There is a huge disparity between the enemy and the enemy, and in the face of the enemy beasts all over the mountains, no one is not disgusted, even the iron-backed ape with a head of five or six meters high, he also feels his legs stinging.

Fortunately, the old man is calm, he has already commanded several major battles, and although there are many enemies in front of him, it is not enough to make him panic.

Under his command, the 900 men were divided into two parts, one part formed a battle formation, standing at the mouth of the valley to block the enemy group, while the other part drew the iron axe from his waist and rushed into the nearby mountain forest, knocking down the trees to the ground.

The old side thought of building fortifications on the spot, and if trees were used to build a guardrail, the current situation would definitely be improved.

Although at the entrance of the valley, he could block all the enemies dozens of times outside the valley, but the number of bows and arrows was not enough to support the end of the war, so he could only find another way to stabilize the situation in front of him, and then find a breakthrough from the outside.

His plan was to dig a pit to keep the enemy at bay and then drag it on the other side of the pit, but he tried, and the soil was so hard that it would be very difficult to dig with tools like pickaxes.

So, he retreated and chose to cut down trees to build fortifications.

Trees were lifted out of the woods, and the old man communicated with the leader of the Distant Ancestors for a while, and then the ironback ape joined the ranks of building the fortifications.

The iron-backed ape, which is more than five meters tall, has a strength that cannot be compared with humans, and it takes three or five people to carry the tree, the iron-backed ape can easily lift it with one hand, and then with a little effort, it can easily plunge the sharpened tree into the hard soil.

With the addition of the iron-backed ape, the speed of the fortifications increased sharply, and the fence of the first row was finally closed twenty minutes after the battle began.

In the process, more than a thousand of the green-armored beasts had fallen in a pool of blood, and the corpses of the green-armored beasts were piled up at the entrance of the valley like sandbags, blocking the entire entrance.

The green-armored beasts, which were not yet dead, struggled to crawl out of the pile of dead beasts, but the corpses of their companions, like mountains, pressed against them, making it difficult for them to move.

At present, the advantage is still in the hands of the old man, and through the suppression of the bow and arrow, the entrance to the valley is still firmly held in his hands.

After repelling a wave of blue-armored beasts, the old side sent out fifty men, and their mission was to go to the front to pick up arrows.

The number of arrows was extremely limited, and the old party had to take this risk, and a few of the more unlucky people, in the process of picking up the arrows, were swallowed by some seriously injured and immortal, but driven by hatred to become extremely crazy.

The old man then ordered the spear array to press forward twenty meters to meet the arrow-pickers who had returned with a full load.

In the current situation, the old side cannot replenish the arrows with other methods, only in this way.

The scales of the green-armored beast are indeed hard, and these arrows that have been used once look much duller, which is very different from the new arrows.

Of course, to a large extent, the current iron-smelting technology of human beings is also very limited, and it is impossible to make iron arrowheads with greater hardness.

While fighting with the enemy group, the old side methodically built the fortifications, and when everything stabilized, the old side handed over the command to the North Shadow Wuyu, and immediately went to find foreign help.

……

Spring Breeze Valley.

Gong Zhimu stared at the river, this is a small river less than 100 meters wide, all winter, it was in a dry state, now, after a few spring rains, this thin little poor immediately ate into a fat man, the river down the mountain, in some places with a large verticality, but also formed a small waterfall.

"Can water rotate?" Gong Zhimu is a little nerve-wracking, recently, the Lord has given him fewer and fewer hints, and many times, only a rough name is given, and he is asked to find a way to get it.

He knew that the Lord Almighty would definitely make those things, but why not just give him the drawings and let him build them according to the drawings?

He couldn't understand it, but the order had to be obeyed.

"Use the thrust of water to convert water energy into kinetic energy!" These are the original words of the Lord, but he understands every word and every word, and when they are together, they cannot be understood.

What is thrust, what is water energy, what is kinetic energy, these things are very profound to him.

Fortunately, this time the Lord did not let him make anything, but only let him observe the water and understand the water.

But what is there to observe in the water, he is a little puzzled by the second monk, at this moment, a roar, from a certain mountain rushed out of a certain mountain, a bat with its wings outstretched, more than three meters in size, Gong Zhimu was so frightened that he almost fell into the river.

Immediately afterward, a giant bat appeared in the sky, and they flew straight to the southeast without looking at the wood.

The old man possessed a mutant who was shaped like a bat, like a Western vampire.

Lao Fang originally hated this form, but this was the only unit that humans could fly, so he kept all of them.

The number of mutants in this group is not large, and there are more than 300 people in addition to the old, weak, sick, disabled and pregnant.

At this moment, these three hundred mutants are each carrying a big burden, and in the baggage is a bundle of bows and arrows, with a total number of about 20,000.

These are extremely important supplies, and the old side must send them to the battlefield as soon as possible.

With this batch of arrows, the pressure on the North Fish must be much less.

……

Looking at the green armor beasts that were surging like a tide, he was not shocked in his heart, and he was still standing on the front line, giving orders briefly.

Not long ago, the old side handed over the slightly stabilized situation to him for command, and he jumped out of the battlefield to seek assistance on the periphery.

The battle was still fierce, the pikemen had already suffered casualties, and the desperate blue-armored beasts braved the rain of arrows, jumped over the trees, and plunged directly into the spear-lined enemy formation, burning their own lives to make a final attack on the enemy.

The North Immortal has no expressionless face, and when there is a vacancy in the pikemen, he orders someone to fill it.

The casualties of the green-armored beasts were naturally much greater than those of the pikemen, and their corpses had already blocked the entire valley mouth, and the green-armored beasts in the rear had to climb over the corpses like climbing a mountain, and then charge towards the enemy formation.

The Northern Immortal Fish moved the formation backwards to prevent the enemy beasts from condescending and causing psychological pressure on their soldiers.

At this time, a new force joined the battle, and thirty iron-backed apes, more than five meters tall, casually uprooted the trees in the valley and smashed towards the group of green-armored beasts that rushed over.

The two hundred distant ancestors also drew their bows and arrows and shot at the green armor beasts, their bows and arrows were eliminated by the old party last time, so they were far from the North Dark Fish Department in terms of strength, and the arrows were not equipped with iron arrows, and in terms of penetration, they were also much worse.

But it's better than nothing, and if you're lucky, these arrows can also blind the eyes of the green-armored beast, and can also cause some damage to the enemy beast.

The momentum of the enemy beast is very fierce, although the casualties are huge, but the distance of dozens of meters gives them hope, a sprint can reach the enemy formation, why not fight to the death?

Looking at the endless herd of beasts, he knew that he couldn't last long, but he was not worried, the 'Lord' had also taught him the steps to defend against the enemy, and he believed that with the wisdom of the 'Lord', he would definitely be able to turn them from danger.
