In order to explain the knowledge of electron tubes to his Chongwen disciples, Gao Junshan stayed in the newspaper room for eight hours, and even the newspaper operator went to call for him. The telegraph operator can change shifts, so he does not feel tired of sending and receiving busy telegrams.

However, Gao Junshan was so tired that his throat was dry, because he had to keep telling the newspaper operator what he was going to report, and the capital was constantly sending him newspapers and inquiries, so it took eight hours back and forth to explain the basic principles of the electron tube to them.

After all, Gao Junshan was not born in science, and his understanding of electron tubes had only been read in popular science books, and he thought that he had passed on what he knew to his students 100% without reservation.

By the time he returned to the private room, it was already three o'clock in the morning, and the concubine Ruan Fangqing was sleeping with a dead pig, and it could be seen that she was also quite tired after playing in the sea for a day.

Gao Junshan got on the bed lightly, and then gently hugged her in his arms, she was covered by Gao Junshan's familiar fragrance, after she swam and took a bath, otherwise there would not be this fragrant body fragrance, she felt his presence, squirmed, he kissed her face, and the two gradually fell asleep......

The next day, when a ray of sunlight poured into the carpet of the private room, Gao Junshan opened his eyes slightly, and he saw Ruan Fangqing in front of a mirror, combing her green silk.

Because of the weather, she wore very little, and she was full of youth when she was less than twenty.

"Awake?" She looked back with a smile.

"yes, had fun yesterday?" Gao Junshan sat up from the bed and asked.

"Not happy."

"Not happy?"

Ruan Fangqing repeated: "Not happy. ”

"Why?"

"Because you're — not there." She dragged the word "you" for a long time.

"I'm going to take you to a fun place today." Said while getting dressed.

Ruan Fangqing asked curiously, "What place?" ”

"Go to a small fishing village called Yaman." Gao Junshan said mysteriously.

Ruan Fangqing said a little unashamedly: "It's a small fishing village again." ”

Gao Junshan said: "Don't underestimate this small fishing village, she will be the same as your hometown Cam Ranh Bay in the future, it is a great and world-famous city." ”

What Gao Junshan said is true, what he now calls the small fishing village of Yaman is the location of Bangkok in the future, the capital of Siam at this time is still in Ayutthaya, and this place of Yaman, like Pattaya, is in the hands of the Chinese army.

Gao Junshan is a traverser, and of course he will not miss the opportunity to build a city in this place of Yaman (that is, Bangkok in later life), if Yaman is built and a railway is built between Yaman and Yangon, the two cities will surely develop rapidly, and at that time, will not be golden?

Ruan Fangqing is not very interested in what the future is, she still focuses on the present, she also began to wear a coat, and said while wearing it: "I was too tired yesterday, just go too far, I haven't played enough in Pattaya, so I won't go to the small fishing village called Yaman!" ”

Gao Junshan said: "If you don't go, you can do it, just rest here, I want to go there for a field investigation, to build a city in Yaman, you must have a number in your heart." ”

Ruan Fangqing asked, "Zhou Ruozhou, are they going too?" ”

Gao Junshan said: "If you don't want to go, don't go to them, stay on the ship, and they can go to the sea." ”

So, Gao Junshan informed Sun Dahai, Liu Wenxiu, Ma Wen, Hong Pengju, Hui Yan, and Tian Qiliang to set off with him, and asked Li Derong to bring a squad of guards.

More than a dozen escorts led by Li Derong got on the first speedboat first, and Gao Junshan and his party then also came up from the suspension ladder to the second speedboat.

These speedboats on the Zheng He-class battleships are mainly responsible for the vigilance of battleships, each battleship has five such small speedboats, these five small speedboats can be docked on the deck when there is no task, and the speedboat is put into the sea when there is a mission, so his weight is only 3,000 kilograms, although it is only 3,000 kilograms, but the endurance is not low, and it is no problem to sail for 30 hours with full coal in the bottom bilge.

The speedboat is seven meters long and four meters wide, with one deck. There is only one front cabin, which is the cockpit with a crew of five.

Don't look at the speedboat is small, it has several signal lights and searchlights installed on it, but unfortunately there is no artillery installation.

After they got on the speedboat on the high mountain, they sat down on the seats on the deck of the speedboat, where there were two rows of seats for the people who took the speedboat. The speedboat's cockpit was small enough to accommodate only two sailors driving the speedboat.

The chimney towered in the middle of the deck, and when the steam engine was started, it was very noisy, and it was difficult to hear the sound on the deck, and the sailors communicated by gesticulating.

The head of the speedboat is called the captain, the rank is equivalent to the platoon commander, after Gao Junshan and they sat down, the captain came out of the cockpit and asked Gao Junshan for instructions: "Return to Your Majesty, the No. 3 speedboat is ready, waiting for the departure, please give your Majesty's order." ”

Gao Junshan said: "Let's go!" ”

"Obey!" The captain gave a military salute to the high mountain and returned to the cockpit.

Then there was a long whistle, and the rumble of the steam engine came from the bilge to the deck, and black smoke began to rise from the chimney.

The direct voyage from Pattaya to Yaman is less than 70 nautical miles, and the speedboat sails at a speed of 20 knots in the Gulf of Siam, which is now the inland sea of China, and the ships coming and going on the sea are all Chinese merchant ships, or foreign merchant ships that come to China to do business, of course, you can also see fishing boats, and occasionally there will be naval sail warships cruising.

Due to the clear weather and the sea surface is not windy and waves, such clear weather is rare in September in the Gulf of Siam, so ships come and go on the sea frequently.

After three hours of sailing at sea, the speedboat arrived at this small fishing village called Yaman, which is located at the mouth of the Chao Phraya River.

The Chao Phraya River is the main river in Siam, which originates from the glaciers of the Qinghai-Tibet Plateau at the source of the mountains of northern Thailand, and the mouth of the sea is the Gulf of Siam.

The Chao Phraya River is more than 1,300 kilometers long and has a basin area of 150,000 square kilometers, accounting for one-third of Siam's land area. The basin is an area where Siam's arable land is concentrated, and the lower plains cover an area of 50,000 square kilometers, which is now part of China.

The rivers here are crisscrossed, the climate is hot, the rainfall is abundant, the rivers flood regularly, the land is fertile, and most areas are suitable for rice cultivation, and it is known as the "granary of Siam".

When the first negotiations with King Baseton were made, there was a fierce debate between the two sides over the ownership of this area, and finally this area was assigned to the Huaxia Kingdom due to the strength of the high mountains.
