Half a year passed in a hurry, and during this time, Qu Yue was immersed in crazy refining!

Since learning that Hongyu's body can be healed, He Zhan's state has recovered well, his smile has increased a lot, and even his walking has become much lighter, and his whole person's spirit has changed a lot, and he looks as if he is more than ten years younger.

In the past six months, He Zhan has spared no effort in teaching Qu Yue, not only teaching his many years of refining experience, but also packaging the secret books of refining in the sect into a book and handing them all over to Qu Yue.

During this time, Qu Yue's life can be described as like a fish in water, and there are several piles of refining materials like a hill.

With the help of He Zhan, Qu Yue used these materials to completely transform the "Vientiane Treasure Box", and the current "Vientiane Treasure Box" is truly worthy of the word "Vientiane".

The space inside the treasure box has been expanded several times after the use of the Small Sumeru Stone, and it can carry more weapons.

Taking advantage of the heat-resistant properties of "Cold Gold", Qu Yue used it to forge two fully automatic pistols. Both pistols are available in single and burst shots.

Needless to say, a single shot can reach a rate of fire of 500 rounds per minute when fired in bursts, which has completely replaced the previously prepared machine guns.

If the pistol is combined with the Vientiane Treasure Box, either of the two pistols can fire at the rate of fire of the machine gun without interruption using the auto-reloading device.

As for ranged strikes, a fully automatic sniper rifle was created using Flame Blaster.

This kind of sniper rifle uses mainly "spiral air secondary acceleration bullets". This kind of bullet was developed by Qu Yue based on He Zhan's refining experience. It was the appearance of this kind of bullet that realized Qu Yue's idea of accelerating the discharged bullet for the second time.

The spiral bullet and the spiral barrel made of Flame Iron make this sniper rifle greatly increased in range and power. According to experimental data, the effective range of this sniper rifle can reach more than 10,000 meters.

As for the power, as long as it is not the cultivation of the foundation building period, it is certain that it will be finished with such a shot. Even if He Zhan's strength in the "early stage of foundation building" used spiritual power to defend, he could only be stopped. Of course, this is in the case that He Zhan does not use magic weapons.

Qu Yue was already very satisfied with this effect, as a sniper, the main means of killing the enemy was to be surprised. In the case that the other party was unprepared, Qu Yue believed that even if the cultivation of the foundation building period came like this, it would be enough for him to drink a pot.

Of course, with such a big killer weapon in hand, of course Qu Yue would not only use "spiral acceleration bullets", he also made some "sniper burst bombs".

It is similar in structure to Earth's "instantaneous bomb", but more powerful.

The reason why the bursting bomb is called a bursting bomb is because inside the warhead, an air bursting device newly developed by Qu Yue is placed. At the moment of impact, the warhead explodes instantly, creating a powerful impact, and it is with the power of this shock wave that it shatters everything that stands in his way.

However, the blasting bullet uses a special material and cannot be accelerated twice, so after replacing this bullet in the sniper rifle, the effective range is only about 3,000 meters. Because of the abandonment of the distance advantage, the power of the burst bomb is several times higher than that of the spiral bomb.

He Zhan had used spiritual power to urge the defense magic weapon to test. The defensive magic weapon was shattered under the bombardment of the bursting bomb, but fortunately, He Zhan reacted quickly enough, otherwise he would definitely be injured!

As for other types of ammunition, such as "armor-piercing bullets" and incendiary bombs, they were not very useful for entering the Silent Annihilation Realm, so Qu Yue only prepared some hastily and did not put too much thought into them.

In terms of throwing weapons, Qu Yue also spent a lot of thought.

The "high-explosive grenade" with a lethal power of 50 meters in diameter, the "Sun Flash Grenade" with impact mental energy, the "Miasma Smoke Bomb" to prevent the detection of mental power, and the "Poison Tear Gas" made with poisonless substances, etc.

At the beginning, He Zhan could still use himself as a target for Qu Yue's experiment, but the moment the first high-explosive grenade was made and successfully exploded, He Zhan was frightened by the scene in front of him, and his legs were weak, and he sat on the ground stunned for a long time, saying that he would not use Qu Yue as a target for the experiment!

When He Zhan experimented with the various weapons developed by Qu Yue, he was simply dazzled, and he couldn't help but secretly evaluate Qu Yue's "perversion" in his heart! However, He Zhan was very satisfied with this effect, because he knew that Qu Yue was about to enter the Realm of Annihilation.

Although He Zhan had never been to the Silent Annihilation Realm, he learned about it from the master. Although the Silent Annihilation Realm can suppress anyone's cultivation in the condensation period, there are still many unknown dangers inside. Those who enter the treasure hunt are often only three or four percent of them who can survive. For this reason, he had dissuaded Qu Yue more than once, but every time under Qu Yue's confident and firm eyes, he reluctantly gave up.

It was precisely because of this that He Zhan deeply felt that his father and daughter owed Qu Yue too much, so he spared no effort to help Qu Yue make weapons to improve his strength, thereby increasing his chances of survival.

In half a year, Qu Yue not only made amazing achievements in refining weapons, but the speed of cultivation was also staggering. Now his cultivation had reached the sixth level of the Qi Condensation Stage.

