More than a dozen Goblins carried the ballista and set it down in the clearing of the forest.

This time, the ballista had three giant bow arms.

The three massive bow arms were arranged with two facing forward and one backward.

The ballista before him was designed by Li Meng based on the structure of a triple-bow ballista.

But it was only similar; there were significant differences in many details.

"String it up!"

This time, the triple-bow ballista had two winches.

Six Goblins hurriedly moved forward, panting as they cranked the winches.

The immense tension made the bowstring and bow arms creak.

With the help of the roller structure, the power of the three bow arms was concentrated together.

It took over a minute for the bowstring to be fully cocked.

Li Meng lifted the giant bolt, carried by three Goblins, with one hand and placed it into the loading slot.

This time, the bolt was even larger, about 2 meters long.

After completing the preparations for firing, the experiment officially began.

Li Meng aimed the ballista at a large tree several hundred meters away.

"Whoo!"

Li Meng took a deep breath.

His gaze was fixed on the target tree not far away.

With a forceful squeeze, he pulled the trigger.

"Whoosh!"

The ballista shook.

The piercing sound of the bowstring snapping back echoed through the forest.

A black streak shot through the air, heading deep into the forest.

"Boom!"

Almost instantly, a loud crash resounded from deep within the forest.

A large tree three hundred meters away collapsed with a thunderous crash.

The bolt pierced straight through the tree, and the massive impact shattered the trunk.

Unauthorized duplication: this narrative has been taken without consent. Report sightings.

After penetrating one tree, the bolt continued with undiminished momentum, embedding itself into another tree a hundred meters away.

A third of the bolt was buried in the trunk.

The terrifying power left the Goblin minions dumbfounded.

The commotion here caused chaos and disorder in the tribe.

Li Meng was also startled by the terrifying power.

A tree that would take three people holding hands to encircle was pierced straight through by the bolt.

If it were fired in an arc, the range could easily exceed a kilometer.

"But the bow arms need to be thicker!"

Earlier, when the bowstring was being cocked, Li Meng heard the cracking sound of the bow arms breaking.

With the current strength of the triple-bow ballista, the bow arms would break after only a few uses.

The limit wasn't the bowstring but the bow arms.

If the bow arms were thickened, the ballista's power would be even greater.

Because the power of the crossbow is related to the tension of the bow arms.

"Very good, not bad, take it back!"

With that, Li Meng returned to the carpentry workshop to continue strengthening and adjusting the triple-bow ballista.

Time passed little by little, and day after day went by.

On the afternoon of the fifth day, in the carpentry workshop.

"Boss, do you think this will work?"

Gobu Ge, along with a group of Goblin minions, found the boss in the carpentry workshop.

Li Meng, who was assembling the triple-bow ballista, put down his work.

Li Meng took the harpoon bolt from the shoulders of three Goblins with one hand.

He weighed the bolt in his hand, nodding in satisfaction.

Although the harpoon tip was a bit rough, it was usable.

"Very good, how many have you made?"

Gobu Ge chuckled, counting on his fingers.

When he reached ten, Gobu Ge looked confused.

"Alright, put them all down, that's enough!"

Gobu Ge's face lit up with joy, and he quickly instructed the minions to put down the harpoon bolts from their shoulders.

Looking at the three massive ballistae in the wooden house, Li Meng grinned.

With these three ballistae, they could set off tomorrow.

About half an hour later, Li Meng left the carpentry workshop.

"Benben, let's go!"

Benben had been waiting at the entrance of the carpentry workshop.

With Benben in tow, Li Meng headed towards the direction of the throne cave.

By now, the sky was gradually darkening.

"Bai Ling?"

On the way back to the throne cave, Li Meng encountered Bai Ling.

Bai Ling, escorted by several Goblins, was heading towards the throne cave.

"Master!"

Seeing the master approaching, Bai Ling slightly lowered her head.

At this moment, Bai Ling was already sporting a big belly.

In the second week after returning to the tribe, the female Lizardmen in the throne cave became pregnant one after another, thanks to Li Meng's efforts.

Li Meng glanced sideways at the depths of the forest behind Bai Ling.

"Did you go to the Iron Cave?"

The expansion work of the tribe had been completed half a month ago.

Now, all the male Lizardmen were working over at the Iron Cave.

Once the first lactation period began, the female Lizardmen would continue to lactate.

Li Meng glanced at the bamboo tube in Bai Ling's hand.

He could smell the rich scent of milk from the bamboo tube.

It was clear that Bai Ling was delivering milk.

Ever since Li Meng allowed the female Lizardmen to deliver milk, it had become a routine for them.

They milked in the morning and delivered the milk to the male Lizardmen in the afternoon.

Before dark, they would each return to their own caves.

Since the offerings were mostly couples, each male Lizardman could drink the milk of his own wife.

As for whom Bai Ling's milk was delivered to, it wasn't hard to guess.

It was certainly given to the weakest male Lizardman.

Li Meng didn't bother to interfere with the Lizardmen's way of supporting each other.

Male Lizardmen having milk to supplement their nutrition and maintain their health and strength wasn't a bad thing.

Bai Ling nodded slightly.

Li Meng didn't say much more.

The two walked together towards the direction of the throne cave.

"Master, is the cave for smelting iron?"

As they walked, Bai Ling suddenly asked.

Li Meng turned his head, looking at Bai Ling with a half-smile.

"Why do you think it's called the Iron Cave?"

The master's response made Bai Ling's heart sink.

A trace of disbelief flashed in her eyes.

Bai Ling wouldn't be surprised if any Barbarian in the Goblin Forest was smelting iron.

But Goblins smelting iron was unimaginable.

How could Goblins, with their intelligence, learn the iron-smelting techniques of humans?

Even the swamp Lizardmen knew nothing about iron-smelting techniques.

"I told you, I'm a smart Goblin. There's nothing impossible for me."

Bai Ling lowered her head slightly, not daring to meet the master's gaze.

With her head down, Bai Ling's eyes were filled with murderous intent.

The presence of the Big Goblin beside her was a disaster for all intelligent races in the Goblin Forest.

Although Bai Ling kept her head down, Li Meng still sensed the killing intent emanating from her.

Looking down at Bai Ling beside him, Li Meng grinned wickedly.

"You can try, but if you fail, I'll make you watch as all your kin are eaten alive!"

Upon hearing this, Bai Ling, with her big belly, trembled.

Her legs went weak, and she almost stumbled to the ground.

Li Meng stepped to the left to support Bai Ling.

"Master, Bai Ling wouldn't dare!"

Li Meng grinned without saying more.

The two, each harboring their own thoughts, walked together in the tribe.

In the following days, Li Meng didn't rush to leave.

The next morning, he went back into the carpentry workshop.

Having the triple-bow ballista wasn't enough; they also needed a means of transportation.

Not only did the ballista need a transport tool, but the tribe's freight transport also required a means of transport.

In ancient times, there was only one best means of transport.

And that was a wheeled carriage.
