Fang Yuan stood outside the entrance of the Legacy for an entire day. After seeing that no more Strength Path Gu Masters were entering, he handed over control of the body to Yuan Fang.
Yuan Fang looked around the entrance a few more times, gave some instructions to the surrounding Elders of the Family, and then stepped into the Dog King Legacy.
The Dog King Legacy was filled with numerous trials, each level testing a Gu Master's Servitude Path attainment.
Because of Fang Yuan, Yuan Fang was already a Servitude Path Great Master. He broke through the trials all the way from the first level to the thirtieth level before stopping, reaping significant rewards.
After taking a brief rest, Yuan Fang stepped into the Letter King Legacy.
The Letter King specialized in Information Path while also cultivating Refinement Path. His Legacy tested the successor's Refinement Path attainment and Gu Refining techniques. Compared to Servitude Path, Yuan Fang and Fang Yuan were inherently more skilled in Refinement Path; thus, the Letter King Legacy was naturally easy for him, and he advanced with irresistible force.
After passing fifty levels of the Letter King Legacy, Yuan Fang turned and entered the Blast King Legacy.
Inside the Blast King Legacy, he deliberately did not fight back, allowing the Egg People within the Legacy to attack him until he was heavily injured and on the verge of death, at which point he was teleported into the Tyrant Tortoise Legacy.
Inside a grand hall, a giant tortoise appeared old and frail; it was the Tyrant Tortoise Earth Spirit, whose life was nearing its end. Upon seeing Yuan Fang, its face was filled with excitement, as if it had waited for countless ages and finally met an old friend.
Yuan Fang had just climbed up from the ground under the treatment of the Tyrant Tortoise Earth Spirit. Just as the Tyrant Tortoise Earth Spirit was about to speak, it was directly interrupted:
"Tyrant Tortoise, you don't need to introduce yourself. The Legacy trial is to refine the second aperture gu, right?"
The Tyrant Tortoise Earth Spirit was slightly startled and was about to speak when, in the next moment, an incredibly powerful aura suddenly leaked from Yuan Fang's body, shocking it so much that its voice began to tremble:
"You... young man, this is actually... actually the aura of an immortal gu! This... this seems to be..."
"It's the spring autumn cicada from the Ten Great Ancient Gu List! How did a mere Mortal like you obtain this Gu!"
Yuan Fang, however, did not blush or pant, and his eyes did not even blink as he lied, responding in a deep voice:
"Tyrant Tortoise, the spring autumn cicada has the power to reverse time. I am a future Gu Immortal and also your future master."
The Earth Spirit's mind was inherently simple; how could it have imagined it had fallen into a trap? It could only cry out in shock repeatedly:
"Young man! Is everything you said true? You actually truly refined the second aperture gu! Indeed, that is a future Gu Immortal, possessing the spring autumn cicada. It seems I have finally completed my mission of waiting..."
Before it could finish its sentence, the Tyrant Tortoise Earth Spirit's eyes turned red, clearly moved to the extreme.
Yuan Fang quickly spoke to soothe it: "Tyrant Tortoise, do not lose your composure. Since I am a future Gu Immortal, I know that this moment is fraught with danger and time is of the essence. There is very little green grape immortal essence left in this blessed land, isn't there? By the way, is there a heaven connecting gu here?"
His face was full of anxiety, and the Tyrant Tortoise Earth Spirit, infected by his expression, also became flustered and nodded repeatedly: "Yes, yes, yes!"
The heaven connecting gu is a Rank Five Gu. Activating this Gu allows one to communicate with Treasure Yellow Heaven. Treasure Yellow Heaven is a trading market between Gu Immortals, where the circulating currency is not mundane primeval stones, but immortal essence stones.
Everything sold there consists of immortal materials, and even Rank Five Mortal Gu can be purchased in batches.
A moment later, the Tyrant Tortoise Earth Spirit brought the heaven connecting gu.
Yuan Fang immediately activated the Gu worm to communicate with Treasure Yellow Heaven and, with a flick of his hand, posted fifty percent of the blood god child immortal gu recipe.
The blood god child was originally a rank six immortal gu. During Fang Yuan's five hundred years in his previous life, he had originally intended to refine this blood god child instead of the spring autumn cicada, but due to the trickery of Heaven's Will, he mistakenly obtained the immortal gu recipe for the spring autumn cicada and eventually refined it instead.
