The range of the potion is limited, and it does not appear to have much effect on the incredible number of Sea Clan troops.

The problem was that Jia Zhengjin had already hoarded quite a terrible amount, because in all the pharmacies that had been built, he had bought any potions with negative effects before anyone else.

Immediately after the construction is completed, only the red and blue pills that restore health and mana are left to choose from, who can beat him?

And it is also a part of the gold coins drawn out by the coalition forces of the Human Empire, which can be regarded as filling one's own pockets, and it will not hurt at all.

Paralysis, poisoning, petrification, blindness, confusion, sleep...... All kinds of negative state elixirs were poured down by Jia Zhengjin, and the Sea Clan troops were immediately torn apart into a small combat area, and no matter how they commanded, they couldn't play a role.

When the potion ran out, Jia Zhengjin even used the bright red realm, shrouded a large number of sea clans and began to suck blood, which can be regarded as exhausting the means.

With his addition, the coastal defense line in the middle successfully blocked the crazy offensive of the Sea Clan, and even with the assistance of human magicians, the Sea Clan army was defeated and retreated.

But the coastal defense line in other areas is not so easy, even if there are strong people in charge, because it has to save effort to deal with the leaders of the Sea Clan and the eight generals, so it is basically blocked by fortresses and arrow towers, as well as cannon fodder kobolds.

In a few places, the Sea Clan's offensive was so strong that even the first line of defense had been breached, and Ruruto and an army of Imperial soldiers had to be sent to meet the enemy.

The fierce battles seemed to be endless, and no matter how many waves of Hai Clan troops were repulsed, there were always more Sea Clan troops appearing and marching like crazy.

More than two hours later, Jia Zhengjin was tired enough. He had to temporarily retreat and take a short rest on a floating defensive platform.

The endless black wave of the Sea Clan made him finally appreciate the spectacular scene of the million-strong army written in the history books.

"Lord Keane!" Donald immediately came over as he returned to the floating defense platform, "You've done a great job!"

"It's okay!" Jia Zhengjin drank a bottle of magic medicine and sat directly on the side, "If it weren't for the fact that after fighting with Beiluga, I couldn't exert my strength, how could this little battle be difficult for me?"

"Of course!" Donald didn't know that Jia Zhengjin was just bragging, and it was indeed a matter of course in his opinion, "But Lord Keane, you still have to save your strength to deal with the sea god, you can't use all your strength now!"

"I still have to help you as much as possible to deal with the sea god!" Tang Bing sighed, "I don't have a good way to deal with it for the time being...... As for the amount of stamina expended, it doesn't matter. Drink some medicine and you'll be refreshed and back into battle!"

"You'd better preserve your strength," Donald said worriedly, "Now it's just the vanguard of the Sea Clan, and the main force hasn't been on it yet! When the local main force appears, and even the leaders of the Sea Clan and the eight generals join the battlefield, we will not be too late to make a move!"

"Well, then I'll watch you fight here!" Jia Zhengjin nodded, "But you can also summon bats to help you and disrupt the enemy's sight." ”

"Then I'll continue to command the battle, Lord Keane, and rest here now!" Donald hurriedly turned back to the front line and continued to command the battle.

Jia Zhengjin drank the medicine, slowly recovered his mana, and then began to summon a large number of bats into the battlefield.

The war is getting more and more intense, and the Sea Clan's attacks are getting stronger and stronger. Even though the Mage Guild desperately resisted and the fortress tried to resist, it still couldn't stop the Sea Clan from destroying the Arrow Tower.

More and more arrow towers were destroyed in the first line of defense, and several strong fortresses were even crushed by brute force by some fearsome sea creatures. The kobold troops were also gradually unable to support it, and suffered heavy losses under the strong attack of the sea tribe creatures.

But even so, the Human Empire's coalition forces are still trying to hold on, desperately blocking the enemy army.

The kobolds have lost at least more than half, and about a quarter of the arrow towers that were built at great cost are now damaged. Many of the Sea Clans had already managed to cross the fortress and engage Ruluto and the Imperial soldiers of the Second Line of Defense.

In the magic duel, Donald's side was better. With the protection of this super strongman, there are no casualties. Other areas have already lost a large number of elite mages, and the scene is very tragic.

Finally, after about three hours of the Sea Clan's attack, most of the first line of defense of the Human Empire coalition army had been breached, and tens of millions of kobold troops were also annihilated after trying to delay!

The human mage, led by Donald, quickly retreated to the floating defense platform of the second line of defense. With a total of about 20 million troops from the Imperial Empire and Ruruto, they finally appeared as the second wave of the main combat force and fought fiercely against the Sea Clan.

Don't look at the total strength of the Sea Clan is not as much cannon fodder as here, they are really one enemy and ten in the sea, which is quite terrifying!

Of course, the previous round of offensive and defensive warfare still greatly reduced the number of Sea Clan's forward troops. In addition, about half of the arrow towers in the fortress are still trying to attack, and the army of the second defensive line is also fighting desperately. The number of Sea Clan vanguard units seems to have begun to decrease dramatically.

"Lord Keane!!" After another half an hour of fierce fighting, Donald quickly reported to Jia Zhengjin, "Look over there!"

Looking in the direction of his finger, Jia Zhengjin found that the rear replenishment line of the black and oppressive Sea Clan vanguard troops on the sea had been interrupted, and it seemed that there was no more except for those who were still fighting in front: "Have we successfully held off the attack of the first wave of Sea Clan troops?"

"It should be!" Donald nodded, but there was no expression of joy on his face, "but it's not so optimistic, I'm afraid the main force of the enemy army has already arrived!

As soon as the words fell, I saw that more Sea Clan troops had emerged at the horizon in the night through illumination! And this second wave of troops seemed to be even stronger than the vanguard troops, and the most eye-catching thing was naturally the several Sea Clan generals who were surrounded by the army, and there were countless giant whale-like existences.

"That's ......," Jia Zhengjin frowned and looked at the Sea Clan troops on the other side of the horizon.

"Eight Generals!" Donald said solemnly, "They have finally appeared, this is the regular army of the Sea Clan!"

"A vanguard army that is used as cannon fodder is so terrifying, and the combat effectiveness of the regular army is even stronger, right?" Jia Zhengjin worried, "Is there no problem with our army?"

"Don't worry, Lord Keane!" said Donald, "we've been prepared for a long time. Although I don't dare to say that we will definitely be able to defeat the main force of the Sea Clan, it is also certain that we will delay the time until the leader of the Sea Clan or even the Sea God appears! Our Human Empire Alliance, which has gathered all the strongest human beings, is not easy to bully! You just need to watch carefully and prepare to face the Sea God!"

"Well, I'll bother you next!"
