As soon as his heart moved, the dantian true yuan gushed out, poured into his right forearm, and filled towards the magazine, and there was a golden light flashing in the magazine.

After a dozen breaths, ten solid warheads with golden light, condensed by the energy of Gengjin, connected to eggshells filled with true yuan, were freshly baked. And it is formed directly in the magazine, and even omits the reload.

Hua Xia Jiu did not shoot immediately, but after a period of detailed reasoning and calculation in his mind, he made some modifications and adjustments to the construction principle of the pistol on his left arm.

After doing these things, Hua Xia Jiu looked expectant, raised his left arm, and hit the stone door of the secret room without hesitation.

Hum――――

A slight cracking sound sounded.

The white light on the stone door of the secret room suddenly appeared, and the protective formation reacted autonomously, and with a snort, a finger-thick hole appeared on the stone door of the secret room, and Hua Xia Jiu's soul consciousness attached to the Gengjin warhead, and clearly detected that after the Gengjin warhead passed through the stone door, it shot through the corridor wall and entered a rockery in the courtyard.

As soon as Huaxia Nine Soul Consciousness moved, the Gengjin warhead exploded directly, turning into hundreds of Gengjin hair needles as thin as a hair and shooting in all directions.

The sneering sound continued, the rockery did not explode, only the Gengjin bullet exploded with a fist-sized spherical inner cavity, but on this hollow spherical stone wall, there were hundreds of holes as thin as hair, how deep the hole was, as long as you look at the outside of the rockery after the snort, hundreds of fine dust shot out, you can understand.

Huaxia Nine Soul Consciousness was withdrawn from the courtyard, and watched the holes in the white light flickering of the stone door of the secret room continue to heal, and the stone door was unexpectedly intact for a few breaths.

While he was surprised by the subtlety of the prohibition of the stone gate protective formation, he began to frown and think deeply about the lack of Gengjin bullets.

The power of the Gengjin bullet was a little stronger than he expected, but he was still not very satisfied, especially since the shooting speed was already much faster than the attack speed of ordinary long-range spells, but if he used a sniper rifle to shoot at a long distance, this speed was enough for the opponent to detect in advance and calmly dodge.

The principle of the entry, firing, and firing of the heptane bullet is naturally very different from that of the earth's gunpowder weapon, and he has already made modifications and adjustments to this just now.

However, judging from this situation, further research and transformation are needed.

For example, reduce the sound of the Gengjin bullet rubbing air during high-speed movement, find a way to use the soul sense to control the sudden change of the trajectory of the Gengjin bullet during high-speed flying, add other components to the Gengjin bullet to increase the lethality, and so on.

Huaxia Jiu's mind is running at high speed, and he is doing his best to reason and calculate.

A moment later, while Hua Xia Jiu's left arm was wriggling, the pistol structure was once again modified and adjusted. The nine remaining heptane bullets in the magazine have also undergone some modifications in the flash of gold.

Hum――――-

The sound of breaking the air sounded much weaker than just now, and another Gengjin bullet shot out, hitting the stone door of the secret room.

In the flickering white light, after the snort, an explosion sounded in the courtyard, and a piece the size of a skull on the rockery exploded into powder.

Compared to just now, the speed of the heptangium bullet has increased by a quarter, and the sound of high-speed movement has weakened a lot, especially after adding some true elements to the heptangium warhead, the power has increased significantly.

However, Huaxia Jiu was still not satisfied, and after collecting accurate data from all aspects, he started a new round of research, reasoning, and calculation again. In particular, the question of the trajectory change of the heptyl bullet has not been resolved.

In this way, nine days passed before I knew it.

Hua Xia Jiu studied pistols in the first three days, sniper rifles in the middle three days, and machine guns in the next three days. During this period, each gun shape has undergone hundreds of research, modification and test firing, so that the speed of the Gengjin bullet has been greatly improved, and the power has increased significantly, especially when flying at high speed, the sound has almost reached the level that is difficult to capture by the naked ear.

In addition, after unremitting efforts, Hua Xia Jiu was finally able to change the trajectory of the Gengjin bullet during its high-speed flight. But because the Gengjin bullet flew too fast, he could only barely or in time to change the orbit once.

In fact, every ** squirming, as well as every shot of a heptyl gold bullet and the friction of the flesh that turns into the barrel, will bring extreme pain. In this regard, Hua Xia Jiu did not frown from beginning to end, as if he really regarded this as a weapon, not his **.

Even, for the research of this new type of attack, he feels that there is still a lot of room for improvement.

But there is no time for the time being.

This evening, he will meet with the Iron Demon and go to the Dayan Mountains together. In the meantime, he still has some things to do.

Hua Xia Jiu's arms returned to normal, changed into a cyan robe, and then left the courtyard and walked towards the front building of the Dayan Inn.

When he went to the front floor of the inn, he saw that someone was eating, and for some reason, he suddenly felt a great increase in his appetite, so he found a secluded place to sit down, ordered a table of food and two jars of wine, and began to eat and drink.

Hua Xia Jiu was originally a machine, and every time he saw human beings eating with relish, he was a little envious. Later, although he was transformed into a human body, because of various crises, he was busy improving his strength, and the monk himself because of the aura into the body, endlessly, without eating, ** can operate normally, so he has never enjoyed the taste of human food.

So, this was the first time he had enjoyed human food, and it wasn't an ordinary human food.

Dayan City is a city of Xiuzhen, and Dayan Inn is the most high-end consumption place in Dayan City, how can it be compared with ordinary food.

With all kinds of expensive spiritual materials and aura, bloody demon beasts**, the various delicacies cooked were constantly placed in front of Hua Xia Jiu, he smelled the tempting fragrance, and unabashedly flowed out of Halazi.

He began to eat, he began to eat heavily, he began to eat without hesitation, as if no one else was around.

Hua Xia Jiu's meal came out in an earth-shattering way.

As the top inn in Dayan City, most of the people who can live here are out of body realms, and there are very few low-level monks in the Huadan realm like Huaxia Jiu, after all, there are probably less than one in ten thousand as rich Huadanjing monks like Huaxia Jiu.

At this time, there were more than a dozen monks sitting on the first floor, all of whom were cultivators of the out-of-body realm, and there was even an out-of-body consummation powerhouse. Most of these people are drinking alcohol or tea, and they don't eat much.

Hua Xia Jiu had a meal for the first time, although he easily learned the basic actions of using chopsticks to pick up vegetables and drinking soup with a spoon through memory. But it still looks a little stiff, or weird.

Especially as he tasted the deliciousness of the food, he ate and drank faster and faster, and the sound he made became louder and louder.

It didn't take long for him to receive the attention of the audience, and more than a dozen monks watched in amazement as he devoured him.