"What! It's actually fifty percent of the blood god child immortal gu recipe!" A Gu Immortal caught sight of this scene and immediately asked Yuan Fang how many immortal essence stones he wanted, but Yuan Fang turned a deaf ear.
This behavior quickly attracted the attention of several Gu Immortals. Everyone immediately competed to bid, and when the price rose from ten immortal essence stones all the way to thirty-eight, Yuan Fang finally relented and agreed.
This scene made even the Tyrant Tortoise Earth Spirit watch with great excitement—one immortal essence stone could be converted into one bead of green grape immortal essence, and because of years of consumption, this blessed land now had only a dozen beads of green grape immortal essence left.
Yuan Fang took out the bright moon still water tower from his aperture; Fang Zheng, Clan Leader, and Qing Shu were all inside. He sent out Purple Gold Relic Gu, instantly causing the cultivations of Fang Zheng, Clan Leader, and Qing Shu to soar to Rank Five Peak.
Subsequently, Yuan Fang ordered Qing Shu, Clan Leader, and Fang Zheng to enter the Three Kings Legacy. With the assistance of the Tyrant Tortoise Earth Spirit, the three of them broke through the levels with irresistible force, making progress easily and smoothly.
Yuan Fang then instructed the Tyrant Tortoise to first exchange ten immortal essence stones for green grape immortal essence, while he handed control of the body back to Fang Yuan, so that Fang Yuan could begin refining the second aperture gu.
During the period of Gu Refining, Fang Yuan used the Tyrant Tortoise's help to eliminate Tie Mu Bai, Long Qing Tian, and others, and used slave gu to enslave Qiu Jiu and Feng Tianyu.
He used Qiu Jiu to incite a war between the Righteous Path and the Demonic Path, while Feng Tianyu was a Refinement Path genius who had once refined a Rank Five Gu with a Rank Three cultivation. Fang Yuan kept him by his side to assist in refining the immortal gu.
Not long after, Fang Zheng and the other two obtained the Three Kings' true inheritance and also brought back a crucial Gu worm—none other than the Hundred Battles Unfailing Gu!
This Hundred Battles Unfailing Gu was the Letter King's lifelong masterpiece, and in the original work, it was considered a Heaven-Defying Mortal gu:
Not only could it make a Gu Refining session one hundred percent successful, but even more absurdly, it could achieve one hundred percent success even when refining an immortal gu!
If the Heavenly Court possessed a Hundred Battles Unfailing immortal gu, they would no longer need to rely on the Gu Refinement Convention to accumulate success dao marks; they could simply use this Gu to refine Fate Gu. It was no exaggeration to say it was even more useful than success dao marks.
Since refining the bone flesh reunion gu with Fang Yuan, Fang Zheng had been constantly seeking guidance from Fang Yuan and working hard to learn Refinement Path. Now he was already a Refinement Path Great Master, so he also joined Fang Yuan and Feng Tianyu in Gu Refining, acting as an assistant.
Refining immortal gu inherently consumed green grape immortal essence. In the original work, Fang Yuan had almost exhausted his mind and body for Gu Refining, using primeval stones whenever possible to avoid using green grape immortal essence. But now, the reserves of green grape immortal essence in Fang Yuan's hands were abundant, and he could use them freely.
The three of them immersed themselves in refining the immortal gu. A whole week passed, and they had only refined one-third of it.
Just then, Qiu Jiu suddenly sent a voice transmission to Fang Yuan: "Master, I've run into some trouble on my end. Rank Five experts from the Demonic Path, like Mo Wu Tian and others, have arrived and are questioning me why I won't let everyone enter the Legacy. I really don't know how to respond."
Upon hearing this, Fang Yuan immediately activated an Information Path Gu worm to reply:
"Stall for as long as you can. If you really can't hold out, then let them fight their way in. At that time, you can sow discord among them and reignite the war between the Righteous Path and the Demonic Path."
Qiu Jiu's voice came through again with difficulty: "Lord, this might be hard to manage. A Rank Five Gu Master from the Righteous Path named Xiao Mang has also arrived. This person has already reached an agreement with the other Rank Fives of the Demonic Path and is currently waiting for my answer."
"In that case, act as the situation dictates. Do not touch Xiao Mang for now; he is a key figure, and I will deal with him personally."
Fang Yuan knew clearly in his heart that Xiao Mang held a great light gu in his hands, which was crucial for the subsequent plans.
