When more zombies poured under the city walls, Fang Hao finally knew what their siege tactics were.

At the corner of the city wall, the corpses piled up higher and higher, and in a short time, they were several feet high.

Dense zombies layer upon layer, layer upon layer, all of them looking up at the city, waving their arms, with only one goal, that is, to rush to the city, tear human bodies, eat human flesh and drink human blood, and fill their hungry and thirsty stomachs.

The walls were now replaced by strong warriors with swords in their hands, and their expressions were solemn, waiting for the great battle to come.

Fang Hao looked at the pile of zombies under the city, and his heart was itching, so many zombies, killing them casually is a lot of experience.

Their density is too high, if you throw a few grenades into it......

The grenade cannot be manufactured, it can only be purchased from the system shop.

As a consumable, a grenade only costs 50 points of energy, which is 5 crystal nuclei, which is ridiculously cheap.

However, in most cases, Fang Hao didn't use grenades, firstly, the sound was too loud, and secondly, it would cause some damage to the terrain, so Fang Hao thought that he would never use grenades here.

But in this case, grenades are the perfect fit.

Fang Hao bought ten grenades, and then took a brief look at the instructions for use, the use of this kind of grenade is very simple, pull out the safety pin, open the fuse and throw it out.

Fang Hao secretly glanced at Yun Lei, casually touched it into the backpack, and then took out a grenade, then turned on the fuse and threw it down.

As for holding it in your hand and waiting for a few seconds, it is completely unnecessary, and the zombies will not hide anyway.

"Brother Fang, what are you doing?" Yun Zhong also inspected the situation of the corpses below not far away, and when he noticed Fang Hao's strange movements, he immediately asked.

Fang Hao pointed towards the city with his hand, but did not speak.

Yun Zhong looked down and happened to see the scene of the grenade exploding.

"Boom!" With a bang, the grenade exploded in the pile of corpses, metal fragments splashed, and with a powerful shock wave, more than a dozen zombies were blown out on the spot.

Although the power of the grenade was insignificant in front of so many zombies, the pile of corpses like a hill collapsed downwards in an instant.

After all, the corpses are loose individuals, like a pile of sand, as long as you poke under the pile of sand, the entire pile of sand will be affected, resulting in a crack or collapse.

"Brother Fang, is this a grenade! It's awesome, come, give me one, let me have a good time! Yun Zhong rushed to Fang Hao at once.

Fang Hao said: "I don't have many here, and you haven't played with grenades, what if you accidentally hurt others?" ”

"Just teach me what I can!" Yun Zhong said hurriedly.

Helpless, Fang Hao had to take out another grenade and explain the operation methods and precautions to Yun Chong.

"It's so simple, do you still need to learn! Come, look at me! ”

Yun Zhong followed the steps Fang Hao told him and threw the grenade into the pile of corpses under the city.

With a "boom", the corpses were blown down a little bit.

"It's so cool! It's so much fun to kill zombies like this! I said, Brother Fang, if you sell us more grenades, these zombies will all become scum! Yunzhong exclaimed excitedly.

However, Fang Hao felt a pain in his flesh, a grenade was not worth much, but the zombies killed by the grenade were a lot of experience.

When the first grenade he threw down exploded, he saw that his experience bar had suddenly increased. This shows that there must be a lot of zombies killed by this grenade.

According to the instructions given by the system, there are 1,500 small steel balls in each grenade, with a killing radius of 10 meters and a critical safety distance of 30 meters, that is, even if they stand on the city wall and the grenade explodes on the ground under the city, they may be hit by waves, of course, this is only theoretical data, and this possibility is very small in practice.

At the moment of explosion, the dense steel balls in the grenade will fly out at an extremely high speed, which can easily penetrate the human skull.

That's why it's so lethal.

And the upgrade method of throwing grenades is both convenient and fast, Fang Hao felt that he could buy more grenades in the future, and throw them into the pile of corpses when he saw them.

Yun Lei also looked at Fang Hao in surprise at this time, grenade? There are more and more novelties in his hands.

"Brother Fang, do you still have grenades? Hurry up and throw it! The corpses are coming up! ”

Under the city wall, the corpses have been gathered, and they are working hard in one place, and their hearts are used in one place, like countless silk threads, which are being kneaded into a thick rope.

If someone were outside the city at this time, and looked at the corpses from a distance, they had already formed an arrow shape at this time.

This arrow points to the location of Yun Lei, the center of the city tower.

Fang Hao saw that the siege tower that the zombies had built with their bodies was already less than ten meters away from the city.

He touched his backpack twice, pulled out two grenades, turned on the fuse, and threw them into the pile of corpses.

"Boom! Rumble! ”

After two loud bangs, Fang Hao saw that his experience bar had increased by a large margin again.

It's level 28, and it's only a little bit of experience left.

Fang Hao only cared about looking at his own experience bar, and didn't look at the situation of the zombies at all.

However, Yun Zhong saw that the two grenades landed very well, and they just landed in the middle of the corpse pile, and the corpse pile sank violently, and the height was two or three meters lower in an instant.

Fighting with corpses at night is not about killing as many zombies as possible, the important thing is the word "drag", as long as it can be dragged until dawn, these zombies are all floating clouds, and the threat will be weakened several times at once.

Since this was the case, Fang Hao wanted to upgrade anyway, so he threw down all the grenades he had just purchased one after another.

Finally level 28, and two more levels are level 30.

"Keep throwing! Brother Fang, keep throwing it! Yun Zhong saw that the pile of corpses had been blown down again, and shouted at Fang Hao excitedly.

Fang Hao spread his hands: "It's gone!" ”

He definitely couldn't turn on the infinite grenade mode in front of so many people.

Without grenades, the corpses piled up frantically again, and in a short time, the zombies at the top were about to rush up the tower.

Fang Hao felt that the submachine gun team should have opened fire at this time, but Yun Lei did not give the order.

Suddenly, a zombie jumped up from the pile of corpses, put his hands together, and grabbed the battlements of the city wall, and when it wanted to jump up to the city with his strength, a strong man stabbed it with a sword, and hit it in the throat, and the unlucky fellow who was the first to rush to the city immediately fell.

With the first, there will be the second, the determination to overthrow human domination is unstoppable, and the zombies can never be killed......

One zombie after another, like a mountain of gold, rushed up the city tower and rushed towards Yunlei.
