After sending Chu Xuening away, the stone that pressed on Yu Hao's heart finally fell, and now he could let it go.

As an intellectual young man in the 21st century of the earth, Yu Hao still knows a little knowledge. The best way to deal with a species is to introduce the natural enemies of that species.

Now Yu Hao is worried about whether the introduction of other species will cause biological invasion, in which case the Northern Regions will be miserable again.

"Alas, no matter what, invasive species is better than being eaten by bugs, it seems that this is the only way. ”

"Yes, now there are more than 5,000 pheasants, which can barely support them for a while, but the insects that the chickens eat are a little less! ”

"System, buy all my remaining system coins into birds and beasts, and give priority to those who eat insects. Now Yu Hao can only rely on the acceleration time of the system pasture to quickly breed a large number of birds.

"According to the current situation of the host, it is recommended to have three tired, the first is the cardinal, which eats a very large amount, and can eat thousands of them every day according to the calculation of insects, and one of the three system coins. ”

"The second type is the giant quail, which can reach eight or nine meters in size as an adult, no matter how big the insect is, it will not refuse to come, and it will be a five-system coin. ”

"The third type is the Hongxi woodpecker, the insect killer, the adult Hongxi agrees to reach more than ten meters, and the insect extermination is very fast five system coins. ”

Yu Hao fell into deep thought, the Zerg who came to attack the city this time generally did not exceed one meter, and more than ten centimeters accounted for the majority.

"Forget it, how many system coins do I have at the moment?"

"There are currently 501 Syscoins left on the host. ”

"501, well, the system buys twenty giant quails and twenty red woodpeckers, and then a hundred cardinals. Oh yes, half male and half female. ”

In an instant, there were more than a hundred birds and beasts in Yu Hao's pasture, and Yu Hao nodded excitedly.

Cardinals reproduce very quickly, and can have three litters per year, each of which can live independently within a month. So the cardinals buy a little more, and the base will become very fast after tomorrow.

"Knock, knock, knock. ”

"Damn, why did you attack again so quickly, I had to rush over as soon as possible, I had to buy time. ”

Without the slightest hesitation, Yu Hao hurriedly rushed towards the Xuanwu Gate.

"City Lord, the Zerg is coming, and we can't resist the Zerg's attack at all. The commander looked at Ma Wenxuan with an unwilling face.

"Alas, I didn't expect our ending to be like this, it's a shame. Alright, brothers, let's live and die together today. ”

"Live and die together!"

"Live and die together!"

"Wen Xuan, I have a way to deal with this insect tide. Yu Hao panted and ran up the city wall.

"What, Lord Yu, what you said is true?" Several of the commanders present, as well as Ma Wenxuan, Bai Wucheng and the others looked at Yu Hao excitedly.

"That's right, but whether or not this solution can be implemented depends on how we perform next. ”

"Brother Hao, you say, we will definitely do it. ”

"Yes, even if we try our best, we will definitely do it. ”

"The core of this plan is one word, delay, drag it until tomorrow, we can at least resist the enemy's attack, push it until the day after tomorrow, I am sure that I will break through the insect tide, and the longer it drags on, the greater my certainty. ”

Everyone is silent, they can't even survive today now, it's hard to drag it out until tomorrow, it's not realistic at all.

"Announcing this news, people's desire to survive is a very powerful force, and whether they can persist or not depends on today. Ma Wenxuan is becoming more and more of a strategist, a commander who hides behind the scenes.

"Yes, give them a little hope so that someone will work hard and not give up. After thinking about it for a while, Yu Hao agreed with Ma Wenxuan's method, and only when there is hope will there be motivation.

"You guys go down and spread the word, at least let everybody hear the news. ”

"Yes. ”

"Hey, have you heard, as long as we delay until tomorrow, we can resist the attack of the Zerg, and the longer we delay, the better the chances of winning. ”

"Really, is this news accurate?"

"I've also heard that this is what the owner of the field said, as long as we drag it down, he can solve the insect tide. ”

"Great, since the owner of the field said it, it should be true. ”

"Haha, we still have hope, we must hold on until tomorrow. ”

"Yes, we will drag it out, and we will drag it out to protect the safety of our families. ”

"Hold on!"

"Hold on!"

Seeing this scene, several people laughed, and the momentum was very strong, and the chance of letting go also increased.

After the Zerg were assembled, they launched an attack on Tianfeng City under the command of a blood worm, and this time the insect tide came even more violently.

Under the nervous gaze of everyone, Yu Hao came to the edge of the city wall, and with a wave of his right hand, five thousand words of pheasants appeared neatly arranged together.

The three leading pheasants are the first generation of the initial pheasants that Yu Hao has entered the pasture, and with the blessing of the ranch, they have now reached the king level, the strongest rooster has reached the level of the fourth order of the king level, and the remaining two have reached the third order of the king level.

There are more than a hundred of the rest of the general-level pheasants, and the rest are all spirit-level. It's also a very strong reinforcement.

The insects that rushed to the front saw a group of pheasants that suddenly appeared, and their backs were stunned, causing the back to rush up and have a stampede accident, killing thousands of insects.

The rooster at the head looked at the rushing insects with a proud face, and as its cry sounded, all the pheasants in the first row grew their mouths, and the fireballs in their mouths erupted towards the insects.

Then he changed to another queue, not to mention, this time he successfully resisted the attack of the bugs.

"Giggles. Looking at the insects that rushed to the front of him, the pheasant king also gave the task of charging, and all the pheasants rushed towards the insects.

There are a lot of bugs that are usually eaten by them, so these pheasants don't take the bugs in their eyes at all.

It's a pity that the number of insects is too much, and their roots can't be controlled, and after a while, the pheasant flock will be flooded by the insect tide, and Yu Haozhi is distressed.

However, the attack of the pheasant still played a big role, delaying the attack of the bugs.

"Brothers, let go!" The Terran side also began to attack, although it was still very difficult, but at least it was still held, but it was a pity that the pheasants, only three king-level escaped back.

On the Terran side, it was completely crippled, and now there were less than 20,000 people left who could fight, and the rest were all killed in battle, and no one was injured. Even the people who used to be in their hands are now all gone.

Looking at the ruined city walls, everyone fell into grief, and the comrades who were still by their side before could not even find their bones. There was not a single person under the city wall except for the corpse of the worm, not even a single bone.

In the future, I, Yu Hao, must be the maker of the rules, and whoever bullies me will be killed. ”

Yu Hao waved his hand and collected the pheasants into the pasture, and he could strengthen a little.

The pheasant returned to the pasture and immediately relaxed, the battle just now scared it to death, and when he saw the insects in the future, he would have to take a detour, and he couldn't afford to provoke it.

A few small bugs emerged from the pheaant's feathers and fell to the ground without attracting the slightest notice.