Just as he finished speaking, an earth-shattering vibration suddenly came from outside the hall, as if the mountains were shaking, causing the entire palace to tremble slightly. Fang Yuan and the other two immediately stepped out of the hall to check the situation.
They saw that on the vast, empty square outside the hall, hundreds of thousands of canine Gu beasts were stationed. There were many types, such as Iron Armor Dogs and Autumn Sword Dogs, and the beast groups stretched for several miles, with no end in sight. The few people leading them were the three Slave Path Gu Masters of the Gu Yue Clan, as well as Gu Yue Qing Shu.
Fang Zheng was overjoyed at the sight: "These hundreds of thousands of dogs are simply a godsend! Even if the people from the Righteous and Demonic Paths attack, they can hold out for a week. Looking at this scale, I'm afraid even Beast Emperor level existences are hidden among them."
Before he could finish, two massive Dog Kings stepped out from the hundreds of thousands of dogs, their Rank Five auras surging—these were already Beast Emperors above the Ten Thousand Beast King level, possessing genuine Rank Five combat power!
Gu Yue Ding Hao, dressed in a blue martial uniform, walked quickly into the hall, bowed to Fang Yuan with his hands clasped, and then reported:
"Reporting to the Clan Chief, among the dog groups brought this time, there are two Beast Emperors, twenty-nine Ten Thousand Beast Kings, two hundred and thirty-seven Thousand Beast Kings, and four thousand one hundred and thirty Hundred Beast Kings. The total number of dogs is two hundred and thirty thousand, all of which are remnants of the former Dog King!"
"Young man, you truly are a future Gu Immortal."
The Tyrant Tortoise Earth Spirit could not hide its joy. In the blink of an eye, the second week passed, and the refining progress of the second aperture gu had reached ninety-nine percent.
Only this last step remained, yet it was the most difficult and arduous stage of the entire Gu Refining process. One wrong step and all previous efforts would be completely wasted.
This final step was to merge the incomplete plate of the second aperture gu with the rank six immortal gu Divine Travel to refine that legendary immortal gu—the second aperture gu.
"Fang Zheng, this next step is no longer something you can help with."
Fang Yuan released the mortal gu house, the bright moon still water tower, his tone carrying an irrepressible exhaustion and weariness. These two weeks of refining immortal gu had almost drained all of his energy and spirit:
"Take it and stand guard for me outside the hall. Do a good job, my brother; the Gu Yue Clan depends on you."
Fang Zheng nodded and took it, feeling secretly moved in his heart, and turned to walk out of the hall. Outside the hall, more than ten thousand Gu Yue Clan Members had already gathered with over three hundred thousand dogs. Their faces were all filled with worry, and seeing Fang Zheng come out, they all bowed in salute:
"We are willing to fight for the Gu Yue Clan and swear to protect the Clan Chief to the death!"
These Gu Yue Clan Members were all brought into the Legacy in recent days by Fang Zheng and the others with the assistance of the Tyrant Tortoise Earth Spirit.
Now that everything was prepared, Fang Yuan tiredly rubbed his temples and began the Gu Refining with Feng Tianyu, pushing through this final step that would determine success or failure.
In just a few minutes, both of them were drenched in sweat.
Just then, an earth-shattering explosion rang out, and the roof of the hall was actually blown open. The entire palace shook violently—the Gu Masters of the Righteous and Demonic Paths had fought their way in.
This sudden impact nearly caused the Gu Refining to fail at the last moment.
Seeing this, the Tyrant Tortoise Earth Spirit hurriedly consumed a bead of green grape immortal essence to set up a barrier, blocking the offensive of the Gu Masters outside the hall, while simultaneously transmitting its voice to Fang Yuan inside:
"Young man! I can only support it for the time it takes half an incense stick to burn! Are you ready on your end?"
Fang Yuan, however, had no time to respond. He gritted his teeth and raced against time to refine the Gu, sweat having long since soaked through his clothes. At this very moment, five people suddenly kicked open the hall doors, and the leader, Tie Ruo Nan, looked on with eyes nearly splitting with rage:
"Fang Yuan! You killed my father. Today I will level this demonic den of yours and make you wish for life but be unable to live, and wish for death but be unable to die!"
Fang Yuan urgently ordered Feng Tianyu to step forward and resist. At this critical moment, an aura originating from the immemorial era suddenly permeated the air, and a brilliant light burst forth—the second aperture gu was refined!
