"Look at your own papers. You are not allowed to look around or look at other people's answers. Otherwise, you know the consequences." Ren Baqian sat at the front of the classroom and scanned everyone with his hawk-like eyes. The Type 81 rifle was placed on his knees, and the threat was obvious.
Everyone looked at the papers that had just been handed out. They finally knew what an exam was. Everyone frowned and looked around.
When Ren Baqian's words were passed down, everyone immediately lowered their heads and looked at their own papers.
After a while, everyone picked up their pens and started to answer.
These days, everyone had gotten used to the brush made from the feathers of a big bird. They dipped the brush in ink and started to write. After getting used to it, it was much faster than using a brush.
"Bang!"
The sudden gunshot startled everyone.
"Du Laoliu, I'm warning you. If you look to the side again, you will have to recuperate at home," Ren Baqian said faintly.
Du Laoliu was shocked. He muttered in his heart and looked at his own papers obediently.
The others didn't dare to do anything.
After all, guns were a big deterrent to them.
Even though they wouldn't die, it was still very painful!
After an hour, the alarm clock that Ren Baqian placed at the side suddenly rang, giving everyone another shock.
This was also the first time they saw an alarm clock.
"Time's up. Hand me all the papers," Ren Baqian patted the desk beside him and said to everyone.
After everyone handed in their papers, he took the papers and left.
After he left, everyone started to ask each other, "What's the speed at which sound travels?"
"What's the melting point of iron?"
"Does a convex or concave lens emit light?"
…
Ren Baqian first sent the papers back to Pingle Park. Along the way, there were already many thick wooden pillars erected on both sides of the road. They were about six meters tall, and every pillar was about the same thickness. After the bark was peeled off, a layer of plant sap was applied to the pillars, which had a certain antiseptic effect.
In addition, the wood itself wasn't easily eaten by insects, so it should be able to be used for a few years.
These pillars had just been installed, and the street lamps hadn't been installed yet. The batteries and street lamps that were brought here weren't enough to install all these.
When Ren Baqian arrived at Yangxin Palace Hall, he saw a few boxes on the ground. A few craftsmen were already waiting at the side.
Ren Baqian first taught these craftsmen how to connect the solar panels to the batteries and light bulbs. Even though they didn't know what they were used for, they did a good job under Ren Baqian's instructions.
First, one of them leaped to a height of more than two meters. Then, they climbed to the top like apes, clamped their legs on the wooden pillar, and used a rope to hang the solar panel, battery bulb, and lampshade from the basket up. Then, they began to install it.
After they were done with their act, Ren Baqian climbed up to take a look. Surprisingly, their act was pretty good.
At first, he was a little slow, but after a few sets, he became more and more proficient. Ren Baqian felt that the learning ability of these craftsmen was much better than that of the idiots in the academy.
Twenty sets of street lamps were installed in one afternoon. Six of them were installed in front of the Yangxin Palace Hall, and the rest were installed on the road leading from the Yangxin Palace Hall to the Pingle Park.
Ren Baqian hoped that this section would at least light up first.
After he was done with all these, he entered Yangxin Palace Hall to accompany the empress and wait for nightfall.
"Are you going to the mountains in a few days?" the empress asked.
"Yeah! Salt is a big issue. I will solve it this morning. If I can't solve it, I will think of other ways as soon as possible, "Ren Baqian replied.
He wasn't sure if they could produce well salt, but he had to give it a try.
"Oh!" The empress nodded her head and didn't say anything else.
"However, from tonight onwards, the outside of Yangxin Palace Hall will always be lit up. When Your Majesty goes out to look at the stars, you won't need to carry a lantern anymore," Ren Baqian said with a smile.
Speaking of street lamps, the empress was a lot happier.
Even though there were still various differences between Dayao and Earth, she still had to take things step by step.
Looking at the gradual changes in the palace and the students learning the things that Ren Baqian taught, she felt that she would be able to see Dayao become as prosperous and beautiful as Earth in her lifetime.
