Language can deceive people, but true Qi cannot.

Therefore, when Su Rui revealed the Supreme Demonic Energy and the White Bone Demon God, Senior Brother Li believed 80% of what he said about him being the Holy Son of the Eastern Demon Cult.

Su Rui saw Brother Li's expression, and a sly look flashed across his eyes. He knew that his performance had impressed Brother Li, and he was secretly delighted. He had to continue to maintain this mysterious aura to make Brother Li believe in his identity.

In Brother Li's mind, Su Rui's image became even more mysterious and majestic. Perhaps Su Rui truly was the Holy Son of the Eastern Demon Cult. If so, he would have to treat him with even greater caution.

Su Rui saw what Senior Brother Li was thinking and decided to press on, making Senior Brother Li completely believe in his identity. He took a deep breath and slowly opened his palm.

"Look again, what is this?"

A fiery demonic banner appeared in Su Rui's palm. As soon as it appeared, it emanated an immense pressure, like a sleeping beast, ready to devour its prey at any moment. Atop the demonic banner, blazing flames shone like dancing fire snakes, and the scorching heat was overwhelming, suffocating.

"This... is this the Demonic Fire Golden Pagoda?" Senior Brother Li asked stutteringly.

"Yes, it's the Devil Fire Golden Pagoda!" Su Rui nodded, deliberately lowering his voice to make it sound more mysterious. Su Rui didn't have a Devil Fire Golden Pagoda. It was just an illusion he created using the energy of the Primordial Mirage. It was just a facade without any real power.

However, these things alone had completely frightened Senior Brother Li! After all, both the Supreme Demonic Qi and the Demonic Fire Golden Pagoda were symbols of the Eastern Demon Cult. If one added the Five Ghosts Locking Heart Hammer, it would be the standard equipment of the Eastern Demon Cult leader.

Senior Brother Li's expression turned strange. He had already made up his mind. What Su Rui had shown had convinced him that he was the Holy Son of the Eastern Demon Cult. Furthermore, he could sense an invisible pressure from Su Rui's words and actions, which made him dare not neglect him in the slightest.

"So...it really is the Holy Son!" Senior Brother Li murmured.

Like the Southern Demon Cult, the Eastern Demon Cult was renowned throughout the cultivation world for its formidable reputation. The Eastern Demon Cult's leader was nicknamed the Five Ghost Heavenly King, and the skulls adorning his Five Ghost Heart-Locking Hammer were forged by renowned masters, a sight that would strike fear into the hearts of all.

Su Rui was secretly delighted, knowing that his plan had succeeded. Now that Senior Brother Li had no doubts about his identity, he could use this opportunity to get closer to Senior Brother Li and gain more benefits and intelligence.

"Brother Li, my identity cannot be revealed to anyone else. Master sent me here to lurk in secret because he received confirmed information that there are spies from the righteous among us, and asked me to conduct a secret investigation. I am taking the risk of revealing my identity to you, but it is out of trust in you," Su Rui said. His voice was low and mysterious, as if it contained endless secrets.

Senior Brother Li nodded dully. After being fooled by Su Rui, he probably didn't have enough brain capacity to think about whether Su Rui's words made sense.

"Brother, the elder wants to see me for something, so why don't we go see him first?"

Before Senior Brother Li's head was about to explode, Su Rui changed the subject and returned to the point.

"Oh... okay, okay!"

He had long forgotten the instructions of the Zhushan Sect elders. When Su Rui mentioned this matter, he remembered it and immediately nodded in agreement.

When the two arrived at the building where the elder of the Bamboo Mountain Sect lived, they discovered that he was using mechanical techniques to refine mechanical men.

"Elder, I invited Junior Brother Ma over!"

Senior Brother Li bowed and shouted to the busy elder of Zhushan Sect.

Okay, here's the added rhetoric:

The Zhushan Sect elder immediately stopped what he was doing, turned around, and looked at Su Rui with piercing eyes. His voice was low and firm, as if it came from far away: "I plan to refine thirty-six mechanical men to explore the Emei Sect's bottom line. Can you arrange for someone to provide some iron ore and materials?"

Su Rui was taken aback when he heard this, thinking he had something important to tell him. However, to forge thirty-six mechanical men, a considerable amount of iron ore and other materials would be needed. It just so happened that the manor actually had quite a bit of ore stored there. It had originally been used by the manor owner to smelt iron and copper, but after the manor was occupied, the ore had been abandoned in a corner. Of course, this was all information dug out from Ma Huai's memories.

"I can provide the iron ore, but you have to teach me the introductory techniques of refining mechanical men, and you also have to let me participate in the entire process of refining your thirty-six mechanical men!" Su Rui pondered for a moment, remembering the heavily armored mechanical man in the copper ring space and the broken mechanical man that Zhang Beiyang placed in the Qingcheng Sect's Lingguan Hall, and then he put forward the conditions.

Upon hearing this, the Zhushan Sect elder frowned and shook his head, firmly saying, "Mechanical engineering is the secret of our Zhushan Sect. There is absolutely no way I can teach it to you!"

His voice was decisive, like a sharp knife, instantly cutting Su Rui's hope.

When Su Rui heard this, his expression suddenly turned cold, and the atmosphere around him began to become chilly.

Upon seeing this, the Zhushan Sect disciple immediately ran to the Zhushan Sect elder and whispered something in his ear. Afterwards, the two communicated using secret techniques. Finally, the elder looked at Su Rui with a hint of suspicion and asked, "Sir, are you really the Holy Son of the Eastern Demon Sect?"

"Could it be possible that my Supreme Demonic Energy is fake?" Su Rui once again encouraged the Supreme Demonic Energy to manifest.

Looking at the black and red evil energy lingering around Su Rui, the elder of Zhushan Sect really took away a bit of it and carefully took it to verify its authenticity.

After just a few breaths, he seemed to have reached a positive conclusion and said to Su Rui, "Your Excellency's status is special. I can take the initiative to teach you the introductory techniques of mechanical engineering. However, you must agree to a request from the Zhushan Sect in the future. How do you do that?"

"Fair enough!" Su Rui nodded. He thought, let the Zhushan Sect find Ma Huai, the Eastern Demon Sect's Holy Son. After all, the real Ma Huai was dead, so there was no way they could trace the cause back to Su Qinghe of the Qingcheng Sect. As long as the Zhushan Sect was willing to teach the art of mechanical engineering, Su Rui would even dare to meet even the most outrageous demands on behalf of the Zhushan Sect's Holy Son!

"However, you have to tell me first, what request do you want me to agree to?" He asked specifically in order to make the elders of Zhushan Sect more convinced.

The Zhushan Sect elder smiled slightly and said, "Why are you so anxious? It won't be too late to talk about it after you have learned the introductory techniques of mechanical engineering."

"Okay, but you must teach me the complete introductory techniques of mechanical engineering right now."

"Don't worry, I've already promised, and I won't break my promise. I always keep my word."

"Okay, then it's a deal. Elder, please start teaching me the introductory techniques of mechanical engineering now."

The Zhushan Sect elder nodded, took out a sheepskin scroll from his bosom, wrote a spell for a while, and then handed it to Su Rui and said, "This is the introductory spell of our Zhushan Sect's mechanical arts!"
