Li Jiaxing deserves to be the most powerful mathematician in the world, although it took some effort to recruit him at that time, but it is definitely worth the money!

When Qiao Tianyu woke up in the morning, Li Jiaxing had already studied the cracking method, and when Qiao Tianyu got the fax of the calculation results, his heart was suddenly steady.

It's exactly the same as the memory of his previous life, and sure enough!

Qiao Tianyu finally showed a knowing smile on his face, in today's battle, Qiao Tianyu has won 80%, as for the remaining 20%, he can only do his best to obey the fate of heaven!

There is no need to worry about the matter of LTCM, Qiao Tianyu just made a phone call to Henry and explained how to operate it.

Next is OPEC, which is also Qiao Tianyu's top priority today.

To solve the problem of OPEC's oil policy, Saudi Arabia is naturally the key to the key, so today Qiao Tianyu must go out in person and go to Riyadh in person!

Fortunately, in the 90s, Saudi Arabia, the United Arab Emirates, Qatar, Kuwait, Oman and Bahrain and other Gulf countries implemented a visa-free policy, that is, as long as you hold a visa at the engineer level or above in any country, you can enjoy the free entry and exit treatment of the six Gulf countries.

Speaking of which, thanks to Palizovsky, a week ago, Qiao Tianyu entrusted Palizowski to help with the visa of the United Arab Emirates, Palizowski seemed to have a premonition that Qiao Tianyu might have to wander around other Gulf countries, so he helped Qiao Tianyu and others apply for engineer visas.

Therefore, under Palizowski's "foresight", Qiao Tianyu was able to take Andre in and out of Saudi Arabia without hindrance.

As for the chubby face, it's better to stay at home and raise the baby.

Hearing that Qiao Tianyu was going to Saudi Arabia to solve the problem of OPEC's oil policy, Qiao Dahua immediately became attentive, and quickly spent a lot of money to rent a helicopter to carry Qiao Tianyu and Andre to Riyadh, the capital of Saudi Arabia.

However, after coming to Riyadh, Qiao Tianyu did not go directly to the magnificent and luxurious Saudi palace, after all, Qiao Tianyu is an ordinary man here, and it is a fool's dream to enter the palace, so Qiao Tianyu came to a skyscraper five kilometers away from the palace.

However, this skyscraper is obviously not an ordinary office building, and the inside and outside of the office building are guarded by heavily armed soldiers with guns, which frightens ordinary people to retreat and dare not approach at all.

Qiao Tianyu and Andre also stopped at a distance of fifty meters from the building, and conducted a careful interrogation and identity check.

However, when they learned that Qiao Tianyu wanted to meet the owner of the skyscraper, Prince --- Saltu, chairman of the Saudi sovereign wealth fund, the scene immediately became tense.

More than a dozen heavily armed soldiers surrounded Qiao Tianyu and Andre, and more than a dozen black guns were instantly aimed at Qiao Tianyu and Andre, with a rhythm of wanting to beat them into a sieve.

"Cut, it's really like that!" Qiao Tianyu chuckled, took out the business card from his pocket and handed it to the soldier at the head.

"You give this business card to Prince Saltu, whether you want to see me or not, he has the final say!"

Sure enough, not long after the business card was handed over, the soldier at the head ran back breathlessly, put on a grinning face, and said that Prince Saltu was invited.

Under the guidance of the leading soldiers, Qiao Tianyu and Andre took the sightseeing elevator directly to the 77th floor of the building--- where Prince Saltu's office is located.

In Saudi Arabia, "7" is the most noble and auspicious number, similar to the number "9" in the minds of the Chinese, so as the owner of this skyscraper, Prince Saltu chose the 77th floor as his office.

When the staircase door on the 77th floor opened, a middle-aged man in his fifties dressed in a traditional Middle Eastern white robe greeted him warmly.

However, when the other party found out that the person who came was not the owner of the business card at all, but Qiao Tianyu, his face suddenly changed.

Joe ..... Qiao Tianyu: How could it be you?"

Yo he, you actually know that I am Qiao Tianyu?

This made Qiao Tianyu a little flattered.

It seems that Qiao Tianyu's reputation in the Middle East is still quite big!

"Haha, Prince Saltu, don't you welcome me Qiao Tianyu?" Qiao Tianyu smiled slightly, and took the initiative to stretch out his right hand to Andre.

Prince Saltu, son of the elder King Ibn Saud, is the former Saudi plenipotentiary to OPEC and the current chairman of the Saudi sovereign wealth fund, and the 10th in line to the Saudi throne.

As for the sovereign wealth fund, it corresponds to private wealth, which refers to the public wealth accumulated by a country through specific tax and budget allocations, balance of payments surpluses, etc., controlled and controlled by **, and usually held in foreign currency.

To put it bluntly, a country's sovereign wealth fund is the country's national fund team, and its main role is to maintain the security of the country's financial market, exchange rate, trade, etc.

It is precisely because of the national team nature of sovereign wealth funds that the scale of sovereign wealth funds is generally very large compared with private funds.

According to statistics from the International Financial Services Authority (IFSL) in London in March 2009, global sovereign wealth funds managed $3.9 trillion in assets in 2008, of which Middle Eastern oil-producing countries owned 45% of global sovereign wealth funds.

According to a report released by the Washington-based sovereign wealth fund research organization in 2013, Norway** Fund topped the list with total assets of $804 billion, Saudi Arabia's sovereign wealth fund ranked third with assets of $627 billion, and China ranked fourth with assets of $575 billion.

Therefore, it can be seen that Prince Saltu is in charge of another very important economic wealth lifeline of the Saudi royal family, and the degree of prominence can be imagined.

"What are you doing here?" Prince Saltu seemed to welcome Qiao Tianyu's arrival, ignoring Qiao Tianyu's outstretched hand, and had no intention of shaking hands at all.

"Of course I'm here to save you!" Qiao Tianyu said with a smile.

"Help me?" Prince Saltu scoffed, "Joke, I'm the Prince of Saudi Arabia, in charge of the world's second-largest Saudi sovereign wealth fund, why do I need your little cub to save it?"

After saying that, Saltu glanced at the soldier behind Qiao Tianyu, and the soldier understood it, and he stepped up and put his hand on Qiao Tianyu's shoulder.

Qiao Tianyu understands that if he dares to take another step forward without authorization, I am afraid that this arm will not belong to him in the next second.

"Haha, Prince Saltu, since you are so confident, why do you care so much about the people in the business card, and bother your old man to go out to greet him in person?" Qiao Tianyu said with a smile.

"You ......," Prince Saltu choked on for a long time.

He lowered his head and thought for a while, but finally waved his hand, bowed the soldier, and walked into his office with Qiao Tianyu......
