When Beitang Yu watched the Black Water Snake frantically attack the large array set up by the people of Tianyin Temple, he was also slightly interested in the large array laid by Tianyin Temple.

However, although the Great Array of Tianyin Temple is powerful, it is really much worse than the Great Array of Heaven and Earth, and Beitang Yu is not much interested after a few glances.

And Tianyin Temple defended the Black Water Snake three times, and was attacked by the Black Water Snake, and the big array was defended, basically even the masters of Qingyunmen did not dare to say that they could break it, but in front of the Black Water Snake, it was really not enough.

When Beitang Yu watched the Black Water Snake ravage the master of Tianyin Temple, Beitang Yu also flew directly into Tianyin Temple.

Inevitably jumped off the wall by the dog of Tianyin Temple, Beitang Yu did not expose any traces, and explored directly towards Tianyin Temple, and there were many places to explore, and finally let Beitang Yu explore the location of the fourth volume of the Book of Heaven.

"There are a lot of monks here. Beitang Yu looked at the great monk guarding here, there was not a word on the wordless wall, but Beitang Yu could find the words on it through perception, and it was necessary to use spiritual power to check it.

"Slash!"

Many flying swords flew out from Beitang Yu's body, and all of them killed these monks.

The people who can guard here are the hidden masters in the Tianyin Temple, and they really don't have to do it as a last resort, these monks will not act rashly, but when Beitang Yu's flying sword kills, these monks can't even react and are killed.

Beitang Yu really doesn't feel at all about killing these big monks whose strength is weaker than himself, the strength of these monks seems to be good, but in Beitang Yu's eyes, there is really no pressure at all.

After killing these guardian monks, Beitang Yu collected the fourth volume of the Heavenly Book on the wordless wall.

When Beitang Yu returned to the outside of Tianyin Temple, the Black Water Snake had been almost abused, and after the Great Array was broken, these great monks could be said to have almost no resistance in the face of the Black Water Snake, and they were ruthlessly slaughtered by the Black Water Snake.

"Alright, let's go, there's nothing we need here. Beitang Yu said to the Black Water Snake.

The Black Water Snake was a little reluctant to let go of the remaining monks, and left the Tianyin Temple directly with Beitang Yu, not caring at all about the situation that Tianyin Temple was turned upside down by Beitang Yu and the Black Water Snake.

When Bei Tang Yu left with the Black Water Snake, he naturally found a place to comprehend the 5 volumes of the Book of Heaven, which is worthy of being a secret book for cultivating the truth, and the top cultivation technique in the world of Zhu Xian is better than the sword technique obtained by Bei Tang Yu in the world of fairy swords.

And under the simple comprehension, Beitang Yu already knew the power of this Heavenly Book, and just a little cultivation had improved Bei Tangyu's strength a lot.

After cultivating for a while, Beitang Yu left the Zhuxian World with the Black Water Xuan Snake and returned to Earth.

From the departure of Beitang Yu to the return, nothing much happened on the earth, and the monster seemed to have discovered that the human race was also getting stronger after the previous attack, so he felt that he might not be able to do it at the moment, so he naturally had to prepare for a big wave.

And the return of Beitang Yu made many people breathe a sigh of relief, after all, Beitang Yu said that he was going to retreat, but no one knew how long Beitang Yu was going to retreat, in case of a monster, then relying on the current Zhang Guo's 3 students of the flying sword class and those who have not yet graduated from the ninjutsu class and magic class, it is really difficult to block the attack of the monster.

And once the monster can't stop the attack, then the countries can only drop nuclear bombs and other super weapons, but in this case, then the people can't hide it.

Although it has been a year or even two years since the monster appeared, under the concealment of various countries, there have been no accidents, at least the news has been tightly covered, and no one knows about the existence of the monster at all.

But this situation is based on the fact that Beitang Yu can easily kill monsters, and once there is no Beitang Yu to make a move, then it is not easy to easily kill monsters.

When Bei Tang Yu came out of the retreat, he immediately went to the training camp, and at the same time, Bei Tang Yu taught the Book of Heaven to Zhao Min and the three daughters, so that they could cultivate well.

Zhao Min's 3 women have been following Bei Tang Yu for the longest time, and the 3 women's cultivation talents are not too strong, so they haven't cultivated well, but they can cultivate, plus the resources provided by Bei Tang Yu, at least they have been cultivating for a while.

At this moment, with the heavenly book provided by Beitang Yu, Zhao Min and the three daughters naturally cultivated happily.

The Book of Heaven is very profound, but it is also very clever, and the cultivation of the Book of Heaven even in the earth plane has made the strength of Zhao Min's three women improve rapidly.

And Beitang Yu also brought the Book of Heaven to the training camp to let Zhang Guo's flying sword classes practice, so that their strength was also growing rapidly.

Beitang Yu didn't lose anything on this trip, not only did he obtain more sophisticated exercises, but he also brought back the Black Water Snake and the Yellow Bird.

At this moment, the Black Water Snake and the Yellow Bird were still in the Water Spirit Bead and the Thunder Spirit Bead, and Beitang Yu also had the intention to let them show their faces on the earth plane.

"Xiao Zhang, during my retreat, didn't those monsters appear again?" asked Beitang Yu to Zhang Guo.

"Yes, instructor, none of them have reappeared, but according to the analysis of the researchers above, if the monster star wants to transform a batch of stronger monsters, then it should be soon. Zhang Guo nodded.

During the period of Beitang Yu's retreat, Zhang Guo and the others were naturally cultivating hard, even Beitang Yu's strength had to be retreated, where did these students have the qualifications to be lazy, if they dared to be lazy, even if they were not discovered by Beitang Yu, the people above would scold them to death.

"Really, let's take a look, and those scientists who study space, have you figured out that space passage?" asked Kitado Yu.

Dealing with monsters is secondary, this way to cure the symptoms rather than the root cause, the important thing is to find a way to destroy that space channel, and at the same time strengthen the earth's space, so that the monster star cannot be connected to the earth plane.

"Well, there's no news yet. Zhang Guo also shook his head and said.

The knowledge of space, at the moment, is a collection of scientists from all over the world in this area and do not have much clue, and it is indeed very urgent, but the scientific and technological things are not in a hurry, so they can only be taken one step at a time.

Bei Tang Yu briefly asked about the situation, and then inspected the cultivation results of the students, Zhang Guo and other flying sword classes had good cultivation results, and the other two classes also cultivated well, which made Bei Tang Yu very satisfied.

A few months later, the space passage in the Pacific Ocean stirred again, and a new batch of monsters appeared.
