Heavy punches are like rain.

It seemed as if they were descending and attacking in pieces, but in fact only Gu Zeyan and the other four knew the most. The Beidou God Fist was all hitting their Xuanwu battle formation with extremely regular and frequency.

However, the arrival interval between each fist is only 0:00 seconds, and the naked eye cannot tell clearly. It looks like a mess of fists attacking randomly without any rules.

One minute.

They persisted for a whole minute under the attack of the Beidou God Fist and endured at least 7,000 to 8,000 punches. Everyone consumed a lot and was as tired as a dead dog.

Fortunately, the Xuanwu battle formation that the four of them worked together was amazing, and finally barely supported it.

However, even after passing the level, they knew very well that in fact they had lost, and the power of the killing formation of the Ten Directions Purgatory Demon-killing Formation was beyond their imagination.

If the monsters of the demon race are really trapped in the array, there is no chance of letting them appear together, nor can they give them permission to use open space rules.

Therefore, if only one half-step demon emperor-level monster faced such a formation attack alone, he would have been knocked into a slag long ago.

There is no doubt that the effect of the Ten Directions Purgatory Demon-killing Formation has obviously reached the expectation of being able to kill the half-step demon king. Yang Fan did not brag, he really succeeded!

"Huh, I finally pushed it over. It's time to end now, right?"

Gu Zeyan couldn't help but raise his hand to wipe the sweat on his forehead. The minute just passed, he was so tired that he had been living for most of his life, and he had never been beaten by so many fists at the same time.

"It should be over. If any half-step demon king is here, they will die long ago." Zhao Xuewen said: "I have to say that these two sets of chain formations are indeed amazing!"

The four big guys were all panting, thinking that the killing formation had completely ended. When they were about to go out, their eyes were blurred and the surrounding environment changed again.

"Damn it! Come again?"

"No, didn't you say it's only one minute? It's been two minutes since then. You can't be without any integrity in life!"

The four big men changed their qualities at the same time, and they wanted to break through the air and leave directly, but they couldn't help but feel curious, wanting to know the next formation changes and the corresponding level of damage and killing.

After all, this was the opportunity to test the formation that they consumed a half-step demon core at the level of the Demon King. If they retreated so easily, they always felt a little sorry for Lan Yuanqing.

"Or why, let's try again?"

Gu Zeyan took a deep breath, turned his head and asked the three old friends beside him.

"Anyway, the killing array has been activated, so it will be a waste if you don't try it once. As long as we are more careful, there shouldn't be too much danger."

Gu Zeyan himself didn't believe this.

The Beidou God Fist just now did not explode the turtle shell on their heads, and the danger was at least four stars!

"The old principal said it's right. It's not easy to start the formation once, so you can't just waste it."

Liu Silong raised his hand and wiped the blood from the corner of his mouth, and agreed with a calm voice: "Since you have come, you can rest assured. If you really encounter a crisis of death, it will not be too late for us to break through the air and leave again, so don't rush to this moment!"

"Now, let's see what the next killing formation looks like!"

While talking.

Zhao Xuewen suddenly felt weak in his legs, and he collapsed on the ground with a thump, his face flushed and dizzy.

At the same time, Hu Chen quickly set up three will barriers in front of him, and cried out his companions around him to remind him:

"Be careful, we are surrounded by unknown poisonous miasma. If nothing unexpected happens, the killing formation at this level should be mainly poisonous!"

Gu Zeyan said: "This is a poisonous spider array, poisonous miasma is second. Everyone should be careful of the poisonous spider silk that will appear at any time in the future..."

In the next thirty minutes.

Gu Zeyan and the other four experienced a total of 36 killing formations, including the Poison Spider Array, the Wanxiang Array, the Soul-Devouring Array, etc.

The duration of each formation is one minute. Within every minute, the four people are surrounded by dangers. On several occasions, their lives are suspended by a limit, and only a little bit will be in danger of life.

Fortunately, every time they see that they are about to face danger in their lives, Yang Fan will quietly make a fine-tuning of the power of the formation so that they can all pass through it safely.

In this way, Yang Fan hugged them little by little and experienced the next killing formations, and carefully interpreted all the thirty-six killing formations hidden in the Ten Directions Purgatory Demon-killing Formation.

After thirty-six minutes of continuous sweeping, Yang Fan's formation experience and formation experience soared to the top, and he was very rewarding.

finally.

Thirty-six minutes later.

Gu Zeyan, Liu Silong, Zhao Xuewen, and Hu Chen, four half-step emperors, broke through all the killing checkpoints and helped each other out of the portal opened by Yang Fan for them.

