After Tang Yong hid in the bathroom of the school dormitory, he simply did not stop doing it, and improved his physical fitness to the limit of the interstellar E-level at one time.

With the energy support provided by the mutation supersystem, the limit of the Interstellar E-class is 50 times the initial cardinality.

Promoted to this level, Tang Yong clearly felt that the essence of his life had changed, and the elemental composition of his body had added more alien energy and metal elements such as silver.

Of the 10 kilograms of silver submitted when upgrading the more frustrated and braver the system was upgraded, it is estimated that only about 5 kilograms were consumed by the system, and the other 5 kilograms were all turned into Tang Yong's body components.

Now Tang Yong feels infinite strength between his gestures, and the muscle stretching, ductility, and deformation limit of his body have changed greatly.

If Tang Yong cut his fingers at this time and let the blood flow out, he might be able to find that his blood had also changed from the original crimson to bright red with some silver-like luster.

Due to the special condition of his body, Tang Yong will no longer participate in the school's annual physical examination, and when it is time for the physical examination, he can only pretend to be sick and not participate, otherwise the blood abnormality in the body will be found to be terrible.

After the interstellar E-level body enhancement was increased to a limit of 50 times, Tang Yong began to continue to do the primary upgrade task.

When the system is in the interstellar F level and the interstellar E level, it can actually be called a "primary system", and the tasks that can be accepted are all primary tasks, and the D and C levels can be called "intermediate systems", and the B and A levels can be regarded as "advanced systems".

Interstellar E-class wants to be upgraded to interstellar D-level, which is a leap to a higher life level, realizing a huge transformation of the system from primary to intermediate, and in terms of permissions, it has been able to activate the "interstellar coordinate recording interface".

This interstellar coordinate recording interface can help Tang Yong record any point of coordinates of all stars in the solar system by consuming a certain amount of system points, and the system points consumed are determined according to the distance.

Now Tang Yong's most urgent need to record is not the coordinates of the stars, but hundreds of "infiltrator" starships disguised as "meteorites" hiding in the asteroid belt between Mars and Jupiter, ready to take advantage of the meteor showers one by one to quietly sneak into the earth.

The "Intruder" starship was almost not discovered by any scientist on Earth in the previous life, because their camouflage was too good, the surface of the starship was covered with real meteorite rock formations, and each starship carried about ten interstellar F-class alien super warriors.

Their mission is to infiltrate the earth to collect all the information about the "indigenous life" and possible "system hosts" on the earth, including the composition and characteristics of the earth's civilization, language, inheritance, etc., to help the alien civilization better understand the planet, and it is easier to win the invasion war with less consumption.

If the "Submariner" starships begin to sneak into the earth's atmosphere on a large scale under the cover of meteor showers, with their extreme speed, Tang Yong may not be able to discover their landing points on the earth in time, and the starships are very hidden, once they take root in the seabed, primeval forests or vast deserts, it will be difficult to find them one by one.

When the attention of the geoscientists to the meteor shower is gone, they will sneak out and fulfill their duties as "lurkers".

This kind of alien super warrior called "Lurker" has a very low interstellar level, only F-class, but they have a strong ability to gather information and have growth, they are a special alien Kelon life, and they are also a special kind of system host that can be mass-produced.

The only way for this "lurker" to escalate is to gather information. Tang Yong must not let them succeed.

Fortunately, the meteorite has only just appeared, and the Earth's latest meteor shower is at least a week away.

As long as Tang Yong strives to complete the system upgrade task within a week and be promoted to the interstellar D level, he can open the interstellar coordinate recording interface, and record the thousands of "lurker" alien super warriors hiding in the "infiltrator" starship across the distant starry sky by consuming system points.

In this way, no matter where they landed the starships, whether they gathered or dispersed to hide, and whether they had the means or props to change their appearance, as long as their life cores did not change, they would not be able to evade Tang Yong's search.

Tang Yong ran around for a week, and in order to complete the task, he even asked Counselor Zhang Xu for a week of sick leave, and found a four-star hotel outside to open a room for a while.

Christmas Eve on December 24th, Christmas on December 25th or something, I have nothing to do with Tang Yong, these Western festivals, in addition to sending blessing text messages with the sisters of the Fang family, Tang Yong is immersed in doing tasks.

There are 20 upgrade tasks for E-level to D-level, which is almost double the previous 10 tasks.

Some tasks are tricky, such as task 8, which requires the system host to master at least 10 languages of different countries within 12 hours.

In order to maximize the completion and rewards of the task, Tang Yong forced himself to find relevant materials, texts and audio recordings of 50 foreign languages on the Internet to study.

Despite the help of the system, he can master a foreign language in an average of 10 minutes, but this is very consuming for Tang Yong's spirit, fortunately, among the three super items that Tang Yong has, there is one called "Primary Spiritual Elixir", which can help him instantly recover all his energy and spirit, so as not to leave any sequelae such as cerebral palsy and idiocy.

For example, the 16th task requires Tang Yong to use the power of space to control more than one opponent on the premise of opening the "Space Control" skill, beat himself to the point where his life hangs by a thread, and automatically activate his "Nirvana" skill.

The task of this pit daddy should be to make the host of the frustrated and courageous system understand the complementary relationship between the three skills he has, "spatial control", "bravery" and "nirvana".

In battle, the combination of the three skills can make Tang Yong almost invincible when facing opponents of the same level.

But the question is, who is next to Tang Yong now who can injure Tang Yong, let alone beat himself to the point where his life hangs by a thread.

In order to complete this task, Tang Yong thought of many ways, and finally had to go to the market to buy a few dozen kitchen knives and fruit knives, and handed over these brother weapons to his good brother Guo Xiaopang, so that he could torture himself slowly.

You know, Guo Xiaopang is only the F-level of the system, this cheating daddy's iron buddy, his hacking system has no attack skills at all, only one programming skill, and it is also an ordinary system of a pit daddy, although it has been mutated, and his physical fitness is 5 times that of the initial base, but it is just like tickling Tang Yonglai with fists and feet.

In the end, Guo Xiaopang was in the hotel room, and with great effort, he cut dozens of brand knives produced by Yangjiang Eighteen Sons, which was able to cut Tang Yong's life to the last point.

Then Guo Xiaopang jumped up with a leap, and used the "ass sitting on the ground and falling sand and falling geese style" martial arts supreme move, only to smash Tang Yong to zero in life, activate the "Nirvana" skill, resurrect with full blood and blue, and complete the task perfectly and miserably.

After this battle, both of them were drenched in sweat and became ragged and unhuman.
