Condensing Yuan Dan is to gather a true Yuan in the dantian and condense it into a pill, which is Yuan Dan.

However, the condensation of the Yuan Dan is not so simple, it requires a deep True Yuan, a huge divine sense, and a strong physical body as the foundation, and with the will of the Qi refining martial cultivator as the core, it is possible to condense the Yuan Dan belonging to the martial monk.

Xia Fan would never worry about the strength of his physical body, and his divine sense, which had been tempered for two years by refining the Divine Technique, had also reached the realm of Dacheng, which was enough to meet the requirements of condensing the Yuan Dan.

However, the absolute inadequacy of the true yuan made Xia Fan's condensation of Yuan Dan a joke, and Xia Fan had not yet understood his own will, could not understand his most basic path, and could not condense the core of Yuan Dan, and this was also the reason why Dean Shen Danfeng had no confidence in whether Xia Fan could achieve Yuan Dan.

Therefore, Xia Fan proposed to walk alone through the Southern Wilderness Continent, just to find a solution and opportunity to solve his own shortcomings.

Therefore, Xia Fan was in a state of battle from the moment he walked out of the city of Annan, the king of Nanyue, and along the way to the Great Chu State in the north, Xia Fan killed a large number of fierce beasts, and an invisible fierce aura emanated from Xia Fan's body and permeated Xia Fan's body.

This is not the external evil qi absorbed by Xia Fan, but the evil qi generated by Xia Fan himself, composed of powerful killing intent.

Under the threat of this evil aura, wherever Xia Fan passed, some middle and low-level fierce beasts did not rush to fight with them at all, and retreated one after another, only the high-level fierce beast was attracted by the evil qi on Xia Fan's body, and instead slaughtered Xia Fan.

But in the face of Xia Fan's iron fist, all the high-level fierce beasts were shattered to pieces, and there were no corpses to die.

As he continued to move forward, Xia Fan waded through mountains and rivers, getting closer and closer to the border between the two countries, and the border was high and dense, which was the place where fierce beasts were most rampant, and a large number of high-level fierce beasts gathered here.

At this time, on the periphery of this mountain forest, some martial monks could already be seen forming teams to fight with the fierce beasts, although the peripheral fierce beasts were only some low- and middle-level fierce beasts, but the intensity of the battle was beyond Xia Fan's expectations.

Obviously, in the border between these two countries, whether it is a human or a fierce beast, their combat effectiveness is much stronger than that of the martial monks around the Yandang Mountain Range.

On this border, the Nanyue Kingdom built a huge war fortress here to defend against the invasion of fierce beasts, and of course, to defend against the invasion of the Great Chu State, and these warrior monks came from this fortress.

Although these warrior monks only possess low- and mid-level combat power, the fierce battles between fierce beasts and humans for many years have greatly improved the combat effectiveness of these warrior monks.

The battle was very fierce, from time to time there were warrior monks who were injured and retreated to bandage their wounds, and then rushed back to the battlefield, and even some warrior monks died on the spot because they couldn't dodge the fierce attacks of the fierce beasts, but Lin Qing didn't see a person afraid of death and withdrew from the battle.

Looking at these martial arts monks full of fighting spirit, Xia Fan's heart flashed with inspiration, and he seemed to have an understanding, but inspiration came and went quickly, but Xia Fan had not yet realized it.

However, Xia Fan knew that here, there was an opportunity for him, and Xia Fan, who had decided to go directly over the mountain, walked into the fortress of war.

The giant war fortress was built on the gap of a large mountain, this big mountain is called the Nanling Mountain Range, which is as high as 10,000 meters, vertical and horizontal from east to west, stretching for thousands of miles, separating the entire Nanyue State from the Great Chu State, and becoming a natural national border between the two countries.

Because the mountain is 10,000 meters high, and the north and south sides of the mountain are cliffs up to 1,000 meters high, even high-level beasts cannot jump off the cliffs, and all the beasts can only enter and exit from the only few gaps in the mountain that are as wide as a kilometer.

