Li Xian suddenly thought that the night he was in Banpo Town, if the old man hadn't stopped him in time, he was afraid that his ending would be the same as the two young men and half-ghosts just now.

"Uncle, you have been following me before, just to prevent me from inadvertently breaking the covenant and being refined." Li Xian said gratefully.

"This is a secondary reason. The main thing is that I want to know your character thoroughly, after all, I have something important to entrust to you. The old man did not hide it, "You are bold and careful, calm in trouble, and kind in nature." I'm very satisfied......"

While speaking, the old man had already taken Li Xian and flew to the sky above Qianshan City.

Seeing that the old man kept looking around, Li Xian understood that he must be looking for the next case.

The old man wants to let himself pass these real cases and firmly remember the "Half-Ghost Convention".

"Uncle, in fact, you just need to tell me about it once-" Li Xian has always been reluctant to trouble others.

"There are only three half-ghost conventions, and every half-ghost knows about them, but there are still many half-ghosts who die every day because of violating the convention!" The old man said solemnly, "Half-ghosts don't have too many constraints like humans, but once they are violated, there is only one way to die. I have to make it unforgettable for you. ”

"Thank you." Li Xian no longer shirked.

After flying for a while, the old man suddenly sighed and said, "It's time for another piece of high-profile news on the Internet!" ”

"What did you find?" Li Xian asked as he looked down.

The following is the Qianshan City Jingyi Road Viaduct Project under construction.

Qianshan City has developed rapidly in recent years, with more and more private cars, and the road is becoming more and more congested, almost side by side with the "first block".

In order to solve the traffic problem, the municipality has been vigorously building viaducts in recent years.

Jingyi Road is the main road, and the road is only half closed, half of the bridge is repaired, and half is passable.

"Not good!" Without waiting for the old man to answer, Li Xian also found a problem, a broken bridge was sliding towards the other half of the road crowded with pedestrians and buses.

Pedestrians also noticed this terrifying scene, although the speed of the bridge sliding was not fast, but because the road was too crowded, everyone had no way to escape for a while, and they all screamed in fear and made a mess.

At this moment, a strong man half-ghost flew over, and with a strong push with both hands, the bridge that was slipping down stopped. The crowd couldn't see the strong man and the half-ghost, thinking that the bridge had just stopped out of thin air.

The crowd took advantage of this opportunity to flee into the distance.

"This must be blessed by the gods!" The elderly onlookers chanted Amitabha.

"Wow, this is fine, these people's lives are really big!" Some cynical young people took out their mobile phones, took videos of videos, and sent WeChat messages.

Li Xian also breathed a sigh of relief and praised: "What a good person, oh, what a ghost!" He's so strong! ”

The expression on the old man's face did not relax in the slightest, but became a little more sad, and he shook his head and said: "He, like me, is from a ground-level rune, and he can store ten taels of yang qi in the sea of qi......"

All the actions of the half-ghost are related to yang energy.

In order to prevent the humans around them from discovering their identity, some half-ghosts will often eat and drink with them. These meals, which are of no use to the half-ghosts, have to be digested by yang energy.

Half-ghosts can also be exposed to the sun like humans, but at this time, they also consume much more yang energy.

Two half-ghosts fight, and the yang-footed one always wins.

……

The old man took the opportunity to introduce these common senses to Li Xian.

Li Xian suddenly found that the strong man was about to lose his support.

"The yang qi in his sea of qi was originally less than ten taels, and he was almost exhausted." The old man said.

"I'm going to help him!" Li Xian jumped hard, and he was about to rush over.

But the old man grabbed him.

"Uncle, we can't just watch—" Before Li Xian's words were finished, he suddenly saw the expressionless ghost in black clothes again. They opened the cloth bag and put the strong man in it.

The half-section of the bridge, which was blocked by the strong man, instantly slipped down and smashed into the front of a bus that had not had time to escape.

Screams, cries, moans, came from the bus.

"Bastard!" Li Xian angrily scolded at the black-clothed ghost, "You still have no humanity!" ”

The ghost in black didn't look at him, and left silently.

"This is Article 2 of the Half-Ghost Convention, which does not allow too much interference in human society, even if it is to do good deeds." The old man said, "This is the easiest thing to offend in the early stage of human transformation into half-ghosts. ”

The old man thought for a moment, and then said, "For example, if there is a war between our country and the enemy country at this time, will you join the war?" ”

Without waiting for Li Xian to answer, the old man continued: "You must know that if the yang energy is enough, a prefecture-level half-ghost can destroy a city. That is, if there are half-ghosts participating, our country's army will be invincible. ”

Li Xian was moved when he heard this: "Strange, during the Anti-Japanese War, why didn't the half-ghosts come out and eliminate those invading devils in one fell swoop?" ”

"If we go to war, will the half-ghosts of the enemy country not go to war? Originally, it was just a war between humans, but in the end, it evolved into a war between half-ghosts. No matter how great the destructive power of human warfare is, it is limited, but because of the participation of half-ghosts, the number of people who cause damage and deaths will increase hundreds of times! So, do you think you're helping humanity or harming humanity? ”

Li Xian was speechless.

The old man continued: "Just now, the bridge was quietly removed by the man, and no one was hurt. Do you think anyone will pay attention to this? ”

"Uncle, I understand. Today, this accident will soon spread all over the Internet, and the relevant departments will pay attention to it, and the relevant responsible persons will be severely punished, so that more construction units can take warning......"

"So blessings and misfortunes have always depended on each other, and it is difficult to distinguish between good and evil!" Seeing Li Xian's solemn expression, the old man said with a smile, "So the 'Half-Ghost Convention' set by the underworld still makes sense." ”

"Was the Half-Ghost Convention made by the underworld? So those law enforcement officers are the real ghosts? ”

"No, they are all half-ghosts, but they are all under the direct leadership of the underworld, which is equivalent to civil servants in human society." The old man introduced, "Ghosts live in the underworld, and people and half-ghosts live in the earth. People and half-ghosts can't go to the underworld, and ghosts are forbidden to come to the yang world. ”

"It turns out that all the ghosts around me are only half-ghosts." Li Xian was stunned.

"Exactly. It's just that everyone is accustomed to calling half-ghosts ghosts, and after a long time, those low-level half-ghosts who don't know anything also think they are real ghosts. The old man laughed.
