Looking at the second thing, he took out the card directly from the exclusive space.

[Premium Item Upgrade Card (One-time), which can be used to upgrade premium items once.] ］

As for the use of this card, Li Xingguo did not use it immediately, he had four equipment in his hand, namely "Sword of God Slaughter", "Eye of Truth", "Rule Shield", and "Immortal Base Armor".

Now the situation is not too anxious, he needs to study clearly, he can't use this card casually, good steel is naturally used on the blade.

Looking at the third item, a golden horn jade square, after taking it out of the exclusive space, he found that this thing was the size of a fist.

The Golden Horn Jade Square is a cube with a line of Chinese characters inscribed on it: Yang Minglang's wisdom.

"What the hell?" Li Xingguo took the golden horn jade square in his hand, and was confused by the words in front of him, Yang Minglang's wisdom, what is the use of this?

Hurriedly found the relevant manual, and after reading it for a while, he understood the purpose of this thing.

The first use is knowledge, and the Golden Horn Jade Fang stores a part of the knowledge called "Yang Minglang", and Li Xingguo can browse the knowledge stored in it.

The second use, with the help of the Golden Horn Jade Fang's Realm of Truth, allows users to use their knowledge and use the power of rules.

To put it simply, the more knowledge you have, the more powerful the power you can use.

If Li Xingguo is proficient in quantum mechanics, electromagnetism, or unified mechanics, he can even rub nuclear bombs with his bare hands, manipulate the blue star gravity field, electromagnetic field, and so on.

This is a weapon that belongs to the top students.

However, Li Xingguo became more and more strange, whether it was the immortal base armor of the first item or the third item "Yang Minglang's wisdom", there was a term that he cared about very much - new human civilization.

As a human being, Li Xingguo naturally has a certain understanding of his race.

In the temple of reincarnation, there are not a few human beings, there are human beings in the same universe as Li Xingguo, and there are also human beings in other universes.

But it was the first time he had seen a new human civilization, and it seemed that this new human civilization was very powerful, whether it was the immortal base armor or the "wisdom of Yang Minglang", these scientific and technological products showed that this civilization was extraordinary.

At least this is the strongest human civilization that Li Xingguo has ever seen.

Suppressing this matter in the depths of his heart, Li Xingguo first took out the spiral syringe containing the immortal base armor and inserted it into the artery of his left hand without hesitation.

With the injection of pale golden liquid, Li Xingguo felt that his body was slightly hot, and there was no imaginary pain, only a little numb warmth.

Soon, the immortal base armor of the spiral body syringe was injected into Li Xingguo's body drop by drop, and he felt that the power in his body was vast, as if it could tear the space in front of him.

In fact, this was not his delusion, even the power of one billionth of the immortal base armor was enough to make Li Xingguo a powerful existence comparable to a high-level creature.

Destroying at least one or two river systems is a no-brainer.

After getting familiar with the Immortal Base Armor in his body, Li Xingguo took out the high-level enhancement card and prepared to strengthen the Immortal Base Armor on his body.

[The Immortal Base Armor cannot be strengthened, and this technology product is a quasi-god-level technology.] ］

"What?" Only then did Li Xingguo realize that he was thinking too simply, it turned out that the Immortal Base Armor was a quasi-god-level technology, and it did not belong to the ranks of advanced technology.

However, in this regard, Li Xingguo's face became even more excited, and there was no way to strengthen the immortal base armor, which proved that the scientific and technological content in it was far beyond his imagination.

Since this was the case, he naturally set his sights on the Sword of God Slayer.

Originally, he planned to strengthen the rule shield, but in the process of getting familiar with the Immortal Base Armor, he found that the Defense of the Immortal Base Armor was enough to resist all attacks below the Great God level, as well as a small number of Great God level attacks, so naturally he didn't need to waste the only opportunity.

He put the opportunity on the Sword of God Slayer, and after using the advanced enhancement card on the Sword of God Slayer, the power of the Sword of God Slayer skyrocketed, and it could threaten the lives of quasi-god-level creatures.

Li Xingguo, who has both offense and defense, plus the golden horn jade square, is enough to resist many old dominators.

Ordering his subordinates to prepare lunch, he took the time to look at the battle report of the Northern Expedition.

The Great Yan Imperial Army, equipped with new rifles and artillery, was on the line of the Yellow River on the north side of Jinan City, and with the ironclad fleet that broke through into the Bohai Bay, it was more than enough to sweep Kang Mazi.

Finding that there was no problem in the battle report, Li Xingguo hurriedly ate lunch, and then checked the content of "Azathos Pseudo-God (Blue Star Chapter)".

He's ready to trouble the old rulers.

As long as he kills the five old rulers, he can get a one-month return period every year, and this temptation is naturally very great for Li Xingguo.

However, Li Xingguo is not a fool, although he wants to go back to Lanxing in parallel time and space immediately to see his elderly parents, but he still has no impulse.

He was not carried away by the sudden force, and according to the urine nature of the Reincarnation Temple, the enemies he needed to deal with were definitely not that simple.

If he rushes when he is hot-headed, he doesn't want to die before he can get out of the school, since the Reincarnation Temple has given such a powerful power, the enemy he needs to face will not be worse than him, and may even be stronger than him.

Thinking back to the last moment in the Severn Valley, if it weren't for his mental calculation and the sword of God Butcher in his hand, ten lives would not be enough for Graki to fight.

Therefore, Li Xingguo quickly suppressed his impatient mood, and while flipping through "Azathos False God (Blue Star Chapter)", he selected targets from them.

His goal is naturally to pick soft persimmons and find some weaker old rulers, although clearing these old rulers is the main quest, but the reincarnation temple will give a kill reward.