"Great Xia sent out their troops today," the empress said casually.
"So fast?" Ren Baqian was a little surprised. It had only been a week since the last time the emperor of Great Xia questioned them.
Great Xia couldn't wait any longer.
"Since they have already decided to fight and are ready, they naturally won't delay." The empress wasn't surprised.
"In the afternoon, 150,000 soldiers from Tiesuo Pass were arrayed in front of Ping City. There were also catapults and other military equipment. However, General Hong Wu said that their target might be Shun City and Ziyue City. He has already ordered them to strengthen their defenses and be careful of night attacks.
As for the specifics, we will know tomorrow, "the empress said faintly.
These few days, Ren Baqian had been looking at the maps of Dayao and Great Xia. The cities and checkpoints adjacent to Dayao were mainly these: Tiesuo Pass and Ping City, Qingyang Pass and Shun City, Yunluo City and Ziyue City.
Of course, there were also large plains, mountain ranges, and valleys that connected the two countries. However, these were the main places.
If they didn't destroy these three places and came from other places, it would be very easy to be blocked. Furthermore, the logistics would also be difficult to sustain.
Therefore, if their target was the whole of Dayao, they had to destroy one of the cities to ensure a smooth route.
"General Hong Wu should be able to stop them," Ren Baqian said.
Ren Baqian didn't know much about Hong Wu, but he had been stationed at the border for decades and had an extremely high reputation. His knowledge of military strategy wasn't comparable to that of ordinary people.
He still had 30,000 aboriginal warriors in his hands, as well as drones, binoculars, and walkie-talkies provided by Ren Baqian. Presumably, it shouldn't be a problem to stop the Great Xia army for a short period of time.
The empress nodded and said, "That's natural."
Her tone was full of trust for Hong Wu.
After the two of them had dinner, Ren Baqian heard a small commotion outside. He turned his head and saw that the sky was already dark. However, it was different from the darkness of the past. There was still a certain amount of light, and he knew that the street lamps were sufficient.
"Your Majesty, let's go out and take a look. The starry sky tonight must be exceptionally beautiful." Ren Baqian extended his hand and invited the empress.
"Alright!" the empress replied with a smile.
Ren Baqian took the opportunity to hold the empress's hand and walked out. At this moment, both of them could see the light coming from outside.
When they left Yangxin Palace Hall, they saw that the guards outside were looking up in a daze. They were practically unable to close their mouths.
Previously, when these pillars were installed, no one expected them to have such an effect. After the sky turned dark, they actually lit up automatically. Furthermore, the lanterns that were commonly used in the palace couldn't be compared to them.
At this moment, there were 12 wooden pillars erected in the courtyard outside Yangxin Palace Hall. Six of the wooden pillars were emitting a white light that illuminated the surrounding scenery.
Although it wasn't as bright as daytime, the courtyard was still rather clear.
"Cough!" Ren Baqian coughed, and the four guards outside finally reacted. They turned around and greeted, "Greetings, Your Majesty!"
The empress nodded slightly and didn't say anything. She allowed Ren Baqian to lead her under the street lamps.
Ren Baqian led the empress out of the courtyard of Yangxin Palace Hall. There were still two rows of street lamps outside, but only one row was lit.
The two of them walked on this path. Two figures, one in black and one in red, slowly moved forward.
Ren Baqian was in a good mood. Dayao also had street lamps. Although they were now brought over from Earth, they would be made by Dayao sooner or later.
"The starry sky tonight is exceptionally bright!" Ren Baqian said with a smile.
The empress turned her head to look behind her, then looked in front of her and said, "It's only this distance."
The distance between the two street lamps was 60 feet, which was about 20 meters. The fourteen street lamps brightly lit up the entire road from Yangxin Palace Hall to Pingle Park. Many people in the Imperial Palace stared blankly at the road which had suddenly been lit up from afar. However, the other places were still in complete darkness.
"Very soon, it will cover the entire palace. Then, one day, it will cover the entire Dayao, "Ren Baqian said with a smile.
