After fully laying the formation, Tang Yu could finally breathe a sigh of relief. Looking at the group of mice outside the formation, like fools, rushing towards the formation frantically, but in the end they could only die under the attack of the formation. Tang Yu was so happy.

Thinking of his embarrassing look just now, Tang Yu's smile on his face became restrained again. He looked outside the formation and saw that the rat tide still couldn't see it. He thought in his mind that the attack of the formation seemed to be a little weak, once every thirty seconds. Although he could destroy rats within a radius of 500 meters every time, it seemed like a drop in the bucket to the rat tide, and it was not worth being happy at all!

It seems that the attack ability of the formation needs to be improved further.

But the problem is that the formation in front of you has almost reached a perfect level. If you want to improve your attack ability, you need to carefully modify some things slightly. If it is modified well, the attack and defense capabilities of the formation can be greatly improved. However, if there is a slight mistake, the entire formation will probably be destroyed directly, and even Tang Yu will suffer very serious damage.

"Xiao Qi, why are these mice so crazy?" Tang Yu couldn't figure it out. He had no hatred and conflicts with these mice! What can they get when they attacked him and others so crazy?

"Master, if I guess correctly, these mice should be controlled by some of the Source Rat Hearts. Master, you carry the breath of the Source Rat Hearts, and you are felt by these mice. The Source Rat Hearts can only belong to the rat clan, so these mice will become very crazy." Xiao Qiyi explained seriously.

After hearing Xiaoqi's explanation, Tang Yu was suddenly a little amused. It turned out that the heart of the Source Rat was a terrifying thing! However, Tang Yu noticed what Xiaoqi said, the mice in front of him were all controlled by the Heart of the Source Rat. Can the Heart of the Source Rat still control the mind of the mouse?

Tang Yu raised his own doubts.

"Yes!" Xiao Qi nodded, "To a certain extent, the Heart of the Source Rat actually has its own consciousness, and it can also be regarded as a separate race, and this race is very xenophobic. There was a time when the ancient prehistoric world was almost destroyed by these source rats, including other monsters, which were deeply harmed by them. So I guess that the demise of the Source Rat actually angered the great gods of the ancient prehistoric world and asked them to take action at the same time. Otherwise, the power of the Source Rat clan would not have been impossible for the future, and there would be no news."

"So powerful?" Tang Yu was stunned, and was surprised for a moment and couldn't speak. He only thought in his heart that this source mouse is too powerful. It seems that the source mouse seems to be much more powerful than any divine beast!

Tang Yu narrowed his eyes, with an excited smile flashing in his eyes, thinking that if Xiaoqi could swallow all the hearts of the source rat, wouldn’t he be able to grow to this level? In the future, will Xiaoqi become his own thug, and no longer have to help him find treasure?

Of course, Tang Yu did not really regard Xiaoqi as a thug. Even the divine beasts on him, Tang Yu never thought so. He did not regard these guys as his pets, but as friends.

Well! Except for that little girl in Medusa!

When Tang Yu thought of Medusa, he felt depressed, and then threw the depression behind his head and continued to think about the problems in front of him.

Tang Yu thought of another question. If the Source Rat Clan is really so annoying, then after Xiao Qi swallowed the Heart of the Source Rat, would he be considered a member of the Shangyuan Rat Clan? If the great gods from the ancient prehistoric world wake up here and find that the Source Rat Clan has appeared in the world, will they take their anger to him?

"Damn, I want to achieve perfect success. Even if the great gods of the ancient world awaken, what can I do? Am I just a person who retreats when encountering this difficulty? Besides, I haven't collected all the hearts of the Source Rat. Even if I collect them, I may not necessarily become a source Rat clan. What's the use of thinking so much now! I'd better consider how to improve the attack ability of the formation!" Tang Yu slapped his forehead, his eyes became serious, and his brain turned quickly, thinking about how to improve the attack ability of the formation.

Suddenly, Tang Yu's eyes lit up and he thought of a good way, without touching the current formation, because the way he thought of was to set up a purely broken attack formation on the outside of the formation.

He noticed that these crazy mice were just attacking the formation madly on the front of the formation and did not move to the back of the formation. In other words, Tang Yu and others are now just fighting against the enemy head-on, and have not reached the level of being surrounded by enemies.

The only thing Tang Yu was worried about was that if he withdrew from the formation in front of him, it would attract the attention of those mice, which would be troublesome.

Tang Yu was a little regretful at this moment because when setting up the current formation, he only paid attention to his defense ability and attack ability, and ignored the concealment. Therefore, the mice could clearly see Tang Yu and others in the formation, and Tang Yu and others could naturally clearly see the group of mice outside.

Now that I want to modify the formation, it will be troublesome.

"Tang Tang, is there any way to hide our figures in the formation?" Tang Yu asked in confusion, but he had just finished asking, but he thought that this was wrong. If these mice could not see their figures, they would smell their breath to find them. At that time, Tang Yu left the formation, wouldn't they still be discovered? Unless, Tang Tang and the others still had the aura that attracted these rats, and at the same time, Tang Yu's own aura was completely blocked.

Tang Yu hurriedly said, "Forget it, don't block you too, just block me alone. Can it be done?"

"Simple." Tang Tang smiled and asked in confusion: "Dad, why are you blocking yourself? Do you want to go out?"

"Well!" Tang Yu nodded, "The attack effect of this formation is too poor. I want to go out and reset a pure attack formation. Otherwise, these mice will not know when they will be completely eliminated!"

"Is there any danger?" As soon as he heard that Tang Yu was going to do this, Shu Shuirou and his girls became panicked.

"Don't worry! As long as Tang Tang gets it well and blocks all my breath, there should be no problem." Tang Yu shook his head and said.

"Dad, it's done!" Tang Tang suddenly spoke.

"Are you okay?" Tang Yu was a little surprised, and didn't see anything Tang Tang did! He looked down at himself, and it didn't seem to be blocked!

Tang Yu looked at Tang Tang with a puzzled look on his face.

"Dad, just believe Tang Tang! Will Tang Tang harm Dad?" Tang Tang blinked, and a mist of grievance appeared in his eyes.

"Of course not." Tang Yu shook his head, then proved with his actions that he believed in Tang Tang and walked out of the formation directly.

After leaving the formation, Tang Yu carefully observed the mice in front of the formation. After finding that they did not notice him, he quickly arranged a new formation.

Because considering that it is a pure attack formation, the formation set up by Tang Yu this time is very sharp, and you can feel the murderous intent by just one glance. Of course, Tang Yu has not arranged it yet, so it is not like this. But after he has finished setting it up, the effect of the formation will be quite amazing!

There was no consideration for defense, only attack, so the formation was arranged very quickly. When the formation was formed, the entire canyon was trembling.
