When Chang'an Persia came to ask for help, Bai Fan didn't show up at all, and he didn't even have the interest to know, because he clearly knew that Persia was now coming to an end, and it would be destroyed by the newly rising Great Food Country in another ten years, how could Datang save them.

And Bai Fan has lost interest in the war to destroy the country, and he is basically nesting in the academy now and no longer going out, either teaching or doing research with many technicians.

Now what he is overcoming is how to bring Datang to the problem of the electric era, and the first step is to solve the problem of large-scale power supply.

Since the invention of the telegraph, many people in Datang have known the existence of electricity, because the telegraph is powered by silver-zinc batteries, although it is somewhat inconvenient, but it is better to have sufficient lasting power, because in Datang, the most important thing is gold and silver, since Datang began to have a money village to issue silver tickets, the people use less and less gold and silver, and the natural country has more and more gold and silver.

But if the whole country uses electricity, then it can no longer be a battery, and a power plant is needed, but the thermal power plant is too polluting, so Bai Fan considered that while Datang's demand for electricity is not so big now, it is better to start the research directly from hydropower, so he asked people to directly select a site on the river not far from the academy and build a small hydropower dam, which is only used for the academy.

"Jane, you spent half of your family fortune to get something like this? Do you have money to burn? I don't see any effect on this thing other than replacing candles. Li Jing reprimanded Bai Fan.

Bai Fan smiled bitterly for a long time, no wonder Li Jing was puzzled, in order to electrify the academy, in fact, he really spent more than half of the money, because there was no aluminum wire in Datang in this era, although there was a large-scale industry like a steel mill, if you want to manufacture aluminum wires, you must have aluminum, which is different from iron, ordinary refining will not work at all, and the extraction of aluminum can only be done if it is electrolytic aluminum, so the first power generation and power supply equipment in Datang can only use high-end copper wire.

Fortunately, there is no shortage of copper in Datang, and it is not impossible to buy a copper mine with the imperial court, but in this way, the cost is very large.

"Uncle, don't underestimate this thing, this thing can be used to replace the fire candle, how can it be so simple, with this arrangement, it is more than enough to replace the defense facilities of the academy, and it is very safe." Bai Fan said confidently.

"Just this light bulb? Are you okay to bluff people, instead of defense? Can this thing still hurt people? Li Jing and Qin Shubao shook their heads at the same time.

Bai Fan smiled secretly in his heart, directly took out two wires, and handed them to Li Jing, "Uncle might as well try it?" ”

"Hmph, try it, when I was fighting, I didn't blink when I faced the old man of the sword soldiers...... Wink、......"

Li Jing wanted to blink, but before the word came out, Bai Fan had already closed the electric switch, Li Jing began to convulse on the spot, Qin Shubao saw it, and hurriedly wanted to hold it, be careful Before the word was spoken, it was already followed by CLP.

Bai Fan hurriedly disconnected the switch, looked back, okay, you don't wait, I wanted you to take one, I took one, and then gently tapped it to try to show you, what are you doing with two wires?

Li Ji foamed at the mouth and muttered, "You, you kid, pit me?" ”

Bai Fan hurriedly helped the two of them up and explained, but there was nothing wrong with checking, both of them were martial arts practitioners, with strong physiques and no electricity at all.

"This is the defense force I am talking about, even Brother Shubao has been recruited, it seems that no one in the world can stop it."

The two nodded, it's true, if you don't feel it yourself, who would have thought that this thing is so powerful?

"In the future, I will use this electric light in the academy and Chang'an City, so that every household can be as bright as day, bid farewell to the lights, and reduce the danger of fire.

And this electricity is infinitely useful, you will know in the future, the academy has succeeded in this experiment, and I will work with Master Li Chun to build a large hydropower station on the Yellow River, the kind of large-scale industry that can supply power to the entire Guanzhong. ”

Li Jing and the others were shocked, how much would it cost to supply electricity in the entire Guanzhong? An academy has already used half of your Bai Fan's family wealth, and the entire Guanzhong has it? The two didn't dare to think about it.

At this moment, the person in charge of telegraphs from the academy came to the dean's courtyard.

"Dean, the king of Lingnan Yue is in a hurry."

Bai Fan and the three of them were puzzled, why? Is there an accident in Lingnan? Feng Ang sent a report in a hurry?

took a look, Bai Fan slapped his thigh, it turned out to be Hou Junji's matter.

Since Hou Junji destroyed the Wa Kingdom, this admiral felt that the world was invincible, and there was no meaning at sea at all, and Bai Fan had not encountered a single naval battle, so it became more and more unbearable day by day.

Later, Li Eryi gave an order, and the Lingnan departments sent troops to take the southeast of the country of Pi, Hou Junji contacted Feng Anyi, thinking that this was also a fighter, so he led the army south to help Lingnan, but he was still a little disappointed, the barbarians in the southeast were just as unbearable to beat, and they all surrendered in less than three months?

However, when he was in Lingnan, Feng An, the king of Yue, revealed a message to Hou Junji, that is, the Marquis of Lantian once said that beyond the places of the three Buddhas in the southeast, and then to the west is Tianzhu, and I heard that the Tianzhu Navy has a set.

And after Tianzhu and then to the west, I heard that the red-haired navy in the extreme west is also very powerful, these are the future opponents of the Tang Dynasty, and the Marquis of Lantian built the Tang Navy in order to defend against the invasion of these people in the future.

As soon as Hou Junji heard this, he immediately became interested and took the case, "Where is the use of waiting for a group of barbarians to attack my Datang?" Isn't that too much? Since we know that there is a country in the west, we will go directly to the army and see that one country will destroy another, isn't it the credit of us to expand our territory?

Even if you can't destroy the country, it's good to see the enemy's naval strength and know yourself and the enemy. ”

So Hou Junji ignored Feng An's dissuasion, and took his next fleet to explore the way to the west.

Although Feng Ang is the king of Yue, he leads Lingnan and can't control the admirals of the Tang Dynasty at all, so he can only send a fleet to follow the escort, and if there is any situation, he will help immediately.

As soon as Datang's navy crossed through Southeast Asia, it encountered a small group of Tianzhu country's patrolling navy, and without saying a word, he went up directly and opened fire, beating the Tianzhu navy to pieces except for a few prisoners, basically leaving nothing.

Hou Junji was furious when he saw it: "We are the Tang Navy, a regular army, not pirates, what are we doing robbing things?" It's hard to meet an opponent, and you're so humiliated? Have you forgotten all the basic respects?

Give these people a small boat, let them go back to report the news, and say that the Datang Navy will compete with Tianzhu's navy in half a month, let them get ready, wash their necks and wait at home. ”

The lieutenants are full of black lines, we are pirates? Aren't you? This is a black word that is better than all of us.
