Not to mention the undercurrent surging on the side of Heaven Dou City, in the valley outside Martial Spirit City, Tian Hao frowned, obviously encountering a problem.

"It's not that simple." Signaling Ah Zi to stop the thunder guidance here, Tian Hao was a little depressed.

Thunder Quenching Soul can indeed increase the fusion degree of soul power, and drive to increase the fusion degree of the two Martial Soul Grass Swords.

The progress was still very smooth before, and the degree of integration was steadily improving, almost one percentage point in a day, but when it reached 99 percent, it encountered a bottleneck again, and there was no progress for four days, and there was no sign of a breakthrough at all.

Even if the thunder containing the power of thunder tribulation is triggered, it will only completely annihilate the soul power, but it will not be able to promote the qualitative change of the soul power and break through the last bottleneck.

"Don't be discouraged, you are still young, and you will have time to cultivate in the future." Golden Crocodile Douluo, who was resting outside the Thunder Pool, saw that Tian Hao's expression was not good, and comforted him kindly.

He is the oldest in the Martial Spirit Hall at this stage, and he has been cultivating for more than a hundred years, especially after being stuck on the threshold of the ninety-eighth level for decades, he knows very well that he must have enough patience at this stage to endure loneliness.

"I know." Nodding in understanding, he immediately took a deep breath and looked at the purple thunder pool.

"My soul power is too weak, if I can improve it a little more and carry a trace of thunder tribulation power, I may be able to break through that level." He was sure that as long as his soul power could withstand the thunder containing the power of the Thunder Tribulation, he would definitely be able to break through the final level and achieve 100% perfect fusion.

Of course, another reason why it is difficult to break through is that the attributes of the two grass swords are different, and the difficulty of fusion is higher.

This is fundamentally different from Senior Brother Chenxin's fusion of two seven-killing swords, although the Shura Seven Killing Sword is integrated into the Shura seed, but the essence is still the seven-killing sword, and it is still the martial soul of Chenxin's father, and it has a very high degree of compatibility with Chenxin, and it is not surprising that it can quickly reach 100% fusion.

And Tian Hao's two grass swords don't have that benefit, in addition to the reason for soul power. In the end, his soul power is a little worse, if the soul power of the two grass swords reaches level forty or even fifty, it will definitely be able to carry the thunder that contains the power of thunder.

But he still has to stay at level 30 to try to condense the soul core, which is contradictory.

"Second grandfather, don't you have an eyebrow for the study of qi and blood?" As soon as the voice changed, Tian Hao asked about the progress of research on qi and blood.

He didn't care about it anymore after he first proposed Qi and Blood, thinking that it would produce results soon, but it didn't succeed until now.

"The problem lies in the power of the bloodline and the martial soul, I plan to find a way to completely integrate the martial soul into the body on the basis of the true body of the martial soul, so as to enhance the power of the bloodline and qi and blood, and stimulate the qi and blood to be active." Speaking of this, Golden Crocodile Douluo's face became serious, this has always been his main job.

He is the person with the strongest physical fitness in the Martial Spirit Hall at present, and the qi and blood in his body are also the most vigorous, so he can only study it.

However, although his qi and blood were vigorous, it was difficult to stimulate it and activate it, so that it could be circulated and cultivated like soul power.

There are many difficulties to overcome in this regard, some of which have been overcome so far, but there are still a lot left, and we have to take our time.

Tian Hao didn't have any good ideas about this aspect, the cultivation of qi and blood started from the Ontology Sect, although his first martial soul was regarded as an ontological martial soul, but it had nothing to do with the body's qi and blood.

In this regard, Golden Crocodile Douluo and others have to ponder and study on their own, but under the command, with the cultivation of Golden Crocodile Douluo and others, they will definitely be able to produce results, it is nothing more than a matter of time.

qqxsnew hopes it will be faster. After communicating with Golden Crocodile Douluo for a while, and finally leaving a large amount of life divine power, Tian Hao walked out of the valley, nodded to the angel team that had been waiting outside, and sent him back to the Battle Spirit Sect.

