Therefore, the number of demons is very large, but fortunately they do not have much combat experience and mainly rely on their own physical fitness.

This can be considered as the natural level of the demon race. They are born with good physiques. Before they cultivate to the foundation-building stage, their physical advantages can be clearly reflected.

For example, the Black Soul Tiger Clan is at the forefront of the demon army.

They are the most noble clan, so there are not many of them in the army, but they have extremely powerful strength. Relying on their naturally strong physique, they have far more powerful strength and defense than other elements of the same kind.

Those light bands can kill the surrounding monsters, but they are not enough to get rid of the Black Soul Tiger in one go.

The Black Soul Tiger clan rushed to the front and continuously launched attacks on the protective shield, while the other elements behind them followed closely behind, attacking under the protection of the Black Soul Tiger.

Their method of attack is just that simple, just by charging forward.

Relying on his strong physical advantage and enough strength to break up the enemy's formation, destroy the enemy's protective shield, and directly shatter the city's defense.

But it is obvious that they encountered a tough problem today.

No matter how hard they attacked, the protective shield in front of them could still be restored to its original state. There would be some cracks at the beginning, but it would soon return to its original state.

This situation was soon noticed by the demon clan.

Feng Jiutian looked at the protective shield in front of him and his expression became solemn.

"Beihua City's protective shield is truly formidable. I heard their city defense formation was originally developed by a formidable formation master, who personally directed its creation."

"Now it seems that this is indeed the case. It was I who underestimated their city defense formation."

Fengshan next to him said at this time.

"Our demon army has suffered certain losses. The first batch of troops at the front have almost been destroyed. If we can't achieve certain results in time, I'm afraid it will affect morale."

Feng Jiutian thought for a moment and said.

"There's no need to rush now. Since the protective shield of this city defense formation is so powerful, we might as well use these cannon fodder to consume them for a while."

"After they're almost exhausted, we'll have the Jindan masters dispatch and take them down in one fell swoop."

He didn't know much about Beihua City's defensive formation, so he wanted to consume its resources first and then launch a fierce attack.

The main reason is that Jindan masters cannot consume too much spiritual power, otherwise they may lack spiritual power when fighting with the Jindan masters in Beihua City later.

However, when he heard his words, Fengshan shook his head violently and pointed at the protective shield in front of him.

"Young Clan Leader, take a closer look at this shield. It's not that each attack is ineffective. It's just that the shield recovers so quickly that it appears to have no damage and still has plenty of energy."

"However, in reality, this city defense formation is probably even more powerful than we imagined. Perhaps this protective shield can repair itself by absorbing spiritual energy."

Fengshan studied military books intensively and had a deep understanding of many city defense formations, so he quickly figured out the clues.

After hearing this, Feng Jiutian observed carefully and found that it was indeed true.

His eyes suddenly widened and he nodded.

"That's exactly what happened. I didn't expect there was such a city defense formation. I was short-sighted."

Fengshan said comfortingly.

"The young patriarch is just a little inexperienced. Now that he knows the opponent's weakness, he can naturally solve it."

Feng Jiutian’s mistake was not a big problem, and only they knew about it. Feng Shan came here for this very reason, to prevent any other accidents from happening.

What's more, since we already know where the problem lies, Feng Jiutian must also know how to solve it.

Feng Jiutian closed his eyes to feel the spiritual energy of heaven and earth, and then opened his eyes again.

"I didn't sense any fluctuations of spiritual energy from the front. This proves that the other party must have concealed their aura, or they are not absorbing spiritual energy from the front to restore the protective shield."

"The most likely possibility is that their absorption location is in the rear. Although we have troops in the rear, they are not numerous, and there is only one Jindan strongman."

Feng Jiutian quickly figured out the best way now.

That is to directly choose to attack forcefully, forcibly attack the opponent's rear, prevent the opponent from continuing to absorb spiritual energy, and maintain the protective shield.

There is no other choice, because there is no other strategy to plan now. It would be fine if we knew it in advance, but now that the battle has begun, we must solve the problem through a quick battle.

Moreover, the defense in the rear should be relatively weak, because since it is the place where spiritual energy is absorbed, it is impossible to be fully covered by the protective shield.

This became an opportunity for the Jindan powerhouse to launch a surprise attack.

The third elder and the fourth elder soon appeared in front of Feng Jiutian.

Feng Jiutian behaved very respectfully in front of the two elders and spoke.

"Could the two elders please conduct a surprise attack on the rear of the fortress and lead the most elite troops to directly destroy the place where they absorb spiritual energy. This way, we can break through from the front."

The two elders nodded heavily.

"I will follow the orders of the young patriarch!"

After the two of them finished speaking, they took the elite troops of the Golden Phoenix Clan and began to head to the rear.

This is a surprise attack, and there must be elite troops guarding the rear of Beihua City.

However, this time, two Jindan powerhouses will go there, so it will definitely have a good effect.

At this moment, Feng Jiutian looked at Feng Shan next to him and said.

"How's the other matter going?"

Fengshan quickly understood what this meant and spoke.

"Don't worry, Young Clan Leader. We've already arranged for them to go in during the day, and they should be inside by night."

"Until now, there has been no news. It seems that the defenses in the human city are too high, so they dare not act rashly. However, the battle has begun now, and I believe there will be a result soon."

Feng Jiutian nodded and didn't ask any more questions.

The so-called other thing is naturally the assassination of Lin Donghai.

Lin Donghai is a big trouble for them. As long as this guy is alive, he will bring trouble to their demon clan.

After finally inflicting a heavy blow, they must take this opportunity to eliminate the opponent, otherwise the sacrifice of their Golden Phoenix clan's strong men would be in vain.

Now the strong man from the Qingqiu Fox Clan has already lurked in. What he needs to do next is to wait for the protective shield to end before launching a general attack.
