[caccaca Lake] located on the Coao plateau at the border between Bolivia and Peru, it is the highest and largest freshwater lake in South America. It is also the highest Lake in the world that allows large ships to sail!


    In a very short time, sun Cheng came to the sky over the Kaka lake.


    After two rounds of patrolling along the not small lake, he turned off the electromagnetic detection system and knew the situation below the lake.


    The lake is 3821 meters above sea level, with a water area of about 8300 square kilometers, an average water depth of 140-180 meters and a maximum depth of 280 meters.


    The city of tiawanaco, which they focus on, is located in Bolivia on the South Bank of the lake, but it does not mean that this'' Plateau Pearl ''has only this ancient relic here.


    In fact, the whole [Lake Titicaca] was a holy land in the Inca era.


    There are 52 islands in the lake, most of which have Inca architectural relics. Even many residents on the island are of Indian origin. It is difficult to say whether they are Inca sacrificial or guarding future generations.


    The largest island in the lake [Kaka Island] also has a considerable number of relics of Inca temples and palaces. However, previous pioneers have personally explored it and found nothing worthy of attention on the island.


    Of course, sun Cheng did not fully believe his judgment.


    After he found a high ground on the island and fell, he released an all terrain detector, carefully inspected the whole island, and even went deep into the bottom of the lake. After a turn, he found nothing suspicious except a small number of gold sacrifices sacrificed by Inca people in the lake for sacrifice.


    "There should be no problem in the lake. It seems that it can only be there!"


    Wandering at the bottom of the lake for a while, he wrote down several concentrated burial sites of gold sacrifices, and prepared to send underwater robots to take them away and sell them to China and Russia in the future. Then he went ashore and flew towards the ruins of [tyawanak city].


    Sprint and mora didn''t let Sun Cheng wait much. When he arrived at the site of [tiawanako city], the former obviously arrived early and was on the alert of the second-generation combat robot controlling the new offline.


    Mora stayed with several human like people, and she didn''t know what she was talking about.


    Before sun Cheng lifted the optical stealth device, the sprint obviously noticed his existence. It was only after he landed and lifted the device that he respectfully saluted: "master, everything is ready, and the underground ruins can be excavated at any time!"


    Mora also noticed this side. After whispering a few words with some startled and uncertain humans, Mora also hurried to salute.


    "Master, I have ordered to double the cordon from the original ten kilometers. The internal guards have expelled everyone around here. We will soon set up electromagnetic jammers to prevent peeping from the sky!"


    "Well done!"


    Sun Cheng nodded with satisfaction. "I just turned around at the bottom of the lake and found a considerable number of gold offerings for ancient human sacrifice in several places. It is conservatively estimated that the total amount is close to one ton. I have circled the place. You will arrange people to take out the gold in the Lake later!"


    South America is rich in mineral resources, and the reserves of precious metals such as gold and silver are even more eye-catching. It is for this reason that the Inca Empire, the once brilliant civilization in South America, is called the "golden country".


    In the era of great navigation, only one South America provided for generations of European overlords.


    Portugal, Spain, the Netherlands, Britain and even France, either dominated by colonizing South America, or rose by looting Spanish and Portuguese transport ships and merchant fleets.


    However, gold is indeed a very precious precious metal for human beings, but it is obviously not as attractive as a pile of steel for mechanical life. Even after it has developed into space civilization, steel is still an indispensable basic metal material. Compared with gold, it is obviously not as widely used in manufacturing as steel.


    Sun Cheng was also obsessed with gold. In his "spherical space", there are still two standard alloy storage boxes, which seem small, but each contains 500 kilograms of China''s standard Treasury reserve gold bricks, which he specially proposed to exchange for a set of precision equipment during a transaction with China, It has been stored in the "spherical space" by him, ready to take it back to the real world.


    However, with the No. 2 base taking control of Bolivia, several underground gold mines excavated by his forces can now provide more than 20 kilograms of pure gold every day, because more miner robots are arranged to excavate other minerals.


    I''ve seen more, and sun Cheng''s knowledge is also growing.


    Gold, jewelry and other precious things in the eyes of mankind have now become an ordinary transaction bargain for him.


    In contrast, the world''s advanced military and civilian technologies, as well as more technologies and equipment from Cybertron, have become more attractive to him.


    Mora''s eyes brightened, "master, please rest assured and give it to me!"


    He is the Minister of the interior of Bolivia. The Ministry of the interior has great power in this country. It is not too much to say that it is second only to the president.


    But power also means responsibility. In order to better control Bolivia for the base, Mora not only needs to rebuild the country''s police system, rescue and disaster relief system and public facilities, but now even some of the minerals painted in the base are state-owned enterprises legally operated in Bolivia in the name of the Ministry of interior.


    To maintain these funds, it is obvious that the government finance that has just experienced the military coup and even has a temporary name can not afford it.


    So although Mora is not human, she knows that this gold is enough to do a lot of things by herself.


    After asking sun Cheng for instructions, he went over and explained to the humans obviously under Yuri.


    Mora''s temporary departure will obviously not affect sun Cheng''s next action!


    The sprint looked at Sun Cheng. Seeing that he nodded and got the master''s order, the red light in his eyes immediately flickered.


    At the next moment, on the side of the two people, six neatly arranged excavation robots and six transportation robots vibrated together after receiving the operation command, and the scanning light like laser continued to shoot out. After the core in the head processed the terrain data just detected and made the most appropriate work plan, they began to work.
