257: secret message

The Blood-Transforming Divine Sabre originally belonged to the Yin Shang General of Seven Heads, Yu Hua, and was a masterpiece among the many Magic Treasures crafted by his Master, Yu Yuan.

Back then, Yu Hua had used this blade to injure several Yin Shang generals in succession, including Nezha and Lei Zhenzi. If not for Yang Jian's versatile transformations, who relied on the Eight Nine Arcane Art to test the poison himself and eventually tricked the antidote out of Yu Yuan, there likely wouldn't have been any subsequent story.

Nezha had once been wounded by this blade, so he was very familiar with its appearance; even now, seeing it still made him feel a lingering fear.

"Heh, that's right, it is the Blood-Transforming Divine Sabre!" Tang Ku said with a smile. "Back then, although this blade was poisonous, its effect was very singular. I don't know what miraculous change it underwent to become the Blood Sea Source, gaining the ability to condense blood Qi. It can be said that the reason Ding Yin was able to become the Undying Blood Demon was largely due to the help of this blade!"

"That's right, the toxicity of this thing was extremely strong back then; even my Lotus Incarnation ability could not escape it... Uh, wait, Holy Monk, you know of this blade? Have you seen it before?"

Nezha asked curiously.

"When I entered the depths of the Blood Cave and saw this blade, my mind was affected by it. It has now developed sentience and took the initiative to transmit some impressions from the War of Investiture into my mind. Of course, there were also subsequent fragments, like remnants of memories, which should be its experiences after Yu Hua was killed. It's just that those images were too fragmented to piece together any complete events!"

Tang Ku laughed. "Alright, the matter is considered closed. Let's go find Xuanji Zi first, discuss the future of Shu Mountain, and then we can return to the capital!"

"Uh... Holy Monk, actually we can't return to the capital yet..."

Xingyunzi suddenly said with a wry smile, "The reason we came here so urgently to find you is actually because there is another matter to tell you..."

Tang Ku was stunned, then he saw Wei Zheng also frowning. Nezha sighed and turned to Tang Ku. "The Emperor of Great Tang has given you another task... Hmm, young man, take out that pigeon message and show it to the Holy Monk..."

Xingyunzi nodded and took a small cylinder from his bosom, handing it to Tang Ku.

Tang Ku pursed his lips and took it, saying, "I thought you were worried about me. It turns out you just wanted me to keep working... Hmm, what is this matter that is so mysterious?"

"Of course we were worried about you, but thinking that with your magic power and shrewdness, dealing with such a simple monster should be effortless, so we didn't worry too much..."

Wei Zheng stroked his beard and smiled... but he noticed that Tang Ku's expression had become serious.

"Who else has seen this letter?" Tang Ku asked Xingyunzi.

"No one else. Only we few know about this matter; no one else knows!" Xingyunzi said.

Tang Ku nodded, then squeezed his right hand tightly. The note in his hand instantly turned into ashes and fell toward the ground.

"This matter is highly confidential and cannot be spread to outsiders. After the business here is concluded, I will write a letter. Xingyunzi, you should have a way to quickly send what I write to the capital, right!"

Xingyunzi asked curiously, "You have the communicator made by my Master in your hand; you should be able to contact the capital directly!"

"No, we don't know if this new thing is being monitored by someone with ulterior motives..."

Tang Ku said in a deep voice, "I need you to write a letter. I will arrange everything step by step on it. If I describe it directly with words, many things will not be clear, and it will be more time-consuming... Hmm, but this is all based on you having a way to quickly transmit the message without letting outsiders know..."

"Heh, that's easy to handle..."

As he spoke, Xingyunzi took out a small cloth bag from the treasure pouch at his waist. After opening the cloth bag, a complete set of the four treasures of the study instantly appeared on the ground.

"Please feel free to use this paper to write. Just sign the name of the person you want to see this letter at the end. Within a day, the person you want to tell in Chang'an City will know!" Xingyunzi laughed.

Tang Ku nodded, knowing there must be something miraculous about it, so he didn't say much. He ground the ink, picked up the brush, and began to write on the rice paper provided by him.

A few minutes later, Tang Ku handed the letter to Xingyunzi. The young man took the letter, folded it over and over in his hands, and before long, a lifelike paper eagle appeared in his palm.

Xingyunzi suddenly blew a breath at the paper eagle. The paper eagle suddenly flapped its wings and flew up. Then, it transformed in the air into a real hawk, nodded at Xingyunzi, and instantly soared into the sky, flying upwards.

Nezha couldn't help but marvel, "This is a good treasure for transmitting information. If there is a war in the future, it can be used to transmit intelligence!"

"This is a temporary experimental product. If we are talking about transmitting intelligence, my Master has better ones... Hmm, Holy Monk, what shall we do next?" Xingyunzi said.

Tang Ku said, "Let's go back to Shu Mountain first and tell Xuanji Zi the news that the Blood Demon has been eliminated. After all, this matter is closely related to Shu Mountain... Moreover, the purpose of our trip hasn't been achieved yet..."

As he spoke, the Blood-Transforming Divine Sabre in his hand flashed a faint white light and disappeared in the blink of an eye.

"The Magic Treasure is spiritual; it seems this fierce weapon has already acknowledged you as its Master!" Nezha said with an envious look.

"Alright, don't you have enough Magic Treasures? The monk only has this one, so don't be envious..." Tang Ku pursed his lips.

After discussing, the group rode the Brick and flew towards Shu Mountain. Soon, everyone had returned to the main peak of Shu Mountain. It was a mess here, but most of the Shu Mountain Disciples had completely recovered to normal and were calling out to clean up the aftermath. Over there, Xuanji Zi was taking two Disciples to treat the seriously injured Disciples.

The protective formation of Shu Mountain was still running, but for Tang Ku and the others, it was effectively non-existent.

When Xuanji Zi saw them appear, he was taken aback, and then immediately bowed to them from afar.

"The Holy Monk is indeed safe and sound. From the moment the Shu Mountain Disciples regained their senses just now, I knew this battle had a result..."

Seeing Tang Ku and the others approach, Xuanji Zi excitedly said to Tang Ku, "Holy Monk... has the Blood Demon already..."

"The Blood Demon has been executed. From now on, there will never be such a monster to harass Shu Mountain or disturb the peace of the world again!" Tang Ku laughed.

"Thank you..." A thousand words could not express his current mood, and in the end, it only turned into this one sentence.

"Heh, you don't have to thank us... In fact, we were entrusted by the current Emperor to earnestly request the Shu Mountain Disciples to come out of the mountains to help. The specific matters are all written in..."

Before Tang Ku could finish his sentence, Wei Zheng, who was beside him, had already handed over a letter.

Handing this letter to Xuanji Zi, Tang Ku said in a deep voice, "This matter is of great importance. If you make a decision, send someone to the Du Xin Domain in Chang'an City three months from now, on the eighth day of the fourth lunar month, and just report my name, Tang Sanzang. Remember not to miss the time..."

Xuanji Zi took the envelope and said solemnly, "Whatever the Holy Monk commands, I will go through fire and water without hesitation..."

Tang Ku couldn't help but smile wryly, "You should read the content before making a decision. This matter is of great importance, and I'm afraid you won't be able to make the call..."
