"Look at your own papers, don't look left and right, don't look at other people's answers, otherwise you know the consequences. Ren Baqian sat at the front of the classroom with his eyes like an eagle falcon patrolling everyone, and the Bayi rifle was placed on his knees, and the threat was self-evident.

The people below looked at the test paper that had just been distributed, and finally knew what the exam meant, and they all looked sad, and many people were looking left and right.

When Ren Baqian's words came down, everyone immediately looked down at their scrolls honestly.

After a few moments, everyone picked up their pens and began to answer.

These days, everyone has also adapted to a kind of big bird's hair pen made by Ren Baqian, and began to write after getting used to some ink, which is much faster than the brush after getting used to it.

"Bang!"

The sudden gunfire startled everyone.

"Du Lao Liu, warn once, next time you look to the side, you will recuperate at home. Ren Baqian said lightly.

Du Lao Liu was startled, muttered in his heart, and honestly looked at his papers.

Others didn't dare to make any small moves.

After all, the deterrent of firearms to them is still relatively large.

I can't die, but it hurts!

An hour passed, and the alarm clock that Ren Baqian put next to him suddenly rang, startling everyone again.

The alarm clock was also the first time they had seen it.

"When the time comes, the papers will be handed to me. Ren Baqian patted the lectern next to him and said to everyone.

After everyone had handed in the papers, he took them and left.

When he left, everyone began to ask each other, "How fast does the sound travel?"

"What is the melting point of iron?"

"Do convex or concave lenses diverge light?"

......

Ren Baqian first sent the exam papers back to Pingle Garden, and on the way he came, a lot of thick wooden pillars had been erected on both sides, about six meters high, each pillar was about the same thickness, and the bark on the outside was knocked off and coated with a layer of plant juice, which could play a certain role in embalming.

In addition, the wood itself is not easy to be eaten by insects, and it should be able to be used for several years.

These pillars have just been installed, the street lights have not been pressed, and the batteries and street lights brought with them are not enough to install them.

Ren Baqian came to the front of the Heart Cultivation Hall and saw several boxes on the ground, and several craftsmen were already waiting beside them.

First of all, I told these craftsmen how to connect the solar panels with the batteries and light bulbs, although they didn't know what it did, but they did a good job under the command of Ren Baqian.

They first jumped to a height of more than two meters by themselves, then climbed to the top like apes, clamped their legs between the wooden posts, and then used ropes to lift the solar panels, battery bulbs, and lampshades in the basket, and then began to install.

After they finished loading, Ren Baqian climbed up and took a look, and the load turned out to be good.

It was a little slow at first, but after installing a few, I became more and more proficient. Ren Baqian felt that the learning ability of these craftsmen was much better than that of the fools in the academy.

Twenty sets of street lamps were installed in one afternoon, six of which were in front of the Heart Cultivation Palace, and the rest were on the way from the Heart Cultivation Hall to Pingle Garden.

Ren Baqian hopes that this paragraph will at least light up first.

After doing this, Ren Baqian went into the Heart Cultivation Hall to accompany the empress, waiting for the evening to come.

"How many days are you going to the mountains?" asked the empress.

"Yes, salt is a big deal, and it will be resolved this morning. If you can't solve it, think of other ways as soon as possible. Ren Baqian replied.

He wasn't sure if he could produce well salt, but he had to give it a try.

"Oh!" the Empress nodded and said nothing.

"But from tonight onwards, the outside of the Heart Nourishing Hall will always be bright, and Your Majesty will go outside to look at the stars, so there will be no need to carry a lantern. Ren Baqian said with a smile.

Speaking of street lamps, the empress is much happier.

Although there are still various gaps with the earth, it is always necessary to take it step by step.

Looking at the little changes in the palace, and the things that those students were learning from Professor Ren Yachi, she felt that she would be able to see Da Yao as prosperous and beautiful as the earth in her lifetime.

