The dark clouds flew extremely fast and soon overtook the convoy and reached the place where Bai Yuqi and the others were staying.

At this time, everyone also saw clearly what this dark cloud making noisy noises was... birds! All kinds of large and small birds gathered together to form a dark cloud!

This "bird cloud" is composed of various large and small birds of different species. The small ones are no more than the size of a fist, and the large ones even have a wingspan of three or four meters, just like the legendary roc!

Not only the sky, but the dust rising on the horizon also indicated that a large group of things was coming, but it was not moving as fast as the flying birds, so it was not clear what it was for a while.

But as the sun gradually rose, a strange motorcade arrived in front of Bai Yuqi and others.

They are also bamboo trucks, but compared with those equipped with steam engines, these trucks dragging long carriages are driven by animal power.

And what's strange is that the animals on the trailer are all kinds of strange, including the "six different" takin, which is bigger than a cow, and the "four different" serow, which is about the same size as a donkey.

There are also various types of cattle, horses, donkeys, deer, antelope, musk deer, deer, muntjac... and even fat wild boars!

After all, steam engines are complicated to process, and the number of master craftsmen who have mastered [metal dissolution] and [shaping] is limited, so naturally the output of steam engines is also limited.

Being able to supply the needs of each department is the result of these master craftsmen working hard all the time in the past few months.

Bai Yuqi, who had already mobilized all the steam trucks that could be mobilized, had no choice but to use animal power first.

Fortunately, they plundered a large number of cattle and horses from the Turkic grasslands, and the number of these large livestock was very sufficient.

As for the takin and serow, as well as the antelope, forest musk deer, deer, muntjac and wild boar, these are purely resources that are put to their best use.

Anyway, they are just idle in the Zhongnan Mountains. If they don't want to be reduced to food livestock and wait for death, then they can come out and work hard to earn money for themselves.

If it weren't for the bamboo rat pulling the cart, it would be a bit much.

Bai Yuqi wished that even the almost overpopulated bamboo rats that had bred in Kuyu City were tied up with ropes and pulled the cart.

He had been away for three months, and no one helped hold "sacrifice" for those bamboo rats. The disciples of [Shennongmen] raised them and did not dare to kill them.

The result is that these bamboo rats, who eat and sleep, and then give birth to babies after sleeping, have multiplied and almost filled the empty dormitories in Kuyu City!

So after Bai Yuqi returned, he immediately held a "collective funeral" for the bamboo rats.

While freeing them, he also freed the [Shennong Sect] disciples who were almost exhausted from the overflowing bamboo rats and were vomiting blood.

Due to the upcoming plan, Bai Yuqi needed a lot of manpower, and he really didn't have time to serve these cute but edible rats, so he had to send them to death first.

The "heroic sacrifice" of millions of bamboo rats is not without value. After recruiting a large number of people into the mountains to organize funerals for the bamboo rats.

Bai Yuqi obtained tens of millions of soul energy and directly upgraded himself to [Level 1 and Level 8] in one breath. The upper limit of arcane energy soared from the original 100+300 to 3300+3300x3, which was an increase of dozens of times!

In this way, his spellcasting ability has once again returned from the embarrassing situation of insufficient arcane energy after promotion to a state where spellcasting is no longer so constrained. Coupled with the increase in the concentration of [Arcana Particles] in the Zhongnan Mountains and Gyeonggi areas, it is enough to cope with

What he has to do next.

The bamboo carriages dragged by groups of large and small livestock were also modified. The carriages were transformed into rows of grids, filled with... bird's nests made of hay balls?

And the creatures raising dust on the horizon finally revealed their true colors in front of everyone who was looking around... There were chickens, ducks and geese all over the mountains and fields. Looking at them, it was impossible to tell how many there were!

The monarchs and ministers of the Tang Dynasty couldn't help but be stunned, and subconsciously turned their heads to look at Bai Yuqi.

Bai Yuqi did not explain, but just showed a smile. This is the biological locust extermination army he prepared for the locust plague!

After all, the thunderstorm convoy of artificial locust extermination can only attract and destroy large swarms of locusts, but it cannot completely exterminate all locusts.

Therefore, as long as the Thunderstorm convoy eliminates more than 60% of the high-density locust swarms wherever it arrives, it will be considered as completing its mission.

As for the remaining scattered locusts, the thunderstorm convoy cannot stay in one place for a long time, waiting for them to slowly gather and die.

Therefore, when the thunderstorm convoy swept through like a sweep, the remaining 40% of the locusts could only be captured manually by the people of the Tang Dynasty.

But how many people can be caught?

Before the next wave of locusts forms, if their numbers are not suppressed below the safety line.

Even if Bai Yuqi, a living god, was present, he could only watch the raging locust plague helplessly.

Don’t forget, 1,000 locusts can produce 62.5 trillion offspring within four generations, not counting the number of newly bred locusts.

So, in order to avoid such a terrible scene, Bai Yuqi did everything possible. Not only did he gather the chickens, ducks and geese that had been raised in [Shennongmen], he even personally inspected the entire bird group in Zhongnan Mountain.

"Combat mobilization" was carried out.

This is why they are now seeing this spectacular bird migration scene.

As the sun rose, large numbers of locusts hiding in the mountains and fields began to move again, and quickly gathered into large swarms flying all over the sky.

But unlike before, where humans could only look at the sky and sigh in wonder, the same overwhelming flocks of birds rushed up to kill them, just like using an eraser to wipe away the dirt on the blue sky canvas, and wiped out those flocks in one sweep.

of locusts.

And the flocks of chickens, ducks and geese that surged past like a tidal wave rushed into the fields, leaving only locusts everywhere they passed!

Compared with humans who still need to bend down to catch locusts, these poultry are much more efficient in clearing locusts. They will swallow them with one click and stretch their necks!

Seeing the poultry spreading across the land like a tide, the emperors and ministers of the Tang Dynasty were stunned.

Because the chickens and ducks passed by, none of the locusts jumping all over the ground could be seen, leaving only...chicken droppings all over the ground!

The thick layer of locust carcasses that had been crushed to pieces on the road was pecked clean by the poultry without any waste.

The birds are responsible for clearing the migratory locusts in the air, while the poultry are responsible for clearing the nymphs jumping all over the ground. The coordinated operation between the air and the ground is surprisingly effective!

A large number of disciples of the [Beast Control Sect] blew a kind of sharp bamboo whistle, driving and guiding the birds and poultry to start their long-distance migration like herds.
Chapter completed!