After cultivating to reach the sixth layer of condensation, Qu Yue obviously felt that his body had greatly improved his strength and reaction speed compared to before, and although there was still half a year to make progress and the bald bird's request for "nine layers of condensation", Qu Yue still had a deep sense of urgency.

"Click!!" Qu Yue put the completely renovated "Vientiane Treasure Box" behind him.

The treasure box contains two 5.6 mm caliber automatic pistols, a 25 mm caliber automatic sniper rifle, hundreds of high-explosive mines and various grenades, and countless bullets.

At this time, the "Vientiane Treasure Box" is inlaid with a small Sumeru stone with its own space, although the size is the same as before, but the weight is much lighter, otherwise the weight of many ammunition alone is enough for Qu Yue to drink a pot.

After careful consideration, Qu Yue decided to go to the back mountain to look for the bald bird, hoping to get a chance to break through.

Qu Yue had already cultivated to the sixth layer of Qi Condensation two months ago, but two months ago, the progress of Qu Yue's cultivation, which had advanced by leaps and bounds, suddenly came to an abrupt halt, and there was no progress at all, he had consulted He Zhan, but He Zhan also had no way.

From He Zhan, I learned that the sixth to seventh layers of condensation qi are a big level, and they can be regarded as the first hurdle on the road to cultivation. This hurdle is something that many people don't want to face and have to face.

Only by being able to cross this hurdle can it be regarded as embarking on the path of cultivation. However, there is not one in ten cultivators who can cross this hurdle, so those who are stuck under this hurdle can only be an ordinary "mortal" with peace of mind.

Since ancient times, I don't know how many people have been stuck in this layer and have lost hope of building a foundation. Even some of the great sects, the children of the famous families of the big families, once they are stuck in this layer, there is no way to do it, because outsiders cannot help at this level, so they can only cross it by themselves.

Take Ruby, for example!

It took nearly two years from the sixth layer to the seventh layer of condensation, if it wasn't for the recent period of time to follow the bald bird and comprehend, I'm afraid I would have to stay in the sixth layer of condensation for a while, once I was unlucky, I wouldn't even be able to advance an inch in my life.

Qu Yue is stuck on this hurdle now, and he intends to find an opportunity for the bald bird to get a breakthrough.

Quickly walked to the back mountain, and found no trace of the bald bird and red jade, and after searching for nothing, he found a clean rock and sat on it to enter the cultivation state. Although this is not of much use, the path of cultivation is based on chance, and who can say that Qu Yue will not break through in a flash of inspiration.

Qu Yue slowly entered the cultivation state, and at the moment of entering the cultivation state, Qu Yue suddenly found that there was a trace of undetectable cold current coming from the dantian in his abdomen, and he returned to the dantian after quickly wandering through the veins of his whole body.

This cold snap appeared quickly enough, and disappeared very quickly. Qu Yue's mind moved, and he concentrated all his thoughts on the dantian and quietly perceived.

Qu Yue suddenly opened his eyes with excitement on his face, because he finally understood the important reason why Xiu Wei was stuck below the seventh layer.

After condensing the qi for seven layers, it is time to prepare for the foundation building. Only after reaching the foundation can the external aura enter the body and open up the dantian world. However, before that, that is, during the condensation period, you must learn how to guide the spiritual power from the outside world into your body. The first six layers of Qi Condensation mainly focus on the physical fitness of cultivation and the endurance of the Spiritual Qi Infused Body! After the seventh layer, they begin to pay attention to the cognition of the dantian.

At this time, a special qi will be produced in the dantian, of course, this qi is not aura, but a kind of true qi in the body. This kind of true qi is divided into acquired and innate, and only when the cultivation reaches the seventh layer of condensation qi will a trace of acquired true qi be produced in the body. With the growth of cultivation, this trace of innocence will gradually increase. When the cultivation reaches the foundation, the acquired true qi will produce qualitative changes with the quantitative change, turning into a trace of innate true qi, and only the innate true qi can have a guiding effect with the aura in nature, thus pulling them into the body to open up the dantian world.

The cold current that Qu Yue perceives is the acquired true qi, only by truly mastering the control of this trace of acquired true qi can he break through the shackles of the sixth layer and reach the acquired realm of the seventh layer, understanding this, Qu Yue believes that the seventh layer of condensation qi is just around the corner.

Quickly closed his eyes, refocused on feeling this trace of innocence, and guided and controlled with spiritual power, although he could not achieve immediate success, Qu Yue did not give up, but tirelessly repeated and repeated!

After two hours of unremitting efforts, Qu Yue's cultivation finally succeeded in reaching the seventh layer!

Slowly opening his eyes, Qu Yue at this time did not have the surprise on his face after the breakthrough, but frowned.

Qu Yue found that since he controlled this trace of post-innocence qi, he could very clearly perceive that there was a murderous aura hidden in this trace of post-innocence qi, although it was not obvious, but Qu Yue was still surprised.

He was very familiar with this murderous aura, after encountering the bald bird for the first time half a year ago, when Hongyu was in a coma, when his mind was lost, the earth-shattering murderous aura emanating from the bottom of his heart was exactly the same as the murderous aura in the true qi.
