When Xuan Yunxing heard Tang Yu's words, he blinked and muttered in a low voice: "Master, even if we have not destroyed many headless corpses, from the current situation, if we want to solve the headless corpses in the Black Evil Land, even if we can only destroy one hundred headless corpses according to one sound fire thunder, the number of sound fire thunder required is less than 10 billion!"

"Isn't ten billion yuan still a lot?" Hearing Xuan Yunxing's tone, Tang Yu gritted his teeth in anger.

Xuan Yunxing touched his neck and saw Tang Yu's angry expression, he was frightened and shrunk his head, but he couldn't help but say, "In just a few days, the master has refined nearly 200 million sound fire thunders, 10 billion, which shouldn't be much!"

"Yes! Not many! There are only 10 billion. Not to mention whether I have so many spiritual sound stones, I just want to refine 10 billion sound fire thunders. It will take about two months to take." Tang Yu said in a sarcastic manner.

"Ah! Does it take so much time?" At first glance, it doesn't seem to take a lot of time, but after careful calculation, Xuan Yunxing realized that it seems that there is indeed more time.

More importantly, he heard Tang Yu say that the important material for refining sound and fire thunder is not enough.

Xuan Yunxing had never seen such a thing before. He guessed that it must have been obtained by Tang Yu from another place, so he grinned, smirked and stopped talking.

There was Tang Yu nearby, because Tang Yu was there, so there were not many magic-modified cannons left. The number of them was added up, and it might be only about a thousand.

After all, the number of channels that broke out this time reached hundreds. Even if 10,000 magic-modified cannons were reserved for one channel, after being consumed by Mr. Xingchen, the number of magic-modified cannons was still too far away from the number of millions.

Moreover, according to past circumstances, ten thousand magic-modified cannons near one passage are not enough.

Only millions of demon-modified cannons can allow the practitioners of Gusha Mountain to easily kill these beasts without missing a headless corpse.

But now, this cannot be achieved, so this battle is still relatively difficult now.

Fortunately, the effect of sound and fire thunder is better than Tang Yu imagined, and he also distributed more sound and fire thunder.

On average, nearly hundreds of thousands of sound and fire thunders can be arranged near each passage. As long as the practitioners of Gusha Mountain are not fools, they can basically withstand this wave of attacks with these sound and fire thunders.

Tang Yu could only pray that the next wave of full attack could last longer, even if it was only ten days, Tang Yu was satisfied.

Half a day later, no headless corpses appeared in the passage where Tang Yu was.

Because it has been confirmed that the outbreak of this incident is the outbreak of a total war, Tang Yu felt that it was no longer necessary and continued to stay in the Black Evil clone to patrol something.

Anyway, there are enemies everywhere, so it’s better to stay by your side and help yourself more. Doesn’t it mean that you have a lot to help Gusha Mountain?

Tang Yu shamelessly turned the idea of ​​facilitating himself into a thought of facilitating everyone.

However, at this time, Tang Yu had a very high status among the entire ancient temple mountain practitioners. Even if he expressed his ideas, no one would doubt anything. Instead, he would really feel that the purpose of Tang Yu doing this was to help big and small.

So, the Chaos Eagle clone changed from patrolling the entire Black Evil Land to an area near the passage where Tang Yu was located.

After there was no headless corpse and appeared from the passage of the Black Evil Land, Tang Yu specifically asked about the Chaos Eagle clone, and he also received news that there was indeed no headless corpse near this passage.

Tang Yu began to calculate the consumption this time with joy.

Because there are only a thousand magic-modified cannons, the main attack method near the passage where Tang Yu is located becomes Sound Fire Thunder.

The power of the sound fire thunder did not disappoint Tang Yu. Although it did not reach the level of killing a thousand headless corpses at one time at the beginning, after all, the first wave of attacks was not just one sound fire thunder explosion, but dozens of sound fire thunder explosions, killing the thousands of headless thunders.

Moreover, if you destroy the corpses of dozens of monsters first, it will definitely offset the power of some sound and fire thunder.

It is precisely because of this that on average, it has reached the level of a sound fire thunder that can destroy nearly a hundred headless corpses.

Coupled with some consumption in other messy aspects, the total number of sound and fire thunders consumed reached 100,000.

Someone said that if one hundred thousand sound fire thunders were calculated based on the average, it would mean that the headless corpses appeared in this passage reached tens of millions?

Of course not so many.

The main reason is that there are more wasteful sound and fire thunders. After all, everyone’s tacit understanding is not particularly good. It often appears. There is no headless corpse and appears from the passage. As a result, there is another person who throws out a lot of sound and fire thunders because he is too nervous.

These sound and fire thunders were consumed in vain.

These sound and fire thunders that were consumed were not counted by Tang Yu. Therefore, the number of sound and fire thunders consumed was finally counted to obtain 100,000.

Otherwise, 20,000 sound fire thunders could easily deal with this wave of headless corpses.

According to the attack efficiency here, even if there are 1,000 channels appearing this time, the 100 million sound fire thunder refined by Tang Yu is enough to eliminate all these headless corpses.

But if calculated based on one thousand channels, it means that the number of headless corpses that appeared this time reached billions.

But obviously, this number is very inaccurate.

And there will be another situation where the number of spiritual sound stones that have been refined by Tang Yu on his body will be extremely short of.

It can even be said that it is really not enough.

However, if we can survive this wave, even if we consume all the ninety million sound fire thunders distributed, Tang Yu can relax a little. Tang Yu is only looking forward to not having large-scale casualties.

The cultivators in Gusha Mountain have only a few hundred million. If there are a slight loss of larger casualties, Tang Yu's previous efforts will fail.

After all, there are no people and I still guard the ancient temple mountain. What's the point?

Shortly after the battle ended on Tang Yu's side, the jade slip that Mr. Xingchen gave to Tang Yu also sounded a burst of urgent prompt sounds.

Tang Yu suddenly became a little nervous. He didn't know whether this message transmission was good or bad news.

"drop!"

As soon as the sound transmission slip was connected, Mr. Xingchen's heartfelt laughter came from the opposite side. When he heard this laughter, Tang Yu's nervousness disappeared in an instant. Tang Yu knew that if it weren't for good news, Mr. Xingchen would never be so happy.

"Old man, is there a great victory coming?" Tang Yu asked with a smile.

"Boy Tang, do you know how great our victory is?" Old Master Xingchen looked so happy that he actually kept Tang Yu in hiding.

"First of all, we will wipe out this wave of enemies!" Tang Yu said with a smile without giving Mr. Xingchen the opportunity to cheer up his appetite.

"Yes, we..." Old Master Xingchen wanted to speak out when he heard Tang Yu's tone was wrong, but Tang Yu deliberately did not give him a chance and spoke again: "Secondly, there should not be many casualties here, and the number of casualties should be less than one hundred!"