"Today, Great Xia sent troops. The empress said inadvertently.

"So fast?" Ren Baqian was a little surprised. It has only been a week since the last time the Great Xia Emperor questioned it.

Da Xia, I really can't wait.

"Now that they have decided to fight and are ready, they will naturally not delay any longer. "The empress is not surprised.

"In the afternoon, Tiesuo Pass sent out an army of 150,000 troops in front of Pingcheng, and there were three rounds of trebuchets and other ordnance stones. However, General Hongwu said that their targets may be in Shuncheng and Ziyue City, and they have already asked them to strengthen their vigilance and be careful of night attacks.

We'll find out tomorrow. The empress said lightly.

Ren Baqian has seen the map of Da Yao He Da Xia these days, and the cities and checkpoints adjacent to Da Xia and Da Yao are mainly these places, Tiesuo Pass and Pingcheng, Qingyang Pass and Shun City, Yunluo City and Ziyue City.

Of course, the two countries are bordered by large plains and valleys, but these are the main places.

If you don't get rid of these three places, coming from other places will easily be blocked from the back road, and the logistics will be unsustainable.

So if their goal is the whole of Dayao, they must destroy one of the cities to ensure that the route is smooth.

"The Red Warrior should be able to stop them. Ren Baqian said.

He didn't know much about Hongwu, but Hongwu had been stationed at the border for decades, and his reputation was extremely high, and he was not comparable to ordinary people on how to use soldiers.

There are still 30,000 ancient warriors in his hands, as well as drones, binoculars and walkie-talkies provided by himself, presumably there should be no problem in blocking the Great Xia Army in a short time.

The empress also bowed: "This is nature." ”

The tone was all trust in Hongwu.

After the two had dinner, Ren Baqian heard a small noise outside. When I turned my head and saw that it was already dark outside, it was different from the previous darkness, and there was still a certain amount of light, so I knew that the street lights were okay.

"Your Majesty, go out and have a look, the starry sky tonight must be beautiful. Ren Baqian stretched out a hand and invited.

"Good!" replied the empress with a smile on her eyebrows.

Ren Baqian took the opportunity to take the empress's hand and walked out, and both of them could see the light coming from outside at this time.

When I got out of the Heart Cultivation Palace, I saw that the guards outside were all in a daze, barely closing their mouths.

When these pillars were installed before, no one expected that it would have such an effect, and it would automatically glow after it got dark, and it was not at all comparable to the lanterns commonly used in the palace.

At this time, twelve wooden pillars were erected in the courtyard outside the Heart Cultivation Hall, and the tops of six of the wooden pillars were emitting a white light, illuminating all the surrounding scenes.

It's not like daytime, but you can see it quite clearly from inside the yard.

"Cough!" Ren Baqian coughed, and the four guards outside reacted and turned to salute: "I've seen Your Majesty!"

The empress nodded slightly, did not speak, and let Ren Baqian lead her under the street lamp.

Ren Baqian led the empress out of the courtyard of the Heart Cultivation Palace, and there were still two rows of street lamps outside, but only one row was on.

The two of them walked on this road, one black and one red, moving forward slowly.

Ren Baqian is in a good mood, and Da Yao has also appeared with street lights, although they are all brought from the earth now, and sooner or later they will be made by themselves.

"The starry sky is exceptionally bright tonight!" Ren Baqian said with a smile.

The Empress turned her head to look behind her, then at the front, "That's all there is to it. ”

The distance between the two street lights is six zhang, that is, about 20 meters. Fourteen street lamps illuminated the stretch of the road from the Heart Cultivation Hall to the Pingle Garden, and many people in the palace were watching the road that suddenly brightened up from a distance, but it was still dark elsewhere.

"Soon, it will fill the whole palace. And then one day, it will be all over Dayao. Ren Baqian said with a smile.

"I'm waiting to see that day. The Empress had a smile on her face.
