated the Zhou family’s Frost Heaven Freezing Qi field, streams of palm force carrying resentment and corpse cold blasted towards Zhang Yu!

The two palms collided, and with a light bang, Zhou Yang’s expression suddenly changed drastically, only feeling that the other party’s palm seemed inconspicuous, but until he really came into contact, he realized how violent the Formless Cloud罡 contained in it was!

If the freezing Qi he blasted out with a palm was a trickling stream, then the 罡氣 blasted out by the other party’s palm was like a surging river!

The Formless Cloud罡 tore apart the freezing Qi like a ruin, poured into Zhou Yang’s body, exploded his meridians, shattered his bones, and with a series of bangs, Zhou Yang’s left and right arms shattered and exploded into a cloud of blood mist!

After being severely injured by a palm, Zhou Yang fell to the ground, his heart shaking wildly; “Foundation… Foundation Establishment, this is the level of mana output that can only be achieved in the Foundation Establishment realm.”

Zhang Yu treated him like air, silently walked to Bai Zhenzhen’s side, and put her in his arms!

Looking at Bai Zhenzhen’s pale face and the injuries on her body, Zhang Yu said, “Sorry, I’m late!”

Bai Zhenzhen smiled slightly and said, “Isn’t it just right that you came?”

From Zhang Yu’s entry, to severely injuring Zhou Yang with one move, to picking up Bai Zhenzhen, it was only a matter of a few seconds!

In these few seconds, the many Qi Refining experts around did not stop their movements, and had already rushed into the thick fog, attacking towards the direction where Bai Zhenzhen was in their memory!

Facing the siege of more than a dozen Qi Refining peaks, Zhang Yu held Bai Zhenzhen in one hand, and slightly exerted his strength with the other palm, and then blasted out with a palm across the air!

If it was said that just now, in order to seek speed and rescue Bai Zhenzhen first, Zhang Yu just used a normal attack against Zhou Yang!

Then at this moment, Zhang Yu also stacked the Back Dragon Turning Mountain Hand and the Dragon Elephant Collapsing Mountain Palm’s force application techniques in one palm!

Although these two are only Qi Refining stage martial arts, but at this moment, under the blessing of Zhang Yu’s Foundation Establishment mana and martial arts holy body, they burst out with unprecedentedly fierce palm force!

Everyone only felt a crackling explosion in the air, and then it seemed that the roar of a dragon elephant was heard!

Ye Mantian only felt that a giant dragon in this sea of clouds roared and crashed into him, he burst out with all his strength, and fought with both palms, but he was still shattered at the first touch, and flew out with a bang, crashing into a small building!

Ye Mantian barely stood up, but suddenly spat out a large mouthful of blood, only feeling that his internal organs were cracked and his bones were broken, and he knelt down on the ground with a bang!

When he looked up, he saw that the extremely thick fog just now had been dispersed by the wind caused by the explosion, revealing a scene like a big explosion!

And the many experts who were fighting bravely just now, none of them could still stand!

Some crashed into the broken walls, only revealing part of their bodies!

Some fell to the ground covered in blood, already losing consciousness!

Some were only left with broken limbs, and no longer had complete bodies!

And Ye Mantian looked at Zhang Yu standing in the center of the battlefield, holding Bai Zhenzhen in one hand, and said bitterly in his heart: “Foundation Establishment…”

At the same time, streams of divine power descended from the sky, and the surgery talisman launched by Wang Yuancheng had begun to treat Chi He, Ye Mantian and others!

But even feeling the injuries on their bodies recovering rapidly, whether it was Chi He or Ye Mantian, the many experts present were cold in their hearts, and did not dare to move at all, let alone show any fighting spirit or hostility!

Because they read the same message from Zhang Yu’s cold eyes!

Whoever moves, dies!
