This manor is obviously not the manor where Mr. Sigman often lives, because the owner of this manor is none other than Mr. Sigman's eldest son, Diego. Sigman.

For the sudden arrival of his father, Diego. Sigman was visibly pleasantly surprised. Over the years, this old man has rarely shown up, usually either staying on the farms in the northern provinces, or going to the southernmost island of Tierra del Fuego to fish, this time he suddenly came here, which made Diego. Sigman was surprised.

"Don, this is my eldest son, Diego. Sigman, you can call him Diego. Diego, this is Mr. Tang, whom I have often told you about. "The old man personally served as the introducer.

Tang Feng and Diego shook hands, Tang Feng smiled and said, "Nice to meet you, Diego, I am Tang Feng, you can call me Tang." ”

The eldest son of Mr. Sigman, a middle-aged man in his forties, looked quite calm, and looked seven points like his father, Hugo. Sigman.

Tang Feng knew that the middle-aged man in front of him had now taken over almost all the business in his father's hands, was responsible for taking care of the entire family's business, and was the ironclad successor of the Sigman family.

After a few pleasantries, Diego began to welcome dinner. A big man like them from an aristocratic background, who pays great attention to etiquette, Tang Feng can become a big man who needs to be befriended by his father, Diego, as the son of Mr. Sigman, the owner of this villa manor, naturally has to hold a rather grand welcome dinner for Tang Feng's arrival, so as to reflect his respect for Tang Feng.

Tang Feng knew that this was someone's kindness, so he accepted Diego's kindness. However, Mr. Sigman looked really tired, and after a few sentences, he went straight upstairs to rest.

As the richest man in Argentina, you have to hold a welcome dinner. Although the time was a bit rushed, more than 20 local dignitaries rushed in person, including the mayor of La Plata, and several members of the provincial legislature.

To be able to gather those local bigwigs in such a short period of time, it is estimated that the Sigman family has the ability to do so.

The atmosphere of the dinner was quite good, especially for the Buenos Aires provincial legislators. After hearing that Tang was planning to join forces with the Sigman family to build a large-scale integrated oil refinery in the southern region of the province of Buenos Aires, they all showed great enthusiasm for Tang.

When these parliamentarians learned that Tang Feng's hometown was actually Lu Province in China, these parliamentarians showed even more affection, because Buenos Aires Province and Lu Province in China are friendly provinces. In the middle of the dinner, Mr. Sigman came downstairs to meet with the councillors and the mayor of La Plata, and showed enough respect for Tang, and the politicians looked at Tang Feng in the same way that they looked at their own father.

The political situation in Argentina is actually quite chaotic. If these politicians want to go up, they need the support of a super-rich like Sigman, and without financial support, these sub-politicians are nothing. Therefore, the young rich man who suddenly appeared naturally became a sweetheart in the eyes of these politicians.

The dinner was held until ten o'clock, the atmosphere was very good, and Tang Feng also gained a lot of promises.

Tang Feng stayed in the manor at night, and one of the four auxiliary villas became Tang Feng's guest room.

Early the next morning. Diego. Sigman personally brought a large stack of materials, which had been copied overnight from the archives of the Argentine Marine Administration. It was full of detailed information about the continental shelf off Argentina that Tang needed.

These materials are not something that ordinary people can see, this is almost the core information of Argentina, if it were not for the Sigman family himself, it would be impossible for Tang Feng to obtain such detailed information.

After breakfast, Mr. Sigman, who had had a good night's rest, sent Tang Feng to the Riva yacht in good spirits. The yacht was bought by Diego just last year. Now Tang Feng needs to use a yacht, so using this yacht as a vehicle for Tang Feng's sea trip is completely in line with Tang Feng's identity.

The 115-foot Athena, while not as large as those megayachts, is more than adequate for surveying the offshore continental shelf. And Riva Yachts is a well-known yacht brand known as "Rolls-Royce of the Sea". The yacht builder's more than 170-year-old yacht makes Riva yachts unrivalled in terms of quality and ride comfort.

To the north of the manor is the waterway leading to the Atlantic Ocean, and Tang Feng took the two bodyguards, the hyena and the bear, to board the yacht called "Like a Leaf". It would take at least ten days to go to sea, so Mr. Sigman would not follow. It was useless for him to go along, except to increase his fatigue in vain, it really had no effect.

Of course, the captain, chief engineer and attendants on the yacht are all fully equipped, and there is no need for the three of them to worry about driving matters, they only need to lie on the sofa in the cabin or bask in the sun on the deck.

After the silver-white yacht emerges from the waterway, it enters the mouth of the wide Rio de la Plata, which is one of the top three in the world, because the area of this estuary alone is 130,000 square kilometers, far exceeding the mouth of the Amazon River. It's a bit inappropriate to call it an estuary, but it's more appropriate to describe it as a bay.

As soon as the beautiful "Like Leaves" enters the mouth of the Río de la Plata, it begins to increase its speed, and the Athena, a large yacht built by Riva Yachts, can reach a top speed of 27 knots, even at a cruising speed of 23 knots.

With the surging power provided by the two engines, the speed of the Leaf was quickly increased to cruising speed, but even with the cruising speed, it took more than three hours for the Leaf to sail out of the waters of the estuary of La Plata and into the Atlantic Ocean.

Argentina has one of the world's best continental shelves, the continental shelf north of the mouth of the Rio de la Plata, which belongs to the territorial waters of Uruguay, is only about 100 kilometers wide, but in the Argentine territorial waters south of the mouth of the Rio de la Plata, the continental shelf here ranges from 200 kilometers wide to 300 kilometers, and as for the southernmost eastern continental shelf of Tierra del Fuego, that is, the Scotia Ridge, it even extends eastward to South Georgia, which exceeds more than 1,500 kilometers!

Tang Feng's mission is to open the exploration function of the star core in this huge continental shelf sea area and find a geological trap with oil and gas resources! (To be continued.) )
