But to Yang Song, the Food Replacing Pill formula was just a simple and ordinary pill formula. If this was put in the cultivation world, it was a thing that could be bought at a super cheap price.

Anyway, since it was ordinary for Yang Song, it wouldn't be a problem to sell it to the government. Of course, he would sell it at a very high price. After all, its value was there.

So he simply said to Yang Haonan, "You can sell it to them, and I believe you know the value of this formula, so I don't need to tell you what to do."

"Yes, father," although the answer he got from his father was quite unexpected, Yang Haonan still nodded, anyway.

After hanging up the phone, Yang Song got up and went to the White Dragon Abode.

This time, he came to the White Dragon Abode to refine Advanced rank talismans.

After sitting down, Yang Song took out many talisman papers and thought of the useful and practical Advanced talismans that he should refine.

It did not take for Yang Song to think of several types of them, such as the Lesser Fire Dragon Talisman, Storm Maker Talisman, Blazing Thunder Talisman, and so on. There were also some supportive talismans such as the Lesser Heaven Speed Talisman, Golden Bell Talisman…

After he thought of all the ones he wanted to refine, Yang Song began to refine them.

The Advanced rank talismans were harder and took longer to refine than the Basic rank talismans.

However, it was still not that difficult for Yang Song, who had already mastered the refining technique to the perfect state.

As soon as he started to draw the first symbol, Yang Song's attention was instantly gathered and his hands flowed as smooth as water.

It took Yang Song a minute to refine an Advanced rank talisman, and in this one minute, it also consumed him a lot of True Energy.

When morning came, Yang Song finished refining each type of talismans.

"But it really drained me, huh?" Yang Song sighed and closed his eyes as he started to restore his True Energy again.

To refine these talismans, Yang Song's True Energy had been exhausted several times. Now, his True Energy was completely drained from his Dantian.

The next day.

Yang Song truly finished refining all the necessary talismans and each type had several of them.

After refining the talismans, when Yang Song was about to close his eyes and started cultivating instead, he suddenly paused his action and came outside and looked in the direction of Martial City.

In the sky over there, there was suddenly a burst of explosive energy fluctuation.

…

Martial City.

Out of blue, a sharp air defense siren sounded throughout the entire city.

At the same time, official warnings similar to the previous omni-channel, including mobile phones, computers, and TVs alike appeared.

The abyssal demons struck again!

Yang Song quickly rode his sword over at a full speed.

When approaching the direction of the energy fluctuation, he noticed that the sky was solemn and looked in another direction.

Because there was the same but much weaker energy there.

No, not only in these two places but also in the other directions!

Yang Song's perception ability far surpassed any mystic warrior, so he could feel farther and more.

More and more… more and more…

The energy intensity was higher for those who were closer and slightly weaker for those who were far away.

Soon, dense energy fluctuations of different strengths and weaknesses appeared in all directions, even on the sea east of Martial City, there were energy fluctuations!

This was undoubtedly a full-scale invasion!

If the last time the abyssal demons came to the world was a large-scale attack, then this time, it was a full-scale invasion!

Finally, a loud noise appeared in the sky above Martial City accompanied by a shock wave of energy, and the whole Martial City was plunged into a state of huge panic!

Yang Song hurriedly urged the Blue Bolt Sword to fly faster and went to Li Wanjing's place.

At this time, three huge spatial cracks, which should be the abyssal demons' world passage, appeared in the sky above Martial City, and the surroundings of the three spatial cracks were even densely covered with abyssal demon creatures!

The last time the abyssal demons struck, over the city of Martial, there was a super protective energy shield arranged by Three Stars Masters.

The giant sword of water of the elemental body of Three Stars Masters instantly killed more than half of the abyssal demons in an instant.

Today, the super energy shield was no longer available, and there was no barrier between humans and abyssal demons.

As if the abyssal demons seemed to receive some kind of order, they began to attack the ground overwhelmingly.

The battle between the human race and the abyssal demons, after many days, once again started over Martial City!

Missiles, various mass-murder weapons…

When higher-ups received the news, they instantly realized the level of danger and asked the Grandmasters and various organizations to take action.

The figure of high-level mystic warriors such as mages and ability users traveling through the sky was like a meteor.

Thousands of mystic warriors in various departments of Martial City were very eye-catching.

A huge-scale battle between humans and abyssal demons, with heaven as the camp and earth as the field, began!

From the sound of the air defense sirens to the start of the war, in just a few minutes, everything was so sudden, fierce, and cruel!

There were more and more mystic warriors joining the battle, and there was also a steady stream of abyssal demons coming out of the spatial cracks.

The scale of the war was getting bigger and bigger…

The sky above Martial City had been covered with various explosions and rain of dead bodies!

Suddenly, a dazzling green light quickly rose from the ground, like a green rainbow circling the radiant sun.

Immediately after that, that dazzling green light formed the appearance of a giant leaf with a sharp edge and traversed hundreds of meters.

The giant leaf rushed quickly with an even more dazzling green light at the center.

Wherever the giant leaf made of green energy passed, many abyssal demons would die.

No abyssal demon could stop it!

Profound Leaf Master – Xiang Qingsu!

Xiang Qingsu's one person and one leaf directly reversed the entire battle.

This was the power of the A-rank ability user!

In the general rank used to represent all kinds of warriors, the world decided to divide it into simple ranks from the lowest rank, which was E-rank, to the highest rank, which was S-rank or possibly higher than that.

A 1st Tier Warrior was an E-rank mystic warrior, but a 9th Tier Warrior was a D-rank. A 1st Tier Master martial artist was a true D-rank. The Grandmaster stage was equivalent to A-rank approaching S-rank.

With Xiang Qingsu joining the battlefield, the balance of the Martial City battlefield seemed to have begun to shift towards the human side.

However, the abyssal demon group did not just have the flying ones.

Just when the battle was about to enter the decisive stage, the land of Martial City began to shake violently.

Then, a huge monster resembling a lizard drilled out of the ground!

The roar sounded like an offensive war declaration horn. Behind it, countless monsters squeezed out like ants!

But this was not the only one!

A similar scene was staged at multiple places in Martial City at the same time.

However, after the appearance of the ground abyssal demons, a large number of warriors among humans, under the coordinated command of the energy formation of multiple B-rank mystic warriors, gathered and attacked towards the ground abyssal demon passage.

The nearest ground abyssal demon passage site to Yang Song, thousands of people from the Abyssal Demon Slayer Corps were in groups, advancing all the way.

However, despite the precautions, the exact location of the ground abyssal demons' appearance was still unpredictable, so people were caught off guard.

Compared with the air abyssal demons, the destructive power and threat of the ground abyssal demons were much higher.

Seeing this situation, under Xiang Qingsu's high-pitched command, a group of B-rank mages and ability users used all their strength to speed up the progress of the end of the air battlefield.

However, there were three spatial cracks in the sky above Martial City. If Xiang Qingsu went to the ground, it would be difficult to completely defeat them in a short time.

But as just everyone was in a state of nervousness, seven different colors of light appeared in front of everyone.

When they saw this, everyone was instantly excited!

The seven Grandmasters were here!

Then, without a word, the seven Grandmasters divided into two groups as one group joined the battle in the air, and another group descended to the ground.

With the addition of the seven Grandmasters, the human side gained the upper hand.

However, there was one thing that everyone had not noticed yet. That was, the boss on the abyssal demon's side had not appeared yet!
