Nanjiafu fell into a panic because the three of Nanyun Mountain were suspected of offending a Daozun realm master, and Yun Tianyu returned home, and after reporting safety to Nan Hongpeng, who had improved a lot, he immediately returned to his house, preparing to take the True Yuan Pill to break through the realm.

"Great Demon King, now that there are more than five months left before the competition of the younger generation in the clan, you start to help me refine the pill, I want to use the True Yuan Pill to impact the realm of the fourth-level Daoist. After closing the door, Yun Tianyu called the Great Demon King with his heart.

"You take out all the medicinal materials you purchased this time, and I will help you refine some auxiliary potions to help you completely absorb the medicinal power of the True Yuan Pill and impact the realm of a fourth-level Daoist. The Great Demon King emerged from the space-time dream and commanded.

"Thank you!" Yun Tianyu nodded, and took out a large number of precious medicinal materials of not low years that he had spent more than five thousand spirit stones to buy in his baggage, and handed them all over to the Great Demon King.

"Tianyu, when I refine the auxiliary potion, you pay attention to it, it will be good for your future growth. After releasing a black flame to devour the several herbs handed over by Yun Tianyu, the Great Demon King admonished.

"Okay!" Yun Tianyu nodded, concentrating his gaze on the several medicinal herbs that were engulfed by the black flames and quickly melted.

Looking at the Great Demon King's precise fire control ability, skillful refining methods, and flawless alchemy techniques, Yun Tianyu's eyes were deeply attracted, and he couldn't extricate himself from it.

For about half an hour, a large amount of fiery red liquid appeared in the scorching black flame, and under the refining of the black flame, it became more and more refined.

When a large amount of fiery red liquid condensed into eight drops, a scorching black flame flowed out of the Great Demon King's palm.

"Tian Yu, when you take these eight drops of fiery red liquid, you have to be fully mentally prepared, your meridians are likely to be stretched apart by the True Yuan Pill and the True Yuan released by these eight drops of fiery red liquid, it may be very painful at that time, if you can't bear it, not only will you not be able to break through, but you will also waste the medicinal power of the True Yuan Pill, don't let me down." The Great Demon King said in a deep voice.

"Don't worry, Great Demon King, the pain won't knock me down. "Over the years, the killer career has greatly honed Yun Tianyu's will, and for the ** pain, Yun Tianyu believes that he will be able to withstand it.

"Okay, let's get started, open our mouths. Seeing Yun Tianyu's resolute eyes, the Great Demon King nodded slightly, and controlled the several drops of red essence liquid he had refined to flow into his body along Yun Tianyu's slightly open mouth.

When the fiery red essence liquid entered Yun Tianyu's belly, Yun Tianyu immediately felt as if a scorching flame was burning in his body, and streams of heat flowed along the criss-crossing meridians, and soon flowed all over his body.

As the fiery red essence liquid completely fused with Yun Tianyu's body, Yun Tianyu felt that his body's absorption ability was constantly stimulated, and immediately took out the True Yuan Pill and swallowed it in his stomach.

When the True Yuan Pill rolled into Yun Tianyu's body and formed a large amount of True Qi, it immediately blended with the True Qi released by the fiery red liquid.

A large amount of true qi appeared, and the meridians of Yun Tianyu's whole body began to be expanded little by little, and a feeling of swelling and pain came out of his body.

The true qi in Yun Tianyu's body was like a surging tide, surging wildly, and he immediately ran the Origin Space-Time Technique at high speed, and with the help of the medicinal power of the True Yuan Pill, he constantly impacted the realm of a third-level Dao Master.

As the true qi released by the True Yuan Pill was continuously refined by the Origin Space-Time Technique, the number of Spiritual Qi Origin Particles in Yun Tianyu's heart veins continued to increase.

When the number of Spiritual Qi Origin Particles in Yun Tianyu's heart vein reached two hundred, Yun Tianyu's cultivation of the Origin Space-Time Technique immediately advanced, reaching the second turn of the Spirit Source, and condensing the third true element in Yun Tianyu's heart vein.

The third true element was formed, and the bottleneck of the third-level Dao Master realm was immediately loosened, and under the impact of two hundred spiritual energy origin particles and the three true elements several times, Yun Tianyu successfully broke through the bottleneck and reached the third-level Dao Dao Master realm, and the longevity of the body immediately increased.

Successfully breaking through to the realm of a third-level Dao Master, the Great Demon King immediately fused the refined eighteen drops of red fiery liquid into Yun Tianyu's body, exacerbating the pain in Yun Tianyu's meridians.

As more and more true qi was released by eighteen drops of fiery red liquid, the criss-crossing meridians in Yun Tianyu's body swelled up extremely, and the subtle cracks on the surface of the meridians were forcibly opened, and under the torture of the huge pain, Yun Tianyu's face turned pale.

"Persistence!" Suffering from the inhuman pain, Yun Tianyu took a deep breath, relying on the perseverance he had honed over the years, he persevered in his heart, and operated the Origin Space-Time Technique at high speed to refine the surging true qi in his body, and quickly condensed the Spiritual Qi Origin Particles.

"Click, click!" Under the refining of the Origin Space-Time Technique, the Spiritual Qi Origin Particles that had absorbed enough True Yuan Pill and the fiery red liquid medicinal power began to split, forming new Origin Particles one after another.

As the number of aura origin particles in Yun Tianyu's heart veins continued to increase, the fourth true element gradually formed in Yun Tianyu's heart veins.

