Outside the city of Chang'an, in the mountains.

Di Renjie stepped on the ground with both feet, and he was still a little unsteady, and after a while, Li Yuanfang, who had just changed back from Ultraman Tiga's form, hurriedly reached out to support him.

"It's okay, it's okay."

Di Renjie waved his hand, raised his head, and looked at the surrounding scenery.

"It's just a few breaths, and you can fly in the air and come from Jiangjiao County to the outside of Chang'an City, this is really a fairy method......

"That's exactly why, the humble position also used this immortal form to come directly from Lingzhou City to the tent. It's just that the gang didn't seem to anticipate this, so they waited for three days in the county before waiting for the lord."

"Oh? That'......" Di Renjie was stunned for a moment, and seemed to be thoughtful.

About a quarter of an hour ago, they were still in that small alley in Jiangyi County, and Di Renjie came up with an idea almost instantly after knowing that Li Yuanfang did have the ability to transform into an immortal like Ultraman Tiga.

They hid in place, waiting for the killers who were ambushed outside the city to wait impatiently, and when they came in to investigate, they only saw the corpses of the killers all over the ground, and immediately thought it was Di Renjie and Li Yuanfang They ran away.

And on the side of the post house, because Di Renjie and Li Yuanfang did not go back, they were still in a state of ignorance, and there was no need for the killers to ask for hardships and attack a pavilion without Di Renjie.

After those killers left, Di Renjie asked Li Yuanfang to transform into Ultraman Tiga again, took him with him, and flew directly outside Chang'an City - because this Ultraman form was too conspicuous, it was inconvenient to appear in the city.

Di Renjie was held in his hand by Li Yuanfang, protected by the "immortal technique" that he didn't know how to use, and almost in a few breaths, he crossed hundreds of kilometers and came to the mountain outside Chang'an City, and he didn't even have the time limit for transformation.

"My lord, can those people tell the prophet in advance that you are about to go to Jiangyi County, does it explain your whereabouts......

"You're saying that there might be a maid by my side?"

"Exactly." Li Yuanfang nodded and said with a serious face.

"If it is said that there are women in the court, it is possible, but they don't need to put people around me." Di Renjie explained, "The route I set out from Pengze County to Chang'an was escorted by the imperial court's imperial guards, and their route was also known to people in the imperial court. That's why I asked if you could bring me to Chang'an quickly, and I was going to catch them off guard."

"Yuan Fang, you have not been in the army for a short time, you should understand the principle of "soldier and god speed", now you can send me here as an immortal, this is definitely what those people did not expect, they are not prepared, in a hurry, there will definitely be a lot of horses."

"I see." Li Yuanfang nodded in a sudden realization, but seeing Di Renjie's contemplative appearance, he couldn't help but speak.

"Your Excellency, ...... Aren't you surprised, or afraid, of me getting the power of an immortal?"

Di Renjie glanced at him and asked rhetorically, "Strange must be strange, but since you don't know it yourself, it's useless to ask. As for being afraid, just now when I was flying at a height of ten thousand feet, you only need to gently tilt your hand, and I will fall into a pulp, I was not afraid at that time, but now I am afraid, what are I doing?"

"Ugh...... Because in general, people are afraid of ghosts and spirits......

"Hehe, my Di Huaiying has lived a life, although I dare not say that I am above board and have never done anything wrong, but I can also say that I am worthy of the sky and the people. If there really is an immortal, naturally they won't trouble me; If it's that evil spirit and evil ghost......" He glanced at Li Yuanfang, "Isn't it just right for you, the son of an immortal, to kill?"

When Li Yuanfang heard this, it seemed to be the truth, and he smiled a little embarrassedly.

In fact, he still hasn't turned a corner, he doesn't regard himself as a special existence, in his own subconscious, it is nothing more than his own martial arts progress, he used to be able to walk a hundred miles in a day and a night, but now he can walk a hundred miles in just a few breaths.

"What are we going to do now, my lord?"

Di Renjie said: "At the moment, those killers don't know that you and I have arrived in Chang'an, let's not expose our whereabouts for the time being, we can take the opportunity to investigate and see Chang'an City."

Did anything strange ever happen? After that, I will go to the capital and explain to her."

"Oh, by the way, since your immortal posture has come and gone for hundreds of miles in an instant, we can also go to the Gannan Dao desert once to see if there are any clues. In addition, after explaining to the emperor, we will go to Youzhou again."

"Youzhou?" Li Yuanfang said curiously, "What are you going to do there?"

"Isn't it suspicious that Qianniuwei, who pretended to convey the holy decree, obviously has a Youzhou accent, but he lied that he was from Shandong. In addition, Youzhou borders the Turks to the north, and the murder of the Turkic mission also involved the Turks."

"Then my lord, why don't we just find out the case and explain it to the Holy One?"

Di Renjie looked at this stunned young man and couldn't help laughing: "How can it be so simple, I'm afraid this case will not be difficult to solve in a few months. Now that you are a criminal person, and you have difficulty moving in many ways, do you have to hide everywhere when you investigate the case?"

"Although you have the power of immortals, you come and go like the wind, and your body is as strong as a mountain. However, the investigation of the case is not done by strength alone, it is the so-called "method of handling the case" of the likes of Lai Junchen, so in the matter of investigating the case, a holy decree can be better than the power of your immortals."

Li Yuanfang nodded, the two went down the mountain in parallel, and they just entered the city at dawn, and when they arrived in the city, the two found an inn to live in, and inquired about the news.

The next day, the two appeared in a clay kiln in the east of the city, which was located in the middle of nowhere, and it was said that a fire broke out on the day when the main guard of Yiyang County was killed and the identity of the fake Turkic mission was revealed, but no one connected the matter.

In addition, it is said that the gate of Chang'an City was also under martial law for no reason that day, and people had to be searched when they entered and exited.

The two investigated in the earthen kiln and found a lake silk handkerchief from the ruins, which was exactly the same as the lake silk handkerchief left by Li Yuanfang when he fought against the mysterious man who called himself "Pit Viper".

Therefore, Di Renjie concluded that the fire in this earthen kiln was not accidental, but a planned attack by pit vipers.

In chronological order, it should be that the pit viper attacked the earthen kiln first, and the emperor immediately blocked the city gate when he heard about this, and then the main guard of the next Yang County was attacked, and the killers pretended to be guards to go out of the city.

The purpose of this series of actions is to rescue a person from the earthen kiln, and when the earthen kiln is on fire and the city gate is closed, he will leave with the sedan chair of the chief of Yiyang County, which will never be searched.

After figuring out this joint, Di Renjie heard that Emperor Wu Zetian was going to go to Yuanjue Temple to make incense in three days, so he and Li Yuanfang took advantage of these three days to go to Gannan Province to investigate.
