Qin Renhuang just became an immortal, and you told me this is the prehistoric time

Not long after, Ji Feng, Zhui Ying, Ling Xin, Miao Han and You Zhi arrived at the palace in Xianyang City to report to Ying Xuan.

Ying Xuan immediately summoned Xin Sheng, introduced these demon masters to him, and instructed: "Xin Sheng, these demon masters are good at tracking breath and detoxifying and refining pills. They will definitely help your investigation. You must work together to solve the case as soon as possible."

Xin Sheng clasped his fists and saluted, his eyes firm as he said, "Your Majesty, rest assured. With these helpers, I will be able to find out the mastermind as soon as possible and give justice to our Xian Qin generals!"

Afterwards, Xin Sheng took Ji Feng, Zhui Ying and other demon masters into the military camp again and conducted a more detailed investigation.

…………

In the palace of Xianyang City, after Xin Sheng received the order from Ying Xuan, he did not dare to slack off in the slightest. He quickly arranged everything and waited for the arrival of the demon master.

As soon as they entered the military camp, Xiaotian and Zhufeng devoted their full attention to the tracking work.

Their nostrils slightly opened, carefully sniffing every breath in the air, not missing any clues.

Zhufeng walked slowly along the edge of the tent. Suddenly, it paused and growled in a low voice, "There is a strange smell here. Although it is faint, it is unusual."

Xiaotian came quickly, and after carefully distinguishing the same place, he nodded in agreement: "Yes, this is definitely not the smell that should be in the military camp. It must be left by outsiders. This smell is a bit like the smell left by Buddhism."

Upon hearing this, Xin Sheng looked solemn and immediately ordered his soldiers to block the surrounding area. He then said to Xiaotian and Zhufeng, "Follow this scent and make sure to find the source."

"Yes, sir!" The two dog demons responded and followed the faint scent.

Sometimes they run as fast as the wind, sometimes they lie on the ground and sniff, moving forward in the complex environment of the military camp.

Lingxuan, Yalan and Jingmei went straight to the generals' tents and began to conduct a detailed inspection of the generals' food and daily necessities one by one.

Lingxuan picked up a wine jug, shook it gently, then closed her eyes and used her spiritual power to sense the subtle components in it.

After a long while, she opened her eyes and said solemnly, "There is an extremely secret poison smell left in this wine pot. The poison is made with exquisite techniques. It can erode a person's cultivation without them knowing, and it is extremely difficult to detect."

Yalan and Jingmei were also busy. Yalan found that the wine in the wine pot on the bedding was mixed with poison. She carefully collected it and said after examining it carefully: "These are the poisons. General, I will accept the wine. We will start researching and see if we can refine an antidote for this drug."

Lingxuan listened, Jingmei took the wine, sniffed it, and twisted it with her fingers. With her superb knowledge of alchemy, she analyzed: "This wine contains a rare poisonous grass ingredient. Only after mixing with several other substances can it play the role of corroding cultivation. It seems that the person behind this has great attainments in poison refining."

At this time, the general in the military camp looked at the monsters in front of him and was delighted when he found out the poison he had been poisoned with.

"My fellow immortals, are you sure you can create an interpretation sheet to restore my cultivation?" the general asked anxiously.

Yalan and the other monsters looked at each other, had a detailed discussion, and quickly gave an answer.

"General, please be patient. We have just investigated the ingredients of the medicine and want to refine the corresponding detoxification pill. It may take some time and we cannot guarantee that it can reduce your poison 100%. However, we humans and demons are allies now, and we will definitely do our best to help you." Ya Lan said solemnly.

This also gave the general and several other human soldiers who came in later a sense of hope.

Meanwhile on the other side.

While everyone was investigating intensively, Xiaotian and Zhufeng tracked the mysterious aura all the way to a dense forest outside the military camp.

However, by the side of a stream, the breath suddenly disappeared without a trace.

Xiaotian paced back and forth around the stream, letting out a low roar: "Strange, why did the breath stop here? The other party obviously did it on purpose to cover up his whereabouts." Zhufeng also looked puzzled, but it did not give up and carefully searched around for any possible clues.

Suddenly, it found some tiny scratches on a tree by the stream, as if it had been scratched by some sharp object.

"Xiaotian, look here." Zhufeng pointed at the scratches and said, "These scratches are very new. They should have been left not long ago. Maybe they are related to that mysterious person."

Xiaotian came over and said after careful observation: "Yes, this may be the trace he accidentally left when he left. Let's continue looking in this direction."

The two dog demons continued to search deeper into the dense forest in the direction indicated by the scratches.

Meanwhile, in the military camp, Lingxuan and others were also working hard to crack the composition of the poison and try to find an antidote.

After some arduous investigation, Xiaotian and Zhufeng finally found a hidden cave deep in the dense forest.

There was a faint mist around the cave entrance, exuding a mysterious atmosphere.

"Maybe the person we are looking for is hiding here." Xiaotian said in a low voice, his eyes revealing vigilance and excitement.

Zhufeng nodded slightly and approached the cave entrance cautiously, ready to find out what was going on.

At this time, a human army also rushed over from the rear. These soldiers were the subordinates assigned to them by Xingsheng and could be deployed by them at will.

"team leader!"

The leading sergeant came over and reported.

Xiaotian nodded and signaled them to follow him into the cave to capture the criminal.

…………

The setting sun was as red as blood, and the afterglow fell on the wasteland in front of the cave, creating a strange, bloody red color, as if it was blood oozing out of a torn wound in the earth.

The entrance of the cave is surrounded by rugged rocks and entangled with dead vines, and is filled with a foul smell. The dead silence makes people shudder, and the only sound is the whistling of the wind in the ears.

"This is it. Everyone, be alert and be careful of traps." Xiaotian said in a low voice, while tightening the long sword in his hand that was flashing with cold light.

He took a deep breath and moved carefully into the cave step by step, taking each step extremely cautiously for fear of triggering some fatal mechanism.

After all, they had been searching for so long before they found the intermediary behind the scenes, and this person was able to make so many high-ranking personnel in the Xian Qin army be infected without anyone noticing, and it was not until a long time later that they discovered that this person was very vicious and meticulous.

It is absolutely impossible to achieve this without extremely powerful cultivation.

So they were all very careful.

As they continued to dive deeper, the cave became dark and damp, with the walls covered with slippery moss. Water droplets fell from the top of the cave, and the dripping sound was infinitely amplified in the dead silence, as if every drop of water hit everyone's tense heartstrings, making their hearts beat involuntarily to the rhythm.

At this moment, deep in the cave, a bottle emitting a faint glow stood quietly on a huge rock. (End of this chapter)
