After Shi Leiyin completed that weird high-speed form, Shui Jing downstairs seemed to have finished the girls' chat meeting. Shui Jing unexpectedly didn't stick to Shi Leiyin, but after entering the house and saying hello to Shi Leiyin, she chose to go back to her room to sleep. Of course, she didn't give Jieliya and Zird a chance to occupy the Shileiyin brand waterbed alone, but dragged the dissatisfied Erxiao back to their room.

The next day, after Shi Leiyin greeted No. 37, he continued to sort out his abilities. However, this time, in order to test the ability, Shi Leiyin chose to go to the test area planned by the Chamber of Commerce.

It is said to be a test area, but in fact, it is to set aside a place in the secret realm for people to go in and do whatever they want. The maid of the Chamber of Commerce will set up a warning at the edge of the area to prevent others from entering inadvertently. At the same time, the Chamber of Commerce will regularly maintain the testing area to ensure that it will not be barren due to the experimental ability of the monsters.

There are many chamber test areas, and there is a fee depending on the size. The area chosen by Shi Leiyin was a large, comprehensive test area with a radius of 10 kilometers that contained a rocky mountain for testing attacks, a small lake for testing water surface capabilities, and a small sandy area.

The use of such a test area is very expensive, and there are also requirements for the level of benefits of the Chamber of Commerce. The biggest discount for Shi Leiyin's current chamber of commerce benefits is only that each application costs 10,000 points, and the time limit for use is 30 days, which cannot be used separately from the time the application is approved. However, after Shi Leiyin came back from the maze area, he directly agreed to become the master of the fifth layer of the maze, and he hadn't done any other tasks yet, so he only had a total of seventy points left on his body. Therefore, in order to rent this test area, Shi Leiyin once again became a debt-ridden slime and signed a credit loan shark with an interest rate of up to ten percent a month. For this reason, Ku was smiling from ear to ear, and gave No. 37 a third-level commendation on the spot for making this suggestion to Shi Leiyin. This made Shi Leiyin finally remember, although No. 37 is his exclusive service personnel, he is still a member of the Jinjiya Chamber of Commerce, even if he usually doesn't even give face to the library for his own sake, but when it comes to the overall interests of the Chamber of Commerce, it is definitely not negotiable.

Although it is said that the debts that can be paid off quickly have increased again, Shi Leiyin still has to do something. In fact, because he had already signed a 100-year sell-out contract, Shi Leiyin had no intention of leaving the labyrinth after paying off his debts, as Ku feared, at least, not before the 100-year employment contract expired. Therefore, Shi Leiyin didn't care if he needed to spend a year or even years of work to pay off his arrears or something. The salary of the master of the maze is as high as 800 points, and the arrears of 11,000 points can be paid off in less than half a month.

No. 37 recommended Shi Leiyin to choose such a test area, in addition to helping Shi Leiyin on the library pit, the main reason is that this kind of comprehensive test area is more suitable for Shi Leiyin's requirements for practicing his own ability.

The terrain is complex and suitable for Shi Leiyin, which is very beneficial for the production of his own all-terrain adaptation form. The rock mountain used for the attack test was the hardest rock in the Demon Realm, which was transported from the Demon Realm and was known as the 'Stubborn Stone'. This stone has no advantages other than being hard, and because it is so hard that it is almost impossible to work with any physical means, even if one stone is struck against another, it will not scratch the two stones for a thousand years. The only thing that can affect the stubborn stone is the high attack magic above the ninth order, but the people who can release the ninth order magic are only very few even in the demon realm where the strong are like forests, and letting this kind of person be a stonemason is simply looking for death. Therefore, the most that the Demon Realm uses for the stubborn stones is to use some strong adhesive to glue together the stubborn stones of different sizes to make the outermost layer of the city wall, and use their hard and weather-resistant properties to protect the city wall.

The rocky mountain in the test area is made up of a large boulder, plus a number of other rocks of varying hardness. The hard nature of the stone makes it a good target. The Chamber of Commerce only needs to replace other rocks that have been damaged by attacks at regular intervals, instead of having to find a rock the size of a hill every time.

Knowing the hardness of the stone, Shi Leiyin tried to gnaw a stone from the rocky mountain, but it was obvious that even the digestive juice that devoured the fusion slime, which can dissolve everything and even automatically develop a dissolving effect on a certain substance, has no effect on the stone. Even if Shi Leiyin asked for a very small boulder from the library and swallowed it in his body, it was useless, and the instinct to devour the fusion slime actually directly judged the boulder to be inedible and useless garbage, which was the first time that Shi Leiyin had become a slime.

However, the stubborn stone is so hard that Shi Leiyin can rest assured that he can test what he thinks is the most destructive attack method.

For Shi Leiyin, escape and defense are the two most important survival skills. Therefore, he has almost put most of his evolutionary goals in these two directions, not hesitating to create new movement forms and improve his flight ability. At the same time, he also has a soft spot for doppelgangers, which are first-class skills for playing dead and escaping. However, the so-called dog jumped over the wall in a hurry, and Shi Leiyin also considered what to do in case he encountered a situation where he couldn't escape. Desperate also has the capital to work hard, so Shi Leiyin retains the electromagnetic cannon form, which is specially used to fight hard.

After the advanced upgrade, Shi Leiyin's strength and the nature of his energy have changed dramatically. The electromagnetic cannon form that could burn half of his body with a single attack before no longer had too much impact on Shi Leiyin.

After testing the test stones of the rocky mountain, Shi Leiyin noticed that the power of the electromagnetic cannon released by the old method was still a little weaker. There were only twenty-five of the one hundred and nine test rocks in terms of hardness, and by the forty-seventh one, the cannon was completely unable to leave a mark on the rock.

This made Shi Leiyin very dissatisfied, the forty-seventh rock had only reached the hardness of Adamantite Gold, which was much worse than the jaw of the Broken Dragon. This means that Shi Leiyin was able to lay down a piece of the Broken Dragon Jaw before, but not by relying on the penetration of the electromagnetic cannon, but by relying on the impact caused by the uninterrupted impact of several shells, forcibly breaking the Broken Dragon Jaw that had a trace of flaw.

After considering this, Shi Leiyin changed to the six-tube form at that time and tested it again. However, it was immediately discovered that although this one-point attack method could shatter the test rock, it could only be said to be smashed, not broken. When the hardness of the rock reaches the eightieth block, the fixed-point continuous shooting also loses its effect. This rock is not only extremely hard, but also has a very good ability to absorb and disperse impacts, and is often used to make the walls of the city walls, which become almost indestructible when coated with boulders.