When he returned to the Battle Soul Sect this time, in addition to the fact that he needed to set off from the Battle Soul Sect and go to Wuhun City to participate in the finals openly, there was also a point that Senior Brother Chenxin arranged a special trial for him here.

Sensing Tian Hao's outburst of sword intent, the dust heart of the War Soul Sect who was in retreat and penance arrived as soon as possible, and brought it to the ancestral tomb of their War Spirit Sect.

"You're just going to be buried in the valley?" Coming to a valley, Tian Hao looked at the word sword mound carved on the cliff wall at the mouth of the valley, and didn't quite understand the burial method of the Battle Spirit Sect.

In his opinion, the burial of the ancestors should be hidden in the mountain, like the tomb of the angel's ancestors. After all, the corpse of a strong person is also a valuable asset, not to mention that the Seven Killing Sword Pulse can basically be cultivated to the Super Douluo level, and the value of such a strong person's body can be imagined.

But now it is buried in a valley, and there is no trap to protect it.

Aren't you afraid of popping up some underground professions like a golden captain?

"The sword mound is the sleeping place of our ancestors, and it is also the place where our clan has experienced, and there are seven killing sword intent left by the ancestors of the past generations, I am waiting for you at the end, don't have any hostility, otherwise it will be very dangerous." Leaving a word, Dustheart stepped into the depths of the valley.

"No wonder." With a sudden look on his face, Tian Hao understood that the danger of the sword mound must be the Seven Killing Sword Intent, which was also the uniqueness of the Battle Spirit Sect.

When a person dies like a lamp going out, his body will decay, his soul power will dissipate, and his martial soul and soul will disintegrate, but his sword intent will last forever.

I don't know how many bigwigs of the Battle Spirit Sect have been buried inside, and the accumulated Seven Kills Sword Intent Ghost knows what extent.

"I hope there will be a big harvest." Tian Hao stepped forward with anticipation and walked into the sword mound. As soon as he walked in, he seemed to have touched some kind of existence, and a fierce seven-killing sword intent pressed him, making him seem to see a huge seven-killing sword stabbing down, trying to nail him to the ground.

"Sword Intent!" The purple gold grass sword was manifested, and the sword intent surged, resisting the attacking seven-killing sword intent. The swordsman's path would rather bend than bend, and there is no choice to retreat.

Qiang moved forward under the suppression of the Seven Killings Sword Intent, and soon came to a tomb, where an ancestor of the Battle Spirit Sect was buried.

He stopped and saluted to the tomb, and then continued to walk forward, and a new Seven Killing Sword Intent attacked, which was even more powerful than the one just now, and the pressure caused was also stronger.

Still carrying forward with sword intent, with a vast spiritual power as a supplement, Tian Hao's sword intent was always strong, and he walked half of the sword mound in one go.

But when he reached the bottom half, his complexion changed, and a greater oppressive force suppressed him, almost pressing him to his knees.

"Seven Kills Realm!" Holding on strongly, Tian Hao had to sigh at the strength of the Battle Soul Sect, the seven killing sword intent left behind after death in the front was already amazing, and even the seven killing realm could be left here in the second half.

No wonder the Battle Spirit Sect will bury the ancestors directly here, with this posture, even if the Title Douluo comes, he has to kneel.

At the same time, I am afraid that this is also the last place of refuge for the War Spirit Sect, if you really want to encounter a strong enemy, you can hide here, and attract the Seven Killing Sword Intent and the Seven Killing Realm left by the ancestors of the past dynasties to fight against the enemy.

It is also that he has no malicious intent, otherwise once those Seven Killing Sword Intents are fully triggered, the spiritual consciousness and even the spiritual sea will have to be shredded, and he will become a vegetative person.

This is the terrifying sword intent, it is completely a spiritual attack, and it is difficult to guard against.