The South Vietnamese State built several huge war fortresses in these gaps to defend against the attacks of fierce beasts.

When Xia Fan walked into this war fortress, he found that the war fortress was indeed very large, and it was not under Yansang City.

However, in addition to resisting the attacks of fierce beasts, Yansang City also has the role of the county capital, and is the political, cultural, and economic center of a county, while the fortress in front of Xia Fan is a pure war fortress, which only exists for war, and the two are not the same.

After entering the fortress, Xia Fan immediately felt a huge aura filling the entire fortress, this aura Xia Fan was very familiar with, it was the purest iron-blooded evil qi.

In the midst of this iron-blooded aura, Xia Fan's blood was boiling.

In the two years in the secret realm of South Vietnam, although Xia Fan was absorbing evil qi cultivation all the time, and that evil qi also contained a huge amount of iron-blooded ferocity, the evil qi in the secret territory of South Vietnam was obviously different from the iron-blooded evil qi in this war fortress.

The gap between the two is like the air in Xia Fan's previous life in the city full of car exhaust and chemical pollution and the early morning air in the countryside and mountains, which are two completely different feelings.

The war fortress is divided into two defenses, north and south, but in fact, the army in the fortress only needs to defend against attacks from the north, which is from the fierce beast attack in the South Ridge Mountain.

Compared to the huge number of fierce beasts in the north and extremely high combat power, the fierce beasts in the south of the fortress are really not worth mentioning, and the middle and low-level martial monks can limit their activities.

And to the north of the war fortress, the entire war fortress has to withstand the crazy attacks of countless fierce beasts every ten days and half a month, and its attack power is so strong that it can be called a small beast tide.

This time, Xia Fan came to the war fortress, just in time for an attack by the fierce beasts, and the fierce beasts that were all over the gap in the mountain were cold in Xia Fan's heart even when he saw it, after all, this was the first time Xia Fan faced such an attack of such intensity.

The wall of the war fortress is extremely high, ten zhang nearly thirty meters high, such a height, even the highest fierce beasts can not climb the city wall, plus the city wall is like a rain of arrows, for a while, the attack of the fierce beasts is temporarily blocked under the city.

However, these fierce beasts seemed to have wisdom, and the tall and thick-skinned beasts came to the foot of the city wall spontaneously, fearless of death, and did not care about the bows and arrows on the city wall, and superimposed on each other, like a human ladder, to build a beast ladder.

After the beast ladder was built, countless agile beasts ran up the city wall along the beast ladder and slaughtered the Terran warriors guarding the city wall.

The warrior in the fortress of war had a calm face, drew his weapon, and strictly guarded his position, and when the fierce beast pounced, he fiercely slashed out the sword in his hand, blood splashed, and the fierce beast was killed by a sword.

However, in the face of the beast tide composed of countless fierce beasts, the killing of a fierce beast did not mean anything, and countless fierce beasts pounced on the city again.

In the face of the attack and killing of countless fierce beasts, no one could deal with it safely, and the thousands of soldiers on the front line were traumatized in an instant, and even died in Huangquan, but the soldiers in the rear immediately pounced without the slightest fear.

At this time, whether it was a soldier in the regular army or a Qi refining martial cultivator, they were all high-spirited and war-spirited, just because they wanted to protect everything behind them, where there were their parents, wives and children, and their friends and compatriots.

What a similar scene this is! Xia Fan's eyes flashed with the war in Dingwu City a few years ago, the same full of fighting spirit, the same fearless of life and death, all of which were just for protection, guarding everything behind him.

At this moment, Xia Fan's mind was turbulent, he understood, he finally understood, and understood what the core of his will to condense Yuan Dan was.

In fact, Xia Fan already has the core of this will, and it has always existed in Xia Fan, it is-

- "Fight!"
