The points of the upgrade, Jia Zhengjin directly added to the [machine tool unlock], which is a very important equipment.

Perrin was sent home, and Christina immediately took over treatment.

Jia Zhengjin himself did not rest for a few minutes and immediately returned to the north gate.

Sure enough, the wave of Spike larvae rushed out of the cave and attacked the city gate in a very frenzied manner. However, most of them hit the wire grid, and as a result, they were instantly blackened by the high-voltage current. As for the rest of the people who rushed to the gate, they were slaughtered by the bombs of kobold crossbowmen and kobold slingers.

Speaking of which, this kind of Spirai larvae seems to be not too terrible except for being fearless of death and terrifying numbers!

The kobold crossbowman killed the Spire larvae, and you gain 100 XP......

Jia Zhengjin's experience points began to grow wildly again, which made him start to expect the more Spire larvae to come, the better!

However, the battle lasted for about half an hour, and when his experience bar had risen to half again, the huge hole ** suddenly sounded that dull and terrifying voice again.

Strange things have happened!

The insect tide that was not afraid of death just now, and was constantly surging like a tide, immediately turned around, broke away from the battlefield at an extremely fast speed, and moved towards the cave in an uproar!

Jia Zhengjin was dumbfounded, watching the insect tide completely disappear in front of him, but he didn't dare to be careless. He immediately ordered the defense of the North Gate to be strengthened, and ordered the people in the city not to approach the vicinity of the North Gate for the time being.

After making sure that the Spirai larvae had completely retreated, Jia Zhengjin led his troops out of the door and hurriedly groped in front of a corpse.

It turns out that the Spire larvae have no loot on them!, but they can use a dagger to collect some strange silk.

For strange silk, Jia Zhengjin is not in great demand. After all, the hunting team can bring back a lot of silk threads when killing centipedes, which is enough for the daily needs of the textile factory.

However, the experience of these Spice larvae was something he needed.

And the most important thing is that the north gate has such a big pothole. If you don't try to destroy the insects inside and seal the hole, who knows if these terrifying insects will hollow out the underground of the Holy Dragon City? Not to mention that if the city collapses, it will be dug through the refuge passage, and the insects will flood into the city will be a catastrophe!

However, after the battle just now, Jia Zhengjin was tired enough that he had to rest for at least a few hours to recover. The same goes for his main force, the Fake Dragon, who is obviously unable to continue fighting for a short time.

Jia Zhengjin, who was anxious, thought about it, and said in his heart, can the tree spirit help him get rid of these insects?

He immediately went to the fairy garden and asked the forest elves inside.

As a result, the elves vetoed him, telling him that not only would the dryads not only be unable to deal with the tide of Spires, but might even be devoured by the insects.

This answer made Jia Zhengjin quite depressed, but if you think about it, it is also. Although the dryad is powerful, it still can't resist in the face of bugs, not to mention the countless terrifying bug tides!

Is it really just waiting for yourself and the fake dragon to recover?

"That's right!" suddenly had an idea.

The proboscis bear is also a fire-type monster, and the flames it spews are only slightly inferior to those of the fake dragon. Let Vera take the Proboscis into the cave and sweep through the Spires below!

But after thinking about it, he shook his head again. It's true that the proboscis bear can be used as a combat power output, but it can't fly! Such a high cave, it is so big and big, not to mention whether it will fall to its death, even if the water is deep enough to keep it from hitting the ground, I am afraid it will not be so easy to come up when the time comes!

This method still doesn't work!

What should I do?

Jia Zhengjin thought hard, since he couldn't go down, he had to bring them up!

After thinking about it, I thought of the six-headed ice sculpture after being tamed.

He immediately took out all the ice sculptures and hurried to the north gate, where he had Vera and her proboscis bear called.

"Vera, you'll be in charge of controlling the proboscis bear in a moment. Jia Zhengjin ordered the werewolf, "I will let the ice sculpture fly down to lure the insect tide! Once the insect tide appears, you will immediately make the proboscis bear breathe fire! If this place cannot be defended, immediately flee back to the city and use the barbed wire grid to block the other party!"

"Yes!" Vera nodded respectfully.

Vera and the proboscis bear alone are obviously of limited use. So Jia Zhengjin summoned the kobold slinger troops over and asked them to guard the edge of the pit together. As soon as the insect tide appears, make them drop improvised bombs immediately!

Now the stocks of bombs are running out, only 436 remain. After all, a bomb explosion can kill at least hundreds of Spire larvae, and more than 400 bombs, tens of thousands of Spire larvae are not enough to explode!

I just don't know how many Spice larvae there are, and if there is a next wave of explosions?

No matter what, he must act immediately! He can't allow such a big worm nest to exist under his city!

Vera, Proboscis Bear, and Kobold Slingers are all ready, and Kobold Crossbowmen are ready at the edge of the pit.

Jia Zhengjin looked back at the city gate that was very open, and if he couldn't withstand the insect tide for a while, he would immediately withdraw his troops to the city, but don't forget to open the door, and as a result, his troops would be harmed!

With everything ready, he let the six ice sculptures begin to execute their plans, and one after another fluttered their wings and flew towards the bottom of the cave.

After ten minutes, he finally heard the cry of an ice sculpture below.

Standing on the edge of the cave and looking down, I saw that the ice sculpture gradually appeared in front of me, flying upwards at a very fast speed.

At the same time, the terrifying insect tide reappeared, climbing up the wall at an alarming speed.

"Get ready—prepare—attack!!" Seeing that the insect tide of Spirai larvae was getting closer and closer, Jia Zhengjin immediately ordered loudly.

"Boom, boom!boom!" The kobold crossbowmen were the first to start, their crossbow arrows shooting wildly from top to bottom.

The kobold slingers also immediately took action, took out improvised bombs from the bamboo baskets behind them, and quickly threw them towards the insect tide in the cave.

"Boom, boom, boom......" Explosions came and went, and for a time the smoke of gunfire was everywhere.

【NEWS】The Kobold Slinger has killed the Spire Larvae, and you have gained 100 XP!

The kobold slinger killed the Spice larvae......

In front of Jia Zhengjin's eyes, the virtual interface began to be frantically swiped by experience points. Hundreds of Spice larvae were blown up, causing his experience to grow at a rather terrifying rate!

However, although the power of the bomb was terrifying and the lethality was strong enough, the insect tide was still surging upwards without fear of death, and soon reached the vicinity of the cave entrance!

"Kobold crossbowmen retreat first!!" Jia Zhengjin immediately retreated towards the city gate as he spoke, "The kobold slinger retreats to the vicinity of the city gate and continues to attack! Vera controls the proboscis bear to breathe fire!"
