At the bottom of the identification tower, only two rooms away from the Kesu Stone Slab, there was a cultivation secret room eight meters deep, this secret room existed as early as the establishment of the Los Branch, and it was a cultivation place specially prepared by Duan Lie for himself.

The cultivation secret room covers an area of five hundred square meters, and the surrounding walls, ground, and ceiling are all made of the strongest chromium steel ore, and the anti-destruction effect is quite good, with Duan Lie's strength close to the Eight Battle Spirits, he can basically withstand the pressure of more than 100,000 punches, and this effect is enough for him to dismantle casually in the cultivation secret room.

Of course, this is also the superior condition that Duan Lie has long imagined for himself to improve his strength, a 500-square-meter secret room made of chromium steel ore, even if two war madmen fight against each other, there is no problem at all.

There are only a few pillars supporting the secret room in the empty cultivation room, all of which are made of chromium steel ore, and there is only a small table in the center, where all kinds of potions are placed.

For example, dragon's blood elixir, fanatic potion, war spirit potion, long-lasting potion, as well as anti-stress elixirs, energy awakening potions, and powerful endurance potions for mental power...... And so on up to fifteen kinds......

Without exception, these elixirs are all mixed with dragon blood, an indispensable and powerful material, which is also placed in the cultivation secret room, and if it is taken out, it will definitely make many people crazy.

In addition to the elixir, Duan Lie also prepared a large number of Void Stones, after all, pressure training was the most effective way, and the main role of the Void Stones could change the spatial sequence, constituting gravity, tearing, and suppression...... and so on, creating a relatively harsh cultivation environment, mainly to stimulate the extreme potential of the human body.

After making so many preparations, if he couldn't break through to the Battle Maniac level within a year, Duan Lie felt that he would have no face.

Then, he made a full plan for his training.

The first step is to meditate first, and maximize the cultivation of one's fighting spirit from the level of the war spirit to the realm of war madness, so that the fighting spirit can achieve a fundamental change. Of course, this is a rather long process, and it is not something that can be done with a few bottles of potion, in order to raise the level of Dou Qi, first of all, the body must first have the ability and toughness to withstand the corresponding level of Dou Qi, so the key is the second step.

The second step is physical fitness. This is the key to anti-pressure training, Duan Lie used the Void Stone to put a fourfold spatial rhythm space shackle for himself, and then set up a gravity force field under the inscription trap of the outer ring structure, so that he does not need to use gravity to suppress and waste spiritual power to create a cultivation environment, and the combination and arrangement of this gravity force field can be changed at will, and the maximum multiple can reach forty times, which is similar to Duan Lie's current Dou Qi force field level.

The limit of forty times the gravity is basically sufficient.

The third step is mental anti-stress training, in this regard, Duan Lie plans to use the spiritual awakening medicine to assist him for a long time, and improve his mental state by a few percentage points to a certain extent, which is equivalent to the secret medicine of hyperactivity, and always keep the most sober mind. It's just that this medicine has a very serious negative effect, and once it is not used properly, it will put the body in a state of extreme overdraft, and it needs to be used carefully.

After the plan was ready, Duan Lie made a clear arrangement and assignment of his cultivation tasks.

The first step of careful arrangement, Duan Lie planned to improve his strength to the eighth-level battle spirit first, after all, his current level happened to be on the edge of the eighth-level war spirit, once he reached the level of the eighth-level war spirit, he could deeply contact the Vulcan Sword Technique, and then use the Vulcan Sword Technique to gradually improve his combat awareness and combat intensity. He didn't have any other combat skills to practice now.

And the Vulcan Sword Technique is precisely the kind of powerful method that takes a lot of time to pile up, Lin Xiao only left him one sentence before leaving: If you want to practice the Vulcan Sword Technique to the point where you are proficient, there is only one word, that is: practice.

The initial plan was properly arranged, Duan Lie opened a bottle of long-lasting elixir and poured it directly, and when the mild long-lasting elixir was entered, he felt a clear warm current flowing through his body.

This is a preliminary preparation, the significance of the existence of the long-lasting elixir is that it can raise the physical fitness to an extremely terrifying strength in a short period of time, and with the endurance elixir, it can also perform combat skills for a long time, which is generally deployed for cultivation.

The ultimate goal of drinking the long-lasting medicine first is to improve the physical fitness and accept the baptism of anti-fanatic medicine.

The three-hour timeliness of the fanatical elixir can multiply the dou qi, greatly improve the activity of the dou qi, and stimulate the body to receive more quenched new dou qi.

The effect of the combination of the two elixirs is to accelerate the meditation......

A faint halo emerged from the surface of his body after taking the two potions, Duan Lie took off all the clothes on his upper body, sat cross-legged on the ground bare-chested, and began a long and endless meditation with his eyes closed.

With his acquaintance with Lin Xiao, Duan Lie suddenly felt that the Empty Empty Qi Cultivation Technique was not from the Western Continent, although the Wuji God of War respected it back then, but he didn't know the origin of the Empty Empty Qi Cultivation Technique at all, and the reason why Duan Lie knew it was because there were many similarities between this mental method and the Fire God Sword Technique, including the characteristics of the luck and so on, as well as the description of the know-how, which was fundamentally in the tone of the Eastern Warring States.

At this point, Duan Lie was sure that the Empty Qi Cultivation Technique was definitely a product of the Eastern Warring States.

Lin Xiao also said that his meditation technique was very suitable for the characteristics of the Fire God Sword Technique......

Such a good technique and combat skills have a degree of matching and fit, and being able to get Lin Xiao's praise, Duan Lie is even more sure that the origin of the Empty Qi Cultivation Technique is extraordinary.

When the Dou Qi traveled according to the route in the body, he clearly felt that the flow rate of his Dou Qi had doubled, the body was a big cycle, the Dou Qi flowed out from the Battle Spirit, and after completing a cycle in the body and then returning to the War Soul was regarded as a circuit, and this time, with the Fanatic Elixir and the Long-lasting Elixir, his physical fitness was not only improved accordingly, but the flow rate of the Dou Qi and the strength of the Dou Qi also increased significantly.

The seven-system fighting qi was like a seven-colored rainbow flowing out of the meridians, and the pain caused by the stimulation of the meridians was relatively greater, and soon, Duan Lie's face was covered with beads of painful sweat, but with the help of the long-lasting medicine, his pain was invisibly doubled, and he was able to persevere.

Judging from my physical condition, I am afraid that this meditation will take at least three days......

Meditation that does not wake up for up to three days is called deep meditation.
