These three days, Situ and his son constantly discussed alchemy with Zi Lingling, making Ye Lingyuan's face darken repeatedly.
However, with Situ Jinglei, an elder, present, the prince couldn't openly express his displeasure and could only watch his wife being entangled by the two in the alchemy chamber.
Situ and his son benefited greatly, their alchemy skills both saw significant improvements.
Situ Yunfeng touched the barrier of an intermediate alchemist, and with diligent practice, breakthrough was within reach.
Situ Jinglei also gained deeper insights into advanced alchemy and was rapidly advancing towards becoming a master alchemist.
Moreover, after these three days of interaction, Situ Jinglei felt that Zi Lingling suited his taste so well that he even planned to directly apprentice under her, but Zi Lingling refused.
This was why the two of them were so insistent on keeping Zi Lingling.
However, firstly, Zi Lingling had to deal with matters at the border. Even without Ye Moyuan's coercion, she had to meet the people of the Zi family of the Empire.
The Zi family of the Empire instigating the Jin Xia Kingdom to advance towards the border of the two countries had touched Zi Lingling's bottom line.
Because once war erupted, it would involve innocent civilians.
The Zi family of the Empire, for the sake of just one person, Zi Lingling, disregarded thousands of lives, which was something Zi Lingling could not tolerate.
She had her principles: "You can come for me, but do not involve the innocent."
Therefore, no matter what, this trip to the border was imperative for her.
Secondly, the prince had reached his limit of tolerance. If they continued to stay at Medicine King Valley, Ye Lingyuan would explode.
If the Underworld King's Highness could no longer bear it, things would become serious.
In short, to sum it up, Zi Lingling had to quickly leave Medicine King Valley and continue her journey towards the border.
Situ Jinglei also knew Zi Lingling's mind was made up, and further persuasion was useless, so he could only say, "Girl Zi, if you need anything, Medicine King Valley is at your service anytime!"
Situ Yunfeng also cautioned, "Girl Zi, A Yuan, if the people of the Zi family of the Empire are truly unreasonable, tell me, and I'll find something for them to do. Anyway, other families in the Azure Dragon Empire, White Tiger Empire, Vermillion Bird Empire, and Black Tortoise Empire are not doing anything!"
Zi Lingling chuckled, "Situ, I only discovered today that you're so sly! Regardless, thank you and Uncle for your kindness. Don't worry, I don't put them in my eyes."
"Alright, a thousand-mile send-off must still end. It's getting late, and we should be leaving too! Take care!"
Situ Jinglei and Situ Yunfeng clasped their fists and said, "Have a safe journey!"
"With this King here, you can rest assured!"
Ye Lingyuan smiled, put his arm around Zi Lingling's waist, and got into the carriage.
"Depart!"
With Qing Feng's order, the convoy began to move.
Situ Jinglei and Situ Yunfeng watched until everyone disappeared from sight before turning to walk back to Medicine King Valley.
"You brat, you say Girl Zi is such a good girl, why haven't you managed to win her over!"
"Old man, don't just talk about me. Didn't you also shamelessly try to apprentice under her and get rejected?"
"Brat, what do you mean shamelessly? In the path of cultivation, the capable are teachers! Although she and I are both advanced alchemists, her knowledge far surpasses mine."
"Moreover, I have a premonition that Girl Zi will definitely break the shackles of the Heavenly Origin Continent and advance to the rank of a divine alchemist!"
Situ Yunfeng was stunned. It was the first time he had heard his old man give such a high evaluation of someone.
"Old man, you're right! Girl Zi and A Yuan are a pair of monsters. I wouldn't be surprised by any achievements they make!"
"No, they aren't monsters, they are monsters among monsters!"
"Alright, alright! Old man, stop waxing poetic here. Let's go, let's go! Hurry home and refine alchemy, don't delay Girl Zi's important business!"
"Brat, after eighteen years, you've finally said something sensible! You're right, we mustn't delay Girl Zi's important business!"
"Hey, old man, wait for me!"
"Brat, you go slowly, I'm leaving first."
...
On the wide road, a group of people was advancing rapidly.
Upon closer inspection, the people in this group all carried a killing aura, as if they had emerged from death.
"Ying Hu, we were not unfairly defeated back then. Not to mention our leader's own terrifying combat power, just her relationship with the Underworld King, if she wanted to use the Underworld King's hand to destroy us, it would have been as simple as lifting a finger."
"Who said it wasn't! Ru Yi, I am very fortunate now that we didn't resist stubbornly. Although the Iron Blood Mercenary Group is gone, the passionate days will not end. I believe that under the leader's guidance, our King's Mercenary Group will surely have a day to reign supreme."
These two were indeed Tie Yinghu, the former leader of the Iron Blood Mercenary Group, and Xue Ruyi, the former deputy leader. Now, they were the leaders of the King's Spear.
For this expedition, Zi Lingling only brought out the King's Spear and the King's Wings. The King's Shield and King's Heart were left at the post in Xianhe Town.
Her main purpose was deterrence, and all the members of the King's Spear and King's Wings were spiritual practitioners above the Qi Gathering realm, which would surely make the other party wary.
Furthermore, mercenaries lived a life of licking blood from the tip of a knife. Compared to armies, their killing intent was heavier. Now, after being trained by Mu Qingyan, they had become an invincible battle spear.
Therefore, although the King's Spear and King's Wings were not numerous, totaling no more than three hundred people, if paired with the formations taught by Mu Qingyan, they were definitely capable of fighting one against a hundred.
The reason Zi Lingling brought them out this time was twofold: first, to allow them to familiarize themselves with formations and deter the Jin Xia Kingdom; second, many of them had just broken through and needed a battle to solidify their strength.
"Ying Hu, President Zi is no ordinary person. Following her, we are not at a loss. But similarly, there will be no shortage of fighting and killing in the future. I worry that one day we might end up..."
Xue Ruyi's eyes were filled with deep worry.
She was just a weak woman. If it weren't for survival, she would only want to be together with her beloved man, never to be separated!
However, the man in her eyes was currently full of heroic spirit, eagerly preparing to make a grand effort.
This was no one's fault. A woman only needed to conquer a man, but a man's goal was always to conquer the world and stand at a height unreachable by others.
"Ru Yi, the moment we decided to become mercenaries, we had already cast aside life and death. Therefore, your worries are unnecessary. If that moment truly comes, it will be the time of infinite glory for us mercenaries!"
Tie Yinghu looked at Xue Ruyi tenderly, but his heroic aura overshadowed the affections of a young couple.
"Ru Yi, President Zi has shown us great favor. Not to mention anything else, just the elixirs she unhesitatingly produced are favors we can never repay."
