Tree plants can't be used, but Ye Chen also has two attack skills, Lucky Beauty Flower and Stinger Vine.

Among the two skills, the Lucky Beauty Flower is a control attack plant with a gambling surname, and the control skills are basically ineffective against the boss, planted out, and the output is not high, I'm afraid he will use up all the 50 seeds of the Lucky Beauty Flower, and he may not be able to kill the koala.

Therefore, what Ye Chen wants to use is a stinger vine.

After Ye Chen had an idea, he immediately did not hesitate to destroy the remaining two fifth-level durian bomb trees in one go, and planted three seeds of stinger vines on the ground at intervals!

It takes more than an hour to cultivate the fifth-level durian bomb tree, but the attack is basically ineffective against the koala, although Ye Chen is distressed, there is no way.

A minute passed, and the three stinger vines on the ground had already grown, and when Ye Chen saw this, he immediately pulled the koala onto the stinger vine that he had planted in a long straight line.

The three stinger vines were planted in a straight line by Ye Chen's cave, and the koala followed on the stinger vines, and dozens of poisonous injuries immediately appeared on their heads.

The attack of the stinger vine is not high, and it does not actively attack monsters, and only when the monster steps on it, it will cause not too much poison damage to the monster.

However, the most powerful part of the stinger vine is not in the damage, but after the monster is poisoned, the movement speed will be reduced by more than 30%!

The koala's speed slowed down suddenly, and Ye Chen didn't use duckweed grass at this time, so he could ensure that he wouldn't be caught up by the koala.

However, the skills of the poisonous surname are the easiest to pull hatred, and before the koala has taken a few steps on the stinger vine, it turns around and begins to attack the first stinger vine fiercely!

A **100 damage rose from the head of the stinger vine.

Ye Chen's stinger vine is only level three even under the level blessing of the Eternal Stone, with a total of 7000 HP, and the vine plant's own defense is quite low, if you let the koala attack, it won't take a few seconds, and the stinger vine will fall to the ground, after all, this plant is not as good as a knight, just like an ordinary player, and can't stand a few attacks from the boss.

However, when the koala launched an attack on the stinger vines, Ye Chen immediately turned on the hatred priority mode, and a withered light smashed down, and the koala immediately ran towards him.

But what gave Ye Chen a headache was that the koala didn't run a few steps before he was once again pulled away by the first stinger vine. If it is a normal attack plant, it is determined that such a thing will not happen, so the attack defense is not high, but it is easy to pull hatred of poisonous plants, and botanists have to be quite troublesome to use.

A third-level stinger vine was about four meters long on the ground, and the koala was attacking at the very end of the first stinger vine.

According to Ye Chen's observation, when the koala first walked a distance of one meter on the stinger vine, it was pulled away by the stinger vine, and when Ye Chen used the hatred priority mode to attack, the koala walked another three meters, and the hatred was pulled away again.

Priority hatred needs to be used once every ten seconds, with the HP of the stinger vine, even if Ye Chen turns on the mud wean grass to speed up the HP recovery of the stinger vine, it is still unable to resist the koala attack in ten seconds, the koala attack is not high, but the defense of the stinger vine is lower, and the stinger vine must have more than 9000 HP to resist the koala for ten seconds.

After getting rid of the stinger vine, the poisonous state of the stinger vine will only last for three seconds, even if Ye Chen can plant three trees at the same time now, he can't keep planting the stinger vine all the time, constantly consuming the koala's HP, and there is almost twenty seconds of free time in the middle, within these twenty seconds, the koala can greatly recover the HP without being damaged.

It seems that this last resort can't help Koala, but Ye Chen just came up with another way after frowning!

Or the Stinger Vine!

However, this time, Ye Chen planted the three stinger vines into a large triangle that was not closely connected!

Pulling the koala towards the stinger vine again, this time, Ye Chen first let the stinger vine be in a resting state, so that even if the koala walked on it, it would not be attacked by the poisonous surname.

