Bow and thank "Daytime Dreams" for the generous tip again.

The star core had been upgraded as early as noon when Tang Feng was eating, and was now trying to swallow the radioactive elements underground to replenish his energy reserves.

Now the energy reserve of the star core is not like the time of the primary level, and the energy reserve of the second-level star core is ten times that of the primary star core, so although the star core has been devoured for two or three hours in a row after the upgrade, the current energy reserve is only one-third.

Tang Feng clicked on the topographic analysis map, it was okay not to look at it, it was really shocking to see that the ore layer with an area of one square kilometer demarcated before the upgrade was swallowed by the star core nearly a quarter, which was far more than the energy that Tang Feng devoured in the Yeelirrie uranium mine at the beginning.

Tang Feng estimated that if all the energy storage bars of the star core were fully stored, it was estimated that at most half of this ore layer would be left.

If it was in the Yeelirrie uranium mine, Tang Feng wouldn't dare to let the star core eat unscrupulously, but here, it doesn't matter, after all, the demarcated ore layer is far away from the current Olympic Dam mining area, even if someone mines here in the future, it is estimated that it will be ten or eight years later, who the hell cares about what will happen after ten or eight years!

Therefore, Tang Feng decided to let the star core eat enough at one time here!

Originally, Tang Feng thought about leaving here this afternoon, but now it seems that it is quite necessary to stay here for one night.

In the evening, Old Keith continued to invite Tang Feng, after all, the bottle of red wine that Tang Feng took was very valuable, and Old Keith, as a ghost in wine, naturally knew this, so it was quite necessary to invite Tang Feng to dinner again, which seemed to be quite necessary in the eyes of Old Keith.

Tang Feng is not a stingy person, now he has both money and leisure, at that time in the Barossa Valley near Adelaide, he bought a dozen bottles of this top Australian wine, in order to use it when socializing with people on the road. You know, Australians still prefer red wine.

Seeing Tang Feng bring another bottle of red wine, Old Keith was a little embarrassed, but at Tang Feng's insistence, the bottle of wine was finally opened, and the beautiful old Keith was about to bubble in his nose.

For the old Case, Tang Feng still likes it, this old man himself has a cheerful personality, and he is a former peer, and there is a lot of common language between the two people, so this meal is even longer than the lunch time, if it weren't for two more self-driving tourists to stay in the hotel, this meal still doesn't know when to eat.

From Old Case, Tang Feng learned that drinking and chatting is not only a unique ability of Chinese people, but this situation is still popular abroad.

Tang Feng, who was just about to go to bed at night, received a reminder from the space, and his consciousness entered the space, and he found that the energy of the star core was full, and the star core was asking if to upgrade!

Tang Feng was startled by this question of the star core, and he drank two drinks with old Keith, making Tang Feng forget that the star core had to upgrade after absorbing enough energy! Upgrading from primary to second, and then filling the energy slot, this is a full 24 hours, and the clean area eaten by the star core on the analysis map is reminding Tang Feng how edible this guy is the star core.

This is only the second-level state, if the second level is upgraded to the third level, according to the energy demand of ten times the full energy of the upper level when the star core is upgraded, this square kilometer size of the ore layer is not even enough to upgrade the star core!

The star core is a good baby, and Tang Feng can't wait to upgrade the star core to the top level at one time, but this guy is too good to eat, and the ghost knows how many radioactive elements this guy will need to upgrade to the top level?

If it was really to continue to upgrade the star core from here, with the terrifying energy demand of upgrading from the second level to the third level, Tang Feng doubted that the star core would eat a big hole in the demarcated area.

The existence of the star core must be kept secret, so Tang Feng also knows very well that he must be careful no matter what he does, in case he leaks the secret of the star core, his fate will be crucified immediately!

Be careful! This is a principle that Tang Feng set for himself after obtaining the star core. The highest standard of behavior is not to expose the existence of the star core. Therefore, after Tang Feng weighed it, he finally gave up the idea of continuing to upgrade the star core here.

Tang Feng knew very well that after leaving the Olympic Dam, the world's largest uranium mine, it may be difficult to encounter such abundant uranium deposits in the future, and the storage energy of the star core can only rely on continuous and scattered absorption. But Tang Feng didn't regret it, because Tang Feng thought of a better way to upgrade the star core, once that method could be implemented, this bit of radioactive element in the Olympic Dam uranium mine would be nothing!

Moreover, when the star core now has the function of directly absorbing radioactive sources within a hundred kilometers, the possibility of realizing this method that Tang Feng thought of is even greater, so Tang Feng now has no worries about the huge amount of energy needed when the star core is upgraded again!

After letting the star core stop upgrading and absorbing energy, Tang Feng looked at the two meteorites placed in the space again, and then got out of the space and fell asleep on the bed.

Early the next morning, Tang Feng said goodbye to Old Keith and drove along the Lower Hill-Andamuka Highway to the small town of Andamuka, thirty kilometers away.

Andamuka is located on the east side of the Olympic Dam, almost 20 kilometers in a straight line, but the road to Andamuka is south of the Olympic Dam, so Tang Feng had to drive a little south before he could set foot on the main road to the town of Andamuka.

The reason why I want to go to Andamuka Town is that when I chatted with Old Keith last night, Old Keith reminded Tang Feng, when the two of them chatted about Australian specialties, Old Keith said directly: "It's Andamuka, 20 kilometers away from the Olympic Dam, where Australia's most famous gem - Opal." ”

As a result, this sentence immediately made Tang Feng sound the famous opal gemstone. Opal is an Australian gemstone, also known as opal, because the main source of opal is in Australia, so this world treasure is also known as opal.

This essence is a mixture of silicon molecules and water, which can be said to be one of the most beautiful gemstones in the world, Opal because of its star effect and color change effect, so this gemstone can be described as a colorful color, brilliant and colorful, a combination of various gemstone colors in one become one of the most sought after gemstones in the world.

Opal gemstones have a long history, as early as the ancient Roman times, opal gemstones were called "Cupid" by the ancient Romans, a beautiful angel in love, representing hope and purity, while the Oriental people regarded it as a sacred gemstone that symbolized the spirit of loyalty. However, in ancient times, opal gemstones were very scarce, and it was not until the discovery of opal gemstones in Australia at the end of the 19th century that opal gemstones produced in Australia accounted for 95% of the global opal gemstone market. It also gives this ancient gem another well-known name - Opal! In 1993, the Australian government designated Opal as the "national stone", making this ancient world gem a symbol of a young nation.

Opal is a very unique gemstone, each one is unique and highly collectible. Opal, with its radiant appearance, is a symbol of luck and nobility in Australia. Americans mostly prefer red and orange opals, Japanese people generally prefer blue and green opals, and Chinese people prefer festive warm red opals. Opal is a symbol of dignity and status, and the international gemstone community lists opal as the "October birthstone", a stone of hope and luck.

This time, Tang Feng went to Andamuka to see if he could get some extra money
