In the capital city of the Heaven Dou Empire, within the Dugu Mansion, in a forbidden room.

Looking at the antidote for the Jade Scale Serpent's venom that he had concocted based on the letter from the mysterious man named Hao, who claimed to be the young lord of Baicao City.

He took a small sip, savoring the taste for a long time, and finally sighed helplessly.

"Even if I use all my strength, I can only formulate the Jade Phosphorous Serpent venom that is effective against my Soul Master stage. Although Yan Yan's innate soul power is not as high as mine, with me leading the way, she can at least cultivate to the Soul Douluo level."

"With my supervision, once all the spirit rings are chosen to be the best and of the optimal age for the Azure Serpent Martial Soul, and the Soul Master stage begins to unleash its power, it will definitely surpass me slowly. Sigh! I can only watch and wait..."

Exhausted, Dugu Bo ignored his disheveled green hair and walked out of the mansion, heading towards the address left on the letter. But suddenly, his face turned slightly pale, and Dugu Bo groaned as he circulated his soul power. A trickle of black blood spilled from the corner of his mouth, and his soul power surged as he rushed to the Ice and Fire Yin-Yang symbol to suppress the poison in his body.

After Dugu Bo left, the many soul masters who had felt the pressure of the titled Douluo's soul power and had come to investigate because they were in the imperial city, left one after another after confirming that there was no problem here and that it posed no threat to the safety of the Heaven Dou royal family and Emperor Xue Ye.

A dashing and debonair young man in black, exuding an air of wickedness, emerged from the seemingly undisturbed space. He gazed at Dugu Bo, who had already entered the Sunset Forest, and gently closed his folding fan, saying with a hint of helplessness.

"He's still a young man after all! But now it seems that as a person, he's relatively complete, only he's still so naive about everything."

"Without any guarantee whatsoever, you dared to hook such a big fish as Dugu Bo. Did you not expect the danger posed by the old poisoner, or did something else tug at your heartstrings and cause you to lose your composure?"

"I should have known better than to let Xueji go. Now I have to take care of her for the ten most unruly years of her life. I envy that tiger! He has his parents to keep an eye on him, and he can just watch from afar. Sigh..."

As the words faded, the figure that had suddenly appeared vanished completely, leaving no trace in this world.

At this moment, Dugu Bo, who had rushed to the Ice and Fire Yin-Yang Well with all his might and barely managed to suppress the deadly poison in his body by using the ice and fire energy here, began to yearn for the mysterious person who should really be the young city lord of Baicao City.

After all, he knew where the real Hundred Herbs City was, and as for the medical skills of Hundred Herbs City? Well, let's just say that the pharmacists couldn't save the people he wanted to kill, and tragically, he himself was one of them.

As for the idea that the apparent young city lord was Lin Wushuang, who had a great reputation in the world of pharmacists, he never even considered going to Baicao City to see what was going on.

Rewind a few hours, and dawn is approaching, the sun is rising.

The biological clocks that had been developed day after day over the years woke the two of them up.

Lin Hao, who had barely managed to refrain from doing anything last night with great willpower, looked at the eyes that were still slightly misty and staring straight at him.

Seeing the obvious hole, knowing that Yang Rui probably hadn't fully recovered, he naturally withdrew his hand, stood up, and straightened his slightly disheveled clothes.

After tidying herself up, she also tidied up Yang Rui, then pulled the blanket up a bit to keep the girl warm. She then walked out of the house, leaped onto the roof, and silently began circulating her inner soul power according to the familiar Qi circulation route, continuously strengthening her physical body and soul.

After confirming that Lin Hao had left the house, Yang Rui, who had been lying in bed as if he hadn't woken up yet, turned around and lay down, letting out cute little whimpers.

After a long while, she calmly and naturally crawled out of the quilt, tidied her clothes and appearance which she had messed up again, and quickly walked out of the room. She also jumped onto the roof and naturally began to practice the basic Qi cultivation technique with Lin Hao.

This was taught to her by Lin Hao after she broke through to level 20, the Quasi-Great Soul Master. Of course, she didn't intend to teach this kind of soul power meditation method to anyone except her future child. After all, even if she hadn't thought about it at the time, she had already been convinced and accepted it.

And now...

Her breathing had just become a little rapid when something tapped her forehead, jolting her out of her meditative state.

He opened his eyes in confusion and saw Lin Hao lower his hand that he had just raised.

If you can't calm your mind, then stop cultivating for now and postpone this period. Summon your martial spirit in the courtyard now; you should know what to do.

"oh."

She responded softly, and all I can say is that women are all perfectly talented actors! Especially after discovering that some members of the Power Clan had also come out of their rooms and begun their daily, consistent training.

Upon discovering that she and Lin Hao were not alone, Yang Rui, with a cold expression, agreed and jumped down, summoning his martial spirit and holding it in his hand. He then assumed a horse stance, closed his eyes, and began to take long, deep breaths.

Looking at Yang Rui, who had regained his calm demeanor, Lin Hao, whose thoughts were slightly disturbed, also gave up his cultivation and continued to sit cross-legged on the roof, calming his mind and spirit.

As everything proceeded as usual, Lin Hao, who had temporarily accomplished one of his ideas, silently took out a book in the courtyard and began reading and making notes.

Meanwhile, Yang Rui was practicing basic marksmanship at the other end of the courtyard, constantly familiarizing himself with his martial spirit.

The perfect harmony of quiet and noise, stillness and movement, creates a natural beauty. Dugu Bo, who should have arrived much earlier, also suppressed his aura and stood behind Lin Hao, seeing the words Lin Hao was writing.

Martial Soul Research, First Draft (Most of the unproven aspects are merely personal speculation.)

First, the quality of a martial soul is directly proportional to its innate soul power (this is largely accurate, but there are still some exceptions, so it remains questionable).

Second, the mutation of a martial soul can be divided into innate and acquired factors. Most of the acquired factors come from the soul rings obtained by hunting soul beasts, the environment in which one lives for a long time, and the food consumed over a long period of time, etc.

Looking at the densely packed notes and some data based on the writer himself, Dugu Bo, who only knew how to play with poison, silently swallowed.

To be honest, when he first arrived, he thought the mysterious person was playing a trick on him. After all, there were only two little kids under 12 years old in the whole yard. If this wasn't a joke, what else could it be?

But after sensing the girl's chilling aura and pure spear intent, seeing the very obvious Soul-Breaking Spear, and recognizing that the girl possessed at least level 24 or higher of soul power and was under 12 years old, Dugu Bo realized that he had been too superficial.

Then, he turned his gaze to Lin Hao, whom he couldn't quite understand, and then he knew who the mysterious person who wrote the letter to him was, and who the person who had cracked his Jade Scale Serpent Emperor Poison was!
