I Picked Up Talents in the Interstellar Battlefield

First, Qin Tian decided to upgrade his skill.
The "Nether Shadow Thunder Prison Skill" was a Bronze-tier skill, which wasn't bad, but since Qin Tian had ample military merit points, he wanted to go all out.
Among the many Gold-tier skills, he chose the only dual-attribute Thunder-Dark skill, "Nine Nether Thunder Radiance Art."
The "Nine Nether Thunder Radiance Art" originated from the Gold-tier family—the Nine Nether Thunder Tiger family.
The Nine Nether Thunder Tiger family was once extremely prosperous, with many family members holding important positions within the Imperial Capital, making them a proper noble family.
Unfortunately, they chose the wrong side during the imperial power succession, which led to a tragic downfall, and their family's inherited skill flowed into the Ministry of Defense's treasury.
When cultivating the "Nine Nether Thunder Radiance Art," a Spiritual Energy User must first refine and purify the dark Psionic energy within their body, using their divine sense as a guide to construct a Nine Nether energy matrix within their meridians, condensing chaotic dark-attributed energy into a special Nine Nether Force.
The Nine Nether Force, transformed in this way, can not only hide in the shadows like a persistent bone-marrow parasite, silently penetrating enemy defenses, but also unleash extremely powerful destructive force in an instant.
At the same time, Thunder-attributed Psionic energy must be tempered through the method of Thunder Quenching the Body, giving it both destructive power and rapid speed.
This skill's Psionic energy absorption efficiency is far higher than the "Nether Shadow Thunder Prison Skill," and the Nine Nether Force and Thunder Radiance Force it refines are also high-tier energies, full of destructive power.
Skills are the foundation of a Spiritual Energy User; the better the skill, the faster the cultivation speed and the stronger the combat power.
Gold-tier skills are already top-tier among Supernaturalists; above them are only the inherited skills of the Nine Great Sacred Blood Families.
However, without sacred blood, it is impossible to cultivate sacred blood skills.
Furthermore, the attributes of sacred blood skills are not suitable for most Spiritual Energy Users.
Therefore, the "Nine /N_o_v_e_l_i_g_h_t/ Nether Thunder Radiance Art" will be Qin Tian's sole skill before he achieves great combat power; perhaps in the future, when he becomes a supreme expert, he can create a Sacred Blood-tier skill unique to himself.

Gold-tier skills are tens, or even dozens, of times more expensive than Silver-tier skills.
A single "Nine Nether Thunder Radiance Art" consumed 450,000 military merit points from Qin Tian, directly shrinking his total military merit points by nearly one-third.
However, a Gold-tier skill is worth the price.
If it weren't for the Ministry of Defense platform, even if he had more money, he wouldn't be able to buy a Gold-tier skill suitable for himself.
With the skill selected, as for martial arts, Qin Tian considered it and decided not to replace or upgrade them for now.
The reason is simple: insufficient Psionic energy. Recklessly using high-level martial arts would only lead to exhaustion after one move or self-recoil. Plus, with his current physical condition, it's indeed not suitable to cultivate new martial arts.
Currently, "Thunderclap Blade," "Ninefold Thunder Flash," and "Corrosion Hand" are sufficient. It won't be too late to exchange for Bronze-tier martial arts after breaking through to the third tier and having ample time.
For the second part, Qin Tian exchanged for two portions of seventh-tier true dragon essence blood.
Unlike the dragon blood potion he consumed before, true dragon essence blood is unprocessed; it's essence blood extracted directly from true dragon blood.
The two portions of essence blood came from a seventh-tier Nether Dragon and a seventh-tier Thunder Dragon. Under normal circumstances, these two portions of essence blood are not for human consumption,
but rather for compounding dragon blood potions or making pills.
However, Qin Tian has Night Demon bloodline, so he can directly drink the dragon blood, absorb the power within the blood, thereby strengthening his physique,
and suppressing the curse power.
The two portions of essence blood cost a total of 150,000 military merit points.
The third major expenditure was a Psionic energy equipment called the Green Sandalwood Sacred Branch Bracelet.
