Please don't force me to be a god.

However, the lightning was attracted by a long iron rod more than ten meters above the ground.

"Boom..."

A thunderous explosion sounded, and the lightning and the long iron rod collided, splashing a ball of sparks.

This long iron rod was an iron spear, originally used to strengthen people's strength.

Zhang Tian borrowed it from General Guo, tied an iron rope to it, erected a pillar more than ten meters high, and buried it in the parade ground.

A simple lightning rod was made.

The lightning passed through the iron rope under the spear and was led into the ground, disappearing without a trace.

Zhang Tian nodded with satisfaction. Although it was a bit crude, the effect was still very obvious.

"Crack... Crack... Crack..."

The lightning rod struck continuously, but all were intercepted by the lightning rod, and none of them struck Zhang Tian.

The strong current continued to pass through the thick iron rope and was led into the ground.

When the dark clouds in the sky finally disappeared, the iron rope had burned red.

Zhang Tian looked up at the sky and breathed a sigh of relief, which meant that it was not done by some gods.

Otherwise, such a simple lightning rod would definitely not be hidden.

Then he would have to run all over the school field to escape for his life.

However, the problem was not completely solved.

Zhang Tian whispered: "Xiao Jiu, will I be struck by lightning every time I go out in the future?"

"Captain, preliminary calculations show that it should be the special nature of your biomagnetic field that has accumulated too much charge. Just like static electricity in winter, as long as it is released in time, it should not cause lightning again."

"Well, I'll try again tomorrow." Zhang Tian nodded.

This is similar to touching metal with both hands to release static electricity before repairing precision instruments.

Everyone around was stunned.

The lightning that struck Zhang Tian yesterday was actually resolved by a simple device.

Zhang Tian was seen talking to himself again, as if he was talking to someone.

He was so scared that he dared not breathe.

Seeing that Zhang Tian seemed to have finished talking, Xu Wen bravely said, "My Lord, what is this pillar? It can actually dispel the punishment from heaven?"

"This is called a lightning rod. As the name suggests, if there are frequent thunderstorms in a certain place, you can avoid being struck by lightning by installing such a thing."

Xu Wen's eyes widened immediately: "Hide the truth from the heavens? It turns out that there is really a way to deceive the heavens. My Lord, can we mortals use such a way to deceive the heavens?"

"Yes!"

"Then do you want to kill chickens and sheep..."

"Huh?!" Zhang Tian stared at Xu Wen, his eyes full of warnings.

This guy is here again. If you say one more word, he will throw you out.

Xu Wen quickly covered his mouth and sat down obediently.

The person next to him whispered, "Brother Xu, this matter involves the taboos of heaven, so don't ask."

"Just now the immortal muttered to himself, probably he had informed the higher-ups."

"Yes, we just need to listen to the immortal."

"With this method of deceiving heaven, the house will not be afraid of being struck by lightning in the future."

Xu Wen was still a little uneasy: "Before installing this lightning rod, would it be better if we slaughtered chickens and sheep for worship?"

"Go away!!"

…………

After a lot of trouble, the content of blood transfusion was finally finished.

It is not difficult to distinguish arteries and veins, and medical skills at this time have already been discussed.

It is not difficult to make needles, or even blood transfusion hoses.

As long as you have a little patience, many craftsmen can make them.

The difficult part is to distinguish blood types.

In later generations, this is the truth that has been exchanged for countless lives.

Modern tools for detecting blood types seem simple, but they involve a lot of physical and physiological knowledge, as well as industrial manufacturing capabilities.

The medical detector in Zhang Tian's hand can detect blood type, but he has to keep it for his own use.

Pointing out the direction for them is the limit of what Zhang Tian can do.

Believe that the wisdom of the general public can greatly shorten the time to invent blood type detection equipment.

The seeds have been planted, let them take root, sprout, bloom and bear fruit naturally.

After the lecture, Zhang Tian drove them out.

These dozens of people stared at him with tears in their eyes the whole time.

When they were a little excited, they would fall to the ground and cry, with tears and snot flowing together, showing everyone what true gratitude is.

Especially Xu Wen, who was full of ghosts and gods, and always flattered his thighs.

Zhang Tian couldn't stand them, so he drove them all away, out of sight, out of mind.

…………

As soon as they left the general's mansion, the students were surrounded by a large number of people again.