The fourth True Yuan condensed little by little, and the medicinal power of the True Yuan Pill that had swelled all over Yun Tianyu's whole body was gradually absorbed, and the meridians slowly returned to normal.

The pain in the meridians disappeared, and Yun Tianyu breathed a long sigh of relief, constantly operating the Origin Space-Time Technique, splitting the Spiritual Qi Origin Particles, and condensing the Fourth True Element.

After about ten days or so, Yun Tianyu operated the Origin Space-Time Technique, and after refining all the medicinal power of the True Yuan Pill, the number of Spiritual Qi Origin Particles in his body reached three hundred, and the fourth True Yuan was condensed in Yun Tianyu's heart vein.

After the formation of the fourth true element, the bottleneck that was difficult for others to break through was immediately loosened, and Yun Tianyu didn't take much effort to break through the bottleneck and reach the realm of a fourth-level Dao master, and his own longevity was also increased from two hundred years old to two hundred and fifty years old.

However, although the realm has broken through, Yun Tianyu's cultivation of the Origin Space-Time Technique has not advanced, which makes Yun Tianyu somewhat regretful.

"Finally broke through. Breaking through the realm, Yun Tianyu, who was suffering from pain, immediately felt that his strength had increased more than ten times, and a slight smile appeared on his thin face.

"Tianyu, don't be too happy first, although you have continuously broken through the realm with the help of the Dao Li Dan and the spiritual liquid refined by me, reaching the fourth level Dao Master, but your realm breakthrough is too fast, which will inevitably cause the realm to be unstable. During this period of your cultivation, I helped you refine a bottle of spiritual liquid, and during this time, you take this bottle of spiritual liquid and use the Origin Time and Space Technique to consolidate the realm of a fourth-level Daoist, so as not to cause trouble to your future strength improvement due to the instability of the realm. The Great Demon King looked at Yun Tianyu with excitement on his face, and handed over a bottle of spiritual liquid he had refined to Yun Tianyu.

"Thank you!" Yun Tianyu took the spiritual liquid handed by the Great Demon King and said gratefully.

"Tianyu, don't waste time, quickly take the spiritual liquid to consolidate the realm. The Great Demon King urged.

"Okay!" Yun Tianyu nodded, took a small sip of the spiritual liquid refined by the Great Demon King, and used the Origin Space-Time Technique to refine the spiritual liquid, consolidating the realm of a fourth-level Daoist.

The spiritual liquid refined by the Great Demon King could not only accelerate the consolidation of Yun Tianyu's realm, but also replenish the energy he needed every day, making Yun Tianyu consolidate for more than twenty days in a row, without a trace of hunger.

Just when Yun Tianyu drank all the consolidation spiritual liquid refined by the Great Demon King and basically consolidated his own realm, he found that Yun Tianyu had locked himself in the house and had not eaten or drunk for more than 30 days, Nan Hongpeng, who was a little uneasy, came to Yun Tianyu's room.

"Tianyu, your master is here, I'm back to the space-time dream, remember, don't tell anyone about my existence. The Great Demon King with keen perception sensed the appearance of Nan Hongpeng's breath, admonished, and immediately returned to the space-time dream to hide.

"Tianyu, are you in the house?" Because Yun Tianyu used the space-time dream to cover the aura emanating from his body, Nan Hongpeng did not feel Yun Tianyu's breath outside the house, his brows furrowed slightly, and he shouted softly.

"Master, I'm here!" Yun Tianyu stopped consolidating his realm, quickly got out of bed and opened the door, and welcomed Nan Hongpeng, who had improved his complexion a lot, into the room.

Just when Nan Hongpeng was shocked by Yun Tianyu's ability to restrain his breath, although he lost his strength, Nan Hongpeng, who still had a keen perception, was completely stunned like a sculpture when he saw Yun Tianyu for the first time, his eyes widened, and his face was full of incredulity.

"Master, what's wrong with you?" Seeing Nan Hongpeng's stunned appearance, Yun Tianyu knew that Nan Hongpeng felt the strength of his fourth-level Daoist realm, and the corners of his mouth turned up slightly, revealing a hint of a smile and said.

"Tianyu, have you reached the realm of a fourth-level Daoist?" Sensing Yun Tianyu's true strength, Nan Hongpeng took a deep breath, trying to suppress the shock in his heart, and asked weakly.

"Well, after more than a month of hard cultivation, I have just broken through to the realm of a fourth-level Dao Master. Yun Tianyu nodded lightly, not hiding his true strength.

"Tianyu, how can your cultivation speed have increased so quickly in the recent period?" Nan Hongpeng looked at the apprentice who made him feel shocked and asked softly.

"Because Nanyun Mountain gave me a True Yuan Pill, with the help of the medicinal power of the True Yuan Pill, I broke through the realm in a row and reached the fourth level of Dao Master. Yun Tianyu said with a faint smile.

"Nanyun Mountain gave you a True Yuan Pill, would he be so kind?" Nan Hongpeng, who knew Nanyun Mountain very well, widened his eyes and asked with some disbelief.

"As for the reason, please allow me to keep it a secret. Yun Tianyu blinked deliberately and said mysteriously.

"Okay then, Tianyu, although you have continuously broken through the realm with the help of the True Yuan Pill, but in the recent period, you had better consolidate the realm, and wait for the realm to be consolidated before continuing to cultivate. Nan Hongpeng felt that it was definitely not simple for Nanyun Mountain to send Yun Tianyu True Yuan Dan, but Nan Hongpeng did not continue to ask, and whispered.

"It's the master. Yun Tianyu nodded lightly and said in response.