Each of them was already ragged and majestic. They were seriously injured, and their qi and blood were weak. Even the soul and sea of ​​consciousness seemed to have suffered extremely serious damage.

Without saying a word, Yang Fan directly performed advanced healing techniques on the four of them. He was afraid that if he delayed any further, the four big men would completely stop because of poisonous gas attacking the heart and exhausting their blood.

"You used advanced therapy for the half-step emperor Gu Zeyan (seriously injured and endangered). The treatment was successful. Gu Zeyan (seriously injured and endangered)'s injuries were partially improved, with mental power +4, mental will +4, skill proficiency +6."

"You have used advanced therapy for the half-step emperor Liu Silong (seriously injured and endangered) and the treatment was successful..."

“…”

That's right, all four half-step emperors were seriously injured and endangered. If they hadn't had their own strong foundation, they would have probably not been able to survive and come out of the formation.

It's really miserable!

Lan Yuanqing and Sima Xuefeng were extremely worried when they looked at people. Unexpectedly, they just asked these four seniors to try the power of the formation, but they were so miserable.

However, this also shows from another aspect that the power of the Ten Directions Purgatory Demon-killing Array arranged by Yang Fan is unexpectedly good. In the future, they no longer have to worry about a large number of half-step demon emperors coming to attack and destroy the city!

"Huh! I finally came back to life!"

A few minutes later, Gu Zeyan stretched his body easily, no longer having the serious injury and fatigue that he had just now.

"Thank you, Yang Fan. If you weren't here this time, we old guys might have been beaten back to our original form and obediently returned to Wanshou Pavilion to retire."

Yang Fan smiled shyly: "Professor Gu is polite, this is what students should do."

"I wonder if the ancient professors are still satisfied with the power of this killing formation of the Ten Directions Purgatory Demon-killing Formation?"

Gu Zeyan's mouth twitched.

It’s not just satisfaction, but it’s just unforgettable.

Their brothers almost died directly inside. They were all stunned and were so frustrated that they were almost depressed.

For one minute, who would have thought that each killing array would continue to attack for one minute, making them a target. After experiencing destruction and ravage over and over again, it would be a blessing to be able to come out alive.

"It's amazing and amazing! It's not an exaggeration to call it the nemesis of the half-step emperor! With it, Jinghua City will be worry-free!"

Gu Zeyan was not stingy with the praise of the Ten Directions Purgatory Demon-killing Formation. In fact, this is indeed the case. This is definitely the most awesome and powerful killing formation they have ever encountered in their lives.

For a long time, unless the emperor came in person, their Jinghua City would inevitably become the city with the highest security factor on the entire Federation and even the entire Origin Star.

The merits are immeasurable!

Gu Zeyan, Liu Silong, Lan Yuanqing, etc., all the big bosses and seniors present looked at Yang Fan with such extremely shocking and admiring eyes.

At the critical juncture when the emperor's agreement was not there and the war between human and demon clans was about to begin, Yang Fan timely constructed and arranged a super city-sharing formation that was enough to keep all demon clans from the city, effectively protecting the personal safety of trillions of ordinary residents in the city.

Such a feat and such a merit are not an exaggeration.

Although the actual inventor of the Ten Directions Purgatory Demon-killing Formation was Huyan Jingde, who had already made ancient times, Yang Fan, who actually promoted it, made an indelible contribution.

After all, it was Yang Fan's first thought of using the Ten Directions Purgatory Demon-killing Formation to defend the city and put it into practice.

Moreover, it is absolutely not easy for anyone to fully build and activate a super giant formation built around the outer city of Jinghua City within seven days without any mistakes.

"Thank you, Yang Fan!"

Gu Zeyan looked at Yang Fan very seriously and thanked him sincerely: "Because of your selfless dedication, in the federal realm, billions of human races will be blessed by the Ten Directions Purgatory Demon-killing Formation and will no longer be threatened by the battle to destroy the city!"

With the example set by Jinghua City, I believe that it will not take long before such a formation of the Ten Directions Purgatory Demon-killing City will be completely popular in the entire federal territory.

Yang Fan's reputation will surely be known to the entire Human Federation!

"If the old sayings are heavy, students dare not take credit for it."

Yang Fan shook his head and said, "This improved version of the Ten Directions Purgatory Demon-killing Formation is Professor Hu Yan's lifelong hard work. The students just passed on this formation according to Professor Hu Yan's will and will."

"So, the person who truly selfless dedication and immeasurable merit should be Professor Hu Yan, and students dare not be greedy for merit."

Next to them, Che Hongyu, Fang Zhe, Qian Tongfang and others who had just teleported out of the core of the formation were all moved by Yang Fan's sincere words.
Chapter completed!
