"The two owners of this notebook are both named Victorin, they are French, they are grandchildren. The man on the bed is called Little Vic Daoan. The woman who slept on little Vic Daoan's name was Delia, the lover of little Vic Daoan, and the only daughter of the British governor living in Honsawavid at the time. ”

"Vic Dauan Sr. was a French explorer who followed the footsteps of the French government expedition along the Mekong River into the border between Hungsavady, Lancang and China, and then conspired to rob a batch of top-quality jadeite rough that the Qing Dynasty government had bought, and at the same time, stole a number of precious Chinese cultural relics, all of which were hidden in this cave."

Xu Tianyi looked at the notebook and said with an indifferent expression, "This diary is the expedition notes of Vic Dao'an's grandfather and grandson, which is very amazing, and it is a true record of the crimes of the French colonists......"

In 1540, the Portuguese explorer Antonio. Antonio de Faria first goes to the Mekong River. Although few Europeans knew about the upper Mekong Delta, a map drawn by Europeans in 1563 AD still shows the extent of the Mekong Delta.

In 1641, the Dutch merchant Glitter. Feng. Gerritvan Wuysthoff's expedition went deep into the Mekong River, reaching as far upstream as Vientiane, the capital of modern Lancang.

Although the Spanish and Portuguese had already engaged in exploratory trade and missionary work in the Mekong Valley, there was only sporadic European interest in the region at the time. It was not until the middle of the 19th century, when the French attempted to establish colonial rule in the region, that a series of large-scale and systematic expeditions were carried out on the upper Mekong.

After the establishment of the Second French Empire by French Emperor Napoleon III in 1852, the French government turned its expansion abroad. Jealous of the British's achievements in running the colony, the French tried to establish a colony in the Mekong River valley in the Far East.

In 1861, the French occupied the pheasant. On June 5, 1862, Annan's delegates signed the Treaty of Friendship with France and Spain (the First Treaty of Pheasants) at Pheasant. Under the treaty, Annam ceded the provinces of Bien Hoa (present-day Dong Nai), Gia Dinh, Dinh Xiang and Kunlun Island in the Mekong Delta to France.

Two years later, in 1863, the French forced Phnom Penh to become a French protectorate. In 1867, the French recaptured the provinces of Chao Ato, Ha Tien and Vinh Long, and called the above six provinces Cochinchine, with the capital being Pheasant. In the Second Treaty of Pheasant Sticks, signed on March 15, 1874, the Annam government officially recognized the French cession of the provinces of Chao Tuk, Ha Tien and Vinh Long.

In order to enter the Chinese mainland market, the Viceroyalty of French Indochina tried to explore the upper Mekong River to open up a "golden waterway" between Chinese mainland and Cochinchina.

In 1866, the Viceroyalty of French Indochina sent an expedition called the "Mekong Expedition" to investigate the Mekong River basin and its headwaters. The expedition consisted of 6 people, the leader was Ernest (Ernest Doudart de Lagrée), and the team members were all naval officers. Later, the deputy leader of the Mekong expedition, the Frenchman Francis Garnier, returned home and published the "Expedition to Indochina".

In June 1866, the expedition set out from Pheasantstick, the capital of Cochinchina (southern Annam), and traveled north along the Mekong River, passing through Phnom Penh, to inspect the newly discovered ruins of Phnom Penh. Then it passed through Siam and Lancang, entered China's Yunnan Province in October 1867, and then traveled from Yunnan Province to Sichuan Province, inspecting the Yangtze River Basin. Finally, he took a boat from Hankou to Shanghai, and returned to Pheasant Stick from Shanghai in June 1868.

The entire expedition lasted two years and half a month, covering more than 8,000 kilometers.

During this expedition, Ernest Doudart de Lagrée, the captain of the team, was bitten by a leech while walking barefoot in the jungle and died in the Chinese province of Yunnan in March 1868 due to a festering wound. After the expedition returned to Paris, the Expedition to Indochina was officially published in Paris in 1873.

The Mekong River Expedition spent nearly two years depicting many pictures of local customs and landforms, which can be said to be fine and accurate, and have high historical value. On the other hand, the expedition explored a wide range of topics, including the history and geography of the Mekong River basin and the local cultural customs, as well as the hydrology and meteorology of the Mekong River.

Along the way, they produced a series of maps of great military and scientific value, mainly covering the three countries of Indochina, as well as the Chinese province of Yunnan and the Yangtze River valley.

Beginning in 1893, France extended its influence along the Mekong River to Lancang, establishing French Indochina in the early 20th century, and it was not until after the First Indochina War that French influence in the Mekong basin ended.

The publication of The Expedition to Indochina in February 1874 sparked a strong interest in the Mekong River basin among European colonizers. The French explorer Victorin the Elder (Victorin, the grandfather of the Victor in the grave), with the support of two major European conglomerates and the French government, organized a powerful expedition of 72 people. They set out from Pheasant, the capital of Cochinchina, and headed north along the Mekong River.

On May 11, 1875, it was noon when the expedition arrived near Vientiane in Lancang.

