"I still need to increase the foundation of my Soul, otherwise, absorbing more Gu Master memories will be too much to handle," Liu Chen murmured to himself.
He had just experienced Ou Ye's true memory Legacy and deeply felt the immense pressure on his Soul.
Since he left Gu Yue Village, he had received several Legacies, and the memories within them were intricate and tangled, placing a heavy burden on his Soul.
If he didn't promptly enhance his Soul foundation, he feared he wouldn't be able to endure more memories, let alone further improve his strength.
"It's a pity about Fox Immortal Blessed Land, and that Guts Gu," Liu Chen sighed, secretly regretting it.
Guts Gu was known as the top choice for strengthening the Soul, its effect being absolutely superb.
However, he couldn't claim it for himself, which was truly regrettable.
Nevertheless, Liu Chen was not disheartened by this.
He quickly adjusted his mindset and began to consider other feasible methods for strengthening his Soul.
After all, there are always more solutions than problems; as long as he put his mind to it, he would find a way to solve the problem.
After much deliberation, Liu Chen thought of several methods to strengthen his Soul.
However, these methods either required a huge price or yielded minimal results, which was somewhat frustrating.
But Liu Chen was not intimidated by these difficulties; he decided to act immediately.
Without hesitation, he took out the Living Treasure Window from his System backpack.
"Master~" As soon as Living Treasure Window saw Liu Chen, he immediately clung to him, tears streaming down his face as usual, looking as if he had suffered an immense grievance.
Liu Chen felt a wave of helplessness at this sight.
Every time he faced Living Treasure Window's reaction, he could only comfort him gently, and it would take a while for him to calm down.
After appeasing Living Treasure Window, Liu Chen looked at the bucket of Gu material spring water he had just acquired.
After a short rest, Liu Chen finally stated his true needs: "This time, I need Coptis Gu, Five Labors Gu, Starving Gu, Empty Gu, Chaotic God Gu, and ten Sword Soul Gu, as well as two portions of Immortal Wind Gu, Star Gu, and those Gu materials."
Upon hearing this, Living Treasure Window immediately perked up.
He quickly contacted the Treasure Realm and, after communicating, reported to Liu Chen: "Master, all the Gu you mentioned can be found in the Treasure Realm.
However, I need you to provide two Four-Turn Gu and thirty-eight Third Rank Gu as exchange."
Liu Chen agreed without hesitation: "No problem!"
He then selected the required Gu from his collection and handed them to Living Treasure Window.
Living Treasure Window happily accepted these Gu, then swallowed them without hesitation.
Immediately after, Living Treasure Window opened his mouth and spat out all the various Gu and Gu materials Liu Chen needed, one by one.
Liu Chen carefully collected these Gu and then refined them one by one.
He first chose to refine a Fixed Immortal Travel Gu, a Gu that could save his life at critical moments, and the most important part of his plan.
Refining Fixed Immortal Travel was already Liu Chen's most familiar task, and having received Ou Ye's true Legacy had also elevated his Refinement Path Realm to the quasi-Great Grandmaster level.
After a meticulous refinement, Liu Chen successfully refined the Fixed Immortal Travel Gu.
He carefully put this Gu away for future use.
He had actually refined two Fixed Immortal Travel Gu consecutively, which greatly improved his mood.
Next, Liu Chen took out a Second Rank Time Gu.
He set a one-year countdown, preparing to use this time to enhance his Soul foundation here.
After all, the strength of his Soul was crucial to him, determining whether he could quickly improve his own strength.
With Fixed Immortal Travel finally refined, Liu Chen immediately decided to first strengthen his Soul foundation right here.
Liu Chen carefully took out a strangely shaped grass Gu from his Pregnant, this Gu was like a chicken's claw, entirely yellow, emitting a faint herbal fragrance.
This was the legendary Coptis Gu, which, although it could enhance a Gu Master's Soul foundation, came at an extremely severe cost.
Once Coptis Gu was activated, any food the Gu Master ate thereafter would taste like the utmost bitterness in the human world, and they would never be able to taste other flavors again.
However, to Liu Chen, who was determined to become stronger, what did this amount to?
He unhesitatingly activated Coptis Gu, and the Gu instantly transformed into a yellow energy, like a clear spring, pouring into his Soul.
This energy seemed to have a life of its own, flowing through Liu Chen's Soul, nourishing his Soul.
As the energy of Coptis Gu was absorbed, Liu Chen clearly felt his Soul becoming stronger.
The original heavy burden instantly lightened, and his thoughts became exceptionally clear, as if the earth had been washed by a spring rain, completely refreshed.
However, the side effects were equally obvious.
Even without eating, an unbearable, extreme bitterness still lingered in Liu Chen's mouth.
This bitterness not only stimulated his taste buds but also made his throat feel as if it were burning.
Even simple actions like swallowing saliva became a form of torture.
But Liu Chen remained expressionless; he clenched his teeth tightly, silently enduring it all.
To become stronger, he was willing to pay such a price.
The effect of Coptis Gu was most significant during its initial use, greatly enhancing the Soul foundation.
However, once this initial stage passed, its effect would gradually weaken, and subsequent improvements could only rely on slow, painstaking effort, using the side effects of Coptis Gu (enduring bitterness) to temper one's Soul.
Liu Chen, enduring the bitter taste in his mouth, unhesitatingly took out another five-pointed Gu.
This Gu was named Five Labors Gu, and its effect was quite similar to Coptis Gu, both capable of effectively enhancing the Soul foundation.
However, the side effects of Five Labors Gu were also obvious; it would make the Gu Master's body's Qi, blood, flesh, bones, tendons, and all other aspects feel utterly exhausted, making the Gu Master appear sickly.
But Liu Chen was not afraid of this; to enhance his Soul foundation, he was willing to pay any price.
Moreover, Liu Chen was not without a countermeasure.
He knew that the timing for removing these side effects was crucial; if done too early, it would fail to achieve the effect of enhancing the Soul foundation.
Therefore, he specifically set a one-year cultivation period to ensure that the side effects were removed at the appropriate time, thereby maximizing the efficacy of Five Labors Gu.
With the activation of Five Labors Gu, Liu Chen clearly felt his Soul expanding, like a deflated balloon slowly being inflated, gradually becoming full.
However, at the same time, a strong sense of fatigue spread throughout his body; this fatigue emanated from his entire body's Qi, blood, bones, flesh, and tendons, from the inside out.
Every movement he made became extremely difficult, as if his body no longer belonged to him, and every gesture was filled with a heavy weariness.
His steps became faltering, like an old man in his twilight years, needing to exert all his strength with every step.
