Chapter 588: An Unexpected Upgrade

With Jia Zhengjin's current equipment, he would be able to fight high-level monsters, let alone insects?

Although the giant insects were densely packed and the number was astonishing, none of them could withstand his attack.

The insects that appeared this time included giant centipedes, silver-armored spiders, mutant frogs, and many other groups, with thousands of them.

Facing such a huge army of insects, Jia Zhengjin tried his best to keep the farmland and prevent them from destroying the tree of life.

Lay mines, throw bombs, explode arrows, rain arrows and keep all giant insects out from all directions. He even did not hesitate to use the staff of corpse poison to resurrect the giant insects that were killed to become his own zombies, forming a powerful zombie army to guard around the farmland.

The accumulated battle lasted for more than an hour, and Jia Zhengjin kept dropping bombs and creating zombies. In the end, the farmland is full of giant insect zombies and various insect corpses that have been blown up to pieces.

When he was so tired that he was about to collapse, he finally successfully defended this wave of defensive battle.

[System] Congratulations on repelling the giant insect army and successfully defending the farmland!

[System] The tree of life is growing vigorously, and the growth cycle has been shortened to 47 days!

[System] The tree of life needs irrigation to continue to grow! If the sapling is not irrigated with the spring of life before it grows up, the sapling will wither and die!

[System] You have completed the random task - guarding the farmland, and gained 500,000 experience points!

[System] You have upgraded!

The continuous system prompts made Jia Zhengjin a little apprehensive, and then he remembered the accumulation of hunting monsters, especially the lobster monster Nadu, who killed an unknown number of Nadu larvae, and had accumulated a lot of experience. In addition to the experience points of the thousands of giant insects just now, and the 500,000 experience points given by this random mission, it has been successfully upgraded!

It takes more than 3 million experience points to upgrade from 16 to 17, which is enough before you know it!

What made him most happy was that the growth cycle of the tree of life was also shortened to 47 days, which was only one and a half months!

The stark contrast between thousands of years of growth and one and a half months is unbelievable! That's the beauty of the system.

In other words, within a month and a half at most, Jia Zhengjin can also have his own tree of life, and then get more spring water of life!

But now it must be irrigated with the spring of life, otherwise the tree of life will not grow up after the growth cycle is reached, but will wither and die immediately.

Jia Zhengjin didn't want to waste so much energy and get nothing in the end.

He immediately took out the spring of life gifted by Xiangier from his backpack, used a manuscript to remove the stone and brick walls around the farmland, and then carefully poured a bottle of spring of life at the root of the tree of life.

[System] The tree of life has been irrigated, and the power of life has increased by 20%! Please continue to irrigate until its life force is fully replenished!

One bottle is not enough! Jia Zhengjin was very heartbroken. One bottle of such a precious spring of life can only increase the progress by 20%.

But thinking that the tree of life can make more spring water in the future, he gritted his teeth and took out more spring water.

40%, 60%, 80%, 100%!

After irrigating five bottles of life spring water, the power of life of the tree of life finally reached 100% full value.

[System] The power of life is strong! The tree of life will grow up smoothly after the growth cycle!

Five bottles of spring water of life! Use up half of it in one go! Jia Zhengjin's heart ached, but he felt better when he remembered that as long as he persisted for a month and a half, he would be able to have a tree that produced the spring of life.

However, during this period of time, I am most afraid that other creatures will destroy the farmland and the tree of life, so I must not be negligent! Jia Zhengjin quickly used the staff of corpse poison to transform all the insect corpses on the scene into zombies, making them hide around and form a huge protective circle, guarding the tree of life at all times.

At the same time, I also thought about it. After returning, let the dryad come to station here, and have it to cooperate with the guards.

In addition to being bulky and unable to enter the water, the dryad is actually very powerful. With it, plus thousands of insect zombies, it can definitely ensure that the tree of life is safe and sound!

Of course, to be on the safe side, in order to ensure that there is no powerful monster threat, Jia Zhengjin will also specially send several generals to patrol nearby to drive and destroy the monsters that enter this area. Maybe I have to ask Liv to help, it will be safer with her, a ninth-level powerhouse, guarding it!

The tree of life is really important to Jia Zhengjin, because the spring of life is related to the issue of longevity! Many powerful people in this world passed away at important moments when they crossed ranks due to lifespan problems. Some of them could obtain a longer lifespan from the eighth level to the ninth level, but they fell before they successfully broke through.

In addition to being used by Jia Zhengjin himself and his family, the Fountain of Life can also be used to win over more masters of various races and enhance the strength of Sacred Dragon City!

After upgrading to level 17, he got 1 skill point, plus the book of skill points he got before, Jia Zhengjin now has a total of 2 points that can be allocated.

He has long thought of adding a route, which is to build a science laboratory as soon as possible, and then add various science and technology to make the development of Holy Dragon City even better!

Now the premise building of the science laboratory is only the machinery factory, Jia Zhengjin added the points without hesitation, and lit up the icon of the science laboratory.

And the remaining one skill point, of course, is decisively added to the science laboratory.

After successfully unlocking the machinery factory and science laboratory, two new blueprints appeared in the building bar. This means that he can quickly build these two buildings in the city.

It is useless for a short period of time to create a science laboratory. After all, all its technologies require points, and unless Jia Zhengjin continues to upgrade, he can freely add points.

However, the machinery factory is a very good building. With it, many simple machinery can be manufactured, and it is also the most important place for post-manufacturing robots!

It seems that we must seize the time to upgrade the treasure, and get as many skill points as possible to increase the science. However, there are so many things going on recently, especially the dark dragon is like a shadow that suppresses Jia Zhengjin, it is difficult to find time to concentrate on fighting monsters and upgrading! First of all, it is necessary to recruit suitable candidates to inherit Tangier's knowledge and magic, so that he can grow up to be able to compete against the Dark Dragon, so as not to destroy the world and make himself useless in the future!

Just as he was thinking, the ugly monster who had been sleeping on Jia Zhengjin's shoulder suddenly opened his eyes, flew straight into the air and made an unpleasant "quack" sound towards the rear, as if reminding him of something.

This ugly monster slept on Jia Zhengjin's shoulder all day long, and even after the fierce beating just now, it didn't wake up. The sudden reaction is so big, it seems that there is a problem!

Jia Zhengjin immediately waited for the battle, and at the same time quickly learned the flash skill book of the general category, just to increase his combat effectiveness!