It wasn't until the koala had walked a distance of almost a meter on the first stinger vine that Ye Chen let the stinger vine start attacking.

The stinger vine began to attack, and the koala walked another meter on the first stinger vine, and when it reached the middle part, it was pulled away by the stinger vine and turned around and began to attack the stinger vine.

Ye Chen himself did not rush to attack, but took a mud orchid grass, and walked to a corner of the triangle formed by the three stinger vines first, staring at the hp of the first stinger vine.

The HP of the first stinger vine is rapidly decreasing, and after almost ten seconds, the HP of this stinger vine is gone, and if the koala attacks again, it may be dead!

And at this moment, Ye Chen's staff moved, and in the priority hatred mode, a withered light was used!

The koala immediately abandoned the hundreds of stinger vines left by HP and ran towards Ye Chen.

Since the remaining length of this stinger vine was only two meters, and after walking a distance of two meters on the top, the hatred of the koala was not pulled away, it was still on Ye Chen.

The koala ran towards Ye Chen, Ye Chen did not rush to take him up to the second stinger vine, but waited until three seconds had passed, and Ye Chen turned around and walked towards the second stinger vine with the slow koal.

Like the first one, Ye Chen initially let the stinger vine rest and not attack, and only after the koala walked a meter away from it did he let the stinger vine start attacking like the first one.

And the first stinger vine that was about to hang up, long after the koala left, Ye Chen let it enter a resting state, so that its HP would recover rapidly under the action of the mud wean grass.

The koala also attacked on the second stinger vine for almost ten seconds, and the priority hatred attack was already available for reuse, and the withered light was still in a cooling state, so Ye Chen unceremoniously stepped forward and manually attacked the koala.

Fortunately, he used a golden staff, and the physical attack on the staff was not bad, Ye Chen barely broke through the koala's defense, and the koala immediately chased after Ye Chen.

Ye Dust led the koala towards the third stinger vine.

The process of bringing to the third stinger vine was no different from the second one, and after more than ten seconds, Ye Chen led the koala to the first stinger vine.

When the botanist's plants are resting and not attacking, the recovery speed will be very considerable, and with the effect of the mud weed, in the past thirty seconds, the HP of the first stinger vine has been completely restored to its full value!

In this way, a constant and sustainable surname attack on koalas is formed!

Although the damage of the stinger vines is low, and the koala's blood falls very slowly, it has been decreasing, and after Ye Chen grinded this guy like this for ten minutes, the koala finally fell to the ground and burst out a somewhat ancient key!

"Grandma's, it's so hard to deal with!"

Seeing this, Ye Chen finally breathed a sigh of relief.

If it weren't for the Eternal Stone, the botanist would have dealt with this guy alone.

"Stinger vines fight this kind of stupid boss, although it is a little slower, but it is very useful."

Thinking of the process of killing koalas, Ye Chen knew that this method was very effective against the boss, but Ye Chen also knew that although this method was effective, it also had to make the boss a stupid level, and if he encountered a long-range attack, it would have no effect at all.

And except in the early stage of the game, most of the bosses are physical attacks, and in the middle and late stages, there are few bosses who can't attack remotely, and it's very difficult for the stinger vines to play their current role again.

Shaking his head, Ye Chen didn't think too much, took the treasure chest key, and walked to the treasure chest in the corner.

After he killed the koala, the treasure chest in the corner, which had originally looked gray, emitted a dazzling golden light!

What luck! It's a golden chest!

If you open equipment, you will find at least a gold chest in this chest, and there is a small chance that a higher level of equipment will be opened!

If it is an item, the value of this item will definitely not be lower than that of gold equipment!

It's sent!

Looking at this golden treasure chest, Ye Chen couldn't help but be slightly excited in his heart!

If you want to encounter a golden chest in the wild or in a dungeon, the chance is very small!
