The last time Qin Mu came to the East China Sea Theater for training, the purpose was to let the Seven Emotions and Six Desires Great Heart Demon System lock more targets, so at that time, Qin Mu mainly stimulated and provoked the Kraken, and there were not many Krakens killed, but this time the purpose was different.

This time, Qin Mu wanted to fill the heart source, so that the Seven Emotions and Six Desires Great Heart Demon System could be upgraded, so Qin Mu wanted to kill until the kraken collapsed.

Under Qin Mu's control, the sword light swimming dragon kept wandering around, killing one kraken after another, because the people who hit the coast were all ordinary krakens, and the most powerful ones were equivalent to star warriors, so naturally none of the krakens were Qin Mu's opponents.

The coastline of the East China Sea Theater is very long, Qin Mu kills from south to north, and from north to south, and the sword light swimming dragon is like a real dragon under Qin Mu's control, devouring and strangling countless krakens.

In this process, countless krakens roared angrily and were locked by the Seven Emotions and Six Desires Great Heart Demon System, but then they were all killed by Qin Mu, and when the Kraken was killed, the emotional time collected by the Seven Emotions and Six Desires Great Heart Demon System naturally dissipated.

But Qin Mu didn't care about these at all, if he wanted to do a good job, he must first sharpen his tools, once the Seven Emotions and Six Desires Great Heart Demon System was successfully upgraded, Qin Mu basically didn't have to work hard to collect cultivation time.

At that time, as long as the Seven Emotions and Six Desires Great Heart Demon System locks on ten thousand targets, then whether Qin Mu provokes it or not, the seven emotions and six desires generated by these ten thousand goals will provide Qin Mu with cultivation time.

Qin Mu didn't know how many krakens he had killed, anyway, he killed from morning to night, but the next day was repeated, and half a month was spent like this.

"It's not very good. Sitting on top of the Great Wall of Steel, Qin Mu muttered in his heart while gnawing on a crab leg.

After killing the Kraken for half a month, Qin Mu's progress in various boxing techniques and fist intent is obvious, but the accumulation of heart source is not much, except for the two that Wei Zixuan selflessly dedicated before, there are only three more in total.

With such efficiency, if you want to fill up the heart source, you don't know what happened in the Year of the Monkey, but what went wrong?

"There aren't many krakens today, and it's not enough for Brother Qin Mu to kill!" Just as Qin Mu was thinking about this, one of the guards said with a smile.

Hearing this, another guard responded with a smile, "Although these ordinary krakens are stupid, they also know that they are afraid, they have been killed so much by Brother Qin Mu, how dare they come!"

However, when the words of these two guards fell, Qin Mu's eyes suddenly lit up, and he secretly scolded himself for being confused, why didn't he think of this!

As the guard in the back said, ordinary Krakens are very stupid, and they are all dead-eyed, except for anger and fear, no matter how you provoke the excitement, ordinary Kraken's emotions are not easy to collapse.

"Looks like you're looking for a stronger kraken. Qin Mu said in his heart.

Qin Mu also remembered at this time, the three heart sources collected later were obtained by him chasing and killing a kraken equivalent to the strength of a star martial artist, which made Qin Mu immediately know what to do.

After glancing at the Seven Emotions and Six Desires Great Heart Demon System, the cultivation time accumulated now was enough to support Qin Mu to use the breath simulation to stay at the bottom of the sea for three days, and if he didn't use the breath simulation, he could let Qin Mu stay at the bottom of the sea for seven days, which made Qin Mu feel at ease.

The next moment, the starlight rose under Qin Mu's feet, rushed into the sky, and went straight to the East China Sea in front of him, and under the stunned eyes of the guards on the Great Wall of Steel, Qin Mu plunged into the East China Sea.

"Brother Qin Mu, are you going to take a bath again?" said with a joke.

The other guards all laughed when they heard this, because Qin Mu had already done the same thing last time, so these guards were not worried about Qin Mu's safety.

At the same time, after Qin Mu plunged into the East China Sea, he did not turn on the breath simulation, but swam freely in the East China Sea in a big way, he was to collect the East China Sea where the heart source entered, if he simulated the breath and let other krakens regard him as the same kind, how could he still collect it?

There were all ordinary krakens in the near sea, and when they saw Qin Mu actually chasing and killing them, they all roared angrily, but none of them dared to kill Qin Mu, but they all hid far away.

After being killed for half a month in a row, these ordinary krakens were really scared of being killed by Qin Mu.

Qin Mu didn't have time to deal with these ordinary krakens, and he swam in the direction of the deep sea with the starlight, and the target was the place where he had obtained the inferior dragon fruit last time.

Along the way, he encountered a few krakens with the strength of star martial artists, and was chased and killed by Qin Mu for a while, and finally let Qin Mu harvest a few heart sources, Qin Mu was immediately overjoyed, he had already entered the sea if he knew this.

"Huh, this is it, why is that strange tree gone?"

When Qin Mu arrived at the place where he got the inferior dragon fruit last time, he found that the tree was gone, and his heart was full of doubts, and his heart was full of disappointment for a while.

The last time Qin Mu entered the sea, he had just become a star martial artist, and now he had been knighted, so Qin Mu felt that he could get the dragon fruit last time, and he would definitely be able to do it this time, but he didn't expect the fruit tree to be gone!

Without fruit trees, naturally there is no way to get dragon fruit, and Qin Mu has no choice but to go somewhere else.

But just as Qin Mu was about to leave, suddenly a dangerous aura gushed out from the place where the fruit tree was, and the next moment, one by one, black light shot out and stabbed at Qin Mu.

It was a two-foot-long, steel-like thing, seeing this, Qin Mu's body shook, and he dodged with the starlight, and then looked forward, but saw a huge thorn dolphin two or three meters long swimming out, full of qi and blood, and actually had the strength of a viscount warrior.

However, this thorn dolphin should have just been promoted, and the power of qi and blood is only the minimum standard of a viscount martial artist.

"Bold human, you actually dare to trespass on the territory of the Dragon King, you deserve death!" At this time, a wave of spiritual power fluctuated into Qin Mu's mind.

Ordinary Krakens have weak mental power, but the Kraken with the strength of a knighted warrior can communicate with humans through spiritual power, and the King-level Kraken is naturally able to speak.

"Dry, numb, not mellow at all, coil it!" As the spiny dolphin passed on the spiritual power, Qin Mu also urged the spiritual power to pass on the past to the thorn dolphin.

Although the thorn dolphin that appeared had the strength of a viscount warrior, Qin Mu controlled his fist intent with the emperor's intent, and the power that burst out was able to withstand the attack and killing of the duke warrior, and now it was just a thorn dolphin with the strength of a viscount warrior, of course Qin Mu could control it!

Of course, the thorn dolphin was covered with spikes, but he couldn't use his hand, Qin Mu immediately urged the Wuyue sword intent, and the sword light swimming dragon appeared, enveloping the thorn dolphin.