While the fleet was approaching the dock, a serpentine with green scales, three or four meters long with a bare head, suddenly appeared on the surface of the water, with eyes like two crystal pearls, but soon burrowed into the Mekong River and disappeared without a trace. At that time, almost all of the team members witnessed the giant monster, and Victorin recorded its image and the situation in his diary in detail.

"A huge black snake of thirty or forty or fifty meters, the body of the snake may be as thick as a few people, and its whole body is covered with dark green or black scales, smooth and crystalline, shining, like metal. It looked at us, its eyes dark and bright, as if it were thinking about something. Soon, it was under the Mekong River and disappeared. I'm sure it's what the locals call Naga, the most amazing animal in the Mekong! ”

The appearance of Naga caused the expedition to encounter its first serious crisis.

In the evening, the expedition tied up six Annamite prostitutes brought from the city of Pheasant, the capital of Cochin, and brutally threw them into the river amid their screams. They wanted to use these prostitutes, who were tired of playing, to attract Naga's attention. The other part of the expedition team snatched eleven Lancang girls from Vientiane City after going ashore and were about to take them to the deck for dinner and carnival.

That's when disaster struck.

The surface of the Mekong River, which is usually calm, suddenly has rough waves, splashing waves, and a tall column of water rises into the sky, and this big snake hula from the bottom of the water and floats to the surface of the river. Instead of devouring the prostitutes struggling in the river, it began to attack the expedition's ships in a frenzy.

It stretched out its huge tail and directly wrapped itself around the outermost boat, pulled it over, and all the members of the team on the boat fell into the water and were swallowed by the big snake one by one. It began to attack the second boat, then the third boat, and then swallowed all the overboard team members into the bloody mouth.

Due to the suddenness of the incident, the team members on the ship and the team members on the shore were all blinded. It wasn't until it began attacking the fourth boat again that Vic Daoan and his crew remembered to take up arms and return fire. The light and heavy firearms were fired at the same time, and the big snake sank into the water and disappeared without a trace in an instant.

By this time, it was already dark, and night had come.

The expedition was badly damaged, five boats, three were wiped out, and only twenty-one members remained. Of the Annan boatmen who were brought on board from Pheasant City, there were only five people left. In the darkness, everyone held their guns and aimed at the black river, their hearts full of fear, not knowing when Naga would attack them again.

Vic Daoan immediately ordered all the captured Lancang girls to be released, all the personnel went to the shore and put ropes on the ropes, and the remaining two boats immediately went upstream. It was only when I left Viet Chern and arrived at the Nam Oh River Reservoir that the wind direction changed. They immediately set sail and fled, and it was only when they fled to Rambrabang that everyone's hearts calmed down a little.

When they arrived in Rambrabang, they were still in shock and rested for a week.

Next, according to the description of the "Expedition to Indochina", the expedition team followed the Nam Kham River to the source, and finally entered this large karst cave under the Prée Mountain from the entrance of the cave.

After a period of exploration and exploration of the Great Cave, Vicdaoan could no longer walk. The strange geographical structure and the unexpectedly magical space made him decide to build a permanent underground fortress here.

For the next three years, Vicdaoan and his expedition team did not leave here for half a step. With the covert support of the Viceroyalty of French Indochina, they built a massive, impregnable underground fortress at the foot of a mountain.

A huge drug processing plant was built in the underground base, funded by two major European consortia, and large-scale purchases of opium poppy plant capsules from the five countries of Lancang, Hungawaddy, Annam, Siam, and Khmer, and secretly processed and refined them here for modern processing and refining to turn them into opium and heroin and sell them to the world.

"That's how this underground base came about. So, what is the deal with all this wealth? How did the French and the M people fall out? ”

Lin Tao asked in surprise, and the others were also staring at Xu Tianyi.

Xu Tianyi said, "According to the notes, these riches were looted from China, and there should be more remarkable ancient Chinese cultural relics and treasures in the cave underneath." ”

In November 1898, a French missionary, carrying a letter from the governor of French Indochina, accompanied by a group of local Hmong armed guards, came to the base to find the elder Vic Dauan.

It turned out that two French "missionaries" and a British "missionary" joined forces with Fu Ying, an official of the Qing Dynasty government in China who was responsible for the mining and transportation of jadeite and jade, to find and excavate a royal tomb of the ancient Nanzhao Kingdom and two royal tombs of the Dali Kingdom located under the mountains of Yunnan Province, China, in the name of jade mining.

The ancient Zhao Kingdom and the Dali Kingdom are two powerful and magical dynasties in Chinese history, and their royal tombs are built very hidden. It is said that the royal tomb is hidden deep in the mountains, and those who know it are all gone, and it is difficult for future generations to find a trace. Ke Fuying is a jade master who has learned through five cars, and is well versed in civil engineering and feng shui gossip. The three "missionaries" are actually professional treasure hunters, and when they are entangled together, it is naturally not difficult for miracles to occur.

The priceless national treasure has reached their hands in this way. In order to hide their crimes, they also brutally blew up the royal tombs after sacking, so that their traces completely disappeared from the earth......
