“What… what kind of technique is this?” Even Dongfang Bai was stunned by the exaggerated power of Zhang Weihao, who held lightning in his hand and pierced through a human-shaped sandbag with a single palm strike.

　　He hurriedly asked his younger sister what kind of unparalleled divine skill this was.

　　”This is Young Master’s Palm Thunder. It’s Yu Yan here. Honestly, she came without even saying hello, and just secretly ran off to find Young Master.” After Xue Qianxun discovered it was Jiang Yu Yan, she complained somewhat coquettishly about Jiang Yu Yan’s lack of loyalty and her indifference to men.

　　”Palm Thunder… He can do that too…” For some reason, Dongfang Bai thought of his master’s version of the Dugu Nine Swords.

　　Feng Qingyang’s Dugu Qiubai, or rather Tang Zichen’s Dugu Nine Swords, is different. Tang Zichen’s Dugu Qiubai is not some broken sword style, but the movie version of Dugu Nine Swords.

　　Her version of the Dugu Nine Swords is divided into nine forms: wind, rain, thunder, lightning, clouds, fog, frost, and snow. Practicing this sword technique can change the weather and climate. The more you practice it, the more powerful it becomes, capable of changing the color of the wind and clouds and causing thunder and lightning.

　　Of course, that is a strange phenomenon that occurs after a Grandmaster of the Innate Realm communicates with Heaven and Earth and can borrow the power of Heaven and Earth. It is also the most terrifying aspect of a Grandmaster of the Innate Realm.

　　So Dongfang Bai wasn’t unfamiliar with moves containing lightning; she had seen sword techniques imbued with lightning before, and their power was truly astounding. She never expected to see one again today, the famous Palm Lightning that only existed in legends.

　　Sandbags are tools used for testing moves in the training ground. Compared to breaking a big tree or a rockery all the time, this method is much less costly and more effective for testing.

　　After all, these have been verified through practice and science. So, in the underground training room in Zhang Weihai’s courtyard, there is no shortage of wooden dummy and sandbags, as well as stone mills and large iron balls for practicing Tai Chi and push hands, and roly-poly toys. It can be described as the legendary scientific cultivation of immortality and scientific martial arts training.

　　Dongfang Bai also really liked this training room, so she, who was already a bit of a martial arts fanatic, would come here to lift weights almost every day when she had nothing to do. Then she witnessed the Palm Thunder.

　　Jiang Yuyan had already tested the strength and defense of the sandbag. With her own power, she could break it, but she couldn’t penetrate it. That would require extremely strong instantaneous penetrating power and explosive force, which was her weakness and shortcoming, as well as the shortcoming of most ordinary martial artists.

　　”What a powerful palm strike! Now I truly believe you can pierce me with a single palm strike.”

　　Xue Qianxun walked directly towards Jiang Yuyan and asked, “Yuyan, I’ve found Cheng Shifei, whom you asked me to find. I’ve been feeding him well for almost three months now. What are your plans? Are you just going to keep feeding him like this?”

　　”Cheng Shifei? What do you want with him?” This was a favor Jiang Yuyan had asked Xue Qianxun, who was on her way back to the capital, to do during the Battle of Songshan. Zhang Weihao was genuinely unaware of this, so he was quite surprised now. He never expected that Jiang Yuyan would be associated with Cheng Shifei.

　　“He’s my sworn brother.” Jiang Yuyan directly revealed the relationship between her family and Cheng Shifei, not feeling there was anything shameful about it. If Zhang Weihao minded or didn’t like it, she could pretend she didn’t know Cheng Shifei; she was truly capable of doing that.

　　They still have a conscience, but not much.

　　”Your mother is Cheng Xin… So it’s your mother… It’s true what they say, ‘I searched high and low but found it right under my nose.'” Originally, Zhang Weihao didn’t plan to contact Gu Santong anymore, mainly because he knew that Gu Santong was practically a madman now. Apart from Cheng Shifei, he would never trust anyone else. His current value was to pass on his skills to Cheng Shifei.

　　”Don’t go see your sworn brother yet. Don’t worry about Qianxun either. Let him fend for himself. He’ll soon have a great opportunity. You can acknowledge him later. I’m going out for a bit. You all stay here and don’t go anywhere. We’ll talk when I get back.” After saying that, Zhang Weihao hurriedly left the training room. Then, he used the Eye of Time and the Transformation Technique to become a generic face and teleported directly to the East Depot.

　　Dongfang Bai, Xue Qianxun, and Jiang Yuyan looked at each other, wondering what had happened.

　　However, Xue Qianxun immediately did as her young master had instructed, returning Cheng Shifei to his original form and leaving him to fend for himself.

　　In fact, Xue Qianxun never met Cheng Shifei. She looked down on such a street urchin. Knowing that Cheng Shifei was a gambler and lazy, she arranged for someone to help him make money in the gambling den, where he could enjoy endless food, drink, and entertainment.

　　Now we’re just letting him vent his anger and return him to his original form. Anyway, this is how he got here, so it shouldn’t make much of a difference.

　　…

　　Upon hearing the telepathic message, Cao Zhengchun immediately went to his study, where he saw a mysterious person and became very alert, wanting to test the waters.

　　Zhang Weihao said directly, “It’s me. Don’t make a sound. Now take me to the bottom of the prison. I plan to see Gu Santong.”

　　”The lord wants to see him? This man has long since gone mad and is completely unyielding.” If he could recruit him, Cao Zhengchun would have done so long ago, but it was no use; the guy himself refused to go out.

　　The reason is simple: he lost a bet and was tricked. He can’t go anywhere that bears the words “Iron-Blooded Marquis”.

　　Zhu Wushi erected an iron plaque engraved with “Iron-Blooded Marquis” at the exit of the Heavenly Prison.

　　Seeing the sign is like seeing the person; what’s blocking him isn’t the sign itself, but the promise. In his view, a man who keeps his promises is a true man.

　　Even though there was a tunnel in the prison, he thought it was a dog hole and would rather be imprisoned for twenty years than crawl through it.

　　Gu Santong has been imprisoned on the ninth floor of the Heavenly Prison for 20 years, and can only use his internal energy to suck up spiders, rats, and geckos from the underground passage to eat every day.

　　Because of a recurrence of an old injury from 20 years ago, he knew he wouldn’t live more than three days. So he passed on all his martial arts skills to Cheng Shifei, whom he felt a great affinity for (which can be seen as a blood connection), hoping that Cheng would help him take revenge and tell Su Xin that he loved her.

　　His end was regrettable; he died without ever knowing that Cheng Shifei was his son, but he kept his promise throughout his life.

　　Zhang Weihao didn’t think he could move such a stubborn and eccentric old man, so he never thought of going to find Gu Santong. But now… this is the father of his concubine Jiang Yuyan’s sworn brother, who is also the father of his cheap brother-in-law. Blood is thicker than water, how can he not lend a hand?

　　“It’s alright, I can bring him out, and he will come out with me, but not now. After I talk to him, I’ll treat him to good food and drink. Don’t worry about those elixirs, rare herbs and treasures, I have plenty here, and you’ll get your share too. Also, give me the Heavenly Fragrance Cardamom you have.”

　　Cao Zhengchun agreed without even thinking. When it comes to dogs, he, Cao Zhengchun, is a professional.