Someone shouted, "I originally offered thirty strings of cash to buy a copy of your notebook."

"Xu Xiucai, I'll offer fifty strings of cash for your notebook. I'd also like to invite you to come to my Zhang family in the north of the city to teach me the magic, and the price will be calculated separately."

At this time, someone jumped out and said, "I'll offer a hundred strings of cash, Xu Xiucai, please come to my Qian family to teach first. Zhang Baiwan, you took advantage of me on Xianrenzui, and this time I mustLearned before your family did. ”

The speaker was Qian Manduo, who was called "Qian Lao Si".

Before in the military camp, he wanted to buy wine but failed, but Zhang Baiwan persuaded the general to drink a sip.

When they reached their status, they were fighting for their dignity, and the price was secondary.

Zhang Baiwan said: "Humph, Qian Lao Si, it depends on whether you have the financial resources. I will give you 150 strings of cash."

"Two hundred strings of cash..."

"Wait!" Xu Wen interrupted, "A gentleman loves money and gets it in a proper way."

"The immortal said that the art of resurrection and the art of borrowing life are not secret, and anyone can teach them, but he did not say whether he can accept money."

"Even if you dare to give it, I dare not accept it. I have to ask the immortal about this matter."

The other students nodded and said: "That's right. I'm ashamed that we almost got into the money."

"The immortal taught this method to benefit the people. If we turn around and use it to make a profit, I'm afraid the immortal will be unhappy and may punish us from heaven..."

Speaking of heavenly punishment, everyone shuddered.

Whether it was the hundred-meter-long flames fighting against the Hu army outside the city or the thunder and lightning in the general's mansion, they were beyond their imagination.

If we really violated the will of the immortal, we might have to go to the eighteenth level of hell after death.

Thinking of this, my heart was cold.

Some people who had just sold their notebooks hurriedly returned the money and waited to see what happened.

"Why don't we go back and ask the immortal?"

"That makes sense. Captain Niu, please inform me?"

Niu Er was very active in anything related to Zhang Tian and trotted in.

After a while, only he came out and said loudly: "The original words of the immortal: You can collect money to make a living, but you must not teach. ”

Everyone was relieved, especially the poor scholars among the students.

Studying was a luxury in this era, and many ordinary families could go from being well-off to being extremely poor.

But they were too embarrassed to do rough work because of the face of the scholars.

With the promise of the immortal, they could earn some income in a fair and honest way without losing the face of the scholars.

They were the first batch of students, with the halo of "immortals passing on the law".

Even after these two technologies were widely spread, there were still many people who wanted to learn from them, and they had no worries about their livelihood.

Some people were grateful and suggested: "The immortals repelled the Hu army twice and passed down this immortal law to save the people. Why don't we build an immortal temple and worship it day and night to add some incense to the immortal?"

"Good idea, I will contact the elders and let them preside over it."

"Yes, this matter cannot be sloppy. It must be presided over by the respected elders of the clan. "

The crowd was talking and walking, and they were about to disperse.

"Wait!" Niu Er shouted hurriedly, "This is not right."

Everyone turned around and asked, "Captain Niu, what's wrong? Don't you want to worship the immortal?"

How dare you say that worshiping the immortal is "not right"?

If the person who spoke was not from the general's mansion, I'm afraid someone would have cursed him.

Niu Er said, "The immortal doesn't eat incense."

"I sent incense to the immortal before, and he told me to throw it aside."

"The immortal gave me guidance and cured my hidden disease. I wanted to worship him, and the immortal scolded me: Do you want him to die soon? "

"Later, he said: If you dare to worship him again, he will beat me!"

"If you are not afraid of being beaten by the immortal, just go and worship."

"This..." Everyone whispered to each other, "What should I do? ”

“The Immortal has done great favors to our Xiangyang City and the common people. How can we express our endless respect?”

At this time, Xu Wen said: “Don’t worry. The Immortal is a living god, not a clay statue in the temple. If you have a chance to meet the Immortal in the future, just ask him in person.”

“Well, that makes sense.”

“I heard from Captain Niu that the Immortal eats mortal food. I will send some fruits and meat to see if the Immortal likes it.”

Xu Wen’s eyes lit up: “Yes, I will kill chickens and sheep and send them to honor the Immortal…”
