She generously allowed the system to place her crystal core in the system space, and exchanged it for enough points to upgrade the system.
The system upgrade takes about ten minutes. Wen Yubai opened the bracelet system to check what he had gained today.
The number of monsters she killed today was less than one-fifth of yesterday's, so it goes without saying that the harvest was definitely not as good as yesterday. Today she killed a total of 37 sand spiders and only got more than 3,700 gold coins.
However, with the more than 3,000 gold coins she got today, the number of her gold coins finally exceeded 10,000.
According to the previous nature of the bracelet system, it seemed that every time the number of gold coins she obtained exceeded a single digit, the goods in the bracelet mall would explode, and many more varieties would appear at once.
Wen Yubai clicked on it and saw that it was indeed true, especially the 10,000 gold coins which was a big threshold. The items in the bracelet mall suddenly increased to four or five hundred, which dazzled her.
Because there were so many products added at once, Wen Yubai entered the bracelet mall and searched for a long time before she finally saw the premium-grade pure spiritual water as she wished.
However, ordinary-grade pure spiritual water only costs a dozen gold coins per bottle, while premium-grade pure spiritual water costs ten thousand gold coins per bottle. The price increase has suddenly jumped from the gutter to the mountain, which is hundreds or thousands of times more expensive.
Wen Yubai looked at the product introduction carefully. The dosage of the premium-grade pure spiritual water was two liters per bottle, which was twice the dosage of ordinary-grade pure spiritual water. He felt a little relieved.
Even if it was ordinary level pure spiritual water, two or three hundred milliliters of pure spiritual water would be enough for her to drink at a time. Two liters would be enough for her to drink for a long time.
Moreover, she believed that even though the price difference was so huge, as long as the energy content of the high-quality pure spiritual water was several times that of the ordinary level, it would not be very expensive.
Wen Yubai's fingers moved, and he really wanted to buy a bottle of fine pure spiritual water immediately to try its effect.
But when she looked at her gold coins again, she only had more than 12,000 gold coins. If she bought a bottle of fine pure spiritual water now, the remaining gold coins would not even be enough to buy a box of energy boxes for an intermediate safe house.
She didn't know what she would face tomorrow, and the intermediate safe house she had now was undoubtedly her best shelter. It could provide her with a temporary shelter when she faced an invincible enemy or was seriously injured.
Therefore, the most important thing for her right now is the energy box of the safe house. She must ensure that she has enough energy boxes to support the protective shield of the safe house when the situation is critical.
So even though he really wanted to, Wen Yubai still suppressed his desire to exchange for the fine pure spiritual water.
At this moment, the system that had happily upgraded to level 6 spoke and reported to Wen Yubai happily: "Host, I have upgraded to level 6. Now I can see about 10,000 meters outside the safe house. Even if I am severely suppressed in the intermediate safe house, I can still scan more than 3,000 meters."
This upgrade consumed two-thirds of her crystal core inventory. Wen Yubai smiled, but said with some pain in her heart: "Well, it's great."
"Host, it's getting dark, and it's getting a little gloomy outside. I saw that an alien adventurer has placed a safe house behind a sand dune about two thousand to three thousand meters away from us. The alien adventurer's safe house is also a mid-level safe house. Although the alien adventurer has not discovered you, the host, now, it does not mean that he will not discover you after dawn tomorrow." The system said with some concern.
This is what is called "there is a reward for every effort". If the system had not been upgraded, according to its original capabilities, it would not have been able to see the alien adventurer, and Wen Yubai's pain would have disappeared.
At this time, an hour had passed since Wen Yubai drank the Zhongji healing potion. The pain in the fractured bones was gone, and it was estimated that most of it had healed. The most important thing was that her dual abilities had been mostly restored, and now she had the ability to protect herself when she left the safe house.
Because she had used up half of her supernatural powers and suffered injuries and fractures, Wen Yubai was afraid that a third-level monster or alien adventurer would take the opportunity to attack her, so she hastily placed a metal protective shield at the door of the safe house and hid in the safe house.
The novice protection period will be over tomorrow morning. She doesn't know what kind of situation she will face, so she still has to add a layer of metal safety protection cover to her safe house like she did yesterday.
Wen Yubai came out of the safe house and it only took him more than ten minutes to set up the metal protective net.
This was because she already had experience and knew how to do it best and fastest. In addition, there were many metal balls in the space grid, so she didn't need to condense metal from the air, so her movements were much faster.
By this time, it was almost dark, and the heat in the wind had completely subsided, bringing with it a cool feeling.
Wen Yubai "looked" at the position of the alien adventurer. When she was building the metal protective net, she had been using her mental power to "observe" the alien adventurer.
The alien adventurer also set a trap outside the safe house like her. It was obvious that the alien adventurer was also a cautious one.
Wen Yubai looked at the desert that was about to become completely dark, and felt as if some deadly danger was lurking in the depths of the desert.
This feeling was not there in the previous two nights. She didn't know what she was feeling or whether she was just being too nervous.
Wen Yubai returned to the safe house and opened the bracelet system, and found that Pei Shibin still hadn't sent her a message. She was a little worried, so she clicked on the adventurer level rankings and saw that his avatar was still there.
Wen Yubai, feeling relaxed, looked at the front of the level ranking list. The alien adventurer who was ranked number three one yesterday fell off the list and dropped to second place, while another alien adventurer who was ranked number three moved up.
Adventurer No. 3 is an alien adventurer who looks somewhat like a human from the Blue Water Planet. Although he also has two eyes, a nose and a mouth, you can tell at a glance that he is an alien. He does not look as much like a human from the Blue Water Planet as the three alien adventurers No. 1.
Pei Shibin's level continued to remain where it was, neither falling nor rising, but he was able to stay in the top ten of the rankings. He must have killed a lot of strange beasts today.
Because Wen Yubai herself killed so many level three alien beasts today, but she did not improve her ranking and instead dropped two places. This shows that there were many adventurers who encountered large numbers of alien beasts. It is unknown how many level three alien beasts those adventurers killed, and whether any of them were seriously injured like her.
Wen Yubai checked the number of surviving adventurers again and found that there were only more than 89,000 adventurers. More than 10,000 adventurers had died in these three days.
At this time, Wen Yubai saw that Pei Shibin had sent her a message, and she hurriedly opened the free trade zone on the bracelet system.
Pei Shibin's message was that he had determined through preliminary calculations that the two of them were at the same latitude, with some difference in longitude. However, he spent some time adjusting his position today and had adjusted it to almost the same longitude.
