Yang Yifei rested in the camp for a week, during which he didn't do anything, and every minute and every second was studying frantically.

A few days ago, he studied the making of potion scrolls with Akara during the day, and the recipes of those potions were not complicated, just some herb essences with healing effects, which were mixed together in a certain proportion.

And the core procedure is to use magic to extract the essence of the gem and integrate it into the potion, which requires strong memory and huge mental power as support, not everyone can do it, but this is what Yang Yifei lacks the most.

In order to study more efficiently, he also put a miniature camera on his ear during the learning process, recording all the content of his learning process, the formula ratio that Akara said, etc., so that he can read it at any time in the future, and when he returns to the overworld, he can also transfer it to the database of the Red Queen.

The formula of those potions is not absolute, it does not have to be the material of this world, as long as it has a similar effect, it can be blended, as long as its core ingredient is gem essence.

During the day, he learns how to make potion scrolls, and at night he learns the magic skills of the paladin, whose aura aura is very special and is not a consumable skill.

Opening the aura aura does not consume mana or mental power, the principle is to carve a magic array on oneself, and then this magic array will absorb magic elements on its own and attach it to oneself and surrounding teammates, causing various additional effects, enhancing attack, defense, elemental resistance, and so on.

This feeling is a bit like "enchantment", except that the object of its enchantment is a person, not an item, and you don't have to worry about it after turning on the aura, the magic array will run automatically, as long as you don't actively turn it off, the effect of this aura aura will always exist.

The so-called "protagonist aura" and "wisdom aura" in the online article are the source of the aura aura skill of the paladin in the dark world.

Paladins rely on martial arts to eat, and there are very few active magic skills, and they basically belong to light magic, so there is a saying in the dark world that paladins are born captain professions.

Its aura aura is a large area as soon as it is enveloped, and an increase is the entire team, so the paladin is usually in the middle of the overall position.

However, because of this, the paladin's skills are very simple for Yang Yifei to learn, and what took him a little time and energy is the light magic of "Holy Light Bullet", "Blessing Hammer" and "Heaven Fist".

In terms of destructive power alone, light magic is naturally far inferior to the elemental magic of mages, but its greatest advantage is that it can kill and damage spirits and undead creatures exponentially, and it has an unparalleled restraint on all dark energy.

Especially the Fist of Heaven, in the future, Yang Yifei will inevitably face the undead creatures like a sea of tides, such as the skeleton army and other opponents, a Fist of Heaven can purify a large area, more powerful than a cannonball, but it will not damage the surrounding environment like a cannonball.

In addition to attacking, the Holy Light Bullet also has a healing effect, for undead creatures and spirits, this move is a life-urging talisman, but when it hits a human being, not only will it not hurt people, but it will heal injuries and cure diseases.

It took a few days for Yang Yifei to learn to make five kinds of potions and two kinds of scrolls, Akara didn't know how to make recognition scrolls, but Dekka Kane would, they didn't have any reservations about Yang Yifei, and they were completely taught.

A few days later, Yang Yifei went to Chasy again, and he took out some of the Mithril and Magic Crystals he had obtained from Tristram and gave them to Chassi, asking her to help make more magic guide bullets.

At the same time, under the guidance of Chasi, he personally plated a semi-automatic bazooka with Mithril, and then made a large number of demonic rockets.

The effect of the Demon Guide Bazooka made Yang Yifei's heart tremble and excited, just by imagining it, he knew how perverted this was.

A full-level multiple arrow, a shell shot out, instantly turned into 21 shells, if you can learn to guide arrows in the future, ordinary bazooka seconds into shoulder-fired missiles.

Of course, there are pros and cons, using a bazooka with multiple arrows is certainly powerful enough, but the consumption of mana is also much higher than using bows and arrows and guns.

Whether it is a bullet or an arrow, it only relies on kinetic energy to kill the target, that is, the mana only needs to copy the shape of the arrow or bullet.

However, the rocket will explode, and mainly rely on the shock wave and shrapnel of the explosion to kill the target, so under the rules, the magic arrow skill of multiple arrows will play its due role, and the copied rockets also need to have this effect.

This means that each rocket is a super-enhanced version of the Burst Arrow, and its mana requirement is naturally different from that of ordinary multi-arrows or firearm multi-arrows.

According to the data obtained by Yang Yifei through the experiment, the mana consumption of multiple arrows cast with a sniper rifle and armor-piercing bullets is not much different from that of a bow and arrow, and the consumption of bursting bullets is slightly higher, about 2.6 times the consumption.

With a bazooka, the mana consumption is more than 15 times that of a bow and an armor-piercing projectile, but it is also very cost-effective, because its killing effect is far more than 15 times, which can be described as blood earning.

A week passed, everything was ready, what should be learned was almost learned, and all that was left was years of deepening practice, Yang Yifei finally took Flavi and embarked on the journey again with everyone's blessing.

……

Outside the fortress where the Blood Wasteland is connected to the Icy Plains, Akara advised: "Wright, remember that the Cold Plains have been obtained, go to the teleportation station first to record the mental fluctuations, Flavi knows where the teleportation station is." ”

Yang Yifei bowed his head and said, "Teacher, don't worry, I remember." ”

Kasha patted Yang Yifei on the shoulder and said, "Be careful, I hope you can become a living legend, not just leave a statue to the world." ”

Yang Yifei smiled dumbly, stretched out his fist and slapped her left shoulder, and said, "Your blessing is really different, don't worry!" Even if the angels and demons are dead, I will not die. ”

"It's better to be like this." Kashya laughed, then looked at it again, and continued: "Wright, I believe there are some things that Flavi has already told you, but I still want to make a formal request to you, Blood Raven...... Please help me purify her. ”

Yang Yifei said solemnly: "I accept your request. ”

After saying that, he nodded to Decca Kane and Akara and the others, and then resolutely turned around and got into his modified Wrangler with Flavi.

The so-called modification has not changed much, except that a gun carriage has been added to the rear seat position, a heavy machine gun has been mounted, the rear seat seat has been removed, and an ammunition box has been placed in the compartment, which is a chain of 3,000 rounds of 12.7 mm bullets that have been stuck in the chamber.

In addition to this, a number of rockets and a bazooka were placed as heavy fire support.

"Buzz ......"

With the roar of the engine, the fortress gradually faded away, and the car headed down the passage towards the icy plain.

On this expedition, Yang Yifei did not plan to return to the camp halfway, he had to push from the cold plain to the black wasteland in one go, and would not return to the camp until he obtained the wealth of the Forgotten Tower.

One is to report peace, and the other is to give some of that wealth to Akara to dispose of, and as the spiritual leader of the entire Rog camp, she has always been under the greatest pressure.

After all, she got too many benefits from her, and Yang Yifei really wanted to help her.