The bracelet is made from a branch containing the essence of divine wood, with high-level runes carved within. When worn, the divine wood essence continuously purifies the wearer, making them refreshed, immune to diseases, and also having a certain restraining effect on evil forces.
Most importantly, in an emergency, the array within the bracelet can be activated with Psionic energy, triggering the Azure Wood Barrier, which can withstand sixth-tier attacks.
After triggering the Azure Wood Barrier, the bracelet can be placed in an area rich in wood-attributed Psionic energy, such as a forest. At that time, the bracelet will automatically absorb energy to recharge, and the Azure Wood Barrier can be used again next time.
The Green Sandalwood Sacred Branch Bracelet cost 120,000 military merit points.
For the fourth part, Qin Tian spent 40,000 military merit points to exchange for a poisonous flower called the Corrupting Bone Flower. The Corrupting Bone Flower grows exclusively in the "Boneyard Tundra" at the junction of the Nether Rift and the Corrupt Abyss. This place is shrouded year-round in grayish-green miasma,
with millennia-old un-decayed bones and decaying flesh piled on the surface, forming fertile yet eerie soil. The Corrupting Bone Flower grows from this death-infused environment, with its dark purple petals emitting an eerie phosphorescence, and tiny bone worms wriggling in its pistil. Whenever a cold wind sweeps by, the petals seep out a toxic liquid with a sweet, sickly smell.
This poisonous flower is extremely potent. Once it enters the body, it will madly devour flesh and soul. Even a sixth-tier Spiritual Energy User cannot withstand it, and a seventh-tier Spiritual Energy User would have to pay a price.
For most people, the practicality of highly toxic substances is very limited.
Because it's difficult to poison a high-tier Spiritual Energy User's food without being detected beforehand, and toxins applied to weapons
cannot remain active during high-intensity Psionic energy clashes.
Moreover, how much toxin can one poisonous flower squeeze out? Exchanging tens of thousands of military merit points for a few grams of toxin is simply not cost-effective.
However, for Qin Tian, due to the existence of his Poisonous Serpent Body, he can secrete an unlimited amount of poison liquid and
poison gas after consuming the poisonous flower. Exchanging tens of thousands of military merit points for a means that can threaten a sixth-tier Spiritual Energy User is incredibly cost-effective.
For the fifth part, Qin Tian spent 20,000 military merit points, using the Ministry of Defense's channels, to have a Rune Master in the Qingmu Star Region upgrade his "Hidden Kill."
For Qin Tian, the "Hidden Kill" Rune Gun was used far more often than the black frost blade; he relied on "Hidden Kill" to snipe powerful enemies many times.
However, as his strength increased, he would soon be fighting stronger enemies, and "Hidden Kill" indeed lacked sufficient lethality against Spiritual Energy Users above the fourth tier.
Qin Tian looked at several high-level Rune Sniper Rifles, such as the Gauss Electromagnetic Rune Gun, the Pyroblast Sniper Rifle, and the Blood Demon Sniper Rifle. While these sniper rifles had strong lethality, they lacked the silent and concealed characteristics of "Hidden Kill," which did not suit his preference.
After consulting Yan Qing, Qin Tian learned that he could use the Ministry of Defense platform to ask a Rune Master to upgrade "Hidden Kill," engraving new runes to increase "Hidden Kill's" lethality to the point where it could snipe fourth-tier and threaten fifth-tier opponents.
Qin Tian did not hesitate, decisively placed an order on the Ministry of Defense platform, and sent "Hidden Kill" to Qingmu Star. Ten days later, "Hidden Kill" would return to his hands in a brand new state.
The five major parts combined totaled 780,000 military merit points.
Qin Tian rounded it off, spending 20,000 military merit points to exchange for some consumables like Lingyuan Pills, Vitality Pills, and Spirit-Cleansing Liquid, as well as 3,000 rounds of specialized "Hidden Kill" ammunition.
At this point, 800,000 military merit points had been spent.
The remaining 700,000-plus military merit points were kept as backup, which would be sufficient for future exchanges of high-level martial arts, Psionic energy equipment, or cultivation resources.
